Treasury Department Releases Guidance on 45X Credit for Manufacturing

The U.S. Department of Treasury and the IRS on Thursday released proposed guidance on the 45X Advanced Manufacturing Production Credit, which is available to producers of wind and solar components, inverters, battery components and critical minerals. 

The tax credit is part of the Inflation Reduction Act, which the department said already is creating manufacturing jobs. 

“These new investments across industries and throughout clean energy supply chains are creating good-paying jobs and driving down the cost of clean energy for Americans,” Secretary of the Treasury Janet Yellen said in a statement. “New manufacturing investments are disproportionately going to communities that have lacked opportunity and are key to increasing long-run growth and the productivity of our economy.” 

Treasury released a notice of proposed rulemaking (NOPR) on the 45X tax credit, which proposes clarifying definitions and confirms credit amounts for the components it covers. It proposes definitions for key terms meant to incentivize domestic production and clarifies the circumstances under which the credit can be claimed. 

The NOPR includes safeguards against fraud, waste and abuse, including ways to avoid double-credits for the same component, crediting of activities that add no value and extraordinary circumstances in which clean energy components are produced but never used productively. 

The tax credits will be in full effect through the end of this decade and, starting for components sold in 2030, they will ramp down to 75%, then 50% in 2031, 25% in 2032 and be phased out entirely in 2033. Only the 50 applicable minerals will be eligible for the 45X credit after 2032. 

Solar energy components include modules, photovoltaic cells, photovoltaic wafers, solar grade polysilicon, torque tubes, structural fasteners and polymeric backsheets. Modules or photovoltaic cells would get a credit based on their nameplate capacity in direct current watts under standard testing conditions. 

Wind energy components include blades, nacelles, towers, offshore wind foundations and related offshore wind vessels. Eligible ships would be those purpose-built or retrofitted for installing offshore wind turbines, while wind tower components would get credits based on the capacity of the completed turbines. 

Both utility-scale and distributed-energy-scale inverters would be eligible for the tax credits, the NOPR said. Eligible battery components include electrode active materials, battery cells and battery modules. 

Treasury also released new analysis from its economists using data from the Massachusetts Institute of Technology and the Rhodium Group showing how the IRA already has accelerated clean energy manufacturing.  

Since the bill was passed, 76% of investment dollars in clean energy manufacturing have gone to counties with average weekly wages below the U.S. average; 66% are in counties with college graduation rates below the U.S. aggregate rate; 54% of investment went to counties with lower employment levels than average; and 69% went to counties with incomes below the median. 

The American Clean Power Association welcomed the NOPR, noting that over the past 16 months the clean energy sector has announced 112 new manufacturing facilities that will employ more than 41,000 workers. 

“Today’s guidance is a critical next step for U.S. manufacturers as they work to make announced facilities a reality,” said ACP Chief Advocacy Officer JC Sandberg. “By creating and expanding supply chains to make clean energy technologies here at home, we will strengthen America’s energy security, create good-paying American jobs and boost the nation’s economy.” 

American Council on Renewable Energy Executive Vice President José Zayas also welcomed the new guidance, which he said would help clean energy manufacturing to continue growing. 

“The inclusion of key components, including emerging battery technologies and offshore wind vessels, in addition to prior guidance unlocking the direct pay option for the 45X credit, provides needed clarity for our sector as we work toward achieving the enhanced domestic manufacturing base we need to meet the growing demand for clean and renewable power, secure our grid, lower costs and maximize American competitiveness,” Zayas said. 

Advanced Energy United also welcomed the guidance, while highlighting that it includes recycled content and allows for innovative technologies to qualify. 

“By permitting recycled content, Treasury has further incentivized the development of a circular clean energy supply chain, something fossil fuels can never achieve, while also helping make imported content into American-made resources,” said AEU Managing Director Harry Godfrey. “By allowing new and innovative technologies, like permitting DC-optimized inverter systems to qualify as microinverters, Treasury is ensuring that this policy encourages, rather than stifles, innovation in this dynamic industry.”

NYISO BIC Stakeholders OK Modeling, Market Design

NYISO on Dec. 13 presented its market design for dynamic reserves to the Business Issues Committee, which endorsed the concepts on the condition that issues including cost allocation and congestion revenues be discussed next year, as the ISO tests the new design.

The ISO’s current operating reserve requirements are static, based on the largest single source contingency.

A NYISO white paper in December 2021 proposed that the grid operator explore dynamically scheduling reserves, saying it was feasible to set reserve requirements based on the single largest contingency systemwide and using available transmission headroom. The paper said determining reserve requirements based on grid conditions and topology would better align market outcomes with system conditions by, for example, shifting reserve procurements to lower-cost regions as permitted by transmission capacity. (See NYISO Outlines Timelines for 2023 Projects.)

The proposed design is composed of five concepts, including use of individual generator shift factors — the ability of a generator to relieve transmission constraints — to meet locational reserve needs, monitoring about 20 key transmission interfaces and considering the day-ahead market (DAM) forecast load.

The ISO’s static locational reserve requirements assume the transmission system is fully scheduled.

NYISO’s presentation also discussed how various market elements like thunderstorm alerts, scarcity pricing and the correlated loss of multiple generators might be impacted by the reserve market changes.

NYISO plans to prototype the proposed design and finalize tariff language next year, with the expectation that the concepts will be deployed in 2026.

The ISO said elements such as forecast reserve shadow prices and DAM congestion rents will not be included in prototyping but will undergo review with stakeholders next year.

BIC stakeholders commended the ISO’s efforts in establishing a dynamic reserve market design. David Clarke, director of wholesale market policy at the Long Island Power Authority, said “this is really good and really innovative work.”

Pallas LeeVanSchaick, vice president at the ISO’s Market Monitoring Unit, Potomac Economics, similarly praised the ISO’s work. “The scheduling and optimization components are truly innovative and are really going to be helpful to the market in terms of ensuring that the market design is adaptable to changing conditions,” he said.

LCR Optimizer Market Design

The BIC also voted to approve changes to make the locational capacity requirements (LCR) optimizer more transparent and produce more stable results.

