PJM PC/TEAC Briefs: July 7, 2020

Load Model Selection

PJM is recommending a 13-year load model using data from 2002 to 2014 for the 2020 reserve requirement study (RRS), a change from the 10-year model (2003-2012) that has been used for the last several years.

Patricio Rocha Garrido of PJM’s resource adequacy department presented the Planning Committee the results of the RTO’s load model selection process, which analyzed 105 different load model candidates for the 2020 RRS for the 2024/25 delivery year. Rocha Garrido said the analysis is based on the 2020 PJM Load Forecast Report released in January.

Stakeholders will vote on endorsing the load model at the August PC meeting.

The load model candidates were compared to PJM’s “coincident peak 1” (CP1) distribution analysis, Rocha Garrido said, which represents the highest load expected for the forecast year, using two separate approaches. The previously selected load model was not one of the top candidates this year, Rocha Garrido said, because of a new CP1 distribution analysis.

PJM is also again making the recommendation to switch the peak week for the MISO, NYISO, TVA and VACAR regions, known as the “world” in the analysis, to a different week in July that doesn’t coincide with its own peak. Rocha Garrido said the switch in world peak week is performed to match historical diversity observed between PJM and nearby regions.

Consultant James Wilson said he agrees with PJM’s methodology and that there is little relevance to whether the world and PJM happen to peak in the same week. Wilson said that what matters is whether the world peak happens in the same hour or a short period of hours as PJM’s peak.

American Electric Power’s David Canter said stakeholders are trying to figure out the impacts of the COVID-19 pandemic on the load forecast. Canter asked if PJM plans to use the latest approved load forecast as a starting point for future load analysis or if alternative updated load forecasts could be used in cases where a major unforeseen circumstance like the current pandemic has happened.

Rocha Garrido said he would talk to fellow PJM colleagues to get their opinion on Canter’s question and provide an answer at the next PC meeting on Aug. 4. He said analysts have seen no major impacts in the load model released in January compared to current data changes from the pandemic.

Manual 14 Changes

Onyinye Caven of PJM presented a first read of changes to Manuals 14A, 14B and 14G, which incorporate Tariff changes from the RTO’s second Order 845 compliance filing.

FERC required PJM to add language on how the RTO handles surplus interconnection service and incorporation of technological advancements in its interconnection process. (See FERC OKs Most of PJM Order 845 Compliance Filing.)

The changes include new sections detailing the requirements for surplus interconnection requests and related definitions. They also include a new definition of permissible technological advancements and a section outlining the evaluation procedure.

PJM is seeking endorsement of the manual changes at the August PC meeting and a final endorsement at the Aug. 20 Markets and Reliability Committee meeting.

Attachment M-3 Update

PJM
AEP Transmission Zone M-3 Process, Athens, Ohio | PJM

Aaron Berner of PJM provided an update on changes since October 2019 to the information exchange process used by transmission owners planning supplemental projects under Tariff Attachment M-3.

Berner said PJM has changed its slide revision process for presentations at committee meetings based on stakeholder requests. Slides, including those of proposed supplemental transmission projects presented at the Transmission Expansion Advisory Committee, now have red lines to show what was changed, Berner said. Projects with larger changes will have both the original and new slide posted.

Efforts are also underway to create an interactive map of proposed projects that is automated and updated in real time to give better insight into what is being proposed in an area of the system. Berner said the current presentation of maps involves manual insertion of objects in a database that results in a “static map.”

PJM is expanding its documentation to help its engineers in managing the M-3 process, including tracking the age of M-3 needs.

Multiple action items previously identified as issues are still being looked at, Berner said, including requests to improve outage tracking on slides, posting TO contact information.

COVID-19 Load Impacts

Weekday load peaks have dropped 8.2% (about 7,700 MW) since the COVID-19 pandemic lockdowns began March 23, PJM’s Andrew Gledhill told the PC in a presentation.

PJM
Estimated impact of COVID-19 on daily peak and energy | PJM

Recent peak impacts have “noticeably eased” because of the relaxation of stay-at-home restrictions and increased air conditioning loads from hotter summer temperatures, Gledhill said.

The average energy reduction has been 8% since March 23. The “drag” on energy use — down 8% since March 23 — has also lessened but not as much as the impact on peak use, Gledhill said. The energy impact now exceeds the impact on the peak.

Transmission Expansion Advisory Committee

Reliability Analysis Update

Berner provided the TEAC with an update on the 2020 Regional Transmission Expansion Plan (RTEP) reliability analysis, highlighting a cost and scope change for the Windsor switching station in the Dominion Energy transmission zone in Virginia. Berner said the project, which was last presented to PJM in August of 2017, includes building a new 230/115-kV switching station connecting to a 230-kV network line.

Dominion transmission zone: Baseline Windsor Switching Station | PJM

As Dominion started examining the project, Berner said, issues were found in relation to maintenance outages with the proposed design and an end-of-life criteria issue. Berner said the station wouldn’t be able to back feed to deliver energy to customers in the area because of the design.

The project change includes moving from three single-phase 30 MVA, 230/115-kV transformers and a spare to two three-phase 84-MVA, 230/115-kV transformers. Berner said the change increases the scope cost from $11.5 million to $17.4 million with an in-service date by December of 2022.

Ed Tatum of American Municipal Power asked Berner for the reason for the move from 90 MVA to 84 MVA in the transformers to serve load. Tatum said it seemed like a “major change in philosophy” by Dominion to move from four single-phase to two three-phase transformers.

Kyle Hannah of Dominion said the change had nothing to do with the amount of load to be served to the customers and more with how to maintain service to the customers when maintenance switching is being done and from feedback from field operations workers to install a more efficient design.

Berner also highlighted a scope change on the 345/230-kV Homer City transformer project in the Penelec transmission zone in Pennsylvania. The project called for a new 345-kV breaker string with three 345-kV breakers at Homer City and moving the north autotransformer connection to the new breaker string.

Concerns arose as a result of the review of the substation, Berner said, resulting in the installation of one new 345-kV breaker and to relocate the 345-kV Homer City-Mainesburg line terminal and 345/230-kV Homer City north transformer terminal. Berner said there is no cost increase for the change in the $7 million project, and the required in-service date remains June 2021.

RTEP Windows Open

The 2020 RTEP window for solutions to reliability violations under PJM, NERC, SERC Reliability, ReliabilityFirst and local TO criteria opened July 1, Berner said, and will remain open for 60 days until Aug. 31. Berner said as of the day of the meeting, about 290 eligible flowgates had been posted in the window with some possible additions to be made within the week.

