New IBR Standard to Finally Go to Ballot

NERC’s proposed standard setting generator ride-through requirements for inverter-based resources will soon go out for a formal ballot round the ERO hopes will finally see it gain the required support from industry, members of the Standards Committee heard in their meeting Sept. 18 in Waukesha, Wis. 

Committee Chair Todd Bennett, of Associated Electric Cooperative, told members the revised PRC-029-1 (Frequency and voltage ride-through requirements for IBRs) had been out for public comment since the previous week, having been posted after the technical conference hosted by NERC on Sept. 5. (See NERC, Industry Discuss IBR Issues in Technical Conference.) The formal ballot round will begin Sept. 24 and end Sept. 30. 

Bennett said the conference “was received rather well” by ERO stakeholders, complimenting NERC staff for their fast work setting up the event on short notice. NERC’s Board of Trustees ordered the committee to hold the conference last month, invoking its special authority to bypass the normal standards development process for the first time to meet FERC’s November deadline for submitting ride-through standards. (See “Board Invokes Standards Authority to Meet IBR Deadline,” NERC Board of Trustees/MRC Briefs: Aug. 15, 2024.) 

During the two-day conference, NERC staff presented on the background of the standard, while industry stakeholders took part in panels discussing their issues with the proposed standard and possible ways to address them. Amy Casuscelli of Xcel Energy said “it was really helpful to get to hear the technical experts in the room … weigh in on their different perspectives and different views.” 

Casuscelli also praised the inclusion of original equipment manufacturers (OEMs) who could address the manufacturing challenges that might be posed by some requirements of the proposed standard. Trustee Sue Kelly, the board’s liaison to the Standards Committee, agreed that this community was a valuable addition to the conference. 

“I thought it was very powerful to have everybody all in the same room at the same time. The drafting team reps were able to say, ‘This is why we wrote what we wrote’; the OEMs … who are going to be crucially important to implementing anything were there to tell us what they thought they could and could not do; and we, in turn, were able to say to them, ‘Your equipment is becoming increasingly important, and you bear some responsibility in this as well,’” Kelly said. 

Standards Actions Approved

The committee approved a handful of standards actions at the meeting, starting with a proposal to appoint supplemental members to the standard drafting team (SDT) for Project 2020-06 (Verifications of models and data for generators). 

The project was recently assigned to satisfy Milestone 3 of FERC’s Order 901, which requires the ERO to submit standards addressing validation and verification of models for inverter-based resources by November 2025. 

NERC Manager of Standards Development Jamie Calderon told members the ERO is seeking to supplement the SDT to provide “the requisite experience to tackle” the added responsibilities of Order 901. The ERO solicited nominations from the industry and received nine; seven were recommended to the committee for approval. As usual, the candidates were not identified during the meeting except by number. 

Calderon said one of the remaining nominees “did not respond to interview requests, and recommendations were not received from their references”; the other informed NERC that they would prefer to join a different SDT. As a result, neither was recommended for approval. 

The seven nominees were approved unanimously, although Robert Blohm of Keen Resources moved to add the second of the unrecommended nominees to the slate. He argued that four of the seven recommended candidates had Canadian backgrounds and adding so much Canadian representation to the team could make it regionally unbalanced. However, Blohm’s motion did not receive a second and did not advance. 

Members also approved the addition of a single new candidate to the SDT for Project 2023-09 (Risk management for third-party cloud services). The committee approved the SDT’s current slate at its July meeting, but since that time, one of the members has stepped down because of workload concerns. They will be replaced by a candidate who was recommended by NERC staff at the July meeting but replaced with a different nominee by the committee. 

Margo Caley of ISO-NE explained that both nominees are from the same sector, meaning there will be no change in sector representation on the SDT. 

Finally, the committee authorized the posting of proposed reliability standard TOP-003-7 (Transmission operator and balancing authority data and information specification and collection) for a 45-day formal comment period, with ballot pools formed in the first 30 days and ballots conducted during the last 10 days. 

TOP-003-7 (on page 14 of the agenda) was developed by the SDT for Project 2022-03 (Energy assurance with energy-constrained resources). The revisions to the existing standard will add near-term energy reliability assessment to the list of functions for which balancing authorities must provide data to entities that request it.

Comments on Western RO Stakeholder Plan Show Complexity of Effort

Recent stakeholder comments filed with the West-Wide Governance Pathways Initiative illustrate — once again — the complexity of building the new kind of Western “regional organization” (RO) envisioned by backers of the effort.

The comments came in response to Pathways’ draft plan for the RO’s stakeholder process, an aspect of the organization likely to be as important as its governance structure in swaying some Western electricity sector participants to choose CAISO’s Extended Day-Ahead Market (EDAM) over SPP’s Markets+.

The Pathways Launch Committee floated the plan during an Aug. 28 workshop, the last of four such intensive workshops facilitated by consulting firm Gridworks to hash out ideas about how the RO would engage with its stakeholders and how the stakeholder process would tie into governance. (See No Clear Blueprint for Western ‘RO’ Stakeholder Process.)

At the heart of the proposal is the formation of a Stakeholder Representatives Committee (SRC), described as the “primary stakeholder body that works with RO staff to catalog and prioritize initiatives, as well as to define initiative problem statements and solutions.”

