ERCOT IMM Raises Concerns over Newest Ancillary Service

ERCOT’s Independent Market Monitor says the grid operator’s recent implementation of its first ancillary service in 20 years has nearly doubled the amount of required online reserves, resulting in “enormous” increases in market costs and shortage pricing when the market is long.

Carrie Bivens, the IMM’s vice president, told stakeholders Friday that procuring and deploying the ISO’s newest ancillary service (AS), ERCOT contingency reserve service (ECRS), has reduced supply and liquidity in the day-ahead market and “significantly” raised demand for AS products. That has resulted in inefficient day-ahead AS price spikes, she said.

“We’re seeing a disconnect between the operational realities and the pricing outcomes,” she said during a Wholesale Market Working Group meeting. “It’s also causing reliability issues, in our opinion, by increasing the challenges with managing congestion because fewer megawatts are available for scheduled dispatch to manage congestion … we’ve seen that on a few days you’re seeing a huge increase in market costs.”

AS services have incurred $1.56 billion in costs this year through August, Bivens said. ECRS, which began June 10, is responsible for almost 39% of those costs, or just over $608 million.

She said while the costs are substantial, they are much lower than the effects of removing the additional reserves from real-time market dispatch. Increasing online reserve procurements with ECRS “likely” raised the real-time market’s energy value by $8-10 billion in three months, Bivens said.

“Price spikes in the day-ahead market are not necessarily reflective of the underlying conditions,” she said. “The huge costs that we are really keying in on are the ones from [the] real-time market by removing those reserves. Taking megawatts that would have been available for energy dispatch and making them unavailable is reducing the supply available … that is causing this increase in real time energy prices, even though we have tons of reserves.”

The new AS is economically dispatched within 10 minutes of deployment, using capacity that can be sustained at a specified level for two consecutive hours. ECRS essentially meets the same reliability requirements that previously were met solely by responsive reserve service (RRS), the IMM pointed out.

ECRS has resulted in a 2,500-MW increase in online reserve procurements, moving the MWs behind the high ancillary services limit (HASL). Bivens says that has resulted in artificial pricing shortages when total reserve levels are high and a negative effect on congestion management, as more MWs needed to address congestion are reserved for ECRS or RRS.

She said the artificial tightness is “episodically mitigated” by the operators’ deployments, which interferes with day-ahead market decisions, whether to self-commit resources in real time and resource offers — all of which are based on expectations of real-time prices.

IMM staff arrived at the $8-10 billion figure by simulating the real-time energy market with reconstructed offer curves for lower ECRS procurements. Their analysis cleared the input MW quantity at the generation requirement’s original SCED execution. Once a baseline scenario was done, staff modeled incremental 25% releases of ECRS in subsequent scenarios and calculated energy cost reductions.

Real-time ECRS deployments were maintained so that none of its additional capacity was released if deployments exceeded the release percentage. The simulation did not model congestion, ramp limitations, controllable load resources’ dispatch or the power balance penalty curve.

“We wanted to show is this a small problem or is this a big problem?” Bivens said. “This is an order of magnitude type of analysis and what this is showing is that indeed it is a large problem.”

Jeff Billo, ERCOT’s director of operations planning, pushed back against Bivens’ presentation and the IMM’s call for a holistic review of ECRS, among other recommendations. He acknowledged inefficiencies and additional market costs but said ERCOT is getting the reliability it needs.

“When I look at the data that was presented, I don’t see anything that backs up those recommendations other than ancillary services are really expensive or they’re causing outcomes in the market that are really expensive. I don’t see any data showing that we’re getting more than we actually need,” he said. “I also don’t agree with the term artificial scarcity because this is a reserve product that we are buying, so it is meant to be held in reserve. It’s not artificial, it is on purpose. We are reasonably reserving megawatts that we may need for various conditions that may occur on the system.”

“I think we just want to make sure that you’re buying what you need to be reliable, and no more than that,” Bivens responded. “And also, I think we need to ask the question of the ECRS that we got this summer, ‘Was it worth $10 billion?’ That’s something that I think I would ask people to think about.

“A lot of these megawatts, particularly during the summer, they’re going to be online anyway,” she added. “All you’re doing, and why I’m calling it ‘artificial scarcity,’ is you’re taking megawatts that would have been online for energy and putting them behind the HASL. And that’s what’s causing the cost increase. It’s not that we’re getting more megawatts. It’s just how we’re treating them.”

The IMM recommends ERCOT reduce the ECRS’ two-hour duration requirement to a single hour to encourage more storage participation. Its other recommendations include:

    • Reducing ECRS’ frequency recovery MW procurement;
    • Removing the 2,800-MW floor on RRS;
    • Changing the non-spin error requirement from six hours ahead to three; and
    • Using 10-minute ahead net load errors for ECRS methodology.

The recommendations are based on the 2023 AS methodology and will be updated when ERCOT staff publishes its 2024 for the services, Bivens said.

