Duke: NC Outages from Attacks May Last Until Thursday

More than 33,000 customers remained without power Monday afternoon in Moore County, N.C., following apparent attacks on two of Duke Energy’s (NYSE:DUK) substations over the weekend, and the company said some customers may not see their electricity restored until Thursday.

The outages began near the town of Carthage about 7 p.m. Saturday. They “shortly thereafter … spread to the greater majority of central and southern Moore County,” Sheriff Ronnie Fields said in a press conference Sunday afternoon. At the height of the outages, more than 45,000 customers had lost power, Duke said in a press release on Sunday; the utility’s outage map has been updated since then to reflect the restoration of some customers as crews work in 24-hour shifts, Duke confirmed to RTO Insider.

‘Pretty Sophisticated Repair’

Crews and sheriff’s deputies investigating the outages discovered “extensive damage” to two substations. Fields said the deputies found evidence indicating that firearms had been used to disable the facilities with “multiple shots” fired by attackers who “knew exactly what they were doing.” Duke said parts of the substations had been damaged “beyond repair,” requiring technicians to completely replace the affected equipment.

Duke spokesperson Jeff Brooks said at Sunday’s press conference that “we are looking at a pretty sophisticated repair with some fairly large equipment,” and that Duke is “pursuing multiple paths of restoration [to] restore as many customers as possible, as quickly as possible.”

The county implemented a 9 p.m.-5 a.m. curfew Sunday night “to best protect our citizens and … businesses of our county,” Fields said. Additionally, most county operations were shut down on Monday except emergency services, along with limited transportation for medical needs. County Manager Wayne Vest said that the county would probably be working “a skeletal operation” through Monday and hope to “get back up to full speed” by Wednesday.

“We faced something [Saturday] night here in Moore County that we’ve never faced before, but I promise you we’re going to get through this, and we’ll get through it together,” Fields said at the press conference. “We’re very united here in Moore County, and we’re not going to let this hold us back, and I can promise you, to the perpetrators out there, we will find you.”

No Known Motivation

Law enforcement has not publicly identified any culprit or motivation for the attacks so far. Fields said that “every available officer” in his office is doing “what we can to try to determine what happened,” with municipal and state officials contributing to the effort, along with the FBI.

The Electricity Subsector Coordinating Council (ESCC) said in a statement Monday that it was “working closely with … law enforcement officials” in their investigation into the attacks. Participants in an ESCC-hosted conference call Monday night included FERC Chairman Richard Glick; Brandon Wales, executive director of the Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency; and Deputy Energy Secretary David Turk.

The ERO Enterprise has also mobilized in response to the incident. SERC Reliability CEO Jason Blake said in a statement that the regional entity is “in close coordination” with Duke, NERC, federal agencies and “appropriate industry members across our 16-state footprint [so that] information is shared as it becomes known and that utilities across our footprint are in a heightened security posture.”

Asked about online rumors that the attacks were meant to shut down a local drag show that was planned to occur Saturday night, Fields said that while “anything’s possible,” the office had “not been able to tie anything back” to the show. Calling the perpetrators “cowards,” he acknowledged that no person or group had stepped forward to take responsibility for the attacks, adding that while the targeting of the power grid “wasn’t random,” he could not say at this point whether the incident should be considered an act of domestic terrorism.

The suspected connection to the drag show was apparently strengthened by a series of provocative Facebook posts by Emily Grace Rainey, a self-proclaimed conservative activist living in Moore County who served in the U.S. Army before resigning amid an investigation of her participation in the Jan. 6, 2021, attack on the U.S. Capitol.

Before the outage began, Rainey had posted the contact information of the drag show’s sponsors, adding, “You know what to do.” After the outage started she wrote, “The power is out in Moore County, and I know why,” later posting a picture of the theater where the show was supposed to be held with a caption saying, “God will not be mocked.”

However, Fields said on Sunday that while deputies had interviewed and “had a word” with Rainey, the lead “turned out to be nothing.” He urged citizens not to post false information online, reminding listeners that it “takes time for us to run that down.”

History of Physical Security Threats

The idea of domestic terrorists attacking the power grid has gained credibility in recent years, especially following the announcement in February that three men had pleaded guilty to planning to damage substations with high-powered rifles. (See FBI: Conspirators Planned Grid Attack to Start Race War.) According to their confessions, the men hoped to spark “confusion and unrest” that would lead to a civil war, inspired by “racially or ethnically motivated violent extremist views.”

The tactics of Saturday’s incident also resemble those of the 2013 attack on Pacific Gas and Electric’s Metcalf substation near San Jose, Calif. In that event, whose perpetrators have never been identified, snipers fired an estimated 150 rounds at transformer radiators in the facility, hitting 10 of the 11 targets and resulting in the loss of about 52,000 gallons of cooling oil. (See Substation Saboteurs ‘No Amateurs’.) The attackers are also believed to have cut underground fiber optic cables near the substation, temporarily disabling phone and 911 service for the area.

Physical security for bulk electric system facilities is addressed in NERC’s Critical Infrastructure Protection (CIP) reliability standards, most notably CIP-014-3 (Physical security), the first version of which was introduced two years after the Metcalf attacks. Asked about security preparations at Duke’s substations on Sunday, Brooks said that “we take security extremely seriously” and that the utility was confident its security requirements were in place at the affected facilities.

