Former FERC Commissioners Ask Supreme Court to Preserve Agency Independence

Eleven former FERC commissioners filed a brief with the Supreme Court arguing it should uphold Humphrey’s Executor or carve out an exception for ratemaking agencies.

The court is poised to hear oral arguments in Trump v. Slaughter on Dec. 8, in which former Federal Trade Commissioner Rebecca Kelly Slaughter is arguing President Donald Trump overstepped his authority in firing her in March.

The case comes 90 years after the Supreme Court found that Congress could limit the president’s authority to fire members of regulatory agencies in another case involving an FTC commissioner, which has helped guarantee agency independence since then. In an order overturning an injunction in a related case earlier this year, a majority on the court seemed poised to overturn the precedent but noted it would benefit from briefing on the issues. (See Will the Supreme Court End FERC’s Independence?)

“Overturning Humphrey’s Executor would bulldoze the structural supports that Congress built into ratemaking commissions to protect its price-setting power from abuse,” according to the brief, which was prepared by the Harvard Electricity Law Initiative’s Ari Peskoe.

The amici curiae in the brief are a bipartisan group of former FERC commissioners who were nominated by all but one of the presidents from Ronald Reagan through Trump’s first term: Elizabeth Anne Moler, Donald Santa, Linda Breathitt, Pat Wood III, Nora Mead Brownell, Joseph T. Kelliher, Jon Wellinghoff, John Norris, Cheryl LaFleur, Neil Chatterjee and Richard Glick.

Congress has given ratemaking authority to multimember bipartisan commissions dating back to 1887 and limited the president’s power to fire members only for “inefficiency, neglect of duty or malfeasance in office.”

“By shielding agency action from political control, for-cause removal protections allow ratemaking commissions to sustain stable policies for the long-term benefit of regulated companies and American consumers,” the brief says.

If the court decides to overturn or clarify Humphrey’s Executor, the brief urged it to consider the “special historical status” it has indicated the Federal Reserve has in the Seila Law decision in 2020, in which the court found the president had unchecked authority to fire the director of the Consumer Financial Protection Bureau.

Ratemaking agencies wield “legislative power” to set prices for investor-owned companies, the brief argues, and among all multimember agencies, only the Federal Reserve Board plays such a direct role in the economy, doing so with similar “legislative discretion.”

“Overturning Humphrey’s Executor without acknowledging ratemaking commissions’ special status would greenlight one-party ratemaking bodies and allow presidents to eliminate staggered terms by firing holdover commissioners nominated by a previous president,” the brief says. “Permitting the president to seize control over ratemaking could adversely affect how regulated companies perceive FERC and therefore increase the risk of financing pipelines and power lines. Ultimately, American consumers would pay higher energy prices.”

Eliminating for-cause removal protections risks turning FERC into a partisan political body whose priorities flip every election cycle, and the resulting volatility would conflict with its historic focus on the long-term interests of consumers and the industries it regulates, the brief argues. Congress affords ratemaking commissions with wide discretion as they balance competing interests to find just and reasonable rates, and their bipartisan composition is an antidote against abuse of that discretion, it says.

“For-cause removal protections, staggered terms and partisan limits temper agency discretion by ensuring that decisions are informed by diverse and balanced perspectives,” the brief says.

The Massachusetts legislature was the first body to set up a ratemaking commission in 1869 to regulate what railroads charged in the state, and it was quickly followed by other states. The court upheld their creation in an 1877 decision.

A decade later, after the court found those state ratemaking commissions could not regulate interstate commerce, Congress set up the Interstate Commerce Commission to check the power that railroads exerted over the economy. The ICC had to have five commissioners with no more than three from one party; commissioners served staggered terms, could not hold other jobs, were forbidden from investing in regulated companies and had for-cause removal protections.

The ICC’s structure remained durable and was adopted for other agencies over the years, including when Congress passed the Department of Energy Organization Act in 1977. Congress specifically rejected President Jimmy Carter’s proposal to give DOE the old Federal Power Commission’s ratemaking authority, with members arguing the power should go to a “collegial” body and not the department, where only the president’s policies would guide its decisions.

“The age of the kings expired with the French Revolution,” Rep. John Dingell (D-Mich.) said at the time, according to the Congressional Record. “I plead with this body, do not set up a new king here in Washington.”

Dingell’s “rhetorical flourish focused his colleagues on threats to liberty,” which are a core concern in separation of powers cases, the brief says.

“By seizing ratemaking authority, ‘one of the great functions conferred on Congress by the federal Constitution,’ the president would secure vast direct control over the economy,” the brief says. “Price-setting power would allow the president to increase profits of favored companies at the expense of consumers, who would face higher prices for goods and services. The president could also punish companies that oppose his policies or even raise energy prices in states that support his political rivals.”

Congress wanted ratemaking power to be exercised in the “coldest neutrality” rather than unilaterally by the executive branch, the brief says.

“Elevating executive control over bipartisan deliberation, as petitioners urge, misunderstands Congress’ ratemaking statutes and threatens to destabilize an economic model that has stood the test of time,” the brief says.

The Supreme Court has repeatedly called the commission’s ratemaking authority “legislative,” so the commissioners urged the court, even if it overturns Humphrey’s Executor, not to foreclose the possibility that ratemaking commissions remain immune from direct executive control. Separation of powers ought to allow Congress to create deliberative ratemaking bodies.

“FERC plays a direct role in our economy that, among the multimember agencies, is matched only by the Federal Reserve Board,” the brief says. “Prices set by FERC are essential inputs across the economy that directly affect the cost of living and doing business. Maintaining for-cause removal protections for ratemaking commissions exercising legislative power would appropriately defer to Congress’ powers over interstate commerce.”

