ERCOT Technical Advisory Committee Briefs: May 22, 2024

AUSTIN, Texas — ERCOT stakeholders plumbed the depths of Robert’s Rules of Order and amended motions before endorsing a rule change May 22 that allows the grid operator to manually release ERCOT contingency reserve service (ECRS) from economically dispatched resources after repeated violations of the system power balance constraint. 

Following multiple failed attempts, the Technical Advisory Committee finally met the two-thirds threshold for approval by lowering the nodal protocol revision request’s (NPRR1224) offer floor from the originally proposed $1,000/MWh to $750/MWh. The measure passed 20-10, opposed by the consumer and retail segments over concerns of price increases. 

The change introduces a trigger that ERCOT can use to manually release ECRS from security-constrained economic dispatch (SCED)-dispatchable resources when the amount of the power balance violation is at least 40 MW for 10 consecutive minutes. With TAC’s modification, it would also require that energy offer curves for capacity assigned to ECRS be offered at the new floor. 

ERCOT staff and the Independent Market Monitor have been collaborating on the issue since late 2023 after ancillary service methodology discussions for this year at TAC and the Board of Directors. The board directed staff to review the processes used to compute the minimum quantities of ECRS and identify potential alternatives by May. 

The grid operator has been operating under a conservative posture since the 2022 summer. It has been procuring huge quantities of ancillary services to ensure it has enough operating reserves to account for intermittent solar and wind resources. 

However, that has increased costs in ERCOT’s energy-only market. The Monitor says ECRS, the newest ancillary product, created artificial supply shortages that produced “massive” inefficient market costs totaling about $12.5 billion last year through Nov. 27. (See ERCOT Board of Directors Briefs: Dec. 19, 2023.) 

The Monitor suggested the deployment trigger to avoid sequestering large quantities of ECRS out of SCED that it said caused the mechanism to perceive shortages that weren’t real and set energy prices much higher than their true marginal reliability value. It also proposed a re-evaluation of the ECRS procurement quantities and eliminating the $1,000/MWh offer floor. 

“Such a provision would retain a significant portion of the artificial shortage pricing that we documented in 2023, mitigating only those prices that exceeded $1,000/MWh,” the Monitor said in its comments. “While this may be in the economic interest of suppliers in the short term, setting prices that are not based on market fundamentals … will undermine the credibility of the ERCOT markets over the longer term.” 

Generation owners, led by Michele Richmond, executive director of Texas Competitive Power Advocates, and Lower Colorado River Authority’s Blake Holt and ENGIE’s Bob Helton, disputed the IMM’s valuation of ancillary service reserves. 

After first jokingly suggesting that the issue be placed on TAC’s combination ballot, Luminant’s Ned Bonskowski reminded members that ECRS was originally intended to be deployed with real-time co-optimization, which is still two years away. 

“It’s a tough problem where we’re trying to bridge two worlds,” he said. “We’ve got a lot of folks that are thinking about the extreme heat and scarcity that we had last summer and reacting to that, whereas I think the joint commenters looked at this and said, ‘Well, while we may not agree that the way ECRS is currently operated is the problem, we recognize that there is a concern, and so as a step towards compromise, let’s try to align whatever it is in NPRR2024.’” 

Bonskowski shared data that he said indicated releasing 500 MW of ECRS has a value “well above” the level recommended by the Monitor. He said the Protocol Revision Subcommittee’s (PRS) $1,000/MWh proposal falls “somewhere reasonably” in the middle. 

ERCOT’s Jeff Billo, director of operations planning, said the grid operator agrees with the concept of a floor and that it needs to be done correctly “regardless of the quantity.” 

“Then we can continue to work on what is the right methodology for determining the quantity,” he said. “We’re coming at this with different viewpoints on the offer floor.” 

TAC’s first attempt to endorse NPRR1224, as amended by the Monitor’s comments, fell flat at 10-18 with two abstentions. Its only support came from the consumer and retail segments. 

A second motion to endorse the change with the offer floor set at $500/MWh met the same fate by an identical vote. The retail segment was joined by the municipal segment. 

A third attempt at passage, this time as originally proposed by the PRS, also failed, at 15-11, with four abstentions. It was opposed by the consumer and retail segments. 

Finally, on its fourth attempt, TAC endorsed the measure. It must still be approved by the board and Texas Public Utility Commission, but it has been assigned urgent status so it can be effective this summer. 

TAC Endorses $1.2B Project

TAC endorsed the ERCOT Regional Planning Group’s recommended $1.2 billion project to rebuild 345-kV infrastructure in West Texas that will address thermal overloads and petroleum production load-growth issues in the region. 

The project easily cleared the $100 million threshold to be classified as a Tier 1 project, necessitating board approval. 

Assuming the rebuild is approved, Oncor, the transmission provider, will disconnect existing 345- and 138-kV transmission lines before rebuilding about 245 miles of new transmission lines and switches. It will also build a new substation and upgrade terminal equipment. 

