CAISO on Oct. 7 described to stakeholders how it will apply the Extended Day-Ahead Market (EDAM) transmission revenue recovery mechanism to its own balancing authority area.
The mechanism, referred to as the EDAM access charge, will allow transmission owners (TOs) to recover transmission revenue shortfalls attributed to transitioning their assets into the day-ahead market.
The access charge was the only provision of CAISO’s initial EDAM tariff proposal that FERC rejected last December, finding the ISO failed to justify the reasons behind the three components constituting the charge. CAISO revised the plan and it was accepted by the commission in June. (See FERC Approves EDAM Tx Revenue Recovery Plan.)
During the Oct. 7 meeting, CAISO staff gave an overview of how the access charge could be applied within the ISO through an explanation of the plan’s three components for calculating and recovering lost revenue after launch of the EDAM.
The first component allows TOs to recover historical transmission revenues associated with wheeling access charge (WAC) revenues.
“When an EDAM entity joins the EDAM, the intertie point becomes a transfer point between the ISO and that EDAM entity, and there may be an impact on wheeling access charge [WAC] revenues that were historically recovered across that intertie,” Milos Bosanac, CAISO regional markets sector manager, said at the meeting. “This component 1 allows for the recovery of those historical WAC revenues at that particular intertie to the extent that there’s an impact.”
The WAC revenues eligible for recovery under the mechanism will be based on a three-year average of revenues prior to that transfer point becoming an EDAM point, Bosanac explained. The draft tariff revision states that each TO will be responsible for calculating the first component.
Heather Curlee, senior counsel at CAISO, dove into the draft tariff language to implement the access charge in the ISO and provided additional details on the plan’s components.
The second component seeks to compensate TOs for costs “associated with forgone transmission sales on eligible existing contracts or [transmission] upgrades” that potentially increase the transfer capability between EDAM areas. Recovery of those costs would again require analyzing the three-year historical average of recovered revenues on a particular EDAM transfer point and comparing it to the overall ratio of the total transmission revenue requirement within the BA.
According to the tariff, a participating TO with existing contracts will calculate the second component, to include revenue shortfalls associated with the release of transmission capacity resulting from expiring existing rights not included in the first component.
The third component centers on compensating CAISO TOs for EDAM wheel-through transfers that provide benefits for other parts of the market footprint.
The draft tariff revisions say that in periods when the total volume of EDAM wheel-through transactions exceeds the total net transfers of the CAISO BA, the ISO will calculate by multiplying its share of the excess volume based on its individual share of transmission revenue requirements in relation to total transmission revenue requirements for the CAISO BA.
CAISO will distribute to gross load in the ISO BA each EDAM access charge allocated to its BA, according to the proposed tariff revision.
The ISO plans to file the draft tariff language with FERC in November.
ERCOT CEO, State Rep Preview 2025 Texas Legislative Session
AUSTIN, Texas — The Gulf Coast Power Association again reported a record attendance — just over 800 — for its annual Fall Conference held Sept. 30 to Oct. 2, with discussions on the industry’s future, emerging grid technologies and Texas’ 2025 legislative session.
ERCOT CEO Pablo Vegas and state Rep. Todd Hunter (R) — chair of the House State Affairs Committee, which oversees the Texas grid — kicked off the conference with a fireside chat that included their expectations on the 89th Texas Legislature, which convenes Jan. 14.
“Here’s the bottom line for all the questions I get every place I go: labor, water, power. I bet I get contacted every two to three weeks by new groups coming to look at Texas,” said Hunter, often referred to as “The Man in Black” around the Texas Capitol for his wardrobe choice. “So what’s on the legislative agenda? One, I think you will see a push by the legislature to do what we can to increase power resources. Texas, I think, is the fastest growing state. The demands are huge. And what does that mean? Water, labor and power.
“The message from me: What’s on the plate is to do everything we can meet the needs.”
Vegas said ERCOT works “incredibly closely” with Hunter’s committee and that there isn’t a “big gap” operationally between what the grid operator has and what it will need for the next few years. The sessions that followed Winter Storm Uri of February 2021, he said, “have set us up for the growth trajectory that’s in front of us.”
“One thing that maybe we’ll spend a little bit of time on is talking about how to best manage the influx of different types of large loads that are coming to Texas,” Vegas said. “That’s something that is an evolving and changing dynamic. … Whether it’s data centers; whether it’s hydrogen developers; whether it’s the electrification that we’re seeing out in the Permian [Basin], there’s going to be a wide variety of opportunities to work with these customer groups to find ways to help them grow reliably and rapidly, because Texas does have one of the most fertile environments for economic growth. I think we’re going to be really well positioned for a constructive legislative session.”
Moderator Barbara Clemenhagen, GCPA executive director, asked whether ERCOT will continue its post-Uri conservative operations posture in which it sets aside several thousand megawatts each day to respond to tight situations. Vegas responded that as an “energy island,” the grid operator can’t lean on its neighbors to protect a “flagship competitive market that is studied and looked at very closely around the world.”
“This competitive market works, and I believe that it can work in the changing environment that’s coming our way,” Vegas said. “We have one of the most dynamic set of resources that are providing energy; that can come and go and fluctuate their intermittency on the wind and solar side. We need to have a lot of these reserve resources to be able to manage that because we can’t lean on anyone else. This is what we have to do in order to ensure we can be reliable on a regular basis. I don’t believe consumers or stakeholders are comfortable with living on the edge of a grid that could be an emergency condition on a regular basis.”