The brief also examines FERC’s economic impact. It regulates 200,000 miles of interstate natural gas pipelines, 120,000 miles of high-voltage transmission and 85,000 miles of interstate crude pipelines, which transport more than $1 trillion worth of commodities per year.

That work remains important as artificial intelligence and reshored manufacturing grow the demand for electricity, and the oil and gas industry works to increase shipments of LNG abroad.

“FERC is more important than ever to American energy producers and consumers,” the brief says. “Any change to FERC’s structure should follow careful deliberations in Congress that weigh the potential benefits of reform against the possible harms caused by transforming FERC into a politically partisan body.”

The commission’s authority over energy markets gives it a direct and central role in the economy, like the Federal Reserve. The brief quotes former Federal Reserve Chair Alan Greenspan as saying, “Energy markets will remain central in determining the long-run health of our nation’s economy.”

“Like interest rates set by the Federal Reserve Board, energy prices impact costs across the economy and have material effects on total investment and consumption,” the brief says. “Congress charged FERC and the Federal Reserve with promoting stable prices, which provide households and businesses with confidence to invest.”

NERC Manager Shares Outlook on Long-term Assessments

NERC is working to enhance its Long-Term Reliability Assessments and make them more useful for industry stakeholders amid a rapidly changing energy environment, Mark Olson, the ERO’s manager of reliability assessments, said in an online workshop Nov. 12.

Speaking to the 2025 Planning and Modeling Virtual Seminar, hosted by NERC, the North American Transmission Forum and the Electric Power Research Institute, Olson said NERC’s LTRAs “are critical to talking to stakeholders about what the concerns are … and we rely on industry information to make these reports credible.” But he also said the ERO has noticed “limitations” in its current approach to the assessment that make the resulting document less informative in this environment.

“For a long time, we were managing the risks that were associated with a changing resource mix and new resource types,” Olson said. “In recent years, as you’re all well aware, with data centers and electrification and the speed [at] which load can request to come onto the system, the resource adequacy challenge has changed.”

NERC publishes the LTRA each December based on information collected from the regional entities, with the goal of “identifying trends, emerging issues and potential risks during the upcoming” 10 years. Olson observed that the LTRA originally was “designed around capacity-based methods,” with heavy emphasis on planning reserve margins.

The ERO introduced probabilistic assessments to the development process, which “have become more and more energy-based [to] take into account the energy limitations of resources,” Olson said. However, methods of performing probabilistic assessments can vary between regions, which means the resulting LTRA can be inconsistent and confusing to stakeholders.

To bring more consistency to the LTRA, Olson said the REs for the Eastern, Western and Texas Interconnections are collaborating this year on interconnection-wide energy assessments. The REs used off-the-shelf software to create a common platform and standardize the assumptions that would go into their reports.

Olson emphasized that this is a pilot program that is “about building the capability to do the work” rather than providing a “reliability takeaway” for this year, and the results will not be published in the 2025 LTRA. Nevertheless, he praised the REs’ work for setting the foundation for future interconnection-wide assessments.

“This is really something we’re pretty proud of,” Olson said. “In the past, some [REs] would perform an assessment over their entire … footprint. But for this work, each [RE] was coordinating with their neighbor regions across the interconnection and coming with the same assumptions … and resolving challenges as they went. All of these regions working off of a common tool, and a common model of the interconnection, is a pretty big step.”

Olson said NERC also has benefited from the Interregional Transfer Capability Study, which the ERO filed with FERC in 2024 as ordered by Congress in the Fiscal Responsibility Act of 2023. Not only were the REs’ interconnection-wide assessments based in part on the models used for the ITCS, but the 2025 LTRA could make use of the data collected for the study.

“This is really about adding to our LTRA a level of information that helps us understand how non-firm transfers can help resolve risks. It also brings in transmission adequacy or transfer capability into our assessments … on an interconnection-wide scale, and we haven’t had that in the past,” Olson said. “It will really set the stage for scenarios where [if] you want to look at, say, fuel outages, fuel events or wide-area cold weather [or] heat domes, those kind of things, we’ll have an interconnection-wide energy analysis model that would allow us to study that.”

IEA World Energy Outlook 2025 Quantifies Rising Global Power Demand

The International Energy Agency released its World Energy Outlook 2025, which found new emerging economies are poised to drive the near-term future of energy.

China accounted for half of oil and gas demand growth and 60% of electricity demand growth for the past decade, but in the future the markets will be driven by what happens in India, Southeast Asia and countries in the Middle East, Africa and Latin America. No country, or even group of them, is expected to come close to replicating the scale of China’s energy-intensive rise.

The world continues to face security risks to oil and gas supplies, but IEA said China’s dominance of rare earth minerals vital to power grids, batteries and electric vehicles now accompany those much older risks. China is the dominant refiner for 19 out of 20 energy-related strategic minerals, with average market share across those of around 70%.

“When we look at the history of the energy world in recent decades, there is no other time when energy security tensions have applied to so many fuels and technologies at once — a situation that calls for the same spirit and focus that governments showed when they created the IEA after the 1973 oil shock,” IEA Executive Director Fatih Birol said in a statement. “With energy security front and center for many governments, their responses need to consider the synergies and tradeoffs that can arise with other policy goals — on affordability, access, competitiveness and climate change.”

Electricity is at the heart of modern economies, and its demand grows faster than overall energy demand in all scenarios that IEA ran for its report. In 2024, the group said the world was moving into the “Age of Electricity”; that already has arrived, it said in the latest report.

“In a break from the trend of the past decade, the increase in electricity consumption is no longer limited to emerging and developing economies,” Birol said. “Breakneck demand growth from data centers and AI is helping drive up electricity use in advanced economies too. Global investment in data centers is expected to reach $580 billion in 2025. Those who say that ‘data is the new oil’ will note that this surpasses the $540 billion being spent on global oil supply — a striking example of the changing nature of modern economies.”