During an Aug. 28 workshop to discuss the RO’s stakeholder process, Launch Committee Co-Chair Pam Sporborg, director of transmission and market services at Portland General Electric, described the SRC as an evolution of the Western Energy Imbalance Market’s (WEIM) Regional Issues Forum, which itself has evolved over time into a key stakeholder body for addressing issues related to that market.

The proposal calls for the SRC to be a sector-based body, with sectors to be “self-organized” and committee representatives selected by members of each sector.

“Sectors may elect to use selection criteria to establish diversity among SRC representatives that may be important to the sector,” a presentation accompanying the proposal states.

The proposal defines nine sectors to be represented on the SRC, including:

    • EDAM entities (one seat);
    • WEIM entities (two seats);
    • CAISO participating transmission owners (2);
    • transmission-dependent utilities (3), including one seat reserved for community choice aggregators;
    • public interest organizations (PIOs) (1);
    • consumer advocates (1);
    • large commercial and industrial consumers (1);
    • independent power producers, independent transmission developers and marketers (3), with assurance that IPPs and marketers each have an opportunity for a seat to represent different business models; and
    • distributed energy resources (1).

One seat would be reserved for federal power marketing administrations (PMAs) in either the EDAM or WEIM sectors — if any such agency participates in those markets.

According to the proposal, every organization registered to vote in the RO would have the chance to specify their support, opposition or neutrality when the SRC votes on an issue. To be eligible to vote, an organization must register in a specific sector and agree to a code of conduct.

“Once the organizational votes are tallied, the nine sectors of the SRC will also vote, with the threshold for support, opposition or neutrality determined by the organizations in the sector,” the proposal says. “The SRC representative will report on any specific splits that have been established by that sector, consistent with the self-organizing principle described above. The results of all votes will be provided in the materials related to the issue.”

The plan also puts stakeholder initiatives into three categories, including:

    • compliance/nondiscretionary, such as responses to FERC rulemakings or fixes to market design flaws that require tariff changes;
    • compliance with state and local public policy, which could require stakeholder discussion to determine whether a tariff change is needed; and
    • discretionary initiatives that can be advanced by any stakeholder, the states committee, market monitor, “independent market adviser” or RO staff.

Once initiatives are categorized, the stakeholder process would entail prioritizing them through a “roadmap” process. That would be followed by an “issue evaluation” to determine the nature of the problem to be solved (stage 1) and an “identification of solutions” (stage 2). The last step would be seeking approval by the RO board.

Dilution Concern

The Pathways Launch Committee received 22 comments on the proposal, including one combining responses from seven PIOs.

Other commenters included utilities (some jointly filing), large energy consumers, industry interest groups, an energy trader, the Bonneville Power Administration and Google.

In its comments, Black Hills Power expressed concern that the SRC “does not provide sufficient representation to utilities, which play a critical role in ensuring grid reliability and managing market operations.”

The South Dakota-based utility is one of two Black Hills Energy subsidiaries that last month said it would pull out of SPP’s Western Energy Imbalance Service and join CAISO’s Western Energy Imbalance Market, although it made no commitment to EDAM. (See CAISO’s WEIM Plucks Black Hills Utilities from SPP’s WEIS.)

“We recognize that all registered utilities within a sector, including utilities, can vote and contribute to the sector’s overall vote,” Black Hills wrote. “However, we still have concerns that utilities’ votes will be diluted within sectors where there are diverse participants.”

Black Hills recommended that Pathways ensure that utilities have “a formal mechanism for ensuring that their interests are not overshadowed by other entities within the sector.” It proposed a “more tailored sector designation for utilities” with “clear distinctions” among the types of utilities — such as investor-owned or publicly run — “to ensure that their unique perspectives are not lost within larger, more diverse sectors.”

NV Energy, which has already committed to joining the EDAM, said it supported the use of a sector-based process only for selection of the RO board and development of the annual roadmap to prioritize RO initiatives.

“While recognizing potential benefits of indicative votes, NV Energy does not believe the sector-based process proposed in the draft discussion paper is the best approach,” the utility wrote.

Instead, NV Energy “strongly supports” the indicative voting approach CAISO used in the recent stakeholder process for Pathways Step 1 — which granted the Western Energy Markets (WEM) Governing Body “primary” authority over matters related to the WEIM and EDAM. (See CAISO, WEM Boards Approve Pathways ‘Step 1’ Plan.)

In that situation, the utility noted, the ISO “simply added a voting request to the stakeholder comment template asking if the participant supports, opposes or was neutral to the proposal. The votes were then tabulated and presented to the WEM Governing Body and the CAISO Board of Governors to assist in their deliberations.”

NV Energy said that approach “provides far greater transparency” because it:

    • records and presents each specific vote, preventing intra-sector disagreements over an initiative from being concealed by the sector’s majority vote;
    • “better represents minority interests and reduces a feeling of disenfranchisement” among entities holding a minority position within a sector; and
    • “reduces the burdensome and time-consuming process for separate sector-led votes.”

The utility also recommended a second seat for EDAM entities and questioned the need for three seats for transmission-dependent utilities.