ERCOT Deals with Uncertainty
ERCOT’s Dan Woodfin, vice president of system operations, said the pace of change in generator types has been so “tremendous” that the ISO’s operators are having to learn a new system every six months.
“Operators like to have rules of thumb about how they operate,” he said. “A couple of years ago, we had a lot of wind and a little bit of solar. Last summer, we had more solar and a few batteries. And this year we have more solar and more batteries. And next year, we’re going to have twice as much solar, potentially, and a lot more batteries. That means every six months or so, we throw away all our rules of thumb and we’re operating a new system.”
Woodfin said four issues must be considered in adapting the grid to new technologies: adequacy, uncertainty, variability and stability.
“If you’re involved in the ERCOT stakeholder process, you will recognize those things as being the underlying factors behind most of the major debates that have gone on in the last year or so,” he said. “Managing the sunrise and sunset ramps is going to become increasingly critical. Now, the increasing number of batteries help manage other resources’ variability, but then we have to make sure we’re not overly depending on them beyond their inherent limited duration.
“There’s also the managing of the uncertainty because some of that we can predict. I’m pretty good at predicting when the sun’s going to come up and when the sun’s going to go down every day,” Woodfin continued. “But as we get more wind and solar, even if we’re driving down the percentage error in terms of our forecast, the errors continue to grow with the additional installed capacity. So there’s just a lot of variability and uncertainty growing.”
PUC Exes Praise SPP
A panel of former Texas regulatory commissioners shared their perspectives on recent shifts in energy policy and offered their thoughts on improving the stakeholder process and communications between ERCOT’s Technical Advisory Committee and the Board of Directors.
“What’s the right way to kind of think about efficient, inclusive and successful [relationships]?” asked Pat Wood III (1995-2001). He noted recent comments by Public Utility Commission Chair Thomas Gleeson that the interaction between the board and TAC “did not work” for him. (See “Members Discuss Stakeholder Process,” ERCOT Technical Advisory Committee Briefs: Sept. 19, 2024.)
“There’s a disconnect, seemingly, between all these arguments that are happening at TAC and what the board eventually deliberates on,” said Will McAdams (2021-2023). “But I believe we don’t need to reinvent the wheel. Other ISOs have crossed this Rubicon before.”
McAdams offered SPP’s Members Committee as an example. The 23-person committee, comprising several different stakeholder segments, debates issues and provides an advisory vote for the board before the directors cast their ballots.
“The Members Committee is a great tool … and none of this requires statutes, by the way,” McAdams said. “I think it could be self-adopted, but … some type of equivalent organization that may not be empowered to have a binding vote … where the board will see the arguments from the industrial segment; the industry segment; the utility segment. They’ll know exactly what they’re getting into with their vote.”
“I 100% agree with that,” Pedernales Electric Cooperative CEO Julie Parsley (2002-2008) said as Brandy Marty Marquez (2013-2018) nodded her head in agreement.
“SPP has been great because they sit at the table; they argue,” Parsley said. “They vote, right? But they’re not the controlling vote. They just vote, and then the independent board members vote. [The members are] in front of them. They’re not off in some committee room at TAC, so they hear it all, and it’s really great.”
Marquez, McAdams and Parsley all represented Texas on SPP’s Regional State Committee.
DOE’s Biddle Spotlights Clean Energy
Bearing what she called “the longest title in the world,” Leslie Biddle — the U.S. Department of Energy’s deputy under secretary for commercialization and finance — issued a call to action for utilities, regulators and the rest of the industry to “rethink our go-to solutions” for adding new generation.
“So how do we do that in a way that addresses the baseload needs?” she asked her audience. “I’m so excited to be here because we do also need to change the culture; we need to use things differently than we have in the last couple decades. For a few decades now, we’ve been using the same labor to build centralized generation and associated transmission and distribution to meet those long-term human needs. It worked … but we haven’t really had to innovate, and we haven’t had to adopt new ways of working, and we will.”
Case in point: DOE’s latest in a series of liftoffs reports, Pathways to Commercial Liftoff. Thanks to the Infrastructure Investment and Jobs Act and the Inflation Reduction Act, the department is positioned to invest billions of dollars in large-scale demonstration and deployment of clean energy technologies it says will be needed to meet rising demand.
Biddle pointed to a slide that listed more than $6 billion in investment for two dozen awards for projects in Texas and Louisiana. They included $1.2 billion to X-energy to develop gas-cooled reactors and another $1.2 billion for a hydrogen hub involving Chevron, ExxonMobil and Air Liquide, among others.
“We expect this all to be built in the next four years,” she said. “Our capital goes in currently for the development stage.”
DOE says it expects 15 to 20% growth in demand over the next decade and for it to double by 2050, driven by economic development and electrification.
“It’d be hard to say that we aren’t surprised about the electricity demand growth over the next decade, when you’re telling everyone that they should electrify. That’s what happens,” Biddle said. “From our perspective, growth is good. It means that we’re bringing in more manufacturing jobs, and we’re expanding our leadership and innovation and expanding artificial intelligence and expanding access to more efficient clean growth in America. It will require a change in the way we invest and manage our system. Fortunately, we have the technologies and the solutions we need to meet the growing demand.”
AI as Savior for Clean Energy?
DOE could find help in reaching its net-zero-emissions goals from an unlikely source, according to several panelists discussing artificial intelligence.