With the growing importance of electricity and pressures from growing demand adding to higher prices, electricity bills are rising to the top of the political agendas in many countries, the report said.

“This shift underscores a growing tension: While electrification offers long-term efficiency gains and emissions reductions, it also increases the sensitivity of movements in electricity prices, which are shaped by a complex mix of fuel costs, infrastructure investment, market design and policy choices,” the report said.

Electricity is becoming a larger share of household energy spending around the world because of electrification. The report expects average household demand to grow by 25% by 2035 and 60% by 2050, with significant variations by region.

Advanced economies have a decadelong trend of demand stagnation, but households there should see it grow by 15% by 2035 and 35% by 2050.

“While increases in energy efficiency moderate consumption for appliances, the electrification of transport is a major driver of expanding electricity use in regions with supportive policy frameworks and increasing EV sales shares,” the paper said. “This shift underscores the need for grid readiness and demand flexibility solutions like smart charging to manage peak demand and to improve affordability.”

Developing countries will see even higher household demand growth – 30% by 2035 and 90% by 2050 — because of air conditioning that comes from rising incomes and higher average temperatures.

“Rapid growth in electricity demand brings with it a need for substantial investment across the power sector,” the report said. “Grid infrastructure, in particular, is seeing a marked increase in capital spending to connect new loads, integrate new sources of electricity and enhance resilience. While rising investment does not necessarily translate into higher average system costs — especially if demand rises in parallel — the financing conditions and timing of the investment are critical.”

Some things are working to lower prices, with IEA saying natural gas prices should drop in many markets as more LNG becomes available and the growth in renewable power helps bring down wholesale electricity prices.

“As electricity demand rises, the fixed costs of new infrastructure can be spread across a larger volume of consumption, potentially reducing the cost per megawatt-hour,” the report said. “In some cases, this dynamic may even lead to lower electricity prices in real terms despite rising investment levels, highlighting the importance of well designed policies and market frameworks that enable efficient investment recovery while protecting consumers.”

How ERCOT’s RTC+B is a Game-changer for Market Operations

Portia Gilman

ERCOT is preparing to launch its Real-Time Co-Optimization + Batteries (RTC+B) initiative, perhaps the most sweeping market redesign in its history.

This transformation, scheduled to launch Dec. 5, will touch virtually every aspect of the market, from energy to ancillary services, introducing a more dynamic, efficient and integrated approach to market operations.

For battery operators in particular, RTC+B is a game changer. The redesign recognizes batteries not as separate charging and discharging assets but as unified energy storage resources (ESRs), allowing operators to more easily participate simultaneously in energy and ancillary services markets. This shift will enable batteries to capture more value, optimize dispatch and contribute to overall market efficiency in ways that were impossible under ERCOT’s legacy design.

ERCOT’s RTC initiative has been years in the making. It initially was focused solely on creating a real-time, co-optimized market that simultaneously would clear energy and ancillary services, accounting for each resource’s capabilities and system conditions to determine the most efficient dispatch. Following ISO-NE’s introduction of a co-optimized market in March 2025, ERCOT will be the last ISO to make this shift.

ERCOT paused its RTC initiative in the wake of Winter Storm Uri. The project was restarted in 2023, adding the battery (+B) component to reflect the rapid growth of battery energy storage capacity in ERCOT.

Texas is one of the fastest-growing battery storage markets in the country, second only to California in terms of installed capacity. In fact, ERCOT nearly doubled its battery capacity between 2023 and 2025 and is now approaching 10 GW.

Even more capacity is in the pipeline. Yes Energy is tracking more than 1,100 battery projects, totaling 180.5 GW, under construction or in development across the region.

Market Design Overhaul

RTC+B fundamentally reshapes how ERCOT manages energy and ancillary services, creating a market that’s more dynamic, efficient and aligned with modern resources like batteries.

At the heart of the redesign is the replacement of legacy constructs such as the operating reserve demand curve (ORDC) with ancillary services demand curves (ASDCs). These curves provide product-specific pricing for reserves — including regulation up ECRS and spinning reserves — enabling batteries and other flexible resources to see relative value signals and prioritize offers accordingly.

The RTM – Before (Pre-RTC) | Yes Energy

Under RTC+B, energy and ancillary services are co-optimized in real time, meaning ERCOT simultaneously clears energy and reserves through the SCED rather than relying on a separate ORDC process to clear reserves. Co-optimization already exists in the day-ahead in ERCOT and will continue after RTC+B.

This real-time co-optimization ensures that resources are dispatched efficiently across both markets, with the goals of improving overall market efficiency, reducing real-time energy costs and narrowing day-ahead to real-time price spreads over time.

ERCOT also will introduce virtual offers for ancillary services in the day-ahead market, which will increase liquidity by allowing more resources, including batteries, to participate flexibly.

To prepare for these changes, ERCOT conducted market trials in three stages: open-loop testing, closed-loop testing and final go-live validation. These trials allow participants and market operators to observe clearing prices, test new reports and ensure that the transition to RTC+B will be as seamless as possible.

Batteries Take Center Stage

Under ERCOT’s legacy framework, batteries were split between charging and discharging functions, treated as two separate resources with separate datasets in ERCOT’s systems. This “combo model” created extra complexity for resource owners, requiring manual processes to achieve consistency across operating plans, telemetry and bid curves. RTC+B eliminates this dual structure, replacing it with a single energy storage resource (ESR) designation that unifies a battery’s operations into one resource type.