The project was first identified in the grid operator’s 2021 Permian Basin Load Interconnection Study. Staff conducted a subsynchronous resonance (SSR) screening for the rebuild. They found no adverse SSR effects to the existing and planned generation resources and also determined the project did not cause new congestion within the area. 

The utility plans to complete the work by summer 2028. 

Plaque Honors Brad Jones

ERCOT has installed a plaque across from the board room memorializing former interim CEO Brad Jones, who died last year. 

Jones took over the grid operator’s reins in the wake of the disastrous and deadly February 2021 winter storm. He worked to raise public confidence in ERCOT and steady the ship before handing the helm to current CEO Pablo Vegas. (See Brad Jones, Former ERCOT, NYISO CEO, Dies at 60.) 

The plaque includes a quote from Teddy Roosevelt, Jones’ favorite president. It reads: “‘Far and away the best prize that life has to offer is the chance to work hard at work worth doing.’ I know the work we do here at ERCOT is, indeed, the best prize.”

Staff have also planted a tree in his memory outside ERCOT’s operations center in nearby Taylor. 

Theme of the Month

The meeting got off to a rocky start when ENGIE’s Helton attempted to submit a friendly amendment to the phrase of the month brought forward by American Electric Power’s Richard Ross. 

Ross, who provides a monthly theme for both ERCOT and SPP stakeholder meetings, called in to say May’s was “words matter.” 

“It’s been used quite well this week at SPP meetings,” Ross said. “I’m quite confident you guys can pull it off.” 

He resisted Helton’s suggestion to add “innovation” as a nod to the ERCOT Innovation Summit the day before. 

“I hate to be difficult, but it’s my phrase of the month,” Ross said as members erupted in laughter. 

2 Combo Ballots Pass

TAC members approved a separate combined ballot containing NPRR1198 and related changes to the Planning Guide (PGRR113) and Nodal Operating Guide (NOGRR258) that adds an extended action plan as a constraint-management plan suitable to managing congestion resolvable by SCED. 

Calpine, CenterPoint Energy, Jupiter Power and South Texas Electric Cooperative abstained from the unanimous vote, with Calpine’s Bryan Sams saying his company prefers SCED solutions. 

EDF Renewables’ Alexandra Miller, the NPRR’s sponsor, said her group included all input and requests to ensure transparency was consistent throughout the changes. 

“This is not something that is done outside of SCED, and it is a change to the system configuration. … Scalability is allowing transmission owners to operate and choose what to respond with,” she said. 

TAC unanimously endorsed its combo ballot and the withdrawal of a Planning Guide revision request (PGRR105) that would have added DC ties to the list of resources that must meet minimum deliverability conditions. ERCOT staff said the PGRR was contrary to a recent PUC decision and that it raises a policy issue that is best suited for the commission. 

The ballot also included the Real-time Co-optimization Battery Task Force’s recommended mitigated offer cap for all hydro resources and five NPRRs that, if approved by the ERCOT board, would: 

    • NPRR1218: update the state’s renewable energy credit trading program to clarify that it only applies to solar renewable energy. 
    • NPRR1220: modify the market’s restart process to require board and TAC approval and provide an alternative mechanism to board approval under certain circumstances. 
    • NPRR1222: elevate final approval of the “ERCOT Methodologies for Determining Minimum Ancillary Service Requirements” other binding document from the board to the PUC, consistent with commission discussions. 
    • NPRR1223: update a protocol form to require transmission and/or distribution service providers to provide contact information to ERCOT. 
    • NPRR1228: decrease the number of firm fuel supply service obligation periods awarded in a procurement from two to one.

FERC Upholds Tri-State Exit Fee Calculation Method

FERC on May 23 upheld the contract termination payment (CTP) rules for Tri-State Generation and Transmission Association it approved last year, though it modified some of its original order in response to requests for clarification (ER21-2818-002, et al.). 

The commission ordered Tri-State to implement a balance sheet approach for the CTP and a new transmission crediting approach that includes transmission-related debt. (See FERC Picks ‘Balance Sheet Approach’ Exit Fee for Tri-State Members.) 

Tri-State is a wholesale generation and transmission cooperative that serves members in Colorado, Nebraska, New Mexico and Wyoming with long-term, full-requirement wholesale electric service contracts. 

FERC’s preferred balanced approach was initially proposed by one of Tri-State’s members. The co-op argued for its preferred accounting methods on rehearing, but FERC declined to overhaul its December order. 

“We continue to find that the adopted BSA is consistent with principles of cost causation and with the purpose of an exit fee,” FERC said. “The presiding judge correctly explained that the BSA appropriately aligns costs and benefits to Tri-State members by declining to assign generation-related debt to Tri-State’s members located in the Eastern Interconnection, whose loads are supplied entirely through power purchase agreements.” 