The LCR optimizer, implemented in 2019, establishes the least-cost LCRs for several downstate NYISO capacity zones, including New York City and Long Island.

The ISO proposed three changes. First, it suggests determining least cost options by adding up the incremental costs of individual units, which it calls the investment cost — or “area under the curve” — as the optimizer’s objective function. The ISO currently seeks to minimize total procurement cost, in which every megawatt of capacity is priced like the last megawatt.

The ISO’s second recommendation calls for determining net CONE curves without the level of excess (LOE) adder to simplify the optimizer’s formulation.

The final recommendation is to develop additional energy and ancillary services revenue modeling test points in the current demand curve reset project. While NYISO acknowledges that this aspect of the optimizer’s formulation has not been tested, it committed to providing updates on these testing efforts next year.

Michael Mager, a partner at Couch White, representing Multiple Intervenors, a group of large industrial, commercial and institutional energy consumers, asked about the timeline for initial results from the new testing. NYISO staff responded that these results could be expected in February or March.

Assuming the proposed changes improve the LCR optimizer’s results, the ISO aims to seek approval from the Management Committee in mid-2024 and expects these improvements will be used to determine zonal LCRs applicable for the 2025/26 capability year.

Capacity Accreditation Modeling

The BIC voted to recommend that the MC approve proposed tariff revisions presented by NYISO, which aim to improve capacity accreditation modeling by more accurately capturing attributes like natural gas constraints and correlated derates, as well as address issues raised by Potomac Economics. (See NYISO MMU Calls for Improved Shortage Pricing, More Capacity Zones.)

Resource adequacy analyses indicate that current modeling misrepresents the marginal reliability contributions of some resources and fails to capture metrics not represented in installed reserve margins and LCRs, resulting in inaccurate capacity accreditation factors and capacity accreditation resource class (CARC) calculations for certain resources. (See NYISO Previews Capacity Accreditation Modeling Work.)

The revisions seek to align the compensation capacity resources receive with their performance, availability and marginal contribution to reliability needs.

To address gas constraints, the ISO developed a process allowing gas units to make a “fuel characteristic election” on Aug. 1 prior to the start of the next capability year. This is based on the unit’s ability to partly or fully meet requirements for entry into a firm fuel CARC. Units seeking to be firm on gas must have a transportation contract covering the megawatts elected, with a contract path from a liquid receipt point to the burner tip during December, January and February.

Units with on-site fuel are required to have enough to operate at max output for 16 hours a day for six days in those same winter months. The first fuel characteristic election must be made by Aug. 1, 2024, and units failing to substantiate their level of firm supply may face a shortfall penalty.

Howard Fromer, representing Bayonne Energy Center, asked about the impact of these revisions on generation using hydrogen as a fuel source. NYISO staff clarified that these new requirements apply to any unit burning on-site fuel or fuel being delivered through a pipeline.

For correlated derates, NYISO proposes addressing issues identified in the MMU’s annual State of the Market report by applying ambient water-related deratings to units with once-through water cooling, adjusting for humidity in units with inlet cooling systems like combined and simple cycle combustion turbines, and sunsetting the capacity-limited resource program, as these emergency capacity resources are rarely committed.

NYISO will finalize the approved tariff language with the Installed Capacity Working Group and continue discussions around correlated derates. The expectation is to present these revisions to the MC in the first quarter of next year for final approval before filing them with FERC.

Transmission Congestion Contracts

The BIC also voted to approve revisions to the transmission congestion contracts (TCC) manual presented by NYISO that incorporate updated technical bulletins addressing modeling assumptions for certain phase angle regulators (PARs).

The TCC manual was last updated in October 2021.

The revisions include updating the modeling descriptions for the “Internal Con Edison PARs” to include the Vinegar Hill PARs (Technical Bulletins Nos. 254 and 255) and revising the modeling assumptions for the “East Garden City PARs” and “Hurley Avenue PARs” from fixed schedules to schedules optimized by the optimal power flow (Technical Bulletins Nos. 257 and 258).

November Market Operations

NYISO Senior Vice President Rana Mukerji presented the November market operations report, saying a “slight uptick” in gas prices slightly increased locational-based marginal price, from $28.10/MWh in October to $34.90/MWh in November. The natural gas index price at Transco Z6 NY was $2.20/MMBtu in November, up from $1.30/MMBtu in October.

Year-to-date average monthly energy prices, however, were 55% lower than the previous year, dropping from $89.97/MWh to $39.32/MWh. This decrease was driven by the continued decline in gas prices throughout the year, with natural gas prices down 54.3% year-over-year at Transco Z6 NY.

Analysis Group Recommends Prompt, Seasonal Capacity Market for ISO-NE

WESTBOROUGH, Mass. — ISO-NE should move to a prompt and seasonal capacity market to better accommodate the evolving mix of resources and reliability risks in the region, Analysis Group told ISO-NE stakeholders at the NEPOOL Markets Committee (MC) meeting Dec. 13. The consulting firm recommended the RTO make the move for the 2028-29 Capacity Commitment Period (CCP). 

In November, NEPOOL voted to delay Forward Capacity Auction (FCA) 19 — which corresponds to the 2028-29 CCP — by one year to complete resource capacity accreditation (RCA) changes and consider moving to a prompt and/or seasonal capacity market. (See NEPOOL Votes to Delay FCA 19.) 

While FCAs currently are held more than three years prior to the CCP, a prompt capacity auction would be held just months before the CCP. Changing the auction to a seasonal format would break up the yearlong CCP into distinct seasons. 

ISO-NE has commissioned Analysis Group to study and make recommendations on the potential move to a prompt and seasonal auction format. The study has a condensed timeline to leave time for stakeholders to contemplate the impacts of the changes. (See Analysis Group Details Methodology of ISO-NE Capacity Market Study.) The firm released its draft results prior to the December MC meeting.  

Moving to a prompt and seasonal capacity market would “allow the region’s capacity market to adapt to and support the transition toward a grid of the future for the region,” Todd Schatzki of Analysis Group told stakeholders. He added the changes would “improve resource adequacy outcomes in both economic and reliability terms.” 