“We understand that we’re critical infrastructure, and so we do incorporate multiple layers of security at all of our facilities and across our system to help protect the grid and … restore power when we have disruptions,” Brooks said. “We can’t provide specific information on security measures at a critical facility, but I can say that certainly we’re one of the most highly regulated industries in the country. There’s a lot of protocols around security that we follow, and we believe we followed those in this case.”

FERC Approves PJM Tariff Revisions for SAA Cost Allocation

FERC on Friday approved revisions to PJM’s tariff that assign the full costs of constructing transmission upgrades necessary for the installation of 7,500 MW of offshore wind in New Jersey to the state (ER22-2690).

The commission affirmed that the proposal conforms with Order 1000’s State Agreement Approach, which permits a state to take on the cost of transmission upgrades for generation projects supporting their public policies. The order allows the installation of an estimated $1.07 billion in grid upgrades to go forward.

FERC found that the tariff revisions would not result in costs being passed to customers outside New Jersey, a concern raised by Long Island Power Authority; New York Power Authority; and three merchant transmission facilities (MTFs), Neptune Regional Transmission System, Linden VFT and Hudson Transmission Partners, which filed a protest as the “MTF Parties” on Oct. 31. (See NY Stakeholders Balk at NJ OSW Cost Allocation.)

The groups argued that the proposed language left open the possibility that a portion of the costs could be indirectly passed on to New York customers through border rate service. They called for more explicit clarifications to be added to preclude that possibility and specify that costs can only be applied to firm point-to-point transmission service.

The commission ruled that PJM adequately addressed those concerns in the revisions, as well as in a settlement agreement that FERC approved the same day between the RTO, its TOs and the MTF Parties, pertaining to point-to-point border rates (ER19-2105).

“We do not agree with MTF Parties that the crediting under the border rate revenue requirement, as proposed in the border rate settlement, may still result in New Jersey SAA project costs being passed through to entities that did not voluntarily agree to pay for those costs,” the commission said. “The border rate settlement specifically provides that the revenue requirement will not include the costs of state agreement public policy projects. Passing on such costs would violate that term.”

The order was unanimously approved, though Chair Richard Glick did not participate. Commissioner James Danly wrote in a concurring statement that he believes the order addresses the MTF Parties’ concerns, but if they continue to believe there are issues with the approved revisions, they should seek a rehearing.

“To the extent to which the MTF Parties find that the language set forth in today’s order fails to allay their concerns, they should pursue rehearing by citing the specific tariff language to which they object and should enumerate the specific misinterpretations that they fear, along with the consequences of those misinterpretations,” he wrote.

The FERC approval now allows for PJM and the New Jersey Board of Public Utilities to shift their attention to filing amendments to the SAA. During a Nov. 4 meeting of the PJM Transmission Expansion Advisory Committee, Assistant General Counsel Pauline Foley said filing those amendments with FERC first required the approval of a cost allocation methodology from the commission.

Solar Industry Slams Commerce Decision Extending Solar Tariffs

Criticism from the U.S. solar and clean technology sector was almost instantaneous on Friday after the Commerce Department issued a preliminary decision that could extend tariffs on solar cells and panels imported from 22 companies in Cambodia, Malaysia, Thailand and Vietnam.

According to a Commerce Department investigation — begun in February after a complaint from Auxin Solar, a U.S. manufacturer — those companies are using key components from China in a way that allows them to circumvent existing tariffs, called anti-dumping and countervailing duties (AD/CVD).

Four companies — New East Solar in Cambodia; Hanwha Q Cells and Jinko Solar Technology in Malaysia; and Boviet Solar Technology in Vietnam — were found not to be circumventing and are exempted from the duties. Other companies can avoid the tariffs through a certification process.

Abigail Ross Hopper, CEO of the Solar Energy Industries Association (SEIA), called the preliminary decision “a mistake we will have to deal with for the next several years.”

While “Commerce didn’t target all imports from the subject countries,” Hopper said, “this decision will strand billions of dollars’ worth of American clean energy investments and result in the significant loss of good-paying, American, clean energy jobs.”

Following industry outcry about the investigation, President Biden ordered a two-year moratorium on AD/CVD on solar cells and panels from the four countries, which will end in June 2024. But, Hopper said, even that breathing space “is simply not enough time to establish manufacturing supply chains that will meet U.S. solar demand.”

Gregory Wetstone, CEO of the American Council on Renewable Energy, also called the decision “a major step backward.”

The preliminary decision “creates new challenges that threaten to undermine Biden administration efforts to address climate change and accelerate the clean energy transition,” Wetstone said. “The Commerce Department appears to be doubling down on constricting solar availability and imposing massive new red tape with certification requirements that could further chill the industry and thwart the administration’s clean energy objectives.”

Others, like JC Sandberg, interim CEO of the American Clean Power Association, argued that the tariffs would undercut efforts to build out a domestic supply chain for solar, including the tax credits for solar and other clean energy manufacturing in the Inflation Reduction Act.

“American solar companies are making critical 2024 procurement decisions now, and today’s decision casts greater uncertainty about the future of the solar industry in the U.S. that could lead to higher electricity bills,” Sandberg said.

Not all reactions were negative. Michael Stumo, CEO of the Coalition for a Prosperous America, a nonprofit focused on trade issues, welcomed the decision as “an important win for the rule of law” and criticized Biden’s tariff moratorium.

“At a time when American manufacturers are investing billions of dollars to boost domestic production as a result of the Inflation Reduction Act, it is unconscionable that the White House wants to continue to give Chinese manufacturers a pass for illegally violating U.S. trade law to the detriment of American companies and American workers,” Stumo said.

