NERC Troubled by Responses to IBR Alert

Many generator owners (GOs) are not following NERC‘s recommendations for improving the performance of inverter-based resources (IBRs), and new reliability standard projects and other regulatory actions may be needed to enhance these generators’ reliability, according to the findings of a Level 2 alert the ERO released Nov. 30. 

NERC issued the alert in March, providing a series of recommendations that GOs were “strongly encouraged to adopt.” (See NERC Issues Level 2 Alert on IBR Issues.) Recipients were required to respond to a series of questions about their grid-connected solar facilities (if any). While the topic of the alert was solar subject to NERC standards, the ERO said in Thursday’s report the recommendations may be applicable to other IBRs including wind and battery energy storage systems. 

Entities initially were required to submit their responses to the alert by June 30, but NERC said it had received only 15 submissions by the due date, which the ERO called an “unprecedented and unexpected low response rate.” As a result, the deadline was extended to July 31. By the end of the extension, NERC received 1,149 responses, for a response rate of about 97%.  

A total of 217 entities reported owning one or more grid-connected solar facilities. The greatest number of positive responses, 85, came from entities in WECC. SERC Reliability followed with 59, and the Texas Reliability Entity came next with 45. Also, 18 entities in ReliabilityFirst reported having applicable resources, followed by eight in the Midwest Reliability Organization and just two in the Northeast Power Coordinating Council.  

Difficulties Obtaining Needed Data

All but three utilities with grid-connected solar resources submitted responses to the alert’s questions by the extended deadline, despite “anecdotal comments [that] indicated that the data was difficult to obtain,” NERC said. GOs reported needing “significant assistance from OEMs [original equipment manufacturers] or consultants,” but OEMs and consultants themselves said they also had problems getting needed information from GOs and each other. 

The quality of data submitted was questionable even though most worksheets were technically complete, the report said, with analysis of the responses showing “significant and numerous instances of misunderstanding … the information requested.” In one case, a GO said its inverter manufacturers had not “experienced instances of inadvertent tripping at other facilities” even though its equipment had been “documented to be involved in past major disturbances.” 

NERC said it developed the worksheet questions based on input from industry groups and experience from multiple IBR events analyzed by the ERO Enterprise, under the assumption that GOs “would have the requested information available to submit with relative ease.” That such issues exist within the submissions casts “doubt on the accuracy and quality of the submitted modeling data used in reliability studies,” which also would come from GOs, the ERO added.  

NERC’s analysis of the data indicated widespread deviations from the ERO’s guidance. For example, about 2,260 grid-connected solar facilities have voltage and frequency protection settings within the “no-trip zone” defined by NERC’s reliability standard PRC-024-3 (Frequency and voltage protection settings for generating resources). While the standard allows for protection settings to border and enter the no-trip zone in some circumstances, NERC said the facilities in question are “at an elevated risk of tripping during [grid] disturbances.” 

The ERO also found that less than a third of solar facilities’ protection settings were based on the maximum capability of the equipment, indicating that “there is significant underused ride-through capability across the” electric grid and raising concerns about the availability of reliability services as traditional generation sources are retired. Additionally, about 27% of the solar fleet by MW is not configured with NERC’s recommended ride-through settings, though the report acknowledged that many of these facilities may be older and not capable of being modified. 

New Standard Actions Recommended

NERC concluded many GOs and generator operators are providing “only the minimum [performance] as explicitly stated in FERC orders, regional requirements, and NERC reliability standards,” which can put the grid at risk of losing significant amounts of resources and essential reliability services. 

One reason for the shortcomings identified by the ERO is the lack of uniform performance requirements for solar facilities. NERC said its Inverter-Based Resource Performance Subcommittee (IRPS) is developing a standard authorization request (SAR) to update FAC-001-4 (Facility interconnection requirements) and standardize performance requirements across North America. Two other standard projects — Project 2020-02 (Modifications to PRC-024) and Project 2023-02 (Performance of IBRs) — are expected to help with the performance deficiencies as well. 

NERC also faulted “systemic deficiencies in the availability and understanding of facility information,” and recommended the IRPS draft a new SAR to introduce commissioning requirements for GOs of IBR facilities. The ERO further said its concerns about the quality of modeling data should be addressed as soon as possible. 

