PJM TEAC Briefs: Sept. 9, 2025

Update on New Jersey and Maryland SAA

PJM and the New Jersey Board of Public Utilities are in discussions on how the transmission and interconnection facilities planned for the state’s offshore wind aspirations can be put on ice in the wake of all the generation developers pulling out of their projects. (See N.J. Puts on Hold Remaining Pieces of $1.07B OSW Transmission Project.)

The RTO has responded to a BPU request to pause transmission planned under FERC Order 1000’s State Agreement Approach (SAA) by asking for clarification on what a “delay” means and to clarify that PJM requires amendments to the SAA and designated entity agreements for those tasked with developing the transmission. That includes new in-service dates for the OSW projects and a solicitation schedule for finding new developers for the generation.

PJM Senior Manager of Policy Initiatives Susan McGill told the Transmission Expansion Advisory Committee that the RTO’s request is not adversarial but meant to ensure that the BPU’s request can be fulfilled to the greatest degree possible without compromising reliability. She added that staff have also reached out to all entities involved in the SAA projects.

Planning staff have sorted through the SAA transmission to identify radial expansions with no impact on reliability, which can likely be deferred without issue, and multi-driver projects, which support both OSW interconnection and larger reliability needs or the interconnection of unrelated generation. Multi-driver projects may have to proceed regardless of the BPU’s request.

PJM is also processing a request from the Maryland Public Service Commission to use the SAA to support its goal of installing 8,500 MW of OSW by 2031. The two are working to draft an approach on how to proceed with the SAA, which would be PJM’s second, with the goal of the RTO completing its analysis and opening a competitive window for transmission projects in 2026.

The RTO has conducted an initial study on possible interconnection points based on the 2024 Regional Transmission Expansion Plan (RTEP) case, the results of which led the state to support a plan with five injection points. The scenario identified would begin with injecting 2 GW at Delmarva Power’s Indian River substation in 2028, followed by 3,500 MW in 2030 split equally between the utility’s Cool Springs, Piney Grove and Nelson sites. The last 2 GW would come online at PEPCO’s Calvert Cliffs substation in 2031.

McGill said PJM staff and transmission developers participating in the New Jersey SAA competitive windows found having two separate windows was disruptive to the RTEP process, so the intention going into the Maryland SAA is to have one solicitation and window.

PJM Presents RTEP Update

PJM is evaluating 134 proposals submitted, of which 57 are classified as greenfield and 77 as upgrades, in the 2025 RTEP Window 1 competitive window, which closed Aug. 18.

The projects also include grid-enhancing technologies, with five involving HVDC lines and five advanced conductor proposals.

PJM’s Matthew Wharton said there’s a need for solutions providing west-to-east transfer capability, with most of the corresponding submissions focusing on expanding the 765-kV backbone. Many of the 500-kV proposals focus on improving north-south flows within the eastern side of the RTO. The proposals are skewed toward higher-voltage solutions, both in number and cost, with 56 involving 500-kV projects and 29 at the 765-kV level.

Wharton said the projects have been reviewed for deficiencies, and PJM is waiting for responses from the submitters. Staff plan to review the proposals and pursue a first read on noncompetitive projects during the TEAC’s October meeting, with recommendations on competitive projects to be held throughout the winter. The RTO’s goal is to receive Board of Managers approval for a package in the first quarter of 2026.

Generation Deactivation Update

Vistra has notified PJM that it intends to deactivate two coal-fired units at its Kincaid generator with an installed capacity of 1,112 MW. The deactivation notice states that the company is seeking to bring the units offline by Nov. 30, 2027, to comply with the EPA’s coal combustion residual rule.

Milepost Power has also submitted a deactivation notification for its 31-MW gas-fired Forked River Unit 2 because of “its inability to meet New Jersey air permit requirements.” The company initially requested to bring the unit, located in the JCPL zone, offline on June 1, 2026, but shifted that out by one year.

PJM’s Michael Herman said staff have completed a reliability analysis on requests to deactivate Warren Evergreen CT 1 and Cooper Unit 1, together amounting to 121 MW, and did not identify any violations.

Supplemental Projects

AES Ohio presented a $74.1 million transmission project to serve a customer near Marysville, Ohio, seeking to ramp its load to 135 MW by July 2028; the customer plans to initially come online in February 2027 with 22 MW.

The project would construct a new 138-kV substation in a breaker-and-a-half (BAAH) configuration cutting into the 138-kV Millcreek-AD2-163 line and expand the Darby substation with a 138-kV BAAH yard. The new substation would be connected to Darby with a 5-mile 138-kV line. The project is in the conceptual phase with an in-service date in April 2028.

Duquesne Light Co. presented a $46.3 million project to fulfill a new service request seeking to bring 250 MW to Monroeville, Pa., with a projected in-service date in January 2029. It would construct a new 138-kV substation, named McGinley, in a BAAH configuration with 12 breakers and a 50-MVAR capacitor bank. It would be looped into the 138-kV Cheswick-Yukon and Springdale-Huntington lines.

PPL presented a $187 million project to serve a customer seeking to bring 300 MW to Gouldsboro, Pa., ramping to 1.5 GW in 2030. The project would construct a 230-kV BAAH substation, named Big Bass, along the 230-kV Pocono-Acahela line to connect to two 230/34-kV substations to serve the customer. The 230-kV corridor between Paupack-Pocono-Acahela would be upgraded with an additional circuit, which would also extend from Acahela to Jenkins and from Paupack to Callender Gap and Lackawanna. Several of the substations along the corridor would be upgraded with new bays and breakers to accommodate the additional circuit.

PPL also presented a $95 million project to serve a customer seeking 230-kV service in Hazleton, Pa., for a load coming into service in 2027 with 350 MW to ramp to 1 GW in 2030. The project would reconductor the 10-mile 230-kV Susquehanna-Tomhicken line and construct a new 230-kV line from Harwood, through Slykerville and to Tresckow. The new corridor would initially be single-circuit, with the intention of upgrading it to double-circuit. The Harwood, Slykerville, Tresckow and Nescopeck substations would be upgraded with 230-kV bays, and three 230-kV line terminals would be installed at Tresckow for the lead lines to the customer substation. A new 500/230-kV transformer would be installed at the Susquehanna 500-kV yard, and a 3.75-mile 230-kV line would be constructed from the 500-kV yard to Nescopeck, initially as single-circuit but to be upgraded to double.