The Texas grid operator launched ECRS in June. It was the first daily-procured ancillary service introduced to the market in more than 20 years.

ECRS’ development began as a protocol change, approved in 2019, designed to address forecasting errors from the increased penetration of renewable resources or to replace deployed reserves. The change also modified responsive reserve service to be primarily a frequency response.

FERC OKs MISO Removal of Annual Reviews for Long-term Tx Projects

MISO is off the hook for having to conduct annual cost-benefit analyses of its major transmission projects, FERC has ruled.

FERC on Friday allowed MISO to cut the portion of its Tariff requiring it to conduct annual benefit reviews of its long-term transmission projects. The RTO still will conduct its more comprehensive triennial reviews (ER23-2478). The commission’s approval was effective Sept. 24.

FERC said it was persuaded the annual reviews “have become less useful over the years given the development of alternative sources of similar information.” The commission said it didn’t think the discontinuation of the reviews would affect project transparency in MISO.

In July, MISO proposed eliminating the four limited annual reviews required of it for long-term transmission projects. That will leave the RTO conducting two triennial reviews of projects following project approval. It said the move will “drive administrative efficiency for MISO, its stakeholders and regulators.”

According to MISO, removing the limited reviews will allow it to spend more time planning portfolios of other long-range transmission projects. It also said the annual reviews usually only uncover “minimal data changes” year-over-year and said info on transmission projects’ progress is available to stakeholders on its website, through its Transmission Expansion Plan (MTEP) quarterly status updates and contained in its variance analyses. MISO performs variance analyses on projects only when they materially change in cost, schedule or design from MISO approval.

MISO’s triennial review requires it to calculate economic benefits of major projects, such as congestion and savings and the ability for the RTO to carry a smaller amount of reserves. It also requires MISO to evaluate achieved public policy targets, like the amount of new renewable energy the line can bring to the system, and perform five-year historical examination of the line’s effect on the fleet mix, interconnection trends, energy prices, fuel costs and margin requirements.

On the other hand, the limited reviews required MISO to calculate the latest data available of the economic benefits and five-year historical trends.

The Organization of MISO States supported the pruning of reviews, saying its remaining reporting requirements are sufficient to stay up to date on transmission projects. However, the group of state regulators requested FERC order MISO to “consistently and accurately” update its long-range project dashboard and quarterly status reports on its MTEP portfolios to ensure they’re useful. OMS said MISO has been inconsistent in updating actual project costs and in-service dates, which limits regulators’ ability to question transmission developers’ cost containment efforts.

FERC, however, said the OMS concerns were beyond the scope of the proceeding and declined to address them. MISO said FERC should disregard the OMS request because it’s already working to upgrade its admittedly outdated MTEP project portal, the database it maintains for approved projects.

NYISO Stakeholders Discuss Enhanced Regulations for Information Sharing

RENSSELAER, N.Y. — NYISO soon could significantly tighten its security and information protection requirements, according to a presentation given to stakeholders last week.

Troutman Pepper, an energy law firm, advised the Transmission Planning Advisory Subcommittee and Electric System Planning Working Group meeting that as digitization grows, enhancing NYISO’s critical energy and electric infrastructure information (CEII) protection has become increasingly important.

Kat O’Konski, an associate at Troutman Pepper, said, “there is a pressing need” to improve CEII requirements because both “physical and cyber assaults on the grid are at a record high.” (See Feds Charge Idaho Man in Dam Attacks; NERC’s Cancel Details Grid Threats to House Energy Subcommittee; DERsDeployment Leads to Increasing Cyber Threats.)

Troutman wants to toughen measures around NYISO’s data dissemination by requiring third parties working with and around the ISO’s supply chain to implement more stringent protocols for CEII sharing and access.

These enhancements include mandatory cyber-training for certain workforces and obtaining cybersecurity risk insurance, as well as recommending that sensitive data be stored in multiple geographically isolated data centers to provide an added layer of redundancy.

Troutman requested that its proposals to tighten NYISO’s security and information-sharing procedures be approved quickly but some stakeholders were skeptical about the proposed implementation timeline and whether the CEII protections were more restrictive than protective.

Doreen Saia, an attorney with Greenberg Traurig, said Troutman was unrealistic to expect its proposals could be approved before the end of the year, given the number of meetings and the upcoming holiday season, as well as considering the breadth of the proposal.

Stu Caplan, partner at Troutman Pepper, asked what a realistic timeline would be. Saia responded that her firm would need at least a month or more to review the requirements, but that multinational organizations likely would need even more time to comply with the requirements, particularly those related to geographic data storage.

Glenn Haake, vice president of regulatory affairs at Invenergy, concurred with Saia, noting how multinational companies might struggle with these requirements, particularly if the rules vary by country of origin.

O’Konski sought to mollify these concerns by noting how Troutman’s proposals are intended to create a single set of CEII standards applicable for everyone.

