SPP Strategic Planning Committee Briefs: July 17, 2025

SPP’s Strategic Planning Committee unanimously endorsed RTO staff’s comprehensive approach to accelerate transmission capability, directing them and SPP’s working groups to prioritize the development of policies for all short-, mid- and long-term initiatives. 

Time is running short, Casey Cathey, SPP vice president of engineering, said during the July 17 meeting. Staff are producing solutions for the 2025 Integrated Transmission Planning assessment, which will be shared with stakeholders in October.  

The ITP portfolio is expected to be another large one, possibly double that of the record 2024 assessment. That one produced 89 projects expected to cost $7.65 billion. (See SPP Stakeholders Endorse Record $7.65B Tx Plan.) 

“We still have some work to do to solidify and optimize that total final portfolio, but we’re still looking at a multibillion-dollar portfolio,” Cathey told the SPC. “It may be in the realm of $15 billion. And so there is a notion that anything that we can do between now and November, we should probably do, recognizing that expedited revision requests and all of the things moving so fast this year has been problematic.” 

Noted teen philosopher Ferris Bueller said, “Life moves pretty fast. If you don’t stop and look around once in a while, you could miss it.” 

But Cathey can’t afford to stop and look around. 

“We have to accelerate everything. We need to accelerate load. We need to accelerate generation. And so today’s topic is accelerating all things transmission,” he said. 

Cathey said while SPP has added about $1 billion in transmission annually over the last decade, the evolving generation mix and growing reliability needs demand a faster and more targeted response.  

Staff have proposed a multiphase strategy that speeds up transmission capability by: accelerating issuance of notifications to construct and timelines for selecting transmission owners under the competitive process; increasing deployment of near-term solutions; improving the efficiency of project completions; and addressing a diverse range of stakeholder perspectives. 

Gaining and obtaining the SPC’s endorsement and guidance was the first step. 

Christy Walsh, with the Natural Resources Defense Council, said she loved the focus on capacity. 

“We need to build more transmission. We need more. We need to upgrade the biggest existing system as much as we can,” she said. “We keep hearing it’s going to take three to five years to build transmission. But we’re also hearing we need capacity now for the new loads and whatnot. If we can squeeze more capacity out of the existing system … we should be doing that now while we’re waiting the optimistic three to five years for the new transmission, and that’s three to five years on top of the planning process.” 

Cathey agreed, saying staff are evaluating internal procedural barriers and coordinating with state and federal agencies to streamline permitting and construction efforts. The upcoming work will incorporate the strategies into long-range planning efforts and potentially shape future policy proposals. 

Forecasting Mitigation Process OK’d

The committee unanimously endorsed its Load Forecasting Task Force’s proposed strategy to mitigate forecast risk in the SPP footprint and its impact on system planning. 

The team has proposed improving consistency between forecasts used for resource adequacy and transmission planning purposes to address growing concern about under-forecasting load due to rapid economic growth, electrification trends and data center expansions. It says traditional forecasting methods may not fully capture emerging demand risks. 

Oklahoma Gas & Electric’s Brad Cochran, the task force’s chair, said the group has been meeting for a year. During that time, it had several conversations with other grid operators about their practices. 

“What we were finding through discussions is there’s variability and timing of when entities are completing their forecasts and when they’re updating them,” he said. “We’ve talked extensively … about large loads and how fast they’re coming. Those forecasts change and those numbers change often, so aligning those two so you have similar information in both of these planning processes is a big deal.” 

The team recommended continuing to use separate load-responsible entity forecasts for RA and Integrated Transmission Planning (ITP) but require an update to the ITP forecast during the RA submittal window. It also advocated that SPP assess whether to develop in-house forecasting expertise, but not conduct forecasts for individual LREs. 

“Because of the diverse footprint of SPP and the diverse membership at this time, the task force didn’t think that it makes sense for SPP to develop these forecasts for all 60-plus LREs,” Cochran said.  

He suggested SPP have some level of expertise and knowledge to give it “the ability to kind of build and evolve over time and look at these forecasts and communication.” 

STRP Task Force Created

The SPC agreed to form a task force to help develop guidelines and a framework for reforming the process for considering short-term reliability projects (STRPs). 

Irene Dimitry, an independent member of SPP’s Board of Directors, will chair the task force, which will report to the SPC. The effort comes after several attempts by staff resulted in a framework that she said was “too prescriptive.” 

“Given our role as independent board members, we need the ability to each apply our own judgment in making decisions about what’s best for SPP and its members and all the customers that we serve,” she said. 

SPP CEO Lanny Nickell said the focus for the task force should be, “How do we make it faster?” It has a January 2026 deadline for delivering meaningful plans to the SPC. 

“Ultimately, we need to do whatever is needed to produce reliability upgrades, to produce economic value and optimize all of that to consumers in the region,” he said. “We just need to make sure we recognize the fact that speed is of the essence, particularly if there’s a reliability need that’s been addressed by any upgrade.” 

SPP’s tariff defines STRPs as upgrades that meet the criteria for competitive projects but are needed in three years or less to address “identified reliability violations.” In that case, STRPs are not considered competitive upgrades under the tariff and are awarded to the incumbent transmission owner. 

SPC Increases Membership

The Corporate Governance Committee approved 11 nominations to the SPC, raising the committee’s sector membership to match that of the 23-person Members Committee. The nominations result from an April change to the bylaws. The SPP board will vote on the nominations during its August meeting. 

The new members are:  

Nick Abraham, ITC Great Plains; Rebecca Atkins, Missouri Joint Municipal EUC; Jarred Cooley, SPS/Xcel Energy; Mark Foreman, Tenaska Power Services; Steve Gaw, Advanced Power Alliance; Christopher Matos, Google; Kevin Noblet, Kansas Electric Power Cooperative; Robert Pick, Nebraska Public Power District; Sarah Ruen, Tri-State Generation & Transmission; Emily Shuart, OG&E; Christy Walsh, Natural Resources Defense Council. 