Exelon presented a $590 million project to address issues aging and faulty equipment in the D.C. area by replacing the deactivated Champlain substation with a 230/69-kV station with gas-insulated, BAAH buses for both voltages and three 230/69-kV transformers. The Takoma substation would be upgraded with two 500-MVA phase-shifting transformers to control power flows and prevent overloads in N-1-1 contingencies. The work would create a new 69-kV source to the D.C. core and allow the L Street substation to retire. It would also enable the retiring of 11 oil-filled cables under the Potomac River that have seen operational issues.

Exelon presented a $84.8 million project to serve a customer seeking to bring 225 MW to the Hoffman Estates region of the ComEd zone in September 2028, with the expectation to ramp to 612 MW in 2031. A 345-kV substation, named Beverly Road, would be constructed with two 150-MVAR capacitor banks and a double ring bus to be expanded to a BAAH. The facility would cut into the 345-kV Libertyville-Tollway and Silver Lake-Wayne lines with two half-mile, double-circuit lines. The project is in the conceptual phase with a projected in-service date of Sept. 1, 2028.

Dominion Energy presented a $56.5 million project to construct a 230-kV substation, named Azalea Lane, along the Brambleton-Evergreen Mills line. The facility would serve load growth in Loudoun County, Va., with a requested in-service date of Dec. 31, 2029. The substation would be configured in a four-breaker ring.

The utility also presented a $20 million project to resolve a 300-MW load drop violation identified in the 2025 Do No Harm analysis, which would cause the Racefield and Reed Farm substations to be offline. The solution involves upgrading Azalea Lane and Reed Farm to six breakers and constructing a double-circuit 230-kV line between the two. The project is in the conceptual phase with a projected in-service date of Dec. 31, 2029.

Rappahannock Electric Cooperative has requested a new substation, to be named Matta, in Caroline County, Va., to serve a data center coming online on Dec. 1, 2026, and expected to ramp to 300 MW by 2031. The project is expected to cost $25.5 million, including $18.1 million for the substation and $7.4 million to cut into the Ladysmith CT-Kraken line.

Public Service Electric and Gas presented an $85 million project to provide relief for the Mount Laurel substation in New Jersey, which has a projected contingency overload of 115.3%. The solution would construct a 230/13-kV substation along the 230-kV Cox’s Corner-Burlington line and feature two 230/13-kV transformers. The project is in the conceptual phase with a possible in-service date in May 2031.

PNW on Track to Meet Energy Savings Goals, NWPCC Finds

The Pacific Northwest is on track to meet energy efficiency goals set in the Northwest Power and Conservation Council’s 2021 power plan after having saved 160 aMW through improvements in 2024, the council said in a news release.

The 160 aMW in 2024 is up from 157 aMW in 2023. In total, the region has saved 465 aMW since the 2021 power plan was adopted in February 2022, putting it on track to hit the plan’s target of 750 to 1,000 aMW by 2027, the council stated in the Sept. 11 release.

“The council’s power plans protect the Northwest electricity grid’s reliability and adequacy, and cost-effective energy efficiency has been a crucial part of our strategy,” council board member K.C. Golden, who represents Washington, said in a statement. “The region is making key progress on our most recent plan’s target, but we have more work to do in the next two years. Acquiring the full target by 2027 will achieve the greatest benefit for the Northwest’s electricity grid and energy consumers in our region.”

Approximately 39 aMW of the 160 aMW in savings came from the Bonneville Power Administration, according to the news release.

The results are based on an annual survey conducted by the council’s advisory committee, the Regional Technical Forum. Participants in the survey include BPA, the Energy Trust of Oregon, the Northwest Energy Efficiency Alliance, and investor- and consumer-owned utilities in Washington, Idaho, Oregon and Montana.

Commercial buildings accounted for 50% of the savings in the 2024 survey, while the industrial sector accounted for 26%, the residential sector 22% and the agricultural sector 2%.

The region has increased spending on energy efficiency over the past three years. It invested $386.7 million in 2022, $456.2 million in 2023 and $580.6 million in 2024, the council said.

“This increase in funding comes after a period of declining investment in this resource,” according to the news release. “This trend likely reflects the renewed need for energy efficiency in meeting regional load growth. Budgets are forecast to grow by 12% in 2025, compared to 2024 levels. Continuing this trend will be important to achieving the 2021 plan’s full target by 2027.”

In total, the region has saved 8,042 aMW over the past 45 years, according to the council.

The savings report comes as the council prepares its ninth power plan, which will have a 20-year outlook for the region’s grid.

The council is required under the Northwest Power Act “to develop a plan to ensure an adequate, efficient, economical and reliable power supply for the region,” according to its website. NWPCC publishes a plan every five years, and the goal is to have a draft ninth power plan by July 2026 and a final version by the end of that year. (See NWPCC’s Initial Demand Forecast Sees Sharp Growth for NW.)

“The council’s power plans and collaboration with regional partners have made the Pacific Northwest a national leader in acquiring cost-effective energy efficiency,” Margi Hoffmann, Oregon council member, said in a statement. “Efficiency saves consumers and businesses money on their energy bills, makes our homes safer and more comfortable, and helps ensure the Northwest’s power supply continues to be adequate and reliable.”

PJM Operating Committee Briefs: Sept. 11, 2025

Update on BGE Load Shed Event

PJM’s Kevin Hatch presented to the Operating Committee an update on the Aug. 11 load-shedding event in Baltimore, which brought 20 MW offline for about half an hour following equipment failures at the Brandon Shores substation. (See PJM: Baltimore Load Shed Caused by Tx Equipment Failure.)

Issues began to mount at the facility at 3:39 a.m. when the 230-kV Brandon Shores-Riverside line tripped, followed by the 230-kV line to Waugh Chapel coming out of service at 5:18 and a 230-kV bus tripping at Brandon Shores. At 5:56 another 230-kV bus tripped and the line to the Wagner substation went offline. At 7:39 a.m. the whole substation went offline after the transmission to Brandon Shores and a second 230-kV line to Waugh Chapel went offline.

