Nonprofits Warn of Potential TVA Privatization Ahead of Board Hearings

Environmental and social justice organizations have expressed concerns the Tennessee Valley Authority (TVA) could be headed toward privatization with a slate of board candidates assembled by the Trump administration.

The  nonprofit group Appalachian Voices is urging senators to question the four TVA board nominees’ intentions as to the sale of TVA’s publicly owned assets to private companies. The Senate Environment and Public Works Committee has a hearing Oct. 22 to consider board nominees. The nonprofit said it is concerned the potential new board composition could “sell TVA to the highest bidder.”

The Senate committee is due to consider:

    • Mitch Graves of Memphis, Tenn., a health care CEO who has served as a board member for Memphis Light, Gas & Water and maintains investments in multiple energy companies.
    • Jeff Hagood of Knoxville, Tenn., an attorney who has experience in criminal defense, injury litigation and representing university sports coaches and student athletes.
    • Randy Jones; Guntersville, Ala., an insurance executive who also serves on the Guntersville Electric Board.
    • Arthur Graham of Jacksonville, Fla., a member of the Florida Public Service Commission through Jan. 1, 2026, and a former city council member. If installed on the board, Graham would be the first TVA board member to live outside of states that contain TVA service territory.

Trump’s fifth nominee to the TVA board, businessman Lee Beaman of Nashville, Tenn., is not included on the agenda for the upcoming hearing and is expected to be considered later. Beaman is the former owner of a network of Nashville-area car dealerships and is a prominent Republican fundraiser.

For months, the nine-seat TVA Board of Directors has lacked a quorum. It contains just three members: Chair Bill Renick, Bobby Klein and Wade White. TVA requires five board members to establish a quorum and make decisions.

The Trump administration fired Biden-era appointees Michelle Moore, Joe Ritch and Beth Geer in the span from late April to mid-June.

The Trump administration previously proposed selling off parts of the TVA. During Trump’s first term, his team twice floated the idea to privatize some of TVA’s assets in budget requests for fiscals 2019 and 2020. At the time, the White House Office of Management and Budget reasoned that the private sector is better positioned to own transmission assets and that government ownership causes “sub-optimal investment decisions” and “unnecessary risk to taxpayers.”

Congress rejected both attempts.

So far in his second term, Trump hasn’t proposed the sale of TVA assets in a formal budget proposal. However, Appalachian Voices said it suspects the administration will pursue sales directly through the TVA board and CEO.

Appalachian Voices, along with Energy Alabama, the Sierra Club, Third Act Tennessee, Sunrise Nashville and multiple union organizations, hosted two virtual rallies Oct. 16 to urge the public to oppose TVA privatization.

In a press release, Appalachian Voices said it was apprehensive that the slate of candidates could sell off TVA’s assets. The group called the roster “largely unqualified” and said TVA needs “expertise on its board of directors, not pro-privatization auctioneers.”

“We urge senators to use this hearing and other conversations with the TVA board nominees to ensure they intend to keep TVA in the people’s hands, and to reject any nominees who don’t prioritize the interests of the people of the Tennessee Valley over billionaires and corporations,” Bri Knisley, director of public power campaigns at Appalachian Voices, said in a statement.

The Revolving Door Project, an executive branch appointee watchdog, said the Trump administration seeks to “stack the TVA governing board with a slate of nominees seemingly poised to do the bidding of his billionaire allies and corporate donors alike.” The group added that the Trump has “reinvigorated concerns over TVA’s privatization.”

TVA didn’t outright answer RTO Insider’s request for comment on possible privatization. Instead, the federally owned utility provided a fact sheet noting that it has fully self-financed through revenue from its electric sales since 1999 and does not contribute to taxpayer expenses.

“In fact, every year, TVA is a source of cash to the federal government, paying annual dividend-like return payments on the original investment in the power system,” TVA said. “The TVA model also results in savings every year for taxpayers across the country. TVA provides services that would otherwise be the responsibility of other federal agencies, such as river system management, flood control, navigation, land management and other related regional, multistate functions — without taking any annual appropriated funding.”

TVA said its management of reservoirs and recreation areas “serve as a driver for nearly $12 billion in total economic activity and more than 130,500 jobs.” It also said it “prevents more than $300 million in flood loss each year.”

NERC Preparing Workshop on FERC IBR Order

NERC is seeking comments on the agenda for a virtual workshop Nov. 5 in which the ERO will review its response to FERC Order 909, including a standards development project that aims to meet the commission’s directives by 2026.