FERC also continued to find the BSA’s treatment of PPAs is just and reasonable because it requires that members pay their pro rata share of those that are actually used to serve load. 

Tri-State argued that assigning the costs of dozens of PPAs to departing members would be unworkable, which did not persuade FERC. The commission said the co-op does not need to provide members with their exact share of PPA costs before they make a final decision on departure. 

FERC granted requests for clarification from Tri-State and Mountain Parks Electric on the amortization term for the transmission credit. It should be amortized over the remaining term for the depreciation rates in effect for the assets to which the debt payment relates, the commission said. 

It also clarified that the amortization term for the credit is determined based on the average remaining life of depreciable transmission plant base as determined by Tri-State’s most recent Form No. 1 filing at the time a member withdraws. 

The commission sustained the overall transmission crediting approach, finding the prepayment and back-crediting of transmission-related debt in the adopted BSA strikes a reasonable balance between ensuring the debt-related costs of Tri-State’s transmission assets are recovered through the CTP and ensuring the withdrawing member reaps the full benefit of these costs while minimizing cost shifts. 

“The payment of transmission-related debt as part of the CTP is intended to compensate Tri-State for the transmission-related debt it incurred to serve withdrawing members,” FERC said. “To prevent shifting costs onto remaining members, the withdrawing member must compensate Tri-State for this debt whether it uses Tri-State’s system or not.”

WCPSC Panelists: Forecasting Changes Needed to Address Uncertainty

VAIL, Colo. — “Uncertainty” was a recurring theme at the annual meeting of the Western Conference of Public Service Commissioners on May 19-22, where participants grappled with how to account for the growing number of unknowns in resource adequacy modeling in a future with less predictable weather patterns and unprecedented load growth.  

Some speakers at the meeting said the issue requires the electricity sector to fundamentally change its approach to load forecasting. 

“There’s a lot of climate and economic uncertainties,” Siva Gunda, vice chair at the California Energy Commission, said during a panel May 20. “Do we really understand the climate data, and are we incorporating it into the forecast? Most of our work has been historically given — historic insights, historic weather patterns; obviously that’s not true anymore.” 

The theme of uncertainty dominated conversations about RA, as industry experts shared both a fear of how changing conditions will affect the grid and an inspiration to address the unknown.  

“The operational conditions on the system have become a challenge, and the need to harness the collective integration, diversity and power of the grid has never been more true,” said Sarah Edmonds, CEO of Western Power Pool. “Several years ago, utilities … observed that we are, for lots of reasons, headed toward a real reliability pinch in the West.”  

Load growth was essentially flat for over a decade compared with today’s “astronomical” load growth projections stemming from new data centers, widespread electrification, and other trends in technology, policy and economics, said FERC Commissioner Mark Christie.  

These “macro drivers” should be considered in modeling and forecasting, rather than relying solely on historical data, according to Jeremy Hargreaves, principal at Evolved Energy Research. Other macro drivers include state emissions targets, decarbonization and electrification policies, artificial intelligence sector growth, and crypto markets.  

“The question is how to proactively plan in the face of uncertainty. We want to be finding these no-regrets actions that we can take that are informed by these macro drivers, recognizing there’s a lot of uncertainty in how these will play out,” Hargreaves said. “We need more complex modeling approaches to try and estimate what kind of impacts they’ll have.”  

Gunda emphasized the importance of adequate forecasting to address uncertainty and maintain reliability.  

“Forecasting has a direct implication on affordability; it has a direct implication on reliability; it has direct implications on economic and industrial processes. And so, what we’re doing right or wrong will directly affect the entire system,” Gunda said.  

Forecasting should evolve to keep up with changing conditions and uncertainty, and Hargreaves and other industry analysts suggested supporting the grid with bottom-up forecasting and end-use forecasting, which looks at individual customer load geographically.  

“My argument is that our historical approach to planning is not going to do,” said Ry Horsey, researcher and software engineer at National Renewable Energy Laboratory. “Forecasts should inform planning and decision-making.”  

Evolved Energy Research has looked at a variety of different sectors and developed a load-growth taxonomy that reflects different loads and how they impact people over time, and Hargreaves suggested more widespread implementation of this model in forecasting.  

Robert Kenney, president of Xcel Energy’s Colorado division, summed up both the fear of uncertainty and the actions being taken to address it.  

“I don’t think there’s any disagreement that we’re retiring resources more quickly … we have load showing up in ways that we haven’t seen in 20 years,” Kenney said. “We should be freaked out, but only to the extent that it drives creativity and action.”

Overheard at the 76th Annual NECPUC Symposium

CARROLL, N.H. — Angst over looming load growth, cost increases and reliability headaches headlined the 76th annual New England Conference of Public Utilities Commissioners (NECPUC) Symposium, held May 20-21 at the Mount Washington Hotel. 