PJM also opened a second RTEP window for an end-of-life issue on the 500-kV Doubs-Goose Creek transmission line in the Dominion transmission zone. The 30-day RTEP window was also opened on July 1.

The project, which was presented at last month’s TEAC meeting, involves replacing steel lattice structures along the approximately 18-mile-long line. A third-party assessment determined that the towers have corroded to a point of instability and could result in failure and a collapse of the line if left unaddressed.

Tatum asked why two RTEP windows are being opened at the same time.

Berner said the 30-day window is an immediate-need issue and that PJM has leeway in the timing of immediate-need projects through the Operating Agreement.

“Because of the state of the line, we have to move forward as quickly as possible,” Berner said.

PJM MIC Briefs: July 8, 2020

PJM stakeholders unanimously endorsed the sunsetting of a longstanding subcommittee on intermittent resources and accepted the charter of a new committee with a broader mandate at Wednesday’s Market Implementation Committee meeting.

Scott Baker, PJM business solutions engineer, presented the sunset of the Intermittent Resources Subcommittee (IRS) and the charter for the Distributed Energy Resources and Inverter-based Resources Subcommittee (DIRS). The issue was presented for a first read at last month’s MIC meeting. (See “Solar-Battery Hybrids,” PJM MIC Briefs: June 3, 2020.)

The IRS originated as the Intermittent Resources Working Group (IRWG) in 2008 to address issues regarding operations and reliability, energy markets, capacity markets and interconnections, Baker said, and proved to be an “invaluable forum” for discussing issues related to renewable energy, especially as such resources were starting to multiply within PJM.

The new DIRS will be a stakeholder forum on distributed energy resources — defined as energy storage and generation connected to the distribution system and inverter-based wind, solar and storage. With the MIC’s approval, it may also investigate issues related to other resources that are not conventional thermal units, such as run-of-river hydro, pumped storage hydro and fuel cells.

Baker said any solution coming through the new subcommittee will be shaped by the Planning and Operating committees when the solution impacts planning and operations.

One stakeholder said he remembers problems with PJM’s Demand Response Working Group in the early 2000s that “took on a life of its own,” coming up with rule changes that were brought to the higher-level committees and were ultimately voted down. He said he wanted to make sure the same issue wouldn’t happen with the DIRS.

PJM’s Dave Anders said the DR group existed before problem statements and issue charges were a concept, leading to the problems the stakeholder brought up. Anders said that subcommittees can now approve their own issue charges as long as they’re within the scope of their charter, and the DIRS wouldn’t have to come to the MIC for approval of an issue charge.

The first meeting for the DIRS is scheduled for Aug. 3.

PRD Credits Disposition

Members unanimously approved an issue charge to address a disconnect in PJM’s settlement rules regarding payment for price-responsive demand (PRD).

PJM’s settlement rules call for revenues associated with PRD to be credited to the load-serving entity for an area and do not address the roles of electric distribution companies (EDCs) or curtailment service provider (CSPs), meaning some LSEs are paid for PRD service supplied by EDCs and CSPs.

Sharon Midgley of Exelon provided a second read of the problem statement and issue charge calling for the MIC to consider changes to the payment mechanism. PRD providers represent retail customers that have the capability to reduce load in response to prices.

PJM has an increasing share of load responsive to changing wholesale prices as a result of the implementation of dynamic and time-differentiated retail rates and utility investment in advanced metering infrastructure. Several EDCs cleared PRD as a capacity resource for the first time for the 2020/21 delivery year.

The work effort is expected to take six to nine months, Midgley said, with changes implemented in advance of the 2021/22 delivery year.

Performance Assessment Interval Settlement Endorsed

Stakeholders endorsed an issue charge to increase the transparency of settlement calculations for capacity nonperformance charges, with one member voting against the measure in an acclamation vote.

Governing language on the measurement and settlement of performance assessment intervals (PAIs) were drafted as part of the Capacity Performance initiative in 2014, but the first PAI that resulted in settlement did not occur until Oct. 2, 2019. PJM staff said the first settlement indicated the governing documents weren’t clear or detailed enough to provide sufficient transparency into the process.

Susan Kenney of PJM reviewed the problem statement and issue charge for the initiative, which is expected to last six months.

In March, PJM released a report on the PAI settlements as an addendum to its review of the October event, when an abnormal heat wave led to emergency procedures and the first call on demand response resources in more than five years. (See PJM, Stakeholders Baffled by DR event.)

PJM MIC

The incident resulted in $8.2 million in nonperformance charges.

Kenney said special sessions of the MIC will start in September. PJM says there is a lack of clarity on the identification of assessed resources; the calculation of real-time reserve and regulation assignments; calculations for scheduled megawatts; and accounting for resources with both Reliability Pricing Model and fixed resource requirement commitments.

Members balked at a change PJM agreed to make to the issue charge as a result of discussions with the Independent Market Monitor after the first reading at the June MIC meeting.

The inserted issue charge language states, “Rule clarifications developed through this problem statement/issue charge will be documented in the appropriate agreement or PJM manual and, if necessary, used to recalculate prior PAI settlements as applicable.”

Kenney said PJM doesn’t anticipate the need to resettle any prior PAI settlements after work on the issue charge is completed but acknowledged it could occur.

Gary Greiner, director of market policy for Public Service Enterprise Group, said the additional language didn’t seem like something that needed to be included in an issue charge. Greiner said PAI resettlements can always happen if discrepancies are uncovered.

“It seems out of place here, and I would prefer to strike the language,” Greiner said.

Midgley supported Greiner’s comments and said the stakeholder process should be focused on prospective changes. Midgley said the inserted language seemed “inappropriate.”

Monitor Joe Bowring said he disagreed with the removal of the language from the issue charge. He said the language was meant as a clarification and to put stakeholders “on notice” that resettlements could happen after work is completed.

PJM decided to remove the language before the issue charge was brought to a vote.

MOPR Subsidy Guidance

Paul Scheidecker, PJM senior lead engineer, teamed up with Alexandra Salaneck of Monitoring Analytics to provide an overview of the “guidance document” the RTO and the Monitor will provide capacity providers to identify which programs they consider state subsidies under the expanded minimum offer price rule (MOPR).

Scheidecker said PJM and the Monitor will create and update the list of subsidy programs based on information provided by capacity market sellers. She said the guidance document is not intended to be legal advice; capacity market sellers will be responsible for certifying whether a capacity resource is subject to a state subsidy.