The commission issued the order in July, approving new reliability standards establishing frequency and voltage ride-through requirements for inverter-based resources. (See FERC Approves IBR Ride-through Standards.) One of those standards, PRC-029-1 (Frequency and voltage ride-through requirements for IBRs), allows owners of legacy IBRs — resources already in operation when the standard goes into effect — 12 months after the effective date of the standard to request an exemption to its ride-through requirements.

Reacting to comments by industry stakeholders on its proposal to accept the standard (RM25-3), FERC directed NERC to clarify, within 12 months of the order’s effective date, what evidence it would accept to demonstrate hardware limitations for legacy IBRs. Also due in 12 months was a determination of whether any additional exemptions should be made for HVDC-connected IBRs with choppers — used in offshore wind projects to protect converters during grid faults — and other IBRs with long lead times “between adopting IBR specifications and placing the IBR in service.”

NERC’s workshop will outline the history of the project for industry stakeholders and solicit input on the issues entailed. Discussion panels are planned on documentation obligations for legacy IBRs and equipment limitations of IBRs with choppers that prevent them from complying with the ride-through standards of PRC-029-1.

In the final panel, participants will discuss how long-lead-time projects should be identified; whether they should be defined in the standard or left to industry to determine; potential equipment limitations from such projects; and solutions or workarounds that could address those limits. Attendees will also have the chance to provide feedback through live polling.

NERC staff have also suggested the workshop can help inform industry of relevant issues as stakeholders consider the standard authorization request (SAR) for Project 2025-05, which will handle the FERC directive. At the Oct. 15 meeting of NERC’s Standards Committee, Director of Standards Development Jamie Calderon suggested extending the comment period for the SAR — which begins Oct. 29 — from 30 days to 45 days in order to give industry more time to consider the discussion at the workshop. (See related story, NERC Standards Committee Passes Revised Proposals.)

In its announcement of the workshop Oct. 15, NERC invited stakeholders to provide input on the agenda. Topics of interest to the ERO include factual data on the exemption process, equipment limitations of IBRs with choppers and long-lead-time projects. Comments should be submitted by email to Alison Oswald, manager of standards development; Lauren Perotti, assistant general counsel; or Sarah Habriga, standards development analyst.

Hawley Asks Ameren if Ratepayers are Covering Data Center Costs

U.S. Sen. Josh Hawley (R-Mo.) has requested that Ameren explain whether its residential ratepayers are picking up the tab for grid upgrades necessary to accommodate data centers and other large industrial customers.

Hawley sent a letter to Ameren CEO Martin Lyons on Oct. 15 expressing concern that residential customers are shouldering cost hikes and facing shutoffs while Ameren “pursues expensive corporate projects.”

“Ameren is seeking dramatic rate increases in order to supply massive data centers and industrial users. Recent reporting indicates that Ameren cut electricity to thousands of Missouri households in September while simultaneously pursuing lucrative arrangements with corporate users,” Hawley wrote, adding that ratepayers should not be “forced to subsidize corporate projects while struggling to keep their lights on.”

Hawley was apparently referring to a report by KSDK in St. Louis that Ameren cut off power to 14,999 customers in September and 14,375 in August for nonpayment, according to Missouri Public Service Commission data. Meanwhile, Ameren told the PSC in late August that about 15 GW worth of load is under construction or being studied for interconnection in its service territory. It noted that included “organic load growth from residential, commercial and industrial customers, as well as new manufacturing and data center loads.”

The senator claimed that “Ameren’s current request before the Missouri Public Service Commission would raise electric bills for residential customers by roughly 15% — a staggering increase for families already squeezed by inflation.” He asked if this was because of the “considerable” power demands from new data centers. He also asked whether Ameren has analyzed how industrial contracts impact residential rates and if it has implemented protections to ensure that the infrastructure costs for large industrial customers are not passed on to residential customers.

“Has Ameren considered prioritizing rate stability for households before approving discounted contracts for data center clients?” Hawley asked. He added that he expected answers by Oct. 29.

Ameren Missouri does not have an open rate case. The PSC did grant the utility a $355 million rate increase in April, less than the $446 million it requested in 2024. The new rates took effect in June, with the average residential customer experiencing an approximate 11% increase (about $17.45) per month.

And Ameren has applied with the PSC to introduce new rates for data centers and other large loads. Commission staff have said that the utility’s plan lacks protections that would prohibit passing along the costs of new, expensive power plants to ratepayers and could raise electric bills by an estimated $22 million annually (ET-2025-0184).

“Captive ratepayers should not pay unreasonably for those upgrades, nor should existing ratepayers be caught having to pay for any potential stranded or under-utilized resources built to serve anticipated large load customers,” Missouri PSC Director of Industry Analysis James A. Busch said in testimony. Busch added that total electricity infrastructure costs could “easily exceed” $1 billion for just one large load customer.