“I’m going to say something slightly controversial, but I feel that AI and the computing power and all of that, even though in some ways it’s consuming more … we need AI to get us to net zero because of the sort of second-by-second optimality that we need,” said Erin Boyd, chief digital commercial transformation officer for AES. “All of the data goes into getting more out of our assets and finding better locations and managing demand and supply just down to that sort of microsecond.
“Even though everybody says, ‘Oh, AI is driving up energy demand,’ it’s an interesting problem where I’m not so convinced yet that that’s the case. I believe that AI is actually what’s going to get us to net zero and a situation where we’re actually consuming less, but also consuming energy that’s uncertain; that’s fickle, that you know can’t be managed.”
“I’m also very upbeat about the potential for AI,” said Venkat Tirupati, ERCOT’s vice president of DevOps and grid transformation. “I look at it from two different angles. The first angle is just on grid operations and market operations. There are definitely things that will help us to be more efficient to run markets very well. But if I look at ERCOT as an enterprise, there are a lot of productivity gains that we could get by just embracing AI into the everyday.”
PUC’s Roth Gets Award
The GCPA honored the PUC’s Werner Roth with its emPOWERing Young Professional Award, presented annually to individuals under the age of 40 who have demonstrated excellence in the electric power industry, made unique contributions to the power market’s success, and served as a role model and leader for others.
Roth, a senior market economist in the market analysis division, has worked at the commission for more than 10 years. He holds bachelor’s and master’s degrees in economics and another bachelor’s degree in chemical engineering.
“I have often wondered how a young graduate without experience in the electric markets could develop such deep and wide skills for power markets,” said Harika Basaran, the division’s director. “Then I realized that he did most of it on his own initiative.”
Roth thanked the commission’s leadership for allowing him to “lean in on a lot of the projects that have focused on a lot of issues in the ERCOT process and, more importantly, have enabled staff to [provide] perspective on those
The proposed reliability standard to require ride-through protection for inverter-based resources (IBR) cleared a major hurdle last week by passing a formal ballot round after multiple previous attempts to get it over the finish line ended unsuccessfully.
Now the way is clear for NERC’s Board of Trustees to vote on it and four other standards whose passage is required to meet FERC’s deadline of Nov. 4 to submit the first of three tranches of IBR-focused standards. Those votes are set to take place at a special board meeting scheduled for Oct. 8.
The formal ballot for PRC-029-1 (Frequency and voltage ride-through requirements for IBRs) concluded Oct. 4 with 158 votes cast in favor of passage and 50 votes against (with comment); 59 ballot pool members either abstained or did not vote. After applying NERC’s segment weighting, which lowers the impact from segments with fewer voters, the final result is a 77.88% weighted segment value supporting passage, comfortably above the two-thirds majority needed for passage.
Failing to meet the two-thirds threshold would not necessarily have prevented PRC-029-1 from passage. Under Section 321 of the ERO’s Rules of Procedure — invoked for the first time by NERC’s board at its August meeting — the standard could have been considered approved with a 60% segment-weighted majority. (See “Board Invokes Standards Authority to Meet IBR Deadline,” NERC Board of Trustees/MRC Briefs: Aug. 15, 2024.)
In that case, the board would have had to solicit written public comment on the proposed standard. If satisfied the standard was just, reasonable, not unduly discriminatory or preferential, and in the public interest, it then could file it with FERC.
The Section 321 authority also required NERC’s Standards Committee to conduct a technical conference to solicit input from industry stakeholders. At the technical conference, held Sept. 4-5 in Washington, D.C., representatives from a range of industry segments — including original equipment manufacturers and utilities — discussed their objections to the proposed standard. (See NERC, Industry Discuss IBR Issues in Technical Conference.)
Following the conference, NERC revised the standard to address attendees’ concerns, including the clarity of the definition of “ride-through,” criteria for frequency ride-through performance and exemptions to ride-through criteria for equipment with hardware limits. Most stakeholders commenting on the revised draft felt the changes reflected opinions expressed at the conference, though many also felt more could have been done to accommodate concerns.
In a long comment, Jens Boemer of the Electric Power Research Institute said the new draft standard “appears to be improved” and expressed appreciation for the standard drafting team for taking the comments of EPRI and others on board. However, he also indicated “further improvements” would be welcome, including:
further clarification of the definitions of IBRs and the term “ride-through,” and specific grid conditions for which the ride-through requirements apply.
guidance for determining the maximum capability of an IBR.
exemptions for legacy equipment that may be challenging to update because of lack of manufacturer support.
At its meeting Oct. 8, NERC’s board will vote on submitting PRC-029-1 to FERC for approval, along with the other IBR standards approved in previous ballot rounds:
PRC-024-4 — Frequency and voltage protection settings for synchronous generators, Type 1 and Type 2 wind resources, and synchronous condensers.
PRC-028-1 — Disturbance monitoring and reporting requirements for inverter-based resources.
PRC-002-5 — Disturbance monitoring and reporting requirements.
The board also will consider accepting revisions to the charter of NERC’s Reliability and Security Technical Committee (RSTC) that are intended to improve the balance of industry representation at meetings. The new rules will allow a sector to seek a special election to fill an open seat representing it, rather than have that seat convert to an at-large member as the current charter provides.
In addition, they will remove the numerical cap on the number of representatives from a sector that can serve as at-large members and will direct the RSTC Nominating Subcommittee to prioritize balanced sector representation.