PJM implemented several emergency procedures throughout the day, starting with calling 120-minute pre-emergency load management at 8:45 and the 30- and 60-minute products 15 minutes later. Demand response deployments lasted until 8 p.m. As load ramped up toward the afternoon peak, PJM called emergency load management at 2:15 p.m., instituted a 5% voltage reduction at 3 and directed load shed at 3:52.

Hatch said the load shed mitigated an N-5 cascade contingency that put about 1.2 GW at risk when load in the BGE zone exceeded 4.9 GW, which it was forecast to do at 3 p.m. before rising to a peak of about 5.2 GW at 6 p.m. The DR deployments brought load down by about 230 MW, with an additional 60 MW provided by the voltage reduction and 20 MVA from a few combustion turbines that were able to be brought online.

“We took all corrective actions we could to reduce risk to the system,” Hatch said.

Some PJM systems showed the emergency procedures as a trigger for a performance assessment interval (PAI), but Hatch said no PAI was initiated because of the localized nature of the event. He said the RTO is exploring changes to its reporting of emergencies to establish that a voltage reduction in a single zone does not automatically start a PAI, which would subject generation owners to Capacity Performance penalties if they underperform their capacity commitments. He said staff also plan to create a simulation of the event for future training.

Stakeholders Discuss PAI Triggers and Notifications

The committee discussed changes to revise the Emergency Procedures (EP) web app’s language around PAI triggers to reduce the possibility of users mistakenly believing a PAI is in effect.

Rather than simply specifying that an active PAI trigger is in effect, the app would state a potential trigger has been activated and point users to the Data Miner page of PJM’s website, which holds the “data of record” on when PAIs are and have been in place. References to PAIs also would be removed from EP email notifications sent to those who have enrolled.

PJM’s Chidi Ofoegbu said the aim is to have the changes implemented in October, but no firm date has been selected.

Several stakeholders argued the changes do not go far enough and would leave it up to individuals to delve into apps they are unfamiliar with to determine whether generators face penalties in real time.

Voltage-reduction Action Test Results

A test of PJM’s voltage-reduction action capability conducted on Aug. 14 yielded a little over half the load relief expected and demonstrated a need for additional reactive capability.

The test was expected to bring load down by 1.3%, which amounted to 1,852 MW when it began at 2 p.m. A reduction of about 1 GW was seen during the test, about 0.7% of load. Generator reactive capability fell during the duration of the half-hour test by 2,824 MVAR.

Hatch said there was strong communication between PJM and transmission owners throughout the test, and both continue to see value in conducting them twice a year. An additional TO also has communicated to PJM its interest in joining future tests.

Regular tests of voltage-reduction capability were among the recommendations PJM made following December 2022’s Winter Storm Elliott, during which the RTO was on the brink of implementing the first reduction action since the 2013/14 polar vortex. The first biennial test was conducted in August 2024. (See “PJM Conducts Voltage-reduction Test,” PJM OC Briefs: Sept. 12, 2024.)

Preliminary 2026 Capital Project Budget

PJM’s Jim Snow presented the RTO’s preliminary $65 million capital budget for 2026, which includes the purchase of two properties on the same block as its Audubon, Pa., headquarters. The budget is approved by PJM’s Board of Managers with input from the membership and Finance Committee.

The funding request is a $15 million increase over the 2025 spending forecast, which itself was an uptick from an average spending of about $40.3 million between 2019 and 2024. The preliminary budget is composed of $21 million for application replacements, $20 million for facilities and technology infrastructure, $19 million for current applications and system reliability, $4 million for interregional coordination, and $1 million for new products and services.

The purchase of 955 and 975 Jefferson Ave. in Audubon falls under facilities and technology infrastructure, which is increasing from $8 million of spending expected in 2025 to $20 million in the proposal. The category also includes replacing obsolete network and server hardware, as well as updating cybersecurity monitoring software.

Snow said the building purchases are likely to occur in the first half of 2026, depending on whether talks with the property owners are successful.

Application spending, which is flat from 2025, includes a new short-term load forecast model, replacing “critical” out-of-support software used in weekly and monthly settlements and continuation of the multiyear Next Generation Markets Systems project to upgrade the market clearing engine.

Snow said much of the current applications and system reliability spending is for multiyear projects, such as overhauling the Dispatcher Application and Reporting Tool.

Staff deferred requesting $3.8 million for optimizing the modeling of combined cycle generators in the budget, as well as $1.3 million for improvements to the Energy Management System and an additional $1.3 million for technology upgrades.

August Operating Metrics

PJM experienced an average hourly load forecast error of 1.37% in August and an average peak forecast error of 1.80%, according to an RTO presentation.

There were four days where over-forecasting exceeded the RTO’s 3% peak load error benchmark on Aug. 1, 6, 20 and 21. The first three were attributed to actual temperatures coming in lower than expected, while the 6.92% peak error on Aug. 21 was from “excessive temperature error” across several zones.

The month saw three spin events, one Energy Emergency Alert level 2 event, three pre-emergency load management reduction actions, one emergency load management reduction action, two high system voltage actions, two hot weather alerts and 25 post-contingency load relief warnings. Five shortage cases were approved, with three falling on Aug. 14 and two the following day because of ramping interchange, solar output falling faster in the evening than the load ramp and combustion turbines not coming online as scheduled.

The three spin events each fell below the 10-minute duration PJM uses to determine when it may back down a 30% adder on the synchronized and primary reserve requirement. Performance must be above 75% for the adder to be reduced by 10% and a larger reduction is possible if performance is higher. (See PJM OC Briefs: March 6, 2025.)

An Aug. 6 spin event had a 1,679-MW generation assignment, 69% of which responded, and 83 MW DR assignment, with a 42% response.

An Aug. 14 event had 2,855 MW of generation assigned, with 51% responding, and 538 MW of DR, 74% of which responded. An event the next day had 3,245 MW of generation assigned, 64% responding, and 454 MW of DR assigned, with 82% responding.