NERC said it will issue another Level 2 alert next year to gather modeling and study information from GOs and transmission providers, and to “share recommended practices regarding modeling and study enhancements.” A Level 3 alert will follow “in the first half of 2024” with essential actions for GOs to address high-risk IBR issues. 

FERC Upholds Ruling on ISO-NE’s IEP Payments

FERC has upheld its ruling on a series of updates to ISO-NE’s Inventoried Energy Program (IEP) which could result in larger payments for generators to keep stored fuel on-site as a grid reliability backstop (ER23-1588).

The commission initially approved ISO-NE’s changes in early August, despite protests from consumer advocates and environmental organizations. (See FERC Approves Updates to ISO-NE Inventoried Energy Program.)

The changes shift the IEP from fixed payment rate format to indexed rates and are intended to “align the program with current market conditions,” according to ISO-NE. The IEP compensates generators for storing up to three days’ worth of stored fuel and covers the winters of 2023-24 and 2024-25.

Climate organizations argue the changes amount to an unnecessary subsidy for fossil fuel generation. The Sierra Club, Union of Concerned Scientists and Conservation Law Foundation filed for a rehearing in early September.

“The order approves significantly increased incentive payments to oil and gas generators with no assurance that these incentives will change those generators’ behavior in ways that improve reliability,” the organizations wrote in their request. “The commission failed to assess whether the benefits to consumers justified the costs.”

FERC denied the request by default due to the lack of timely action in October. In the Nov. 30 order, the commission upheld its ruling while responding to the arguments of the rehearing request.

“The proposed tariff revisions represent a just and reasonable means of updating the program payment rates to ensure that the Inventoried Energy Program provides appropriate incentives and compensation for market participants to participate in the program,” the commission wrote.

FERC also disagreed with the climate groups about how the IEP will affect generators’ behavior, concluding “ISO-NE’s proposed indexed rates are expected to change market participants’ behavior in the manner intended.”

In the rehearing request, the climate organizations argued most relevant generators already are required by their capacity supply obligations to be available to produce energy, making additional payments from the IEP unnecessary.

FERC disagreed, writing that “the capacity supply obligation does not require the same behavior that the Inventoried Energy Program is designed to incent.”

While the climate groups argued recent ISO-NE studies indicate that “even in a severe winter, there is negligible reliability risk, in part due to increased deployment of wind and solar resources,” FERC said ISO-NE’s winter reliability analyses cited by the environmental groups “actually underscore the important role of the Inventoried Energy Program in providing winter reliability in New England.”

“The winter analyses rely on the assumption that the Inventoried Energy Program will ‘operate as intended’ and that the Inventoried Energy Program will fulfill its purpose of enhancing reliability,” FERC wrote.

Casey Roberts, senior attorney at Sierra Club, wrote in a statement that the organization is disappointed with FERC’s ruling.

“Rather than raising costs for ratepayers across the region to pay polluting oil and gas generators, ISO-NE should instead focus its efforts on building a reliable, lower-cost electric system by bringing more wind and solar online and ramping up energy storage,” Roberts said.

Roberts added that the Sierra Club “will continue to review FERC’s order as we consider our next steps moving forward.”

Senate Energy Committee Examines State of Advanced Nuclear Reactors

The Senate Energy and Natural Resources Committee on Thursday looked into the state of advanced nuclear reactors just weeks after NuScale Power and Utah Associated Municipal Power Systems terminated a once promising pilot project. (See Pioneering NuScale Small Modular Reactor Project Canceled.) 

Both the Infrastructure Investment and Jobs Act and the Inflation Reduction Act gave billions of dollars to the sector for demonstration projects and commercialization incentives, said committee Chair Joe Manchin (D-W.Va.). 

“Despite all of the federal and private sector support, we’re witnessing struggles and hesitancy in getting advanced nuclear projects off the ground,” Manchin said. “There are large design, cost and regulatory uncertainties associated with first-of-a-kind nuclear technology — which is why we’ve now created numerous federal programs to help reduce these risks. But someone will need to go first, and unfortunately many of the utilities I’ve spoken with won’t get in the game until others have done it first.” 

The recently canceled Carbon Free Power Project was going to be constructed at the Idaho National Laboratory by NuScale, featuring 60- to 77-MW modules that could be scaled up as the municipal power agency’s needs grew, said lab Director John Wagner. 

The project got $771 million in funding from the federal government that taxpayers will not get back, as it was picked for the grant in a noncompetitive process, unlike other advanced nuclear pilots by TerraPower and X-energy, Manchin said. 

