FERC Approves Changes to ISO-NE DER Interconnection Process

FERC last week accepted ISO-NE’s proposed changes to its process for interconnecting distributed energy resources, finding them just and reasonable with some clarifications (ER22-2226).

Previously, some DERs had used the ISO-NE interconnection process, while others used state interconnection processes, a disconnect that the grid operator said “results in multiple coordination problems and inefficiencies that in some cases result in adverse outcomes for DER developers.”

ISO-NE proposed that all new DERs proceed through the applicable state processes to ease the uncertainty. (See ISO-NE Sends New DER Interconnection Proposal to FERC.)

In an order on Friday, FERC agreed that the change makes sense.

“We find that ISO-NE’s proposal to exclude DERs from its interconnection procedures is just and reasonable because it would promote certainty in ISO-NE’s interconnection process and reduce a significant burden on ISO-NE,” the commission wrote.

FERC also clarified that “the commission’s jurisdiction over wholesale sales from DERs and their participation in the wholesale markets are not impacted by the change.”

The Solar Energy Industries Association, Advanced Energy Economy and ENGIE North America had all backed the changes, saying they would help resolve unique concerns in New England because of the growth of DERs in the region.

After FERC’s approval, the tariff changes went into effect Sunday.

ISO-NE’s proposal concerned individual DERs; as such, it is separate from its compliance with FERC Order 2222, which deals with DER aggregations. In concluding its order, the commission noted that, as it had in Order 2222, it “may revisit this independent entity variation in the future should [it] discover abuses of the distribution interconnection process or the rise of unnecessary barriers to the participation of distributed energy resources in RTO/ISO markets.”

Texas RE Board of Directors Briefs: Aug. 24, 2022

NERC Cold Weather Standard Development Coming to Close

AUSTIN, Texas — A member of the NERC team drafting the industry’s new cold weather standard told the Texas Reliability Entity Board of Directors last week that the standard is on track to be approved in October.

Occidental Power Services’ Venona Greaff, also a member of Texas RE’s Member Representatives Committee, told Texas RE staff and its directors Wednesday that the standard has been posted for a second round of industry comments. The posting expires Sept. 1.

“There was a lot of effort put in by members of the drafting team, but also by industry,” Greaff told ERO Insider, speaking for the team. Stakeholders “took their first pass at it and felt like they at least had a good starting point. Industry provided a lot of valuable feedback, and the drafting team did everything they could to incorporate that feedback … to get to where we’re at now.”

The new standard for extreme cold-weather preparedness and operations (EOP-012-1) is part of Project 2021-07 (Extreme Cold Weather Grid Operations, Preparedness, and Coordination), which NERC started last year in response to the mass outages caused by the February 2021 winter storm. The standard includes four new requirements and strengthens several existing requirements that address reliability-related findings by NERC, FERC and regional entity staff.

The standard will require generator owners to implement freeze-protection measures so the units can operate for at least 12 continuous hours in extreme cold weather, defined as the temperature equal to the lowest 0.2 percentile of the hourly temperatures measured in December, January and February from January 2000 to present day.

Generator owners will also be responsible for ensuring their units add new or modify existing freeze-protection measures as needed to be able to operate for at least an hour during extreme cold-weather temperatures. Those units not able to meet the one-hour standard will be required to develop a corrective action plan (CAP) for modifications to a cold-weather preparedness plan.

“We’re hopeful that it is something that industry is satisfied with and can get on board with and improve,” Greaff said.

The cold-weather standard will be effective with the 2023 winter season.

NERC’s Board of Trustees will hold a special meeting in October to vote on the standard. It will then go to FERC for final approval.

New Braunfels Chief Discusses Challenges

In a keynote presentation, New Braunfels Utilities (NPU) CEO Ian Taylor said that while the ongoing transformation of the electric grid is “absolutely exciting,” it has also created challenges for utilities across Texas.

“Even [with] foundational activities like procurement and budgeting, what we’ve done in the past is just not adequate anymore for what we’re being called to do,” Taylor said. “We’re adding tools [and] expertise; we’re redefining and creating processes to be able to handle the type of work that we’re [doing]; and then we’re also having to recreate our workforce. …

“You’ve got to recalibrate folks to think critically and analytically in ways they’ve never done before. That takes some work; it doesn’t just come naturally.”

One of the topics that Taylor touched on was the effect of last February’s winter storm, which resulted in more than 23 GW of manual firm load shed, mostly in Texas. NBU itself experienced a number of equipment failures during the crisis, including 21 transformer failures and three downed wires, but it reported no transmission issues.

While the storm was “a significant emotional event” for NBU — a publicly owned provider of water, sewer and electric services in Texas’ Hill Country — Taylor was proud that the utility had no outages on its system after the end of rotating outages and only one tree-related outage during the event. In addition, the crisis was a chance to test NBU’s procedures and see where they came up short when confronted with a real disaster.

“We’ve always had an emergency management plan, but this gave us an opportunity to really go in” and revise the work the utility had done before, Taylor said.

“We got some minimum inventory levels that we didn’t really have formalized before, and lots and lots of lessons learned and coordination with local government entities that came out of that,” he continued.

Fall Workshops Scheduled

The Texas RE has scheduled a pair of workshops this fall focused on grid resilience, security and reliability.

A two-day Extreme Events Resiliency Workshop will be held Sept. 20-21 at a yet-to-be-determined location. Staff will moderate a series of panel discussions with industry experts on planning for and maintaining resilience during both natural and manmade extreme events.

ERCOT staff and state regulators overseeing the electric and gas industries will also be on hand to update attendees on their winterization activities.