The Commerce Department will be verifying the information in the preliminary decision and accepting comments from industry stakeholders, according to a Friday press release. A final decision is now scheduled for May 1, 2023.

‘Minor or Insignificant’

The Commerce Department first slapped tariffs on Chinese solar panels in 2012, siding with U.S. solar companies that argued that Chinese companies, heavily subsidized by the Chinese government, were undercutting domestic manufacturers and dumping cheaper panels in the U.S. market. Tariffs — from 31 to 250% at the time — would level the playing field and spur the buildout of a domestic supply chain, they argued.

Ten years on, solar manufacturing has migrated to Cambodia, Malaysia, Thailand and Vietnam; the solar industry and federal government continue to fight over solar trade policy, and the U.S. still does not have a comprehensive domestic supply chain. In 2018, former President Donald Trump expanded the Chinese tariffs to the four Southeast Asian countries, where solar panels are manufactured using Chinese components. Biden decided in February to continue the tariffs, later adding the two-year moratorium.

Arguments for and against the current decision hinge on differing perceptions of the manufacturing processes occurring at solar companies in the four countries, the extent of Chinese involvement and the U.S. solar industry’s ability to build out a comprehensive domestic supply chain.

According to industry analysts ClearView Energy Partners, the preliminary decision reflects the Commerce Department’s “protectionist leanings.” The decision generally concludes “that the value of the merchandise produced in China before it was sent to the Southeast Asian nations represented a ‘significant portion of the total value’ of the final product exported to the U.S.,” ClearView said in a research note released Friday.

Further, Commerce said, the processes for assembling and completing cells and panels in these countries were “minor and insignificant,” according to ClearView.

As outlined in the preliminary decision, Commerce based its findings on information gathered in response to questionnaires sent to companies in the four countries. Companies that did not provide the information requested on time and “failed to cooperate to the best of their abilities” were subject to an “adverse inference” that they were circumventing the AD/CVD tariffs.

But SEIA’s Hopper said Commerce had “elected to exceed its legal authority. As a basic fact, solar cell and module manufacturing greatly exceed the anticircumvention statute’s ‘minor or insignificant processing’ limitation.”

George Hershman, CEO of SOLV Energy, a utility-scale solar installer, also argued that the processes being penalized in the decision are the same as those the IRA seeks to incentivize. The preliminary decision is “inherently hypocritical” and “doesn’t pass the common sense test,” Hershman said.

“This ruling will further constrict a challenged supply chain and undercut our ability to fulfill the promise of the Inflation Reduction Act,” he said.

ClearView agreed the decision “could add to solar product trade risk.”

IRA tax incentives could “encourage domestic manufacturing, but our review of solar products demand and recently announced U.S. investments suggests the U.S. market is likely to remain partially reliant on imported solar modules and heavy reliant on overseas solar supply chains after the AD/CVD might take effect,” ClearView said.

New solar installations in the U.S. hit 18.9 GW in 2021, ClearView said, and the U.S. Energy Information Administration expects that number to more than double, to 39.7 GW in 2023.

Exceptions 

In a report released in August, SEIA predicted that building out a full domestic supply chain for all solar components, from polysilicon wafers to inverters, could take five years or longer. The group is targeting a U.S. supply chain capable of producing 50 GW of “domestic solar manufacturing capacity” by 2030.

According to the report, “the United States currently has no domestic solar ingot, wafer or cell manufacturing capacity and only modest capacity to produce solar modules, inverters and trackers. … Practical timelines for siting, permitting, constructing and commissioning new factories [will] influence how quickly domestic manufacturing can scale.”

Ingots are blocks of polysilicon, which are then sliced into the superthin “wafers” that go into the solar cells used to produce panels. According to industry analyst Bernreuter, seven of the top 10 polysilicon producers in the world are Chinese companies.

But another industry analyst, who requested anonymity because he is not authorized to speak publicly, said that the details of the decision provide a range of loopholes for companies to avoid the tariffs once Biden’s moratorium expires.

First, the exclusion of Hanwha and Jinko, both major U.S. suppliers, provides some certainty for the industry, he said.

The decision also excludes solar cells and panels made with wafers not specifically produced in China, even if the silicon ingots they are sliced off of are. “That means that all the … production [of wafers] that is online and coming online in Southeast Asia can be made into cells that are not subject to duties,” he said.

Another big loophole is the exclusion for cells and panels where four of six key components — silver paste, aluminum frames, glass, backsheets, ethylene vinyl acetate (EVA) sheets and junction boxes — are not made in China. Silver paste is a conductive material used to improve electricity production in solar panels, and EVA sheets are used to “encapsulate” and protect solar cells in panels.

“If you have four of the six … made outside of China, no duties. That’s not going to be hard to comply with,” the analyst said. “You can make aluminum frames anywhere; you can make glass a lot of places; backsheets, EVA; there’s no reason you have to make this stuff in China. … And then suddenly — boom — all of those modules aren’t subject to duties.

“This was a much better decision for the industry than people may realize,” he said. “The fine print here is really positive for us to continue to have module supply for the next few years.”

But, the analyst cautioned, building out a U.S. supply chain, especially for ingots and wafers, will face challenges. Setting up the new factories will be capital intensive, “and you need somebody who’s got the know-how to do them,” he said. “That ingot and wafer knowledge is now concentrated in Asia, so you have the same problem.”