One of the key benefits of holding the auction closer to the CCP would be more detailed information on both supply and demand, Schatzki said. It also would entail less deliverability risk for new resources coming into the capacity market, since all resources bidding into a prompt capacity market would need to be ready to provide capacity. 

While the forward capacity market initially was designed to align with the development timelines of new power plants, the current timelines for new resources vary significantly between resource types, Schatzki said. While battery storage can arrive as soon as nine months, gas plants and offshore wind can take up to 48 months, he added.  

A prompt auction could provide a “more neutral competitive platform for new investment,” Schatzki said.  

Regarding a seasonal format, “a seasonal market can account for differences in the value of capacity in reducing reliability risks across seasons,” the draft report found. “By accounting for these differences when procuring capacity in each season, so that more capacity is procured in seasons with greater reliability risks, it can lower the costs and improve resource adequacy.” 

Analysis Group performed a limited quantitative assessment of the financial impacts of the capacity market changes, which found that prompt and seasonal changes would reduce costs in most cases, with the cost benefits ranging from 2% to 10%.  

The firm also found that a prompt and seasonal market likely would provide more incentives for firm natural gas fuel arrangements, because these fuel commitments often are made in the summer and fall prior to the winter. 

“Compared to a prompt market, making commitments three-plus years in advance would be expected to raise costs of these commitments and reduce the scope of firm fuel arrangements,” Schatzki said, noting that the under-development RCA updates also could increase incentives for firm fuel commitments. 

One basic drawback of a prompt and seasonal market would be the time and effort required to make such major changes, and administering seasonal auctions would mean more work for ISO-NE, Schatzki said.  

The draft report also noted that no other regions that heavily rely on capacity markets to meet resource adequacy needs have a prompt and seasonal capacity market. 

“However, other regions have, or are in the process of assessing or implementing, prompt and seasonal market designs, and the technical risks of developing a prompt-seasonal market appear manageable,” the report concluded.  

Schatzki added that some aspects of the market may need to be reconsidered if the RTO elects to move to a prompt and seasonal auction to avoid unintended consequences. These include the resource qualification and retirement processes, supply offer components and market mitigation.  

Looking forward, Analysis Group will present the final report at the January MC meeting, and ISO-NE is planning to make a recommendation on the capacity market changes at the February MC meeting. 

RCA Updates

The MC also discussed updates to the accreditation methodology for oil and gas resources.  

In the new RCA format, resources will be compared to a theoretical perfect capacity resource that lacks operating constraints. This method is intended to create a neutral point of comparison for the reliability and resource adequacy attributes of all capacity resources on the system.  

In ISO-NE’s proposal, gas resources’ firm fuel arrangements will affect their accreditation value, while oil resources’ accreditation value will be affected by their storage capabilities.  

Oil capacity for both oil and dual-fuel resources will be judged on an individual basis, while gas capacity will be estimated at a fleet level to account for the region’s seasonal gas constraints, ISO-NE said.  

“An aggregate hourly profile will be used in the winter period to represent the hourly gas fleet generation using the daily gas available to the fleet subject to the gas system limitation,” ISO-NE said.  

The aggregated gas fleet capacity value then will be allocated to individual resources, which could improve their accreditation through firm arrangements including firm gas supply and pipeline contracts, as well as added dual-fuel capabilities or LNG vaporization capabilities. 

Additional firm gas contracts that reduce the total amount of gas available to the rest of the fleet would lower the accreditation values of non-contracted gas generators, ISO-NE noted.

Federal Court Rules in Favor of Transource Congestion Project in PJM

A federal court has ruled that the Pennsylvania Public Utility Commission violated the Constitution’s Commerce Clause in denying Transource Energy a certificate of public convenience to construct the Independence Energy Connection (IEC) transmission project, ruling that the rejection was rooted in economic protectionism rather than siting concerns (1:21-CV-01101).

To proceed, however, the project will have to clear a new PJM benefit-cost analysis that considers other transmission projects approved in the last several years. (See Transource Challenges Pa. PUC Decision in Court.)

“After carefully considering defendants’ arguments, the court is not persuaded that the PUC’s decision was, in substance, about siting. Much of defendants’ argument attempts to deconstruct PJM’s analysis, following FERC-approved methodology, for assessing the project. Defendants’ argument picks apart the FERC-approved methodology and whether it was sufficiently open, allowed for evidentiary hearings, permitted cross-examination or allowed argument by interested parties. But in making these arguments about the various flaws in PJM’s analysis of the need for the project, defendants have not provided a substantive basis for this court to conclude that the PUC’s decision actually related to siting as opposed to determining whether there was a need for the project,” Judge Jennifer Wilson wrote for the U.S. District Court for the Middle District of Pennsylvania in a decision released Dec. 6.

The project is aimed at alleviating congestion on PJM’s AP South interface by constructing two 230-kV lines between Ringgold substation in Washington County, Md., to the Rice substation in Franklin County, Pa., and between the Conastone substation in Harford County, Md., to the Furnace Run substation in York County, Pa.

The PJM Board of Managers approved the project in 2016, stating that it was the most cost-effective way of addressing congestion in Virginia, Maryland, D.C. and western Pennsylvania. (See “Transource Re-evaluation,” PJM TEAC Briefs: Nov. 30, 2021.)

The Maryland Public Service Commission also approved the Maryland sections of the project in June 2020 in a settlement that included a reconfiguration of the Harford County section of the project to run in an existing Baltimore Gas and Electric right-of-way.

Due to the denial and Transource’s subsequent litigation, the PSC has granted the company and BGE a series of extensions on the deadlines for beginning and completing construction of the lines.

On Dec. 13, the PSC approved a third extension, to Dec. 31, 2024.

Similar extensions have also been approved for another component of the IEC, a Potomac Edison rebuild of an existing single-circuit 138-kV transmission line to a 230-kV transmission line between the Ringgold and Catoctin substations in Frederick and Washington counties, Md. Speaking at the PSC meeting Dec. 13, J. Joseph Curran III, an attorney with Venable and counsel for Transource, said the litigation was the primary driver of the extension requests.