FERC has issued a deficiency letter over SPP’s proposed revisions to its tariff, bylaws and membership agreements intended to facilitate nine western entities’ RTO membership as transmission owners.
In an Oct. 3 letter, the commission said SPP’s filings are deficient and that it needs more information to process them. It asked the grid operator to submit its responses by Nov. 4 (ER24-2184, ER24-2185).
FERC asked for more information on:
Any existing tariff provisions that will facilitate the transition of the new members’ transmission service request queues into SPP’s current service-study processes.
The proposed tariff’s provision that the Western Area Power Administration-Colorado River Storage Project’s replacement energy is “necessitated by WAPA-CRSP’s inability to deliver sufficient energy from reservoir projects under the control of the U.S. Bureau of Reclamation in the marketing area of WAPA-CRSP for reasons such as persistent drought or environmental constraints.”
New metered boundaries and the need to establish a second balancing area authority that will be incorporated into SPP’s markets.
How separate reference buses in the market’s two balancing authority areas will accurately model the marginal cost of serving load in each BAA, including the cost of congestion.
How LMPs on both sides of the West DC ties will inform how SPP optimizes the interties’ usage.
Which rate(s) under the tariff revisions would apply to point-to-point transmission service where the load is located within a BAA external to the SPP Region but not interconnected to SPP’s eastern or western market.
SPP filed the tariff for its western RTO expansion in June as it seeks to become the first grid operator with markets in both the Western and Eastern Interconnections. It says its RTO West will provide more than $200 million in annual benefits to its members. (See SPP Files to Incorporate Western Entities into RTO.)
RTO West is scheduled to go live in April 2026.
FERC also filed a deficiency letter for SPP’s Markets+ tariff, another of the RTO’s western services. Saying deficiency letters are part of a “routine process, SPP staff responded to the letter in September and asked for an order by Nov. 20. (See SPP Dispels Concerns over Markets+ Deficiency Letter.)
NYISO on Oct. 4 released the first draft of its 2024 Reliability Needs Assessment (RNA) showing a capacity deficiency in New York City beginning in 2033 and proposing to declare a reliability need for its zone.
The deficit is driven by a combination of forecast increases in peak demand and the looming retirement of small gas plants in the city, NYISO said. The analysis found that on a peak summer day with expected weather conditions (95 degrees Fahrenheit), the city would be deficient by 17 MW for one hour in 2033, rising to 97 MW for three hours in 2034.
“This is based on the transmission security analysis and the feeding into the transmission security margin,” Ross Altman, senior manager of reliability planning for NYISO, told the Electric System Planning Working Group. “This is an actionable reliability need.”
The declaration of a reliability need triggers a process in which NYISO solicits solutions, including transmission-based from the local transmission owners, and generation and demand response from market participants. The ISO declared a short-term reliability need for the city last year, finding a potential 446-MW shortfall by 2025. It later decided to keep two natural gas peaker plants, collectively 565 MW, in Brooklyn operational beyond their state-mandated retirement as a solution. (See NYISO to Keep Gas Peakers Online to Solve NYC Reliability Need.)
The assessment assumes those units to no longer be available beginning in 2026. The state also recently enacted legislation to retire seven small New York Power Authority gas-fired plants in the city and Long Island worth 517 MW by the end of 2030.
“The reliability need could be met by combinations of solutions, including new generation, retention of planned generation retirements, transmission, energy efficiency, demand response measures or changes in operating protocols,” the draft says. “Specifically, scenarios performed in the RNA indicate that the New York City transmission security deficiency could be resolved by resources currently under development but not yet in the base case.”
NYISO had reported the possibility of such a deficiency for the city, but it had been overshadowed in meetings by a preliminary finding of a statewide shortfall of as much as 1 GW by 2034. The ISO, however, updated its assumptions about the flexibility of large loads — specifically, cryptocurrency mining and hydrogen-producing facilities — which reduced its loss-of-load expectation to less than 0.1.
Still, the ISO warned in its draft that the LOLE is “extremely close” to the maximum: 0.094. “The tightening margins are a significant concern that … NYISO will closely monitor and re-evaluate in future [Short-Term Assessments of Reliability] and the next cycle of the Reliability Planning Process.”
“We are just under a violation, and a big factor of that is the treatment of large loads,” Altman said.
Large Load Flexibility
Several stakeholders questioned how NYISO determined how certain large loads would be flexible and criticized the lack of any data on the topic.
“In your evaluations, did the cryptocurrency load representatives — whatever they are called — give you any idea about how much notice they would need to curtail their load?” asked Mark Younger, of Hudson Energy Economics.
Altman said he did not know and that he did not want to get too detailed on what NYISO discussed with the cryptocurrency companies because such information was “proprietary.”
“They provided enough information that [made NYISO] feel they would be flexible, either sensitive to prices or demand response,” Altman said. NYISO did not forecast the price of Bitcoin or other cryptocurrencies, he said.
“For other resources, whether it’s SCRs [special-case resources] or generators, … NYISO has tariff provisions and other goals that require submission of information so you guys can track what’s going on,” said Kevin Lang of Couch White. “This is the only place I can think of where there’s absolutely nothing — no reporting requirements, no obligations — … and yet from the tables you’re showing us, if these loads continue to operate during peak periods, we have a very significant problem.”
“We are engaged in bilateral discussions and surveying with these large loads in terms of the nature of these large loads and their intention to operate,” said Tim Duffy of NYISO, explaining that operating procedures and interconnection studies were also sources of information. “NYISO is really reliant upon transmission owners to gather that data.”