NYISO Investigating Tariff Changes to Improve Interconnection Processes

RENSSELAER, N.Y. — NYISO officials said Wednesday they will begin stakeholder discussions early next year on revising the interconnection process to make it more efficient, calling it one of their top priorities for 2023.

Zach Smith, vice president at NYISO, told the Management Committee that the ISO is considering a “queue window-based approach,” where each stage of the study would be more meaningful and potentially binding.

The new approach would replace the current three-step study structure, which includes an optional feasibility study and a non-binding system reliability impact study (SRIS) before the facilities study, which results in binding cost allocations.

Smith said the ISO envisions a “clustering approach” where projects are put into a study together to evaluate their joint impact. Smith emphasized, however, that this was simply a preview of what will be discussed with stakeholders and that nothing is settled.

Smith said the additional changes would require tariff revisions and FERC approval, unlike changes the ISO has already made — adding interconnection support liaisons and project managers; improving the interconnection portal; streamlining the SRIS — and ones in process — developing templates to shorten SIS reports and improving handling of material modification requests. (See NYISO Identifies 35 Projects for Narrowed SRIS Scope.)

The ISO expects to begin discussions in the MC, the Transmission Planning Advisory Subcommittee and Electric System Planning Working Group as soon as January and no later than February. “We do not intend to hold up on any improvements waiting” for an order from FERC’s June Notice of Proposed Rulemaking on interconnection generator interconnection procedures and agreements (RM22-14), Smith said. (See FERC Proposes Interconnection Process Overhaul.)

Smith said NYISO is acutely aware of potential tradeoffs stemming from pursuing faster methodologies but is committed to ensuring that project reliability is never sacrificed.

“Do you want speed or do you want flexibility?” Smith said. “One will have to be sacrificed for the other.”

Smith added that it is important for FERC to maintain “independent entity variations” enabling RTOs to tailor solutions to their own regional problems.

CEO Rich Dewey said that the ISO is committed to addressing both the effectiveness of these processes and the customer communication around them. Dewey told stakeholders he understands trade-offs will occur as further changes are made to find the “sweet spot” between flexibility and efficiency.

Mark Reeder, representing the Alliance for Clean Energy New York, commended the ISO for its continued focus on improving the interconnection process: “That’s greatly appreciated.”

Texas Politicians Assert Themselves in PUC’s Market Redesign

Texas lawmakers have jumped into the middle of the Public Utility Commission’s effort to redesign the ERCOT market, saying they are concerned the PUC’s proposals don’t do enough to incent investment in new gas-fired generation.

The commission had been quietly working with consultants behind closed doors to develop new market designs that would protect ERCOT against a repeat of 2021’s disastrous winter storm. But when the PUC unveiled the results of its work last month, it quickly drew pushback from the market and energy experts over its close resemblance to capacity markets. (See Proposed ERCOT Market Redesigns ‘Capacity-ish’ to Some.)

The lead proposal, a performance credit mechanism (PCM) that would require load-serving entities to buy performance-based credits from generation resources that meet reliability standards, has never been tried by a U.S. grid operator. The PUC has asked ERCOT stakeholders and the general public to provide feedback on the PCM and five other market designs by Dec. 15.

However, Texas lawmakers, who see adding more gas-fired, or dispatchable, generation as the solution to the problem (They define dispatchable resources as those not “controlled primarily by forces outside of human control.”) have stepped into the fray.

On Wednesday, Lt. Gov. Dan Patrick, who presides over the state Senate and has tremendous influence over its legislation, unveiled his list of priorities for the Texas Legislature’s 88th session, which begins Jan. 10. They include improving the grid’s reliability; he threatened to keep lawmakers in Austin until they pass legislation that encourages gas-fired power plants to be built.

“Whether it is incentivizing them; whether it’s building them; whatever the plan is, I personally cannot see myself leaving this building knowing that another [winter storm] can happen,” Patrick, who called renewable energy “a luxury,” said during a press conference. “We have to level the playing field so that we attract investment in natural gas plants.”

Observers have noted that would put Patrick at odds with Gov. Greg Abbott and Peter Lake, his handpicked commission chair. Both have said the grid is better than ever because of weatherization, coordinated communication and other operational changes put in place at the end of last year.

The bipartisan Senate Business and Commerce Committee followed up Patrick by sending a letter Thursday to the PUC’s commissioners, urging them to stick to the directives in Senate Bill 3. The omnibus bill, passed last year following the winter storm that almost brought down ERCOT’s grid and left millions of Texans in the dark for days, called for “adequate incentives” for dispatchable generation. It also instructed the PUC to incentivize that dispatchable generation by establishing a reliability standard for the market and using that standard to develop or procure a new ancillary or reliability service for the generators. (See Abbott Signs Texas Grid Legislation into Law.)

The committee had already heard from the PUC, ERCOT and stakeholders, having held a hearing on the plan Nov. 17. It said the testimony that day indicated the PCM was an “administratively complex and novel concept” that would “deter new investments in the ERCOT market until it is fully in place.” (See Legislators, Stakeholders Pan Proposed ERCOT Market Design.)

“By the commission’s own admission, [that] could be several years down the road,” committee members wrote. “There is significant concern the proposals being considered by the commission … not only failed to meet the directives clearly stated in SB3, but more importantly will not guarantee new dispatchable generation in a timely and cost-effective manner. …

“It is not in the best interest of our constituents to support any proposal that further delays investments in new dispatchable generation, and the commission should carefully consider the unintended consequences of any type of proposal that creates more uncertainty for market participants.”