The PUC defended its May 2021 decision to deny siting and eminent domain permits by arguing that the benefit-cost analysis PJM conducted didn’t address all the requirements for a project deemed to be necessary under state law and didn’t take into account the full breadth of costs — namely the increased rates some will pay should congestion be alleviated.

PJM’s market efficiency process considers whether the reduction in rates attributed to the project would outweigh its construction costs at a 1.25-to-1 ratio. In a 2020 reanalysis of the project, PJM estimated that it would reduce congestion costs $845 million and cost $509 million to $528 million, which would be assigned to ratepayers in the regions benefiting from the reduced congestion. (See Transource Tx Project Rejected by Pa. PUC.)

Transource argued that the commission was seeking to preserve the cheap power enjoyed in some areas at the expense of others without access to that energy due to congested lines. The company told the court that if states were to be permitted to reject projects on the basis that they don’t benefit their ratepayers, it would defeat the purpose of transmission planning aimed at alleviating congestion resulting in regional price disparities.

“If states could override FERC by applying a conflicting method for determining need, solely to preserve the benefits of congestion for their own citizens, that would eviscerate FERC’s ability to plan the interstate transmission grid in an efficient and fair manner,” Transource said in court documents.

The court rejected the PUC’s jurisdictional arguments, stating that the federal government’s interests go beyond planning projects and extend to seeing that they are built, with the states’ role focused on enforcing local siting, environmental and public safety regulations.

“The PUC is attempting to supplant the role of the RTO and expand its state authority into the regulatory territory occupied by the federal government. If permitted, the PUC’s second-guessing of the methods sanctioned by federal law and employed by the RTO would severely handicap the ability of FERC to ensure just and reasonable rates. Because the PUC’s decision presents an obstacle to achieving federal objectives, it is conflict preempted and violates the Supremacy Clause,” the court wrote.

The commission also argued that the congestion had decreased since 2014 and the project’s benefits would be lower than presented in PJM’s 2016 approval of the IEC project. The benefits would be further diminished, the commission said, if the benefit-cost analysis included the increased rates that might manifest once the congestion was eliminated.

PJM Re-evaluates

While welcomed by Transource, the federal court decision does not mean IEC is out of the woods. First, the PUC has 30 days to file an appeal, and some local permitting remains.

However, Hector Garcia-Santana, senior counsel for American Electric Power, which partnered with Evergy to form Transource, told the PSC on Dec. 13 the IEC projects are “very mature at this point. Materials are in the United States, and they are specific for the project. They are already in hand. The transformers, which are long-lead items, are already in the United States as well. … They were acquired at a time prior to now; so, the price for that type of equipment has increased since then.”

Garcia-Santana added that 70% of the rights of way for the projects have been secured, as well as rights for substations in Pennsylvania. Pending final approvals from the PUC, construction could take 12 to 18 months, he said.

Garcia-Santana’s optimism was somewhat tempered by William Fields, deputy people’s counsel in the Office of the People’s Counsel, who cautioned that PJM will be re-evaluating IEC in the spring of 2024 to consider whether it is still cost-effective and necessary “because of all the tremendous activity going on in this general area of the grid.”

Since IEC was originally approved, New Jersey has selected its first projects under its state agreement approach with PJM, intended to start building out the transmission needed for offshore wind projects, and the PJM board approved Window 3 projects for its Regional Transmission Expansion Plan (RTEP) on Dec. 11.

PJM filed a waiver request asking FERC for more time to complete its required annual reanalysis of the project in November due to how the RTEP projects could interact with the project.

“Performing a reevaluation of the Transource IEC Project before year end with a base case that does not resolve the 2022 RTEP Window No. 3 reliability violations will produce incomplete results until the market efficiency model is updated for reevaluation purposes, which will frustrate PJM’s ability to provide meaningful updates to the [Transmission Expansion Advisory Committee] and the PJM Board. Either way, performing an analysis on incomplete data is an inefficient use of PJM engineers’ time,” the waiver request argues.

The waiver request states that PJM staff will need about three to four months to prepare a base case including the approved RTEP projects to run the analysis on whether the IEC project continues to pass the benefit-cost threshold. It asks that FERC extend the deadline for the analysis to the second quarter of 2024.

PSC members also raised concerns about the potential closing of the 1,238-MW Brandon Shores coal-fired plant outside Baltimore. PJM has said taking the plant offline in 2025, as planned by owner Talen Energy, could result in “degraded grid reliability.”

Commissioner Michael T. Richard queried Fields on whether OPC or PSC staff have “had a chance to hear from PJM about how this cluster of [IEC] projects interacts with these other projects, and really, if they are still needed and cost competitive.”

“We don’t know exactly where PJM is going to be on that,” Fields said. “But it seems a good chance that [the IEC projects] have been overtaken by events from these other activities. I think the real question is going to be, in the spring, when PJM runs the power flow models … [will] they look and say, ‘How much is this going to save in market prices over the future, from that point on?’ And you compare that to the cost of the project.”

Fields told RTO Insider his office would support the project if it continues to promise the benefit-to-cost ratio PJM has projected in the past. However, he noted that it was approved years ago and the grid in that region has seen a lot of change.

“There’s been a huge amount of activity in this part of PJM with respect to new transmission that’s already been built, transmission that’s planned to be built, generation retiring and I think it’s an open question whether when PJM reevaluates the costs and benefits of this plan, if it’s still going to be beneficial in reducing customers’ energy bill,” he said.

PJM Board Approves $5 Billion Transmission Expansion

The PJM Board of Managers on Dec. 11 approved an estimated $5 billion package of transmission projects in the third window of its 2022 Regional Transmission Expansion Plan. 

In its announcement of the approval, PJM said it is forecasting 7,500 MW of new data center load in Virginia and Maryland, much of which is expected to be clustered around Dulles Airport in Northern Virginia. The RTO is also expecting about 11,000 MW in generator deactivations, most notably the 1,295-MW Brandon Shores plant outside Baltimore. 

The package is made up of dozens of components submitted by Dominion Energy, FirstEnergy, Exelon, PPL, NextEra Energy, Transource Energy and Public Service Enterprise Group. (See “Second Read of $5 Billion in RTEP Projects,” PJM PC/TEAC Briefs: Dec. 5, 2023.) 