“I appreciate the explanation, but I just think, given how critical this is to your assumptions, that there should be something more formalized with these loads,” Lang replied.
Tight Deadlines, Annoyed Stakeholders
Stakeholders expressed numerous criticisms of the draft’s publications, including the lack of an executive summary: The opening section simply says “Reserved for future drafts.”
They were also annoyed that NYISO released the draft on a Friday, with multiple stakeholder meetings scheduled that day, with a deadline for comment the following Monday (Oct. 7).
“I am going to bust your chops,” Younger said. “The ISO needs to be rethinking the timeline that they hope that market participants can provide useful feedback on this, given how late it came out and also given that it came out at the same time that many of them are dealing with a critical step in the Demand Curve Reset, a timeline that was well known in advance.”
Several sections, including those detailing the New York City reliability need and the narrowly avoided statewide need, were worded confusingly, stakeholders said.
“My personal opinion is that NYISO has bungled some of the communication efforts around recent reliability reports,” said Chris Casey, utility regulatory director for the Natural Resources Defense Council. “I think it’s important for us to have time to be able to not only understand what the data and findings are, but make sure the narrative matches reality. I don’t think we were given time to do that here.”
Doreen Saia of Greenberg Traurig requested that NYISO allow more time for discussion at the working group’s meeting Oct. 9.
“We are going way too fast on an area that is completely charting new ground,” Saia said.
Lang pointed out that NYISO had provided executive summaries on previous RNA reports for 2018, 2020 and 2022.
“You are going way too fast, and you aren’t giving market participants sufficient time to understand what’s really going on here,” Lang said.
Dramatic spikes in New Jersey electricity bills over the summer stemmed from the combined effects of an unprecedented heat wave and recent rate increases, utility executives said at a state Assembly hearing.
Electricity use in June and July shot up by 15 to 20% in some areas over the same period in 2023 in what the New Jersey Board of Public Utilities (BPU) said was the hottest June on record.
The Oct. 2 Assembly hearing also spotlighted the need to better cope with the state’s growing need for electricity and how to bring new generation sources online to replace retired fossil fuel sources.
The hearing came as Gov. Phil Murphy (D) pursues an aggressive energy policy centered on electricity and the development of 11 GW of offshore wind capacity. Republican lawmakers argue the state is moving too fast and should embrace a broader energy portfolio.
The Assembly Telecommunications and Utilities Committee convened the hearing in response to widespread customer complaints about the sudden increase in the size of their bills.
“I received countless calls from my constituents because they are seeing what I have been seeing — skyrocketing electric bills,” Assemblywoman Andrea Katz said in testimony to the committee. “I heard it from my neighbors, and I saw it on my own electric bill. Utilities like Exelon have seen their stocks up 10% over the last year, while at the same time, families in New Jersey are paying hundreds of dollars more a month for their electric bills. … And we all need answers.”
BPU President Christine Guhl-Sadovy said the “main driver of the increases over the summer was an increase in usage.”
Customer use across the four utilities that serve the state — PSEG, Jersey Central Power & Light, Atlantic City Electric (ACE) and Rockland Electric Co. — increased by 12 to 16% over the previous year, which was relatively cool with unusually low use, she said.
In addition, she said, the BPU certified a rate hike that would increase the average customer bill by 5 to 8% due to electricity rates set in the Basic Generation Service (BGS) auction held by the four utility companies.
Multiple Rate Hikes
Brian O. Lipman, director of the New Jersey Division of Rate Counsel, said the rate hike was one of several implemented by utilities that affected customers for whom, given the elevated temperatures, “air conditioning is no longer a luxury, it is life saving.”
In testimony, and in a supporting letter to the committee, he said ACE had increased rates nine times since July 2023, and reduced rates four times, for a net overall increase. These included increases for transmission rates, infrastructure improvements, and prices set by the BGS results, which increased electricity supply rates by about $7.56 per month, he said.
Even before the use increase, the average ACE ratepayer was paying about $23.64 more in June 2024 than a year earlier, Lipman said.
Add during the heat wave and “the result is significantly higher bills for ACE customers in the summer of 2024 as compared to the summer of 2023,” he said in the letter. “This analysis does not only apply to ACE. I could go through the same analysis for PSE&G, JCP&L and Rockland Electric Co.”
Speaking at the hearing, Phil Vavala, ACE’s regional president, said the average customer bill increased by 20%, part of which was due to the “pass-through” cost of electricity rates, which are set at the BGS auction.
He said the company works to “empower customers to better manage their energy use.” That includes providing customers with programs that “help those who are struggling to meet their energy needs” and to deploy smart meters that enable customers to better monitor their energy use, he said.
Electricity Demand Surge
Several speakers said the spike in customer bills showed the state has to address far larger systemic issues.
“One of the main takeaways that we probably will all share today is that we do need more generation,” Guhl-Sadovy said. “We, over the last couple of decades, have not seen a significant demand increase in energy use, in part because we’ve done a really good job in energy efficiency. And so we’ve helped to keep that demand flatter. But we have seen energy demand go up, and so we do need more generation.”
BPU officials said at an Oct. 1 hearing into the agency’s offshore wind infrastructure solicitation that they expect demand for electricity in the state to increase by 15,000 GWh to 93,000 GWh by 2025. (See related story, NJ Offshore Infrastructure Plans Spark Electromagnetic Fears.)
Jason Stanek, executive director of PJM Interconnection, which serves 13 states, said the region is in the midst of a transition.