Cybersecurity Report

Delivering the monthly security report, PJM Director of Enterprise Information Security Jim Gluck highlighted a ransomware attack that used Anthropic’s Claude artificial intelligence software to target 17 organizations, including identifying network weaknesses, writing code used to bypass intrusion detection measures and obtaining individual credentials. Anthropic has published an article detailing how the attack was conducted and the guardrails it is developing to limit future potential, but Gluck said the use of AI continues to be a game of cat and mouse.

Gluck also recommended that stakeholders participate in a study researchers at the University of Pittsburgh are conducting to understand the barriers to additional cybersecurity spending, with the goal of creating a set of recommendations and a policy guide.

PJM Preparing Alterations to Rejected CIR Transfer Proposal

PJM plans to modify and refile a proposal to revise how capacity interconnection rights (CIRs) can be transferred from a deactivating resource to a new unit after FERC rejected the tariff because of language that would have allowed developers to bypass the commercial operation date deadline (ER25-1128).

The proposal would create a nine-month process for PJM to conduct a replacement impact study on resources inheriting the CIRs from a deactivating unit and for an interconnection agreement to be offered. It would allow replacement resources to proceed through the expedited study process if minor network upgrades are identified and would not bar any resource class, thus allowing storage to receive CIRs. The revised tariff language will be brought to the Members Committee for endorsement Sept. 25. (See PJM Stakeholders Endorse Coalition Proposal on CIR Transfers.)

Stakeholders who supported the changes when the Planning Committee first endorsed the language in 2024 argued it would allow gas generators deactivating amid state clean energy policies to be replaced more quickly.

PJM Senior Manager of Interconnection Projects Jason Shoemaker told the PC that FERC signaled support for the overall proposal but identified two areas of concern: exempting resources with long development times from the COD requirement, and a one-time process for developers to request an indefinite delay for their CODs.

In its order rejecting the initial proposal Aug. 8, the commission faulted PJM for allowing developers to request a delay in transferring their CIRs without any time limit, which it said could allow resource owners to effectively withhold CIRs and create barriers to new entry. The commission said that undermines the RTO’s stated goal of allowing more resources to come online ahead of a capacity deficiency identified in the 2030 time frame.

“We find that PJM’s lack of a maximum time limit for the one-time option for an extension of a replacement generator resource’s commercial operation date regardless of cause renders PJM’s proposal unjust and unreasonable because it undermines the purpose of the generator replacement process,” the commission wrote. “That is, the main purpose of the generator replacement process is to avoid duplicative study costs and operational costs that otherwise would occur when the request to replace an existing generating facility must proceed through the interconnection study queue process, which will in turn avoid delaying the replacement of older resources with more efficient and cost-effective resources.”

The revised language would set the COD requirement at the greater of four years from when the developer submitted an application to construct a replacement resource, or three years from the requested deactivation date of the original resource.

Developers could request an alternative COD during the final agreement negotiation process, but they would have to demonstrate why the requirement should be shifted — akin to the milestone extensions permitted in the generation interconnection agreement process.

After the interconnection study is complete, developers could submit changes to the project to mitigate material adverse impacts and potentially reduce the network upgrades they are assigned. The submission would have to be made within 15 business days of receiving the study results and could be done only once. PJM would retool its analysis with the changes.

The commission also wrote that it saw the logic behind allowing generators with long development timelines some flexibility in their COD requirement but said the language could be ambiguous. While it did not cite that as a rationale for rejecting the proposal, FERC recommended that PJM include more specific language in any refiling.

“We also agree with PJM’s goal of offering replacement generation resources that face long lead times a certain degree of flexibility with respect to achieving commercial operation and agree that such resources ‘can make a significant contribution to meeting resource adequacy needs, at a time when PJM needs additional resources to maintain reliability,’” the commission wrote.

The COD exemption for resources with “industry-recognized significant construction time frames” was eliminated from the proposal.

Ontario Market Monitor Revamps Techniques for IESO Nodal Market

Ontario’s energy regulator is learning new ways to identify inefficiencies and malign behavior under IESO’s Market Renewal Program, which introduced LMPs and a financially binding day-ahead market.

The Ontario Energy Board said its Market Surveillance Panel (MSP) has developed “new tools and indicia” in response to IESO’s nodal market, which launched May 1. (See Ontario Nodal Market Nearing ‘Steady State’ After Nearly 4 Months.)

OEB said the MSP will continue to track “market participant conduct and the efficiency and competitiveness” under the new market. “However, the complexities of the renewed markets have increased relative to the legacy markets,” it said.

The MSP, which transferred from IESO to the OEB in 2005, has three members: Chair Ken Quesnelle, former vice chair of the OEB and former chair of the Electricity Distributors Association; Brian Rivard, an adjunct professor at the Richard Ivey School of Business at Western University and a principal at Charles River Associates and IESO’s former director of markets; and Darren Finkbeiner, IESO’s former director of rule compliance and market surveillance. The MSP is supported by OEB staff and uses data provided by IESO’s Market Assessment Unit.

The MSP’s previous recommendations have been adopted by both the OEB and IESO — including some of the changes implemented under Market Renewal. MSP reports also have led to action by the IESO’s Market Assessment and Compliance Division, resulting in settlement repayments and financial penalties.

New Market: Locational Marginal Prices and Single Clearing

Under Market Renewal, day-ahead market (DAM), pre-dispatch and real-time prices are calculated at about 1,000 LMP nodes, instead of Ontario-wide. With a financially binding DAM, there now is a single dispatch schedule.