“I can’t speak to the procurement process, and so on and so forth,” Wagner said. “I can speak to … a lot was accomplished with that project, despite the fact that it was ultimately decided to be terminated. A design certification for an advanced small light water reactor was accomplished; experience with the licensing process; experience with developing the supply chain.” 

While the project offered a chance to test out the regulatory process, in his written testimony Wagner said the industry has to end the “era of constructing paper reactors.” 

“The Carbon Free Power Project was suspended because of economics,” Wagner wrote. “A lack of subscriptions was directly related to the cost issues surrounding deployment of first-of-its-kind technologies.” 

The Department of Energy’s “commercial liftoff” report for advanced nuclear gave several recommendations to enable a “committed orderbook,” said Wagner: cost overrun insurance, tiered grant financial assistance, government ownership, and government-enabled off-take certainty. (See DOE Reports Highlight 3 Technologies to Decarbonize US Economy.) 

Utility executives have indicated they do not want to go first on developing new nuclear technology, especially given Southern Co.’s experience with the Vogtle plant and its massive cost overruns, said Manchin. He asked the witnesses how to overcome that resistance. 

The next reactors will benefit from the investment and production tax credits from recent legislation, but that is not enough to get the first reactor built, said Jeffrey Merrifield, a former Nuclear Regulatory Commissioner and chair of the U.S. Nuclear Industry Council’s Advanced Nuclear Working Group. 

“That’s where I think there needs to be a backstop program,” Merrifield said. “So that if there are timing delays [or] cost overruns, there can be a sharing of that cost and not burden that single company, whether it’s a utility or an industrial user, for putting their neck out and trying to move forward with the technology.” 

Utilities are not the only private companies looking into advanced nuclear, with Dow Vice President for Energy and Climate Edward Stones saying his firm is interested in using small modular reactors to replace the combined heat and power systems it uses at its factories. The firm has to produce 10 GW of electricity, heat and steam for its 25 major manufacturing sites around the globe. 

Dow is working with X-energy to build four SMRs at its Seadrift facility in Texas, with plans to start construction in 2026 and be operational by 2030. 

“The project will provide the Seadrift site with safe, reliable, zero-carbon-emissions power and steam as the existing energy and steam assets reach their end of life,” Stones said. “The project is expected to reduce the site’s emissions by 440,000 MT CO2e/year.” 

COP28: The World Can’t Afford an ‘Orderly’ Energy Transition

DUBAI — The energy transition will be messy, but mistakes along the way are essential as the world attempts to solve the complex and broken ecosystem that caused climate change, leaders from the industrial and financial sectors said at a McKinsey panel on the net-zero transition.

The panel took place in COP28’s Green Zone, a short walk from the Blue Zone, where governments and NGOs are negotiating commitments and reporting on progress toward the Paris Agreement.

“The idea of orderly transition is a wrongheaded idea,” said Lord John Browne, managing director of climate growth equity fund General Atlantic and co-founder of BeyondNetZero. “It’s testing and trying: no one has the answer.”

This “test and try” approach to solving the energy transition can be seen in everything from incentives to financial structures to supply chains, he said. Governments and industry make mistakes in almost all aspects of the transition, but a poorly designed incentive with unintended consequences is better than no action at all, and those actions help figure out what does work, he added.

Accepting and embracing the three steps forward, one step back nature of the transition is essential, said Tom Linebarger, former CEO and chairman of Cummins, because without it, “it causes people to wait for the perfect solution, for some technologists to deliver something that’s going to be free for everybody and really perfect.”

“We’re going to be disappointed by the side effects of everything from batteries to hydrogen manufacturing. There are going to be things that we didn’t predict, there are going to be things that don’t work the way we want,” Linebarger said. But “if we don’t get started, we don’t solve those problems.

“The question is, how do you move when you know you’re going to make mistakes? How do you get going to take a step forward? That’s really the challenge in front of corporations, investors, people who are trying to advance the cause.”

Too many corporations wait for the risk to be removed, particularly in industries where commodity prices drive decisions, but Linebarger said companies must act in the short run, with the expectation they’ll learn and win over time.

Investing in the energy transition also means accepting that work will need to be redone over time, Browne said. For example, early wind farms are being redone with more powerful turbines, and solar farms built today will be redone when more powerful panels reach the market.