“We’re seeing a tightening of supply and an increase in demand,” he said. “And they’re going in opposite directions relatively quickly.”
He said the RTO’s load forecast released earlier in the year showed trend lines that were “head and shoulders above all prior years.” That increase stems in part from the rise in electric vehicle use and the emergence of commercial high-energy users such as data centers and artificial intelligence facilities, he said.
An example of the challenge facing PJM, he said, is that in the 12 months prior to the summer of 2024, the RTO experienced 4,000 MW of generating source retirements, while peak demand rose by 4,000 MW.
“So that’s an 8,000-MW difference in just a short period of 12 months,” said Stanek, adding that such a sudden increase in demand is difficult for PJM to handle. A shortfall in supply compared to demand can increase the price of electricity. That was demonstrated in the results released in July of the organization’s recent capacity market auction, which set electricity prices nearly 10 times higher than a year ago, he said.
Stanek urged lawmakers to help PJM, and the region, better handle the ongoing demand surge by avoiding policies that are “designed to push resources off the system before we have an equal and equivalent amount of replacement resources.”
At the same time, PJM is working through a backlog of customers waiting to connect new sources to the system, he said.
Things got a little testy at the NYISO Budget and Priorities Working Group meeting Oct. 2 when Cheryl Hussey, the ISO’s chief financial officer, presented some final updates to the proposed 2025 budget.
Hussey said NYISO was proposing to increase the Rate Schedule 1 carryover to $5 million. In September, Hussey explained that the ISO is expecting a surplus this year because of overcollections under RS1, the administrative rate used to recover operating costs from members. (See NYISO Proposes Increased Budget, Admin Rate for 2025.)
“That’s really the only change to the actual budget itself to date,” said Hussey, who went on to explain that this would reduce the budget to $202 million, a $2 million decrease from what she previously presented. This would result in an RS1 surcharge of $1.306/MWh instead of $1.319/MWh. Hussey said that higher projected overcollections were being used to reduce RS1 instead of paying outstanding debt.
“Can you share your analysis that shows that this is actually in the customers’ best interest to use this money as a one-time carryover rather than paying down debt?” asked Kevin Lang, a lawyer representing Multiple Intervenors and New York City. “We had pushed for paying down debt years ago because we understood at that point in time that that was really the best use of it. … I don’t see any analysis at all. I just see a statement here.”
Hussey said the interest rates NYISO was paying on its debt were quite low and that the numbers were just projections but that if NYISO had extra funds they were able to use them to pay down debt early.
“If stakeholders would rather us not have a carryover to reduce next year’s budget, that’s fine. I’ve asked for that feedback,” Hussey said.
“I’m not asking for that, Cheryl. I’m simply asking for the analysis you guys did,” Lang said. “We’re paying for all of this. You guys aren’t a confidential entity, and you’re saying you’ve done an analysis that shows this is the best use. I’m not saying, ‘Don’t do it.’ I’m simply saying I’d like to see the analysis so we can better understand that.”
Hussey said NYISO would need to review its agreements with its banks to see what information she could share.
Lang replied that he had seen more detailed budgets from other grid operators and suggested that if NYISO wasn’t willing to share more detailed budgetary information, then perhaps it was time to revisit auditing its management.
“I know you’ve been completely opposed” to an audit, Lang said. “But the [New York Public Service Commission] has that authority. The FERC has that authority. Maybe it’s time that we take a closer look at some of these issues.”
Hussey said she was not refusing to share the analysis, but Lang retorted that she had not agreed to provide it, either.
How to Value Transmission Security
The Installed Capacity Working Group meeting Oct. 1 was dominated by a discussion of the different ways that NYISO could incentivize transmission security via the markets.
The Market Monitoring Unit and several stakeholders have raised concerns about how transmission security requirements are incorporated into the ICAP market at minimum levels. The worry is that the current market structure does not correctly incentivize or value transmission security, leading to repeated regulatory and public policy interventions to build out the transmission system. (See “Demand Curve Reset and Transmission Security,” NYISO ICAP Working Group Briefs: Sept. 24, 2024.)
But how to value transmission security is an open question.
“We would have separate requirements, curves and accreditation for resource adequacy and transmission security, priced separately,” said Manish Sainani, NYISO market design specialist, outlining the Monitor’s proposal.
“You’ve just described something that’s drastically more complicated than having separate requirements and doing a joint solving program,” said Mark Younger, principal of Hudson Energy Economics. “It seems what you’re proposing is an even bigger kludge than what we have in the market today.”
Later in the discussion, NYISO clarified that its presentation was just trying to identify potential options but that none of them had been decided on yet.
“It seems like one of the first things we should try to nail down is the methodologies for calculating TSLs [transmission security limits] and [locational capacity requirements]; that’s been underway for a while,” said Mike Mager, a lawyer from Couch White representing large energy consumers. “I don’t think it makes a ton of sense to change the market for TSLs when we’re not even positive what the methodology is for calculating them.”
Monitor Pallas LeeVanSchaick said TSLs are having a major impact on the market.
“It’s having a big impact today, and it’s going to have a bigger impact in the future,” he said. “I think our proposal was just trying to make a refinement to the market so that it is having an appropriate impact.”
HOUSTON — Returning to the “scene of the crime,” as Houston state Sen. Molly Cook (D) put it, the Texas Public Utility Commission made a rare trip out of Austin for a public hearing as it investigates CenterPoint Energy’s heavily criticized response to Hurricane Beryl in July.