The committee directed the PUC to define ERCOT’s reliability goals before moving forward with any “significant” market redesign and to evaluate creating a new market-based ancillary or reliability service to meet reliability standards.

“Any holistic market design change, including the PCM, that goes beyond the scope of SB3 should not be adopted by the commission without further consultation with the legislature,” the committee said in concluding its letter.

The hits could keep coming. On Monday, the House of Representatives’ State Affairs Committee will hold a public hearing to review the proposed market changes.

The PUC seemed unfazed by the legislative comments. It still plans to present a final recommendation to the legislature next year before allowing ERCOT to begin the implementation process.

A spokesman said the commission will develop a reliability service, “as we’ve said since the beginning of this process.”

“The [PUC] published multiple options for consideration and eagerly awaits public comments on all options,” Rich Parsons said in an emailed statement. “Once the commission holds a vote on a preferred reliability service, we will present it to the legislature next session.”

“The PUC should take this legislative brushback of the chairman’s preferred solution very seriously. It’s a bad idea to tick off the folks who approve the commission’s budget, appointments and headcount,” Alison Silverstein, an energy consultant with experience at both the PUC and FERC, told RTO Insider on Friday.

She said the PCM proposal is “barely articulated, poorly analyzed, ill-supported and precedent-free, with little evidence that it will produce new gas plants.”

“I wouldn’t risk the Texas economy and energy affordability for [the PCM],” Silverstein said.

She put in a plug for the backstop reliability service, one of the other five designs. The ancillary service would meet specific reliability needs not met by ERCOT’s real-time and ancillary service markets during high uncertainty periods. Silverstein said it would act as an insurance policy that would better manage plant retirements.

Stoic Energy principal Doug Lewin said that building new gas plants will only lead to higher customer bills.

“If you want to lower bills, you need to integrate more renewables and increase energy efficiency,” he tweeted, noting that a consultant for the PUC has shown that high renewable generation reduces energy costs by 20%.

“No one thing will solve any, much less all, of these problems,” Lewin added. “Unfortunately, some policymakers are trying to solve a different problem. They don’t like renewables and want more gas plants. That won’t solve any of the problems.”

MISO: 200 GW in New Capacity Necessary by 2041

CARMEL, Ind. — MISO said last week its members may need to build 200 GW in new installed capacity by 2041 to meet reserve requirements and achieve renewable targets and emissions-cutting goals, according to the RTO’s annual regional resource assessment.

The grid operator used this year’s report, which draws on members’ public generation plans and MISO’s own capacity expansion estimates, to repeat warnings of continuing capacity shortages and plead for more controllable generation. Staff said members may need to construct more than 100 GW of new capacity within the next 10 years alone to meet “publicly announced plans and goals in a reliable manner.”

After the inaugural assessment in 2021, MISO said it would need to add 140 GW of new capacity over the next two decades to meet state carbon-reduction targets while also maintaining reliability. Carbon reduction goals have only become more aggressive in the last year, with utilities frequently revising net zero goals. (See MISO Resource Assessment: 140 GW Needed Within 20 Years.)

This year, MISO focused on accredited capacity numbers. Although it expects members to add 30 GW of net installed capacity by 2041, it said accredited capacity will be at least 10 GW lower than what is available today.

The RTO projects members will likely need to add 47 GW in accredited capacity above the 141 GW of planned and accredited existing resources it expects to have in 20 years. It has approximately 162 GW in total accredited capacity today.

MISO said it will likely approach 30% of its annual energy coming from renewables within five years, with penetration levels increasing by about 10% every five years.

Its modeling “indicates a continued near-term capacity risk, highlighting the urgent need for coordinated resource planning and additional investment.” Staff stressed that the assessment captures a snapshot in time that relies on publicly available resource planning and isn’t necessarily MISO’s future. They emphasized that MISO members do not produce “detailed” resource plans on a 20-year time horizon.

“In the absence of a coordinated transition plan, having a holistic assessment of our entire operating region is important for our members, policymakers and MISO as we all work to anticipate and manage the complex issues facing our industry,” CEO John Bear said in a Wednesday press release accompanying the report.

According to the report, wind and solar generation will serve 60% of MISO’s annual load by 2041, reducing emissions by nearly 80% relative to 2005 levels. The RTO said that generation mix will “sharply increase the complexity of reliably operating and planning the system.”

The footprint will “have a much greater need for controllable ramp-up capability,” MISO said. It said its short-duration ramp needs will increase three-fold from current levels by 2031, and four-fold by 2041.

MISO also said that by 2031, it will encounter resource adequacy risks in all seasons, not just summer. The grid operator said the risk will mostly be concentrated in the evenings when solar generation tapers off and wind generation is still ramping up.

The RTO found that as more solar capacity is added to the system, the capacity contribution of solar generation “is forecast to decline rapidly,” while wind generation’s contribution remains stable with additions.

“As the MISO region rapidly transitions to a decarbonized fleet, the system will become more interconnected and interdependent,” Jordan Bakke, director of strategic insights and assessments, said. “The task of resource planning is becoming more complex and having a shared understanding of future trends and risks is necessary to ensure reliability.”

MISO has a staggering amount of proposed capacity in the interconnection queue after fielding in September a record 171 GW of proposed renewable generation and storage projects from 956 requests. (See MISO Insists it can Handle Record-setting Interconnection Queue.)