“Presumably, these are transmission-dependent utilities within the EIM/EDAM footprint,” the utility wrote. “If one seat is for a transmission-dependent utility within California and one for a transmission-dependent utility outside of California, it may be understandable but does seem to create a mismatch with the three seats being allotted to the total of EIM and EDAM entities.”

‘Ambiguities’ or ‘Right Balance’

Salt River Project (SRP) said it “generally supports” creation of a “parent committee,” such as the SRC, “through which issues flow both up to the regional organization board and down to working groups.”

“This structure ensures that topics are defined at a high level based on stakeholder input before being remanded down to the working groups/task forces,” it wrote.

But SRP also recommended changing the proposed composition of the SRC to match that of the Western Resource Adequacy Program’s Nominating Committee, which consists of representatives from investor-owned utilities (2), consumer-owned utilities (2), retail competition load-responsible entities (1), PMAs (1), independent power producers/marketers (1), PIOs (1), retail customer advocacy groups (1), industrial customer advocacy groups (1) and one “independent sector” representative for entities that don’t fit into any other category.

SRP also agreed with the proposal that RO staff should take on most of the “burden” of facilitating and administering the stakeholder process, saying the arrangement would allow stakeholders to participate “nimbly” regardless of their staffing levels.

Google offered no comment on the list of proposed SRC sectors but recommended that each sector develop a manual of board-approved bylaws to define who could be a member of the sector, frequency of meetings, how it develops consensus and how it communicates its positions to the RO’s committees, staff and board.

“This structure would mirror MISO’s, where sectors are self-organizing but each sector’s bylaws are approved by the board,” the company wrote.

BPA requested that one additional seat be reserved for PMAs in either the WEIM or EDAM sector, assuming a PMA is a member of either. In the case of no PMA participation in either market, the agency asked that an additional seat be reserved for PMAs in the transmission-dependent utilities sector given that their transmission would still be used to deliver to load in the CAISO-run markets.

BPA said it supports the concept of a category for state and local public policy stakeholder initiatives, but it also wants federal obligations that may be statutory requirements for itself and the Western Area Power Administration to be added to the category.

“In implementing the process, it will be important to ensure that these initiatives only skip Stage 1 in situations where the problem statement has broad agreement or is so clearly defined by the state policy initiative that there is no room for discussion,” BPA wrote.

The California Large Energy Consumers Association (CLECA) commented on “the imbalance between buyers and sellers in SRC voting sector definitions and encourages efforts to establish commensurate supply and demand representation.” CLECA called for the Launch Committee to address the “imbalance” by providing each sector with two seats or, alternatively, just one seat or one seat with one backup.

“All sectors have heterogeneous membership worthy of adequate representation at the SRC. This revision partially restores the balance between supply and demand representation,” CLECA wrote.

The Portland-based Public Power Council (PPC), which represents consumer-owned utilities in the Northwest, raised concerns about “the ambiguities in the RO/CAISO relationship based on the current proposal,” saying the role of both the ISO staff and board is unclear.

“Also, it is unclear whether pursuing an RO stakeholder process as outlined in the discussion document would have any impacts on the existing CAISO stakeholder process and whether those processes would be kept distinctly separate, or whether there would be some combined discussions or efforts between the RO and CAISO. We would appreciate the Launch Committee addressing these issues in the Step 2 proposal,” the PPC wrote.

The seven PIOs — which include the Northwest Energy Coalition, Western Resource Advocates, Natural Resources Defense Council and Environmental Defense Fund, among others — said the SRC “strikes the right balance between clear roles for each sector representative while allowing all interested stakeholders to participate in the process.”

The PIOs expressed support for the lack of fees or other monetary requirements for participating in the RO’s stakeholder process.

“This is an important aspect to ensure equal access for all stakeholders; if the regional organization were to require a fee for participating in the stakeholder process, that fee can be a barrier to smaller organizations that, because of competing priorities, may be unable to spend scarce resources on participation fees, and thus will be unable to have a full and equal voice, via voting or committee membership, in the process,” they wrote.

Report Finds Mass. Storage Programs Falling Short on Equity

While Massachusetts has some of the strongest incentives for storage resources in the country, its programs are lagging in their focus on equity and environmental justice, according to a new report commissioned by the Clean Energy Group.  

The report analyzed the equity provisions in three Massachusetts programs that incentivize storage resources: the Clean Peak Energy Standard, the ConnectedSolutions program and the Solar Massachusetts Renewable Target (SMART) program. 

The report found that “the current energy storage-incentivizing programs in Massachusetts, while they are groundbreaking in many ways, do not live up to the commonwealth’s clean energy equity commitments.” 

It noted that the ConnectedSolutions program, which is part of the state’s utility-run energy efficiency program, and the Clean Peak Energy Standard lack incentives for deploying storage in low-income households or environmental justice neighborhoods and also do not include reporting requirements regarding equity.  

The SMART program, which focuses on boosting solar resources but also includes an incentive for co-located storage, does include additional incentives for low-income customers. However, data from the program indicate just 1.4% of SMART storage projects used this low-income adder. 

Todd Olinsky-Paul, senior project director at the Clean Energy Group, said he was surprised to find that not only is there no equity requirement, there’s no reporting requirement for two of the three programs. 

He emphasized the importance of including low-income households in the early stages of storage deployment and said low-income households often experience the most significant benefits of behind-the-meter storage resources.  