PSC staff in September recommended that regulators reject the proposal.

In an email to RTO Insider, Ameren said it “obviously” disagrees with staff’s position and said it would file testimony to address the analysis. The company said its plan “aims to reasonably ensure large electric load customers pay their fair share of service costs, protecting other customers from unjust or unreasonable charges, in alignment with Missouri Senate Bill 4.”

That bill, which went into effect in April, contains a provision that large load customers cannot unjustly or unreasonably raise the costs of service for the remainder of a utility’s customer base.

Ameren also disputed Hawley’s worry that it would subsidize data center demand through residential bills.

“Data centers are required by law to pay rates that the Missouri Public Service Commission has determined reasonably cover their fair share of energy costs to serve them. Ameren Missouri is not offering these businesses any discounts. The infrastructure costs to connect large data centers to the grid are not passed on to other customers,” Rob Dixon, senior director of economic, community and business development, said in a statement to RTO Insider.

In previous testimony, Ameren Missouri Senior Director of Regulatory Affairs Steven Wills said the utility’s proposed large load tariff framework is “designed such that these large load customers are reasonably expected to pay their fair share over a long enough term to justify investment in long-lived generating assets.”

Under the plan, prospective customers with demand of 100 MW or more would enter into long-term electric service agreements for at least 15 years and be billed for a minimum of 70% of the contracted capacity listed in the agreement.

Wills said the terms of the large load agreements “ensure a reasonable level of revenues over a sufficient term to reasonably assure that other customers will not bear any unjust or unreasonable costs associated with the acceleration of new generation that will need to occur to integrate the loads onto the system.”

Ameren did not address Hawley’s inquiry as to whether it has analyzed how industrial contracts impact residential rates.

State-backed Actor Breaches Enterprise Software Product Security

Networking software and hardware developer F5 has suffered a major security breach by a nation-state threat actor that gained “long-term, persistent access” to information on the widely used BIG-IP product, the company said in an Oct. 15 statement.

BIG-IP is a family of hardware and software products that provide a range of services to enterprise customers, including cybersecurity, network load balancing and automation. F5 claims its products are used by 85% of the Fortune 500.

In its statement, F5 said the attackers gained access to company systems including the BIG-IP development environment and engineering knowledge management platform. The company admitted in a regulatory filing the same day that the intruders stole files containing portions of the BIG-IP source code and information about undisclosed vulnerabilities that F5 was working to address.

Also in the stolen files was “configuration or implementation information for a small percentage of customers.” F5 said it is still reviewing the files and will communicate with affected customers as needed. According to the regulatory filing, F5 learned of the unauthorized access on Aug. 9 but was allowed to delay disclosure for 30 days by the U.S. Department of Justice on Sept. 12 on the grounds that the revelation would present a national security risk.

The infiltration of a product development environment by nation-state actors is reminiscent of the SolarWinds hack of 2020, in which attackers — now identified by the U.S. as belonging to Russian intelligence agencies — accessed the update channel for SolarWinds’ Orion network management software and pushed code that could be used to gain access to customers’ systems. After that event, FERC ordered the development of new standards requiring internal network security monitoring at electric utilities. (See FERC Orders Internal Cyber Monitoring in Response to SolarWinds Hack.)

That similarity might be why F5 emphasized that it had seen “no evidence of modification to our software supply chain, including our source code and out-build and release pipeline.” It brought in independent cybersecurity research firms NCC Group and IOActive to validate this claim.

Those firms are also helping F5 with code review and penetration testing to identify and remediate vulnerabilities, the company wrote. Additional mitigation efforts underway include rotating credentials and strengthening access controls across all systems, hardening the development environment, and deploying improved inventory and patch management automation.

F5’s recommendations for its customers include immediately updating their BIG-IP software. The company issued downloadable updates in its quarterly security notification, but warned that only versions of software that have not yet reached their end of technical support phase will be patched. Other resources made available by F5 are threat hunting guides, hardening guidance with a verification tool, and threat monitoring tools.

The Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency (CISA), responding to the disclosure of the breach, issued an emergency directive ordering federal agencies to inventory their F5 products and apply updates to the affected software by Oct. 22. CISA also directed agencies to harden all public-facing BIG-IP physical or virtual devices and disconnect those that are no longer supported.

In CISA’s first press release since the federal government shutdown began Oct. 1, acting Director Madhu Gottumukkala said that “the alarming ease with which these vulnerabilities can be exploited … demands immediate and decisive action from all federal agencies.”