SPP has since announced Shuart will join SPP in September as senior director of external affairs and stakeholder relations. (See SPP Adds OG&E’s Shuart to External Affairs Leadership.) 

Senate Hearing Examines Return of Electricity Demand Growth

The return of electricity demand growth is a reality embraced by both political parties, but a Senate Energy and Natural Resources Committee hearing on July 23 highlighted their differences on how to address it.

“Here’s the real problem: We have spent much of the last 20 years shutting down the generation that can actually meet that demand,” committee Chair Mike Lee (R-Utah) said. “Coal plants retire, nuclear blocked, natural gas tied up in endless litigation; and we replaced a lot of that capacity with wind, solar and batteries, resources that by design don’t work all the time.”

The growth being driven by artificial intelligence and data centers, electrification and resurging domestic manufacturing will require changes to how energy infrastructure is permitted and built, Ranking Member Martin Heinrich (D-N.M.) said.

“No single business or technical workaround can substitute for a coordinated, modern, responsive grid,” Heinrich said. “Fortunately, we sit on the committee that can help make that happen. The urgency isn’t just about maintaining our edge in AI innovation; it’s about affordability.”

The recently passed reconciliation bill cut tax credits for the kind of energy resources that can be most quickly deployed — solar and wind, which Heinrich said would raise nationwide annual energy costs by $16 billion by 2030 and $33 billion by 2035.

“And the president’s tariffs are driving up equipment costs, raising the cost of all energy generation resources — all of them,” he added. “This is leading directly to Americans spending more on their utility bills.”

Lee pushed back on criticism about Republicans using reconciliation and relying on party-line votes to cut renewables subsidies in the recently passed “One Big Beautiful Bill Act,” reversing policies Democrats had enacted three years earlier using the same legislative tactic.

“The Inflation Reduction Act turbocharged subsidies for wind and solar,” Lee said. “And those subsidies are distorting energy investment, because the subsidies can offset more than 50% of the project’s costs — a significant amount that ends up being borne by the U.S. government and the U.S. taxpayer.”

On top of that, he added, those intermittent resources need to be balanced with energy storage or natural gas peaker plants, which add to the costs.

Huntsman Corp. CEO Peter Huntsman agreed, pinning the blame for the decline in its chemical industry on its net-zero policies.

“I’ve experienced this firsthand as our company has laid off thousands of employees in Europe,” Huntsman said. “Facilities that were globally competitive just a few years ago have been closed and are no longer operating due to ruinous and unrealistic net-zero and decarbonization policies and the failed ideas that you can power a modern economy without developing oil and gas resources.”

No AI Leadership Without Power

Jeff Tench, executive vice president at Vantage Data Centers, offered the perspective of his industry, saying that, just five years ago, a data center with 30 MW of power demand would’ve been considered “large.” Now, 100 MW is a starting point, and some customers are asking for 1 GW or more for data centers used to support artificial intelligence, he said.

“We cannot get the amount of electricity we need in the time frame to build our data centers,” Tench said. “Without electrical power, it is not possible to build digital infrastructure — the infrastructure that supports AI data centers. Transmission lines and generation facilities must scale rapidly if the U.S. is to remain the global leader in AI innovation. We are asking for your leadership to drive a more modernized policy framework that reflects today’s growth, aligns with investment timelines and ensures that the power system is ready when and where it is needed.”

Interconnection timelines for new generation and new large loads are too slow, the transmission grid needs to be upgraded to support the new demands, and permitting must be improved to ensure the U.S. can lead in AI development, he added.

“The United States is looking at an AI era that is not coming, but is here,” Tench said. “We have the capital, we have the customers and the talent, but we will not lead if we cannot power it.”

Power demand growth is sudden and challenging to meet, and it is contributing to affordability issues around the country, said Rob Gramlich, president of Grid Strategies. While acknowledging the need for more generation, Gramlich focused on transmission first because the federal government has more authority over its development.

“It has the highest impact,” Gramlich said. “It’s the great integrator of all resources. It may seem like it’s a renewable energy piece of infrastructure, but that’s just because over the last five years, that’s all anybody was trying to connect to the grid.

“Right now, we’re seeing a lot of other things trying to connect to the grid, including Jeff’s data centers and data centers around the country, other large loads, manufacturing and other types of generation. And whether it’s nuclear, [carbon capture and sequestration], other types of generation — guess what? It’s going to face that same constrained grid.”

Building new lines can take time, but grid-enhancing technologies and advanced conductors can be deployed more rapidly to get more out of existing infrastructure, Gramlich said. The industry also should keep considering building larger 765-kV lines, which are cheaper compared with building multiple lines to meet the same need, Gramlich said.

“We do need firm power to meet peak loads,” Gramlich said. “Resources provide varying levels of contributions to meeting peak loads. Nuclear has the highest contribution at 95%, but we’re not able to get much more very soon. Gas CTs, at least according to PJM, are around 60% in terms of their ability to serve peak loads. Combined cycle is a little higher in the 70s. Offshore wind is actually 69%.

“And so none of these resources are perfect, but the point is, when you put them all together on the integrated grid, that’s how you get nearly 100% reliability of the power system.”

N.Y. Considers New Fossil Generation as Renewables Lag

As it updates its energy plan to reflect new challenges to decarbonization, New York is contemplating what until recently seemed improbable, or even unthinkable: new fossil-fired generation. 

The state Energy Planning Board voted July 23 to publish the draft 2025 update of the state Energy Plan after 10 months of deliberations. A series of hearings across the state is scheduled to gather input on the draft. 

Further updates and revisions to the draft are expected as it approaches finalization toward the end of this year and the effects of federal policy changes become clear. 

