NERC’s recently submitted Interregional Transfer Capability Study (ITCS) is “a phenomenal first step,” according to participants in a webinar hosted by the American Council on Renewable Energy and Americans for a Clean Energy Grid — but there’s still much work ahead to address the U.S. grid’s mounting reliability challenges.
Speakers at the Nov. 25 webinar included former FERC Commissioner Allison Clements; Robert Taylor, vice president for transmission and new markets at Invenergy; Michael Goggin, vice president at Grid Strategies; and Cy McGeady, a fellow for energy security and climate change at the Center for Strategic and International Studies (CSIS). ACORE and ACEG hosted the forum to discuss the implications of the ITCS and potential future steps for FERC, Congress and other stakeholders.
The ERO worked with the regional entities and transmitting utilities for 18 months to develop the three-part report, which FERC will post for public comment. A final installment focused on transmission between the U.S. and Canada, and between Canada’s provinces, is planned to be released in early 2025.
In the ITCS, NERC recommended 35 GW of additional transfer capability across transmission planning regions in North America to strengthen grid reliability, including two new connections between ERCOT and neighboring regions. (See NERC Releases Final ITCS Draft Installments.) The report’s authors emphasized the analysis did not account for economic issues and cost-benefit analysis, and that even with the recommended additions it would not be possible to resolve all energy deficiencies due to chronic “wide-area resource shortages.”
In ACORE’s webinar, McGeady called the ITCS an “excellent starting point” and a “baseline” for future studies. Similarly, Goggin said NERC and its collaborators “did a great job in really tight time constraints and with the pretty narrow scope that Congress gave them.”
At the same time, attendees said the narrow scope meant that NERC ended up performing a conservative analysis. Goggin said the 35 GW recommendation represents “a floor, in my view, of what you should be thinking about in terms of an optimal transmission expansion.” He noted that FERC tasked the ERO only with identifying “prudent” transmission additions to improve reliability, which meant the study understandably did not take some important factors into consideration.
“Basically, it’s just keeping the lights on. It’s not looking at the opportunity to reduce consumer costs by giving them cheaper power,” Goggin said. “More importantly, even on the resource adequacy side, it’s not looking at how transmission can help you share generating capacity. … The NERC study did look at this, but they didn’t look at how you could economically save on building power plant capacity by tapping into” neighboring regions’ generation.
McGeady added that the figures NERC used to estimate demand were based on the ERO’s 2023 Long-Term Reliability Assessment. He said the projections in this year’s LTRA likely were to be “profoundly larger, like significantly upward revisions.” This means the ITCS’ recommendations could turn out to be even more conservative than Goggin and other panelists thought.
Moderator Elise Caplan of ACORE suggested these concerns could be taken up by respondents when FERC opens comments on the study, along with how to meet the additional unmet needs that NERC identified.
Asked what actions FERC could take to improve reliability through interregional transmission ties, Clements said she believes the commission can play a significant role. She called on FERC to take the lead on interregional planning and on the cost allocation process.
“I think if you’re really, genuinely trying to get to reliability at this moment in time, across the systems that constitute this nation’s electricity systems, we need to be looking at all the tools in the toolbox,” Clements said. “When it comes to reliability, there’s often a quick jump to say you can’t retire the uneconomic thermal units that want to retire. … I think it’s imperative on the commission to say what are the quick, easy, fast ways to do that.”
“I wasn’t a champion of transmission just because I think transmission is great. In fact, it would be a lot easier if we didn’t have to build it,” Clements added. “I’m a champion of transmission because it is a way to get to cost-effective reliability for customers.”
VALLEY FORGE, Pa. — Stakeholder opinions were sharply divided at the PJM Members Committee’s meeting Nov. 21 regarding RTO proposals to allow high capacity factor resources to be sped through the interconnection queue and revise aspects of the capacity market.
The Reliability Resource Initiative (RRI) would advance 50 interconnection requests to Transition Cycle 2 (TC2) — an interim group of queues established as part of PJM’s interconnection process overhaul that began in 2023 — in an effort to address a possible resource adequacy gap identified in the 2029/30 delivery year. The proposal would require tariff changes to be approved by the PJM Board of Managers and FERC. (See Stakeholders Divided on PJM Proposal to Expedite High-capacity Generation.)
Presenting the RRI, PJM Director of Interconnection Planning Donnie Bielak said the proposal is being brought to address “unique circumstances” and would be a one-time measure to allow uprates and resources that can quickly come online to be expedited through the queue to address a reliability need.
If more than 50 projects are submitted, selection would be based on a scoring formula that awards up to 35 points to projects based on their unforced capacity (UCAP); 35 points for the viability of being in service by June 1, 2029, or sooner; 20 points for higher effective load-carrying capability ratings; and 10 points for site location. The only hard eligibility requirements would be that a project must have a UCAP above 10 MW and that they are not part of a project under FERC Order 1000’s State Agreement Approach.
Resources not already subject to the requirement that they participate in the capacity market would be compelled to offer for at least 10 delivery years. Bielak said developers would have the choice of accepting a must-offer requirement for a project they are truly certain can be rapidly brought to market or wait to be sorted into TC1.
TC2 was open to projects sorted into the AG2 and AH1 queues, the latter of which closed in September 2021. Studies on projects submitted after that date are not likely to initiate until 2026.
Responding to stakeholder questions regarding the scale of the impact the RRI could have on TC2 cost allocation, Bielak said PJM does not know which projects will be submitted, and there are hundreds of projects that dropped out of the interconnection process that could be resubmitted. Potential cost allocation impacts vary significantly depending on which projects are submitted and ultimately selected by PJM.
Criticisms and Alternatives
Several renewable developers objected to the proposal, arguing it would constitute queue jumping and disrupt network upgrade cost allocation for projects that have been waiting in the queue for years.
Rahul Kalaskar, AES senior director of regulatory affairs, offered an alternative from AES Clean Energy and REV Renewables to run TC2 and RRI projects in separate cycles. The RRI projects would be added to the separate cycle, which starts after Decision Point 2 of the TC2 cycle and runs all the studies in one condensed process. Doing so would keep the network upgrades for the TC2 and RRI projects in two different buckets.
Kalaskar said that if PJM’s RRI design were to proceed, transmission headroom could be consumed, increasing the costs assigned to TC2 projects and possibly causing some to drop out of the queue.
Steve Lieberman, vice president of transmission and regulatory affairs for American Municipal Power, said his organization conditionally supports RRI if changes are made to the scoring weights to prioritize project size and viability; projects that would be part of fixed resource requirement (FRR) plans are excluded; and developers are prohibited from buying out of their obligations.
Tonja Wicks, vice president of regulatory affairs for Elevate Renewables, said “project viability” and the “in-service date” should account for at least half of the project weighting, as it gets to the core issue that PJM is trying to resolve with the RRI: getting capacity that has the most certainty to come online by a set date. Otherwise it risks selecting projects that promise to bring a large amount of power, but with no firm site control or demonstration that they can meet milestones.
Independent Market Monitor Joe Bowring said the RRI should be preserved as a permanent option that PJM can deploy when it identifies reliability needs that can be resolved by expediting new development. Because projects are being fast-tracked to resolve capacity needs, he said the 10-year must-offer requirement should be expanded to the lifespan of the asset.
Mike Cocco, senior director of RTO and regulatory affairs at Old Dominion Electric Cooperative, said data center loads in northern Virginia are accelerating rapidly, and the RRI is necessary to ensure PJM can continue to meet demand. He said ODEC intends to submit projects to be studied under the RRI, possibly including combustion turbine generators, and he encouraged PJM to consider how the milestone deadlines for RRI projects could conflict with timelines for air quality regulations and other requirements.
“We’re in a position to bring generation online with the timeline that you’re looking for,” he said.
Grant Glazer, MN8 Energy’s manager of regulatory and market affairs, highlighted that projects in TC2 will be studied under a new generation deliverability test, which he said could identify violations prompted by projects in TC1. The status quo rules would assign those network upgrades to TC2 clusters, increasing their cost allocations for up to two-thirds of projects in the cycle. Instead, he encouraged PJM to revise the Regional Transmission Expansion Plan to capture those upgrades.
SIS Eligibility
Along with the RRI proposal, the filing with FERC would include tariff revisions to expand eligibility for projects seeking surplus interconnection service (SIS) by striking language prohibiting projects that could impact the network upgrades for new service customers in the queue.
Stakeholders argue the language is overly prohibitive and prevents developers from co-locating thermal resources with renewables and storage.