Texas RE will host a Standards, Security and Reliability Workshop on Oct. 27 in its Conference Center. Virtual attendance will also be offered.

In other actions, the board’s Nominating Committee put up incumbent independent Directors Crystal Ashby and Jeff Corbett for additional three-year terms, effective January 2023.

Texas RE’s First In-person Meetings

The board and MRC meetings marked the Texas RE’s first in-person meetings since February 2020, just before the COVID pandemic began, and the first in its new office space located conveniently in the same complex as ERCOT’s new headquarters building.

“Every time I think about the date, I [say], ‘It can’t be over two years.’ But it has been,” board Chair Milton Lee said. “This meeting in person has been fantastic. I’m grateful the building was completed. Let’s hope we can continue to meet person-to-person without going back to virtual.”

“We’re still working on the technology in this room,” Texas RE CEO Jim Albright said, referencing several audio problems. “By 2023, we hope we’ll be full bore in how we’re going to have this meeting. You’re kind of the guinea pigs today.”

The board last year approved the entity’s request for a 20% budget increase to $17.2 million to help cover additional staff and relocation costs for the new space. Staff said it will save about $1.3 million over a 10-year period with the move. (See Texas RE Asks for 20% Budget Increase.)

SACE Urges FERC Inquiry into Proposed TVA Gas Plant

The Southern Alliance for Clean Energy (SACE) has protested with FERC that the Tennessee Valley Authority’s justification behind a new gas plant’s construction is faulty, urging the commission to conduct its own assessment into the resource’s need.

TVA has proposed a natural gas plant and a 32-mile pipeline to replace its coal-fired Cumberland Fossil Plant northwest of Nashville. The alliance said the federal agency would be better served with a blend of large-scale and distributed solar, wind and storage resources and energy efficiency measures.

SACE’s protest was registered in a docket related to Tennessee Gas Pipeline Co.’s request for FERC permission to build the gas pipeline. The alliance was among several public-interest groups that urged TVA in June to rethink its plans after the agency filed its environmental impact statement (CP22-493). (See Nonprofits Urge TVA to Reconsider Gas-fired Options.)

SACE repeated its position that the draft EIS isn’t a reliable document and lacks a transparent analysis to support it. The alliance said FERC should assess other alternatives. It said the draft clings to an outdated and rosy natural gas price forecast and said it is based on TVA’s 2019 integrated resource plan, which used assumptions made from 2016 to 2018 and predates President Joe Biden’s executive order that calls for net-zero carbon emissions in the electric sector by 2035.

“Were TVA to build a new carbon-emitting gas CC at Cumberland by 2026, with no plans for capturing the carbon, it will immediately become a stranded asset in less than a decade and thus add to the utility’s costs that must be borne by the 10 million people it serves,” SACE said.

It also said the federal agency didn’t consider the possibility of energy efficiency programs offsetting some demand or importing wind power into its territory.

“Since TVA is currently lagging the Southeast in energy efficiency savings, a region that lags the country in energy efficiency savings, and the National Renewable Energy Laboratory estimates there is substantial energy efficiency potential in just Tennessee alone, it is absolutely reasonable to assume that energy efficiency would be a cost-effective addition to a clean energy portfolio replacement,” SACE argued.

The alliance also suggested that TVA executives may have a conflict of interest, noting they receive millions in bonuses tied to the availability of coal and gas plants but don’t have any incentives attached to expanding renewable energy or energy efficiency.

SACE said there is no evidence that TVA took any steps to meaningfully evaluate other Cumberland replacement plans.

“These actions could have included issuing a request for proposals for renewable energy and energy storage resources, staffing up its interconnection study department to prepare to interconnect renewable energy projects faster, identify and begin planning transmission projects to ease the integration of renewable energy projects and beginning to set up energy efficiency programs and other demand-side measures,” SACE said. “TVA’s actions to date make it very clear that it always intended for the gas [combined cycle] option to be its preferred option regardless of the environmental review process, and that brings the merit of its environmental review into question.”

The Sierra Club and Appalachian Voices also filed protests in the docket. They said the Tennessee Gas Pipeline “can offer no reliable evidence that its only customer, TVA, will ever be able to move forward with its plans.”

“The proposed power plant would emit millions of tons of greenhouse gases each year, rendering it incompatible with the President’s executive orders on climate change, dependent on a volatile and increasingly expensive fuel, and more costly than an available suite of clean energy resources,” the environmental advocates said.

The Sierra Club and Appalachian Voices also urged FERC to “independently evaluate the need” for Cumberland City and the pipeline and consider “clean energy alternatives that could replace both at lower cost to ratepayers.” It said the commission’s examination is needed because TVA lacks meaningful oversight and competition.

TVA maintains that it hasn’t made a final determination regarding its natural gas plant plans.

“TVA has not made any decisions about the future of that plant nor replacement options, pending completion of the [National Environmental Policy Act] process later this year,” spokesperson Ashton Davies said in a statement to RTO Insider.

TVA stressed that it is not involved with the construction of the pipeline or its permitting and regulatory process. Davies said the utility would merely be a customer of the pipeline should it elect to construct a gas-fired plant.

“TVA is supportive of the project as it would be a likely source for natural gas, should TVA choose that option to replace capacity at Cumberland Fossil Plant,” Davis said.

SPP Briefs: Week of Aug. 22, 2022

Platte River Joins Western Utilities Evaluating RTO Membership

SPP on Thursday welcomed Colorado utility Platte River Power Authority as the latest Western utility to provide a notice of intent to evaluate participation in the grid operator’s planned RTO West.

Platte River is the eighth Western entity that has publicly committed to exploring SPP’s RTO expansion. The utility has already announced plans to join the RTO’s Western Energy Imbalance Service (WEIS) market next April.