Here are some of the other changes under the new market, and how the MSP plans to respond:

    • Congestion Management Settlement Credit (CMSC) payments: CMSC payments encouraged participants to follow dispatch during transmission constraints under the former two-schedule system. They were replaced by LMPs — which embed the cost of congestion — and make-whole payments (MWPs), which compensate for lost opportunity costs when IESO dispatches resources out-of-merit.
      • While continuing to use the highest-cost peaking natural gas generators as an initial screen, the MSP also will use statistical models to identify anomalous LMP differences not explained by losses or congestion. “This type of monitoring analysis will replace the monitoring of legacy CMSCs to assess potential market flaws or inappropriate conduct not explained by grid conditions,” OEB said.
      • The MSP will monitor large MWPs, as well as MWPs to individual market participants or for specific facilities, to identify anomalous results or market manipulation. A new MWP Anomaly Index will put MWP levels in perspective relative to resource margins in the day-ahead and real-time markets. The index is calculated as: MWP ÷ (Resource Revenues + MWP) x 100. “This metric will tend to filter out changes in the level of MWPs due to variations in fuel costs … as well as those due to the frequency with which particular types of units are committed, to better identify potential anomalies and changes in behavior,” OEB said.
    • Reserve Shortage Penalties: IESO now is using reserve shortage penalty prices (a maximum operating reserve area penalty price, a penalty price for 30-minute operating reserve and an area minimum operating reserve penalty price) to ensure that day-ahead, pre-dispatch and real-time calculation engines respect mandatory reserve requirements, that prices reflect those requirements, and to encourage market participants to meet their reliability obligations.
      • The MSP will review all applications of reserve shortage penalty prices to identify the causes of the shortages and potential anomalies in market design or inappropriate market conduct.
    • Operating Parameters: The renewed market requires non-quick-start gas generators, hydro and variable generation to submit additional data on their operating parameters.
      • The MSP will monitor changes to individual facility data for their effects on dispatch and economic efficiency. “Changes to this data may be part of a broader strategy by a market participant to inappropriately influence market outcomes, MWPs and prices to the benefit of the participant [at the expense] of other market participants and consumers,” OEB said.

IESO Market Power Mitigation

IESO introduced a three-pronged market power mitigation (MPM) scheme to prevent suppliers from market power due to their location on the transmission grid:

    • An ex-ante (before-the-fact) approach applied in the day-ahead, pre-dispatch and real-time scheduling processes to police the energy and operating reserve markets.
    • An ex-ante mitigation process to prevent market power in the settlement of make-whole payments.
    • An ex-post (after-the-fact) mitigation of market power to address physical withholding and economic withholding on uncompetitive interties.

OEB’s surveillance unit will evaluate the effectiveness of the MPM framework through its own three-part market power screen: a conduct test (for withholding activity); a material price impact test (determining whether the conduct of a market participant significantly impacted market prices), and a profitability test (whether the MP’s conduct benefited the participant).

Market Control Entities

IESO will use data from market control entities — companies that control generators and other market participants (dispatchable and price responsive loads, electricity storage resources, energy traders or virtual traders) — to assess physical withholding by examining in aggregate the offer quantities of resources that share a common MCE.

The MSP will incorporate the data in calculating structural measures of competition such as the Herfindahl–Hirschman Index and Residual Supplier Index.

OEB said the MSP will monitor persistent price differences between DAM and RT to ensure they are not a result of illiquid markets or gaming.

New Tool for IESO

To assess the effectiveness of the renewed markets and identify potential solutions to unintended outcomes, the IESO developed the Market Analysis and Simulation Toolset (MAST), which enables it to conduct “but-for” analyses of market outcomes through inputs into the market calculation engines.

OEB said the MSP also may use MAST in its assessment of the market’s efficiency in its annual State of the Market reports, as well as to analyze anomalous market outcomes and identify potential market flaws.

“In an upcoming State of the Market report, after sufficient data has been collected to permit such an analysis, the MSP intends to provide a comparison of the relative efficiency and competitiveness of the legacy markets to the renewed markets,” OEB said. “This analysis is not intended to be an audit of MRP at achieving its objectives. Instead, it is intended to offer insights into the overall efficiency implications of the changes, including where certain efficiencies may or may not have been realized and where improvements in design may be desirable.”

Around the Corner: The Long-Awaited Nuclear Renaissance Shows Signs of Promise, But Still has a Long Way to Go

Amid the growing push for new sources of power generation — especially from the data center sector — we have seen an extraordinary number of announcements concerning nuclear power. At this point, they are occurring almost weekly, something few would have anticipated just a few years ago. 

These announcements generally fall into one of three areas: rehabilitation of closed nuclear facilities, potential development of new large-scale facilities such as the AP 1000 technologies currently deployed across the country, and development and deployment of an entirely new class of smaller reactors commonly referred to as small modular reactors (SMRs) or modular nuclear reactors (MNRs). The buzz in the space is considerable, but there still are numerous hurdles to be overcome before we can declare a win for the much anticipated “nuclear renaissance.” 

Not Dead Yet

In recent years, numerous nuclear plants were struggling to survive, especially in competitive power markets where low-cost gas-fired and renewable plants were seriously denting their economics. Indeed, the economic outlook was so poor that five states (Connecticut, Illinois, New York, New Jersey and Ohio) threw their nuclear plants lifelines and created subsidy programs to keep 14 nuclear plants operating.  

Several other states, though, chose to let plants be taken out of service. The typical decommissioning process is to remove and store the fuel, dismantle the plants and decontaminate the sites. In fact, that process has been followed by dozens of sites over recent decades.

However, as forecast power demand has rapidly increased recently, several recently decommissioned sites are now being pressed back into service. These include the 837-MW Three Mile Island 1 in Pennsylvania that is slated to deliver power to Microsoft for 20 years, the 800-MW Palisades plant in Michigan and the 615-MW Duane Arnold facility in Iowa. And most recently, Holtec International, the owner of the 2,000-MW decommissioned Indian Point nuclear plant in New York, suggested the possibility of rehabilitating the facility for an estimated $10 billion. 

While these efforts eventually may bring back over 4,000 MW of capacity online, there may not be many other resurrection efforts to follow, since many of the other decommissioned plants are either too far along in the process or may not prove economically viable. 

An addition to this category might include the uncompleted V.C. Summer plant in South Carolina, which was abandoned in 2017 after burning through $9 billion of investment capital. That facility was thought to be dead until January 2025, when utility Santee Cooper issued a request for proposals seeking “to acquire and complete, or propose alternatives, for two partially constructed generating units at the VC Summer Nuclear Station.” In May, the utility said it had received responses to the RFP but offered few details.  

Revisiting Large Light Water Reactors

New nuclear power supply may come from the traditional light water reactors that have been employed by the U.S. power industry for many decades. For example, the proposed gargantuan 11,000-MW Fermi Project in Texas recently submitted an application to the NRC that includes four, 1,000-MW Westinghouse AP1000 nuclear reactors. (The last such units deployed were in the Vogtle plant in Georgia back in 2023, coming in more than seven years behind schedule and $17 billion over the original budget.) However, it appears that the new smaller and modular nuclear technologies may dominate this space. 