“I think it is a laudable goal to want to get rid of any greenhouse gas-emitting source, but we’re going to have to do this at pace,” said Charles Dickerson, CEO of the Northeast Power Coordinating Council. He said that as policymakers push for “100% reliable, 100% renewable and 100% really cheap [power], I just don’t think those three [aspects] can exist in one space at one time.” 

Dickerson called on regulators to work to encourage innovation and be “a little less rigid” around cost recovery for utilities experimenting with new solutions. 

“If we take the same approach to regulation that we’ve taken over the past 100 years, it’s probably going to take us 100 years to solve this,” Dickerson said, adding that regulators should try to approach the looming challenges with “a little bit more risk tolerance and a lot more creativity.” 

Vineyard Offshore CEO Alicia Barton pushed back with a more optimistic tone. 

“Respectfully, I do disagree — actually pretty strongly — that we can’t do all three,” said Barton, former CEO of the New York State Energy Research and Development Authority. She emphasized that changes to the power purchase agreement model, including tweaks to contract lengths and inflation-adjustment mechanisms, could help bring costs down. 

“You can actually get better costs if you leverage some of these choices,” Barton said. 

Richard Levitan of Levitan & Associates recommended that public utility commissions “embrace principles of transparency, honesty and realism” when weighing competing priorities. 

“I don’t think in the pursuit of clean, reliable and affordable [that] there are easy tradeoffs,” Levitan said. “There is no one unassailable answer; there’s no quick solution; but constructive debate with prominent stakeholders — possibly through the ISO, but at the state level too — should inspire awareness, and I think that’s a laudable goal.” 

Coping with Increasing Demand

ISO-NE projects that load growth will rapidly accelerate in the coming decades, doubling current peak load levels by 2050. The RTO estimates that the transmission upgrades required to meet this peak will cost in the range of $19 billion to $26 billion. (See ISO-NE Analysis Shows Benefits of Shifting OSW Interconnection Points.) 

These upgrades will come on top of increasing costs associated with upgrading and climate-proofing distribution networks and accumulating state PPAs. (See How Sea Level Rise, Coastal Flooding Threaten Boston’s Grid.) 

One way to limit costs would be to maximize the potential of high-performance conductors and grid-enhancing technologies (GETs) like dynamic line ratings, advanced-power flow control and topology optimization, said Rob Gramlich, president of Grid Strategies. 

Gramlich noted that the deployment of GETs in the U.S. has lagged behind other countries. 

“You just have to wonder whether the cost-of-service regulatory model — which rewards large capital investments — is a disincentive for getting senior management at utilities to really deploy these things,” Gramlich said. “I think we’re at the place nationally with GETs where there’s a need for some independent expert who has access to all the information to identify where the right technology could apply.” 

Tiffany Menhorn, principal at the Menhorn Group, said GETs often can provide ancillary grid resilience benefits and give utilities “eyes on your line like never … before.”

Along with better real-time awareness, predictive analytics could provide significant insights into asset health and help to identify anomalies, Menhorn added. 

Speakers also highlighted retail demand response as an area for improvement that could significantly reduce the overall costs associated with the clean energy transition. 

ISO-NE CEO Gordon van Welie said activating DR at the retail level remains “a work in progress.” 

In February, NECPUC launched a yearlong working group to look at how retail DR can help address peak load and resource adequacy challenges. 

“What I hope for is a standardized approach to doing demand response in the region,” van Welie said, adding that deploying automation, sending the right price signals and incorporating retail DR into the wholesale markets will be essential. As winter risks increase, longer-duration DR that can extend over multiday periods will become increasingly valuable. “That’s a much more complicated type of demand response, and I think it’s an opportunity for us to innovate as a region.” 

The Role of Natural Gas

Several of the speakers presented significantly different visions for the role natural gas and gas pipelines will play in the coming decades. 

“I hope that states don’t get away from … everything that we’re doing to ensure the safety and reliability of that infrastructure,” said Georgia Public Service Commissioner Tricia Pridemore, who is also first vice president of the National Association of Regulatory Utility Commissioners. 

“I’m a pro-gas commissioner,” Pridemore said. She noted a report by the National Petroleum Council that found that “the pipeline infrastructure is going to be with us for a long time,” arguing that alternative fuels like hydrogen and renewable natural gas (RNG) will rely on the gas system as states decarbonize. 

Marc Brown of the Consumer Energy Alliance, an advocacy group whose members include a wide range of industrial end users and fossil fuel companies, called natural gas “part of the solution” and argued that the most significant decarbonization gains over the past two decades have come from the proliferation of natural gas. 

He said environmental progress and decarbonization “is going to take people accepting the fact that natural gas is going to continue to play an important role in affordability, reliability and emissions reductions in the near- and midterm future.” 

In contrast, Emily Green, senior attorney at the Conservation Law Foundation, said states should engage in long-term planning efforts to transition off fossil fuels, including natural gas. She highlighted the significant warming effects of methane leaks from the gas system, which are typically underestimated by state and national greenhouse gas inventories. 