The board’s chair — Doreen Harris, CEO of the New York State Energy Research and Development Authority — told RTO Insider that the huge shifts in federal policy over the past six months created uncertainty to a degree that required the board to present a range of scenarios in the draft. She said federal actions over just the past few weeks may have rendered some of those scenarios overly optimistic. 

The Trump administration is actively moving to thwart energy efficiency and clean energy initiatives such as those New York has worked more than a decade to build. Meanwhile, the recently enacted reconciliation bill, the One Big Beautiful Bill Act, eliminates federal subsidies that states were counting on to incentivize renewables development and shifts billions of dollars in federal spending obligations to state governments, thus limiting whatever inclination states had to subsidize renewables on their own. 

As such, New York is contemplating strategy shifts on multiple fronts with the draft update. 

Ambition vs. Results

New York has had mixed results in expanding its renewables portfolio and shrinking its carbon footprint. 

The Climate Leadership and Community Protection Act — New York’s landmark 2019 climate law — mandates 70% renewable energy and a 40% reduction in greenhouse gas emissions, as well as 100% zero-emission energy by 2040. 

But officials have acknowledged the state is likely to miss the two 2030 goals, possibly by a wide margin: GHG emissions were down only 9.3% as of 2022, and renewables accounted for only 27% in 2023. 

The draft update acknowledges the challenges facing the 2040 zero-emissions energy goal as well. Given the 23% increase in peak demand and 26% increase in annual demand expected by 2040, the draft emphasizes the importance of not falling further behind on generation capacity. 

One scenario envisions current-day nuclear and hydro assets continuing to play a key role in the state grid in 2040, joined by 35 GW of solar; 9 GW each of storage, onshore wind and offshore wind; and 16 GW of green hydrogen combustion. 

Any of those targets could be a challenge in the current environment, but hydrogen stands out as a leap of faith. 

The draft immediately acknowledges the technical challenges of generating huge quantities of hydrogen in an ecologically and economically sound manner. And it acknowledges that hydrogen or other “clean firm” technologies critical to this planning process are not yet scalable. 

So the draft looks at fossil fuel as indispensable for some time to come. Natural gas and petroleum will be diminished but still important energy resources in New York in 2040, the draft says, and fossil generation will remain essential to grid reliability. 

But a quarter of the state’s combustion generation capacity will be at retirement age as soon as 2028, so the state will need to be strategic about the pace of combustion unit retirements, the draft warns, and will need to consider whether new or repowered fossil-fuel generation is necessary. 

Harris said the state’s energy planning process has been faced with moving variables since President Donald Trump began his second term, and she said some of the scenarios laid out in the draft plan are based on factors and assumptions that recently became outdated.

“If anything, the reconciliation bill may have rendered even that planning case a bit optimistic from the perspective of renewable deployment in particular,” she said. 

NYSERDA’s senior vice president for policy, analysis and research, Carl Mas, said the language in the draft about new fossil generation is intentionally broad because there is such a broad range of possible outcomes as New York navigates state and federal economic and policy factors. 

But there are scenarios under which the state — which had sought to phase out fossil fuel generation in the 2030s —would instead seek construction of new fossil generation or retrofits to make older facilities cleaner and more efficient. 

“With the load growth that we’re seeing, we feel like we have to remain flexible,” Mas said. “There’s extreme amounts of uncertainty, but we have a very old fleet, and we have a growing load and substantial new headwinds that we didn’t have five or six years ago.” 

This does not alter the state’s commitment to renewables and decarbonization, Harris and Mas said. It recognizes that the plan for carrying out that commitment may need to be modified to maintain reliability. 

Tough Decisions

New York has a number of hard choices to make with its energy portfolio, and the draft update of the plan lays out some of the potential decision-making pathways in a rapidly evolving landscape. But it will not make the decisions easier. 

Renewables advocates have been unhappy about the state ratcheting back initiatives that have become untenable or expensive, and about the slow pace at which the New York Power Authority is starting its role as a renewables developer. Any move to authorize major new fossil infrastructure is likely to go over just as badly. 

Meanwhile, New York must decide whether to continue to subsidize the nuclear power plants that supply 22% of the state’s total electricity and 42% of its emissions-free electricity. Over the past seven fiscal years, this zero-emission credit program has consumed $3.73 billion gathered from surcharges on electric bills. 

The draft plan highlights the importance of the ZEC program, but it also states bluntly that “it is not feasible to continue increasing the number and scale of programs that electric ratepayers need to fund.” 

Another challenge: New York’s renewable energy pipeline — partly rebuilt after mass cancellations in 2023 — faces a new round of cancellations because of the impending end of federal tax credits under the reconciliation bill. 

“We have literally seen the federal government’s action result in tens of billions of dollars of impact on New Yorkers with respect to clean energy deployment costs,” Harris said. 

There is a wave of collateral damage beyond the tax credits, she said, as the industries and workforce that were growing in the clean energy sector retract and retreat. 

Harris added, though, that renewable energy is not expected to halt; the question is how much it will slow. 

“So this energy plan is taking into account the realities of having those tools impacted,” Harris said. 

Simultaneous Goals

The draft plan’s summary alone stretches 80 pages and reminds the reader why governmental processes sometimes move so slowly: It is filled with parallel and secondary goals that rope in a massive cast of stakeholders and competing interests. 

The draft suggests that as New York is reducing its carbon footprint and keeping its grid reliable, it should upgrade one of the oldest housing stocks in the U.S.; move to 100% zero-emission vehicle sales; reduce negative impacts on disadvantaged communities and actively steer positive impacts toward them; bolster organized labor; help poorer New Yorkers cut their energy costs; craft a more cohesive energy planning process; support research and development; build at least 1 GW of nuclear capacity; develop the energy workforce; lead the country in battery energy storage safety; maintain reliable gas transmission networks that can meet peak demand; consider wholesale electricity market reforms; and integrate renewables into the land-planning practices of often oppositional local governments. 