Kevin Lang, partner at Couch White, in reference to expanding the list of personnel required to obtain CEII clearance, said Troutman needs to consider that not every NYISO market participant has the same level of resources as transmission owners and to ensure its requirements are not preventing smaller businesses from accessing the ISO’s data.

There was a consensus on the need for enhanced CEII protections and no one opposed the measures outright, but stakeholders wanted to guarantee a balance between security and accessibility.

Troutman will return with a more detailed proposal and requested feedback be sent to either Caplan or O’Konski by Sept. 28.

System & Resource Outlook

NYISO updated stakeholders that the base case lockdown date for the biennial System & Resource Outlook report has been set for Oct. 15.

The base case serves as the foundational set of initial conditions, scenarios and assumptions used in the Outlook’s modeling.

The 20-year forecasting report examines how New York’s transmission system develops, performs, and responds to the state’s aggressive climate and energy legislation. (See “System & Resource Outlook,” NYISO Previews New York City Transmission Needs Assessment.)

FERC Directs J.P. Morgan to Declare Affiliations of Two Holding Firms

FERC issued an order Thursday finding J.P. Morgan Investment Management qualified as an affiliate of Mankato Companies and IIF US Holding 2, through which it is tied to other firms, including El Paso Electric.

The order came after a Section 206 briefing process FERC started after consumer group Public Citizen questioned the investment bank’s ties to firms it said were not appropriately disclosed.

Public Citizen said the investment bank effectively controlled IIF, through Mankato and other subsidiaries. The two legal entities share employees and effectively let the investment bank make decisions on running IIF.

FERC found the relationship between J.P. Morgan Investment, IIF and Mankato was such that there is liable “to be an absence of arm’s length bargaining in transactions between them,” so it’s appropriate to consider them affiliates for the protection of investors and consumers.

The two firms share operations under an Investment Advisory Agreement and a Partnership Agreement, which delegate J.P. Morgan Investment broad duties to run IIF. A J.P. Morgan Investment employee sits on the board of directors of Onward Energy as a representative of IIF.

“We emphasize that in the market-based rate context, an assessment of affiliation is necessary to understand the relationships between entities to ensure that rates are just and reasonable, to protect against the exercise of market power and to protect customers from affiliate abuse that can result from affiliate transactions, regardless of the presence of fiduciary duties,” FERC said.

Employees of J.P. Morgan and J.P. Morgan Investment signed the partnership agreement and investor advisory agreement for both firms. That at least shows J.P. Morgan was empowered to execute documents that bind IIF into agreements, including agreements with the investment bank itself.

The investment agreement between the firms authorizes J.P. Morgan as investment adviser to “have full authority to undertake and perform any and all acts deemed necessary or appropriate by it in connection with the rights, powers and duties delegated to it.” The partnership agreement explains J.P. Morgan has the power to manage IIF’s business and affairs, to make business decisions, to act on its behalf and take any actions it deems appropriate.

“These rights and powers allow J.P. Morgan Investment to make virtually every major decision on behalf of IIF US Holding 2,” FERC said.

The commission directed Mankato to file a change in status and update its asset appendices to reflect J.P. Morgan Investment as an affiliate. The firm’s market power analysis will need to be updated to reflect the affiliation.

The order drew a concurrence from Commissioner James Danly, and a response to that from Chairman Willie Phillips.

Danly wrote to make clear that while he supports the outcome of the order, he takes issue with the majority’s reasoning. He argued concurrences should be the same as a dissent as a result.

“I disagree with the means by which we arrive at that conclusion,” Danly said. “I do not believe that we need to disclose privileged information to the extent we do to justify our conclusion. We could and should have been more measured.”

Phillips said concurrences amount to the opposite of a dissent and Danly cited no precedent supporting his view that concurrences should be treated that way on review by the courts.

“Commissioner Danly is, as ever, entitled to his opinion,” Phillips said. “I write separately to stress that I do not share that opinion and to underscore that Commissioner Danly is not stating the commission’s view on this issue. As Commissioner Danly correctly notes in his concurrence, it is our agency’s ‘institutional decisions — none other — that bear legal significance.’”

ISO-NE Must Include Pumped Hydro in Inventoried Energy Program, FERC Rules

ISO-NE must include pumped storage resources in its Inventoried Energy Program (IEP), FERC ruled on Thursday, siding with Brookfield Renewable Trading and Marketing in the company’s complaint against the RTO (EL23-89).

The IEP is intended to compensate resources for storing extra fuel they otherwise would not procure during periods of winter reliability risk. (See FERC Approves Updates to ISO-NE Inventoried Energy Program.) The D.C. Circuit Court of Appeals ruled in 2022 the IEP cannot extend to nuclear, coal, biomass and hydroelectric resources because the program would not result in a change of their fuel storage behaviors.

Following the D.C. Circuit ruling, ISO-NE submitted — and FERC approved — a version of the IEP which excluded the specified resources, including pumped storage. Brookfield Renewable, which operates a 633-MW pumped hydro storage facility in western Massachusetts, filed a complaint over the exclusion of the resource type in August.