Sarah Toth Kotwis, RMI senior associate, said SIS is the fastest process available for bringing new resources online. Storage co-locating with existing resources can come online within 2.5 years of receiving an interconnection agreement, about half the time for adding new generation.
Wicks said PJM stands alone among RTOs in studying open-loop batteries as discharging in light load cases and using those outcomes to determine whether projects would consume headroom that could be used by other queue projects.
“With short duration times for construction and energizing, batteries are the types of resources FERC’s SIS directive envisioned utilizing excess capacity — a.k.a. surplus — at existing facilities to meet resource shortfalls and enhance reliability,” Wicks said.
PJM CEO Manu Asthana said RTO staff are open to revisiting the light load case test for storage, but that needs to be a discussion in the stakeholder process to ensure there are no unintended consequences. The tariff changes would remove barriers to allow that conversation to proceed.
Asthana said his read on stakeholder impressions on the proposed SIS changes is that PJM is on the cusp of resolving their core concerns about the service. He said PJM is taking that feedback and plans to continue pursuing changes.
“The door is not closed: We want to hear how we can make that work,” he said.
Bruce Grabow — a partner in Sheppard, Mullin, Richter & Hampton — urged PJM to take more time to vet the proposal through the stakeholder process, noting that stakeholders had only a few minutes to make their comments during the meeting, with some rushing to include all of their arguments. That is not how the stakeholder process is supposed to occur, he said.
Because of the lack of discussion, along with his assertion that PJM still had not provided data to stakeholders supporting the need for expedition, the RTO risks protests at FERC and in court, Grabow argued. He asked questions about the weighting system PJM intended to apply to determine which new generation projects would be winners and losers and whether the scoring means would be transparent; when PJM did not provide further detail, Grabow argued that meant the criteria would be subjectively applied, which does not comport with FERC standards of transparency, non-discrimination and preference.
Asthana said there is a need for as many TC2 projects as possible — ideally all of them — to be interconnected. He encouraged members to submit written comments by email, with directions provided in a communication to members. Comments will be accepted through Nov. 27, with staff aiming to submit a filing to FERC about Dec. 9, if the board approves the proposal.
“It felt like people had more to say, and we do want to hear what you have to say,” Asthana said.
Proposal to Modify Capacity Market Components
PJM also consulted with the MC at the meeting on a separate proposal that would revise the capacity market to include the output of some resources operating on reliability-must-run (RMR) contracts as supply, revert the reference resource to a dual-fuel CT, and remove the reactive compensation component of the energy and ancillary service (EAS) offset. (See “Insight into Upcoming Filing,” FERC Approves PJM Capacity Auction Delay.)
The 2026/27 Base Residual Auction (BRA) would be the first to use a combined cycle generator as the reference resource, a change that was made in the most recent Quadrennial Review. The higher EAS revenues for CC generators over a combustion turbine unit pushed the net cost of new entry (CONE) value to zero, affecting several parameters derived from net CONE. The variable resource rate (VRR) curve, which defines the slope of the demand curve defining auction clearing prices, would become substantially steeper, and the Capacity Performance penalty rate would fall to zero. (See “Price Cap Increases in 2026/2027 BRA Planning Parameters,” PJM MIC Briefs: Sept. 11, 2024.)
Even with the change, PJM’s Adam Keech said some locational deliverability areas (LDAs) still could see a $0 penalty rate because of the forward price estimates showing a widening spread between gas and electric prices, increasing EAS revenues for all categories of gas generation. The final net CONE will not be known until PJM completes the process of posting the revised planning parameters.
The proposal aims to address those regional impacts by replacing zonal nonperformance charge rates with a uniform penalty derived from the RTO-wide net CONE. Keech said doing so would also reflect the regional emergency capacity deployments PJM tends to experience.
Paul Sotkiewicz, president of E-Cubed Policy Associates, questioned if PJM has examples of dual-fuel CTs being built in the RTO’s footprint within the past five years, adding that the necessary air quality permits to run the backup fuel would be almost impossible to get in many areas, particularly in the regions capacity is needed most.
The reference resource has “to be a resource that can be realistically built,” he said.
Keech said PJM considered several restrictions that would affect the viability of virtually all technologies and looked for the lowest-cost resource that viably can be built. If it were entirely impossible to build a dual-fuel CT across the RTO, the technology would not qualify to be the reference resource, but staff believe there are enough regions where such a unit could be sited to proceed.
Vistra’s Erik Heinle, also speaking for Calpine and LS Power, said a single-fuel CT would be more appropriate as the reference resource by virtue of being viable to build in a wider range of locations.
Constellation Director of Wholesale Market Development Adrien Ford said CTs are “the pure capacity resource,” and setting it as the reference resource would reduce the impact of higher energy revenues on the capacity market.
The inclusion of expected output of generators operating on RMR agreements is aimed at Talen Energy’s 1,273-MW Brandon Shores and 702-MW H.A. Wagner generators outside Baltimore. It would pertain only to agreements accepted by FERC by Feb. 6, 2025, and require that the units be able to operate for the entire delivery year; have sufficient run hours to address transmission violations and capacity emergencies; have deliverable CIRs; and be available for dispatch under emergency conditions unless on outage. The changes would be effective for the 2026/27 and 2027/28 delivery years while stakeholders pursue a more permanent approach to how RMR units interact with the capacity market.
Keech said it is not clear that Brandon Shores would be able to operate in accordance with those requirements because of an agreement with the Sierra Club that mandates that the plant cease coal combustion by the end of 2025, with no plans apparent to convert to alternative fuels. Wagner Unit 3 likely meets all of the criteria, but the RTO still is investigating whether Unit 4 has sufficient run hours to address the transmission needs and be available as capacity.
The RMR units would not be required to take a capacity obligation or enter into BRAs and therefore would not be subject to CP penalties nor included in the balancing ratio. Rather than paying the RMR units as if they had taken a capacity obligation, the proposal would collect capacity revenues and allocate them as credits to consumers assigned a portion of the costs associated with the RMR agreement.
LS Power Vice President of Wholesale Market Policy Dan Pierpont said PJM should ensure that it is considering how the run hours for each of the Talen units may interact. If Brandon Shores cannot operate because of the Sierra Club agreement and Wagner then needs to run more often to resolve transmission violations, that would affect its ability to meet the requirements to be modeled as supply. Keech responded that PJM would address any such interactions.
ACES Power Executive Director of Regulatory Strategy John Rohrbach said PJM is in a bind where it’s likely the Talen units will run through some avenue — either through a modification to the Sierra Club agreement or an emergency order from the U.S. Department of Energy under Federal Power Act 202(c) — but it does not have concrete knowledge of how the generators will be available. He said if PJM believes the RMR units will run one way or another, their output should be modeled.
The third prong of PJM’s proposal — to remove compensation for generators providing reactive service from the EAS offset — is in line with a FERC order finding that consumers cannot be charged for reactive service within a standard range (RM22-2). The commission’s Oct. 17 order provided PJM with more time to submit a compliance filing to determine a transition mechanism to eliminate reactive service, but it also required a separate filing to address how it is reflected in the EAS offset.
The proposed change would be a severable component of the filing, allowing FERC to approve or deny it separately from how it rules on other aspects of the proposal. (See “PJM Details Path Forward on Reactive Power,” PJM MIC Briefs: Nov. 8, 2024.)
BALTIMORE — Getting storage online in Maryland could be a critical piece of the solutions needed to address the sky-high capacity prices PJM recorded in its most recent auction, according to a panelist at a solar and storage conference.
“This is a hands-on-deck moment for Maryland to get these technologies on board,” said Joel Harrington, director of government affairs for REV Renewables, a solar, wind and storage developer. “Sitting in the PJM queue right now, just for transmission-connected storage, are 17 projects … [that] can come online in the next few years.”
Totaling 1.6 GW, those projects represent only the queued-up storage that would be located in Maryland, Harrington said, and getting them online, while not a panacea for PJM’s capacity market problems, is essential. What state regulators, the industry and other stakeholders need to figure out is “what’s going to attract, what’s going to send appropriate price signals” to developers, he said.
PJM capacity prices increased nearly tenfold in the 2025/26 Base Residual Auction in July, jumping to $269.92/MW-day, far above the $28.92/MW-day for the 2024/25 auction. Prices in some parts of Maryland and Virginia hit $466.35/MW-day and $444.26/MW-day, respectively. (See PJM Capacity Prices Spike 10-fold in 2025/26 Auction.)