The work includes constructing new 500-kV lines from Northern Virginia northeast to the Peach Bottom substation in Pennsylvania, northwest to the 502 Junction substation in West Virginia and south to the Morrisville substation in Southern Virginia. 

The board’s approval caps off a process that began with the opening of the competitive window for transmission owners to submit projects in February. The normal 90-day window was extended to close May 31, and PJM presented three shortlisted packages on Oct. 3 before an Oct. 31 presentation of the proposal to the Transmission Expansion Advisory Committee that it ultimately brought to the board. (See PJM Shortlists 3 Scenarios for 2022 RTEP Window 3.) 

Maryland Office of People’s Counsel Deputy William Fields told RTO Insider that presenting the recommended set of projects at the end of October with the plan of bringing it to the board in December left little time for stakeholders and the public to evaluate the projects and draft comments to the board to allow them to come to a fully informed decision. 

“It’s certainly true that this general issue has been talked about for many months, but we saw this actual list of projects Oct. 31 … and here it is weeks later being approved,” he said Wednesday. 

Fields said his office had received high-level information about cost allocation from PJM on Dec. 12 and is in the process of evaluating the potential impact to Maryland ratepayers. 

The functioning of the cost allocation formula in PJM’s tariff is understood by stakeholders, but Fields said that the scale of the package will present that methodology with a test it has yet to face. 

“We’ve just gotten some preliminary information, and we’re trying to evaluate it and look at it in more detail. But the question is, does the usual allocation method produce reasonable results when you’re talking about extremely large amounts of new load?” he said. 

During the second read of the proposal at the TEAC meeting Dec. 5, several members of the public objected to the package, citing concerns about disruption to historic regions along the proposed route, the inclusion of greenfield construction components, the cost and the likelihood of requiring additional major transmission expansions should load growth continue in the region. 

PJM’s Sami Abdulsalam said the proposal represented the most efficient, cost-effective and resilient combination of the 72 project submissions received during the competitive window and that minimizing greenfield disruption and siting risk were among staff priorities. The RTO included with its TEAC meeting materials an FAQ detailing its role in selecting the proposals in the window.

Washington State’s Cap-and-trade Auction Generates $373M

Washington raised another $373.6 million in its final carbon emissions allowance auction for 2023, the state Ecology Department announced Wednesday. That translates to the state raising slightly more than $2 billion in 2023, the first year of what the state refers to as the “cap-and-invest” program.   

In Washington, carbon-emitting corporations bid every three months on state allowances for the pollution emitted by their facilities. The winning bidders all pay the same price on these allowances after the auction. The “settlement” prices in the first few Washington auctions were $48.50 for roughly one metric ton of carbon for the first quarter of 2023; $56.01 for the second quarter; and $63.03 for the third. The result of the Dec. 6 auction, which was announced Wednesday, was a settlement price of $51.89 per allowance.  

The cap-and-invest system, passed by the Legislature in 2021, is aimed at decreasing carbon emissions to a fraction of their current levels by 2050. The program has been linked to an increase in Washington’s price at the gas pump from 15 cents to 50 cents per gallon, depending on who’s doing the calculating. Republicans have been slamming Democratic Gov. Jay Inslee over those increases.  

Washington traditionally has had one of the highest gasoline prices in the nation due to various geographical and economic factors outside of the cap-and-invest program.  

The Washington Legislature has appropriated $2.1 billion in cap-and-invest revenue to be spent on numerous climate mitigation programs from July 1, 2023, through June 30, 2025. On Monday, Inslee announced the state expects to collect $941 million in extra cap-and-invest program money in the first half of 2024, bringing the overall income to roughly $3 billion over the system’s first 18 months.   

The extra $941 million will be added to Inslee’s 2024 supplemental budget request to the Legislature in January. It’s up to the Legislature whether it will approve some or all of that request, which includes:  

    • A one-time $200 credit to the utility bills of roughly 750,000 low- and moderate-income households in Washington;  
    • Speeding up the transition from diesel school buses to electric zero-emission school buses across the state;   
    • Installing electric heat pumps in low-income multiple-family homes, replacing gas heat;  
    • Providing matching funds for competitive federal grants to obtain clean energy jobs; and   
    • Converting a large diesel ferry into to a hybrid fuel-electric ferry. Washington’s ferries are breaking down in increasing numbers. Inslee said Monday that future cap-and-invest income could speed up replacing the old ferries with new hybrid ferries.

NERC: Growing Demand, Shifting Supply Mix Add to Reliability Risks

Rising demand and the potential for higher generator retirements are raising reliability concerns over the next 10 years, NERC said in its 2023 Long-Term Reliability Assessment, released Dec. 13.

“In our latest assessment, it really confirms that we’re in an absolute step change in terms of the risk environment we’re seeing on the system, both in terms of reliability, as well as energy assurance,” John Moura, NERC director of reliability assessment and system analysis, said on a webinar with reporters. “The electric power industry continues to face challenges in the future: a rapidly changing resource mix, threat landscape, extreme weather and inverter-based resources.”

Moura said ensuring reliability as the resource mix changes involves stopping plants from retiring early and making sure new resources can provide enough of the same needed services.

Peak demand net energy growth rates in North America are growing more rapidly than at any point in the past three decades, according to the LTRA. Electrification of heating and electric vehicles, as well as increased demand from commercial and industrial customers such as data centers, has reversed the decadeslong trend of falling or flat growth rates.

The aggregated summer peak demand forecast is expected to grow by 79 GW over the next 10 years, while winter demand growth is expected to rise by nearly 91 GW in the decade. Winter demand is growing so fast that NERC expects the Northeast and Southeast to become winter-peaking, or at least dual-peaking, in the coming years.

The supply side is seeing overall growth, dominated by solar power, while fossil generation is expected to decline in the coming decade.

“We are projecting moderate growth,” NERC Manager of Reliability Assessments Mark Olson said. “But it’s not quite keeping up with where the demand projections are going in this most recent forecast that we received. Our total capacity growth is expected to be about 34 GW over the next 10 years.”