And it wants to do all of this affordably. 

“These are all goals that the state can meet without sacrificing one for another,” the draft says. 

It estimates that some of the scenarios would raise energy costs more than 35% by 2040. That is expected to be offset to some extent by lower health care costs and other societal benefits, but it would be a lot of money on top of already high rates. Heavy investment is needed under any scenario because of the age of existing transmission and generation infrastructure and the increased demands expected to be placed on them. 

But any embrace of new or rebuilt natural gas-fired generation would be a bitter pill to swallow for clean energy advocates. 

Marguerite Wells, executive director of the Alliance for Clean Energy New York, avoided the words “natural gas” in a statement but made the trade group’s priority clear: “Electric demand is rising, and legacy generating sources are aging. It’s patently obvious that renewable sources are going to be the fastest and lowest-cost method of bringing new power onto the grid.” 

ACE NY looks forward to commenting on the draft, she said, and working with the state to identify the inefficiencies and road blocks that are delaying renewables. 

State policy not long ago favored natural gas as the preferred alternative to coal and oil. 

The 2015 update of the State Energy Plan discussed New York’s ambitions for, and early steps with, renewables. But it also said, “Economic, operational and environmental advantages make natural gas the current fuel of choice for new and replacement generation in New York.” 

The 2019 climate law canceled that line of thought. But there was always going to be an off-ramp in case the vision did not come together as hoped. 

In the 2022 Scoping Plan it prepared for the law, the state Climate Action Council said, “The effectiveness of programs and policies should be continually evaluated and changed if renewable energy is not being deployed at the pace necessary to achieve the requirements on time.” 

The July 23 vote to publish the draft set in advance the process for such a potential change. 

Jackie Bray, commissioner of the Division of Homeland Security and Emergency Services and a member of the Energy Planning Board, said she was glad alternate scenarios were included in the draft in case the preferred scenario becomes impossible. 

There can be a tendency in this type of planning process, she said, for well-meaning leaders to continually add objectives to a blueprint on the assumption that there is time over the next decade to figure out how to reach those objectives. 

“Make sure that we are being realistic about what we can deliver and what we must deliver,” Bray urged listeners. 

NextEra Energy Puts Brave Face on Renewables’ Prospects

The nation’s largest renewable energy developer continues to present renewables as a bridge to the grid of the future and fashion itself as an “all-of-the-above” company in an optimal position to build that bridge.

But NextEra Energy’s July 23 financial report came on the heels of potentially major roadblocks for wind and solar development being erected by the federal government.

The company’s stock price took a hit in trading later in the day, despite solid second-quarter financials with year-over-year growth in revenue, earnings and order backlog.

Component company NextEra Energy Resources added more than 1 GW of commitments from hyperscalers to its backlog during the quarter, raising its total existing and planned service for data center and technology customers to more than 10.5 GW.

Its overall backlog is nearly 30 GW, the majority of it wind and solar generation, which is in a race to start or finish construction in time to qualify for sunsetting federal tax credits.

Tariffs, executive orders and agency rulemaking add uncertainty to the company’s strategizing, NextEra CEO John Ketchum said during a conference call with financial analysts.

“While there are risks to be managed, we believe there also are significant opportunities, given the steps we’ve taken to prepare for this moment, as we expect a natural pull forward of demand,” he said. “We are in a constant state of construction.”

No company is immune to all risks, Ketchum said, but NextEra has proved repeatedly it can navigate challenges.

He repeated a variation of the message that the renewables sector began broadcasting the day after Election Day 2024: America needs us.

That message seems not to have resonated with enough decision makers, given the details of the One Big Beautiful Bill Act that target wind and solar development.

But the company views OBBBA as a rule change, not a sunset or a cliff. “Tough, but constructive,” Ketchum called it.

“We are firmly aligned with the administration’s goal to unleash American energy dominance, and to do so, we need all of the electrons we can get on the grid. There’s truly no time to wait,” Ketchum said.

“As I’ve said many times, we’re going to need all forms of energy to meet this moment. New gas and nuclear are on the way and will be critical to meeting demand over the long term. Renewables and storage can bridge the gap and will play an important role in an all-of-the-above future.”

Ketchum said the leadership believes NextEra has begun construction of enough projects to reach its development expectations through 2029. They cannot, however, make any guarantees.

He added that if smaller companies not as well prepared as NextEra are unable to move forward in this environment, there would be opportunity for NextEra to pick up their projects and move them to completion.

Turning to the Duane Arnold nuclear plant in Iowa, Ketchum said engineering studies and site reviews are progressing favorably, and there are conversations with customers about offtake of the power it would produce if restarted.

NextEra Energy reported second-quarter 2025 earnings per share of $1.05 on revenue of $6.7 billion and net income of $2.03 billion, up from 96 cents, $6.07 billion and $1.62 billion in the same period of 2024.

Its stock price dropped 6.1% in trading July 23 to close at $72.82, near the middle of its 52-week range.

FERC Approves Constellation Purchase of Calpine with Conditions

FERC approved Constellation Energy’s $26.6 billion purchase of Calpine, creating an IPP with nearly 60 GW of generation around the country (EC25-43). 

In an order issued after the markets closed July 23, the commission found the deal, with divestment commitments and a settlement on bidding behavior with PJM’s Independent Market Monitor, is in the public interest. 

While Constellation is the surviving firm in the deal, Calpine’s main owners — ECP and AI Holdings — each still will control less than 10% of the new firm, which is below FERC’s standard for a controlling interest in a utility. 

The mitigation plan includes selling off 3,546 MW of generation, all of it located in PJM, that comes from the 1,134-MW natural gas combined cycle Bethlehem Energy Center, the 569-MW dual-fuel combined cycle York Energy Center Unit 1, the 1,136-MW dual-fuel combined cycle Hay Road Energy Center and the 707-MW simple cycle gas-fired Edge Moor Energy Center. 