“We look forward to joining the WEIS next year and SPP’s RTO in 2025,” Platte River COO Melie Vincent said.

SPP administers the WEIS market on a contract basis and provides participants with a suite of services including market administration, transmission planning, reliability coordination and more. It says WEIS participants that become full RTO members can expect to receive similar savings and benefits as its Eastern Interconnection members. According to the grid operator, those members saved $2.696 billion last year, a benefit-to-cost ratio of 18-to-1 given $149 million in net revenue requirement costs.

The RTO has set a March 2023 target for Western utilities to indicate their intent to participate in its initial expansion into the interconnection. SPP expects to extend its RTO into the West in March 2024.

“We are pleased that Platte River will be joining the WEIS market next year and is evaluating the cost and benefits of full RTO membership,” said Bruce Rew, SPP’s senior vice president of operations. “Our continued collaboration will enable us to help them reliably and economically serve their communities while meeting their clean energy goals.”

Basin Electric Power Cooperative, Colorado Springs Utilities, Deseret Power Electric Cooperative, Municipal Energy Agency of Nebraska, Tri-State Generation and Transmission Association, Western Area Power Administration and Wyoming Municipal Power Agency are the other entities that have already expressed interest in the RTO.

MMU Releases WEIS Spring Report

SPP’s Marketing Monitoring Unit (MMU) last week released its WEIS quarterly State of the Market report for the spring period, which covers March through May 2022.

The MMU said it believes that the WEIS “functioned as expected” during its second spring quarter of operations. It said the market continues to struggle with ramp availability and short-term system flexibility despite an abundance of online capacity but noted those issues have persisted since it began operations in February 2021.

The Monitor said many dispatchable resources are offered with minimal available dispatchable and/or rampable capacity. “Market participants are also reluctant to offer additional resources due to risks associated with recovering costs when prices drop,” the MMU said.

It noted SPP has begun conversations with market participants to discuss offered rampable capacity and encourages more capacity to be offered to increase market efficiency. “The MMU supports the incremental improvements to the market enacted during this period and continues to recommend further enhancements,” it said.

Average load prices during the period were consistent with the year prior at $15.71/MWh and $19.48/MWh for March and April, respectively, and increasing to $26.85/MWh in May. Coal remained the predominate fuel source ahead of hydropower, accounting for 66% of the market’s generation in March before dropping to 59% by May.

SPP administers the market for 12 utilities, centrally dispatching energy from participating regional resources every five minutes.

RTO, AECI to Target Efficient Joint Solutions

SPP staff told stakeholders last week that they will be taking additional steps this year as they work across the seam with a neighboring cooperative to identify interregional projects.

Neil Robertson, the RTO’s coordinator of system planning, said during a joint stakeholder planning meeting with Associated Electric Cooperative Inc. (AECI) on Wednesday that the staffs are going to work with local transmission owners to find the best solutions for their needs.

“In years past, I felt soliciting for transmission solutions for all the needs was not efficient. As we refined [the solutions], we discovered we might not have a true jointly funded opportunity,” Robertson said.

SPP has already analyzed updated models and contingency files provided by AECI and found more than 90 thermal and voltage needs. He promised a review of proposed solutions and to discuss potential joint projects when staff next meet with AECI and stakeholders later this year.

“We got some good project solutions, but when we’ve looked at that through a joint system plan with AECI, the benefits went to one or the other,” Robertson said. “In this refinement, we’ll do some additional due diligence to ensure that the opportunities that move forward clearly demonstrate a shared reliability need and shared benefits. I think this will increase overall efficiencies.”

RFP out for NM Project

SPP has issued a request for proposals in soliciting bids for the 345-kV Crossroads-Hobbs-Roadrunner project in eastern New Mexico.

Companies soliciting proposals will need to include a $50,000 deposit for each response. Each deposit will be held in a segregated interest-bearing account in the respondent’s name.

Notices of intent to submit an RFP response are due Nov. 23. The final deadline for responses and deposits is Feb. 21, 2023. A pre-response open meeting will be held Sept. 23 for qualified RFP participants to ask questions and get feedback.

The project, proposed by Southwestern Public Service, was approved in July as part of the 2021 Integrated Transmission Plan. The project was re-evaluated after load-projection errors were discovered in the original solution. (See “Members Approve SPS Tx Project over Staff’s Recommendation,” SPP Board of Directors/Members Committee Briefs: July 26, 2022.)

Staff said in July the project would likely qualify as competitive under FERC Order 1000. The grid operator has already awarded four such projects.

PJM Markets and Reliability Committee Briefs: Aug. 24, 2022

Discussions Continue on Market Seller Offer Cap

VALLEY FORGE, Pa. — Load interests continued to oppose PJM’s proposal to change the market seller offer cap (MSOC), a month after it failed to meet the two-thirds endorsement threshold at the July 27 Markets and Reliability Committee meeting.

The proposal, which would ensure sellers are always able to represent the cost of their Capacity Performance (CP) risk when offering into the Base Residual Auction, had won only 60.4% support, as load sector stakeholders expressed concern over its impact on capacity prices. (See Change to PJM Market Seller Offer Cap Falls Short.)

The rule change would set the MSOC at the greater of the CP quantifiable risk (CPQR) or net avoidable-cost rate (ACR) inclusive of CPQR. PJM said it would address circumstances in which a unit with a positive CPQR value has that cost offset by an otherwise negative net ACR, which could result in a $0 offer cap. PJM had hoped to win stakeholder and FERC approval for the change effective with the 2024/25 capacity auction in December.

Load interests remained cool to the idea at the MRC on Wednesday.