“We’re going to be paying for today’s investments in gas for decades to come, both in terms of emissions and ratepayer impacts,” Green said. “It’s low-income consumers that are going to be left holding the bag.” 

Green also called on regulators “to be very wary of utilities looking to maintain or even upgrade pipelines on the future promise of biomethane or hydrogen.” 

In the Massachusetts Department of Public Utilities’ final rule on its multiyear “Future of Gas” investigation, it found that efforts to blend hydrogen and RNG into the gas network should not be funded through the general rate base (20-80-B). 

“The department is uncertain about the viability of hybrid heating and hydrogen technologies and their potential as economical long-term solutions for ratepayers,” the DPU wrote, adding that “RNG and the use of hydrogen as a fuel are emerging technologies that have not yet been proven to lead to a net reduction in GHG emissions.”

FERC Responds to Mystic Agreement Rehearing Request

FERC has denied a rehearing request and partly adopted a clarification request by Constellation Energy related to a challenge to the fixed costs associated with the Mystic cost-of-service agreement (COSA) (ER18-1639-028). 

Initially signed in 2018, Mystic’s COSA between Constellation and ISO-NE delayed the retirement of the Mystic Generating Station by two years to help provide fuel security to the region. The agreement is set to expire — and Mystic to retire — at the end of May. 

As part of the COSA, Constellation is required to submit annual informational filings related to the costs of the agreement. Relevant stakeholders are allowed to request more information and ultimately challenge the filings with FERC.  

The May 23 FERC ruling stems from an October 2022 series of challenges by a group of municipal utilities to an informational filing submitted that year.  

In December 2023, FERC granted several of the municipal utilities’ challenges, determining “that the challenges raised issues of material fact that could not be resolved on the record before the commission, and thus established hearing and settlement judge procedures.” 

In January 2024, Constellation requested rehearing on three of the order’s rulings and clarification on two rulings — while also requesting rehearing on the latter two rulings if not granted the clarifications. 

“The relief sought herein is aimed at avoiding unnecessary litigation in a case that has seen too much already,” the company wrote. 

In its ruling May 23, FERC dismissed the rehearing requests on the basis that the challenge order was not a final decision and therefore not subject to rehearing. 

FERC did grant Constellation’s clarification request regarding projected 2023 capital expenditures at the Everett LNG import facility, which also is owned by Constellation and provides the fuel for Mystic via a fuel supply agreement.  

A 2022 settlement agreement among Constellation, the New England states and ISO-NE “resulted in the Mystic Agreement no longer providing recovery for any Everett 2023 [reliability-must-run capital expenditures],” FERC wrote.  

“Accordingly, we grant Mystic’s requested clarification and determine that there is nothing further to litigate” regarding this aspect of the informational filing, FERC ruled.  

Meanwhile, FERC affirmed its 2023 ruling to “set for hearing and settlement judge procedures” the three other formal challenges to the informational filings, which relate to the calculations of Mystic and Everett’s rate bases prior to the agreement.

PJM Reaches Milestone on Clearing Interconnection Queue Backlog

PJM on May 20 announced that it had completed the first phase of studies for 306 generation interconnection requests sorted into the first cycle in the transition to its new interconnection process, a cluster-based study approach intended to reduce how long it takes the RTO to bring generators online. 

“This is another critical milestone for PJM’s widely supported interconnection process reform,” said Aftab Khan, executive vice president of operations, planning and security. “New service requests for generation resources are moving through our process as designed and promised, with more than 200,000 MW of projects to be studied over the next two years to help states advance their energy policy goals.” 

Developers with projects in Transition Cycle 1 (TC1) will have 30 days to review the system impact studies and decide whether to move forward with their projects to the facility study phase. PJM said those that complete the process will be ready for construction by mid-2025. (See PJM Initiates Transitional Interconnection Queue.) 

Another 306 projects expected to require minimal network upgrades are being studied through an Expedited Process “fast lane” that is expected to yield final interconnection service agreements (ISAs) throughout this year. PJM also plans to initiate Transition Cycle 2 on June 20, with a likely application deadline by Dec. 16. 

PJM said about 72 GW are expected to clear the queue by mid-2025 and 230 GW over the next three years, more than 90% of which is renewable energy or storage. 

The cluster-based approach groups projects together on a first-ready, first-served approach to identify any grid upgrades and assign costs. It also includes increasingly large readiness deposits to be made throughout the study process, with the aim of discouraging speculative or uncertain projects from taking focus away from others. PJM said 118 projects have dropped out of the queue or failed to post deposits, out of 734 eligible. (See FERC Approves PJM Plan to Speed Interconnection Queue.) 

Environmental organizations said the milestone is a welcome first step but that more change is needed. 

“PJM worries there’s not enough new power coming online, but it’s still only approving projects proposed four to six years ago,” said Tom Rutigliano, of the Natural Resources Defense Council. “This is a step forward, but PJM’s current process is not enough to get these new clean energy projects connected to the grid as quickly as they’re needed.” 