The rub is MISO’s supply of accredited capacity. And while capacity increases, its share of on-demand capacity is drying up.

During a Nov. 10 stakeholder workshop, policy studies engineer Hilary Brown said members are largely planning investments in solar and wind capacity as they schedule more coal generation retirements.

“A one-for-one megawatt replacement is likely not sufficient,” Brown said of members’ plans.

She said MISO expects the near-term capacity risk to continue with the growing need for flexible resources to reinforce intermittent resources.

The RTO’s system simulation showed it will likely need a yet-unknown combination of low-emission, high-capacity grid-enhancing technologies by 2030, including carbon capture and sequestration, small modular reactors, green hydrogen and long-duration energy storage.

Stakeholders have pressed MISO to provide a megawatt value of how much new storage it might need over the next 20 years.

MISO Charts Course on Capacity Auction’s Sloped Demand Curve

CARMEL, Ind. — MISO is releasing preliminary design details of a sloped demand curve in its capacity auction. Staff plans to use its planning reserve margin requirement as a middle point and adding and subtracting incremental amounts of capacity, measured by expected unserved energy.

“It’s going to be convex shaped,” Mike Robinson, principal adviser of market design, told the Resource Adequacy Subcommittee Wednesday.

Robinson said MISO doesn’t yet have exact values associated with the demand curve.

“We have preliminary numbers, and we’re assessing them to make sure they pass the smell test and that they’re reasonable,” he said.

Reliability will be “foremost” in designing the curve’s shape, Robinson said. He noted MISO wants a demand curve that encourages reliability while valuing capacity at market prices. A capacity glut would render sloped curve prices nil, Robinson said.

Independent Market Monitor David Patton said a sloped curve can prevent premature resource retirements and will raise revenues for most utilities. He said the curve will also “reduce financial risk and the volatility associated with overbuilding and underbuilding of capacity.”

“You’ve all heard me talk about this for a decade or more,” Patton told stakeholders.

The Organization of MISO States has largely endorsed MISO revising the vertical demand curve currently used in MISO’s planning resource auction (PRA). (See State Regulators Endorse New Demand Curve in MISO Capacity Auction.)

OMS Executive Director Marcus Hawkins said support was “near unanimous.”

Some stakeholders have said that setting a demand curve is challenging because utilities place differing value on additional capacity.

MISO said that to formulate a sloped demand curve, it will need to run analyses using the net cost of new entry (CONE), or an approximated revenue from capacity payments. To do this, the grid operator is proposing to use three years’ worth of historical data to calculate inframarginal rents, the money used to cover generators’ fixed costs. Net CONE will be calculated by subtracting inframarginal rents from CONE and using them to inform the curve’s final shape.

Robinson said staff is trying to bend the curve in a way that supports net CONE over the long run.

Multiple stakeholders cautioned that inframarginal rents are rooted in market ambiguity and could set off lengthy stakeholder disagreements over what amount is appropriate.

A sloped curve will also have MISO adding what it calls an “advanced” fixed resource adequacy plan (FRAP) option.

Robinson said MISO isn’t planning on changing any existing participation options for market participants; they can still opt out of the auction, make a FRAP, self-schedule resources, or purchase from the PRA.

“This is just another option here we want to make available,” he said.

An advanced FRAP will require market participants to get their relevant regulator’s approval, make a showing that they can meet their load obligations a month ahead of the auction, and commit to not taking offers in in the auction for a minimum of three consecutive years. Under an advanced FRAP, load-serving entities could sell their excess capacity provided it they have a certain, yet-undetermined percentage of capacity beyond their requirement.

Robinson said MISO won’t allow partial advanced FRAPs as it does with run-of-the-mill FRAPs. “You’re either fully in or fully out,” he said.

Robinson said allowing a partial advanced FRAP would complicate the auction’s algorithm. He also said a minimum commitment will discourage load-serving entities from “toggling in and out of the auction.”

MISO will take stakeholder opinions on its early proposal through the end of the year.

A sloped demand curve in the capacity auction was top of mind during a late summer stakeholder idea exchange.

Bill Booth, a consultant to the Mississippi Public Service Commission, said he didn’t see why a downward sloping demand curve is en vogue again. He said MISO’s circumstances — being overwhelmingly comprised of vertically integrated utilities — haven’t changed since a sloped demand curve was last contemplated and shot down five years ago. He said the RTO’s excess capacity drying up is the only thing that’s different.

“There’s plenty of renewable generation trying to tie into the system, so I don’t think we need to promote that,” Booth said. “That’s clear from the interconnection queue … but it might not be the generation we need for our circumstances.”

He said decisions on fuel mixes are made at the state level and its naïve to hope that a demand curve’s prices will spur more dispatchable resources. Booth suggested MISO’s planning reserve margin requirement could be tailored to require a certain amount of dispatchable generation.

Hawkins argued that a capacity shortage isn’t MISO’s only issue. He said clearing prices in recent resource auctions have become increasingly volatile.

Julie Fedorchak, the North Dakota Public Service Commission’s chair, said the RTO’s capacity market “desperately” needs better market signals, and the demand curve is a tool toward improving them. She said that, candidly, she was “sick and tired” of some MISO members freeriding at the expense of her ratepayers.

MISO has committed to more frequent postings of preliminary capacity auction data. The grid operator will standardize the schedule of seasonal reserve requirements in zones to twice per month in mid-January.