Requests for program reviews will be submitted through the Monitor’s Member Information Reporting Application (MIRA) system, Scheidecker said, with PJM and the Monitor reviewing all requests collaboratively. A public notice of all MOPR determinations will be posted on PJM’s website, Scheidecker said.

Where PJM and the Monitor come to different conclusions, both determinations will be noted.

ARR/FTR Market Task Force Update

Dave Anders, PJM | © RTO Insider

PJM’s Anders provided an update on the ARR/FTR Market Task Force, telling stakeholders that the RTO has issued a request for an independent consultant to do a review of the auction revenue rights and financial transmission rights market constructs.

The hiring of a consultant was one of the recommendations in last year’s independent consultant report on the GreenHat Energy default. The review is anticipated to take 12 weeks. (See PJM Revises Consultant Scope for ARR/FTR Review.)

Anders said PJM is now looking for feedback from stakeholders to decide if the ARR/FTR Market Task Force should go on hiatus as the consultant review is conducted or to continue work. Anders said a nonbinding poll is now open on PJM’s website, and the responses will be used to form the task force’s recommendation to the MIC regarding the next steps for the group.

Poll responses are due by 5 p.m. ET this Thursday. Both voting and affiliate members are allowed to respond once each to the poll.

PJM Stakeholders OK PMU Requirement

PJM stakeholders endorsed “quick-fix” manual revisions to expand the use of synchrophasors and make them a requirement for certain projects under the Regional Transmission Expansion Plan (RTEP).

The revisions, which have been debated for several months at the Planning Committee, passed with 89% support and 136 “yes” votes at the committee’s meeting July 7. Members were originally scheduled to vote at last month’s PC meeting, but several stakeholders raised objections over PJM’s proposals. (See PMU Vote Delayed by PJM.)

PJM PMU Requirement
Dave Souder, PJM | © RTO Insider

Dave Souder, PJM’s senior director of system planning, said the proposed solution was modified based on stakeholder feedback over the last month. Souder said language was changed to indicate the synchrophasor requirements will only apply to new baseline and supplemental projects presented to the Transmission Expansion Advisory Committee or the subregional RTEP committees for inclusion in the RTEP after June 1, 2021.

Shaun Murphy of PJM reviewed the problem statement, issue charge and proposed solution of language in Manual 1 and Manual 14B requiring synchrophasors — also known as phasor measurement units (PMUs).

For new substations with three or more non-radial transmission lines at 100 kV or above, synchrophasor measurement signals will be required for:

  • bus voltages at 100 kV and above;
  • line-terminal voltage and current values for transmission lines at 100 kV and above;
  • high-side/low-side voltage and current values for transformers at 100 kV and above; and
  • dynamic reactive device power output (SVC, STATCOM and synchronous condensers).

The manual language adds a PMU Placement Strategy (PPS) including placement targets and required operational dates for the devices needed to support PJM’s real-time synchrophasor applications.

| PJM

Murphy said PJM’s vision for the “grid of the future” includes a system with full observability of all equipment of 100 kV and above and that synchrophasors are a key part of that. He pointed out the benefits of PMUs, including the ability to detect grid disturbances from oscillation events and equipment failures in real time and the ability for detailed analysis after a major outage.

The installation of PMUs was a recommendation following the Northeast blackout of 2003, Murphy said, an event that lasted for four days, impacted 50 million people and carried an estimated cost of $6 billion.

Costs Questioned

PJM estimates costs of about $8 million for as many as 80 PMU installation projects annually based on historical numbers of substation projects proposed in the RTEP process. The RTO said it costs about $120,000 to make a substation “PMU ready” in addition to the $10,000 cost for a single PMU.

PJM PMU Requirement
Ruth Ann Price, Delaware | © RTO Insider

Delaware Deputy Public Advocate Ruth Ann Price said she was still not clear as to how many PMUs the RTO is looking to install.

Souder said the most recent query of the PJM energy management system found 4,100 substations at 100 kV and above. PJM currently has about 400 PMUs in place, he said, most of them installed between 2009 and 2013 with funding from the U.S. Department of Energy’s Smart Grid Investment Grant.

PJM’s approach is to do PMU installation in a “cost-effective manner,” Souder said, focusing on substation projects where PMUs can be built into the engineering and design stage rather than having to go back to retrofit a substation.

Souder said PJM has also committed to re-evaluating its PMU strategy every five years to move forward selectively when enough synchrophasors are in place to provide accurate, real-time information. Souder said the installation process will take at least 10 years to get to a point of system effectiveness, but not all of the 4,100 substations that fit the installation criteria will need to have PMUs for the monitoring system to work.

Stakeholder Opinions

Dave Mabry of the PJM Industrial Customer Coalition said he still had concerns that the proposed manual language will increase the justification of supplemental projects, which are reserved for incumbent transmission owners and not subject to competitive bidding.

PJM PMU Requirement

Greg Poulos, executive director of the Consumer Advocates of the PJM States, said the advocates are very supportive of innovation but are concerned by the cost-benefit analysis. He said the installation of smart meters over the last decade has been an expensive endeavor whose cost has outweighed the benefits in some cases.

“As those who will be paying for this, the cost-benefit is going to be the number one question I get,” Poulos said.

Adrien Ford of Old Dominion Electric Cooperative said she went into the PC meeting last month expecting to endorse the proposed manual revisions but was glad to take more time after additional questions were raised by stakeholders. Ford said the extra month of discussions with PJM over the manual language led to important changes that made the solution stronger.

“I think this is a good example of collaboration between stakeholders and PJM to get the manuals strengthened with input,” Ford said.

PJM OC Briefs: July 9, 2020

The PJM Operating Committee on Thursday unanimously endorsed a “quick fix” solution to give transmission owners access to the Dispatch Interactive Map Application (DIMA), a geospatial situational awareness program that RTO dispatchers have used since 2014.

Ed Kovler, PJM’s senior lead business solutions architect, presented and reviewed the problem statement and issue charge on expanding access to DIMA, which allows operators to see the location of problems on the grid in real time. The quick fix was first presented at the June 4 OC meeting. (See “Dispatch Interactive Map Application,” PJM Operating Committee Briefs: June 4, 2020.)

John Sturgeon of Duke Energy said his company is supportive of TOs having access to DIMA. He asked if there has been any discussion by PJM on the cost of the program and if costs will be passed off to all TOs.