Christine Powell, deputy managing attorney at Earthjustice, said the amount of time it has taken for PJM to get to this stage has already resulted in projects stalling or withdrawing from the queue. “While PJM’s shift to a cluster study process is a positive development for the hundreds of clean energy projects waiting to interconnect to the power grid, PJM continues to lag behind other RTOs,” she said. 

Katie Siegner of RMI pointed to a study released in February that found that incorporating grid-enhancing technologies (GETs) into how PJM conducts transmission planning could optimize the use of existing infrastructure to reduce upgrades needed for new projects and speed interconnection studies. The study estimated that about $1 billion in annual production costs could be avoided through 2033 by expanding use of GETs. (See RMI Report: GETs Could Speed Renewable Development, Save Consumers Billions.) 

PJM’s “clearest opportunity for improvement is bringing its interconnection process into compliance with Order 2023, particularly through serious consideration of alternative transmission technologies that could provide faster and cheaper network upgrade alternatives,” Siegner said. “The fact that no grid-enhancing technologies have been identified or used as network upgrades to date suggests PJM has more work to do in incorporating these fast, flexible transmission tools into its study methodologies.” 

PJM spokesperson Jeff Shields told RTO Insider the RTO allows and welcomes GETs as components of proposals for its Regional Transmission Expansion Plan and laid out how it will fully comply with Order 2023’s requirements around their facilitation in its May 16 compliance filing (ER24-2045). 

“All of the enumerated [GETs] already are considered and studied as necessary, if merit exists in the use of such technologies, in the course of interconnection studies in the PJM region,” Shields said. “This incorporation of new and emerging technology is consistent with the objectives of the final rule, which requires transmission providers to evaluate certain GETs in each and every one of its interconnection studies.” 

Shields said PJM agrees there is more progress to be made in improving generator interconnection and development, both at the RTO and removing external obstacles. “We are working with stakeholders within the PJM stakeholder process, as well as entities outside of the PJM membership, to accomplish this.”

FERC Directs ISO-NE to Submit Another Order 2222 Compliance Filing

Responding to a rehearing request by Advanced Energy United over FERC’s partial acceptance of ISO-NE’s third Order 2222 compliance filing, FERC has directed ISO-NE to submit an additional filing to specify its metering and telemetry practices for distributed energy resource aggregations (DERAs) (ER22-983-006). 

Order 2222, which requires RTOs to update their tariffs to enable DERAs to participate in wholesale markets, has led to a long series of compliance filings and rehearing requests related to ISO-NE’s compliance.  

FERC accepted ISO-NE’s fifth compliance filing April 11, subject to further compliance. (See Still More Work for ISO-NE on Order 2222 Compliance.) 

On May 23, FERC issued an order on rehearing responding to Advanced Energy United’s challenge of ISO-NE’s third compliance filing, which FERC accepted Nov. 2, 2023. (See FERC Accepts ISO-NE Order 2222 Compliance Filing.) 

“We sustain three of the four findings AEU [Advanced Energy United] challenges,” FERC ruled.  

Responding to the trade association’s argument that ISO-NE’s three metering options for DERAs — “retail delivery point metering, submetering with reconstitution and parallel metering” — are unnecessarily prohibitive, FERC affirmed its finding that these options “do not pose an unnecessary or undue barrier to individual DERs joining an aggregation.” 

FERC upheld its acceptance of ISO-NE’s proposal to apply the requirements of the “binary storage facility” and “continuous storage facility” participation models for DERAs to provide withdrawal service. FERC also continued to find that the ISO-NE properly explained the steps it took to “avoid imposing unnecessarily burdensome costs on DER aggregators and individual resources in DERAs.” 

However, FERC set aside its prior ruling that ISO-NE adequately described its metering requirements for DERAs.  

“Specifically, we set aside our finding that, for those DERAs containing behind-the-meter DERs, ISO-NE’s tariff includes a basic description of the metering practices for DERAs with references to specific documents that contain further technical details for metering and telemetry practices,” FERC wrote.  

“ISO-NE’s basic description of its metering practices for DERAs is incomplete because its tariff does not include submetering requirements for DERAs participating as submetered Alternative Technology Regulation Resources,” FERC added. 

FERC directed ISO-NE to submit an additional compliance filing to specify these submetering requirements. FERC also set aside its ruling that ISO-NE’s proposal to extend “existing requirements for Alternative Technology Regulation Resources to DERAs” is just and reasonable, writing that it will reassess these requirements after the RTO submits its additional compliance filing.  

Caitlin Marquis of Advanced Energy United said FERC’s directive “sends ISO back to the table to resolve one metering barrier for DERs seeking to provide regulation service, which is welcome and important.” 

“However, as New England and the rest of the country face rising demand, rising electricity prices and reliability threats, much work remains to ensure the region is taking full advantage of DERs,” Marquis added. 