Even with alignment about the problems and commitments being made by governments at COP28 to solve them, there’s a $2 trillion shortfall of the $4 trillion a year needed to reach climate goals, said Anne Finucane, chair of Rubicon Carbon. “You can figure your way to $2 trillion through the market, just based on 20% equity and 80% financing” that’s typical from banks, private equity firms and asset managers. “The question is what to do about the other $2 trillion.”

Carbon taxes are seen as a necessary tool, but there’s no consensus on whether they should be voluntary or required, and whether voluntary carbon taxes are underpricing carbon.

Panelists said private sector funding alone wouldn’t be sufficient to close the investment gap, and that public and private partnerships are essential. “This is a catalytic moment because it will push governments to do the right thing,” Lord Browne said.

Mapping a Path to Net Zero

The panel coincided with McKinsey’s release of a new report: “An Affordable, Reliable, Competitive Path to Net Zero,” which argues for “not one objective, but four interdependent ones: emissions reduction, affordability, reliability and industrial competitiveness.”

Designing an achievable path is critical, said Daniel Pacthod, senior partner at McKinsey, because the world is far from achieving the Paris Agreement targets. “We’ve seen this in the global stock takes: we’re not going to be remotely close to where we want to be. We are closer to 2.5 degrees in, more than 1.5.”

The report looked at seven principles for decarbonization and said applying two principles — deploying lower-cost solutions and using R&D and other measures to double the expected rate of cost declines — “could substantially improve the current trajectory of emissions and help limit warming to what the Paris Agreement envisions.”

While the potential of a pathway based on those principles is hopeful, the report also warned that “a poorly executed transition could make energy, materials and other products less affordable, compromising economic empowerment. It could also make the supply of energy and materials less secure and resilient, and it could render some countries and companies less competitive. If that happened, progress toward net zero itself could stall.”

Whitmer Signs Climate Bills, Including 100% ‘Clean Energy’ Goal

Michigan Gov. Gretchen Whitmer (D) signed a sweeping package of climate legislation into law Nov. 28, setting a 100% “clean energy” target for 2040, expanding energy efficiency programs and making it easier to site renewable projects. 

The seven bills Whitmer signed in a ceremony in Detroit codify many of the goals she set two years ago in her Healthy Climate Plan and add the state to the ranks of those pledging to reach net-zero carbon emissions in less than a generation. 

Whitmer said the bills, passed earlier in November by the Democratic-controlled legislature, would reduce utility bills and create thousands of new jobs. (See 100% Clean Energy, Renewable Siting Bills Heading to Mich. Governor.) 

“With today’s bills, we define the future. As Michiganders, we know we have a responsibility to face climate change head-on, not only to make lives better today, but to make sure life goes on centuries from now,” she said. 

The package includes the Clean Energy and Jobs Act, controversial legislation (HB 5120 and HB 5121) that gives the Public Service Commission power to approve sites for new large-scale renewable energy projects if local governments otherwise try to prevent them. Local government organizations have opposed the measures, setting up the possibility of a court challenge. 

Also signed by Whitmer was the Clean Energy Future Package: 

    • SB 271 expands the current 15% renewable energy standard to 50% by 2030 and 60% by 2035. It also requires 80% “clean energy” — including renewables, nuclear and natural gas with 90% carbon capture — by 2035 and 100% by 2040. The law also sets a 2,500-MW storage target for 2030 and increases the cap on distributed generation such as rooftop solar from 1% to 10%. 
    • SB 273 requires utilities to boost their EE savings from 1% to 1.5% and sets the first-ever requirement for EE programs for low-income residents. 
    • SB 502 requires the PSC to consider environmental justice, climate, affordability and reliability in its decisions on utility integrated resource plans. 
    • SB 519 creates a Community and Worker Economic Transition Office in the Department of Labor and Economic Opportunity to help retrain auto, energy and construction workers who lose jobs because of the switch to electric vehicles and efforts to reduce greenhouse gas emissions. 
    • SB 277 codifies an existing state rule allowing farmers to remain enrolled in the state farmland preservation program even if they rent their land for solar farms. 

The state Department of Environment, Great Lakes and Energy cited modeling by clean energy consulting firm 5 Lakes Energy that predicted the new policies would create nearly 160,000 jobs, cut household energy costs by at least $145/year and enable the state to obtain $7.8 billion in federal funding. 