The two firms have overlapping generation in ISO/RTOs around the country, but PJM is their biggest shared market, where, after consummation, Constellation will control 26.4 GW, or 14.9%, of its installed capacity. In some submarkets to the RTO, absent the mitigation plan, the merger would have given Constellation enough market power to fail standard screens, FERC said. 

Constellation and the IMM signed a deal July 3 where the firm agreed to some post-merger behavioral commitments to deal with the monitor’s concerns over its impact on market power. The deal is based on one that Constellation entered into with the IMM before the merger and extends behavioral commitments on its generation out to the 2035/36 capacity delivery year. 

The deal prevents the firm from selling any of 3,546 MW of generation to be divested to Dominion Energy and American Electric Power, or their subsidiaries. The IMM could disagree on other deals, including seeking restrictions at FERC, but Constellation would be able to oppose those arguments. 

The IMM settlement includes commitments for Constellation to bid into the capacity and energy markets at specific prices and requires notice for retirements. It also limits Constellation’s ability to enter into co-location deals with large loads such as data centers. 

“For a period of one year from the execution of this settlement agreement, Constellation agrees not to enter into any co-location arrangements under which the capacity serving the load delists, until and only if the commission issues an order, regulations or policy statement subsequent to the date of this agreement authorizing such a configuration,” it said. “For the avoidance of doubt, nothing in this agreement restricts the ability of Constellation or the [PJM] IMM to advocate for any particular co-location configuration or restriction on such configurations.” 

FERC found the mitigation plan appropriately addresses market power concerns brought up by Constellation’s acquisition of Calpine. 

“We accept Constellation Energy’s commitment to abide by the terms of the Constellation-PJM IMM agreements, and we condition our authorization of the proposed transaction on that commitment,” FERC said. 

The deal addresses market power concerns that the IMM and other intervenors made in the case, extending bidding rules Constellation already must follow in PJM to its newly acquired units and for an additional four years from the previous deal. Any changes to that deal before May 2036 would have to come before FERC to get approved, as the regulator is basing the deal’s approval on the commitments made there. 

Pennsylvania’s Consumer Advocate asked FERC to weigh the impact of the merger on the state’s competitive market and the default service auctions for customers who stay with the utility. FERC has said it would examine retail market impacts, but only if a state commission asks it to do so, and the PUC did not in this case. 

FERC also was unpersuaded by protesters’ arguments that it needed to examine the impact of ECP continuing to own less than 10% of the firm after the merger. Staying below that mark creates a rebuttable presumption that an entity lacks control. 

“ECP and AI Holdings will each hold less than 10% of the voting equity interests in Constellation and will not have any right to appoint a board member to the boards of Constellation or any of its subsidiaries,” FERC said. “Furthermore, applicants represent that there is no contract that gives ECP influence on the decision-making of Constellation or its public utility subsidiaries after consummation of the proposed transaction.” 

Battery Storage Revenue Average Trending Down in California

California’s fastest-growing energy resource — battery storage — is earning less net revenue per unit with each passing year, while capacity is expected to continue to boom in the Golden State.

Battery storage net revenue dropped from an average of $102/kW-year in 2022 to $78/kW-year in 2023, to $53/kW-year in 2024, indicating a “trend,” CAISO’s Department of Market Monitoring (DMM) said in a July 15 memo, which was included in reports provided to the July 22 general session of the Western Energy Markets Governing Body.

Lower peak energy prices are the primary cause of the revenue decline, and revenue from ancillary services also has continued to decrease significantly as the volume of battery capacity has increased, the DMM said.

Even so, an additional 14,000 MW of battery storage capacity is planned to be online by 2030, pushing CAISO’s total to about 28,000 MW by that year. Battery storage capacity has gone from 500 MW in 2020 to close to 14,000 MW as of June.

Nearby states also are going bonkers over batteries: Arizona plans to install more than 5,000 MW of additional battery storage capacity by 2028, while Nevada is looking to add about 2,500 MW by that year. In total, more than 19,000 MW is planned to be installed in Western Energy Imbalance Market (WEIM) states by 2028, DMM Executive Director Eric Hildebrandt said in the memo. Much of the battery capacity in other WEIM states is being installed to meet the renewable energy requirements of load-serving entities in California, Hildebrandt said.

The DMM recommended CAISO revise its bid cost recovery rules for batteries because the current rules “significantly decrease the incentive for batteries to bid in a manner that ensures their capacity is usually fully available during the most critical peak net load hours,” Hildebrandt said in the memo.

“In addition to increasing bid cost recovery payments and related gaming opportunities, this can result in batteries being discharged prior to the peak net load hours, when battery capacity is needed most,” Hildebrandt said.

In 2024, battery storage facilities in CAISO’s region received about $18 million in real-time bid cost recovery payments, representing 11% of total bid cost recovery payments and 4% of batteries’ total net market revenues.

Batteries tend to contract less than their maximum power capacity for resource adequacy purposes. This means batteries theoretically could provide more power than their RA value, Hildebrandt added.

During the five highest load days of 2024, battery storage resources provided significant RA capacity. However, RA storage capacity can drop in the later peak net load hours — when batteries are critical for system reliability — due to insufficient state-of-charge, Hildebrandt said.

In 2024, batteries supplied about 9% of CAISO’s energy during peak net load hours, while battery charging represented about 15% of CAISO’s load during mid-day hours, according to the memo. Battery charging helped reduce the need to curtail or export surplus solar energy at very low prices, the memo said.

CAISO will rely heavily on battery storage facilities to meet peak demand this summer, state energy officials said in May. A surplus of at least 5,500 MW is projected to be available to California during peak demand under normal conditions and 1,368 MW under extreme conditions, the officials said.