Commissioner Mark Christie concurred with the parts of the order that accepted ISO-NE’s filing and dissented “to the rest.” 

Christie decried Order 2222’s “seemingly never-ending and avoidable rounds of compliance filings” and called the compliance saga a waste of time and money.

FERC to SPP: Show More Work on PRM Determination

FERC on May 23 found SPP’s tariff revisions laying out how it determines its planning reserve margin (PRM) methodology only partly met the commission’s order on rehearing and directed an additional compliance filing within 30 days (ER24-1221). 

The commission said SPP complied with its directive to include a timeline for making changes to the PRM before a planning year in its tariff. But it also said the RTO failed to include further information on how it uses its loss-of-load expectation studies to determine the PRM. 

FERC accepted SPP’s tariff revisions effective April 10, subject to further compliance. 

The commission rejected protests from the grid operator’s members that SPP provide three years’ notice before increasing the PRM and that it be prohibited from adopting near-term increases without demonstrating that the market has capacity surplus available for purchase. The commission found both arguments to be outside the compliance proceeding’s scope, saying its directive only required the timeline for making PRM changes. 

The RTO said it will perform an LOLE study at least biennially to determine whether a PRM change is needed and post the results. Staff will then provide a recommendation for any changes, with the Board of Directors and state regulators approving the change. The tariff revisions place additional restrictions on any approved PRM that exceeds the current value or the value identified in the final LOLE results by 1% or more; any PRM increase would be implemented for the planning year, beginning at least one year after approval. 

SPP’s board in 2022 approved changing the PRM to 15% from 12% over opposition from stakeholders advocating a three-year phase-in. Load-responsible entities unable to meet the requirement can incur financial penalties from the RTO. (See SPP Board, Regulators Side with Staff over Reserve Margin.) 

FERC last year rejected a complaint by SPP members seeking to overturn the decision. In a 3-1 vote, the commission ruled that American Electric Power, Oklahoma Gas and Electric, and Xcel Energy failed to show SPP’s PRM process was unjust, unreasonable or unduly discriminatory because the figure itself was not included in its tariff. (See FERC Rejects Protest of SPP PRM Increase.) 

AEP, OG&E and Xcel filed a rehearing request with FERC, but the commission took no action on it. They then filed a petition for review with the 8th U.S. Circuit Court of Appeals in July 2023; that proceeding has been held in abeyance pending SPP’s compliance filing following a successful FERC motion (23-2734). 

FERC found in September 2023 that SPP’s proposal failed to “adequately” explain how it would account for the LOLE study’s results or any additional considerations when determining the PRM, and that the tariff did not adequately explain the timeline for the RTO’s PRM reviews (EL23-40-001). FERC ordered a compliance filing within 60 days, but SPP and the protesting companies jointly requested an extension to February, which the commission granted.

ERCOT Projects 97-GW Peak Demand by 2034

[EDITOR’S NOTE: This story has been updated to reflect ERCOT’s new unofficial peak demand record for the month of May, set May 27. The previously reported mark for the day was 73.75 GW.]

ERCOT’s latest capacity, demand and reserves (CDR) report projects summer peak demand will increase to more than 97 GW by 2034, assuming normal weather conditions. 

However, the weather has been anything but normal recently in Texas. ERCOT is coming off the second-hottest summer in state history, and it just set an unofficial peak demand record for May (77.13 GW) that exceeds the grid operator’s all-time peak from 2018 (73.47 GW).

The heat index hit 113 degrees Fahrenheit in Austin on May 25 and has already hit triple digits in Houston, where the low temperature dropped to only 80 degrees on May 21. That is about a month and a half ahead of normal, according to a local forecaster. 

The National Oceanic and Atmospheric Administration (NOAA) has predicted an “above-average” hurricane season this year, with between 17 and 25 named storms. It says “extraordinarily high, record-warm water temperatures” in the Atlantic Ocean, linked to climate change, are energizing the waters and fueling storm development.  

NOAA said another factor influencing this year’s hurricane season is La Niña, a climate pattern that cools surface ocean temperatures and lessens wind speeds, allowing more storms to develop. 

The CDR report forecasts peak demand of 83.29 GW this summer, assuming normal weather conditions. Demand is expected to exceed 84 GW in 2026, 86 GW in 2028 and 90 GW in 2030, according to the report. 

Energy consultant and Stoic Energy principal Doug Lewin doesn’t think that is enough. He says ERCOT still doesn’t factor climate change into its projections, and he noted the ISO’s current record for peak demand is 85.46 GW, registered last August.  

“They only expected 73 GW this month and we’ve already passed that. Had this heat hit outside a holiday weekend, we’d likely be around 80 GW,” he said on X, the social media platform formerly known as Twitter. 

ERCOT says its load forecasts are based on normal weather conditions and determined by the methodologies posted to its website. Staff forecasts scenarios through 2033 using a model with historical weather years. 