Batteries will submit a combined energy bid-offer curve (EBOC), which integrates both charging and discharging into a single market signal. Negative EBOC values represent charging, allowing batteries to signal both their willingness to consume and supply energy. A low sustained limit (LSL) will replace the maximum power consumption (MPC) parameter, enabling operators to define realistic operational constraints within the unified framework.

This structure allows batteries to participate dynamically across both energy and ancillary services markets, supporting real-time co-optimization. Battery operators also can adjust day-ahead awards in real-time based on updated system conditions, pivot quickly between market products and respond to five-minute reserve updates.

RTC+B will transform how participants interact with ERCOT through data and operational reporting. Under the new framework, resources, including batteries, will integrate EBOCs, LSLs and regulation signals into ERCOT’s new market-clearing and settlement processes.

These capabilities not only give operators unprecedented flexibility and revenue potential, but also should improve market liquidity, enhance competition and help moderate price spikes for both energy and ancillary services.

The RTM – After (Post-RTC) | Yes Energy

In other words, with RTC+B, batteries no longer are just flexible resources. They become central drivers of ERCOT’s next-generation market efficiency.

Looking Ahead

With RTC+B, batteries move from being supporting players to central drivers of ERCOT’s next-generation market. By unifying charging and discharging into a single energy storage resource, introducing realistic operational bids and offers through the new EBOC, and integrating along with real-time co-optimization across energy and ancillary services markets, the redesign unlocks new operational flexibility and revenue potential.

As the Dec. 5 go-live approaches, battery operators who understand and use these changes will be well positioned to capture value, enhance market efficiency and shape the future of the Texas electricity system.

NEPOOL Committees Support ISO-NE Prompt Capacity Auctions

WESTBOROUGH, Mass. — NEPOOL technical committees voted in favor of ISO-NE’s proposal to adopt a prompt capacity auction and update the RTO’s resource retirement process, indicating broad stakeholder support for the first phase of ISO-NE’s capacity market overhaul.

In a joint meeting Nov. 12, the NEPOOL Markets Committee voted 97.9% in favor of the proposal and approved one of three amendments proposed by stakeholders. The NEPOOL Transmission Committee voted to support the associated transmission-related changes.

The proposal encompasses the first phase of work in ISO-NE’s Capacity Auction Reform (CAR) project. The RTO began stakeholder discussions in September on the second phase of the project, which centers around accreditation changes and shifting to a seasonal capacity market. (See ISO-NE Kicks off Talks on Accreditation, Seasonal Capacity Changes.)

While ISO-NE plans to file the two phases separately, both are intended to take effect for the 2028/29 capacity commitment period (CCP).

Under the proposed changes, ISO-NE would hold capacity auctions about a month prior to the start of each CCP, compared to the more than three years that historically have separated Forward Capacity Auctions and CCPs.

The proposal also would decouple resource deactivation from the auction process. ISO-NE has said processing resource deactivations in the immediate leadup to prompt auctions would not give it enough time to address any issues triggered by retirements. In the Forward Capacity Market, resources submit delist bids more than four years before the relevant CCP.

ISO-NE proposes to require resources to submit deactivation notifications one year before the start of the relevant CCP. It has said the one-year deadline balances the tradeoffs between a longer timeline, which would give ISO-NE and market participants enough time to respond to retirements, and a shorter timeline, which would enable resources considering retirement to make a better informed decision.

While the changes received widespread support from NEPOOL members, several stakeholders outlined lingering concerns about the risk that ISO-NE will not be able to obtain FERC approval of the second phase of CAR changes in time for the 2028/29 CCP, leaving the Phase 1 changes to stand alone for the first prompt auction.

Stakeholders also expressed concern that the shorter retirement notification period will increase the risk of out-of-market resource retentions. They emphasized the need to encourage bilateral transactions to protect against price volatility.

The MC also voted 83.3% to adopt an amendment by the New England Power Generators Association (NEPGA) to maintain ISO-NE’s current rules allowing capacity supply offers to reflect resources’ physical limitations in high ambient temperatures.

ISO-NE had proposed to eliminate its option for resources to submit ambient air delist bids associated with capacity it would not be able to provide when ambient temperatures exceed 90 degrees Fahrenheit. These delist bids are not subject to cost review by the Internal Market Monitor.

NEPGA made the case that, without the amendment, market participants would “unnecessarily be required to submit a cost workbook for megawatts it is physically unable to produce at those high ambient temperatures.” It proposed “technical conforming language” extending the existing exemption to the new design. ISO-NE indicated it would adopt the changes into its proposal.

The MC rejected a pair of proposals related to the competitive offer price threshold (COPT), which sets the price above which offers are subject to Monitor review.

Under ISO-NE’s proposal, the RTO would continue to calculate the threshold based on the previous capacity auction clearing price and forecasting for the upcoming auction.

Several stakeholders have expressed concern that relying on four-year-old prices to set the threshold in the transition to a prompt auction could create issues related to stale data, pointing to higher prices in recent annual reconfiguration auctions and a recent increase in Pay-for-Performance penalties.

Calpine and LS Power each offered amendments to the threshold methodology. Calpine proposed basing the threshold on a calculation of the opportunity cost associated with scarcity revenues, while LS Power proposed a one-year fixed price for the 2028/29 CCP based on the outcomes of recent reconfiguration auctions.

Both proposals fell short of the 60% voting threshold for MC support. Calpine’s proposal received 53.8% support, and LS Power’s received 56.7%.

ISO-NE acknowledged the concerns about stale data and said it plans to take a more in-depth look at the threshold in the second phase of the CAR project.

If the second phase of CAR is not approved prior to the 2028/29 CCP, “the ISO anticipates that it would make further updates to the [Phase 1] design, which would include an assessment of the COPT given the latest information available,” the RTO noted in a memo published prior to the meeting.