Kovler said PJM had initially considered charging for access to the application, but a decision was made to open it to all TOs at no additional cost. He said costs will be integrated into PJM’s budget.

PJM Operating Committee
DIMA geospatial overview | PJM

Tonja Wicks of Duquesne Light Co. asked if confidential information could be added to DIMA and if TOs will be informed by PJM before any changes in information access are made.

Kovler said there are no plans to add any information beyond what has already been demonstrated. The RTO would have to develop a governance process if additional data is added in the future, he added.

PJM plans to present the DIMA issue charge at the July and August Markets and Reliability Committee meetings and the September Members Committee meeting. If endorsed, the Operating Agreement changes will be sent to FERC in September for approval.

COVID-19 Operations Update

Pennsylvania’s move to the “green phase” for reopening from the COVID-19 shutdown has not had a major impact on PJM’s operations, Paul McGlynn told the committee in an update on the RTO’s pandemic operations plan.

McGlynn said most staff continue to telecommute, while control room workers have gone back to a “normal configuration” of two control rooms. He said procedures augmenting operations support staff during critical operating periods have been established.

The current procedures will be in place through at least Labor Day, McGlynn said, and PJM staff will continue to monitor infections in the area and adjust operating plans as needed.

“The PJM plan is flexible and cautious,” McGlynn said.

Stakeholders asked about the year-end deadline PJM instituted for market operations centers that interact with the RTO to operate remotely from their main offices and whether any consideration is being given by the RTO to extending the deadline, as many businesses will continue to operate remotely into 2021.

Mike Bryson of PJM said there were certain compliance concerns regarding keeping the deadline open-ended, but he said extending the deadline should not be an issue if it’s needed.

Synchronous Reserve Review

Rebecca Carroll, PJM’s dispatch director, reviewed the findings from the RTO’s inquiry into why shortage pricing was not triggered during a June 3 incident when synchronized reserves fell short in real time. The report was requested by several stakeholders at the June OC meeting.

Carroll said PJM’s synchronous reserves dipped below the requirement by about 50 MW for about four minutes, from 4:02 to 4:05 p.m. ET.

Real-time security-constrained economic dispatch (RT SCED) case approvals can commit additional reserves to meet the requirement based on the available resources in a 10-minute look-ahead, she said. Real-time synchronized reserves involve an instantaneous calculation of available reserves.

PJM Operating Committee
PJM’s synchronous reserves dipped below the requirement by about 50 MW for about four minutes, from 4:02 to 4:05 p.m. ET. | PJM

The phenomenon seen on June 3 happens “occasionally,” Carroll said, where generation is either not following the base points sent by PJM or load comes in higher than the forecast. Carroll said the reserves were being fully met by Tier 1 resources at the time and that PJM saw a “significant amount” of Tier 1 generators that were over-generating.

Carroll said generation dispatchers received an alarm the second reserves dipped below the reserve requirement and were able to commit additional condensers to restore the reserves to the requirement.

Gary Greiner, director of market policy for Public Service Enterprise Group, suggested PJM should use both Tier 1 and 2 resources to avoid what happened June 3. “When you have diversity in supply, you can better address situations like this where you’re over-generating,” he said.

Carroll replied that the decision to go with Tier 1 resources is solely based on economics. If there’s enough Tier 1 reserves, she said, the RT SCED engine will use that to solve any problems because it’s the cheapest.

The issue will not exist when Tier 1 is eliminated because of FERC’s ruling in May approving PJM’s proposed energy price formation revisions that consolidate Tier 1 and 2 reserve products, she said. (See FERC Approves PJM Reserve Market Overhaul.)

Black Start Fuel Requirements Update

David Schweizer, PJM’s manager of generation, provided an update on the work plan for the fuel requirements for black start resources. The work was put on hiatus in March pending refining of proposals and costs with stakeholders. (See PJM Backs off Black Start Fuel Rule.)

Schweizer said the intent of additional analysis was to provide further supporting information and to better inform stakeholders regarding the impact of any of the packages proposed.

Technical analysis being done by PJM is focusing on enhancing the previous restoration impact analysis, Schweizer said, which looked at the incremental increase in restoration time analysis if non-fuel-assured black start resources are unavailable during a restoration event.

PJM is also investigating potential gas pipeline and supply issues impacting restoration, Schweizer said, including studying the impacts of the loss of power to gas compressor stations.

Schweizer said work was delayed in the spring because of the COVID-19 pandemic, but PJM hopes to have its analysis done and to restart the stakeholder process by the end of 2020.

Colo. ALJ Proposes $235M Exit Fee for United Power

A Colorado administrative law judge on Friday recommended to the state’s Public Utilities Commission that it accept United Power’s exit-fee methodology in its long-running dispute with Tri-State Generation and Transmission Association, saying United and fellow complainant La Plata Electric Association (LPEA) were treated in a “discriminatory manner” (19F-0620E, 19F-0621E.)

Under the recommended methodology, United would pay Tri-State $234.8 million, a figure United said was “comparable” to payments made by other members leaving the cooperative. Tri-State had proposed a charge of $1.25 billion, an amount that would have resulted in an “unfair windfall” to the association’s remaining members, United said.

LPEA would pay almost $97 million to leave Tri-State under the ALJ’s recommendation. The cooperative has not been offered an exit fee by Tri-State.

FERC in June accepted Tri-State’s proposed contract-termination payment (CTP) methodology for filing but also set hearing and settlement judge procedures. The commission said it could not resolve issues of material fact based on the existing record and that the CTP methodology had not been shown to be just and reasonable (ER20-1559). (See FERC Sets Tri-State’s Exit-fee Rules for Hearing.)

United in May filed a lawsuit in a Colorado county district court against what it called a “civil conspiracy” to deprive state regulators of jurisdiction over Tri-State’s exit fees. That proceeding is pending, but a Colorado ALJ in the meantime rejected Tri-State’s defense that the PUC lacks jurisdiction.

The parties have 20 days to file exceptions to last week’s decision, after which the PUC will then consider the complaint.

United has been trying for more than two years to arrange an exit from Tri-State before its wholesale service contract expires in 2050.

“We recognize this is just the next step in a long process,” said Bryant Robbins, acting United CEO, in a statement. “It’s our goal to provide reliable power to every family and business we serve, and to provide that power at a cost that makes sense. We carefully considered our obligations to Tri-State and developed what we believed was a fair exit cost.”

In a competing statement, Tri-State CEO Duane Highley said efforts “to protect the interests of all our cooperative members and their electricity consumers” will continue before the PUC and FERC, and he issued a warning to the cooperative’s members.