NERC and the Electricity Information Sharing and Analysis Center (E-ISAC) wrote in an email to ERO Insider that they were “not aware of any industry impact arising from the F5 vulnerability at this time,” but in the interest of caution, the E-ISAC sent an all-points bulletin to its members Oct. 15.

“The threat of cyber and physical attacks targeting critical infrastructure is not new, and ensuring a secure and reliable bulk power system is a top priority for NERC,” ERO staff wrote.

NOPR Would Get Pipelines to Offer More Information for Grid Operators

FERC has issued an official notice that proposes new standards for business practices that are meant to improve coordination between the electric and gas industries involved in interstate natural gas pipelines.

The proposal would incorporate the latest changes to Version 4.0 of the Standards for Business Practices of Interstate Natural Gas Pipelines adopted by the Wholesale Gas Quadrant of the North American Energy Standards Board (NAESB).

“Such coordination is essential to maintaining reliability for both the natural gas pipeline network system and the bulk electric system, especially during periods when both systems have coincident peak requirements,” FERC said in the NOPR. (The notice of proposed rulemaking is part of the FERC process required before issuance of a final rule.)

Better electric and natural gas coordination has been a priority for decades with FERC, NAESB and other entities making iterative changes as the interdependent, but much differently regulated industries, continue to evolve.

“I wouldn’t frame it quite like it’s never going to be done,” FERC Chair David Rosner said at the post-meeting press conference. “I would frame it more like — on Tuesday, we’re having our annual reliability conference, and if you look back at the arc of our reliability work, it’s constantly evolving. And so one thing that’s important to me is that we work with our expert staff and NERC and with our industry partners to make sure that as the world changes, as these sectors evolve, that we’re doing things that are smart and that are durable, and that make sense, and that solve problems ideally, before they become problems.”

The changes come out of a forum NAESB held at the request of former FERC Chair Rich Glick and NERC CEO Jim Robb “to identify actions that will improve the reliability of the natural gas infrastructure system as necessary to support the bulk electric system and to address recurring challenges stemming from natural gas-electric infrastructure interdependency.” NAESB set up its Gas-Electric Harmonization Forum to tackle those issues, issuing a final report in July 2023. (See NAESB Forum Chairs Push for Gas Reliability Organization.)

Other aspects come from FERC and NERC’s Winter Storm Elliott report, which included some recommendations on coordination that NAESB took up. The changes include one revised standard and two new ones.

The revised standard creates a central location on pipeline informational websites where they can post publicly available data such as scheduled quantity information. Now, pipelines will have a new information category: “Gas Electric Coordination,” which can help ISO/RTOs and other parties assess the data during extreme weather or emergency events.

The first new standard facilitates the posting of applicable scheduled quantity information for power plants that are directly connected to the pipeline as part of the “Gas Electric Coordination” category.

The second new standard supports the inclusion of geographic information of affected areas, locations and/or pipeline facilities by a transportation service provider when issuing a critical notice.

Commissioner Judy Chang filed a concurrence, lauding the work NAESB has done to improve gas-electric coordination with the new standards but urging continued work to improve communication between the sectors and to address remaining issues.

“The NAESB standards proposed here exemplify the type of brick-by-brick incremental improvements needed to address pressing gas-electric coordination challenges,” Chang wrote. “However, these proposed standards alone may not be enough to fully address the ongoing challenges.”

More information sharing will improve situational awareness for grid operators and generators, which will help when the systems are stressed. It might make sense to include information about gas scheduled for generators not directly connected to the pipeline system, she suggested.

“I further encourage continued collaboration between pipelines, suppliers, natural gas marketers and owners of upstream gas gathering systems to update pipeline operators and ultimately downstream gas users and electricity system operators of changes in system conditions, such as wellhead freezes, that could affect natural gas users and consumers,” Chang said.

She asked commenters in the NOPR process to suggest other changes that could improve coordination.

AEP Closes on $1.6B Loan Guarantee for Transmission Projects

American Electric Power has closed on a $1.6 billion U.S. Department of Energy loan guarantee to help finance 5,000 line-miles of transmission upgrades.

AEP Transmission will perform the work in Indiana, Michigan, Ohio, Oklahoma and West Virginia. It estimates the preferred interest rate deal will save ratepayers $275 million over the life of the loan while supporting economic development and technology advancements in the communities and regions served by the lines.

These benefits were emphasized by DOE officials as they announced the loan guarantee, which is the first closed under the Energy Dominance Financing Program created by the One Big Beautiful Bill Act in July.