Harrington and other panelists at the Chesapeake Solar and Storage Association’s Solar Focus 2024 on Nov. 20 debated the options for accelerating deployment of residential and both distribution- and transmission-tied storage, as outlined in a recent report from a Maryland Public Service Commission “workgroup.”
With the passage of H.B. 910 in 2023, Maryland set ambitious targets for getting new energy storage on its electric system — 750 MW by mid-2028; 1,500 MW by mid-2031 and 3,000 MW by mid-2034 — with the goal of creating a “robust and cost-effective” storage market in the state.
The Maryland Energy Storage Initiative (MESI) Workgroup Phase 1 report is aimed at kick-starting the state market to hit the first 750-MW target. Plans for phases 2 and 3 will be developed in subsequent reports.
The workgroup recommends a multipronged approach to market development with a potential mix of utility and third-party owned storage both behind and in front of the meter, including rooftop residential and distribution- and transmission-tied projects.
In front of the meter, utilities might develop their own distribution- or transmission-tied storage or procure projects from third-party developers, the report says. The behind-the-meter market might get a boost from other state programs being developed under other laws, such as the Distributed Renewable Integration and Vehicle Electrification (DRIVE) Act (H.B. 1256), which promotes the aggregation of renewables and storage in virtual power plants.
Another new law, H.B. 864, allows behind-the-meter energy storage to be integrated into utility demand response programs as part of a state energy conservation program.
The report stresses the integral role of aggregation in market development, not only within but also across different programs and storage sectors.
“While the financial, environmental and equity-related benefits and costs of individual storage deployments and programs should not be ignored, it is important to focus on designing an energy storage market that maximizes the aggregate value of all energy storage deployments and the entire portfolio of MESI programs for the grid, ratepayers and the state’s policy goals,” the report says. “Some benefits that storage can provide can only be realized through the aggregate behavior of many devices, and therefore these benefits can be difficult to measure at an individual project or program level.”
Non-monetizable Benefits
The MESI Phase 1 report was submitted to the PSC on Oct. 1, kicking off a comment period that ended Nov. 7. The commission is reviewing the comments and will issue an order, though no time frame has been mentioned, according to an email from a PSC spokesperson.
The panelists agreed that a core challenge for state regulators will be setting up market structures that allow storage projects to be fairly compensated for the full range of services they can provide to cut costs for consumers.
The workgroup report recommends upfront incentives in some instances, which could be critical in the residential market, said Jamie Charles, manager for grid services policy at Sunnova, a residential developer.
While cost savings are the main motivation for homeowners to install solar, “storage is really developed for resilience,” Charles said. “So, by providing these upfront incentives and providing these proposals for these grid services programs and these virtual power plant programs, that’s going to really reduce that barrier to entry.”
The report sees either the Maryland Energy Administration or individual utilities setting and distributing such incentives, which could provide a “strong foundation” for the expansion of the residential storage market in Maryland, Charles said.
Kavita Ravi, senior vice president at BlueWave Energy, a solar and storage developer of distribution-level projects, argued commercial projects should not have to pay demand charges that commercial generation projects typically pay.
“There are several benefits that storage can provide that are non-monetizable, so it’s kind of an unfair market overall,” Ravi said. “In order to allow storage to take off in the electric distribution grid, we think it is important to not levy demand charges during charging.”
Utility demand charges usually are based on specific times of highest demand; for example, when extra power is needed on cold winter days or hot summer afternoons. But for storage, demand charges often are based on the assumption that a project always will charge at its maximum capacity, which the industry has argued is not realistic.
Ravi pointed to the concept of a “wholesale distribution tariff” being developed in the Northeast specifically for storage, which “will fairly apportion the transmission costs and then the charging costs as well, which is more thoughtful and fair for storage.”
For transmission-tied storage, Harrington wants multiple options as well, including full- and partial-toll contracts and upfront incentives. A full-toll option “would be a power purchase agreement or long-term contract where you would contract for energy, ancillary services and capacity, so all three of the attributes would be a fixed price,” he said.
A partial toll would be a fixed-price contract for capacity only, with developers free to bid into either energy or ancillary services markets.
Balancing State and Local Control
Flexibility will be critical going forward, Harrington said. “Our markets [are] changing. The uncertainty around the [Inflation Reduction Act] is really making us question, how do we monetize these assets in the next four or five years? So, we need to be nimble.”
All the different procurement and contract options will “attract energy storage at some level,” Harrington said. “Every business is going to have a different option as to which one is going to attract the best investment for their business.”
The panel also talked about the need to streamline interconnection and for state standards on permitting and siting, while still allowing some flexibility for local control.
While developers will continue to look for project sites that are “non-conflict prone,” Harrington called for “the state establishing specific standards, instead of this patchwork of a developer going into each community, each town [where} they have their own set of rules and ways of regulating and permitting projects.
“The balance is being cognizant of local control, respectful of local control … but having siting standards, ordinance standards that communities can at least follow as a base,” he said.
VALLEY FORGE, Pa. — The PJM Markets and Reliability Committee on Nov. 21 endorsed a proposal to create an expedited process to study interconnection requests that would reuse the capacity interconnection rights (CIRs) of a deactivating resource.
The tariff revisions, proposed by East Kentucky Power Cooperative and Elevate Renewable Energy, were approved with 77% sector-weighted support and added to the Members Committee’s consent agenda, which also passed during the committee’s meeting later that day. (See “CIR Transfer Proposal Discussed,” PJM MRC Briefs: Oct. 30, 2024.)
Under the proposal, PJM would study replacement resource requests in parallel with projects sorted into the standard interconnection queue with the aim of offering developers an interconnection agreement on an eight- to 10-month timeline. To minimize impacts on queue timelines, CIR transfers would be studied using the most recent phase 2 or 3 grid model developed for queue clusters.
The process could be initiated within one year of a formal deactivation notice being received. The replacement resource would be required to interconnect at the same substation and voltage as the original resource, though it could be physically located elsewhere so long as it ties in at the same point. The maximum facility output and CIRs would have to be equal to or lesser than the deactivating generator.
Paul Sotkiewicz, president of E-Cubed Policy Associates, said the proposal would allow developers to take advantage of transformers and other infrastructure already in place to avoid supply chain issues causing delays to construction across the U.S.
“This is something that helps avoid some of the supply chain issues to get resources on quicker,” he said.
Greg Poulos, executive director of the Consumer Advocates of the PJM States, said his members were divided on the motion, with some supporting it as an improvement that would speed development. Others are concerned that interconnection would remain too slow, in part because of the ability for generation owners to wait a year before transferring CIRs, and preferred a design the Independent Market Monitor offered during deliberations at the Planning Committee. If the MRC had not endorsed the proposal, Poulos said some advocates intended to move the Monitor’s proposal as an alternative.
The Monitor’s package would have prohibited bilateral exchange of CIRs and instead created a PJM-administered process to shift headroom from retiring resources to any project in the queue or proposed by a developer that could resolve transmission violations associated with that deactivation.
A third proposal sponsored by PJM at the PC was closer to the endorsed proposal — allowing CIRs to be traded after a deactivation — but would have imposed tighter eligibility limits, including outright barring storage, and required that any replacement resources that prompted network upgrades or would consume available headroom be removed from the expedited process and directed to submit an application to be studied under the wider queue.
The language endorsed by the MRC and MC would allow projects with network upgrades to proceed so long as they cover associated costs. Developers also would be permitted to reduce the scope of a project to avoid network upgrades before proceeding.
The EKPC-Elevate proposal received 51.8% support at the PC during the Oct. 8 vote, while PJM’s design received 40.6% and the Monitor’s received 11.1%.
Monitor Joe Bowring said he does not believe the expedited process would be an improvement, and PJM would continue to face challenges attracting new entry. He suggested it should expand its Reliability Resource Initiative to be retained as a long-term tool to speed interconnections when reliability issues are identified. The initiative — an in-development, interim accelerated interconnection process — would open 50 slots for high capacity factor projects to be added to Transition Cycle 2, allowing them to be studied in advance of projects that have yet to receive a queue position.
He argued that a private, bilateral CIR trading process would introduce delays and create market power for holders of existing CIRs. Owners of deactivating assets would be able to pick the highest bidder for the replacement resource, rather than PJM being able to select the projects that would have the highest impact. Intermittent and storage replacement resources also would not be required to offer into the capacity market, meaning they may not provide the reliability benefit PJM is seeking through the process.