The more frequent data shares are a response to stakeholders’ asking staff to publish more regular updates ahead of the auction on its supply estimates and requirements. (See “Stakeholders Ask for Data Improvements,” MISO Promises Stakeholder Discussions on Capacity Auction Reform.)

MISO Simpatico with Monitor’s 2022 Market Recommendations

CARMEL, Ind. — MISO says it “largely agrees” with its Independent Market Monitor’s five new market recommendations issued this year.

The IMM’s annual State of the Market report, released this summer, listed recommendations for promoting transmission reconfiguration plans, reducing out-of-market commitments, creating a future-looking dispatch model and ensuring MISO only pays for real load reductions. (See MISO Monitor Prescribes 5 New Fixes in Annual Market Report.)

The grid operator said it is actively working on three of the ideas, while the remaining two are on its list of five-year goals.

In reviewing the market performance in 2021, the Monitor said the RTO should:

  • work with its transmission owners to identify and implement economic transmission reconfiguration plans to better manage congestion;
  • evaluate and restructure its unit commitment process to reduce out-of-market commitments and ensuring make-whole payments;
  • develop a multihour, look-ahead dispatch and commitment model to better manage fluctuations in net load and decisions on when to use storage resources. Patton said, “as reliance on intermittent resources grows in MISO, the need to manage extraordinary fluctuations in net load will grow;”
  • improve rules around demand participation in energy markets so that MISO only pays for load reductions that occur; and
  • consider classifying load-modifying resource (LMR) curtailments as short-term demand in pricing models and the unit dispatch system.

The last recommendation stems from Patton’s observation that LMRs are allowed to set real-time energy prices long after emergency conditions have passed. He said that’s because of MISO’s extended locational marginal pricing (ELMP) model respecting resources’ ramp rates, which makes it impossible to replace a large volume of LMRs within a single dispatch interval.

Patton said the LMRs appear to be necessary and set prices “long after MISO’s resources are sufficient to replace them by ramping up.” He said that if MISO treats LMRs as an operating reserve demand in the ELMP model, it would eliminate the problem.  

MISO said it has yet to begin work on the second stage of its look-ahead commitment tool or categorizing LMR curtailments under short-term demand for pricing purposes.

Zhaoxia Xie, with MISO’s market design team, said staff may encounter some difficulty including LMR curtailments because short term reserves are priced systemwide or zonally, whereas LMRs are modeled at the more local nodal level. But she promised more evaluation on the issue Thursday during a Market Subcommittee meeting.

The RTO said it plans to augment its look ahead commitment tool in 2023 to improve commitment decisions. It said upgrades should reform its unit commitment processes with the added benefit of using storage resources to manage fluctuations in net load.

“This has been a hot topic between MISO and the IMM for a while,” Xie said. She said staff is constantly evaluating improvements in its commitments process.

The grid operator agreed that it could use more stringent rules and procedures for demand participation “to avoid unjust payments.” MISO said it may file tariff revisions with FERC after consulting with stakeholders.

Staff said they’ve been working since January with transmission owners to develop operating procedures for transmission reconfiguration. They will begin a reconfiguration process in 2023’s first quarter to reduce congestion costs.

MISO’s Tony Rowan said the procedure involves a market participant bringing a suggested economic reconfiguration to staff and relevant TOs, who will test the solution over 15 business days for reliability and economic impacts. If MISO and TOs agree the solution puts a dent in congestion without deteriorating system conditions, the reconfiguration plan will go into effect for an agreed-upon duration.

MISO also said it will maintain a public list of the footprint’s top 10 most economically impacted constraints.

MISO Proposes Review of Improvement Ideas’ ‘Parking Lot’

CARMEL, Ind. — MISO is proposing a biennial review to reduce its “parking lot” list of improvement suggestions, although some stakeholders are putting up resistance.

“We’d like to make sure that good ideas don’t go to the parking lot to linger indeterminately,” Laura Rauch, senior director of transmission planning, said during a Market Subcommittee meeting Thursday

MISO’s parking lot contains improvement ideas submitted to MISO through its issues-submission process. It has become a graveyard of shelved ideas, with some stakeholders complaining that their recommendations remain unaddressed. (See MISO Pledges Review of On-hold Stakeholder Ideas.)

The grid operator said it will clean up the parking lot and eliminate nearly 20 suggestions. In some cases, staff doesn’t have a record of the stakeholder that originally submitted the idea or its full description.

The grid operator said it will use “active,” “inactive,” and “closed” to label the idea list. “Closed” means MISO has no current plans to address the idea and i will fall off the list. Staff will work with stakeholders with inactive projects and determine their feasibility every two years.

Rauch pointed to a suggestion creating a universal resource participation model that has spent years in the parking lot. MISO doesn’t distinguish market participation models by intermittency, energy storage and demand response, leading Rauch to term the suggestion “aspirational” and suggest it should be closed. Stakeholders could always revive the idea by submitting it again to the RTO.

Rauch also said there’s some redundancy among the improvement recommendations.

“To me, this seems like another way MISO isn’t allowing stakeholders to decide when an item doesn’t need attention,” Clean Grid Alliance’s Natalie McIntire said.

Independent Market Monitor David Patton took umbrage with MISO’s move to close his suggestion that a virtual spread product be created in the day-ahead market. It would allow participants to specify the maximum congestion between two points they are willing to pay in a virtual transaction.