“Energy is central to human lives in the United States and around the world,” Energy Secretary Chris Wright said during a call with reporters Oct. 16. “It’s not one sector of the economy; it’s THE sector of the economy that enables all the other sectors.”

DOE said electric utilities that receive loan guarantees under the DOE program must provide assurance they will pass along savings to their customers.

AEP provided a list outlining the 127 projects in the package. They range from a rebuild of 0.13 line-miles on the Comville-Cyril line in Oklahoma to work on 345 and 349.8 line-miles on segments of the Desoto-Sorenson line in Indiana.

In his remarks, Wright roundly criticized the energy policies of President Joe Biden and the financial support they offered for clean energy and decarbonization efforts. DOE’s Loan Programs Office — which has been renamed the Energy Dominance Financing Office — was central to this, Wright said.

Accordingly, DOE (like other federal agencies) has been canceling programs and funding central to Biden’s green agenda since President Donald Trump began his second term. (See DOE Terminates $7.56B in Energy Grants for Projects in Blue States and Energy Grants Worth $24B Appear Poised for Cancellation.)

But the review of these Biden-era awards — including AEP’s $1.6 billion loan guarantee, which was announced conditionally Jan. 16 — is showing that “not all of them were nonsense,” Wright said.

“The ones that are in the interest of the American taxpayers, in the interest of the American ratepayers, and there’s a helpful role for government capital, we’re happy to support those,” he said.

“We don’t care about authorship,” he told a reporter. “You’re right, this one started under the Biden administration, but it’s a good project. We’re happy to move forward with that. But, boy, there’s a lot [of projects] that don’t check those boxes.”

One of those was the Grain Belt Express, an $11 billion, 800-mile HVDC project under development since 2010. (See DOE Pulls $4.9B in Funding for Grain Belt Express.)

A reporter asked why DOE was backing AEP but not Grain Belt.

Wright said the AEP package is “a lot of bang for the buck” that will allow for better flow of power over existing lines to support economic development and reduce costs in five states.

Grain Belt, by contrast, will be slower and far more expensive per mile because it is new construction. Beyond that, it is a fundamentally different concept.

“Ultimately, that’s a commercial transaction, and it involves some market risk. Is that arbitrage big today, is that arbitrage still going to be big? Is it going to fund and pay off the construction of that transmission line? … It probably will, but it’s a more commercial enterprise that’s just done with private entrepreneurs and private capital.”

Greg Beard, who has been running what was known as the Loan Programs Office, added: “That project had a lot of merchant risk that was yet to be solved, and a consideration was: What’s appropriate for taxpayer risk and what’s appropriate for private market risk?”

Wright said: “I love energy infrastructure. I have nothing against the Grain Belt Express, I suspect it will still be developed.”

AEP hailed the agreement in a news release and said it will work with communities and landowners on siting the upgrades. CEO Bill Fehrman said earlier in 2025 that AEP will meet load growth with a capital spending plan totaling at least $54 billion. (See AEP to Meet Load Growth with More Infrastructure.)

He reiterated the growth in the Oct. 16 news release: “AEP is experiencing growth in energy demand that has not been seen in a generation. As the first company to close a new loan with the Trump administration under this program, we are excited to get to work on these projects to improve the service we provide to our customers.”

9-GW Power Gap Looms over Northwest, Co-op Warns

The Northwest faces a “pretty scary” situation, with a new study showing a potential 9-GW capacity shortfall by 2030, increased energy prices and building constraints, the Pacific Northwest Generating Cooperative’s (PNGC Power) CEO said Oct. 15.

Jessica Matlock, CEO at PNGC Power, told the Northwest Power and Conservation Council that a recent study by Energy and Environmental Economics (E3) predicts that accelerated load growth and aging power plant retirements will create a resource gap starting at about 1.3 GW in 2026 and expanding to almost 9 GW by 2030.

“That’s approximately the load of the state of Oregon,” Matlock said.

As is the case nationwide, data centers are the primary drivers behind the expected load growth. PNGC members already have 15 data centers seeking connection within their service territories, Matlock said.

“And we wonder, is that really going to materialize? Well, they actually already came in and bought all the property and got the permits from the county, and they’re breaking ground. So, it’s actually happening now,” Matlock said.

Matlock added that the data centers are the “mega ones. These are the big ones that you all hear the names of: Amazon, Meta.”

PNGC consists of 25 electric cooperatives spread across seven Western states. PNGC operates as a Joint Operating Entity, allowing the utilities to pool resources and share risks. PNGC also is Bonneville Power Administration’s largest preference customer, according to the co-op’s website.