The right-leaning Mackinac Center for Public Policy, in contrast, said the policies would “raise individual electricity rates by potentially thousands of dollars per year.” 

Some environmentalists criticized legislators for changing the 100% deadline from 2035, defining landfill gas and incinerated waste as renewable energy, and allowing natural gas generators to remain in operation if they include carbon capture.  

Juan Jhong Chung, co-executive director of the Michigan Environmental Justice Coalition, said the legislation “completely misses the mark.” 

“In fact, it opens the door for more pollution in overburdened communities,” he tweeted. “This package reflects the priorities of the utilities and lobbying groups. EJ communities expected more of Michigan’s Democratic trifecta.” 

But many raved about the package, saying the new laws make Michigan a national climate leader. 

Alli Gold Roberts, senior director of state policy for Ceres, said her group supported the package “in partnership with many businesses.” 

Michigan is “now leading the U.S. Midwest in clean energy adoption,” Jeff Bishop, CEO of energy storage developer Key Capture Energy, told Energy Storage News. “We’re going to be seeing legislation like this all throughout the Midwest, and Michigan is just going to be the start.” 

Passage of the legislation, which was opposed by Republicans, was made possible when Democrats gained control of both houses and the governor’s office for the first time since the 1980s.  

“Gov. Whitmer is trying to build her national profile with the Democrat Party,” House Minority Leader Matt Hall told Fox News. “I think in order for her to build her brand with the far left and the Democrat Party, she felt she had to try to one-up them here in Michigan.” 

The Legislature ended voting for the year on Nov. 9 after two Democratic representatives won mayoral races, leaving the House temporarily in a 54-54 tie. 

FERC Approves NERC Standards Process Changes

FERC on Nov. 28 accepted NERC’s proposed changes to its reliability standards development process, but it ordered the ERO to submit a follow-up filing by May 2025 to review the effectiveness of the new provisions (RR23-4).

The changes are intended to streamline the development process and allow a faster response to emerging issues. They will primarily affect section 300 and Appendix 3A of NERC’s Rules of Procedure. NERC’s Board of Trustees approved the revisions at its August meeting in Ottawa and submitted them to FERC for approval the following month. (See “Standards Process Changes Accepted,” NERC Board of Trustees/MRC Meeting Briefs: Aug. 16-17, 2023.)

Section 300 of the ROP provides for “public comment, due process, openness and a balance of interests in developing proposed reliability standards,” FERC’s order noted, while Appendix 3A constitutes the ERO’s Standard Processes Manual (SPM), which sets out how standards are to be developed and revised, along with violation risk factors and severity levels, definitions of terms and reference documents.

Board Authority in ‘Extraordinary Circumstances’

Under a newly added section 322, NERC’s board would have the authority to direct the development of a new or revised standard “in extraordinary circumstances, where the board determines a directive is essential to provide for an adequate level of reliability for the” power grid, an event NERC’s petition called “unlikely and unusual.”

Currently, NERC’s board can make such a directive only when the commission or another governmental body has directed the development of a standard but the ERO’s normal development process has failed to satisfy industry consensus.

If the board does decide to authorize the development of a standard, the new section will require it to provide preliminary written notice, with its reasoning for ordering the standard, and set a public comment period of at least 45 days. Standards the board orders under this new authority will be developed using the SPM and subject to the same requirements for public comment and balloting.

Changes to the SPM include creating a tiered system of comment periods, under which the initial 45-day comment and balloting periods would be followed by shorter comment periods of as little as 30 days, when “appropriate for a smaller number of changes affecting a [smaller] number of standards.” The length of the comment period would be determined by the standards drafting team responsible for the project.

In addition, drafting teams will be allowed to conclude a standards action without a final ballot if the previous ballot received approval from at least 85% of the ballot body; the team has “made a good faith effort at resolving applicable objections” and responded to comments in writing; and no further changes are proposed. If no final ballot is conducted, NERC will provide notice of the outcome as if the ballot had been conducted.

Additional revisions to the ROP include retiring section 316, which “commits the ERO to seeking and maintaining” certification from the American National Standards Institute (ANSI) for its standards development process.

NERC observed in its petition that FERC does not require ANSI accreditation, but that the ERO initially used the process to satisfy the commission’s requirement that its rules provide due process and openness. After “15 years of operating in a unique, multijurisdictional framework,” NERC now believes retiring the ANSI requirement will allow more flexibility in its development approach.