Third Phase of Hybrid Resource Rules Endorsed
Stakeholders endorsed by acclamation a proposal to implement the third phase of PJM’s hybrid resource rules, expanding the model to include non-inverter-based generation paired with storage.
The language is slated to be voted on by the MC on Dec. 18. (See “1st Read on 3rd Phase of Hybrid Resource Rules,” PJM MRC Briefs: Oct. 30, 2024.)
Participation in the energy and ancillary service markets would be along the lines of the Energy Storage Resource Participation Model detailed in Manual 11; capacity accreditation would focus on the storage element of the resource while taking into account the availability of the generation component.
Hybrids with any component subject to the requirement that resources offer into the capacity market also would be subject to the must-offer rule. Hybrids with no component subject to the rule, such as intermittent generation or storage, would not be mandated to participate in the market.
PJM’s Maria Belenky said a friendly amendment was offered following the first read in November to align the binding notice of intent requirement for hybrids with other resource classifications. She said stakeholders pointed out that a different timeline would exist for hybrids than all other planned resources under the original tariff language drafted.
First Read on Quick Fix for Revising Load Drop Estimate Inputs
PJM’s Andrew Gledhill presented a proposal to grant PJM more flexibility to reflect errors in the availability of load management when calculating the unrestricted peak loads component of the load forecast.
The revisions to PJM Manual 19: Load Forecasting and Analysis are being brought as a quick fix — allowing the issue charge and solution to be voted on concurrently — in an effort to have the changes effective for the 2025 load forecast.
Gledhill said the change is intended to account for instances when load management deployments occur at times that participants are operating below their peak load, which would reduce the estimated load drop PJM is likely to receive. That includes holidays when industrial consumers are likely to be offline.
If starting with the premise of peak load contribution rather than what the actual loads would be at that time, Gledhill said it’s likely inaccurate information would be included in the forecast.
PJM’s Pete Langbein said that historically, peak loads were concentrated on hot summer days, but the RTO’s risk modeling has shifted the focus toward winter deployments, when the energy reduction capability can vary more significantly. Load drop estimates are used to calculate unrestricted load for forecasting, capacity compliance and the addback reported to the utility for the following year. The hourly forecasts also are an input into the effective load-carrying capability models used in resource accreditation.
Manual Revisions to Clarify DASR Calculation for 30-minute Reserves
PJM’s Kevin Hatch presented revisions to Manual 13 to document how the day-ahead scheduling reserve (DASR) is used to determine when the 30-minute reserve requirement may be insufficient for procuring adequate reserves.
The Operating Committee endorsed the language as a quick-fix proposal during its Nov. 8 meeting. (See “Stakeholders Endorse Quick Fix Solution on Day Ahead Scheduling Reserve Calculation,” PJM OC Briefs: Nov 8, 2024.)
The 30-minute reserve is set at the greater of 3,000 MW, the primary reserve requirement or the largest active gas contingency, which Hatch said does not reflect the full range of operational risks dispatchers must account for when determining necessary reserves. The DASR calculation accounts for load forecast error and forced outage rates, both of which were factors that PJM sought to include in a dynamic 30-minute reserve formula stakeholders rejected in July. (See “Stakeholders Endorse Reserve Rework, Reject Procurement Flexibility,” PJM MRC Briefs: July 24, 2024.)
Hatch said the revisions reflect an existing practice and no changes are being made to PJM processes.
Manual 14D Periodic Review
PJM’s Madalin How presented a package of revisions to Manual 14D drafted through the document’s periodic review. The changes would correct grammatical errors and typos, and update communication protocols, including adding a new email address.
The manual also would be updated to document that generators must provide reactive capability curves to PJM before they can come online and that reactive testing must be completed within 90 days of initiating commercial operations.
Members Committee
Comment Period Opens on Cost Allocation Tariff Revisions
PJM told the MC that the Transmission Owners Agreement Administrative Committee had opened a 30-day consultation period on revisions to tariff Schedule 12, which details the solution-based distribution factor (SBDFAX) process for allocating the costs of Regional Transmission Expansion Plan projects (EL21-39, ER22-1606).
The revisions would address a FERC order granting a complaint from the Long Island Power Authority and Neptune Regional Transmission System regarding components of the SBDFAX method.
Merchant transmission facilities would be considered “responsible customers” within the zone they are interconnected to be assigned a portion of the transmission enhancement charges associated with RTEP projects. If material modifications are made to the boundary of that transmission zone, merchant transmission owners would have the option to have the DFAX analysis separated from that zone.
Required transmission enhancements approved by the PJM Board of Managers prior to Dec. 11, 2023, will be located in the zone of the relevant TO, while enhancements approved after that date would be located in the zone where the physical enhancements are sited.
Constellation Energy filed a complaint against PJM at FERC on Nov. 22, opening up another regulatory front in the debate over co-locating data centers at existing nuclear plants (EL25-20).
Constellation alleges that PJM’s tariff is unfair because it does not contain rules for interconnected generators to follow when seeking to provide service to fully isolated, co-located load.
“While nothing in the tariff suggests any prohibition of fully isolated co-located load, some local utilities are taking advantage of the lack of tariff rules to thwart competition to serve large end use loads, thereby delaying by several years and significantly increasing costs to serve data centers that are critical to national security, economic development and other national priorities,” Constellation’s complaint said. “This lack of tariff rules is allowing transmission owners across the PJM system to treat generators seeking to serve fully isolated co-located load differently.”
PJM released guidance for the issue in April 2024, which explains how the RTO has been reviewing co-location. The complaint said that should be included in the tariff. FERC might decide that it has to weigh in on other issues, but those could be dealt with in a paper hearing.
The complaint argues that rules are needed so market participants understand what they have to do to enter into generator co-location deals. They also would ensure utilities understand the FERC jurisdictional rules applicable to fully isolated, co-located load and “cease exercising their monopoly power to thwart competition.”
“It is necessary to establish consistency across the PJM footprint and avoid the current circumstance of each of the transmission owners in PJM deciding whether and to what extent they will follow PJM’s guidance,” the complaint said. “Otherwise, we will be left with a mishmash of co-location rules at the federal level that are driven by the self-interests of each of the transmission utilities.”
That mishmash already is starting to happen based on how different Exelon’s pending rules would treat co-located demand compared to how PPL Electric Utilities dealt with the 300-MW data center co-located at the Susquehanna nuclear plant.
Data centers are a national security priority due to the new technologies driving them, such as artificial intelligence. Their increasing size has made them difficult to connect to the grid, as that often requires new transmission. Building out the required lines takes several years and leads to higher costs for other consumers, the complaint said.
“As a matter of simple engineering, it is more efficient to locate large loads next to large generation, when possible,” Constellation said. “One longstanding option that has been available to any load since the beginning of open access has been to connect directly to a generator either fully independent of the network grid or with a reduced reliance on the grid.”
Data centers have pursued contracts for fully isolated, co-located load, “networked co-located load” where they rely partly on the grid and partly on a nearby power plant, and a “networked load” configuration that relies entirely on the grid. The last two have formal rules in PJM’s tariff, but fully isolated co-located load lacks formal rules, with the tariff also saying nothing that indicates the configuration is inconsistent with the RTO’s rules.
The issue of the less formal guidance on co-location came up when FERC recently rejected the expansion of a co-located data center at the Susquehanna nuclear plant. (See FERC Rejects Expansion of Co-located Data Center at Susquehanna Nuclear Plant.) The amendments to the Susquehanna deal were proposed in large part so PJM’s guidance would be binding on the parties.
FERC rejected them in part because it questioned whether the RTO planned to offer interconnection services on equivalent terms to all similarly situated interconnection customers. FERC’s order acknowledged the guidance was “not part of the PJM tariff, has not been approved by the commission and was not before the commission in the instant filing.”
The complaint notes that PJM has completed studies for potential co-located loads at three Constellation generation sites, which indicated none of those would have been able to draw power from the grid.
Exelon reviewed the deal at Constellation’s LaSalle Clean Energy Center in Illinois, but then refused to do so at the other two units, insisting that the generation owner or its customer first must apply for retail service and designate what sort of wholesale transmission service it would take from Exelon. The utility holding company then stopped working with the data center at the LaSalle plant, the complaint said.
Connecting a major data center to the grid can take five to 10 years, and in a global race for new technology, any delay is harmful to the national interest, the complaint said.