As climate change drives increased threats from extreme weather to the grid, the underserved communities are “getting hit the hardest,” Olinsky-Paul said.  

Because low-income households typically are the hardest to reach when deploying new technologies, it makes sense to prioritize these groups from the outset, Olinsky-Paul said. “Once you figure that out, then you’ll know how to get it to everybody else,” he added. 

The report is intended to influence the state’s ongoing work to update each of the programs, Olinsky-Paul noted. 

Commissioner Elizabeth Mahony of the Massachusetts Department of Energy Resources (DOER) told NetZero Insider the state plans to include an increased focus on equity in all three programs. 

“We’re in the infancy — or maybe toddler years — of the storage industry, and so our programs that work with storage deployment are in a similar phase,” Mahony said.  

The state issued a straw proposal in July for its update to the SMART program and proposed to increase the eligibility of low-income customers and require that community-shared solar programs enroll at least 40% low-income customers. 

The state also is working with the electric distribution companies (EDCs) to finalize their energy efficiency plans for the 2025/27 period, which will include updates to ConnectedSolutions. 

Regarding the Clean Peak standard, Mahony said the state is finishing updates focused on ratepayer protection and plans to address equity “in the next phase of that program.” 

Mahony noted that the state updated the Clean Peak standard in July to add “a near-term multiplier so that projects that are ready to go and can interconnect by 2027 … will get additional funding.” 

The DOER commissioner added that Gov. Maura Healey’s recently proposed closeout supplemental budget would direct a procurement of up to 5,000 MW. (See Mass. Gov. Healey Includes Permitting Reform in Budget Proposal.) The supplemental budget proposal also includes major reforms to the state’s permitting and siting processes, which Mahony called “our top topic.”

She said the state also is preparing a new $50 million storage grant program “that we hope to launch in some form later this year.” 

The legislature in 2018 established a goal for the state to deploy 1,000 MWh of energy storage by the end of 2025. In February, electric utilities reported the state has reached 569 MWh of installed storage, with 8,806 MWh in the development pipeline.

New Western Tx Could Bring Big CO2 Benefits, Study Shows

Carbon dioxide emissions from the Western U.S. power sector could drop by 73% from 2005 levels if 12 transmission projects in the development pipeline are finished by 2030, according to a new study from the U.S. Department of Energy.  

The report’s model incorporates 12 future transmission projects, which collectively span about 3,000 miles, and the likely wind and solar power projects and battery storage systems that would take advantage of the new capacity. The scenario “shows a reduction of CO2 emissions by 73% relative to 2005, reaching to 27% CO2 emissions in 2030,” according to the report published by the DOE’s Pacific Northwest National Laboratory on Sept. 13. 

“This work is important because it shows that significant progress can be made [toward] decarbonization policy objectives if we proceed with already-planned transmission projects to meet new capacity needs with new renewable resources,” Nader Samaan, report co-author and chief power systems research engineer at PNNL, told RTO Insider in an email. 

The report said more transmission could lead to renewable energy replacing some large thermal fossil generation, with the highest emissions reductions occurring in Utah, Nevada, Wyoming, Colorado, Arizona and New Mexico. 

“As of July 2024, the Western Interconnection hosts 30 gigawatts of wind power, 38 GW of solar power and 14 GW of energy storage,” the study said. “The report’s scenario would add an additional 35 GW of wind, 31 GW of solar and 12 GW of energy storage by 2030.” 

The 12 transmission projects behind the model include the 500-kV Boardman-to-Hemingway line, the Gateway West project and the Southwest Intertie Project-North, among others. (See DOE Awards $371M to Regulators, Communities Grappling with New Tx.) 

Aside from the purported environmental advantages, the transmission projects could also decrease generation costs by 32% compared with a reference case in which the projects were not built. However, “capital costs for generation and transmission are not considered as part of this analysis and would be needed for a complete economic evaluation,” according to the report. 

“Most of the infrastructure upgrades selected are either in interconnection queues or the transmission planning pipeline, increasing the likelihood that they will be realized,” the report stated. “In other words, the projects selected in this analysis rely implicitly on some economic analysis conducted by those proposing the projects.” 

The model also predicts a 26% reduction in California’s annual net energy imports from the Northwest. Under the scenario, the state could tap into “newly integrated wind resources from areas with abundant wind, such as Wyoming and New Mexico,” according to the report. This would also provide congestion relief for the Northwest, the report added. 

The report is part of the DOE-funded National Transmission Planning Study, slated to come out this year. 

“The upcoming National Transmission Planning study will expand on the possible transmission buildouts that could help the nation reach higher decarbonization goals,” Samaan said.

MIT Report Proposes Policies to Grow Use of Advanced Transmission Technologies

Advanced transmission technologies (ATTs) can help utilities meet the rising levels of demand that are stressing the grid, according to a report released Sept. 17 by the Massachusetts Institute of Technology’s Center for Energy and Environmental Policy Research (CEEPR).

ATTs are a suite of technologies that include grid-enhancing technologies (GETs). The most widely used ones are dynamic line ratings, advanced power flow control devices, topology optimization and high-performance conductors.

“Increased use of advanced transmission technologies can play a major role in meeting this demand growth quickly and cost-effectively,” the report says. “However, electricity market structures — which disincentivize investment in innovation — are impeding progress towards modernizing the electric grid.”