Gregory Carmean, executive director of the Organization of PJM States Inc. (OPSI), asked PJM’s Pat Bruno why it was in buyers’ interests to “pay upfront the default costs of a supplier.”

“We think it’s in consumers’ interests to achieve competitive outcomes in the auction results,” Bruno responded. That result, he said, is “clearing the cheapest set of resources including the risk of nonperformance.”

Susan Bruce, representing the PJM Industrial Customers Coalition, suggested more work was needed before considering the proposal. “Are we ready for prime time with this vote?” she asked.

Independent Market Monitor Joe Bowring said PJM’s proposal would displace the Monitor’s role in setting the offer cap and fails to adequately define CPQR.

“We do not agree that what’s being proposed is a competitive outcome, or that it’s a narrow change,” he said. “You simply can’t have an unlimited adder that’s not defined in the tariff.”

Bowring said not using net energy revenues as an offset to CPQR breaks the “essential link” between the energy market and the capacity market, which generally means lower capacity prices when energy market prices are high. Because PJM has not defined how it would calculate the CPQR or the asserted opportunity cost, the RTO cannot say that the impact would be small, Bowring said.

Carl Johnson, representing the PJM Public Power Coalition, said his members agree with Bruce’s and Bowring’s concerns.

“I’ve become convinced we cannot have this discussion separate from the holistic” discussions at the Resource Adequacy Senior Task Force, he said. The proposal “is such an open door to market power that I don’t see how PJM could effectively mitigate it.”

However, Johnson said his members “do want to represent CPQR in their offers, so they wouldn’t go as far as [Bowring] recommended.”

Jason Barker of Constellation Energy said PJM’s proposal is “consistent with real-world economic decisions” that generation owners are making.

“PJM’s proposal is welcome; it’s ready; and it solves a very distinct problem that sellers encounter time and again,” he said. “A compulsory capacity commitment is not risk-free.”

Manuel Esquivel of Enel North America also expressed support, saying the status quo is not just and reasonable.

Tom Hoatson of LS Power also called for change to the offer cap, saying current rules result in “over-mitigating.” He said his company supports the PJM proposal with several revisions, including that the CPQR should be based on the market seller’s view of the risk of taking on a capacity obligation.

“This risk is viewed differently by different market sellers, and the market seller’s view of this risk is commercially sensitive,” he said. “One size doesn’t fit all, and the process needs to reflect that.”

LS Power also would change the deadline for requesting an exception to the must-offer requirement, making it at least five days after receipt of the final unit-specific MSOC value from PJM and the IMM. The current deadline is the same day as when the final MSOC is issued.

Hoatson also said all models, data and methodologies that the Monitor and PJM use to make their determinations should be made available to the market seller before their decisions are made.

Under the current rules, “it’s a black box,” Hoatson said. “We don’t know how the numbers were arrived at, so we can’t debate them with the IMM and PJM. Perhaps we’re wrong. Perhaps the other side is wrong. We don’t know.”

GreenHat Payments Expected by January

PJM Assistant General Counsel Mark Stanisz told members that the RTO should receive $1.375 million in disgorgements from the principals of the defunct GreenHat Energy by the end of January.

Under settlements approved by FERC on Aug. 19, two of GreenHat’s founders and the estate of the third agreed to pay the disgorgements. The principals also consented to the entry of a $179.6 million judgment against the company, reflecting the losses suffered by PJM market participants when GreenHat defaulted on its obligations in the financial transmission rights market in 2018. (See FERC OKs GreenHat Settlements.)

But PJM has no hope of recovering any of the nearly $180 million, Stanisz said. GreenHat “has no funds and no assets,” he said.

FERC ordered PJM to distribute the disgorged monies “in a reasonable manner” approved by the commission’s Office of Enforcement. The RTO said it will likely do so in a single distribution.

In response to a request from Constellation, PJM said it would advise market participants where they will see the disbursements in their billing statements.

Revised Bankruptcy Rules

PJM proposed changes to its credit policies to provide greater protections against bankruptcies by market participants, the RTO’s latest response to the GreenHat default.

The revisions would clarify that PJM has a first priority security interest in market participants’ cash deposits.

PJM would also require that a party filing for bankruptcy immediately address the RTO’s rights with a “first day” motion ensuring the full repayment of pre-petition obligations and the continuation of post-petition obligations.

The new language aims to demonstrate to bankruptcy courts that PJM has interests that are set apart from “garden variety” creditors, Assistant General Counsel Eric Scherling told the MRC. Though there are limitations on PJM’s ability to compel action from parties that have filed for bankruptcy, the revisions are aimed at making the proceedings go more smoothly to mitigate potential losses from delays.

“PJM is different, and we want to basically do whatever we can … to lay the groundwork as to why PJM is different,” Scherling said.

Tariff language would be changed to clarify that FTR transactions “are entitled to the special protections given to ‘forward contracts,’ ‘swap agreements’ and ‘master netting agreements’” under the U.S. Bankruptcy Code, including exceptions from automatic stays and allowing for immediate termination or liquidation.

The revisions were endorsed by the Risk Management Committee in July after meeting to discuss the issue six times. The proposal is expected to go before the MRC for approval next month.

FERC already approved revisions to PJM’s credit policy for FTR transactions in September 2018, setting a minimum credit requirement for FTRs equal to 10 cents/MWh (ER18-2090).

FTR Manual Changes Endorsed

The MRC endorsed revisions to Manual 6: Financial Transmission Rights as part of a periodic review and changes to conform with tariff revisions intended to increase the transparency and efficiency of the RTO’s auction revenue rights and FTR markets. The changes were approved by FERC in March (ER22-797). (See FERC Accepts PJM ARR/FTR Market Changes.)