ISO-NE Analysis Details Benefits of Demand Flexibility

Increased demand flexibility could significantly reduce production costs, capital costs and transmission costs in New England by better aligning load with generation and reducing peak loads, ISO-NE said at the Planning Advisory Committee’s meeting July 23. 

Presenting additional results from its 2024 Economic Study, ISO-NE said demand flexibility could reduce production costs by 10 to 15% in 2050. The RTO found that capital cost savings would “increase linearly with increasing demand-side flexibility” by reducing reliance on “expensive resources that are only needed for short durations.” 

Demand flexibility would also provide emissions benefits by reducing load during the most carbon-intensive peak periods and would reduce the need for energy storage by limiting the imbalances between energy production and demand, ISO-NE found. 

As a caveat to its findings, the RTO noted that the demand flexibility modeling assumes “perfect foresight and total control over flexible load” and therefore may inflate savings projections. 

The study is intended to quantify the economic and environmental effects of state and federal energy policies and “evaluate competitive solutions to alleviate identified system efficiency needs.” (See “2024 Economic Study,” ISO-NE Details Evaluation Models for Transmission Solicitation; “Additional Economic Study Results,” ISO-NE Planning Advisory Committee Briefs: March 19, 2025; and ISO-NE Finds Advanced PV Panels Could Reduce Decarbonization Costs.) 

ISO-NE has previously forecast significant transmission savings associated with demand flexibility; it estimated in 2023 that the region could save up to $9 billion in transmission costs by reducing its forecast 57-GW peak load for 2050 to 51 GW. (See ISO-NE Prices Transmission Upgrades Needed by 2050: up to $26B.) 

Also at the PAC meeting, ISO-NE discussed a sensitivity analysis from the Economic Study reducing the capital cost assumptions for small modular nuclear reactors (SMRs). The RTO’s baseline assumptions for the study relied on conservative SMR cost projections from the National Renewable Energy Laboratory. 

“The lower cost assumptions for SMRs shifted [their] buildout from 2039 to the mid-2030s and reduced the buildout of other non-emitting resources,” said Kim Quach of ISO-NE. She noted that lower SMR costs also lowered reliance on peaker generation and largely eliminated the need for 100-hour battery storage. 

The RTO also discussed a model sensitivity reducing the emission-reduction requirements. It found that requiring only 75% decarbonization by 2050 would cut total costs by about 50% relative to the base case. The lower costs stemmed from decreased reliance on the most expensive clean resources needed to achieve deep decarbonization, including SMRs. 

While scaling back the long-term decarbonization of the power sector could significantly reduce electricity costs, it would make it extremely difficult for states to meet their climate targets and reach net-zero emissions by 2050. Rhode Island has set a goal of meeting 100% of its power demand with clean energy by 2030, while Massachusetts has estimated it will need to cut power sector emissions by 93% by 2050 relative to 1990 levels to reach its net-zero goal. 

The Intergovernmental Panel on Climate Change (IPCC) estimates that global emissions must decline significantly in the coming years and reach net zero by 2050 to limit warming to 1.5 degrees Celsius. Passing this warming threshold will intensify extreme weather events and have widespread negative impacts on human health, food and water supplies, and economic growth, according to the IPCC. 

Resource Outlook Study

ISO-NE anticipates minimal shortfall risks over the next decade, with the loss-of-load expectation falling below the one-in-10 reliability criteria for each year, ISO-NE’s Donald Poulin said in presenting the RTO’s 10-year resource outlook study. 

He noted that forecasted shortfall risks increase as the decade progresses because of growing load and the assumption of a stagnant resource mix. 

Asset-condition Projects

Chris Soderman of Eversource Energy presented a $24 million asset-condition project to replace 48 wood structures with steel structures on a 115-kV line in southern New Hampshire.  

The company has identified damage and deterioration on 25 structures and will replace additional “Category B” structures facing flooding, uplift issues or are in “close proximity” with more deteriorated structures, Soderman said. 

Under the transmission owners’ standardized PAC presentation guidelines, Category B refers to structures with moderate deterioration that may be replaced “in conjunction with other structure replacements.” 

Soderman also presented a $6 million project in New Hampshire to replace 15 wood structures on a separate 115-kV line. He said six of the structures have deteriorated to the point of needing replacement, while nine structures are categorized as Category B proximity structures. 

Connecticut Needs Study

ISO-NE also discussed a revision to its Connecticut 2034 Needs Assessment.  

Following an update to correct errors in the load distribution in Rhode Island, ISO-NE has reduced the extent of thermal overloads it forecasts for Connecticut in 2028 and 2034, along with the number of buses with low-voltage violations it forecasts for 2028. 

The revisions did not affect the number of high-voltage violations identified by the RTO, which are associated with minimum loads. 

The RTO plans to publish the draft assessment “in the near future” and aims to release the final version in August. It intends to begin work on the Connecticut 2034 Solutions Study in the third quarter of this year, focusing on short-term needs. 

GE Vernova’s Gas Power Equipment Surge Continues

GE Vernova’s gas power and electrification businesses continue to surge amid growing power demand.

The company on July 23 reported second-quarter financials that exceeded projections and offered an optimistic message that sent its stock price soaring to all-time highs.

CEO Scott Strazik said GE Vernova’s backlog for gas-fired turbines grew from 50 GW of orders and manufacturing slot reservations to 55 GW in the second quarter, and he expects to end the year at 60 GW. The longer-term expectation is 80 to 100 GW of backlog.

The company’s large heavy-duty gas turbines are in high demand, but there also is growing demand for its small aeroderivative gas turbine packages that leave the factory 95% preassembled.

Just a day earlier, GE announced it would sell 29 of these smaller units rated at 34 MW each — nearly 1 GW in total — to Crusoe for its AI data centers.

This technology — essentially a modified jet engine with emissions controls — is quick to deploy, quick to start up and can provide a bridge solution when the interconnection queue is moving more slowly than the customer wants to. Eventually, the aeroderivative turbines can become backup power sources for a facility or connect to the grid, Strazik said.