In FERC’s ruling on Thursday, the commission said the D.C. Circuit ruling does not preclude the inclusion of pumped storage because these facilities fall under the category of electric storage facilities, which are allowed to receive payments in the IEP.

“As the ISO-NE tariff currently permits battery storage electric storage facilities to be eligible to participate in the Inventoried Energy Program, it is unduly discriminatory to prohibit pumped storage electric storage facilities, which similarly store energy to later inject the energy into the system, from being eligible to participate in the Inventoried Energy Program and receive those payments,” the commission wrote.

FERC wrote that IEP payments likely would incentivize pumped storage facilities to alter their behavior and boost reliability in the region.

“Allowing pumped storage electric storage facilities to be eligible to participate in the Inventoried Energy Program, similar to other electric storage facilities, can alter their incentives and thus their behavior by providing an incremental financial incentive to store energy,” the commission wrote in the Sept. 21 ruling.

FirstLight Power and the New England Power Generators Association both submitted comments in August supporting Brookfield’s complaint, while a group of consumer-owned power companies opposed it.

The consumer-owned power companies argued the complaint was attempting to relitigate previous findings and that including pumped storage in the IEP would not result in more stored energy.

“Brookfield’s complaint fails to show that any system-wide incremental energy production would result from extending the IEP’s incentive compensation mechanism to pumped storage hydro facilities,” the group wrote.

In its complaint, Brookfield argued pumped storage operates in the same way as any other type of electric storage.

“The fact that one ESF [electric storage facility] may use pumped storage technology and another ESF may use a chemical battery is irrelevant because they both are able to provide the identical winter reliability service through the IEP,” Brookfield wrote. “Because all ESF technologies operate under the same economic principles, the same incentive exists for all ESFs to provide reliability service through the IEP.”

ISO-NE told FERC it did not oppose the inclusion of pumped storage in the IEP but said it believed the D.C. Circuit ruling prevented their inclusion in the program.

“The D.C. Circuit’s Belmont decision did not differentiate between pondage and pumped hydroelectric resources, but instead simply indicated that ‘hydroelectric’ resources must be excluded from the IEP,” ISO-NE wrote. “The Belmont court did not provide any exception for pumped hydroelectric resources to participate in the IEP as ESFs.”

ISO-NE had said it needed a FERC order by Sept. 22 to include pumped storage in the IEP for the upcoming winter.

NJ’s Push Toward Clean Cars Rule Sparks Vigorous Debate

New Jersey’s planned adoption of California’s Advanced Clean Car II (ACC II) rules stirred a heated exchange Thursday as business groups argued the state is far from ready for a sudden surge in electric vehicle use and environmentalists argued climate change threats demand the rules be in place by 2024.

Groups representing car dealers, gas station convenience stores, the petroleum industry, businesses and other sectors at an online public hearing on the rules organized by the New Jersey Department of Environmental Protection said mandating EV sales would disenfranchise numerous low-income consumers who already struggle to buy a car.

The three-hour online hearing, the only one scheduled, drew more than 40 speakers. It came as ACC II supporters are urging the administration of Gov. Phil Murphy (D) to have the rules in place by the end of the year so they can impact the 2027 model year. The eight-week-long public comment period will end Oct. 20. (See NJ Sets Advanced Clean Cars II Proposal in Motion.)

ACC II calls for a steady increase in EV sales as a portion of all new light-duty vehicle sales, until they account for 100% in 2035. But, business groups argue, that mandate would push up the price of used cars as consumers looked for a cheaper alternative to the higher-priced clean energy-fueled vehicle, framing the rules as a big government intervention in what should be a decision by the market.

“New Jersey and all the other ACC II states will be a 100% EV sales market when consumers want to buy only EVs, not when government mandates it,” said Jim Appleton, president of the New Jersey Coalition of Automotive Retailers (NJCAR).  “Frankly, we believe this plan will frustrate and cause a consumer backlash that will slow our roll to an EV future, not accelerate.”

He argued that if consumers face a mandate for sales increases when they find the prices high, or access to the charging infrastructure unreliable, they will simply “hold on to their older cars longer or opt into the used car market which is not regulated by ACC II.”

Other opponents argued the state’s grid is not ready to provide the amount of electricity needed to serve hundreds of thousands — perhaps millions — of EVs. And they questioned the impact on carbon reduction, saying much of the electricity still might be generated with natural gas.

‘Shackles of Saudi Arabia’

Supporters of the rules — including EV manufacturers, health care professionals and some businesses — made up the majority of speakers at the hearing, however. They argued that recent extreme weather events — including the hottest summer on record — show the state needs to rapidly stoke EV adoption.

Pam Frank, CEO of ChargeEVC, a nonprofit coalition that promotes EV growth, said that with 123,000 EVs on the road in June, the state still is far from its goal of 330,000 EVs by 2025. A draft Strategic Climate Action Plan released by the DEP last week said the state would need 4.5 million light-duty EVs by 2035 to meet the state’s clean energy goals, accounting for 73% of all light-duty vehicles.