United Power exit fee

“If this decision is allowed to stand, more than $1 billion in costs will be unjustly added to our members’ electricity bills in Colorado, Nebraska, New Mexico and Wyoming,” Highley said. “In an effort to save money for themselves, United Power and LPEA are a step closer to forcing costs they agreed to pay onto smaller, less wealthy utilities and their rural consumers.”

Tri-State said the recommendation would result in a contract termination figure “that is far below any fair value” of the two utilities’ contracts and “well below” their share of the association’s debts and other obligations. It said United’s share of its outstanding debt and other obligations is approximately $762 million.

The association also noted that United and La Plata both “freely signed” long-term power contracts with it in 2007 and agreed to share the supply costs with other utility members. It also said the CTP methodology was developed by its utility members and that they all can participate in the FERC settlement and hearing process.

The two utilities are among Tri-State’s three largest members. United is the largest, with about 15% of electric demand thanks to its 93,000 members in Denver’s northern suburbs. La Plata is the third largest among Tri-State’s 42 distribution utility members, with more than 34,000 members in southern Colorado.

Calif. Rushing Microgrids for Fire Season Shutoffs

California is moving quickly to adopt microgrids to store wind and solar energy and to provide electricity during public safety power shutoffs (PSPS) in wildfire season, but long-term energy storage and resilience remain problems, panelists said last week at a California Energy Commission workshop on “Assessing the Future Role for Microgrids.”

Leaders of the CEC, the California Public Utilities Commission and CAISO met in three sessions over two days during the workshop, hearing from panelists and presenters on the challenges and promise of microgrids: small-scale generation and distribution systems that can power a single building or a whole community.

Over a total of six hours, participants discussed using microgrids to offset fire-prevention blackouts starting this fall and, in the longer term, to store renewable power and make up for possible capacity shortfalls during the switch from natural gas plants to renewable resources in the next three years.

Senate Bill 100, passed in 2018, requires load-serving entities to provide only zero-carbon electricity to retail customers by 2045.

“Microgrids are one of the tools that will help the state get to our 100% clean energy standard in the most efficient and equitable way possible,” said CEC Vice Chair Janea Scott, who led the sessions.

CPUC President Marybel Batjer said she’s worried about Pacific Gas and Electric’s plan to use diesel generators to supply electricity during PSPS events this summer and fall. PG&E intends to connect hundreds of diesel generators at substations to supply customers during the shutoffs.

“I am concerned that this wildfire season, we will see a lot of diesel generation used to ensure resiliency, and we have to get to a cleaner and quieter form of resiliency backup power,” Batjer said.

Neil Millar, CAISO’s vice president for transmission planning and infrastructure development, said it was important for the ISO to learn about the “different flavors of microgrids that are evolving” and to ensure “our existing processes are adequate for accommodating them.”

CAISO and the CPUC are working to manage the connection of microgrids to the statewide grid and to include microgrids in the state’s resource planning process, he noted.

Fast-tracked Measures

Senate Bill 1339, passed in 2018, directed the CPUC to “facilitate the commercialization of microgrids for distribution customers of large electrical corporations” by Dec. 1.

In response, the CPUC established a new section in its Energy Division focused on microgrids and fast-tracked rulemaking to speed the connection of microgrids in anticipation of this year’s fire season, which typically lasts from late summer through November.

In June, it adopted a proposed decision ordering investor-owned utilities to streamline and expedite interconnection processes for microgrid resilience projects and to work with local and tribal governments to bring the projects online by late summer, in time for the anticipated power shutoffs. (See California PUC Approves Microgrids, Fire Plans.)

The CPUC directed energy storage facilities to import power from the grid prior to PSPS events. It permitted PG&E to upgrade substations and install diesel generators, but only for the 2020 fire season. And it ordered IOUs to increase staffing to hasten microgrid interconnections.

“We’re really focused on … fast-tracking near-term strategies and actions we can put in place in time for this year’s wildfire season,” PUC Senior Analyst Jessica Tse said during the first microgrid workshop session on July 7.

Beyond the next few months, the CPUC and CEC are seeking ways to build microgrids that use wind and solar with battery storage to ride out power outages. (See CPUC Proposal Would Promote Microgrids.)

The CEC is funding millions of dollars in pilot projects to find microgrid solutions that can be replicated and installed on a larger scale. The projects are on military bases and tribal lands, at ports and airports, in industrial settings and wastewater treatment plants, and in low-income and disadvantaged communities.

Projects recently approved include $6 million to determine if it might be feasible to use banks of batteries that have been removed from electric vehicles, but still have plenty of useful life, for storage in microgrids. With 750,00 EVs sold so far, and millions more expected to hit California roads in the next decade, there will be a lot of used batteries, CEC Chair David Hochschild said. (See Calif. Energy Commission OKs $22M for Storage.)

In another CEC-funded project, the city of Fremont is using solar and battery storage to allow critical facilities such as fire stations to “island” from the grid for up to three hours. But local jurisdictions need the ability to provide power while disconnected from the grid for longer periods, said Rachel DiFranco, the city’s sustainability manager.

PG&E’s fire-safety blackouts in the fall of 2019, affecting hundreds of thousands of customers, lasted for days at a time. (See CPUC Orders Changes to PG&E Shutoff Rules.)

Earthquakes and wildfires could sever ties to the grid for even longer periods, said Rosa Vivian Fernández, CEO of the San Benito Health Foundation, a small clinic that serves thousands of farmworkers in the city of Hollister. In August 2019, San Benito became the first health care facility in California to run entirely on its own zero-carbon microgrid using a rooftop solar array and lithium-ion battery storage.

Fernandez said she learned from visiting Puerto Rico after Hurricane Maria in 2017 that health care facilities could be disconnected from power for weeks, unable to serve patients.

“When disaster strikes … [you] may have severe damage to infrastructure,” she said during the first of Thursday’s two workshop sessions.

Seth Baruch, director of energy and utilities for health care giant Kaiser Permanente, explained why Kaiser had decided to install microgrids at a growing number of its facilities.

In 2018, the Kaiser Permanente Richmond Medical Center was the first hospital in California to install a renewable-energy microgrid for backup power during outages. Hospitals generally use diesel generators for emergency power, but Kaiser is pursuing microgrids as it seeks to become carbon neutral and because diesel fuel can run short in emergencies, Baruch said.