GE Vernova also has its name on a massive installed generation fleet built by General Electric and is seeing strong growth in its service business, Strazik said.

“Our services backlog also grew approximately $1 billion in the second quarter,” he said. The company has been incrementally increasing its pricing on new equipment orders and will be doing so with its service business.

During an earnings call July 23, an analyst asked what effect sharp changes in federal energy policy are having on GE Vernova.

The reconciliation bill was finalized only a few weeks ago, Strazik said, so it is early to draw conclusions. However, GE Vernova has seen accelerated interest — but not yet orders — for grid equipment supporting wind and solar generation, he said. That is near- to mid-term interest, he said, which would match with the impending end of federal tax credits for wind and solar energy development.

“There also is very clear market sentiment that into the next decade, there’s going to be a need for more gas,” Strazik said. “I would say our pipeline of activity for gas demand is only growing, but it’s growing at even more healthy levels for ’29 deliveries, ’30, ’31 — periods of time where, maybe prior to the bill being signed, some of our traditional customers may have been intending more wind or solar.”

GE Vernova’s second-quarter results surpassed projections, pushing first-half 2025 revenue, earnings, free cash flow and backlog higher than year-ago levels. The company has increased its projections for the second half of 2025.

The price of GEV stock soared throughout the trading day, closing 14.6% higher than July 22 and 349.3% higher than on the close of its first day of trading in April 2024.

Also with its second-quarter financial results, GE said:

    • Steam power service orders jumped on efforts to upgrade existing nuclear reactors and extend their operation.
    • Even larger growth was seen in hydropower, again due to upgrades.
    • Progress continues on development of the 300-MW small modular reactor that is the first SMR being built in North America; more customer announcements are expected in the second half.
    • Demand for synchronous condensers, a longstanding but minor line for the company, is expected to grow with the need for grid-stabilizing technology, Strazik said. “We see this as a credible $5 billion market opportunity a year.”
    • Onshore orders in North America drove an increase in revenue for the wind business, offset by continued losses offshore; it may approach the break-even point in the second half.
    • The electrification business saw a $2 billion increase in backlog, driven by switchgear and transformers.

DOE Pulls $4.9B in Funding for Grain Belt Express

The Department of Energy says it has terminated its $4.9 billion conditional loan commitment for the long-delayed Grain Belt Express project, saying it is “not critical” for the federal government to support the project.

“After a thorough review of the project’s financials, DOE found that the conditions necessary to issue the guarantee are unlikely to be met,” the DOE said in a July 23 press release.

DOE said the Loan Programs Office’s loan guarantee, issued by the Biden administration in November 2024, was one of many conditional commitments “rushed out the door” shortly after the 2024 election.

A project spokesperson said the developers are disappointed with the withdrawn LPO loan guarantee, noting that the Grain Belt Express “will be America’s largest power pipeline.”

“A privately financed Grain Belt Express transmission superhighway will advance President Trump’s agenda of American energy and technology dominance while delivering billions of dollars in energy cost savings, strengthening grid reliability and resiliency, and creating thousands of American jobs,” the spokesperson said in an email to RTO Insider.

Rob Gramlich, Grid Strategies’ president, said the decision was “confusing,” given the administration’s focus on the need for energy to power artificial intelligence data centers.

“We really need interregional transmission and [DOE] Secretary [Chris] Wright and now the White House, through their AI plan, say transmission is important,” he told RTO Insider.

The DOE said it is conducting a review of every applicant and borrower, including the nearly $100 billion in closed loans and conditional commitments the LPO made between Election Day 2024 and Inauguration Day 2025.

DOE’s action is the latest hurdle facing the Grain Belt Express, an 800-mile HVDC project that has been under development since 2010. The project’s developer, Invenergy, says the $11 billion merchant transmission line would be capable of moving 5 GW of mostly clean energy from Kansas across Missouri and Indiana and into Illinois.

The news was celebrated by U.S. Sen. Josh Hawley (R-Mo.), who has called the project a “boondoggle” and twice sent letters to the DOE urging the agency to cancel the loan guarantee. Hawley took credit for the cancellation, charging that the project “has taken the land of numerous Missouri farmers across eight counties while padding [Invenergy’s] corporate profits.” (See Grain Belt Funding Appears on Shaky Ground with DOE; Invenergy Firm on Value.)

The project has been approved by regulators in all four states involved. The Missouri Public Service Commission found the project would save the state’s customers as much as $18 billion, Invenergy has said. The company noted municipal utilities in 39 communities have contracts with it for power delivery and contractually guaranteed cost savings.

However, the project has faced opposition from Missouri landowners, who are opposed to a for-profit, private entity using eminent domain. Missouri Attorney General Andrew Bailey has criticized Grain Belt Express for filing nearly 50 eminent domain lawsuits against Missouri landowners. He opened a consumer protection investigation into the project in June. (See Missouri AG Opens Inquiry into Grain Belt Express.)

Bailey issued a statement saying his office has “won a battle in the war for Missouri landowners” in what he termed an “unconstitutional land grab.”

“If Invenergy still intends to force this project on unwilling landowners, we will continue to fight every step of the way,” he threatened.

The project’s developers filed a lawsuit against Bailey July 16, arguing that he does not have the authority to investigate Grain Belt Express or to interfere with the Missouri PSC’s final order.

Invenergy says the $11 billion project would provide $52 billion in energy cost savings over 15 years, create 5,500 jobs and power up to 50 data centers.

A 2022 economic analysis conducted for Invenergy found that the project would result in $20 billion in total investment and create more than 20,000 temporary jobs and more than 400 permanent jobs in Illinois, Kansas and Missouri.

Invenergy says the Grain Belt Express would move a “diverse mix of energy” from Kansas to Indiana. The project would save money and strengthen reliability for 29 states and D.C., and more than 40% of Americans, it said.