Top Mass. House Members Seeking Major Rollback of Climate Laws

Top Massachusetts House members are pushing an expansive energy bill that would scale back several major climate initiatives and programs and give the state immunity from legal challenges that result from missing its 2030 climate targets.

While the bill appears to have almost no chance of passing in the Senate, the legislation marks a significant change in the House’s approach to climate and energy policy. The bill has drawn immediate outcry from climate and consumer advocates. And it sets the stage for a high-profile clash between environmental advocates and industry groups that historically have opposed climate policy.

“This bill is a major attack on the climate policy that we’ve had since 2008,” Larry Chretien, executive director of the Green Energy Consumers Alliance, told RTO Insider.

The legislation, sponsored by Rep. Mark Cusack (D), responds to a wide-sweeping energy bill introduced by Gov. Maura Healey (D) in May. (See Mass. Gov. Healey Introduces Energy Affordability Bill and Stakeholders Mixed on Massachusetts Energy Affordability Bill.) Cusack is the top House member on the legislature’s powerful Joint Committee on Telecommunications, Utilities and Energy.

While Cusack’s and Healey’s bills both claim to take aim at energy affordability challenges in the state, their approaches vary significantly. While Healey’s bill takes a more technocratic approach to cutting energy costs and largely avoids cuts to climate and clean energy initiatives, the House bill would seek to cut costs by taking aim at a myriad of decarbonization programs and requirements.

“This is a bill that saves significant money, real hard dollars, that people will see the impact of,” Cusack said in a recent interview with the CommonWealth Beacon. He added that the Trump administration has significantly set back the state’s ability to meet its near-term climate targets and that changes to the climate targets are necessary to protect the state from lawsuits.

The bill includes several proposals favored by industry groups, including the changes to the state’s decarbonization targets and regulatory changes that could make it easier to finance new pipeline projects. (See Gas Industry Sees Political Opportunity in New England.)

“It’s a pro-utility bill, it’s a pro-natural gas bill,” Chretien said, adding that he was surprised by the extent of the proposed policy rollbacks. “I don’t think it’s a foregone conclusion that this passes the House.”

Key Components

The bill’s proposals include significant changes to the Mass Save energy efficiency program, which has become an important vehicle for incentivizing heating electrification in recent years.

It would reduce the budget for the 2025-27 Mass Save plan from $4.5 billion to $4.17 billion, after the Department of Public Utilities already reduced the proposed plan from $5 billion to $4.5 billion in February. For future three-year plans, the bill would cap Mass Save budgets at $4 billion.

The bill would allow customers to receive Mass Save rebates for gas furnaces and would undercut a demonstration project in the state that authorizes 10 municipalities to ban fossil fuels in new buildings and major renovations. Under the proposal, customers in municipalities participating in the demonstration project would be prohibited from receiving heating electrification incentives from Mass Save.

It also would remove the social cost of carbon from DPU and Mass Save calculations of cost effectiveness and would prohibit state entities from promulgating any regulations or programs that have “unreasonable adverse impacts” on energy costs or the “the operating costs or economic competitiveness of Massachusetts businesses.”

The House proposes authorizing the state’s electric utilities to enter long-term gas contracts, which could lift a major barrier to the development of new pipeline infrastructure into the region. (See Pipeline Expansion Highlights Key Questions About Gas in New England.)

Cusack’s bill would scale back the state’s Renewable Portfolio Standard, decreasing the required annual increase in the RPS from 3 to 1%. It would require the state to return to ratepayers 70% of alternative compliance payments made under the RPS.

Some aspects of the bill are aligned with clean energy priorities, including several provisions promoting surplus interconnection service and flexible interconnection. The bill would give the Department of Energy Resources increased procurement authority and set targets to procure 10,000 MW of solar and 10,000 MW of offshore wind by 2040.

Emissions Limits

Regarding the state’s five-year decarbonization targets, the bill includes language intended to prohibit any legal action against the state if the state fails to meet its 2030 emissions limit.

A 2021 law set the 2030 emissions limit at 50% below 1990 emissions levels. If emissions exceed the limit, the law requires the state to “describe remedial steps that might be taken to offset the excess emissions and ensure compliance with the next upcoming limit.”

While environmental advocates have strongly opposed efforts to undermine the state’s climate targets, interpretations vary regarding the extent to which the state is vulnerable to lawsuits for failing to meet its emissions limits, and limited legal precedent exists on the issue.

Sen. Mike Barrett, the top senator on the joint TUE committee, has stressed that the 2030 limit is “not a rigid five-year requirement, and no one has ever pointed to legal language that suggests otherwise.”

“The only hard and fast goal in Massachusetts law is net zero by 2050,” Barrett said in a conversation with RTO Insider in October. “The language is carefully written; if we fail to meet a limit or sublimit by 2030, we’re supposed to try extra hard to get us back on track by 2035 or 2040. I wrote that language, so I know what I’m talking about.”

Reactions

Environmental and consumer groups panned the bill, arguing it would gut the state’s climate laws while providing minimal cost benefits for ratepayers.

“This bill represents an attempt to undo decades of good climate policy in our commonwealth — policies and programs that many House members who serve with Chair Cusack spent blood, sweat and tears on,” said Vick Mohanka, director of Sierra Club Massachusetts.

Caitlin Peale Sloan, the Conservation Law Foundation’s vice president for Massachusetts, called the bill “nothing short of betrayal,” adding that “rolling back the state’s commitments to affordable, clean energy is a gift to polluters and a slap in the face to every resident who deserves better.”

Kyle Murray, the Acadia Center’s Massachusetts program director, said the bill fails to “meaningfully address many of the largest real underlying energy cost drivers,” including gas volatility, spending on gas distribution pipe replacements, electric transmission costs and utility profits.