New England and New York are expected to have higher winter peaks by the mid-2030s, while the Southeast has already gone through changes.

“SERC-Central and SERC-East became dual-peaking systems in recent years,” the report says. “SERC-Southeast recently began experiencing slightly higher peak demand in winter compared to summer.”

SERC-Central, made up of six states centered around Tennessee, joins MISO as one of the two “high-risk areas” in NERC’s report. That means they are more likely to have insufficient supplies to meet demand at some point in the next decade.

Despite its high risk, MISO has actually improved since last year, when shortages were expected this year, but delayed retirements and some new resources now have NERC expecting a 4.7-GW shortfall in 2028. SERC’s shortfall is expected to hit in 2025-2027 as the region retires 5 GW of coal and brings online 7 GW of natural gas.

Many more regions were “elevated risk areas,” meaning NERC is not worried about them in normal weather, but their systems could run into issues under extreme conditions. Five of the ISO/RTOs are included in the category.

California has also improved because of new capacity additions, as now NERC is expecting negligible risks next summer, but it warns by 2026 that unserved energy risks emerge in the summer.

ERCOT is seeing huge additions of solar power but faces elevated risks during the off-peak periods when its output is lower. Those risks are during peak summer days, and when dispatchable generation is down for maintenance in the shoulder months. Extreme winter weather is also still a concern and warrants continued efforts ensuring generators and the fuel they need to keep running remain available.

New England continues to face elevated risks in the winter with persistent concerns about fuel availability being exacerbated by electrification as its winter peak demand growth rate is the highest in North America, with a 3.46% compound annual growth rate over the next decade.

NERC confirmed NYISO’s own reliability studies, which show a risk of shortfalls for New York City starting in 2025 as peak demand rises and generators become unavailable because state laws reducing the emission of nitrogen oxide.

SPP has a surplus now, but it is going to drop rapidly over the next few years because of retirements and rising peak demand. The RTO also raised its reserve margin from 16% to 19% in the past year.

The only RTO to have a normal risk level — meaning NERC expects its system would handle even extreme conditions — is PJM. While NERC’s forecast has healthy reserve margins in PJM throughout the decade, it noted that accelerated retirements and higher demand growth could still pose challenges in the later years of its assessment.

Ultimately, the shortfalls NERC identified in its report can be resolved with additional procurements of supply, Olson said.

The power industry’s ongoing transition is playing a role, as the move to net-zero emissions is driving electrification that is pushing up demand and is also changing the resource mix on the supply side of the equation. The industry, policymakers and regulators all have to balance reliability with affordability and addressing environmental concerns, Moura said.

“I think when we get tripped up is when in how we prioritize those,” he added. “And so, reliability is something that needs to be prioritized. It’s the heart and soul, for the health, safety and the prosperity of our consumers and all of our communities. And so that needs to be at the heart of it.”

As policy continues to move forward on net-zero issues, reliability must not be forgotten, and the industry needs to continue focusing on it, Moura said.

Reactions to LTRA Highlight Risks

National Rural Electric Cooperative Association CEO Jim Matheson put out a statement saying EPA’s proposal to curb emissions from power plants would only exacerbate the situation NERC’s report highlights.

“NERC’s latest assessment paints another grim picture of our nation’s energy future as demand for electricity soars and the supply of always-available generation declines,” Matheson said.

The coal power trade group America’s Power also used the report to highlight its qualms with recent energy policies.

“Unfortunately, NERC’s latest assessment is deeply troubling because it indicates that, despite several years of warnings about the possibility of electricity shortages in many parts of the country, the risk of electricity shortages has grown worse,” said America’s Power CEO Michelle Bloodworth. “This is largely due to coal retirements, EPA policies and dangerous subsidies for unreliable sources of energy. We again urge Congress and federal and state policymakers to act immediately on these continued warnings.”

On the other side of the debate, the World Resources Institute held a webinar earlier in the day to highlight a new working paper on how to maintain reliability throughout the clean energy transition. Author Kelli Joseph, WRI senior fellow, noted it was more focused on operating reliability, while the LTRA is all about resource adequacy.

“We don’t spend as much time talking about operating reliability,” Joseph said on a webinar. “And I think what we need to recognize going forward, especially through the transition, is that operating reliability becomes a bit more challenging.”

Operating reliability refers to the ability of the system to withstand sudden disturbances, which many of NERC’s mandatory standards address.

If anything, the clean energy transition is going to make reliability more important, as more of the economy is connected to the grid through electrification, Karen Palmer, director of Resources for the Future’s electric power program, said at the WRI event.

“But it’s also important in the near term for continued progress on electricity sector decarbonization,” Palmer said. “Any reliability events or outages or mandatory load-shedding events that could be in any way pinned on decarbonization efforts, rightly or wrongly, could really stall clean energy progress in its tracks. And that wouldn’t be good for meeting domestic and international climate targets.”

Good COP, Bad COP: Thoughts from the Edge of COP28

NetZero Insider correspondent Dej Knuckey | © RTO Insider LLC

DUBAI, UNITED ARAB EMIRATES — When an official meeting the size of COP28 brings powerful people to one place, a slew of conferences and events emerge on the periphery like a fairy circle. Put COP in a city known for tourism and well-equipped for a mass influx, and the side events begin to challenge the main show. 

So while most journalists at COP28 were in the Blue Zone, where the global negotiations and other official meetings were held, I took a tour of the edge, attending events hosted by analysts and news organizations (S&P Global, The Wall Street Journal and Bloomberg Green), consultants (IDEO, McKinsey, Neol), incubators (Future Mobility Hub, Hub 71) and the sizeable Climate Action Innovation Zone, an umbrella event for multiple summits, forums and roundtables. And there was one event that can’t be named, but I’ll get to that later. 

One Phrase to Hold on To

“Slow, then fast.”  

It was a comment about change, about innovation, about the many new technologies in our world that, once they got going, accelerated faster than anyone could imagine. That phrase came back to me countless times in the days that followed. 