“Allowing the markets to set policy for the kinds of cars we drive will just not get us where we need to be as quickly as possible,” Frank said. “This is not a ban on [internal combustion] engine vehicles,” she said. She added most New Jerseyans buy used vehicles and that market would continue regardless of the new rules.

Supporters of ACC II argued EV prices already are declining and consumers would benefit because powering electric vehicles is cheaper than running on fossil fuel.

“Let me state emphatically that there’s nothing worse for New Jersey’s businesses than high oil prices,” said Sean Mohen, executive director of Tri-County Sustainability Alliance, which promotes sustainability in South Jersey. He argued that oil production cuts by Russia and Saudi Arabia had pushed up gas prices to their highest level this year, and demonstrated the need to focus more on electricity.

“It’s time for America and New Jersey to throw off the shackles of Saudi Arabia for both climate and business reasons,” he said.

Accounting for Health Costs

As adopted by California last August, ACC II requires car manufacturers to provide an increasing percentage of zero-emission vehicles (ZEVs) for sale each year. It defines zero-emission vehicles as battery-electric, hydrogen fuel cell or plug-in hybrid.

The regulation starts with a 35% ZEV sales requirement for model year 2026, increasing to 68% in 2030 and reaching 100% in 2035. ACC II also includes increasingly stringent standards to reduce tailpipe emissions of gasoline-powered cars and heavier passenger trucks.

State officials announced the process for adopting ACC II in February, setting off a vigorous campaign between supporters and opponents over the rules’ merits. A coalition of 100 businesses two weeks ago submitted a letter to state Senate President Nicholas Scutari and Assembly Speaker Craig Coughlin, both Democrats, urging them to reject the rules and instead take legislative action on the issue. (See NJ Businesses Demand Halt to EV Sales Promotion Rules.)

If New Jersey approves the rules, it would be the ninth state to do so. Maryland last week joined Massachusetts, New York, Oregon, Vermont, Virginia and Washington in adopting the California rules. (See Maryland Moves Ahead with Advanced Clean Car and Truck Rules.)

Richard Lawton, executive director of the New Jersey Sustainable Business Council, which represents companies seeking a sustainable economy, said the state should be clear about the motives of some opponents to ACC II.

“EV technology represents a competitive threat to industries and companies who have a vested interest in maintaining the monopoly power of fossil fuels, and [they] are using their economic and political power to raise as many barriers to entry as possible,” he said.

“This is perfectly rational for them, but not for the rest of us,” he said. “Top economists have called climate change the largest market failure in history. So relying on market forces alone to address this market failure would be self-defeating, and frankly, naive.”

Rural Difficulties

Several supporters focused on the health benefits of EVs, saying ACC II especially would improve the quality of life for minority communities that have long suffered the effects of vehicle pollution in urban areas and neighborhoods next to highways.

“Air pollution resulting from transportation in New Jersey is first and foremost a health issue, and discussions of costs that don’t include health costs is imbalanced,” said Dr. Elizabeth Cerceo, chair of health and public policy for the American College of Physicians New Jersey. “When this is factored in, the social and mortality cost of carbon, it outweighs the cost of EV transition. The supposition that the market should dictate the decision ignores the lives lost and the illness caused by fossil fuel pollution.”

But Mary Jo Foley, speaker for the Rural and Agriculture Council of America, argued that adopting ACC II would unfairly and excessively impact the nearly 850,000 residents of the state who live in rural areas.

“New Jersey’s rural and agricultural communities will be hardest hit by this proposal,” she said. “Internal combustion engine vehicles are a necessary part of everyday life for rural Americans, where it’s not an easy task to find an electric vehicle charging station.”

She added that “there will be massive increased demands in the New Jersey power grid, which also likely means higher prices for New Jersey electricity consumers who already pay some of the highest rates in the country.”

‘Challenging’ Grid Conditions Led to CAISO’s Summer Emergency Alerts

CAISO’s issuance of energy emergency watches and alerts on three days in July came under conditions that mirrored those during California’s September 2022 heatwave, officials said.

Several “challenging evenings of grid operations” led the ISO to issue a Stage 1 energy emergency alert (EEA 1) on July 20, followed by EEA watches on July 25 and 26, CAISO CEO Elliot Mainzer told the Board of Governors on Thursday.

The period was marked by high demand from a record-setting heat wave in the Southwest, Mainzer said, while demand was “high but not excessive” in California and hydro conditions in the Pacific Northwest were below average.

In the Southwest, record-breaking temperatures included an average high in Phoenix of 114.7 degrees for the month of July, compared to the previous record of 109.8 degrees in July 2020.

“In many ways, conditions were the mirror image of what we saw last September when California was on the edge with a historic heat wave, and other regions were able to supply us with large quantities of power to help maintain reliability,” Mainzer said in a report to the board.