The CDR report is designed to provide forecasted planning reserve margins (PRMs) for ERCOT’s summer (June-September) and winter (December-February) peak-load seasons. The ISO says it is not intended to characterize the risk of scarcity conditions from a real-time operations perspective. It defines the PRM as the percentage of capacity above firm demand that is available to cover uncertainty in future demand, generator availability and new resource supply. 

ERCOT’s operational capacity exceeds 100 GW next year but increases to only 101.50 GW by 2033. However, the CDR report indicates the grid operator expects 30 GW of planned capacity by that same time, with solar resources accounting for 28 GW.

BOEM FEIS Cites ‘Major’ Impact from NJ OSW Project

The Bureau of Ocean Energy Management released its final environmental impact statement (FEIS) May 23 that concludes that New Jersey’s foremost offshore wind project, Atlantic Shores, would have a “major” impact on commercial and for-hire recreational fishing, the view from the shore and on-ship traffic. 

The 560-page study found that the 200-turbine, 1,510-MW project would impact the commercial and recreational fishing sector through a range of activities, including anchoring, cable emplacement, noise, port use and structure presence. At about 10 miles from the shore, Atlantic Shores is the closest OSW project in development to the land in New Jersey. 

But the FEIS also concludes the area would suffer a major impact even if the project were not constructed. Those impacts would stem from factors including fishery management measures taken to ensure that the volume of fish caught is sustainable; the impact of climate change from ocean warming, sea level rise and ocean acidification; and non-OSW construction on land. 

Likewise, the study found that although the project would have a major scenic impact on the area — on the open ocean, seascape, and landscape character and views — the coast would suffer a strong scenic impact regardless because of onshore development and construction activities, offshore vessel traffic and the effects of other OSW projects. 

And the agency found that the impact of the project on most of the other 19 categories studied — including recreation and tourism, land use and costal infrastructure, water and air quality, and a variety of animal species — would be moderate or minor.  

BOEM compiles EIS reports to assess the potential impacts from an OSW project on physical, biological, socioeconomic and cultural resources. The final report informs BOEM’s decision on whether to approve, approve with modifications or disapprove the project’s Construction and Operations Plan (COP), and the FEIS may also be used by other agencies in evaluating the project. 

The FEIS evaluates the impact on the area if the project does not go ahead and if the project goes ahead as planned. The agency also looks at the impact if the project were reshaped or adjusted to try to mitigate any effects, such as by reducing the number of turbines or their position in the lease area. But any such adjustments did not generally reduce the impacts of Atlantic Shores that BOEM assessed as “major.” 

In response to the release of the FEIS, Atlantic Shores said it “remains dedicated to responsible development [and] environmental stewardship.” 

“We are encouraged to see forward progress and getting another step closer to delivering New Jersey’s first offshore wind projects,” said CEO Joris Veldhoven. “We appreciate BOEM’s thorough environmental evaluation and recognize the significance of this milestone.” 

Tourism, Whale Impact

Atlantic Shores, a 50/50 joint venture between EDF-RE Offshore Development and Shell New Energies US, was one of two projects — along with Danish developer Ørsted’s Ocean Wind 2 — that the New Jersey Board of Public Utilities approved in its second solicitation in 2021. That followed the agency’s approval in 2019 of Ørsted’s Ocean Wind 1 project. (See NJ Awards Two Offshore Wind Projects.) 

Ørsted has abandoned its two projects, saying they were no longer feasible. 

New Jersey approved two more projects in its third solicitation, and the combined total of those two and Atlantic Shores would, if completed, account for slightly less than half the state goal of 11 GW of OSW capacity by 2040. The state in April opened a fourth solicitation. (See New Jersey Opens 4th Offshore Wind Solicitation.) 

Critics of the projects are concerned about the impact on the commercial fishing and tourism sectors and on the quality of life to local homeowners, especially from an impaired view of the sea. 

The study also found the project would have only a minor impact on the tourism industry. 

Navigation and vessel traffic in the area would suffer only a moderate impact if Atlantic Shores were not built, but a major impact if it were because of “increased vessel traffic in and near the project area and on the approach to ports used,” according to the report. Traffic would especially increase during the construction period, and the impacts would include “changes to navigational patterns and to the effectiveness of marine radar and other navigation tools” that could result in “delays within or approaching ports, increased navigational complexity [and] detours to offshore travel or port approaches,” the study says. 

The study found the project would have only a moderate impact on most mammals but would have a major impact on the North Atlantic right whale, which is an endangered species. That assessment stemmed from the fact that “impacts on individual NARWs could have severe population-level effects and compromise the viability of the species due to their low population numbers and continued state of decline,” the report said. 

Opponents of OSW projects regularly cite a series of whale deaths on the Jersey Shore as potentially caused by preliminary OSW activities. But construction has yet to begin on any project in the state, and federal and state investigators have found no link between the deaths and OSW activities, saying they are most likely caused by vessels hitting the whales.