“This interconnection delay imposes unquantifiable risks and costs to the national economy and security and advances in AI,” the complaint said. “Each year that hyperscale data centers await interconnection to the grid risks another year of losing ground to competing nations.”
BOSTON — Energy leaders from the U.S. and Canada grappled with the challenges of balancing decarbonization and affordability at the New England-Canada Business Council’s (NECBC’s) Executive Energy Conference on Nov. 20-21, discussing how collaboration could lower the cost of the clean energy transition on both sides of the border.
Retail electricity rates in New England are rising faster than nearly all other regions in the U.S., while Hydro-Québec plans to spend billions of dollars to meet demand growth, which it expects to put “upward pressure on electricity rates.”
To juggle major investments preparing for load growth, upgrading aging infrastructure, and incorporating and balancing intermittent renewables, “there needs to be a different way to look at how the investment is funded,” said Nicola Medalova, COO of National Grid’s New England electric business.
Central Maine Power CEO Joseph Purington echoed Medalova’s concerns, saying the increase of public policy costs in electric rates is “not sustainable.”
“We have to start thinking about public policies and the public policy component of the bill,” Purington said. He wondered if some of those costs should be “spread across as a tax instead of as a part of your electric bill.”
The potential loss of federal clean energy funding with the incoming Trump administration likely will add a layer of difficulty for states looking to meet their climate goals without overburdening ratepayers.
Electricity bills can be a regressive funding mechanism to support public policy initiatives: Rising energy costs disproportionately affect low-income individuals, who often are forced to choose between paying energy bills and covering other essential needs like food and health care.
Discount rates can do only so much to mitigate the issue, Medalova said, adding that rate pressures can drive up economy-wide living costs. “Whenever you give a discount, somebody else is picking up the weight of that bill.”
North of the border, political uncertainty in Canada similarly threatens the availability of federal funding, said Monica Gattinger, a political studies professor at the University of Ottawa. Gattinger said public opinion shows climate change has been “dropping like a stone” in the public’s list of priorities, adding that a conservative government “would likely reverse many, if not all, of these policies.”
Competing Priorities
Speakers at the conference discussed a wide range of solutions to help balance the often competing priorities of affordability, reliability and decarbonization.
Medalova and Purington both emphasized the need to unlock retail demand flexibility, a sentiment that was echoed by several other speakers throughout the conference.
ISO-NE CEO Gordon van Welie highlighted the RTO’s finding from its 2050 Transmission Study that a 10% reduction in the 2050 peak load could reduce the required transmission buildout by about a third.
Winston Morton, CEO of Climative, said there is a large amount of remaining potential in energy-efficiency upgrades. He added that these gains have been constrained by the limited scale of state energy-efficiency programs and the gap in capital needed to finance building retrofits.
“We’ve got to attract private capital into the market as quickly as we can,” Morton said, noting that he sees “a positive return on investment for every retrofit.”
Along with transmission needs, load growth also will pose significant resource adequacy challenges for the Northeast.
“We’ve got to figure out how to balance load growth and electrification efforts with reliability,” said NERC CEO Jim Robb, adding that he is “a big advocate of natural gas generation, because it’s so flexible and it can help meet the afternoon ramp.”
Natural gas is the dominant source of electricity generation in New England, and gas-fired generation has been increasing steadily in recent years.
“There is a critical need for gas throughout the year,” said Richard Levitan, president of energy management consultancy Levitan & Associates.
Toby Rice, CEO of EQT, one of the largest U.S. gas producers, pitched attendees on the need to increase natural gas pipeline capacity into the region.
“We’ve hit a wall,” Rice said. “We just need more infrastructure to connect markets.”
Rice chided environmentalists for opposing pipeline projects and argued that additional gas infrastructure would help reduce emissions by displacing coal or oil.
“They should be supporting pipelines because of their concern for climate,” he said.
While replacing coal or oil with natural gas can bring some emissions reductions depending on how much methane is leaked from the system, coal and oil make up only a small fraction of the generation mix in New England, Québec and the Maritime provinces, apart from Nova Scotia.
Increased gas generation has caused greater power system emissions in New England in the past year, and a long-term rise in gas consumption would likely undermine the climate goals set by New England states. Massachusetts state law includes sector-specific emissions limits with increasingly stringent decarbonization targets through 2050.
Rice also argued that increasing LNG export capacity would drive down global emissions, although the climate case for exported LNG is murky. One peer-reviewed study published in October found exported LNG to have a 33% larger carbon footprint than coal over a 20-year period.
Van Welie expressed skepticism that New England would see new pipelines, citing a lack of customers. However, he stressed that existing resources must not be retired faster than new renewables are deployed, especially with anticipated load growth. An ISO-NE study on deep decarbonization published in October found a significant need for clean, dispatchable resources to balance renewables. (See ISO-NE Study Lays Out Challenges of Deep Decarbonization.) The study singled out small modular nuclear reactors (SMRs), synthetic natural gas and multiday energy storage as potential solutions to help meet these needs.
Rudy Cuzzetto, a member of the Legislative Assembly of Ontario, discussed the province’s work to help commercialize SMRs. Ontario likely will have the world’s first full-scale SMR — with a capacity of 300 MW — in operation by 2029, he said.
“The world is looking at Ontario right now,” Cuzzetto said. “We are going to be a powerhouse in Ontario [and] be able to export electricity across the world.”
Québec’s vast hydropower resources also could help to fill the need for dispatchable power, said Serge Abergel, COO for Hydro-Québec Energy Services.
Despite a drop in exports in 2023 from low reservoir levels, Hydro-Québec has indicated that long-term changes to the role that its hydroelectric resources play on the grid could bring savings across the Northeast. (See Québec, New England See Shifting Role for Canadian Hydropower.)
“We are interested in optimizing our grid for our neighbors,” Abergel said. “Let’s have a conversation on regional planning for the long term. Maybe we can save some ratepayer money.”
In theory, increased bilateral transmission capacity between the two countries could provide significant benefits when paired with a surplus of renewables on the New England grid. This would allow New England to export cheap power during periods of excess renewable generation, while enabling Québec to conserve hydropower and send power back to the U.S. during renewable lulls.
Abergel said the company sees “significant savings, especially when you start looking at 2040 and onward.”
Responding to Abergel’s pitch, van Welie said this dynamic would require agreements to provide “a reciprocal benefit” between regions and to ensure Hydro-Québec sells the power back to New England at a reasonable price during periods of low renewable generation.
California regulators approved a $35 million package of clean transportation incentives for fiscal 2024/25, a steep drop in funding that is raising concerns about the fate of programs not funded by the package.
The California Air Resources Board approved a funding plan Nov. 21 that divides the money among three programs:
$15 million for the Clean Off-Road Equipment project (CORE), which provides incentives for the purchase of zero-emission off-road equipment such as forklifts and cargo loaders.
$15 million for the Innovative Small e-Fleet (ISEF) project, which offers incentives for medium- and heavy-duty ZEVs for fleets of 20 or fewer vehicles. There’s also funding for “innovative solutions” such as truck sharing.
$5 million for the Zero-Emission Truck Loan pilot project to help fleets buy zero-emission medium- and heavy-duty trucks.
This year’s $35 million in clean transportation funding compares to a $624 million incentive package approved in 2023, a record-breaking $2.6 billion in incentives in 2022 and a $1.5 billion package in 2021.
“This year’s state budget was a challenging one, with reductions across the board to many key state agencies and programs,” CARB Chair Liane Randolph said. “Funding allocations for air quality and climate change programs were unfortunately no different.”
While last year’s incentive packages were funded by a variety of sources, including cap-and-trade dollars and the state general fund, this year’s funding came only from the state’s Air Quality Improvement Fund.
CARB Executive Officer Steven Cliff said the funding package is aimed at small fleets and small businesses and seeks to benefit disadvantaged communities. The CORE and ISEF programs historically have had more demand than available funds, said Cliff, adding that though the funding is less this year, it’s “certainly meaningful.”
Programs Left Out
CARB’s approval of allocations to only three programs means other incentive programs will go without additional funding this fiscal year. That includes the Hybrid and Zero-Emission Truck and Bus Voucher Incentive Project (HVIP), which has helped fund the purchase of more than 14,000 medium- and heavy-duty clean vehicles since it launched in 2009.
As of Nov. 21, the HVIP website said the standard voucher portion of the program was out of money. The program still had funds available in certain set-asides, including those for transit and drayage trucks.