So far, the three alerts are the only times CAISO triggered the emergency alert system this year, Mainzer said. No Flex Alerts — in which consumers are asked to voluntarily conserve energy — have been issued in 2023.

In addition to Mainzer’s report to the board, CAISO also released last week a summer market performance report for July that goes into more detail on the EEA events. A Sept. 27 meeting has been scheduled to discuss the report.

July 20: EEA 1

Energy emergency alerts range from EEA 1, which includes calls for conservation measures and demand response, to EEA 3, in which rotating blackouts may be ordered. An EEA watch is a preliminary step before CAISO declares an alert.

When an energy emergency alert or watch is issued, CAISO has access to additional resources, such as the emergency load reduction program (ELRP), in which electricity customers are paid to voluntarily reduce their demand, and the state’s Strategic Reliability Reserve.

CAISO issued an EEA 1 at 7:30 p.m. on July 20 in response to “rapidly evolving grid conditions observed during real-time operations,” according to the monthly performance report. The July 20 conditions came up relatively unexpectedly, in contrast to grid events in 2020 and 2022 that were projected far in advance, the report said.

One and two days ahead, the market seemed able to meet the projected demand for July 20, although with thinning capacity margins.

But as the system approached net load peak on July 20, “the anticipated supply did not fully materialize,” the report said.

CAISO said reasons for the decreased supply included resource outages and derates; fewer imports due to potential fire impacts; and resources not dispatched due to congestion.

At the same time, demand was high from the desert Southwest, which experienced record-breaking high temperatures this summer. As a result, net imports were reduced during the net load peak.

Another issue was that a display of resource availability overestimated the amount of resource dispatch capability available — mostly due to storage resources that were providing multiple services, CAISO said.

As a result of the EEA 1, CAISO deployed resources from the ELRP. Normal operations resumed around 8:30 p.m.

July 25 and 26: EEA Watch

Factors similar to those that occurred on July 20 led CAISO to issue an EEA watch on July 25, effective at 7:30 p.m.

The ISO said it was seeing high external demand, wildfire threats to transmission, and the loss of about 2,000 MW of California resources “due to outages between the day-ahead and real-time markets.”

During peak hours, congestion on the Path 26 transmission lines made it difficult to send supply from the northern part of the system to Southern California, where it was still hot.

Another EEA watch was issued for July 26, from 6 to 10 p.m.

The report also discussed the flexible ramping product used by the real-time market. The EEA 1 on July 20 was sparked by a ramping shortfall as solar resources went offline in the evening hours.

The ramping product doesn’t procure capacity in response to unexpected outages or loss of imports, and so it had limited success addressing emerging uncertainty issues during the July events, CAISO said.

September 2022 Heat Wave

This year’s highest peak demand so far was 43,545 MW on July 25 at 6:27 p.m., well below the record peak of 52,061 MW on Sept. 6, 2022, during last year’s California heat wave. CAISO declared an EEA 3 that day but rotating blackouts were avoided after the governor’s Office of Emergency Services sent out a text alert at 5:45 p.m. urging consumers to conserve electricity.

Within 20 minutes, demand plunged by 2,385 MW and blackouts were averted. (See CAISO Reports on Summer Heat Wave Performance.)

Overall, operational conditions this summer have been “significantly less strained” compared to last year, CAISO said.

The state has been better positioned in terms of resource adequacy because of a record snowpack and strong hydro production, along with the addition of significant amounts of generating and storage resources.

Mainzer said August was another month with “a set of interesting conditions West-wide.” CAISO expects to release a market performance report for August next month.

FERC Approves PJM Cost Recovery for NERC Penalty

FERC ruled last week that PJM can go to its customers to recover a $140,000 penalty leveled against the RTO this year by ReliabilityFirst, with Commissioner James Danly “reluctantly” concurring but calling for an investigation into PJM’s reliability violations and “manifest failures” to ensure reasonable electricity rates (ER23-2327).

PJM agreed to the penalty as part of a settlement with RF approved by FERC in April over several violations of NERC reliability standards — some at the Quad Cities and Dresden nuclear plants in Illinois, and others stemming from coordination issues at transmission facilities owned by FirstEnergy Utilities (NP23-13). (See PJM Hit With $140K Penalty for NERC Violations.)

According to a guidance order issued by FERC in 2008, RTOs and ISOs may “request recovery of penalty costs by spreading those costs among their members and/or consumers on a case-by-case basis.” Such requests must meet several criteria to be eligible for commission approval, including:

    • Whether the RTO or ISO involved had a compliance program in place.
    • Whether the violations were due to intent or gross neglect.
    • Whether management was involved in the violations.
    • The ability of the organization to pay the penalty.
    • The fairness of the RTO’s or ISO’s proposed assessment mechanism.

On June 30, PJM requested that FERC approve the recovery of the $140,000 RF penalty from its customers. The RTO explained that while it previously would have paid penalties from its administrative cost recovery rates, a change to its tariff in January 2022 meant the rates would no longer be “sufficient to absorb penalty costs.”