The Category 1 storm appeared to catch CenterPoint off-guard and knocked out power to more than 2 million of its customers. The Houston utility was excoriated for its poor communications, an outage map that didn’t work and lack of outreach to the community. At least 40 deaths have been attributed to the storm, many related to the extreme heat (indexes reached 106 degrees) during the outages that extended into a second week. (See CenterPoint Energy Still in Eye of the Storm.)
Texas Lt. Gov. Dan Patrick (R), a Houston-area resident since 1979, was not on the agenda but opened the Oct. 5 hearing with 30 minutes of prepared remarks. Saying he had no “personal animus” toward CenterPoint, CEO Jason Wells or anyone on the commission, Patrick suggested the utility needs a new leader and threatened the PUC with using the Senate’s subpoena power to conduct its own investigation.
“CenterPoint should have been prepared three and four days after that storm hit Houston, and they were not,” Patrick said. “We were at the state level. They were not. Had they been prepared, I believe much of the misery and damage after the fact would have been averted.
“So, it’s not personal, Mr. Wells. We’ve had good discussions, but CenterPoint needs to have a strong leader who will have foresight, not look back in the rearview. ‘Oh, we’ll fix it now,’” he said. “I believe at this point, the board of CenterPoint should ask for Jason Wells’ resignation, or I believe he should submit it.”
Patrick noted he returned home from California several days before the storm’s July 8 landfall when it became apparent Beryl would hit Texas. A National Weather Service representative backed him up, testifying that the agency had a tropical storm warning in effect July 6 and then expanded it to inland warnings.
“It was a terrible wind event that brought down the trees and power lines and traffic lights. We know all of what happened, but [CenterPoint was] slow,” Patrick said. “They were slow in preparation, procrastination and then communication. People didn’t know where to turn. No one could get a response. It was the poorest response to citizens and elected officials trying to reach them.”
Citing state rules, Patrick said the PUC has the right to audit and review CenterPoint’s management and business operations. Consumer advocates have said the utility has been overcharging customers for years.
“I expect you to do that audit,” he said. “I want to know how much they have been overcharging, if they’ve been overcharging the customers at CenterPoint, and for how long. We need that answer.”
The lieutenant governor also upbraided the PUC for its approval of 2021’s $800 million lease of generators, some designed to restore power to entire neighborhoods but that weren’t used in Beryl’s aftermath. The commission approved CenterPoint’s cost recovery — about $350 million so far —over an administrative law judge’s recommendation.
“If the commission doesn’t act on the $800 million, if they don’t act on the right cases, if the commission does not act on looking [into whether customers] have been overcharged, then our [state Senate] Business and Commerce Committee will be given subpoena power to get the answers,” Patrick said.
“I want to know about that $800 million. I want to know why it was signed … I want to know why it was overturned,” he continued. “If the PUC allows CenterPoint to get away and try to PR their way through this, that will show the commission is not accountable.”
As lieutenant governor, Patrick controls the Senate’s agenda. Two of the PUC’s commissioners, Chairman Thomas Gleeson and Courtney Hjaltman, have not yet been confirmed by that legislative body.
“I know how personal this is to you,” Gleeson told Patrick when he wrapped up his comments. “Thank you for your leadership, and I know you’ll continue to hold this commission and everyone accountable to make sure we get the right results.”
About six hours after the hearing began and some 30 local residents had complained about CenterPoint, Wells took the stand and “personally” apologized to those still present.
“The number of outages [was] too high, the … outages were too long, and our communications did not meet your expectations,” he said. The CEO said CenterPoint has not been overcharging customers and frequently earned less than it could have.
Darin Carroll, CenterPoint’s senior vice president of operations, provided an update on the utility’s Greater Houston Resiliency Initiative to better prepare for the next major storm or hurricane. CenterPoint expects to spend about $550 million during the plan’s current phase on 25,000 poles that can withstand extreme winds and undergrounding 400 miles of lines, among other items.
The company plans to invest $5 billion in the Houston system between 2026 and 2028. It will file a long-term plan by Jan. 31.
The PUC also discussed best practices with industry veterans of previous hurricanes, including two former Florida Power & Light employees, and representatives from the Edison Electric Institute and the Southeastern Electric Exchange. Florida has been held up as a positive example of grid hardening following eight major storms in two years.
The commission will continue to take customer feedback through Oct. 9. It will file its report and recommendations for changes to Gov. Greg Abbott and the legislature by Dec. 1.
“We heard loud and clear that you expect better from your electric utility, and we plan to use your feedback to ensure Houston-area utilities are prepared the next time extreme weather hits,” Gleeson said after the hearing in a statement.
The CAISO Board of Governors on Oct. 4 unanimously approved changes to the Southwest Intertie Project-North (SWIP-N), a 285-mile, 500-kV line in Nevada that would enable access to Idaho wind resources, despite opposition from Gem State residents.
In April, the Department of Energy signed a facilitation agreement to provide $33.1 million to fund Idaho’s potential 22.831% share of the project to expedite the process. CAISO had asked the board to approve two motions: to allow the DOE funding, and to approve project developer Great Basin Transmission’s application to become a participating transmission owner in the ISO.
The project would enable CAISO to meet the California Public Utilities Commission’s Integrated Resource Plan requirements, which call for just over 1,000 MW of Idaho wind power in the 2024-2025 transmission planning cycle. According to transmission planners at the ISO, SWIP-N is the only known transmission project that would provide California load-serving entities with Idaho wind by 2027.