“A Roadmap for Advanced Transmission Technology Adoption” was written by Grid Strategies President Rob Gramlich, along with CEEPR Fellow Brian Deese and Research Associate Anna Pasnau, both of whom previously worked at the White House for President Joe Biden.

The technologies have been used for decades and are more widely deployed abroad. In the U.S., the lack of incentives for transmission providers, information provided to regulators and some features of electricity markets hold them back, according to the report. The profit structure of electricity markets does not offer the right incentives for transmission providers to adopt many forms of ATTs, despite their consumer benefits and the ability to quickly add transmission capacity to the grid, it says.

“Under the current electricity industry regulatory structure, utilities earn profits from capital expenditures, meaning that they are incentivized to make more costly capital investments (e.g., building a new power plant) over changing their operating expenses or lowering and smoothing demand for electricity — even when those capital expenditures ultimately increase costs for consumers,” the report says.

The “capex bias” is an accepted and well-known feature of cost-of-service regulation, according to the report. It disincentives utilities from deploying GETs because they would avoid the need to invest in new transmission — cutting their capital expenditures and thus their profits. Part of regulators’ job is to prevent utilities from taking advantage of that bias and ensure investments are in line with consumer interests, the report says.

“However, both transmission providers and regulators can struggle to identify the best way to expand capacity against a backdrop of multiple options, and for some technologies, they need new modeling practices to assess benefits,” the report says. “Transmission providers and their regulators have historically focused their cost-benefit analyses on a narrow set of risks and thus are slow to scale innovations, preferring the status quo.”

Some policies around ATTs have already improved, with states passing laws aimed at encouraging them, the report notes. Other policies have sought to align utility incentives with key performance metrics; FERC Order 1920 requires transmission providers to consider ATTs in the planning process.

Those steps are in the right direction, but the paper proposes five more to spread the use of ATTs across the grid:

    • Regulators should require the use of ATTs in certain contexts, with the paper suggesting FERC require DLRs on highly congested lines to increase their capacity at one-tenth the cost of reconductoring. The Department of Energy should adopt a national conductor efficiency standard, which would ensure utilities use more efficient lines that can cut line losses by 30%.
    • Transmission providers and regulators should have to conduct robust analyses of the value of ATTs for the electric grid. Order 1920 requires they be considered, but it lacks specificity on how robust of an analysis will be required. The paper suggests states adopt laws requiring more stringent analyses to complement the FERC rule.
    • FERC should create financial incentives for transmission providers to adopt ATTs where they provide high benefits. The commission should adopt a shared-savings incentive nationally, giving utilities a cut of ratepayer savings from GETs adoption, and where possible state legislators should authorize additional returns on equity for ATT investments.
    • The commission should require transmission providers to share additional information publicly so third parties can evaluate ATT adoption and hold utilities accountable when they fail to make sensible investments.
    • FERC should open up the planning process for a third party to work on deploying ATTs. The paper suggests the commission could require transmission providers to release relevant data to the National Renewable Energy Laboratory, or another qualified nonprofit entity, to come up with plans for each grid operator to adopt ATTs and update them on a regular basis.

MISO, Monitor at Stalemate over Need for $21B Long-range Tx Plan

INDIANAPOLIS — MISO’s quarterly public meetup with its board of directors put on display the unrelenting rift between the RTO’s planners and the Independent Market Monitor over MISO’s $21 billion in upcoming long-range transmission planning.  

At a Sept. 17 Markets Committee meeting of the MISO Board of Directors, MISO IMM David Patton encouraged a recess on the proposed $21 billion second long-range transmission plan (LRTP) portfolio until MISO agrees to rework its 20-year view of its system and the benefit estimation of the transmission.  

Patton repeated concerns he raised earlier at a stakeholder workshop on MISO’s second LRTP portfolio, which MISO hopes to advance for board approval by the end of 2024. (See MISO Says 2nd Long-range Tx Plan to Cost $21B, Deliver Double in Benefits.) 

“We should pause this process and get to the bottom of this before we allow it to move on,” Patton told board members. “The problem is we don’t have a credible, ‘what-will-the-world-look-like’ scenario if we don’t build this transmission.”  

Senior Vice President of Planning and Operations Jennifer Curran said MISO believes it has devised a valuable portfolio and stands by its conservative, 1.9:1 benefit-to-cost estimate.  

“I think we have a different philosophy on benefits that leads to a fundamental disagreement,” she told the board.  

“We can’t perfectly predict the future. But through the use of scenarios, we can develop the most robust portfolio using the modeling we have available today,” Vice President of System Planning Aubrey Johnson said.  

Johnson said the LRTP can be interpreted as “skating to where the puck will be.” He said recent load growth shows MISO’s top-end, most radical planning scenario is likely, when some stakeholders thought it outlandish five years ago.  

Johnson said even scaling back MISO’s decarbonization benefit for areas of the footprint where the value of decarbonization isn’t openly acknowledged, the portfolio still would have 1.3:1 benefit-cost ratio.  

Multiple stakeholders urged MISO not to entertain the IMM’s request for an assumptions and benefits rework.  