Tim McRae, vice president for public affairs at the California Hydrogen Business Council, said the HVIP funding shortfall comes at a “pivotal point” for the fuel cell electric vehicle industry. New manufacturers and new products are entering the market, giving truck buyers more choices, he said.
“We must have incentives in the next six to eight months to get these platforms off the ground. Otherwise, the whole industry, including customers and end users, will suffer,” McRae said during the CARB board meeting.
In contrast to HVIP, McRae said, the ISEF program has less of a track record, and the CORE program targets vehicles that generally don’t emit as much pollution as the heavy-duty trucks that HVIP targets for replacement.
Among the newly available fuel cell electric vehicles is a zero-emission garbage truck that is being tried out in California. The garbage truck was developed by Hyzon in partnership with New Way Trucks.
In a trial with Mt. Diablo Resource Recovery, the fuel cell trucks demonstrated consistent power over a range of at least 125 miles, including at least 1,300 cart lifts, with greater fuel efficiency than traditional diesel trucks, Hyzon said in an announcement this month.
Nick Barrett with Hyzon said the company was on the verge of closing several large orders for the fuel cell trucks.
“HVIP is absolutely required to complete these sales and get these trucks on the road,” Barrett told the board.
Low-income Programs
The funding shortfall also pits two low-income, zero-emission vehicle incentive programs against each other.
CARB’s Clean Cars for All (CC4A) program has been run for several years by air districts in different parts of the state. More recently, at the direction of the legislature, CARB launched a statewide incentive program for residents living outside of the participating air districts.
CARB announced in September the launch of the statewide program, called the Driving Clean Assistance Program, with $242 million of funding. The program allows low-income participants to scrap their old vehicle in exchange for a grant of up to $12,000 to buy a new or used zero-emission car, motorcycle or e-bike.
Now CARB is struggling to balance the funding needs of DCAP, which brings the low-income ZEV incentive to regions where it previously wasn’t available, and the air district’s CC4A programs, which have a track record of bringing incentives to hard-to-reach populations.
Neither received any funding in the new incentive package. But $14 million recently was shifted from DCAP to the San Joaquin Valley CC4A program.
“Unfortunately, we are basically talking about scraps,” said Randolph, the CARB chair. “We are talking about inadequate funding for getting vehicles to residents that could not otherwise afford cleaner vehicles.”
Randolph said she would work with CARB staff on ways to optimize funding among the DCAP and CC4A programs.
ERCOT says it will recommend that its Board of Directors approve a reliability-must-run (RMR) contract for one of three aging CPS Energy gas units, set for retirement, to maintain reliability in the San Antonio area.
The grid operator also told the Texas Public Utility Commission during its Nov. 21 open meeting that it is working with CPS and CenterPoint Energy to determine whether the latter’s controversial $800 million mobile generators could be moved to San Antonio as an alternative.
“I think this is an elegant solution to a number of issues that we’re facing,” PUC Chair Thomas Gleeson said in response.
ERCOT General Counsel Chad Seely told the PUC that grid operator staff, the two utilities and Life Cycle Power, the generators’ owner and operator, have been discussing moving the larger units and their 480 MW of capacity to the San Antonio area. He said the 15 large generators are the equivalent of two of the retiring plants, Braunig Power Station’s Units 1 and 2, and would provide greater reliability than CPS’ forced outage-prone assets.
That comes from “mainly the diversity of where those units can be located versus having two larger units that have the susceptibility of higher forced outages,” he said. “These are dual-fuel-capable units. They could be located in San Antonio with a higher shift factor. And obviously their start time is about 10 to 15 minutes, versus a longer lead time for Units 1 and 2.”
CenterPoint said in an emailed statement that its “top priority is finding a Texas-driven solution that helps address the growing energy needs of Texans and our strong economy.”
“We are optimistic that we will find a constructive solution that best serves our customers and Texas,” the utility said.
San Antonio’s municipal utility told ERCOT earlier this year that it planned to retire the three Braunig units, which date back to the 1960s, in March 2025. However, ERCOT said the resources, with a combined summer seasonal net maximum sustainable rating of 859 MW, were needed for reliability reasons and issued a request for RMR proposals in July. (See ERCOT, CPS Energy Negotiating RMR, MRA Options for Retiring Units.)
In the meantime, Seely said ERCOT will urge its board to approve an RMR agreement for Braunig Unit 3, the newest (1970) and largest (412-MW maximum summer rating) of the three units. It will ask the directors to defer any decision on the other two units so staff can continue to work on the feasibility of the mobile generators’ move. The board meets Dec. 2-3.
CPS has said each unit must be inspected and repaired — consecutively, not concurrently — if it is to operate beyond its retirement date. The utility has moved the unit’s suspension date up to March 2, allowing time for inspection and repairs that it says will take at least 60 days.
“If the board moves forward with an RMR agreement, that will allow us to move forward with that inspection work at the beginning of March in trying to get that unit back for the summer of 2025,” Seely said. “A lot of work has been done on the technical side. We do believe it is technically feasible to move those 15 units into the San Antonio area.”
“There are many factors being evaluated by ERCOT and the companies involved,” CPS spokesperson Miguel Vargas told RTO Insider in an email. “We remain engaged in ERCOT’s efforts to evaluate this alternative proposal.”
ERCOT says the RMR units will be important in addressing the South Texas export interconnection reliability operating limits staff established this year that will eventually be resolved by transmission projects underway. Their analysis revealed that under certain conditions, such as when high system demand coincides with an outage of a major transmission line or one or more generation units, lines that deliver power from South Texas into San Antonio could be overloaded and possibly lead to cascading outages.
ERCOT’s solicitation for must-run alternatives to Braunig’s retiring units resulted in one response. A 200-MW multi-hour energy storage resource responded within minutes of an Oct. 7 deadline, proposing to start in the summer of 2026 and end March 1, 2027.
The RMR contract would be ERCOT’s first since 2016. The grid operator entered into an agreement with NRG Texas Power over a previously mothballed gas unit near Houston. It ended in 2017, thanks partly to transmission facilities that increased imports into the region.
New Rules for Crypto Miners
The PUC approved a new rule requiring virtual currency mining facilities in ERCOT to annually provide information related to their electricity demand, location and ownership, giving the grid operator more transparency into the market (56962).
Under the rule, cryptocurrency miners with a total load above 75 MW will have to register with the PUC as a large flexible load, capable of adjusting their power consumption in response to prices. The facilities must file a five-year projection of expected peak load for each year, including the percentage of load that meets the definition as interruptible. The rolling five-year projection will be repeated each year.
“I think it’s really important that, as we’re looking at [Texas’] load growth, that this help us give ERCOT and the market an understanding of what those actual projections are from the cryptocurrencies’ standpoint,” Commissioner Jimmy Glotfelty said. “Having them look five years out every year is a really important component of this for reliability.”
The rule was mandated by state law as demand associated with virtual currency mining operations has grown rapidly in recent years, according to the U.S. Energy Information Administration.
PUC Completes Beryl Investigation
The commission approved several reports, including its investigation into two major weather events that hit the Houston area: a derecho in May and Hurricane Beryl in July.
At Gov. Greg Abbott’s directive, the PUC assessed local utilities’ emergency preparedness and their response to the two events (56822).
The PUC team made a number of recommendations to reduce the length and effect of power outages, including annual hurricane and storm drills between utilities, new performance standards and heavier fines, and a legal right to restoration timelines.
The investigation’s summary will be added as an addendum to the broader report that all state agencies are required to file ahead of Texas’ biennial legislative sessions. The 2025 session begins Jan. 14.
The PUC also approved:
ERCOT’s biennial report on the operating reserve demand curve, which will eventually be replaced by individual ancillary service demand curves under real-time co-optimization (55999); and
an order finding ERCOT’s proposed ancillary service methodology for 2025 is appropriate and necessary for the market’s proper functioning (54445).
BALTIMORE ― Solar industry veterans often refer to the shifting political and economic fortunes the sector has experienced over the past decade as “the solarcoaster,” and many at the Chesapeake Solar and Storage Association’s (CHESSA) 2024 Solar Focus conference were preparing for a bumpy ride during President-elect Donald Trump’s second term.
But they also spoke about the industry’s resilience, and the fact that it still recorded strong growth during the first Trump administration, supported by state and corporate clean energy goals and ongoing cuts in the cost of solar panels, making solar increasingly competitive with other forms of generation.
An affiliate of the national Solar Energy Industries Association, CHESSA is a regional trade association covering Maryland, Virginia and the District of Columbia, all jurisdictions with ambitious clean energy and emission reduction goals.