“Traditionally, we get all our power from Bonneville, but it’s been clear that Bonneville is pretty tapped out of hydropower, and so the region is looking at this huge deficit,” Matlock said.

BPA’s power rate schedule consists of multiple categories of primary rates for federal energy sales, including Priority Firm Tier 1 rate, which represents most of BPA’s power sales. Tier 2 rates are for energy a utility obtains from the agency in addition to its contractual right to power at Tier 1 rates, according to BPA’s website.

The issue now, Matlock said, is BPA’s Tier 1 is fully allocated, and the agency must compete for power on the market “against tech companies and other IOUs … that have deeper pockets in Bonneville.”

In July, BPA published new rates in its final record of decision for the BP-26 rate period covering the 2026/28 interval. Under the new rates, customers’ power rates will increase by about 8 to 9% over the next three years, while transmission rates will jump by an average of nearly 20%. (See BPA Customers to See Increased Power, Transmission Rates.)

“It’s getting pretty scary,” Matlock said. “So, the price of Tier 2 power for Bonneville is going to go up, including Tier 1 power.”

BPA spokesperson Maryam Habibi noted that BPA has created a new methodology for post-2028 under new provider-of-choice contracts.

“We would set the Tier 1 amounts each customer is able to purchase under a calculation outlined in that new provider of choice policy through a process next year,” Habibi said. “We don’t yet know if we would need to augment our resources for Tier 1 or Tier 2.”

Meanwhile, generator resources in active development account for 3,000 MW of new capacity, 850 MW of which are coal-to-gas conversions and 350 MW are hydro upgrades, Matlock noted.

“The others are wind, solar, potentially biomass, a couple other different resources,” she added. “That is not going to get us to where we need to get to.”

Some states, like Washington and Oregon, have strict decarbonization policies, making it difficult to meet the new resource adequacy requirements many utilities will be subject to under the two day-ahead markets emerging in the West: SPP’s Markets+ and CAISO’s Extended Day-Ahead Market.

“For those states that are really confined to what they can develop — because you cannot develop natural gas in some of those — how are they going to meet these? We’re not sure,” Matlock said.

To meet the resource adequacy requirements with just renewable power “would require huge amounts of land.”

“We are developing solar and battery,” Matlock said. “That’s because we get additional capacity. We are continuing to talk to solar companies to develop that to shift to our Washington members. But the biggest problem for us to get this solar power to these members is the transmission system is too congested.”

She noted that PNGC is building a natural gas plant in northern Idaho from which it will ship natural gas to members in Washington state “to help keep the lights on.”

PNGC is exploring building transmission itself with the help of federal grants aimed at connecting data centers to transmission and then partnering with BPA on the buildout. The agency has paused certain transmission planning processes to clear the interconnection queue. (See BPA Transmission Pause Questioned During Workshop.)

“If we can’t get transmission to move solar, wind, natural gas, geothermal across the region to supply power to cities and towns, we are going to have a significant problem,” Matlock said.

Habibi said BPA does not build its own resources, but she noted that the agency has launched initiatives, such as the Grid Access Transformation project, which are “designed to improve access and streamline our processes for connecting resources.” She added that the new power contracts “add flexibility for customers to add new, non-federal resources. That flexibility does not exist today.”

FERC Approves SPP’s New Provisional Load Process

FERC has approved SPP’s tariff change to offer a provisional load interconnection process so the grid operator can study potential data centers and other large loads when there isn’t available power for the new facilities.

In an order issued Oct. 10, the commission accepted SPP’s proposal and directed the RTO to submit a compliance filing within 30 days. The order is effective retroactive to Aug. 4 (ER25-2430).

FERC said the new study process to evaluate requests for new loads when a transmission customer lacks sufficient existing “designated resources” to cover its 10-year load forecast (Attachment AX) will ease efforts to “appropriately and more expeditiously plan to serve their future loads.”

The tariff change will also allow the RTO to identify and address the effects of load additions by finding the resulting network upgrades on its system before sufficient designated resources are available, the commission found. It said the proposed pro forma provisional load process agreements for customers seeking network integration and point-to-point transmission services will provide just and reasonable terms and conditions for how SPP will study new load requests under the provisional load process.

SPP filed its proposed revision in June, saying that because it was seeing increased requests for new loads from data centers and industrial facilities, many transmission customers have been “unable to demonstrate sufficient existing” resources to serve their 10-year forecasts. It said Attachment AX will mimic Attachment AQ, the grid operator’s standard study process, except that it will consider a customer’s planned generation and its existing designated resources.

The RTO said the provisional load process captures the expected reliability effects of planned generation on the grid and will help the transmission customer plan for serving its future load.