ITC’s Brian Drumm said MISO leadership should reject the Monitor’s calls to “develop and test against an alternate reality” regarding LRTP transmission planning.  

Drumm said it’s “irresponsible and dangerous” for Patton to assume MISO won’t experience a major load shed event simply because it never has or assume members will make plans independently to dodge one.  

“Stakeholders have chosen to solve the reliability imperative through long-range planning and particularly” the second LRTP portfolio, Drumm argued. “The IMM’s request is inappropriate because MISO’s role is to plan regional transmission, not to serve as an integrated resource planner.”  

Drumm added that the industry is aware that significant loss of load events will occur again and become more pronounced by extreme weather. He said avoiding just one widespread load shedding event can more than cover the $21 billion price tag of LRTP II.  

The Union of Concerned Scientists’ Sam Gomberg said MISO isn’t going far enough in incorporating climate risk assessments in long-range transmission planning. He said the RTO should anticipate changing weather patterns to inform system planning so it doesn’t end up trying to solve the challenges of extreme weather on the fly in the control room.  

Gomberg also said MISO is correct to value decarbonization in transmission planning. He said Patton’s argument that federal production tax credits already fully value decarbonization and MISO’s benefit metric is redundant “borders on absurd” and gives too much credit to Congress to objectively put a price on the social cost of carbon.  

MISO Director Phyllis Currie asked if the RTO has a stance on planning for increased climate impacts on the system.   

“I think our primary objective is to reflect our members’ objectives. We really follow the lead of our members [rather] than taking an independent view of climate change,” Curran said. However, Curran added that from an operations standpoint, MISO uses analytics and machine learning to forecast weather events that historically haven’t occurred.   

“David Patton consistently misunderstands the benefits of regional backbone lines … [and] doesn’t like long-term scenario-based planning,” Sustainable FERC Project attorney Lauren Azar argued to board members. Azar said the IMM appears to want MISO to “go backwards” into the “balkanized system” that existed before the RTO’s creation.   

Azar rhetorically asked board members to place a monetary value on the 210 lives lost when the lights went out on Texas residents during Winter Storm Uri.  

Azar said the IMM should stick to its original purpose of “mainly markets” and advised MISO not to pay for the IMM’s opinions on transmission planning through its IMM budget.  

The MISO IMM has made some stakeholders uneasy with his interest in MISO’s long-range transmission planning and public criticism of the 20-year fleet and benefit estimates MISO uses. Since last year, some have said the IMM oversteps his role.  

MISO’s board of directors has included a $250,000 allowance in the Monitor’s $10 million budget next year to “monitor ratings and identify transmission withholding and compliance” associated with ambient adjusted line ratings requirements it will roll out under FERC Order 881. The line item and data collection of transmission data caused consternation among MISO transmission owners.  

MISO staff will be “actively discussing what data” transmission owners must provide, MISO Director Trip Doggett said.

DOE, PNNL Initiative to Focus on Equity in Tx Planning

Equity and community engagement have not been high priorities for the RTOs, ISOs, utilities and other organizations that have primary responsibility for planning the nation’s transmission system — a situation that historically has resulted in siting and permitting delays and, in some cases, yearslong litigation.

But the U.S. Department of Energy and Pacific Northwest National Laboratory (PNNL) want to change that narrative with a new initiative ― the Inclusive Transmission Planning (ITP) project ― which will provide technical assistance to grid planners seeking to integrate equity and community input into their projects up front, rather than as an add-on.

Speaking at a Sept. 17 webinar on the ITP, Emma Hibbard, a technical advisor in DOE’s Grid Deployment Office, laid out the rationale for the new program.

“Timely transmission deployment is essential to increase grid reliability and resilience and lower costs for consumers, as well as pave the way to a clean energy future, but often public acceptance of new transmission development can constrain [or] delay deployment,” Hibbard said. “There’s also an increasing awareness that positive outcomes for transmission development really hinge on ensuring positive and equitable outcomes for all, including disadvantaged and rural communities along transmission routes.”

Hibbard acknowledged that FERC, state regulators and many grid planners are working to improve transparency and public participation. But, she said, “there’s a need for more information and more support around energy equity and the relationship to transmission planning, and … new approaches to soliciting and integrating community input, in addition to what is already existing.”

The webinar provided an overview of the ITP program, which is offering two tracks of technical assistance — but no funding — for grid planning organizations.

“Tier 1 is really about education, outreach and capacity building,” said Paul Wetherbee, an advisor on regional energy system planning at PNNL. “We’re really talking about educating and building awareness of energy equity concepts” — for example, providing a presentation “describing the main pillars of energy equity and how they would fit into the transmission planning process, or how to think about that in terms of your existing transmission planning processes.”

In Tier 2, “we’re going to do a deep dive with the applicant into the pool and go into some of [the] details of other transmission planning processes and metrics,” Wetherbee said. Topics “might include developing quantitative energy equity metrics, putting that together with the existing data sets and working with the applicant to go through their current … transmission planning metrics” and cover energy equity measures.

Tier 2 could also look at how to integrate energy equity into cost allocation metrics and transmission economics, he said.

Both tracks will incorporate three components, said Jennifer Yoshimura, the principal investigator for the program at PNNL. A series of listening sessions will begin in October to gather input from a broad range of stakeholders “to understand opportunities for participation as well as barriers,” Yoshimura said. The listening sessions for transmission planners are scheduled for Oct. 1 and Oct. 16.