Smaller Cookie-cutter Modular Units

In recent years, SMR-related investments and project announcements have surged, with much of this coming from the data industry. Dozens of companies — from large and established energy players such as GE, Hitachi, Rolls Royce and Westinghouse to numerous startups — are vying for success in this industry. They typically distinguish themselves from the existing light water reactor technologies in terms of size and technology, with many boasting fail-safe designs.  

Models range in size from so-called “micro reactors” as small as 1 MW to larger units offering almost 500 MW of output. Many startups feature competing technologies that have not yet been tested commercially, and given the large number of contenders, many will fail commercially. But that hasn’t seemed to slow the sector of late. In fact, in the frothy SMR waters, just since mid-August the following commitments have been heralded:  

    • Tennessee Valley Authority announced a contract with developer ENTRA1 Energy for a 6,000-MW deployment of MNR startup NuScale’s 77-MW reactors, the only ones thus far to have received NRC approval for their design. 
    • Startup X-energy hailed a collaboration with Amazon, Korea Hydro & Nuclear Power and Doosan Enerbility “to accelerate the deployment of new Xe-100 advanced nuclear reactors in the United States,” with a stated goal of deploying more than 5,000 MW of new nuclear capacity across the U.S. by 2039, while mobilizing up to $50 billion in public and private investments.  
    • Data co-location giant Equinix announced three separate deals with different modular nuclear companies for nearly 775 MW of new capacity in the U.S. and Europe, with power to come from reactors ranging in size from just over 1 MW to 470 MW. 
    • Finally, the Utah Office of Energy Development (OED), TerraPower (the Bill-Gates-backed company) and Flagship Companies signed a memorandum of understanding “to explore the potential siting of a Natrium reactor and energy storage plant in Utah.” 

It’s increasingly looking like a new generation of nuclear reactors may become part of our energy future.

Big Data, Big Commitments

Much of the recent momentum is directly attributable to the data center companies that are hungry for power, while in many cases striving to maintain commitments to reduce associated carbon emissions. In addition to Equinix’s more recent announcements, it also had signed a deal to buy up to 500 MW of power from SMR startup Oklo, with a $25 million pre-payment for future power output and a right of first refusal for from 100 to 500 MW of power. 

Google also has been active. In May, it signed an agreement with nuclear project developer Elementi to commit early-stage development capital to support at least three projects that each would generate more than 600 MW. The company has the option to be a project off-taker once the facilities are commissioned (terms and locations were not specified). 

In October 2024, Google said it would financially support deployment of seven SMRs from startup Kairos Power that eventually would generate up to 500 MW of output, with a first unit operational by 2030 and additional reactors online within five years. Kairos already has started construction of a demonstration project in Oak Ridge, Tenn. 

For its part, Amazon has invested more than $500 million in SMRs, and took the anchor role in a $500 million funding round supporting SMR developer X-energy. And last fall, Oracle announced it intended to develop data centers powered by SMRs.  

More such announcements are likely to come as the data center industry appetite for new power supplies continues to grow. Data centers are not the only industries showing interest. Among others, utility Energy Northwest and materials science company Dow both have committed to projects using X-energy’s technology, with Dow already having designated a development site in Texas. 

Rare Bipartisan Support in Washington

While the promotion of many energy sources fall into red or blue camps, nuclear generally has managed to remain purple. In 2024, Congress passed the strongly bipartisan Accelerating Deployment of Versatile, Advanced Nuclear for Clean Energy (ADVANCE) Act, which specifically seeks to promote advanced reactor technologies. 

In addition, the U.S. Department of Energy has provided significant financial support, including a $900 million effort that began during the Biden administration to accelerate the development and deployment of SMRs. In August, DOE selected 11 advanced reactor projects for accelerated deployment, streamlined testing and fast-tracking toward commercialization. 

A Nuclear Renaissance Won’t Happen Unless Certain Conditions are Met

Major challenges remain to be addressed before we can proclaim the nuclear industry as reborn. The thorny nuclear waste issue remains to be solved. So does the issue of security. It’s one thing to guard the 50+ nuclear sites operating today and quite another to secure hundreds of them. There also are the siting challenges and the problem of convincing neighbors to accept these plants in their communities. Nuclear sites also will face the same interconnection challenges that have bedeviled any other generating assets connecting to the grid.  

Perhaps most critically, though, these new nuclear plants will need to be cost-competitive. Manufacturers will have to build the manufacturing facilities to make all the parts and entice enough firm orders to create the necessary economies of scale. It will not be enough for companies to build these new nuclear reactors in the single digits. The winners in this race likely will need to build dozens of them to get the costs down to where they can become competitive with other sources of generation.  

It’s one thing to do that with solar modules or batteries, where global supply chains wring out inefficiencies through production of literarily hundreds of millions of the devices. It’s quite another to create such efficiencies in a new industry, in which there are many competing companies and technologies.  

To succeed, the infant industry will have to migrate from one-off projects to a broad-based, factory-centered production approach, enjoying a large and predictable order book. It also will need to nurture the necessary talent to manufacture, site and operate the plants in the field. We’re not remotely there yet, but for fans of a nuclear renaissance, recent events offer encouraging signs.

CEC Awards $28M for New Battery Facility in Hayward

The California Energy Commission approved a $28 million grant to Electrochemistry Foundry to build and operate a battery fabrication and testing facility in Hayward, Calif. 

The 20,000-square-foot facility will be “shared-use” and able to produce 10,000 lithium-ion battery cells per year. 

California does not have open-access battery manufacturing facilities, the CEC said in the grant award. Without these types of facilities, startups face “long delays and steep cost barriers that cause many promising battery innovations — especially in underserved sectors like heavy-duty transportation, industrial electrification and stationary storage — to stall before reaching the market,” the agency said. 

Most shared battery testing facilities are thousands of miles away in the Midwest, South or East Coast, Electrochemistry Foundry representatives said. Building such facilities within a one-hour drive of people who use them is ideal and ensures maximum ease of access and collaboration, they said. 