“When you need diesel, everyone needs diesel,” he said. With power shutoffs and potential surges in COVID-19 cases, Kaiser wants to ensure its facilities have power “24/7” for days at a time, he said.

Hydrogen Fuel Cells

The need for microgrids that can supply long-term backup power prompted a discussion Thursday, during the workshop’s final session, on deploying microgrids that use hydrogen fuel cells, which produce electricity through an electrochemical reaction of hydrogen and oxygen.

Lithium-ion batteries can only provide power for short-duration outages. Fuel cells can provide power indefinitely given a supply of hydrogen and oxygen produced by separating water into its components with a solar-powered electrolyzer, advocates said Thursday.

Stone Edge Farm, a 16-acre Sonoma County winery, has a microgrid with solar panels, batteries, an electrolyzer that produces hydrogen from rainwater and a bank of hydrogen fuel cells, winery owner Mac McQuown told commissioners.

“Our objective in our microgrid is to be independent of the utility grid 24/7, 365,” McQuown said.

Microgrids using fuel cells power a low-income housing community in Brooklyn, a college in Bridgeport, Conn., and a high school and fire stations in Woodbury, Conn., said Jack Brouwer, director of the National Fuel Cell Research Center at the University of California, Irvine.

“Fuel cells have this opportunity to do that because they have very high power capabilities to power a whole community,” Brouwer said.

The big problem is cost. In applications such as microgrids, fuel cells produce electricity at $4,000 or more per kilowatt, the NFCRC says on its website. Fuel cells would be competitive in providing power for stationary loads if they reach an installed cost of $1,500 or less per kilowatt, it says.

Current research is seeking to reduce costs by using less expensive materials and producing fuel cells on a larger scale, the NFCRC says.

Brouwer said using hydrogen technology in conjunction with wind, solar and battery storage is another way to make fuel cells more practical. Existing natural gas pipelines might also be able to carry hydrogen, but that idea has proven controversial among clean-energy advocates who want to do away with natural gas entirely, he said.

Still, he said, California may ultimately need hydrogen fuel cells to provide electricity during long outages and to meet its ambitious decarbonization goals.

Hydrogen can “deliver resilience for weeks on end,” Brouwer said, and “the solution to get all the way to zero [carbon] needs something like fuel cells and hydrogen.”

Millar, with CAISO, said he agreed. “The solution here isn’t one or the other; it’s all of the above,” he said.

Electricity Industry Asks for Regulatory Certainty

Former FERC Commissioner Philip Moeller told the current commissioners last week that demand destruction is the electricity industry’s primary concern during the COVID-19 crisis.

Moeller, now executive vice president of the Edison Electric Institute’s business operations group and regulatory affairs, said that the longer it takes to flatten the curve of coronavirus cases, decreasing demand becomes a larger problem.

“I don’t know how long [the recovery will take], but if demand stays lower for an extended period of time, that takes on added risk,” he said during a panel on access to capital Thursday, the second day of a commission technical conference on the pandemic’s impact on the energy industry. “The cost of equity is higher, and despite the lower interest rates, that is a risk the market has put into the price of capital.”

In June, EEI asked FERC for expedited action on the Notice of Inquiry the commission opened on return on equity policies last year (PL19-4). (See FERC Opens Inquiries into Tx Incentives, ROE Policies.)

“We hope FERC comes up with policy that helps with stability [and] continues to attract [capital] needed to build [transmission] infrastructure,” Moeller said. “It’s getting more and more difficult to build major energy projects. It’s worth remembering that all transmission projects, regardless of who develops them … [go] through a vigorous process. Whether it’s the engineering contract or the construction contract, those are laborious projects in themselves before a project gets the greenlight to go ahead.”

CAISO General Counsel Roger Collanton, speaking for the ISO/RTO Council, said liquidity is the most immediate concern for market participants.

“COVID-19 has caused some disruption in the financial markets, which could affect liquidity sources for market participants to cover their positions,” he said. “In addition, some market participants’ revenue streams may be impacted by declining loads and nonpayment for retail services. This does not mean we can relax our monitoring of credit risk. We must remain even more vigilant during these uncertain times.”

Collanton said the grid operators monitor for credit downgrades and unexpected default rates that could lead to lower amounts of unsecured credit limits. Market participants whose credit ratings fall beneath investment grade would be forced to post only secured forms of collateral for all outstanding liabilities without an allowance for unsecured credit, he said.

“The majority of the market participants qualifying for unsecured credit use only a fraction of their limit to handle the day-to-day variances in their outstanding liabilities,” Collanton said. “However, if a market participant’s declining financial health has led to the elimination of unsecured credit limits in wholesale electricity markets, it has likely led to elimination of unsecured credit in other markets, which could begin to pose a liquidity problem.”

He noted FERC has recently allowed some RTOs to impose higher credit requirements on market participants that may pose a higher credit risk.

“In part, this discretion will allow these ISOs/RTOs to assess the positions of market participants that may not operate physical assets and may create asymmetric risks between themselves and the rest of the market,” Collanton said.

He suggested the commission remind state regulatory commissions to monitor load-serving entities’ financial health and the importance of maintaining credit protections.

FERC regulatory uncertainty

FERC Commissioner Bernard McNamee | FERC

Asked by Commissioner Bernard McNamee whether infrastructure investments will continue given the pandemic, American Electric Power’s Antonio Smyth, senior vice president of transmission ventures, strategy and policy, noted that his company has already shifted $500 million of capital spending from 2020 to 2021.

“This really highlights and underscores the importance of the commission continuing to adopt solid ROE policies and mechanisms that are put in place to allow us to continue to invest,” Smyth said. “If we don’t invest today, we’ll certainly suffer the consequence tomorrow.”

Christine Tezak, managing director of ClearView Energy Partners, noted the energy sector is not immune from movements in the global economy.

“This is not leaving anyone untouched,” she said. “Where the commission is going to need to exercise its discretion is discerning where there are developing problems. These are cyclical markets, and the commission needs to recognize it would be asking itself to accomplish a superhuman feat to predict all cyclicality in cyclical markets. I think there’s good faith on Wall Street that state regulators are going to work with utilities and work on recovery of bad debt over some period of time.”

Kinder Morgan President Kimberly Dang said access to capital has improved since the Federal Reserve’s market interventions in March and April, but it has gotten more expensive.

“That has unleashed uncertainty into the industry,” she said. “Projects are more difficult to get done in this environment, and that’s going to drive up required returns. Needed projects are not getting built. We need as much certainty as possible. We can’t have contractors sitting on the right of way.”