Alex McDonough, a partner at policy consultants Pioneer Public Affairs, took a hardline view, predicting that Trump and congressional Republicans could target clean energy tax credits in the Inflation Reduction Act, including the 30% investment tax credit that has been critical for U.S. solar market growth.
In the two-plus years since the law was passed, GOP lawmakers in Congress “have voted 54 times on different pieces of the Inflation Reduction Act to repeal,” McDonough said during a Nov. 19 panel at the two-day conference at the Marriott Baltimore Inner Harbor hotel. “We should take them at their word that they are putting this up on the table, and one of the potentially most damaging pathways to extend the 2017 tax bill that we could experience is if they start out with an opening negotiating position that fully goes after the IRA tax credits.”
The buzz on Capitol Hill is that Republicans in the House of Representatives will have a budget reconciliation package to extend Trump’s signature legislation, the 2017 Tax Cuts and Jobs Act (H.R. 1), ready to introduce in the first week in January, McDonough said. Among its other business-friendly provisions, the law cut the corporate tax rate from 35% to 21%. It expires at the end of 2025, and the anticipated price tag for extending those cuts is about $5 trillion, McDonough said.
Budget reconciliation is a legislative maneuver that allows budget bills to be passed on straight majority votes in both houses, which is intended to protect them from minority party filibusters. The Trump tax cuts and IRA were passed through the budget reconciliation process, as will be any bill to extend the 2017 cuts.
Playing “Pollyanna” to McDonough’s tough pragmatist, Alison Kennedy, vice president at Boundary Stone Partners, another D.C. policy group, talked up the current conventional wisdom that the Republican states and districts that have benefited from a majority of IRA funds will help protect key provisions of the law.
Factories are being built; jobs are being created, Kennedy said. “It’s time for these projects to shine. …
“The communities, the states, those stakeholders; it’s their time to rise. It is their time to be involved in these discussions, to push, to call their Congress members … to say, ‘Yes, the IRA is making an impact in our communities.’”
Ben Norris, vice president of regulatory affairs for SEIA, said the national trade group began preparing to defend the law even before President Joe Biden signed it in 2022. SEIA has been on the Hill meeting with the newly elected lawmakers who arrived in D.C. after the election and will bring its own members into town in December and January to talk with their representatives and senators.
It’s one thing to show lawmakers the facts and figures ― like the 40,000 new solar manufacturing jobs created by the IRA ― Norris said. “It’s quite another to meet the proprietors of such a new facility, who are actually employing these folks in the districts of some of the lawmakers who are going to be taking some of these hard votes.”
But both he and McDonough cautioned against depending too much on support from certain Republicans — for example, the 18 GOP representatives who in August sent a letter to House Speaker Mike Johnson (R-La.) asking for protection for the IRA tax credits that are benefiting their constituents.
Republican majorities will be slim in both houses, so GOP lawmakers could have little wiggle room on a budget reconciliation vote to extend the 2017 tax cuts, McDonough said.
“If we get to a point where there’s a tax bill on the floor that extends the 2017 tax cuts and includes all the IRA provisions in there, cutting them in any which way, they will vote for it,” he said. “They will have to vote for that bill for political reasons; because if that bill fails, they will be responsible for an income tax hike for every American.”
An Industry That Adapts
With Trump returning to the White House, renewables — solar, wind and storage ― are facing a major change in the political and social narratives surrounding the industry. For four years, the industry has benefited from current Energy Secretary Jennifer Granholm’s urgent calls to “deploy, deploy, deploy” clean energy projects.
But North Dakota Gov. Doug Burgum (R) and fracking executive Chris Wright, respectively Trump’s picks to lead the Interior and Energy departments, will be pushing a “drill, baby, drill” agenda aimed at “U.S. energy dominance” and “energy independence.” Trump is calling for a buildout of baseload energy — that is, natural gas or possibly nuclear ― aimed at cutting consumer energy prices.
The anticipated retreat from President Joe Biden’s clean energy goals — such as a 100% carbon-free electric grid by 2035 — already is refocusing industry attention, and hopes, toward states and cities, like Maryland, Virginia and Washington, D.C., that have passed strong clean energy policies.
Maryland has committed to a 60% reduction in the state’s greenhouse gas emissions by 2031, while Virginia’s Clean Economy Act of 2022 mandates the state’s two investor-owned utilities — Dominion Energy and Appalachian Power — to provide 100% clean generation by 2045 and 2050, respectively.
Kennedy and others expect that Trump’s other policies, such as tariffs on all imports, will increase utility bills. “I don’t have a solution for how to make them not go up,” she said.
She sees an opening for renewables if the new administration truly gets behind an “all-of-the-above” approach to energy policy and the solar industry positions itself as integral to the Trump narrative of energy dominance and independence.
Solar and storage are critical to meeting new demand from data centers and together accounted for about 80% of new power on the grid in 2024, Kennedy said, citing figures from the U.S. Energy Information Administration.
“How are we showing what manufacturing jobs are leading to this and telling those stories and drawing those lines to conclusions to allow Republicans to see the benefits and how we are manufacturing and deploying domestically,” she said. “It’s hard to argue with jobs.”
Norris noted that the U.S. solar industry is slated to hit a major milestone by the end of the year, with domestic supply chains producing enough solar panels — about 40 GW of capacity ― to cover current demand, according to figures from SEIA and industry analysts Wood Mackenzie.
“That means no more modules from overseas, potentially,” he said. “The idea of making all that go away through a sort of arcane piece of tax and financial legislation, I think it’s going to be unappealing to most.”
But Walter McLeod, managing director of Monarch Strategic Ventures, which invests in clean energy, said Republicans could undercut the solar ITC through further corporate tax cuts. In 2017, Trump had proposed cutting the corporate tax rate to 15%, but settled for 21%, McLeod said during a panel on federal policy Nov. 20.
“We should all expect that he’s going to take a second bite at [that],” he said. “When the number goes below 18% … the demand for the ITC at the corporate level will substantially drop off, and that could crush the market indirectly.”
In other words, if corporate taxes are low enough, companies may not have the “appetite” or need for the tax credits generated by solar development.
But McLeod and other speakers on the Nov. 20 panel also see new opportunities for the industry as it navigates wherever the solarcoaster takes them in the days and months ahead.
“We’re an industry that adapts,” said Lara Younes, director of mergers and acquisitions and structured finance at Lydian Energy, a utility-scale solar developer. “We’ve already experienced a bunch of headwinds over the last years, and I think we should continue to be flexible, … optimistic and creative in whatever way we can.”
Ian Gallogly, vice president of acquisitions for CleanCapital, which invests in and owns solar and storage projects, said a focus on performance, outcomes and national security, sometimes favored by fossil fuel companies, also could work for renewables.
Robin Dutta, executive director of CHESSA, argues that the intermittency of solar or other renewables is being misrepresented.
The intermittency narrative ― the sun doesn’t always shine, the wind doesn’t always blow — doesn’t take into account that renewables provide multiple, diverse options to meet growing demand in the U.S., Dutta said.
“You have wind; you have land-based wind; you have offshore wind. You have residential solar and [commercial and industrial] and large-scale, and you’ve got energy storage, short-duration … behind-the-meter, standalone,” he said. “We have all of these solutions. Between solar and storage, we can play such a huge role in American energy dominance.”
CARMEL, Ind. — MISO further embraced the industry’s move to chance-based transmission planning by hosting a Probabilistic Planning Symposium at its headquarters.
The grid operator and consulting firm Energy and Environmental Economics pulled together stakeholders, other RTO planners, researchers and tech representatives to probe prospective planning methods and fret over the shortcomings of current practices Nov. 19-20.
Director of Economic and Policy Planning Christina Drake said when she joined MISO, planning was carried out on a relatively gradual timeline compared to the urgency today.
“We’re seeing these loads come on quicker than we can keep up,” she told attendees.
Drake said of late, MISO is having “friendly but frank” conversations with companies whose building goals are stymied by the limits of today’s transmission capacity.
She said just a few years ago, MISO was met with skepticism that its third, most aggressive planning scenario — which predicted electrification stimulating significant demand — would ever come to pass.
MISO announced earlier in November that it will revise its three, 20-year transmission planning futures — which envision the clean energy transition at a walk, a jog and a run — to be more in touch with recent realities of surprising load growth and accelerated clean energy goals. (See MISO Pauses Long-range Tx Planning in 2025 to go Back to the Futures.)