Meanwhile, the Associated Industries of Massachusetts (AIM), the largest business association in the state, praised the bill.

“We applaud Chair Cusack and the House for boldly protecting Massachusetts consumers by offering meaningful reforms that will generate real energy cost savings at a time when everything is expensive,” said AIM CEO Brooke Thomson in a statement. “This legislation confronts the harsh realities of our climate policy decisions and ensures the commonwealth is set up for long-term success in meeting these climate goals.”

Cusack did not respond to multiple requests for comment.

MISO Interconnection Queue Dips Below 175 GW

MISO’s generator interconnection queue now totals 174 GW across 944 projects, a result of several developers dropping out of the line in recent months.

MISO Vice President of System Planning Aubrey Johnson told a Nov. 11 meetup of the Entergy Regional State Committee that MISO expects even more withdrawals as its planners begin processing studies. Johnson said many developers left the queue after the Trump administration announced it would abolish tax incentives for renewable energy development.

MISO’s queue has dropped steadily since the news. At the beginning of 2025, MISO said it had 312 GW to study; by September, that number had fallen to 215 GW. (See MISO Interconnection Queue Drops to 215 GW on Tax Incentive Phaseout.)

Johnson said MISO now expects to be able to sign 25 GW of interconnection agreements annually.

“We are moving projects through the interconnection queue; we are getting projects ready to come online,” Johnson said. He said MISO will work on the 2022, 2023 and 2025 cycles of projects; the RTO skipped the 2024 cycle while it designed a queue megawatt cap and put stricter rules in place to discourage developer speculation.

Between now and the second half of 2026, MISO estimates its members will add 8 GW of nameplate capacity (5 GW on an accredited basis) to the system.

Johnson said if achieved, those additions will exceed the 3.1 GW of capacity additions that MISO and the Organization of MISO States said were needed to meet the summer 2026 planning reserve margin. The shortfall prediction came from the MISO-OMS annual resource adequacy survey.

Johnson said as of November, MISO has 61 GW of projects with signed generator interconnection agreements that have permission to connect to the system.

Texas PUC Hints at Revisiting ERCOT Conservative Operations

Texas regulators have approved ERCOT’s methodologies for determining minimum ancillary services for 2026 while hinting at the same time that they are considering discontinuing the use of conservative operations (54445).

Potomac Economics, which serves as ERCOT’s Independent Market Monitor, has said the grid operator’s practice of setting aside large amounts of operating reserves leads to inefficient scarcity prices that the energy-only market relies on to attract investment. (See Patton Calls on ERCOT to Operate its System Less Conservatively.)

“I think we do need to look at moving away potentially from how conservatively we’ve been operating the grid,” Thomas Gleeson, chair of the Public Utility Commission, said during its Nov. 6 open meeting. “I think we need to talk through all that because we’ve committed to kind of having a refocus on affordability and costs. Every season we get away from [February 2021’s] Winter Storm Uri, I think we need to be asking ourselves, given where we are today, ‘Does our methodology, does our procurement practice, really match what we think we need?’ I think we need to start asking those questions.”

The PUC directed ERCOT to use conservative operations in 2023 after a flurry of conservation calls.

Commission staff said ERCOT’s current ancillary services and the future deployment of Dispatchable Reliability Reserve Service (DRRS) “provide ERCOT sufficient” ancillary service products to comply with NERC requirements and respond to “inherent system variability and uncertainty” (55845).

Staff recommended the PUC minimize the number of significant market design changes during the first several months after the Real-time Co-optimization + Batteries project goes live in December.

RTC+B will “likely produce a fundamental shift in the procurement and deployment of AS, and the industry will be best served if the commission observes those changes and uses RTC-based data to inform subsequent changes to future AS methodologies,” staff said.

The ERCOT Board of Directors endorsed the methodologies during its September meeting. The grid operator will use a probabilistic methodology — an analytical approach incorporating randomness and uncertainty by assigning probabilities to outcomes and events — to calculate hourly ERCOT contingency reserve service (ECRS) and non-spinning reserve service quantities. The probabilistic model aligns ECRS and non-spin requirements with the risk profile, where higher risk equals a higher requirement and vice versa. (See ERCOT Board Approves AS Procurement for 2026.)

The Monitor opposed the methodology during the stakeholder process, saying it was misaligned with reliability outcomes. The IMM’s compromise position included halving the six-hour forecast horizon for determining non-spin and using a one-hour discharge horizon for storage resources rather than four hours.

LCRA Wins 2nd TEF Grant

The commission approved the Lower Colorado River Authority’s eligibility for a Completion Bonus Grant (CBG) of up to $22.56 million in performance-dependent funds over a 10-year period under the Texas Energy Fund (57937).

PUC staff and LCRA signed the agreement Nov. 10, the first under the TEF’s completion bonus program for projects that connect to the grid before June 1, 2029. LCRA’s Timmerman Power Plant Unit 1 was synchronized in August.

Two other applicants in the program are seeking loans totaling $23.06 million, staff said, for projects offering a combined 360 MW.

“I think it’s fair to say this is working well,” Gleeson said.

The unit provides ERCOT 190 MW of dispatchable generation. A second unit is expected to become operational in 2026, adding another 190 MW of capacity to the grid.

Annual payments are contingent upon the plant’s performance as measured by ERCOT during an annual “test period” and compared to the performance of a reference group of other generation resources in the region. Timmerman Unit 1’s first test period will run June 1, 2026, to May 31, 2027.

The PUC announced in October the largest loan under the TEF’s In-ERCOT Generation Loan Program, a 20-year, $1.12 billion loan for about 60% of Competitive Power Ventures’ 1,350-MW natural gas unit in West Texas. The unit has a targeted operational date in 2029.