Several other panelists weighed in on the danger of regulatory uncertainty.

“The power industry has done a phenomenal job in maintaining reliability and keeping the lights on. I believe we have the tools to manage through right now,” NRG Energy CEO Mauricio Gutierrez said. “The biggest risk, when I talk to investors, is regulatory risk and regulatory intervention. Changing the rules in middle of the game is the biggest risk to investing in the power grid.”

“Our industry is the most capital-intensive industry in America,” Moeller said. “Because of the long-term nature of these investments, we appreciate the extent to which the commission is working to provide that certainty, so we can provide reliable, safe electricity.”

Smyth reminded the commission of the transmission system’s “vital, reliable service, which goes back to the base ROE.”

“We believe the commission should continue with its work to adopt a sound ROE policy,” he said. “On the incentives front, well-crafted ROE policies will ensure the grid works for customers, both today and in the future.”

Duke Energy CFO Steve Young closed the panel discussion by complimenting FERC on its “very fair and balanced view” of the risk associated with building, owning and operating long-term infrastructure.

“Having a healthy respect for that risk, as they set ROEs and recovery policy, is very valuable,” he said. “That allows us to effectively raise capital and gives the investor confidence. They’ve done a good job of that over the years.”

Gas Sector Finds Some Capital Available

Another panel Thursday explored the COVID-19 pandemic’s effect on natural gas and oil supply, demand, transportation and infrastructure planning.

Anatol Feygin, chief commercial officer for LNG giant Cheniere Energy, told McNamee the natural gas industry finds itself in a “very challenging time.” Some sectors have ready access to the capital markets, but others don’t, he said.

“Parts of the industry fall under the infrastructure umbrella where, in a low-interest-rate environment, it has plenty of capital. Hundreds of billions of dollars have been raised on the infrastructure side of world,” Feygin said. “The upstream space is working to morph its business model and economics … to offer the types of return that are attracting … investment. It’s a difficult transition.”

Several panelists said the rapid growth of COVID-19 cases and the ensuing lockdowns caught them off-guard, in contrast with the 2008-2009 financial crisis.

“In 2008 and 2009, we could kind of see that coming a little bit. There was more time to react to it and more time to recover,” said Gary Gibson, CEO of City Utilities of Springfield (Mo.). With the COVID-19 crisis, “we saw some pretty immediate changes in our industry and what consumers were doing. Going forward, we still have issues of when we could shut down again. If we continue in that direction, we’ll see more demand destruction that will continue for several years.”

“There were some lessons learned previously,” he continued, “but we’re learning new lessons now.”

“In 2008, when the economy recovered and our industry’s access to capital was still there, it transformed our industry to be the world lead for gas production,” said EQT CEO Toby Rice, alluding to the shale drilling revolution. “Now, with a lack of returns, there’s very cautious thinking. A lot of people have concerns whether that access to capital returns for the energy industry. We have to ensure we still have access to capital to keep our economy strong, our energy cheap, improve the environment and enhance the national security of our country. We have to be more efficient, to allow the market to be more efficient.”

Community Shared Solar Grows in NYC

New York continues to be a pioneer in expanding access to community solar for low- and moderate-income people, and the New York City Housing Authority (NYCHA) is a powerful agent in that effort, with more clients than the population of most U.S. cities.

NYCHA has a commercial solar program and a residential one, the ACCESSolar program, which aim to install 25 MW of renewable energy on its properties by 2025, generally at less than 40 kW per building, Chris White, an associate with the housing authority’s capital projects/sustainability program, told more than 100 people Thursday in a virtual meeting hosted by Sustainable CUNY at the City University of New York.

The housing authority completed its first round of solicitations last year, with the pandemic greatly disrupting the progress so far in 2020, he said.

“Right now, we’re trying to work through COVID, wrap up some lease agreements and get our first projects constructed. We’re hoping that our first solar panels will be in construction in the next couple of months … and hopeful that we’re going to have our next round of solar opportunities probably around the end of this year,” White said.

The solar program aims to generate revenue, use underutilized spaces, provide job training and green jobs for residents, and reduce energy costs for those who live in NYCHA housing, Section 8 voucher holders and other low- and moderate-income people across the city, White said.

The housing authority serves about 400,000 people in 176,000 apartments and another 200,000 people through its voucher program, the largest numbers of any city in the country, and gets special reduced electricity rates from the New York Power Authority, he said. (See New York City Ramps Up Community Solar.)

Ron Reisman, NYC solar partnership manager for Sustainable CUNY, said the organization has been supporting NYCHA’s program from the beginning three years ago with technical assistance, assessments, proposal evaluations and other services.

Sustainable CUNY developed the New York solar map and portal, which includes a calculator to help residents find the solar potential of their homes or businesses. It includes links to resources on permitting, interconnections, zoning, financing and other topics related to solar and storage, Reisman said. The organization supports both renewable energy development on the university’s campus properties and for New York’s distributed generation framework, he said.

Sharing Benefits

“Supporting the NYCHA initiative is part of our overall mission to expand the deployment of solar in New York City, and energy storage as well, in a way that all New Yorkers can take advantage of energy, environmental and economic benefits,” Reisman said.

The National Renewable Energy Laboratory’s webpage on low- and moderate-income solar policy basics notes that community solar is attractive to many regardless of income, because shading and inadequate roof conditions make solar unsuitable for nearly three-quarters of the residential rooftops in the U.S.

The lab says several jurisdictions have begun exploring community solar to expand solar access to low- and moderate-income communities, and mentions New York as one of four states — California, Colorado and Oregon are the others — that have enacted low-income carve-outs as part of their community solar policies.

The New York Public Service Commission’s 2015 order establishing net metering gave special consideration to projects that promised 20% participation by low-income people (15-E-0082).

“We’re very excited about the work we’re doing installing solar at the [NYCHA’s] Carver Houses,” said Charles Callaway of WE ACT for Environmental Justice, who also has a seat on the state’s 22-member Climate Action Council. “If we weren’t in this pandemic of COVID-19, we’d probably be in the buildings.”

His organization is looking to recruit a couple buildings in East Harlem into the solar program and working to get residents the cost estimates needed to move forward on installing solar panels.

“Getting people the information they need to sign up for community solar is very important,” Callaway said. “We’ve tried a couple of strategies around just doing street outreach.”

Callaway reported some low-income people being fearful of innovative clean energy programs after having been “scammed” by unethical energy service companies, a practice that the PSC has cracked down on repeatedly in recent years. (See NYPSC Reins in ESCOs, Expands Community DG.)