While SWIP-N was conditionally approved by the board in December 2023, moving to the construction phase still relied on the approval of the two motions.
“Unlike a project directly assigned to an incumbent transmission owner under the Transmission Control Agreement, this did not move the project straight to execution,” Neil Millar, vice president of infrastructure and operations planning at CAISO, said at the board’s meeting.
Deb Le Vine, executive director of infrastructure contracts and management at CAISO, presented details on the status of the project, as well as the two motions. The project was initially approved under four conditions: that Idaho Power file and receive approval for the project with the Idaho Public Utilities Commission by Sept. 30; that the California PUC reaffirm the need for Idaho wind in its 2024-2025 transmission planning process portfolio; that Great Basin declare its intent to become a PTO by July 1; and that FERC accept Great Basin’s proposed tariff and transmission revenue requirement rate structure.
Idaho Power has not yet filed with the Idaho PUC, meaning that FERC has not yet approved Great Basin’s tariff. The other two conditions were met.
“It’s critical to enable Idaho wind to reach California, consistent with the CPUC system plan,” Le Vine said.
Opposition from Idaho Residents
While SWIP-N isn’t tied to any specific generators in Idaho, some residents opposing the Lava Ridge Wind Power project and others in the region expressed concern about SWIP-N.
Dan Sakura, a fourth-generation Japanese American whose ancestors were interned at the Minidoka War Relocation Center in Idaho — a National Historic Site — said the area is now located in a “dense transmission network” because of its proximity to a railroad. Sakura, along with the Seattle-based Minidoka Pilgrimage Planning Committee, has been fighting LS Power since 2009 when it sought to build the SWIP-N line over the site. The organization is also fighting the Lava Ridge Wind Project, which it believes to be associated with SWIP-N.
Sakura asked the board to delay its decision until its meeting in December to allow for more time to “get a better analysis of the legal, regulatory, policy and electoral risks associated with wind energy from Idaho.”
Another Idaho resident, Dean Diamond, a farmer whose property borders the Minidoka site, echoed Sakura’s concerns.
“There is a lot of strong local opposition to the SWIP line and to the wind projects. I think that it poses a really significant risk that the wind projects most likely aren’t going to be built,” Diamond said.
“We’re not aware of that high opposition, just an attempt from those against the wind projects to link SWIP-N to that,” responded Mark Milburn, senior vice president of LS Power. “I think it’s also important to address that the commenters thus far haven’t acknowledged that in [the Bureau of Land Management’s] preferred alternative for the final environmental impact statement for the Lava Wind Ridge Project, they significantly scaled back the project to address the concerns raised by different stakeholders in that process.”
Milburn noted that the project footprint was reduced by 50% and the number of turbines by 40%, along with a 10% reduction in turbine tip height.
Board Chair Jan Schori thanked the commenters for participating in a process that “can be quite challenging to understand.”
“We do appreciate the fact that you’re participating with us today and helping educate us,” Schori said.
The D.C. Circuit Court of Appeals has affirmedFERC’s ruling that NextEra Energy is responsible for replacing the circuit breaker at its Seabrook Station nuclear plant to accommodate the interconnection of the New England Clean Energy Connect (NECEC) transmission line.
ISO-NE determined the circuit breaker at Seabrook, currently at 99.6% of its capacity, would be overloaded with the additional flow of power from Avangrid’s 1,200 MW NECEC project, which is under construction. (See Avangrid Details Progress on NECEC Tx Line.)
While FERC found Avangrid is responsible for the direct costs of upgrading the circuit breaker, it ruled Avangrid is not responsible for NextEra’s indirect costs of the replacement, including legal expenses and revenue lost during the replacement.
“We hold that the agency had statutory authority to require the upgrade, correctly interpreted the governing tariff and contract to require the upgrade, and permissibly denied compensation for its indirect costs,” Judge Gregory Katsas wrote in the court’s Oct. 4 ruling.
The court found the upgrade is FERC jurisdictional because “the upgrade directly affects the transmission of electricity in interstate commerce, an area where FERC may regulate.”
“If FERC could not order an upgrade in those circumstances, incumbent generators could unilaterally prevent competing sellers from joining the grid, which would directly — and substantially — limit how much electricity could be transmitted,” the court added.
The court also pointed to a previous ruling that backed FERC’s ability to “exercise jurisdiction over generation facilities to the extent necessary to regulate interstate transmission.”
Judge Neomi Rao authored a dissent to the majority ruling, arguing the language in the ISO-NE tariff does not require NextEra to replace the circuit breaker, and therefore the company should not be required to make the upgrade, regardless of the implications on interconnection in the region.
“The broader regulatory context and policy concerns cited by the majority may be relevant to FERC’s determinations when setting just and reasonable rates and practices. These considerations, however, are impermissible for the judicial task of identifying the plain meaning of existing tariffs and contracts,” Rao said. She added that FERC could initiate a Section 206 proceeding to amend the tariff if it deems changes to be necessary.
Rao also argued the majority opinion “reverts to a Chevron-like framework, insisting its interpretation is ‘textually permissible’ and consistent with regulatory goals.”
In response, Katsas wrote that the RTO’s interconnection procedures require NextEra to follow “good utility practice” to maintain the breaker and other devices needed to prevent short-circuiting on the grid, adding that the tariff does not grant NextEra “a unilateral right to veto Avangrid’s interconnection.”