Personal computers, cell phones, cars, lightbulbs: once they started to take off, they quickly became ubiquitous. And in the same way cell phones leapfrogged the Global South to better connectivity without the interim and expensive step of building landline infrastructure, climate solutions may leapfrog the most climate-harmed parts of the world to a clean energy future without the dirty and slow steps of building hydrocarbon-based generation and a grid. But it will require change that is “slow” today to quickly scale to “fast.” 

Slivers of Hope in Unexpected Places

The topics covered by the multitude of events were rarely surprising: challenges in financing the energy transition, advances in the hard-to-decarbonize steel and concrete sectors, accelerating green building, the future of mobility. All interesting, but little new. The frank admissions that we are not moving fast enough and there are massive hurdles that could not be solved by the Blue Zone alone were not surprising to anyone who follows climate solutions. The same faces appeared at the different conferences, and when I found myself watching John Kerry, the U.S. special presidential envoy for the climate, for the second time, I knew it was time to dive into topics I knew less about.  

Yet for all that is not moving fast enough, there were slivers of hope in unexpected places.  

One area of hope came from the insurance industry: Small changes in underwriting rules can lower project insurance costs and open up better financing. Two examples: First, an industry-wide decision to define “nuclear” in a more nuanced way means that the risks of fission will no longer impact the cost of insuring fusion projects; second, after studying cross-laminated timber (CLT), an important green building material, a major underwriter reassessed its risk and will make buildings using the material easier to insure. The insurance industry had assumed CLT reacted to water the way the Ikea pressboard cabinet in your college dorm did after a spill. Not so. 

Another surprising sliver of hope came from a comment tossed out on a panel about lowering carbon in industrial projects. Pumps account for around 10% (10%!!!) of all energy consumed, a solid two TW-years, yet most pumps are highly inefficient. New technologies could make pumps 80% more efficient, unlocking massive savings from a simple piece of technology we all use daily and rarely think about.   

John Kerry shared news about global satellite methane tracking, giving hope that increased visibility will end the massive methane leakages in oil- and gas-rich basins that are currently uncounted in emissions statistics. 

Finally, there was a story about toothpaste that’s worth a full article. But the bottom line that inspired hope was that one of the world’s largest consumer goods companies, Colgate-Palmolive, is sharing its IP to enable toothpaste tubes — which contain aluminum mixed with plastic — to become recyclable. 

A Visit to the Green Zone

Within COP28 itself, the Green Zone is where all those without credentials — neither press nor official negotiating parties — can visit freely. While the first few days of the Green Zone required an invitation, by day four, events were open to anyone who registered online, including numerous groups of elementary school kids.  

Inside the tented “hubs” spread out across the massive Expo 2020 site, it was trade-show-as-usual, albeit with fewer salespeople. The Climate Finance Hub had large booths mainly sponsored by banks; the Energy Transition Hub had yet more booths and scale models of green hydrogen and renewable energy plants. Aside from the Knowledge Hub, which was home to McKinsey’s stage and a handful of other consulting firm booths, most hubs were dominated by major corporations based in the Middle East. It was interesting for a day, and the stages in the hubs had a few good panel discussions, but most of the Green Zone felt like an ad for doing business in the UAE.

Long on Questions, Short on Answers

There are meetings around the skirts of COP28 that aim to make a difference, but it was rare to find one that really could have. I found myself at an invite-only event in the stunning Museum of the Future. It was the first time ever that I needed both hands to count the number of billionaires in the room. Add in former and current prime ministers, presidents and indigenous leaders, and I’d be taking off at least one shoe.  

Held under Chatham House Rule, the details and attendees are confidential, but the gist is shareable. The intent was idealistic: a frank conversation about hard-to-solve issues, a focus on building models for the future, with everyone as participants, not audience. Yet even at this confluence of changemakers and captains of industry, the micro-TED-talks of the distinguished guests left little time for the hoped-for conversations. 

I left at lunch — hurrying off to the next event — with scribbled notes on a page labeled “What if?” and questions that I wanted to ask should the microphone have ever reached me: 

    • What if we incent the hydrocarbon industry to strand dirty assets sooner? Do we finance the unbuilding of damaging sectors or is that rewarding past bad behavior? 
    • What if a “protection sector” is paid to protect and regenerate nature, and in a self-perpetuating way? Can blended financing change the mindset about risk in developing nature-based solutions? 
    • What if the cost of clean energy in far-flung regions is brought closer to parity with the developed world, when today solar, for example, costs 20 to 50 times as much on a Pacific island as in major markets? 
    • What if we preemptively manage the loss and damage that remote and indigenous communities will suffer as we ramp up mining for the essential ingredients of a cleaner future?

A Fountain of Excess

If you haven’t been to Dubai, imagine Vegas but bigger, hotter and newer. A lot bigger, hotter and newer. With a bigger, higher and more-Bellagio-than-Bellagio fountain at the base of the highest built structure in the world. Excess, thy name is Dubai. 

Aside from the offensiveness of extreme wealth displays in a city whose wealth was derived from the very industry that is destroying poor parts of the planet, it does have one aspect that gave me hope: This whole invented place shows just what massive amounts of money can build when it’s spent with resolve. And solving climate change will require more money and more resolve than a thousand Dubais. But if Dubai is doable, perhaps solving climate change is too. 

An Oasis of Hope in the Desert

There’s a much-needed day off in the middle of COP, though it was my last day in the UAE. I traveled with clean energy accelerator New Energy Nexus to an agricultural incubator launched by Silal, a diversified ag leader in Abu Dhabi with an eye on the region’s food security.  

After more than an hour driving through flat sandy lands dotted with camels and low-slung buildings, we turned off the highway to a dirt road surrounded by construction vehicles. Two more turns, and I was on the doorstep of two startups building a new ag future: Desolenator and iyris by Red Sea.  

They deserve a deeper dive, which will come, but I left with hope: If solar panels can supply clean water and a literally cool greenhouse can deliver a mountain of cherry tomatoes amid the desert, perhaps humankind can innovate fast enough to stay ahead of climate-driven food shortages. 

Whether green innovation and capitalism can solve the climate crises created by last century’s hydrocarbon-centered innovation and capitalism is unclear. What is clear is that innovation and capitalism are moving faster than diplomacy. The final day of COP28 yielded some groundbreaking agreements on cutting fossil fuel use — albeit less vigorous than many had hoped for — but policy doesn’t always precede action.  