PJM claimed its proposed recovery was consistent with the criteria in FERC’s 2008 guidance order, noting that it possesses “a robust internal compliance program,” that all the violations were inadvertent and no harm to the grid resulted, and that management was not involved in the violations. The RTO said its proposal would allow “a broad allocation of the costs,” with a low impact on individual consumers; according to PJM, if recovered in a single month, the resulting additional cost to consumers would be around a fifth of a cent per MWh.

Public Citizen objected to PJM’s request, stating that putting the cost of the penalty on consumers would be “unjust and unreasonable. Instead of recovering the cost from consumers, the consumer advocacy group suggested that “PJM executives and PJM’s Board of Managers should be financially responsible for the penalties.”

This approach would be consistent with a FERC ruling last year against ISO-NE over construction delays at a Boston-area generating plant, Public Citizen said. In that case, ISO-NE agreed to a $500,000 civil penalty that was paid for through a reduction in executive compensation. (See FERC Investigation Faults ISO-NE in Capacity Market Fraud.)

PJM in turn pushed back on this suggestion, pointing out that the 2008 order on cost recovery was not applicable to the ISO-NE violation, which did not concern recovery of a NERC penalty. Furthermore, PJM said, FERC did not require ISO-NE to pay its penalty from executive compensation; the ISO made that decision on its own. The RTO reiterated that its proposed recovery mechanism is valid under the 2008 order and suggested Public Citizen has a problem with the order itself, not with PJM’s use of it.

FERC sided with PJM on the applicability of its 2008 order and said commissioners were “not persuaded” by the arguments of Public Citizen. The commission said that because PJM had “adequately addressed the factors identified by the guidance order,” it would grant the RTO’s request for cost recovery, effective Aug. 30.

But commissioners’ reactions to the decision were mixed, as Danly’s concurrence demonstrated. While the commissioner agreed PJM had “met its relatively light burden” of proof regarding its ability to recover costs, he argued in his filing that not only does the RTO have a history of “undercutting or dismantling core market design principles essential for just and reasonable rates,” the case makes clear that “PJM also is not very good at reliability.”

“I would treat PJM like the public utility that it is and … investigate PJM’s manifest failures to ensure or at least advocate for just and reasonable rates — and now to also investigate whether PJM is complying with existing reliability rules,” Danly said. “The commission should not hesitate to enquire whether a public utility serving as [an RTO] should continue in this critical role when rates and reliability failures suggest it is not doing very well.”

Danly suggested that the commission has authority to conduct such an investigation under Section 206 of the Federal Power Act. Although FERC has not taken this action on its own, Danly pointed out that “any entity with standing” could file a case, and wondered if this would “have more of an effect … than a $140,000 penalty that we pass through to ratepayers.”

MISO Charting Course on Stimulating Generating Attributes

MISO last week said it continues research to gauge the quantity of generating attributes it might prescribe for its fleet.

MISO has defined six system reliability attributes as necessary, including availability, rapid start times, the ability to deliver long-duration energy at a high output and providing voltage stability, ramp-up capability and fuel supply certainty. (See MISO Considers Resource Attributes as Thermal Output Falls.) The RTO is studying what role it can play in maintaining those increasingly scarce reliability attributes from generation in the long term.

The RTO will share what changes it thinks might be necessary in an action plan it plans to publish at the end of the year.

“A growing body of experiences in MISO and across the industry has led MISO to focus on ensuring reliability system attributes are understood and maintained,” Director of Policy Studies Jordan Bakke said during a Sept. 21 stakeholder workshop.

Bakke said MISO can learn and borrow solutions from smaller countries and how they’ve approached ensuring attributes. He said EirGrid in Ireland has similar challenges with its transitioning resource mix.

MISO’s Patrick Dalton said the strength of MISO’s system can be thought of as a trampoline that’s slowly losing spring because intermittent resources aren’t replacing the characteristics of baseload generation.

Bakke said less predictable weather paired with less predictable generation means MISO must focus on supplying energy for the worst week in every season instead of just the worst peak load in the summer.

Michael Milligan, a consultant to GridLab, asked how MISO will calculate the quantity of attributes necessary while tracking the rate that MISO is losing them.

“That is our intent, and that’s inherently difficult to do as we’ve learned over the last several months,” Bakke said. However, he said landing on specific amounts of attributes is “core” to what MISO is trying to accomplish.

Minnesota Public Utilities Commission staff member Hwikwon Ham said states need in-depth information as early as possible on how MISO plans to measure needed attributes so commissions can integrate them in state-level resource planning.

WEC Energy Group’s Chris Plante pointed out that MISO already has incorporated and is planning major resource adequacy changes, including capacity accreditation, a seasonal capacity auction design and sloped demand curve in the auction. He said those changes are driving a “fundamental change” in how resource planners approach generation planning. He said planners have reverted to an older style of resource planning, where they ensure they own energy adequacy and rely less on the MISO markets.