With the fifth grant under the program, the TEF has now financed more than 3,100 MW of dispatchable power. Twelve more projects are moving through the In-ERCOT program’s due diligence review, representing nearly 6,000 MW of additional generation.

PUC Approves ERCOT Budget

The commission endorsed ERCOT’s biennial 2026-2027 budget and system administrative fee, adding large load interconnections to a list of priority performance measures that must be met (38533).

As approved by the ERCOT board during its June meeting, the grid operator is authorized to spend $485.87 million in 2026 and $585.04 million in 2027. The PUC granted the grid operator’s request to increase an existing $100 million revolving line of credit by $25 million and to reduce its administrative fee from 63 cents/MWh to 61 cents. (See “Board Approves $1.07B 2-year Budget,” ERCOT Board of Directors Briefs: June 23-24, 2025.)

The large load performance measure was added to staff’s original recommendations, all designed to support ERCOT’s implementation of the 2026 reliability standard assessment: deployment and stabilization of the RTC+B project; enactment of Senate Bill 6, the 2025 legislation overhauling several grid regulations; development of DRRS; and implementation of the ancillary services study findings.

ERCOT staff agreed to work with PUC staff to develop the performance measure targets. “We have a lot of ideas,” General Counsel Chad Seely told the commissioners.

In other actions, the PUC:

    • adopted revisions to ERCOT’s standard generation interconnection agreement (SGIA) that require generators to pay interconnection costs that exceed a “reasonable allowance” established by the commission, effective Jan. 1, 2026. Other changes include revisions adding plain language and clarity to the SGIA; requirements regarding the sharing of contact information between generators and transmission service providers; and requirements that generators comply with the Lone Star Protection Act (58211).
    • approved an amendment to established wholesale market power rules that removes the exemption currently preventing a generation entity controlling less than 5% of ERCOT’s total installed capacity from being considered to have market power, commonly referred to as the “small fish rule” (58379).

Xcel Seeks Extension for Comanche Coal Plant from Colorado Regulators

Xcel Energy, along with Colorado Gov. Jared Polis’ administration, wants to keep Unit 2 of the coal-fired Comanche Generating Station running a year longer than planned, mainly because of malfunctions at Unit 3.

A petition filed Nov. 10 with the Colorado Public Utilities Commission asks to keep Unit 2 available through 2026, a year past its scheduled retirement date of Dec. 31. The petition was filed by the Colorado Energy Office, the state Office of the Utility Consumer Advocate, PUC trial staff and Xcel Energy subsidiary Public Service Company of Colorado.

The request follows the unexpected outage of Unit 3 that began Aug. 12. Xcel said the unit was extensively damaged and is expected to remain offline until at least June.

“The cause of the outage, the steps necessary to repair it and the costs are unknown at this time,” according to a fact sheet on the Colorado PUC website.

With a nameplate capacity of 750 MW and accredited capacity of 415 MW, Unit 3 is the largest of Comanche’s three units. It is to retire by Jan. 1, 2031. Unit 2 has a nameplate capacity of 335 MW and an accredited capacity of 296 MW, the petition said. The 335-MW Unit 1 retired in 2022.

The coal-fueled steam units are in Pueblo, about 110 miles south of Denver.

Extended Outage

Xcel’s petition to postpone the retirement of Unit 2 “is a direct response to the unexpected outage of the Comanche Unit 3,” the PUC fact sheet said.

But other factors are contributing to the request, the petition said. The peak demand forecast in PSCo territory has increased to about 7,150 MW for summer 2026. A forecast made in 2024 predicted the summer 2026 peak would be about 6,950 MW.

Supply chain and tariff issues are hindering generation and storage projects, the petition added. An updated analysis of accredited capacity showed that PSCo needs more generation and capacity to meet demand.

“The continued operation of Comanche Unit 2 in 2026 is the most cost-effective approach to providing needed electricity for the system,” the petition said.

While market purchases would be one option for replacing the lost output of Unit 3, “such purchases are often expensive and volatile, especially during high-use times, such as winter cold spells, which can lead to gas price spikes,” the PUC fact sheet said.

If the PUC approves a yearlong extension to Unit 2 operations, PSCo would report to the commission by March 1 on the status of Unit 3. The report would discuss short-term resource options and “appropriate operational parameters” for Unit 2, especially after Unit 3 returns to service.

A more detailed report would be filed by June 1, including updated load and resource projections and loss-of-load calculations. The six-month planning period would give PSCo time to propose longer-term resource options, potentially including “consideration of updated retirement dates for Comanche Unit 2 and Comanche Unit 3,” the petition said.

Cost Concerns

Unit 3 has been plagued with problems since operations began in 2010. From mid-2010 through 2020, the unit averaged 91.5 outage days a year, according to a March 2021 report from the PUC. A 2020 outage lasted much of that year and extended into 2021.

“Plagued by failures and outages, Comanche 3 has been an albatross around the neck of Xcel ratepayers for more than a decade,” Erin Overturf, clean energy director at Western Resource Advocates, said in response to PSCo’s petition. “This request to delay the long-planned retirement of Comanche 2 will lead to increased costs for utility customers at a time when people are already economically struggling.”

The Sierra Club said in a statement that any decision to keep a coal plant running for reliability reasons “must be strictly monitored and narrowly tailored to avoid more unnecessary costs and pollution.”

“The administration and Xcel’s proposal would guarantee only one thing: Comanche 2 will run for another year, which means more air pollution in Pueblo and higher electricity bills for everyone,” said Margaret Kran-Annexstein, director of the Sierra Club’s Colorado chapter.

The PUC approved early retirement dates for Comanche Units 1 and 2 in 2018. Xcel announced in 2022 its plans to exit from coal-fired power plants by the end of 2030 as part of its clean energy transition.