“And now we’re getting feedback that we think you’re near your top end on your load [predictions],” Drake said. “The drivers are changing. It’s no longer electrification; it’s things with hydrogen and data centers. That’s very different.”
Drake said the pace of change is so dramatic that MISO’s planning modeling is becoming unsolvable. “Our tools have never seen this. It’s pushing our models to the brink,” she said. “Now we’re projecting things 10 years faster.”
SPP Manager of Transmission Planning Kirk Hall seconded experiencing trouble trying to produce realistic models.
“We’re having to constantly add fictitious equipment … just to get our reliability models to solve,” he said.
“If you’re asking if the probabilistic planning tools are sufficient? The answer is no,” NYISO Director of System Planning Yachi Lin said.
Lin said New York’s past 35 years contained little in the way of transmission planning. Recent years, on the other hand, have contained about $15 billion in transmission and distribution investment, she said, owing to the state’s progressive climate goals.
Lin said New York City alone has an “acute” problem of having to retire several aging, combined cycle units, while new, zero-emission generation needs to occupy as little acreage as possible. She said advanced technology is years away, with a “big gap of getting there.” Lin likened transmission planning around those unknowns to layering up slices of Swiss cheese.
“There are holes, we know. But hopefully, if you have enough slices, you can cover the gaps,” she said.
Drake said building an economic model takes an amount of work that’s often not appreciated. She said it’s a level of challenge that’s on par with delivering a baby.
“It took a solid nine months, and there was a lot of crying and pain in the middle,” she joked of creating a successful model.
Drake added that just to get a model to solve today takes an “intense” effort. She said she felt like bringing planners a “Gatorade and a towel” after they’re successful.
ERCOT Power Systems Engineer Eric Meier also said that there aren’t any tools “off the shelf” today that can effectively evaluate probabilistic planning.
Drake said grid planners’ challenges are compounded by trying to anticipate yearly bouts of increasingly extreme weather and generation outages.
“This is new territory for all the RTOs,” she said.
Drake said extreme weather instances are driving an “insatiable” need to improve interregional transfer capability, evidenced by MISO’s new interregional studies with SPP and PJM.
During the symposium, grid planners named other obstacles to identifying the most useful transmission projects decades in advance.
MISO Senior Manager of Policy and Regulatory Planning RaeLynn Asah said load growth is the greatest uncertainty for today’s planning.
“It’s astronomical — I don’t know what word I want to use. It’s so large, and it’s so unknown,” Asah said.
Asah also said too-slow regulatory processes and seized-up supply chains are sources of anxiety. “They are a big deal. They keep me up at night,” she said.
However, Asah said there’s reason for hope. She said MISO is building a new planning model designed to be more responsive so MISO more easily can incorporate stakeholder suggestions and influence the model.
“I want to end on hope instead of the things we can’t do yet,” she said.
Lin said retaining a planning staff is becoming more challenging with stiff competition between planning organizations. “It’s a friendly competition among the ISOs/RTOs. And that’s great, but we always want to make sure our people are taken care of,” she said.
Climate Unknowns
MISO dedicated panels to climate change, a little-used phrase among the politically agnostic grid planner.
Argonne National Laboratory engineer Neal Mann said the lab’s projections of future weather patterns across a range of scenarios through midcentury and end of century seek to predict the more frequent heating and cooling degree days in addition to risks like flooding.
Mann said planners might want to “use their neighbors like a battery” to tap into their supply when they fall short.
The Electric Power Research Institute’s Parag Mitra said EPRI’s Climate Resilience and Adaptation Initiative (READi) collaborative model helps planners make decisions that will make the system more durable against ever more dangerous weather. Mitra said planners need to have a good understanding of how weather can affect assets.
Con Edison’s William Gunther said his utility is analyzing future multiday wind lulls and high midday solar output that is squirreled away in storage for later use. He said a Con Edison climate vulnerability study delved into how high substations need to be positioned due to sea level rise as well as the potential for undergrounding lines when temperatures are too hot for transformers to be in the open air.
Mitra said while there is a need for scenario-based planning that draws on probabilities of extreme events, it’s also valuable to analyze extreme events after the fact to pinpoint where conditions began a downward slide. He said demand response also can play a role in climate resilience.
But University of Michigan Professor Michael Craig said he discouraged planners from assigning climate disaster probabilities for planning purposes.
“When we think about climate change, I want to advise against using probabilities. Because we do not know … a meaningful probability of future climate scenarios,” Craig said. “Climate change is not a problem for 30 years from now; it’s increasing extremes today and tomorrow and the year after.”
Instead, Craig advocated stress testing solutions in modeling against wide-ranging degrees of extreme heat, extreme storms and extreme drought.
“It’s not like we hit 2050 and it turns over. Every year, those dice get loaded; every year you might have more extremes,” he explained.
New Analytics
Johns Hopkins University professor Benjamin Hobbs advised grid planners to adopt stochastic programming, which mulls multiple scenarios simultaneously and uses decision trees to come up with the most beneficial investments. He said MISO comes close to stochastic planning with its futures-based planning.
“The grid that you’re building needs to be nimble to be adaptive to economics, policy, climate,” Hobbs said.
Hobbs said a stochastic approach is useful for MISO, which contains states with and without carbon limits and renewable portfolio standards.
He said MISO could plug in variables like technological advancements, load growth, fuel costs, capital costs and carbon costs and limit potential solutions by constraints like siting limitations, emissions reduction standards and Kirchoff’s circuit laws.
Hobbs said he wasn’t suggesting planners could “naively” load up variables and expect a model to pinpoint the best grid solution. “What you’re getting from the model is suggestions,” he said. “All forecasts are wrong, so it’s important to consider a wide range of them.”
Iowa State University professor James McCalley made a case for adaptive co-optimized expansion planning, which shows the costs of grid expansions based on a specific future build (or a core) and the costs of adaptations to the original plan that may be necessary.
McCalley said the adaptive approach is a “cousin” of stochastic planning but not the same because the method is designed to show costs through time.
“I would make the case that both of these methods are useful tools in a planner’s toolbelt to understand the best way forward,” he said.
McCalley said adaptive co-optimized planning shouldn’t be a substitute for the PROMOD commitment and dispatch model, Siemens’ PSS®E Power Simulator or EPRI’s Electric Generation Expansion Analysis System. Rather, he said the method should be layered over them as an application to guide decisions.
McCalley said planners should continue to use their deterministic tools and introduce new, probabilistic analyses until they form a “single integrated method of doing the work.”
McCalley said he knows firsthand from his experience as a PG&E planner in the late ‘80s that deterministic planning leaves much to be desired. He recalled being grilled over planning practices in front of the California Public Utilities Commission.
“Probabilistic planning isn’t going to be a quantum leap for anyone. It’s going to be a journey, and we need to start now,” Mitra said.
AI Assistance
“Our grids are facing pressures like they’ve never faced before,” Microsoft’s Bilal Khursheed agreed, but offered AI as a means to lessen the tension.
Khursheed said the recent leaps in AI can better balance supply and demand in real time, improve resource utilization, assist in resource planning, better predict maintenance, provide the best insights to operators and speed the clean energy transition, among other things.
“These advancements aren’t incremental. They’re truly transformational in nature,” he said.
Khursheed said grid planners should think of AI as “the brain of modern grid flexibility,” the internet of things as “the eyes and ears of the grid” and the cloud as “the backbone of the ecosystem.” He also said planners first must consider the “balancing act” of leveraging the most they can from existing assets before deciding to physically expand the grid.
“It’s not just about building more. It’s about spending only when we absolutely have to,” he said.
Khursheed said AI’s sophistication can defer capacity investments by harnessing virtual power plants to provide flexible resource adequacy. He said Microsoft recently worked with a “large western European” transmission operator and found that it could cut “overcommitted fossil fuel resources” by 17 GW over the length of the pilot program through high-performance AI computing that helps operators make better use of cheaper, carbon-free resources.
The pilot saved the operator “millions of Euros,” Khursheed said, and the topology optimizer is set to be rolled out on a large scale in the footprint.
Khursheed said transmission operators are shifting from being “reactive” when facing storms and temperature extremes and using generative AI to figure out earlier which assets are likely to take a hit and what transfer capability stands to be the most helpful.
However, Khursheed said Microsoft is risk-averse and thus far is making sure AI is providing more accurate data sooner to “drive levels of productivity we’ve not seen before” but not running the grid autonomously.
“There’s still a human-in-the-loop component,” he said.