FERC Wants Follow-up in 2025

While the commission agreed with improving the speed and flexibility of the standards development process, it also noted the “need for a timely and responsive … process given the rapid pace of change in the reliability and security of the” grid.

To assess the suitability of the ROP revisions, FERC directed NERC to submit, within 18 months of the commission’s order, an informational report on the effectiveness of the changes and whether any further refinements are needed. FERC said the report should include:

    • data on the ERO’s performance since approval, such as a comparison of development times for standards before and after implementation;
    • discussion of how the revised procedures have helped NERC expedite standards on topics such as resource mix changes, cybersecurity and extreme weather;
    • whether and why any standards have been delayed;
    • recommendations for addressing further concerns with the standard development process; and
    • discussion of how NERC has continued to meet FERC’s requirement of a fair and open process.

Commissioner James Danly did not participate in the decision.

Big Savings for Tx Competition Claimed as FERC Considers a New ROFR

The Electricity Transmission Competition Coalition released a report Nov. 29 arguing that getting rid of competitive forces in transmission development would cost consumers hundreds of billions of dollars on the grid buildout. 

“Without competition, consumers are going to be faced with decades of high electricity inflation,” ETCC Chair Paul Cicio said in an interview. “We all know that transmission is very capital intensive, and even with competition, consumers’ electricity bills are going to go up. But with competition, we can avoid up to on average 40% of the cost of new transmission.” 

That 40% figure would involve more transmission competition than has happened so far. While FERC ended the federal right of first refusal with Order 1000 more than a decade ago, since then just 3 to 8% of all transmission lines have been subject to competition, ETCC said. 

Getting a third of all transmission development subject to competition would save $277 billion on the $2.1 trillion in transmission expansion that Princeton University forecast in its often cited “Net-Zero America” study. If all new transmission projects were open to competitive bidding at an average cost savings of 40%, it would save $840 billion on that buildout. 

Transmission lines can get returns on equity of 10 to 12% for periods lasting 40 years, but competitive bidding can push that ROE down, ETCC said. 

“Competitors can say, ‘Well, instead of accepting a 12% return on equity, our bid on this project is 10%,’” Cicio said. “That automatically is a lower cost to consumers, so competition drives down costs.” 

In its Notice of Proposed Rulemaking on transmission planning, FERC went the other way, finding that total elimination of a federal ROFR for incumbent utilities on transmission lines running through their territories led to “flawed incentives” that might prevent the most efficient transmission from being developed. The NOPR would allow a ROFR to be reinstated as long as utilities work with another party on any lines (RM21-17). (See Battle Lines Drawn on FERC Tx Planning NOPR.) 

“The real concern here is that competition, when you put it in the context of transmission, is a much more complicated issue than it would be, say, in the generation side,” WIRES Group Executive Director Larry Gasteiger said in an interview. “And what we’re seeing in reality is that things are taking longer, because the processes are much more involved.” 

The two largest RTO markets offer different experiences in building out regional transmission lately, with Gasteiger noting that MISO, with its high share of state ROFR laws, is often touted as successful with its Multi-Value Project portfolio. 

“So, in my mind, that kind of calls into question this argument that you need to have competition in order to get transmission done, and to get it the cheapest possible way,” Gasteiger said. 

PJM has a much different process, leaving policy-based lines up to the states driving those needs. Its utilities’ spending on local transmission has often been criticized, including in a complaint by the Ohio Consumers’ Counsel (EL23-105). The OCC alleged that Ohio utilities had unjustly spent $6 billion on local supplemental projects since 2017, pushing up electricity rates. 

Ohio’s utilities have responded that the OCC failed to show any evidence that they are overspending on such projects, and that it should be left to the state to oversee them. Both sides of the broader transmission-competition debate have weighed in on the complaint as well, with WIRES attaching a Charles River Associates report on the benefits of local transmission planning to its comments. 

“Notwithstanding the challenges that there may be with getting regional, and even more so interregional, transmission [built], that doesn’t mean we don’t need a lot of local transmission developed too,” Gasteiger said. “So, the fact that we’re actually just getting something done at the local level doesn’t necessarily mean that is bad, or that it is wrong. What it means is that it’s needed, and it’s actually getting accomplished.” 

ETCC did not weigh in on the complaint, but many of its members did. Cicio noted that it highlights another part of ensuring costs are low for customers as the grid expands. 