The ITP will also develop research and resource materials for the general public as well as grid planners “to increase inclusivity as well as equitable outcomes,” she said. The technical assistance component will focus on “capacity building for transmission planners to look at how to incorporate energy equity and justice objectives within their planning processes and paradigms.”

Applications for the program are now open, with a final deadline of Oct. 31, Wetherbee said. Applications will be reviewed in November, and program participants will be announced in December. Both tiers will kick off in January 2025 and run through November.

Eligibility is strictly limited to grid planning organizations, including RTOs, ISOs, utilities and power marketing administrations, such as the Bonneville Power Administration, but DOE and PNNL are looking for diverse participants for each tier, based on geography and equity issues, Wetherbee said.

Tribes often do not have dedicated grid planners, but DOE on Sept. 17 also announced a Tribal Nation Transmission Program, which will provide “educational resources, training and on-call assistance from technical experts and researchers from the National Renewable Energy Laboratory.”

‘We Didn’t Start with Equity’

The historic and ongoing challenges for new approaches to inclusive grid planning are complex, Yoshimura said in her opening remarks at the webinar.

Traditional industry metrics — such as the System Average Interruption Duration Index, or SAIDI — focus on “system averages that can hide vulnerabilities at the household level,” she said. “We see an increase of threats and vulnerabilities involved, whether individuals with ill intentions to harm substations or transmission lines [at risk from] increasing wildfires. …

“Within transmission planning processes, we have seen an emphasis and research focusing on integrated distribution planning, as well as energy transitions on the generation side,” she said. “But there are a lot of opportunities still needed to include equity and equity objectives within transmission planning” in ways that drill down to the granular, household level.

A question-and-answer session following the official presentation reflected some of the challenges ahead.

One participant asked if the ITP program would address ways to improve the National Environmental Policy Act process, the environmental reviews that can slow down and delay the siting and permitting of transmission projects.

Bethel Tarekegne, a PNNL research engineer, said whether the program would cover NEPA was still being discussed, while Yoshimura stressed that NEPA reviews are primarily part of siting and permitting processes, not planning. The Grid Deployment Office has other programs focused on siting and permitting, she said.

DOE and PNNL staff also were asked if they could provide any examples of transmission planning that resulted in equitable participation or outcomes, but none of them could.

“A lot of transmission today is really built around reliability, economics and public policy,” said Patrick Maloney, a power system engineer at PNNL. Lacking examples, he suggested that “allocation of costs might be thought of as a way to bring some equity into the transmission planning process.”

Yoshimura also came up empty on examples. “Our systems and institutions and policies, we didn’t start with equity, yet we’re trying to get to equitable outcomes,” she said. “And so, I think projects like this, listening sessions, case studies and how we learn from each other will help us move in the direction that we need.”

NYISO Offers Final Staff Recommendations for Demand Curve Reset

NYISO presented its final interim staff recommendations for the demand curve reset for 2025-2029 at the Installed Capacity Working Group’s meeting Sept. 10, with minor updates to some metrics.  

The recommendations remain largely the same as the draft presented in August, with the two-hour battery energy storage system (BESS) as the representative lowest-cost peaker plant technology. (See NYISO Presents Draft Recommendations for Demand Curve Reset.) 

As part of calculating the cost of new entry for a hypothetical peaker plant, Zach Smith, senior manager of capacity and new resource integration for NYISO, said the ISO opted to factor in land lease payments for the construction period for the hypothetical peaker. Interconnection costs were modified downward across all zones outside of Long Island. The new derating factor for the BESS also was discussed. 

Smith said the interconnection costs were estimated to be higher because it was assumed peakers would require 345 kV, but 200-MW battery storage systems can connect to lower-voltage lines, which cost less. “And it appears to be better aligned with the actual interconnection requests that we are seeing,” Smith added.  

The Analysis Group, NYISO’s consultant on the reset, also updated net energy and ancillary services (EAS) revenues to account for an operator of a BESS plant maintaining their state of charge to meet day-ahead schedules. 

“The change here is that we force the battery to charge more before the peak load window,” said Paul Hibbard, principal of Analysis Group. 

Hibbard said the change causes negligible differences to net EAS revenue across all zones, aside from Long Island, which saw a 12% drop. 

Derating Factor Headaches

Smith said NYISO was recommending a 2.5% derating factor for BESS peakers. The derating factor was calculated as a weighted average of the derating factors that batteries should expect to receive across their 20-year amortization period. 

NYISO does not yet have a class average for BESS units. “The ICAP Manual (Section 4.5) currently establishes that the initial derating factor a new BESS would receive upon entering the ICAP market is based on the NERC class average equivalent demand forced outage rate (EFORd) of pumped hydro storage until three energy storage resources are participating in the ICAP market and have sufficient historical operating data to establish a ‘NYISO class average’ EFORd for energy storage resources,” the ISO said. 

The 2.5% derating factor is based on the assumption that any new BESS would have an initial 9.19% derating factor — the current class average for pumped hydro — for its first year of operation. The derating factor for the second year would be 5.6%, which is the average of 9.19% and 2%, which is the derating factor estimated by NYISO’s consultants. NYISO then assumes a 2% derating factor for years 3 to 20 of the estimated life of the battery. The average over those 20 years is about 2.5%. 