Variable Environmental Costs and Credits Rules OK’d

Members approved an update to rules governing variable environmental charges and credits and their inclusion in cost-based energy offers. Generation units receiving production tax credits or renewable energy credits must reflect them in their fuel-cost policies when submitting non-zero cost-based offers into the energy market. The changes will include revisions to Manual 15: Cost Development Guidelines and Operating Agreement Schedule 2. (See “Variable Environmental Costs and Credits,” PJM MIC Briefs: May 11, 2022.)

Johnson thanked PJM for addressing Old Dominion Electric Cooperative’s concerns regarding differentiating fuel costs from emissions costs.

The update will be brought to a Members Committee vote in September.

No Consensus on PJM Capacity Parameters

VALLEY FORGE, Pa. — PJM members failed to find consensus on any of four proposed sets of capacity auction parameters Wednesday, with the RTO’s proposal winning support from slightly more than half of members but falling below the necessary two-thirds threshold.

Proposals by the Independent Market Monitor, Calpine and GT Power Group in the 2022 Quadrennial Review all received less than 50% support in the sector-weighted votes. (See “2022 Quadrennial Review,” PJM MRC/MC Briefs: July 27, 2022.)

The parameters include the shape of the variable resource requirement (VRR) curve, the cost of new entry (CONE) for each locational deliverability area, and the methodology for determining the net energy and ancillary services (E&AS) revenue offset.

PJM’s proposal received a sector-weighted vote of 52%, with support of most Transmission Owners, Electric Distributors and End-Use Customers, but little support from Other Suppliers or Generation Owners. GT Power’s proposal on behalf of Cogentrix was the second favorite, winning 41%, with most support from the GO and OS sectors. The Monitor and Calpine packages trailed with 22% support each. Only 16% favored retaining the status quo parameters without changes.

Immediately after the meeting, the Members Committee approved a motion to forward the results of the MRC vote to the Board of Managers. The board is expected to file changes with FERC by Oct. 1; the changes would be effective with the July 2023 capacity auction.

Packages Explained

While PJM’s proposal includes major maintenance in variable operations and maintenance for recovery in the energy market, the Monitor’s would provide for recovery through the capacity market.

Both Calpine’s and GT Power’s proposals would continue to use historic net E&AS offsets, rather than switching to forward-looking as proposed by PJM and the Monitor.

GT Power’s would also continue to use a combustion turbine rather than a combined cycle plant as the reference unit because of the latter’s greater dependence on volatile E&AS revenues. All other packages would switch to the combined cycle plant.

CEJA Impact

Before the vote, economist Paul Sotkiewicz, representing generator J-Power USA, said the rules for the ComEd zone should reflect the shortened lifespan for new fossil-fired generation as a result of the Illinois Climate and Equitable Jobs Act (CEJA), which requires the state to move to a 100% carbon-free power sector by 2045.

Melissa Pilong 2022-08-24 (RTO Insider LLC) FI.jpgMelissa Pilong, PJM | © RTO Insider LLC

Sotkiewicz said the gross CONE will need to be updated to reflect the shortened economic life of new fossil units, noting a gas plant that went into service in 2026 would have only a 19-year lifespan rather than the 20-year assumption. “You can look at the [Illinois] legislation,” he said. “It’s clear as day.”

PJM’s Melissa Pilong said RTO staff had determined that no change in the lifespan was currently required.

Although PJM’s tariff mandates consideration of the parameters every four years, “nothing prevents us from changing parameters between Quadrennial Reviews,” MRC Chair Stu Bresler said.

DC Circuit Ruling

Sotkiewicz said PJM’s position ignored the D.C. Circuit Court of Appeals’ Aug. 9 ruling setting aside FERC’s order in April that rejected NYISO’s use of a 17-year assumed lifespan for a peaking plant in its capacity parameters (21-1166).

NYISO had cited the New York Climate Leadership and Community Protection Act (CLCPA), which mandates that by 2040, “the statewide electrical demand system will be zero emissions.” The ISO concluded that a gas-fired plant built between 2021 and 2025 would have an average lifespan of 17 years because the CLCPA “requires electricity demand in New York to be served by 100% zero-emission resources” by 2040.

FERC rejected NYISO’s proposed amortization period and required it to return to 20 years, noting that the CLCPA allowed the state’s Public Service Commission to relax the emissions rules if needed to maintain reliability (ER21-502-001). FERC said the ISO’s proposal was “premised on the speculative assumption that all fossil-fueled resources will cease operation in 2040.”

The D.C. Circuit granted the appeal of the Independent Power Producers of New York’s (IPPNY), noting that FERC’s review of Federal Power Act Section 205 filings is limited to whether the proposed rates are reasonable and not whether the proposal is more or less reasonable than alternative designs. The court said FERC’s decision to reject NYISO’s filing based on the possibility that the PSC might alter the CLCPA’s requirements was “squarely inconsistent with its precedents.”

FERC can abandon its precedents as long as it provides reasoned explanation for its action and acknowledges that it is changing its position, the court said. “FERC’s order neither recognized nor explained its departure from precedent,” it said. “That was arbitrary.”

The Sierra Club’s Casey Roberts said the D.C. Circuit ruling was unpublished and lacked much detail. “I don’t think it requires upending the Quadrennial Review,” she said.

Greg Poulos, executive director of the Consumer Advocates of the PJM States (CAPS), said the review “has been a great process,” although he said “most advocates still have a concern about over-procurement. It’s something that costs consumers billions.” He said most advocates would support the Monitor’s proposal.   