“There’s the oversight to make sure that we need the project,” Cicio said. “The second part, if we need the project, it needs to be competitively bid, so that it reduces costs. It’s a two-step process.” 

ETCC’s report, titled “FERC’s $277 Billion Electricity Price Hike,” focuses on consumer costs, reporting that the price of electricity has outstripped inflation in recent months, despite declines in the cost of other energy commodities including gasoline and fuel oil. One in five U.S. households have struggled to make a utility payment in the past year, and 26% of homes have experienced energy insecurity, it says, citing data on energy affordability from the U.S. Census Bureau. 

“Even the Federal Trade Commission and the Department of Justice of this Biden administration weighed in, in writing, to FERC saying: ‘FERC, do not back away from competition,’” Cicio said. “And, so, we hope that they will do the right thing and strengthen Order 1000 and require all projects that are 100 kV or larger to be competitively bid.” 

Gasteiger did not push back against the census data, but he did question whether transmission competition would really save hundreds of billions of dollars in future investments. 

“Their savings projections are just that: They’re projections,” he said. “They’re hotly contested. And the track record shows that they’re often not reliable.” 

Ultimately, these questions will be answered by FERC whenever it issues its final rule, he said. 

WIRES does not want to see competition for transmission expanded, arguing that would delay transmission that is successfully getting built under the current regulatory model. Competitive transmission might work for the very-hard-to-build lines that stretch across multiple states to ship renewable power long-distance, or in similar transmission projects that help meet public policies, Gasteiger said. 

“See if you can get it to work, and then build on that,” Gasteiger said. “But if not, don’t just automatically start expanding into areas where we’re actually getting transmission built and jeopardize the ability to get that transmission built as well.” 

FERC Approves Agreement Resolving Versant Audit Issues

FERC approved an agreement among Versant Power, the Maine Public Utilities Commission (PUC) and Maine Office of the Public Advocate (OPA) related to improperly classified expenses that resulted in the overbilling of wholesale transmission customers (ER23-1598).

The issues were first identified in a 2021 audit report issued by the Commission’s Office of Enforcement, which found that Versant improperly capitalized about $18 million in overhead costs, causing the company to overcharge transmission customers.

The company issued refunds in May 2022 and filed in April 2023 to recover some of the overhead costs over an extended period.

The Maine PUC protested this filing, expressing concern about its lack of refunds for retail customers, the potential double-charging of retail customers during the recovery process, and the potential for the proposal to “improperly result in wholesale and retail customers paying Versant a rate-of-return on improperly collected costs.”

In September, Versant submitted an agreement signed by the company, the PUC and OPA to resolve the issues raised by the PUC and establish a process for the company to recover the overhead costs.

The parties agreed to amortize about $15.6 million over eight years, intended to account for the difference between the overhead costs and the refunds owed to retail customers.

On Nov. 28, FERC ruled the agreement “appears to be fair and reasonable and in the public interest and we therefore approve it.”

A spokesperson for Versant told RTO Insider the settlement is fair and “beneficial to both the company and our customers.”

CARB to Consider Transferable ZEV Truck Credits

The California Air Resources Board is exploring whether zero-emission truck credits that manufacturers earn under the Advanced Clean Trucks regulation should be transferable among states. 

Truck manufacturers say they need the flexibility of credit transfers — also known as credit pooling — to comply with the regulation, particularly in its early years. Advanced Clean Trucks (ACT) requires medium- and heavy-duty truck manufacturers to sell an increasing percentage of zero-emission vehicles each year in states that have adopted the rule. 

In addition to California, eight states have adopted ACT: Massachusetts, New Jersey, New York, Oregon, Washington, Vermont, Colorado and New Mexico. 

But officials in ACT states say that if the required zero-emission trucks go to other states, they’ll lose out on air quality and climate benefits of the vehicles. 

The debate played out during a CARB workshop on Tuesday regarding ACT credit transfers. 

“All pathways to achieving our greenhouse gas reduction targets require switching from fossil fuel vehicles to zero-emission vehicles,” said Rachel Sakata, transportation strategies section manager in the Oregon Department of Environmental Quality. “And given the urgency of the climate crisis, it is crucial that this transformation accelerates to scale as soon as possible.” 