The mayor’s office works with Sustainable CUNY and the NYC Economic Development Corporation to expand access to the benefits of solar energy and other forms of renewable energy. Programs include Solarize NYC — for community group purchasing — and a related program called Shared Solar NYC.

Juan Parra, community solar program manager with Solar One, an environmental education nonprofit in the city, said his organization is involved in two active projects now: a 685-kW project in Sunset Park, on the roof of the Brooklyn Army Terminal, and NYCHA’s ACCESSolar.

“We’re implementing workforce training opportunities, so we’re not just training folks in solar installation skills, but actually making commitments with the installer to hire them as part of the solar installations for these projects,” Parra said. “We’re excited that training is going to start next week.”

Daphany Sanchez of Kinetic Communities Consulting worked with NYCHA on the solar project and said the housing authority is working in Harlem to learn how to scale community solar for small businesses and local nonprofits.

“Community-based organizations have done outreach in the past, so when we talk about community solar outreach, the concerns are around how do we ensure these are truly low- and moderate-income people, how do we capture that information, when in reality such organizations” have secured the same personal information for housing, health and education, Sanchez said. “It is not new.”

ERCOT Briefs: Week of July 6, 2020

ERCOT said last week that its corporate members have approved the elections of two unaffiliated directors, the re-election of a third unaffiliated director and amendments to the grid operator’s amended and restated bylaws.

Staff conducted a ballot vote “to resolve the items” before a scheduled Friday special meeting of corporate or voting members. They received enough votes to pass each of the four motions on July 2 and canceled the special meeting.

ERCOT plans to file the three director nominations for approval with the Texas Public Utility Commission this week. It expects approval in early November.

The Board of Directors in June approved Michigan Public Service Commission Chair Sally Talberg and retired ERCOT Board of Directors Briefs: June 9, 2020.)

Board Chair Craven Crowell, Vice Chair Judy Walsh and Director Karl Pfirrmann all roll off the board when their terms expire at the end of this year.

ERCOT has already filed the bylaw amendments with the PUC for its expedited approval (50918). That should come by July 31, according to the docket’s procedural schedule. The amendments address the need and processes for teleconference meetings under social-distancing requirements related to the COVID-19 pandemic.

Demand, Temps on the Rise

June’s peak demand in ERCOT’s footprint came within 116 MW of last June’s peak, a sign that consumer demand and summer heat are nearing normal levels. The grid operator recorded a peak demand of 68,043 MW during the hour ending at 6 p.m. on June 8. Peak demand last June was 68,159 MW.

Gas-fired resources accounted for 40.9% of the energy produced during the month, with wind energy responsible for 23.34%. Coal resources provided 16.6% of ERCOT’s energy in June.

The grid operator was expecting a potential new weekend peak demand and a new all-time peak on Monday, July 13. ERCOT set a new all-time peak of 74.8 GW last year and has predicted a new mark of 75.2 GW this year, almost 1.5 GW less than staff predicted before Texas began locking down in March.

A heat wave continues to bake the Southwest and has brought triple-digit temperatures to much of Texas.

Monitor Says MISO Needs Higher Reserve Margin

MISO’s Independent Market Monitor said the RTO would be better served by an even higher planning reserve margin, two days after it recorded its first emergency of the summer.

Monitor David Patton said the grid operator should be using a 20% planning reserve margin requirement instead of the current 18% requirement that was in place when it called a maximum generation event on July 7. MISO’s planning reserve margin has climbed steadily in recent years; in 2017, it was just under 16%.

Speaking during a Market Subcommittee teleconference Thursday, Patton said part of the problem is MISO does not assume that planned generation outages and derates occur in the summer months.

But MISO is wrong there, he said.

Had it accounted for historical planned and unreported summertime outages, MISO would find its 18% margin requirement would look more like 11%, Patton said. If the RTO only included load-modifying resources that have lead times of two hours or less, that margin would fall to 8%, he said.

MISO currently allows LMRs with lead times as long as 12 hours to participate in its capacity market. The RTO recently filed with MISO Offers Concession on LMR Capacity Credit Plan.)

Patton said he would be “comfortable significantly reducing LMR accreditation to a two-hour” notification time. He said LMRs with six-hour notification needs provide “almost no reliability value” and wondered why they were being treated comparably with more valuable resources.

“It is the case that MISO has made improvements to notify LMRs to be ready ahead of time. And that’s good. But it’s still the case that MISO cannot see emergencies that far in advance,” he said.

Patton said excluding planned outages from reserve margin planning and accrediting long-lead LMRs contributes to the footprint’s tight conditions.

“We’re not as adequate as we think we are,” he said. “I think we’re adequate for this summer, but improving how we accredit capacity and price shortages will be increasingly important.”

Patton also said MISO needs higher pricing during shortages, especially as more intermittent resources are introduced into the resource mix.

“I’m not sure that we need new [market] products as much as we need really good shortage pricing,” he said.

Another Emergency Declaration

The Monitor’s recommendations were delivered as much of MISO Midwest was gripped by a persistent heat wave.

The high temperatures prompted MISO to issue a maximum generation emergency about 1-5:30 p.m. July 7 for its Northern and Central regions.

MISO reserve margin

LMPs at the Michigan hub exceeded $400/MWh on July 7 and neared $700/MWh around 3 p.m. Thursday. MISO’s peak load topped out at just over 114 GW on Thursday. The RTO had planned for a 120-GW peak that day.

MISO first issued a hot-weather alert and capacity advisory on July 1 and a conservative operations declaration beginning July 6. Conservative operations — where MISO requests that all transmission and generation outages be put on hold, if possible — were in effect through Friday.

MISO imported capacity from PJM during the July 7 emergency, even as the PJM region was also experiencing stifling heat.

Patton said MISO is mostly saved from capacity deficiencies during hotter-than-normal weather combined with low wind output by its “substantial” import capability from its footprint’s neighbors. He said imports are “utilized to avoid shortages in all the hottest conditions.”

He also reminded stakeholders that MISO still has a “theoretically flawed” capacity market where demand doesn’t set capacity’s reliability value. MISO’s vertical demand curve causes resources to prematurely retire, he said.

Patton also noted that MISO had several warm days with air conditioning demand in March and April. He said spring load would have been slightly higher than average but for the languishing demand introduced by COVID-19 pandemic-related lockdowns.

MISO executives said they will prepare data on and a review of the July 7 emergency event for the Reliability Subcommittee meeting July 30.