The project would create links between the SPP, MISO, Associated Electric Cooperative Inc. and PJM grids.

Grain Belt Express has been under development since 2010, when the now-defunct Clean Line Energy first proposed the transmission line. After years of regulatory, legal and political hurdles, Clean Line sold the project to Invenergy. (See Invenergy Renewing Push for Grain Belt Express.)

Grain Belt Express announced nearly $1.7 billion in combined contractor awards to Quanta Services and Kiewit Energy Group.

FERC Approves MISO Interconnection Queue Fast Lane

FERC on July 21 approved a controversial MISO proposal to create a fast lane for certain reliability-related projects in the RTO’s interconnection queue — just two months after rebuffing an earlier version of the plan (ER25-2454).

The commission in May rejected the first iteration of the Expedited Resource Addition Study (ERAS) proposal, which was designed to speed up interconnection of resources that state regulators have identified as necessary to ensure resource adequacy in areas under their oversight.

In its May decision, the commission found the original ERAS plan lacked clarity around standards for identifying true RA projects and that — absent a cap on potential applicants — the expedited process was at risk of becoming bogged down with too many proposed projects. (See FERC Rejects MISO’s Interconnection Queue Fast Lane.)

Responding to those concerns, MISO quickly developed a revised proposal that caps the ERAS fast lane at 68 project requests and includes a provision requiring the RTO’s relevant electric retail regulatory authorities (RERRAs) to verify in writing that a project will either address an RA risk or help load-serving entities meet previously unexpected load growth.

Of the 68 slots, MISO proposed that a maximum of 10 would be carved out to accommodate requests from independent power producers that have agreements with entities other than LSEs, while eight will be dedicated to requests for resources intended to serve retail-choice load.

The RTO also proposed to cap the number of expedited studies to just 10 per quarter and limit transmission service requests to 150% of the need identified by a RERRA. It also made clear the ERAS process would be a temporary fixture, concluding at the earlier of either August 2027 or when the queue is cleared.

While MISO’s rapid turnaround on the revision earned support from the RTO’s vertically integrated utilities, it provoked protests from independent power producers and clean energy groups, who argued the newer plan still retained “many of the shortcomings” of the earlier version while introducing additional legal concerns. They also argued it still offered “preferential access to thermal resources at the expense of renewable resources.” (See MISO’s Queue Fast Lane, Take 2, Nets Déjà vu Arguments.)

Michigan’s Public Service Commission also opposed the plan, arguing it lacked “sufficient enforcement of shovel readiness and project completion” and that a provision to cap the megawatt value of expedited projects at 150% of an identified RA need might exclude meaningful participation by developers of renewable energy projects, which have lower capacity factors than thermal projects.

In its comments to FERC, Invenergy argued the new proposal still vested RERRAs with “nearly unbounded discretion to select projects, without any objective criteria to judge whether such projects are capable of satisfying MISO’s resource adequacy needs.”

But the revised plan had strong backing among MISO’s utilities, among them Alliant Energy, Ameren, Big Rivers Electric, Consumers Energy, DTE Energy, Northern Indiana Public Service Co. and Ottertail Power.

‘One-time Design’ Weighs Heavily

FERC’s July 21 order found the eligibility requirements set out in the revised proposal were adequate to “deter speculative interconnection requests from entering the ERAS process and minimize disruption” to resources already sitting in the definitive planning phase of MISO’s existing interconnection process.

“We find that MISO’s revised ERAS proposal sufficiently addresses these concerns identified in the May 2025 order by capping the number and size of ERAS projects, strengthening the RERRA verification requirement, [and] requiring ERAS interconnection requests to be located in the same local resource zone as the resource adequacy or reliability need that it will address,” the commission wrote.

“Additionally, we note that the limited, one-time design of the process weighed significantly on our decision here,” it added.

The commission also found that MISO had “strengthened” the “notification” requirement in the initial ERAS plan “to better ensure that RERRAs affirmatively verify interconnection requests will address specific resource adequacy needs that are not otherwise being addressed.”

The commission said it was “reasonable and appropriate” for MISO to allow RERRAs to select the ERAS projects and “implement their own processes for making such determinations, as this approach strikes a reasonable balance between state authority over resource procurement and commission authority over generation interconnecting to the interstate transmission system. Accordingly, we find that it is not necessary for MISO to establish scoring criteria or a ranking process for proposed ERAS projects, as protesters suggest.”

The commission rejected the argument by IPPs that the proposal intrudes on the commission’s exclusive Federal Power Act jurisdiction over the transmission service terms and conditions set out in MISO’s tariff.

To support their argument, the IPPs cited the U.S. Supreme Court’s Hughes v. Talen Energy Marketing decision, which held that the Maryland Public Service Commission’s authority over generating facilities did not allow it to “exercise control over the terms and conditions of interconnection service.”

“We find that the revised ERAS proposal is permissible under Talen because RERRA participation in the ERAS process would be wholly pursuant to a commission-jurisdictional process (i.e., the generator interconnection process), proposed by MISO and approved by the commission — not by state authorities — and under which a [generator interconnection procedure] is on file with the commission and any future revisions would be subject to commission approval,” FERC wrote.

The commission also rejected the contention that the proposal violates the “filed rate” doctrine because it allows states — through their RERRAs — to set the criteria for determining a resource’s participation in ERAS without subjecting that criteria to FERC approval.

“NextEra and MISO IPPs argue that the revised ERAS proposal violates the filed-rate doctrine because it allows RERRAs to establish criteria that would not be on file with the commission and that would determine whether or not an interconnection request is eligible for ERAS. We disagree. We find that the revised ERAS proposal does not present a filed-rate doctrine concern because it provides adequate notice of the ERAS eligibility requirements, including the RERRA verification requirement,” the commission wrote.

MISO intends to kick off the first ERAS process on Sept. 2.