But this prompted questions from stakeholders. 

“I don’t understand how you can make this change without making companion changes to the manual,” said Doreen Saia, of Greenberg Traurig. “The unit that comes online next year isn’t going to get 2.5%. It’s going to get 9.19% unless and until we make changes to our actual rules.” 

Smith clarified the derating factor would be 9.19% for the first year and the average of the 9.19% and the actual availability of the BESS for the rest of its operating life. 

“A unit’s derating factor, once it has sufficient operating experience, is always based on its actual production,” Smith said. 

Open Questions, Open Frustrations

Smith went over several questions NYISO still was reviewing, such as how to take into account sales tax for BESS labor, operations and maintenance costs; investment tax credits for the transmission lines to the plants; and costs of debt and equity. 

Some stakeholders were unhappy that several longstanding questions were not answered and not addressed in the open questions. They said they wanted to see cost declines for battery units included in the analysis. 

“The ISO has recently shown the assumptions that it’s doing in the study with the Department of Public Service and the transmission owners, and it shows an expectation of more than a 50% decline in battery storage costs over the next 10 years,” said Mark Younger of Hudson Energy Economics. This meant a decline in revenues for the battery units; thus, NYISO’s net cost of new entry was about 45% too low. 

Another stakeholder was disappointed NYISO was not proposing to include revenues for BESS units that come from outside wholesale markets, which could include incentive programs from the state and utilities.  

“I think it severely overstates the net CONE of these facilities and therefore it will impose very high, unnecessary costs on New York consumers,” they said.

RTOs Seek More Flexible Compliance in Appeal of EPA Power Plant Rule

ERCOT, MISO, PJM and SPP last week filed a joint brief in the appeal of EPA’s power plant rule seeking more flexibility on compliance, arguing it is needed to ensure reliability. (See Republican-led States Sue EPA over Power Plant Emissions Rule.) 

The four grid operators submitted comments similar to those they made while the agency was working on the rule. (See EPA Power Plant Proposal Gets Mixed Reception in Comments.) 

“Without additional modification, the compliance timelines and related provisions of the rule are not workable and are destined to trigger an acceleration in the pace of premature retirements of electric generation units that possess critical reliability attributes at the very time when such generation is needed to support ever-increasing electricity demand because of the growth of the digital economy and the need to ensure adequate backup generation to support an increasing amount of intermittent renewable generation,” they wrote. EPA’s final rule would strain their ability to maintain the reliability of the electric grid, they argued. 

The grid operators had proposed a “reliability safety valve” that would help mitigate their concerns, but EPA did not include that in the final rule, nor did it explain why, they noted. The grid operators had wanted EPA to provide upfront, clear criteria on the “remaining use of life and other factors” and enforcement discretion; the creation of a subcategory of generators needed for reliability; offering states guidance on how to use a reliability valve; and the creation of “regional reliability allowances” that generators could use in emergencies to avoid penalties under the rule. 

Instead, they argued, the final rule unreasonably discounts that existing fossil generators will need to decide whether to commit to installing untested technology or retire their units years before the compliance deadline with state compliance proposals due in 2026. That could accelerate earlier retirements of generators, the grid operators said. 

The rule requires 90% carbon capture and storage for coal plants that want to run after Jan. 1, 2039, as well as for new and modified natural gas units with capacity factors of 40% and above. Both categories of plants would need to install CCS systems by Jan. 1, 2032. 

“None of EPA’s projected time frames reflect historical rates of adoption of CCS technology for electrical generation purposes, nor does EPA adequately consider the risks that the technologies will not mature in time for [electric generating unit] owners to deploy them,” the grid operators said. 

EPA’s rule did include a short-term reliability mechanism, which requires the declaration of an energy emergency alert 2 before any compliance mitigation can take place. 

“This short-term reliability mechanism that EPA did adopt in the rule thus unduly places the grid — and customers — at greater risk before any short-term relief would be available,” the grid operators said. They “should not have to wait until the heightened level of emergency that an EEA2 declaration represents; they should be able to take proactive measures to address reliability issues upon earlier evidence of deteriorating grid conditions as evidenced by declaration of an energy emergency alert 1.” 

Compliance flexibility should kick in at EEA 1 because at that point, grid operators can still call on emergency generation. By waiting until an EEA 2, grid operators cannot act until they are in a real-time emergency. 

For longer-term issues, states can ask for extended deadlines or lower technology standards, but the grid operators would like to see EPA offer more guidance on that process. 

EPA is not responding to the initial briefs until next month, but the RTOs’ comments did generate some response from others. The Clean Air Task Force and Natural Resources Defense Council filed lengthy comments on grid reliability, arguing the rule was designed to give utilities and system operators the flexibility they need to maintain grid reliability. 

“While EPA has considered reliability issues in its proposal, FERC is the agency with direct jurisdiction over electric reliability,” the organizations said. “As discussed above and as recognized by FERC, the electric grid is undergoing changes unrelated to the EPA proposal, and the proposed regulations are only incremental to these existing forces. FERC and the electric utilities have the responsibility and many tools available to them to ensure reliability as these grid changes occur.”