“Early-stage startups cannot justify leasing their own dedicated facilities, and most startups currently can only access fractional lab space from biotech facilities, which are not well-suited for supporting battery and electrochemical companies,” Electrochemistry Foundry representatives said. 

However, Barry Broome, CEO of the Greater Sacramento Economic Council (GSEC), asked the CEC to defer approval of the item and require an outside audit of the award process that granted the project to Electrochemistry Foundry. 

GSEC founded Cal EPIC, a nonprofit that finished second in the CEC’s grant award process, behind Electrochemistry Foundry. GSEC is a public-private partnership that connects business and community leaders to build a regional economic development strategy that focuses on growth, sustainability, equity and competitiveness, the organization says on its website. 

“Given our engagement with the CEC and others during this grant process, we have serious concerns as to the fairness of the solicitation development and award decision and transparency of the communications and processes surrounding them,” Broome said in a Sept. 9 statement. 

“This [battery facility] is a critical asset to our community. … And, you know, in this era of transparency in government, we’re counting on our government to set the tone for that, since it’s been lost throughout the country,” Broome said at the CEC’s Sept. 10 business meeting. “This location has unique advantages that we thought were missed in the [grant award] scoring.” 

VGI Grants, REC Software Changes

At the meeting, the CEC also approved about $15.4 million in grants to nine entities related to Vehicle-Grid Integration (VGI) work. Grants included about $2.4 million to Rivian to build an alternating current bidirectional charging system and $2.7 million to Lucid Group to build an alternating current bidirectional onboard charging system. 

Also at the meeting, representatives of the Western Electricity Coordinating Council (WECC) told CEC commissioners they are working to find new software for the Western Renewable Energy Generation Information System (WREGIS), which tracks renewable energy certificates predominantly in the Western Interconnection. 

WREGIS operates using software provided by CleanCounts, but the organizations’ contract expires Dec. 31, 2027, and CleanCounts has chosen not to extend it, WECC staff said. The contract’s expiration has prompted reevaluation of how WREGIS’s future looks and how its services to users and programs can be enhanced, they said. 

To replace CleanCounts, WECC staff recommend building custom software for WREGIS. They also recommend separating WREGIS from WECC, which would allow the owners of WREGIS to focus solely on the program’s goals.

SPP Clears GI Queue Backlog, Ready for New Process

SPP says it has cleared its backlog of generator interconnection requests that dates back to 2018, paving the way for a transition to its “first-in-the-country” Consolidated Planning Process.

The grid operator said in a news release that the six study clusters through 2023 have all reached the restudy phase. Each request in the clusters has completed the two-part study phase and is either signing GI agreements, moving into GIA negotiations or undergoing a restudy, an SPP spokesperson told RTO Insider.

“SPP’s interconnection customers deserve an efficient study process to enable their proposed generator projects,” Jennifer Swierczek, the RTO’s manager of generation interconnection policy and study, said in a statement.

SPP said efficient interconnection studies are critical and give developers and utilities the cost certainty and regulatory approvals needed when energy demand is rising.

Staff have completed 24 cluster studies since 2022, analyzing 340 GW of generation — six times SPP’s peak load — and evaluating 1,652 projects through its definitive interconnection system impact studies (DISIS).

The work has resulted in 190 signed GIAs for more than 30 GW of generation. Another 20 GW of additional generation is expected to execute GIAs in the next 12 months, the RTO said.

According to SPP’s GI queue dashboard, 191 active requests from the backlog remain in the GI queue. The 2024 study cluster, which has not yet gone through DISIS, includes 345 requests for about 90 GW of capacity.

SPP began tackling the backlog in 2022 with the 2018 cluster. The queue contained 1,139 active requests for 221 GW of capacity at the time; it now has 552 active requests for 130.5 GW of capacity. (See “SPP Modifies GI Backlog Process,” SPP Markets & Operations Policy Committee Briefs: Oct. 15-16, 2024.)

The grid operator’s board, state regulators and members approved the CPP in July and August. It replaces the current sequential planning and GI studies that have led to an average of six-year wait times before resources go into service.

The new process includes a long-term 20-year study and an annual 10-year assessment, aligning system modeling, planning assumptions and cost allocation across load and generation needs. The CPP-10 includes a GI capability study, a GI decision point and a regional transmission assessment that recommends projects for construction. The CPP-20 establishes a 20-year regional vision. (See SPP Celebrates Novel Consolidated Planning Process.)

Staff will be able to use the process once it has FERC approval, significantly accelerating the addition of new generating resources to the grid. SPP has said it plans to file the tariff change with the commission by October and will request an effective date of March 1, 2026.

Full implementation will begin in 2027, and the first CPP portfolios are expected to be delivered in 2028. Transitional work will bridge the gap between the CPP framework and the current study process for the 2026 and 2027 assessments.

PJM Stakeholders Endorse Expansion of Provisional Interconnection Service

The Planning Committee voted to endorse a PJM quick fix proposal to expand provisional interconnection service to allow resources that are not fully deliverable to enter service as energy-only resources. The quick fix process allows an issue charge and corresponding proposal to be voted on concurrently. (See “1st Read on Expanded Provisional Interconnection Service,” PJM MRC/MC Briefs: Aug. 20, 2025.)

PJM Director of Interconnection Planning Donnie Bielak said the proposal is intended to allow resources to begin operations while their requisite network upgrades are proceeding, making more energy available to dispatchers going into emergency conditions. As of the Sept. 9 PC meeting, he said more emergency conditions had been declared in 2025 than in the previous decade combined, a trend he said is likely to continue with rising load growth and limited new generation.

Provisional interconnection service allows a planned resource to enter service before the network upgrades assigned to it have been completed only if an interim deliverability study determines it can reach its full output without triggering transmission violations. The proposal would loosen that standard to grant provisional status if a resource can deliver part of its installed capacity, which would be documented in an operational guide to inform dispatchers about how the unit can be operated. It targets provisional service requests for the 2026/27 delivery year; any agreements it awards would need to be renewed by developers with annual interim deliverability studies until the resource enters full service.