Susan Bruce, of the PJM Industrial Customer Coalition, said the ICC supported both the PJM and IMM proposals. The loss-of-load expectation (LOLE) was “much higher” for the other proposals, she said. The others also produce results far beyond the one-day-in-10-years LOLE reliability standard, increasing customers costs.

Roberts said the most recent capacity auction procured 13 GW in excess of the RTO’s reliability requirement.

California PUC Postpones NEM Decision Amid Pressure

The California Public Utilities Commission on Thursday approved a one-year postponement of a decision in its net energy metering rulemaking, as parties on both sides of the issue argued that the Inflation Reduction Act, signed by President Biden last week, supports their views on rooftop solar credits.

The CPUC passed the order extending the deadline for its decision in a unanimous vote on its 35-item consent agenda. Commissioners did not discuss the move, despite its significance and the controversy that has engulfed the CPUC ever since it issued a proposed decision in December to slash solar credits and charge owners for grid participation in a new net energy metering (NEM) tariff. (See California PUC Proposes New Net Metering Plan.)

“An extension of the statutory deadline until August 27, 2023, is necessary to allow adequate time to complete this proceeding,” the order said, citing the need to digest a flood of comments and consider alternative approaches.

The proposed decision was released on Aug. 15. (See CPUC to Delay Net Metering Decision for a Year.)

As in many of its voting meetings this year, the bulk of the CPUC’s session Thursday consisted of public comments on the NEM proceeding, mainly from homeowners upset about the proposed changes.

Their latest target was a filing by the state’s three large investor-owned utilities contending that the extension of federal credits for rooftop solar in the IRA made the state’s generous credits unnecessary.

“The Inflation Reduction Act, and more specifically the extension of the 30% tax credit for both non-residential and residential solar projects, is directly relevant to the modeling of a successor net energy metering tariff in this proceeding,” Pacific Gas and Electric, Southern California Edison and San Diego Gas & Electric said in their Aug. 19 joint filing, which asked the CPUC to take official notice of the new law.

The federal credit “reduces the cost of solar adoption, thereby reducing the payback period for customers benefitting from the tax credit,” the IOUs said.

The utilities have pushed to reduce the longtime state credits that reimburse residential and non-residential solar owners for energy exported to the grid. Customers receive credits at full retail rates, which are now much higher than utility solar costs.

The utilities argued the scheme shifts $4 billion in costs from those who cannot afford rooftop solar to those who can.

In her December proposed decision, Administrative Law Judge Kelly Hymes agreed with the argument, saying the cost shift “disproportionately harms low-income ratepayers.”

Opponents of that proposal, however, contend that more than 1.3 million rooftops in California now have solar arrays, thanks in large part to the generous NEM credits. On Thursday, commenters took issue with the IOUs’ suggestion that the IRA made California’s incentives less necessary.

The state wants to reduce incentives just when Congress clearly indicated the importance of rooftop solar to the nation and when incentives are needed more than ever, they said.

“Your mindset of allowing new solar taxes to be charged and lowering the solar production credits is just wrong,” David Delphos of Orange County told the CPUC. “There is nothing in the new Inflation Reduction Act of 2022 that can justify any new California solar taxes or justify lowering the solar credits for solar system owners.”

Yvette DiCarlo of San Francisco said that “PG&E is now using the Inflation Reduction Act to further justify penalizing rooftop solar.

“Meanwhile PG&E’s website boasts how they own and operate 13 solar large farms in the Central Valley, far from their main customers, and how they also continue to add solar to the grid through contracts with third-party developers. They also boast adding 3,300 MW of new storage by 2024, so it’s clear that PG&E treats rooftop solar as a competitive threat to be squashed.”

MISO Flags Capacity Gap Risks in Fleet Transition Assessment

CARMEL, Ind. — MISO this week said its future holds exponential renewable growth, free-falling carbon emissions and a stubbornly persistent capacity risk, requiring a slew of new capacity.

The pronouncements come from the initial findings of MISO’s annual Regional Resource Assessment (RRA). The grid operator said that by using publicly available utility plans and its own assumptions, it expects the system will draw 30% of its annual energy from renewables by 2027 and approach 60% by 2041.

Also by 2041, the footprint will collectively decarbonize 80% from peak 2005 levels, MISO predicted. Renewables currently make up about 13% of the RTO’s resource portfolio.

“That is significant because this study is basically bringing together our members’ plans … and showing what the footprint will look like,” MISO engineer Aditya Jayam Prabhakar said during a Resource Adequacy Subcommittee meeting Wednesday.

Jayam Prabhakar said the risk of a capacity shortfall will persist throughout the fleet transition, “highlighting the immediate importance of coordinated resource planning.”

The grid operator said it found a need for members to expand nameplate capacity by 100 GW by 2030 to meet their combined carbon-reduction plans and stay within safe reserve margins. By 2041, MISO may need a 200-GW expansion in nameplate capacity.

The RTO also said it expects average capacity factors for operational natural gas and coal units to decline between 10 and 30% over the next 20 years. It said that even if current company resource planning is implemented on time, a systemwide shortfall is possible beginning in 2027.

Jayam Prabhakar added that the assessment relies on “highly evolving” information and characterized MISO’s analysis as a “guided tour,” as opposed to a deep exploration of future possibilities.

MISO did not include generation retirements beyond what is already publicly announced. Michelle Bloodworth, of coal lobby group America’s Power, said she thought the RTO was underestimating thermal generation retirements.

“Like all studies, the results of the RRA are sensitive to inputs and assumptions. This is but one possible scenario in a quickly evolving landscape,” Policy Studies Engineer Hilary Brown said.

She said MISO is notably missing some intermediate resource planning information from members around their 2030 greenhouse gas emissions goals. “Many companies have defined carbon-reduction milestones around 2030, leading to a possible large, single-year buildout.”