But Tim French of the Truck and Engine Manufacturers Association said that without credit pooling, manufacturers might have to resort to reducing sales of all trucks in a particular state so they can meet the percentage sales requirement. 

“Without credit pooling — and not to be alarmist — there is an increased risk of product shortages in the opt-in states,” French said during the workshop. 

James Clyne with the New York State Department of Environmental Conservation said ACT already gives manufacturers flexibility through measures including credits for early ZEV sales, credit banking and trading, and some credit for near-zero-emission vehicles. 

“The underlying concern in [ACT] states is that pooling could water down ACT sales requirements,” Clyne said. “Flexibility already exists. It is imperative as a first step to determine whether pooling is warranted at all.” 

Clean Truck Partnership

The discussion of pooled credits results from an agreement announced in July between CARB and leading truck manufacturers. (See CARB, Manufacturers Partner to Support Clean Truck Rules.) 

Under the deal, known as the Clean Truck Partnership, truck makers agreed to sell as many zero-emission trucks as reasonably possible in every state that has adopted ACT, even if there are legal challenges to the regulation. 

In exchange, CARB promised to provide more compliance flexibility in ACT. That includes giving manufacturers three years, rather than one year, to make up deficits in meeting ZEV requirements. CARB also committed to holding a workshop this year to discuss ZEV credit pooling. 

CARB released draft text this month for potential ACT amendments, including the increase to three years for making up deficits. CARB staff said their goal is to finalize the rulemaking in 2025. 

Light-Duty Rules

Credit pooling is part of CARB’s zero-emission rules for light-duty vehicles, Advanced Clean Cars II. Manufacturers can use excess ZEV or plug-in hybrid credits to meet a portion of compliance requirements in another state. Credits can be transferred only to fill a deficit. 

In its 2012 version of Advanced Clean Cars, CARB established east and west regions for credit pooling, with California excluded. Manufacturers faced a 30% premium for transfer between the two regions, according to CARB staff. 

But pooling was not included in ACT when CARB adopted it in 2020. 

ACT will take effect in California starting with model year 2024 trucks. The effective date varies in other states but starts as soon as model year 2025 in Massachusetts, New Jersey, New York, Oregon and Washington. 

CARB announced last month that about 8,900 zero-emission trucks from model years 2021 and 2022 have been sold in California or are expected to be sold based on uptake of incentives. That’s about 60% more than the 5,500 ZEVs that CARB estimates will be needed to meet the model year 2024 quota. (See California Far Outpacing Clean Truck Targets.) 

NYISO Management Committee Briefs: Nov. 29, 2023

Internal Controllable Lines

NYISO’s Management Committee voted Nov. 29 to approve tariff revisions establishing market rules for “internal controllable lines” (ICLs), recommending they be approved by the Board of Directors.

The ISO’s Business Issues Committee previously approved the provisions, which set energy market, capacity market and market mitigation rules for ICLs. Clean Path New York, a 175-mile, 1,300-MW HVDC line selected as a Tier 4 project to deliver renewable power from upstate to New York City, will soon become the state’s first ICL. (See “Internal Controllable Lines,” NYISO Stakeholders Advance Rules on Ambient Ratings, Internal Controllable Lines.)

The changes seek to optimize ICL flows through economic dispatch and prohibit bilateral energy market transactions using ICLs as their source or sink. Additionally, ICLs will have defined operating ranges, bid curves and ramp limits to ensure system stability.

If approved by the board, the rules are expected to be filed with FERC in the first quarter of 2024.

Ambient-adjusted Ratings

The MC also moved to approve and recommend the board approve tariff revisions aligning day-ahead market (DAM) congestion settlement procedures with ambient-adjusted ratings (AARs).

FERC Order 881 requires transmission providers to evaluate transmission capacity based on real-time environmental conditions and mandates the use of AARs for short-term transmission requests, and seasonal ratings for long-term requests (RM20-16).

The ISO’s proposed revisions address discrepancies between AAR rating limits in the DAMs and those used in transmission congestion contract (TCC) auctions. The changes revise calculations for the congestion rent impacts of uprates and derates and create a new category of qualifying events, which emerge from differences between the DAM ratings required by Order 881 and those assumed in TCC auctions.

The BIC also previously approved these revisions. (See NYISO Stakeholders Advance Rules on Ambient Ratings, Internal Controllable Lines.)

If approved by the board, the ISO plans to implement these revisions alongside compliance proposals already accepted by FERC.