The quick fix proposal focuses on expanding the pathway for developers to apply, and pay, for PJM to study a planned resource for provisional service. A separate issue charge endorsed by the PC will explore a process for PJM to proactively identify projects that might quality for provisional service without slowing the overall interconnection study process.

The longer-term issue charge envisions a 10-month stakeholder effort charging the Interconnection Process Subcommittee with identifying possible changes to the tariff and business manuals. The out-of-scope section includes generation that does not fall under FERC jurisdiction, the requirements for resources to participate in the capacity market, and changes to the interconnection process not pertaining to provisional service.

Bielak said the proposed manual language was amended after the August first read to state that PJM will publish the provisional interconnection service offered to resources to allow market participants to have the same insight on the status of the transmission grid. Additional language was added around how the resources would be dispatched to clarify they won’t receive special treatment.

“The existing procedures under these operations will prevail, and these will be treated like any other energy-only resource,” Bielak told the PC.

Paul Sotkiewicz, president of E-Cubed Policy Associates, argued PJM should post all requests for provisional service, stating it could inform market participants’ hedging strategies. He said the manual language detailing the information about service requests and awards PJM would post should explicitly specify attributes like the output resource owners seek to inject.

Bielak questioned the value that information would provide and said he prefers more generic language to avoid situations where changes to the posting requirements for the overall interconnection process might fall out of sync with the provisional pathway.

Gregory Pakela, manager of regulatory affairs for DTE Energy Trading, said the data Bielak presented shows the bulk of emergency procedures have been initiated during the summer, suggesting reliability risk corresponds to load peaks during heat waves more than PJM’s winter-skewed risk modeling would suggest.

“We have to treat models as tools, but the interpretation of those models is almost more of an art,” he said.

ISO-NE Faces Criticism over Accountability, DER Policy at Public Meeting

Several panelists and public commenters at the quarterly meeting of the ISO-NE Consumer Liaison Group criticized the RTO over its record on accountability and accessibility, as well as its policy related to distributed energy resources.

The tenor of CLG meetings has been critical of ISO-NE since a coalition of climate activists took control of the group’s coordinating committee in 2022. (See Climate Activists Take Over Small Piece of ISO-NE.) Many of the same themes and critiques from past CLG meetings resurfaced as the group met in Manchester, N.H., on Sept. 11 for its third-quarter meeting.

Marla Marcum, an activist associated with the climate group No Coal No Gas, criticized the closed nature of NEPOOL stakeholder proceedings. She said grassroots climate activists are interested in engaging in discussions around ISO-NE’s ongoing overhaul of its capacity market but are prevented from meaningfully participating in discussions because they are not members of NEPOOL. (See ISO-NE Kicks off Talks on Accreditation, Seasonal Capacity Changes),

Responding to the criticism, Anne George, ISO-NE’s chief external affairs and communications officer, said all materials and minutes from stakeholder meetings are posted publicly, and members of the public are welcome to submit input for review by the RTO’s market development team.

“The ability for us to throw our comments into the whirlwind, no matter how good they are, is not the same as being able to meaningfully participate in this process,” Marcum responded.

Meanwhile, New Hampshire Consumer Advocate Don Kreis repeated his past criticisms of the RTO for being incorporated in Delaware, arguing that it would be more accountable to ratepayers in the region if it was incorporated in New England.

The meeting also featured a panel on how ISO-NE can help address energy affordability. Several panelists urged the RTO to do more to help demand response and DERs participate in its markets.

Allison Bates Wannop, a lawyer and DER advocate with experience working in all U.S. RTOs, said she has “found ISO-NE to have a preference for not enabling distributed energy resources.”

While she praised the work of ISO-NE staff, she said the RTO generally appears “distrustful” of DER aggregators and has been overly conservative in its compliance with FERC Order 2222, which requires RTOs to lower barriers to DER aggregators to participate in wholesale markets.

Bates Wannop highlighted FERC Commissioner Allison Clements’ concurrence on FERC’s ruling on ISO-NE’s original Order 2222 compliance proposal, in which Clements strongly criticized the RTO for putting forward “a proposal that was almost universally panned by prospective market participants seeking to integrate behind-the-meter resources into its markets.” (See FERC Gives ISO-NE Homework on Order 2222.)

Clements wrote in her concurrence that ISO-NE’s submetering proposal for DER aggregations is significantly more burdensome for aggregators than the proposals of other RTOs, adding that ISO-NE’s unique circumstances do not “necessarily provide an excuse for not adopting an approach similarly to those successfully pursued elsewhere.”

Also during the panel, Kreis asked speakers about a recently passed bill directing the New Hampshire Department of Energy to study the possibility of withdrawing from ISO-NE. Multiple speakers expressed hope that the study would allow for a constructive look at improving the RTO.

However, several speakers expressed skepticism about the viability of leaving ISO-NE, along with the benefits this move would have for New Hampshire consumers.

Henry Herndon, acting general manager of the Community Power Coalition of New Hampshire, said the bill poses an “interesting opportunity to ask questions.”

Bates Wannop said that “while I don’t think New Hampshire should leave ISO-NE, I think constantly asking the question how it can be reformed is important.”

Imagining an Ideal RTO

Also at the CLG meeting, Ari Peskoe, director of the Electricity Law Initiative at Harvard Law School, delivered a keynote speech centered around imagining an ideal grid operator for the region, unincumbered by history, compromises and agreements that have led to the current structures and roles of ISO-NE and NEPOOL.

“ISO-NE’s governance is tied to the peculiar history of New England utilities, rather than any particular attributes,” he said.

Peskoe noted that, due to the history of ISO-NE’s formation, New England transmission owners participate in ISO-NE voluntarily and retain filing rights over the revenue requirements for their own system. Meanwhile, candidates for the ISO-NE board of directors are nominated by a committee made up of current board members and NEPOOL participants and are approved by the NEPOOL Participants Committee and the board.

If the region was starting from scratch, Peskoe said, it still would be beneficial to have some form of nonprofit regional entity to ensure cost and operational efficiency across the region’s grid, but he would like to see greater independence from market participants and a stronger emphasis on innovation.

While the hypothetical, redesigned RTO would remain a non-regulatory independent entity, Peskoe said the states could take on a larger role. He floated the idea of allowing each governor to nominate one non-state employee candidate to the board.