Responding to stakeholders’ questions, Brown said MISO has not yet included the torrent of renewable energy development that will possibly take place under the recently signed Inflation Reduction Act. She said the impacts under the law will be contemplated in next year’s assessment.

“We’re going to see some pretty crazy changes next year in how companies react to the Inflation Reduction Act,” Southern Renewable Energy Association Executive Director Simon Mahan said.

Brown said a “one-for-one capacity replacement” is not sufficient when replacing thermal generation with intermittents. She said that while MISO foresees a deepening capacity shortfall, members’ plans could change in reaction to MISO’s Planning Resource Auctions (PRAs).

“This isn’t new. We’ve seen it in last year’s PRA,” Brown said of declining and inadequate margins. (See OMS RA Summit Confronts Midwestern Supply Squeeze.)

Months after MISO’s capacity auction shortfall, several utilities unveiled deferrals on coal retirements.

WEC Energy Group and Alliant Energy have announced they are postponing retirement plans for multiple coal plants because of concerns over grid reliability. Likewise, Ameren Missouri is expected to defer the planned Sept. 1 retirement of its 1.2-GW Rush Island power plant until 2025. Two Montana Public Service Commissioners recently called on state lawmakers to do everything in their power to keep the Colstrip generating facility operating to prevent freezing deaths this winter. Colstrip is owned by Talen Montana, Puget Sound Energy, Portland General Electric, Avista, PacifiCorp and NorthWestern Energy.

On the other end of the spectrum, Clean Grid Alliance in mid-August saluted Illinois, Iowa and Indiana in particular as jurisdictions in the MISO footprint where renewable energy development is blossoming.

The alliance said Indiana’s 6.3 GW of solar projects in development currently ranks third in the nation; Illinois’ nearly 8 GW of operating wind, solar and storage capacity currently ranks sixth; and Iowa leads with 207 MW of land-based wind power coming online in the second quarter of 2022.

CGA said the nine states in MISO’s Midwestern region combined have 12 GW of clean power capacity in advanced stages of development.

Multiple stakeholders said MISO did not reveal enough about its modeling methods and data sources for others to fact-check its resource analysis.

The RTO plans to publish the full 2022 RRA in November.

Stakeholders Ask MISO for Midyear Capacity Accreditation

Disappearing reserves in its capacity auction has sparked a new stakeholder proposal at MISO.

MidAmerican Energy’s Dennis Kimm asked that MISO accredit new planning resources that enter the picture after the planning year is underway.

MISO doesn’t currently permit new generation to convert its output into accredited capacity in the middle of a planning year. New generators currently must wait until preparation for next year’s capacity auction begins before they become eligible to receive zonal resource credits.

Several stakeholders said they supported the proposal and requested MISO create new tariff language immediately.

Alliant’s James Niccolls said that, “frankly, it’s hard to explain” MISO’s current practice to his company’s leadership and customers.

“There’s obviously widespread stakeholder support on this,” RASC Chair Kari Hassler said.

Meanwhile, stakeholders again requested that MISO publish more data ahead of its PRAs on generator suspensions and granted participation exclusions. Some have said MISO should publish a line item on generation that’s likely to be unavailable in the auction and give members a better idea of the footprint’s expected margins before the auction window opens.

California Adopts Rule Banning Gas-powered Car Sales in 2035

The California Air Resources Board on Thursday adopted regulations that will require all new cars sold in the state to be zero-emission or plug-in hybrid by 2035 — a move the agency described as historic and trailblazing.

The CARB board voted unanimously to approve the regulations, called Advanced Clean Cars II (ACC II).

“This is the most important and most transformative action that CARB has ever taken,” board member Daniel Sperling said. Sperling, who is a founding director of the Institute of Transportation Studies at the University of California, Davis, cast his vote by saying “super aye.”

“We can solve this climate crisis if we focus on the big, bold steps necessary to cut pollution. California now has a groundbreaking, world-leading plan to achieve 100 percent zero-emission vehicle sales by 2035,” Gov. Gavin Newsom said in a statement.

ACC II will require car manufacturers to provide for sale in California an increasing percentage of zero-emission vehicles each year. The new regulation starts with a 35% zero-emission vehicle (ZEV) sales requirement for model year 2026, increasing to 68% in 2030 and reaching 100% in 2035.

The rules build on the state’s Advanced Clean Cars regulation, which was first adopted in 2012 and is still in effect. The current regulation’s ZEV sales requirement tops off at 22% for model year 2025.

In addition to ZEV requirements, the ACC II regulation includes a low-emission vehicle (LEV) component aimed at reducing tailpipe emissions of gasoline-powered cars.

Seventeen states have adopted California’s Advanced Clean Car standards as allowed under Section 177 of the Clean Air Act. Many of those states are now expected to consider adoption of ACC II.

CARB must apply for and receive a waiver from the EPA to enforce the regulations.

Reducing GHG

Transportation is California’s single largest source of greenhouse gas emissions and air pollution, according to CARB. ACC II is expected to reduce passenger vehicle GHG emissions by 50% or more by 2040.

Environmental groups commended CARB for adopting ACC II.

“The standards passed today move California to the head of the pack in the race for clean transportation,” Fred Krupp, president of Environmental Defense Fund, said in a statement. “Thanks to the state’s leadership, California — and our entire country — are now speeding toward a safer and healthier future with no tailpipe pollution.”

But some people who commented during the board meeting were concerned about the impact of the ZEV requirements on small businesses and farmers. One farmer asked CARB staff how she is supposed to install a Tesla charging station in the middle of her cornfield.