“I think it’s important that we keep that in mind that the shift is already occurring,” he said.

Plante also said new planning might mean MISO’s middle-of-the-road transmission planning future, which it’s using to analyze attributes, might be outdated in light of the new, more independent style of resource planning.

IMM Skeptical

MISO Independent Market Monitor David Patton repeated his reservations with MISO’s accreditation work at a Gulf Coast Power Association virtual forum Sept. 15.

“I don’t oppose the work in general, but I do oppose the notion of singling out specific attributes and identifying a megawatt quantity that’s needed because it points to the wrong solution, which is we should create products related to these attributes,” Patton said.

Instead, MISO should put more emphasis on applying marginal capacity accreditation with sound modeling behind it, Patton said. He said MISO will naturally entice units with reliability attributes if it portions out capacity credit based on how nimble and stable generators are.

“Units with good attributes will get high accreditation, and units with attributes that don’t help you much from a reliability standpoint will get low accreditation levels,” Patton said.

MISO has planned another attributes discussion during a dedicated Oct. 31 workshop, then again at the Nov. 8 Resource Adequacy Subcommittee.

MISO Relaxes Proposal on Stricter Queue Ruleset

MISO convened a special meeting last week on its plan to downsize the number of projects allowed in its generator interconnection queue.

Since last month, the RTO has pared down proposed fees for projects to enter the queue and penalties assessed upon dropping out.

MISO intends to place an annual megawatt limit on project proposals, collect higher entry fees, enact escalating penalty charges and require developers to verify they have obtained land. RTO planners have said the plan will ensure that only the most prepared projects will have a spot in the queue and reduce speculative projects that drop out and gum up network upgrade studies. (See MISO Sticks with MW Caps, Higher Fees to Pare Down Queue RequestsMISO Aims for Manageable Interconnection Queue.)

Now, the grid operator has cut back its first milestone fee paid to enter the queue from a proposed $10,000/MW to $8,000/MW. The fee currently stands at $4,000/MW; MISO first proposed to increase the fee to $12,000/MW in summer.

“We don’t plan to lower it any more. We think 8K is on the low end,” MISO’s Andy Witmeier told stakeholders.

Witmeier also said MISO has lowered its automatic penalty schedule so it can hold onto 10% instead of 25% of the first milestone fee at the queue’s first decision point and 35% instead of 50% by the second decision point.

The remainder of MISO’s automatic penalty structure proposal remains unchanged for the final two penalty points. A developer will still risk 75% by the time their project reaches the third and final phase of the queue and, finally, 100% if they drop out during the negotiation stage of the generator interconnection agreement.

Witmeier said MISO supports interconnection customers deciding to withdraw their projects as soon as they know they’re infeasible rather than lingering in the queue.

“I think we’re honing in on a really good proposal that we can bring to FERC in October,” Witmeier said.

MISO’s interconnection queue now stands at more than 240 GW across more than 1,400 projects.

MISO has a goal to file before the end of October, so its proposal is registered with FERC before the commission’s Order 2023 takes effect Nov. 5. Although MISO considers its proposal separate from Order 2023, the grid operator isn’t certain how the final rule will interact with the tightening of the MISO queue.

However, MISO still is working out how it will calculate its yearly megawatt cap on interconnection requests.

“We all agree we have a math problem here” in terms of how many projects MISO can realistically study, Witmeier said.

He added that MISO’s cap will include a “safety valve” feature that will allow developers to exceed the cap when projects are intended for load serving obligations, have a power purchase agreement, are an approved generator replacement facility or when projects simply are requesting to convert their unguaranteed level of interconnection service to firm service.

Consulting firm Charles Rivers Associates (CRA) reached similar solutions to help control MISO’s queue stampede.

MISO enlisted the help of CRA to review independently how MISO can best cut down on both its queue size and rate of withdrawals.

CRA concluded MISO should raise its first milestone fee from $4,000/MW to anywhere from $10,000 to $14,000/MW, install queue entry caps and enact an escalating fixed penalty schedule and a minimum penalty at every stage for withdrawing projects.

“After years of remaining relatively stable, the MISO queue has inflated to unmanageable levels in recent years,” CRA’s Margarita Patria said.

Patria said CRA’s recommendations strive to incentivize customers entering the MISO queue only after “really careful consideration.”

Patria said there “should be some consequences” for withdrawing projects because it’s a reality that withdrawing projects negatively impact other projects, even though the dollar amount is difficult to quantify.

Witmeier said MISO agrees its “pre-queue activity” needs to improve, as stakeholders have suggested. He said MISO plans to improve its existing point of interconnection tool to consider active interconnection requests and give developers a better idea of the feasibility of their projects.

He also said MISO plans to hold more informative scoping discussions with developers, use advanced analytics to share data on projects progressing in and exiting the queue alike and is considering using interactive AI chat bots to answer developers’ questions about MISO’s queue rules.