Upgrade costs to interconnect new load will be assigned to the customer until planned generation is included in the transmission service agreement. Remaining upgrade costs will be rolled into regional rates.

The grid operator told FERC it has received just over 26 GW of interconnection requests larger than 100 MW since 2020. Data centers account for about 9 GW of those loads, the RTO said.

SPP stakeholders approved the provisional load process in April. It was later approved by the RTO’s state regulators and its board. (See “‘Chicken & Egg’ Issue,” New ERAS for SPP: Stakeholders Approve RA Studies.)

Battery Developers Seek Relief on IESO Ramp Limits

Storage developers in Ontario are pushing back on IESO’s 100-MW/minute ramp limit for batteries, saying it will reduce their revenues.

IESO said the limit is needed to allow it to meet NERC standards requiring balancing authorities to keep system frequency at 60 Hz.

“IESO has experienced negative impacts to system frequency resulting from the fast-moving capabilities of BESS [battery energy storage systems],” the grid operator said in a presentation Oct. 16 on its Storage and Co-located Hybrid Integration Project, which will introduce a single bidirectional resource model for BESS.

The initiative, part of the ISO’s Enabling Resources Program (ERP), initially will focus on electricity storage and hybrid generation-storage resources. It will replace the current two-resource model — which separates the withdrawal portion of the resource as load and the injection portion as a generator — with a single continuous offer curve. The current model creates operational challenges and reduces market efficiency, according to the ISO.

IESO plans to continue using its current 100-MW/minute up and down limit per facility under the new model.

3,000 MW of Storage Expected by 2028

The ISO noted that it expects 25 BESS facilities to join the grid in the near term, with about 3,000 MW of contracted storage expected in service by 2028.

IESO relies on regulation services to compensate fast output changes from batteries, said Ihor Lopuch, a project adviser. “In some cases, ISO control room operators have had to take additional out-of-market control actions, such as constraining some resources or sending one-time dispatches to help rebalance the system,” he said.

Storage operators first raised objections to the static ramp rates following an engagement session July 24. (See IESO Seeks Feedback on Revised Storage Model.)

In the most recent session, Travis Lusney, director of power systems for Power Advisory, representing the Energy Storage Resources Consortium, led the opposition. The consortium’s 12 members include Capital Power, EDP Renewables, Brookfield Renewables and Northland Power.

Lusney asked the ISO to determine the impact of increasing the ramp limit from 100 MW and whether there is an optimal limit that could maintain area control error while offsetting higher costs of regulation capacity. “Can it be 150, 200 [MW]?” he asked.

Lusney also asked for data on how often IESO will dispatch storage resources for operating reserves (OR) versus energy.

“The answer that I’ve gotten consistently is OR resources are … scheduled on the sideline to be there, but their dispatch instructions are only energy, and that there is no OR dispatch instruction,” Lusney said. “Part of that may have had to do with the previous market design, and that might be changed, but it’s not clear that there’s any historical information to understand how often an energy storage resource may receive an energy dispatch and be limited in that 100-MW/minute step up versus an OR dispatch that would allow them to ramp to their full capability.”

Lusney said battery operators face lost revenue because the limits negate the competitive advantage of their ramp speeds. “In a market design that encourages more price fidelity … this is quite restrictive on the competitive advantage of storage,” he said.

‘In Alignment’

IESO officials said the 100-MW limit is “in alignment” with other ISOs, including CAISO and SPP.

Tyler Chuddy, project superviser, said the ISO has limited analysis of batteries’ ramp impacts because it expects numerous BESS facilities to come online at the same time. “One hundred megawatts per minute means like a 500-MW shift in your production over one interval, which is pretty substantial,” Chuddy said.

He asked Lusney to provide details on how the ramp restrictions would result in lost revenue for battery operators. Lusney agreed to provide some examples from the consortium.

The current phase of the project, which may run as long as through 2028, will seek to establish the single resource model and set rules on state-of-charge management. Phase 2 will consider ways to allow batteries to also offer frequency regulation, which the ISO uses to correct supply-demand imbalances.

Lusney urged the ISO to consider batteries as a potential solution to the ramping challenges.

“If it’s a regulation capacity challenge driven by the fast response of the energy storage, can energy storage provide some of that regulation capacity in its dispatch instruction?” he asked. “[I recognize that] it’s not part of the current engagement process, but it seems like they are interconnected.”

Next Steps

IESO is seeking written feedback to its proposed rules by Oct. 30 deadline at Engagement@ieso.ca. The next engagement session for the project is expected in the first quarter of 2026.