ACC II applies to new vehicle sales and will not impact vehicles already on the road.

One speaker at the board meeting predicted that as a result of the regulation, drivers will hang on to their internal-combustion engine vehicles longer, bringing in more business for mechanics.

Infrastructure Is Key

CARB board member Barbara Riordan cautioned that building sufficient EV charging infrastructure will be key to the success of the program.

While substantial funding has been earmarked for EV infrastructure, “it has to be implemented,” Riordan said.

“A lot of people won’t invest in an electric vehicle unless they can be assured that the infrastructure is there to keep it charged, to keep it going,” she said.

The ZEV sales requirements of ACC II apply to cars, pickup trucks and SUVs. Plug-in hybrid (PHEVs), full battery-electric and hydrogen fuel cell vehicles count toward an automaker’s requirement. PHEVs must have an all-electric range of at least 50 miles under real-world driving conditions. Automakers will be able to meet up to 20% of their ZEV requirement with PHEVs.

Battery-electric and fuel cell vehicles will need a minimum range of 150 miles to qualify under the program. In addition, they must include fast-charging ability, come with a charging cord and meet new warranty and durability requirements.

Western Power Pool Board Approves WRAP Tariff

The Western Power Pool’s board on Tuesday approved a tariff to implement its Western Resource Adequacy Program, an initiative intended to ensure that participants across much of the Western Interconnection have sufficient capacity amid a changing resource mix.

WPP said it is planning to file the WRAP tariff with FERC by Aug. 31, followed by a 30-day comment period.

The program, which already has 26 participants in an area reaching from British Columbia to Arizona and east to South Dakota, is the “first region-wide reliability planning and compliance program in the history of the West,” WPP said in a news release Wednesday.

The tariff approval “is another major milestone leading us closer to making this first-of-its-kind program a reality,” WPP CEO Sarah Edmonds said in the news release. “Resource adequacy is an urgent and immediate challenge, especially in the West, and requires this type of regionwide approach to address it.”

Last week the WRAP’s Resource Adequacy Participant Committee (RAPC), consisting of a representative from each participant, also approved the draft tariff. The 74-page document lays out the program’s governance structure, including the roles of the RAPC, a Committee of State Representatives (COSR) and a Program Review Committee.

It describes in detail the program’s two main “time horizons,” a forward-showing program requiring participants to show they have sufficient capacity months in advance of summer and winter peaks, and an operational program, focused on the allocation of resources in real-time and day-ahead time frames.

And it addresses issues such as participation rates, financial penalties for resource deficiencies and failures to deliver, and dispute resolution.

Since 2020, WPP has been developing the WRAP, an initiative conceived to address concerns that Northwest utilities have been increasingly and unknowingly drawing on the same shrinking pool of reliability resources. But interest in the effort spread quickly to other areas of the West. In a move that signified its expanding reach across the Western Interconnection, the Northwest Power Pool rebranded itself as the Western Power Pool earlier this year.

The WPP is slated to launch a “nonbinding” iteration of the WRAP in the third quarter of this year and a binding phase with penalties sometime in 2024. Initially, the absence of enforcement and penalties will shield the program from FERC oversight, giving members additional time to iron out wrinkles and finalize its design.

WPP last year selected SPP to develop and operate the technical aspects of the WRAP, providing the market’s forward-showing functions, modeling and system analytics, and real-time operations.

Some in the West have speculated the WRAP could serve as a springboard for the eventual development of an RTO, one that would compete with CAISO’s stalled regionalization efforts and the ISO’s well-established Western Energy Imbalance Market. SPP has been using its new foothold in the West through the WRAP to build interest in its Markets+ program, a collection of services that stops short of a full RTO but could eventually develop into one. (See SPP Continues to Build on Markets+ Offering.)

Anticipating possible future requirements, WPP has already moved to restructure its governance and prepare to adopt some elements of an RTO, such as the appointment of an independent board of directors. WPP also established the COSR to ensure that utility regulators have a voice in discussions related to the WRAP.

The tariff appears to address the eventuality, saying: “Subject to the limitations and prohibitions imposed under Section 3.4 of this tariff, if the Board of Directors votes to file at FERC to expand the WRAP to include market optimization or transmission planning services, WPP will initiate a formal process with COSR and other stakeholders to conduct a full review of governance structures and procedures, including the role of states.”

‘Collaboration and Transparency’

The WPP published the WRAP draft tariff last month, inviting stakeholders to comment during a public webinar on July 25. Feedback from that session was incorporated into the updated draft that the board approved.

“Throughout this process we have remained committed to collaboration and transparency,” Edmonds said. “For three years, we have worked with regulators, participants and stakeholders to shape the program. We’ve listened to stakeholder voices, embraced their comments, and refined the program design and the tariff itself to get to a solution supported by all participants.”

FERC’s approval of the tariff would allow WPP to set rates and terms of participation and to make governance changes.

“WPP is hoping for a final order from FERC giving approval by the end of this year,” the group said in the news release. “The WRAP team also intends to confirm commitments from potential participants for the next phase of their participation by mid-December.”

WRAP Stage 1 participants include Arizona Public Service, Avangrid, Avista, Black Hills Energy, Basin Electric Power Cooperative, Bonneville Power Administration, Calpine, Chelan PUD, Clatskanie PUD, Douglas PUD, Eugene Water and Electric Board, Grant PUD, Idaho Power, NorthWestern Energy, NV Energy, PacifiCorp, Portland General Electric, Powerex, Puget Sound Energy, Seattle City Light, Snohomish PUD, Shell Energy, Salt River Project, Tacoma Power, Turlock Irrigation District and The Energy Authority, which is representing seven Washington and Oregon publicly owned utilities.