Innovations in risk management, finance, corporate cooperation, energy efficiency, hard-to-decarbonize sectors, clean energy and food may drive change that is “slow, then fast.” And we need to reach “fast” as soon as we can.

LP&L Moves Remaining Customers into ERCOT System

ERCOT said Dec. 12 it has completed the largest single transfer of customers in its history with the final migration of Lubbock Power & Light (LP&L) customers from SPP.

The city of Lubbock joins San Antonio and Austin as municipalities in ERCOT’s competitive retail market. The more than 107,000 LP&L customers will be able to begin choosing their power providers in January.

That is a big change from the West Texas city’s previous experience with “alley-by-alley” competition that existed until 2010, said Matt Rose, LP&L’s public affairs and government relations manager, this year.

During the Gulf Coast Power Association’s fall conference in October, Rose recalled when LP&L and Xcel Energy subsidiary Southwestern Public Service (SPS) both had distribution facilities on either side of alleys.

“Depending on who you wanted to go with, you chose and then you got hooked up on one side in the alley or the other,” he said.

In 2010, LP&L bought SPS’ infrastructure and LP&L became more of a traditional municipality, serving all the customers in its footprint as a vertically integrated utility. Faced with spending about $700 million to build more generation, LP&L reached a decision point in 2014.

“We said, ‘We have a choice. We can build a power plant, stay in the Southwest Power Pool and operate as we have the past 100 years. Or we can take a look outside Lubbock.’ We could see that these transmission lines for ERCOT are really one county north, east and south of us,” Rose said, alluding to ERCOT’s transmission system.

LP&L said in 2015 it intended to transfer its load to ERCOT, beginning a process that culminated with the Public Utility Commission’s approval three years later. The process involved paying SPS $77.5 million for early termination of a power contract that would have cost the utility more than $17 million a year through 2044. (See Texas PUC OKs Sempra-Oncor Deal, LP&L Transfer.)

The utility successfully transitioned 70% of its load to ERCOT in 2021. The remaining 30% was moved into ERCOT in what LP&L said was a “seamless migration,” beginning early Dec. 9 and concluding midmorning Dec. 11.

Now, rather than choosing a provider on one side of the alley or the other, LP&L consumers can select from more than 85 retail providers during a six-week “shopping” window that begins Jan. 5. The utility then will begin migrating the customers to their chosen providers in March and become a transmission and distribution entity.

“This has been an interesting and a fun experience, but Lubbock was able to do this because Lubbock is uniquely situated,” Rose said. “We were ending all business in the Southwest Power Pool in order to move to ERCOT, and that allowed us the liberty to go pursue this.”

Study Finds 11% Dip in Housing Prices Near Wind Turbines

A newly published Berkeley Lab study finds that sale prices temporarily decrease for property located within a mile of newly announced and newly built utility-scale wind projects.

The conclusion runs counter to earlier studies published by the lab, some of which were compiled by some of the same researchers but relied on limited sales data.

During a webinar Dec. 13, one of the authors said vastly more real estate transaction data is available now than a decade ago, many more large-scale wind turbines have been erected, and the methodology for analyzing the information has evolved.

The bottom line: Shortly after a commercial wind turbine site is announced, houses located within a mile begin to sell for less than those three to five miles away from the same site. Over the next nine years, the difference grows to 11% on average, then gradually declines until the disparity is statistically insignificant.

“We see a dipping of values after the announcement of the project that kind of bottoms out right around the ending of construction and the beginning of operation,” said Ben Hoen, a research scientist at Lawrence Berkeley National Laboratory.

Hoen, Eric J. Brunner, Joe Rand and David Schwegman are the authors of “Commercial Wind Turbines and Residential Home Values: New Evidence from the Universe of Land-Based Wind Projects in the United States,” which was published this month in the journal Energy Policy.

To reach their conclusions, the researchers took CoreLogic’s database of more than 260 million U.S. residential property transactions from 2005 through 2020 and cross-referenced it with the 72,000 towers listed in the U.S. Wind Turbine Database.

After applying a rigorous set of filters and conditions, they were left with 496,000 transactions within five miles of a turbine rated at more than 600 kW; those transactions occurred no more than four years before and 10 years after the turbine was announced.

The greatest price impacts were seen in the 20,331 properties within a mile of a turbine that had been announced or built.

That is vastly more data than some of the previous studies. A 2009 report described by Berkeley at the time as “major” analyzed not quite 7,500 transactions in total.

That study and other studies found no statistically significant impact on sale prices.

But more recent studies in the EU and southern New England did show a negative impact on sale price of houses near wind projects.

“This was a curious finding for us,” Hoen said, “given our past work of not finding statistically significant impacts.”

A key factor is Europe is that the population density is much greater than in the United States, the authors said. It is harder to site a wind turbine away from people there. Similarly, the housing price impacts recorded in Massachusetts and Rhode Island were greatest in the more densely populated eastern portions of those states.

Finally, the authors emphasize that in their own analysis for the new study, the greatest price impact was seen in counties that were part of, or adjacent to, metropolitan areas with population greater than 250,000.

Wind power’s impact on home prices is not just a statistical curiosity. It can be a significant factor in building support for a project.

“Property values remain one of the top concerns for local communities that are considering hosting a wind energy project, or have a wind energy project in their midst,” Hoen said. “Often, a home is a family’s most valuable asset, and therefore protecting [it], and protecting its value, is of extreme importance.”

Because a geographically identifiable group of residents has been shown to be impacted economically by wind power projects, it may be possible to directly compensate them, the authors write.

And because the impacts of a project have been shown to begin well before any wind turbines are erected, it may be possible to do a better job explaining the actual impacts of the towering equipment, rather than leave it to speculation. Better line-of-sight photo simulations or location-specific audio simulations might help ease the concerns of nearby residents and the people who buy their homes.

Hoen said the analysis found no variation by size. The largest wind turbines had the same effect on prices as their smaller cousins.

Nor, he said, was there any attempt with this study to analyze the positive impacts of wind power generation, such as job creation or tax revenue.