NERC Standards Committee Passes Revised Proposals

In a busy meeting Oct. 15, members of NERC’s Standards Committee agreed to move forward with multiple high-priority standards development projects despite disagreements over details of the proposals from ERO staff.

First on the agenda was a standard authorization request (SAR) stemming from FERC Order 909, which in July approved new reliability standards establishing frequency and voltage ride-through requirements for inverter-based resources. (See FERC Approves IBR Ride-through Standards.)

PRC-029-1 (Frequency and voltage ride-through requirements for IBRs) permits owners of legacy IBRs — resources already in operation when the standard goes into effect — 12 months after the effective date of the standard to request an exemption to its ride-through requirements. FERC directed NERC to clarify within 12 months of Order 909:

    • acceptable evidence to demonstrate hardware limitations for legacy IBRs that would prevent them meeting the ride-through requirements; and
    • whether any additional exemptions should be made for HVDC-connected IBRs with choppers — used in offshore wind projects to protect converters during grid faults — and other IBRs with long lead times “between adopting IBR specifications and placing the IBR in service.”

A group of industry stakeholders developed the SAR and submitted it to FERC, NERC Director of Standards Development Jamie Calderon told attendees. Because the project originated from a FERC directive, the ERO has classified it as high priority. NERC asked the committee to authorize posting the SAR for a 30-day formal comment period and soliciting members of the drafting team for the project, which NERC has named Project 2025-05.

Asked by Claudine Fritz of Exelon whether NERC would reconstitute the drafting team for Project 2020-02 (Modifications to PRC-024 — generator ride-through), which developed PRC-029-1, to address Order 909, Calderon said while that team is no longer active, NERC has reached out to its former members to ask if any are interested in being involved.

Jamie Johnson of CAISO then asked if the comment period could be delayed until after a workshop on Order 909 that NERC is planning for Nov. 5. Johnson suggested this pause could “provide more insight for potential revision to the SAR.”

Calderon expressed concern that delaying the start of the project might leave the development team pressed for time. However, in light of the fact that the comment period is expected to start Oct. 29, she suggested extending its length to 45 days. She said this move would allow commenters to consider the issues discussed at the workshop before giving their feedback. Johnson moved to update the proposal with this extension, and committee members approved it unanimously.

Supply Chain, IBR Proposals Pass

Another FERC directive was next on the plate, as the SC took up a SAR addressing the commission’s order Sept. 18 that NERC develop standards addressing supply chain risk management (SCRM) plans by May 21, 2027. (See “Supply Chain Standards Due in 18 Months,” FERC Tackles Cybersecurity in Multiple Orders.)

The new standards must address the sufficiency of entities’ SCRM plans as they relate to identifying and responding to supply chain risks, as well as whether they apply to protected cyber assets (PCAs), defined as “one or more cyber assets connected using a routable protocol within or on an electronic security perimeter [ESP] that is not part of the highest-impact [grid] cyber system within the same” ESP.

NERC asked that attendees approve the SAR’s posting for a 30-day informal comment period and authorize soliciting drafting team members for 15 days. Members voted unanimously to accept a motion to do so.

Also approved without objection was a proposal to appoint the slate of members recommended by NERC for Project 2025-03 (Order 901 operational studies). This project addresses the fourth and final milestone of FERC Order 901 by establishing requirements for registered entities to perform “operational studies for registered IBRs, unregistered IBRs and [distributed IBRs] in the aggregate.”

However, a proposal to approve members for a project addressing Order 901’s requirement for planning studies met with concerns from committee members about the fact that it contained two candidates from the same company. Paul MacDonald, of the New Brunswick Energy and Utilities Board, said that while he was “typically very supportive” of NERC’s recommendations for drafting team composition, he would prefer to see one of the candidates — who were not identified by name during the meeting — removed from the list.

Conferring privately, NERC staff agreed to drop one of the candidates, after which MacDonald moved to approve the updated list. This motion passed unanimously.

The committee’s last standards action was to authorize drafting new or modified standards to allow PCAs, electronic access control or monitoring systems (EACMS) and physical access control systems (PACS) together in a single standard, a move intended to bring clarity to NERC’s enforcement process. SC members previously agreed to post the SAR for this project for a 30-day formal comment period; NERC Manager of Standards Development Alison Oswald said the SAR has been revised in accordance with the comments received through that process.

Finally, SC members voted to endorse NERC’s 2026-2028 Reliability Standards Development Plan (RSDP), which sets out “time frames and anticipated resources for each project under development or anticipated to begin” within the next three years. The RSDP will be presented to NERC’s Board of Trustees in December, and then to FERC for final approval.