The Trump administration has had other ideas about coal plants set to retire. In late May, the Department of Energy issued an emergency order to reverse the impending retirement of the J.H. Campbell coal plant in Michigan. The order directed the plant to remain ready to operate because of a shortage of electricity and capacity to generate electricity.

DOE in August ordered Campbell to remain available through Nov. 19. In an Oct. 30 filing, plant owner Consumers Energy said Campbell had racked up $80 million in net costs since late May staying online. (See J.H. Campbell Tab Rises to $80M on DOE’s Stay Open Orders.)

UPDATED: Regulators Urge FERC to Honor State Authority over Large Load Interconnections

SEATTLE — The National Association of Regulatory Utility Commissioners passed a resolution urging FERC to resist the Department of Energy’s push to give itself jurisdiction over large loads interconnecting with the grid — an authority historically belonging to state regulators.

NARUC’s Board of Directors approved the measure (EL-1) in a Nov. 11 vote at the organization’s Annual Meeting.

The vote comes just over two weeks after Energy Secretary Chris Wright issued an Advance Notice of Proposed Rulemaking (ANOPR) pressing for FERC to extend its jurisdictional authority to include the interconnection of large loads — including hyperscale data centers. (See Energy Secretary Asks FERC to Assert Jurisdiction over Large Load Interconnections.)

DOE argued the new rules would be in the public interest and align with the Trump administration’s goals of reviving U.S. manufacturing and dominating the development of artificial intelligence.

But through the NARUC resolution, state regulators are asking FERC to “preserve and affirm states’ retail regulatory authority under the Federal Power Act” and “ensure that large load interconnections do not compromise grid reliability or impose undue costs on retail customers, and respect state tools for promoting system flexibility and equitable cost allocation.”

The resolution provides NARUC a foundation for developing initial comments on the ANOPR, Idaho Public Utilities Commissioner John R. Hammond Jr., chair of the group’s Committee on Electricity, told RTO Insider at the conference.

“We know the resolution is broad. We wanted it to be nimble,” said Virginia State Corporation Commission Judge Kelsey Bagot, who guided the document through the committee to gain consensus ahead of the board vote.

“We did get a lot of collaboration among NARUC members” on the resolution, Bagot said.

Hammond agreed that the group found a lot of “commonality” on the issue.

Comments on the ANOPR are due Nov. 21, which Bagot acknowledged is a “tight deadline.”

‘Unprecedented Expansion’

In an Oct. 23 letter to FERC accompanying the ANOPR, Wright contended that “the interconnection of large loads directly to the interstate transmission system to access the transmission system and the electricity transmitted over it falls squarely within the commission’s jurisdiction.”

The ANOPR offered a handful of legal justifications for the change, saying that:

    • large load interconnections are a critical component of open access transmission service that require minimum terms and conditions to ensure non-discriminatory transmission service;
    • interconnection of large loads directly affects FERC-jurisdictional wholesale rates, over which the FPA has granted the commission exclusive authority; and
    • the rule change would not violate state jurisdiction over retail sales.

The ANOPR also said that any views controverting the changes would conflict with the FPA’s core requirement that FERC have exclusive jurisdiction over transmission in interstate commerce.

But with the NARUC resolution, state regulators are clearly disputing those points.

A draft of the resolution said the proposed rulemaking “represents an unprecedented expansion of federal jurisdiction and potential intrusion on the states’ historic retail regulatory authority under the Federal Power Act, introducing potential confusion, unintended customer consequences and/or legal uncertainty where none currently exists.”

But the final resolution removed that language — and toned down other statements, instead saying “it is imperative that FERC, in any final rulemaking, make clear that it is affirmatively not asserting jurisdiction over end-use sales, which falls squarely within the exclusive jurisdiction of state retail energy regulatory authorities.”

The resolution goes on to explain that state regulators exercise oversight over resource adequacy, grid reliability and maintaining affordability for retail customers. It says their authority over integrated resource planning stems from their “reserved jurisdiction” under Section 201(b) of the FPA, “enabling states to oversee utilities’ long-term forecasting of electricity demand and evaluation of supply- and demand-side resources to meet that demand in a cost-effective, reliable and sustainable manner.”

The resolution notes also that NERC’s most recent Long-Term Reliability Assessment shows electricity demand is growing at the fastest rate in two decades, with especially steep increases expected for winter peaks. It cautions that “large load interconnections without sufficient available generation capacity could threaten reliable power service to existing retail customers,” with grid operators potentially lacking sufficient resources to maintain system stability during peak demand and extreme weather events.

The regulators warn also that the costs for large load interconnections, presumably mandated by FERC — including needed transmission upgrades — could unfairly fall to retail ratepayers “if not properly allocated.”

The resolution points out that at least “at least 20 states have approved or have pending large load tariffs or similar measures, which may include financial commitments, curtailment protocols and minimum contract terms to allow for the rapid interconnection of large loads without compromising grid reliability or unduly burdening existing retail customers.”

Drawing a Line

Judge Bagot expressed confidence that FERC can “find a solution states can be comfortable with,” noting the commission’s recent decision on Tri-State Generation and Transmission Association’s High Impact Load Tariff (HILT) could offer perspective on where the commission will stand.

In that order, FERC rejected the HILT, saying “certain aspects” of the proposed tariff “appear to present an impermissible intrusion on retail rate regulation” by state commissions. (See FERC Rejects Tri-State’s ‘High Impact Load Tariff’ Aimed at Data Centers.)

State regulators think “a line can be drawn” that preserves state authority but “allows the feds to be involved” with large load interconnections, Bagot said.

An earlier version of this article contained language from a draft version of the resolution. The story has been updated to reflect the wording in the final document.