Rauch said in this case, staff last delivered a presentation on a virtual spread product in 2012. She said MISO has no plans to address the issue.

Xcel Energy’s Kari Hassler said she was concerned that the grid operator would put recommendations on the chopping block before it has completed its new market platform, which has been billed as being able to host more complex market products.

“We have a lot of projects that are pushed back and waiting in the wings until” MISO’s new market platform is finished, Hassler said.

MISO plans to roll out its day-ahead market on the new, modular market platform next year.

FERC Must Clarify MISO Transmission Funding Decision, DC Circuit Finds

FERC must better explain its 2019 decision to give MISO transmission owners unilateral authority to finance upgrades needed to interconnect new generation, the D.C. Circuit Court of Appeals ruled last week.

The proceeding was “the latest episode in a long-running dispute over how to fund upgrades to power lines,” Judge Justin R. Walker wrote in the decision issued Friday (20-1453).

The details in the case extend back to 2015, when Otter Tail Power filed a complaint with FERC challenging MISO’s policy of providing “direct” transmission owners with unilateral authority to decide whether to initially fund a needed upgrade — and later collect the costs from the interconnecting generator — or allow the generator to pay the costs up front. Otter Tail contended that while direct TOs exercised that privilege, operators of affected systems further downstream (“indirect” TOs) enjoyed no such option, resulting in differential treatment.

In a decision issued June 2015 (ER14-2464), FERC agreed with Otter Tail, but rather than extending the right of unilateral initial funding to TOs indirectly affected by an interconnection, it instituted a proceeding under Federal Power Act Section 206 directing MISO to either remove the unilateral option or explain why it shouldn’t. (See FERC: MISO Gen Agreement Allows Overcharging.)

The D.C. Circuit vacated FERC’s decision in 2018 in Ameren Services Co. v. FERC, saying the commission hadn’t considered complaints from Ameren and five other TOs that claimed the policy forced them to accept “risk-bearing additions to their network with zero return” and essentially act as “nonprofit managers” of network “appendages.”

The decision in Ameren “also held that FERC should have considered that its decision could force transmission owners to incur the financial risks of generator-funded upgrades without the opportunity for a profit,” the court noted in Friday’s ruling. “We declined to decide whether those enterprise-risk concerns required a particular result until FERC ‘developed a record by considering’ them.”

The case was then remanded to FERC, which in 2019 reinstated TO funding rights and extended them to indirect owners, a decision the commission affirmed the following year after a protest by the American Wind Energy Association (later renamed the American Clean Power Association (ACP)) (EL15-68, et al.). (See FERC Upholds MISO Self-fund Order, Glick Dissents.)

The commission had also made its decision retroactive, forcing the renegotiation of several generator interconnection agreements between 2015 and 2018. (See FERC OKs MISO Agreements Following TO Funding Ruling.)

‘Plausible Reasons’ for Concern

In the case decided by the D.C. Circuit on Friday, the ACP petitioned the court to review FERC’s orders, arguing that the commission had: failed to follow the Ameren decision’s command to “develop a record” of enterprise risks for TOs; acted in an arbitrary and capricious manner by giving TOs unilateral funding authority; and erred in making its 2019 decision retroactive.

The court dismissed the third argument, saying that its jurisdiction only extends to arguments that a party raised in a rehearing application to FERC, “unless there is reasonable ground for failure to do so,” points that ACP failed to argue.

Addressing ACP’s first argument, the court found that FERC did comply with the Ameren remand order.

There, we told FERC to ‘[develop] a record by considering’ the transmission owners’ enterprise-risk argument,” the court wrote. “That instruction suggested no particular briefing. Nor did it demand any additional evidence for a record that was already voluminous. Rather, it required nothing more than FERC ‘considering’ the enterprise-risk argument and putting that consideration on the ‘record’ for our review.

“On remand, FERC did just that: It considered the enterprise-risk argument and rendered a decision on its merits in the record for us to review.”

But the court did agree with ACP’s second argument, ruling that FERC’s decision to grant unilateral funding authority to all TOs failed to satisfy the “arbitrary and capricious” standard in the Administrative Procedures Act.

“Although FERC’s decision may ultimately prove to be ‘reasonable,’ it was not ‘reasonably explained,’” the court said.

The court noted that ACP did not “seriously dispute” FERC’s determination that, under the FPA, direct and indirect TOs should receive similar treatment with respect to upgraded funding. Instead, it argued that the commission violated the APA “by not adequately explaining its decision to solve that problem by giving unilateral funding authority to all transmission owners, rather than by denying unilateral funding authority to all transmission owners.”

The court said it agreed with ACP that FERC failed to reasonably explain its decision: “In particular, it gave short shrift to the petitioner’s concern that transmission owners might discriminate in favor of generators they own.”

In proceedings before FERC, the court noted, ACP provided “plausible reasons” for that concern, having pointed out that many TOs in MISO also own generators, providing a competitive motive to discriminate against other generators. And while FERC acknowledged that concern, it also concluded that concerns about potential discrimination did not outweigh the TOs’ enterprise-risk concerns.

FERC had argued that ACP did not “show why the ability of [generators] to challenge costs before the commission, a point on which the court relied, is inadequate to address any concerns with potential undue discrimination.”

But the court pointed to “something important missing from FERC’s orders: an assessment of the risk of discrimination and an explanation of why individualized proceedings provide generators with sufficient protection against that risk.”

In oral arguments, the court noted, counsel for intervenors supporting FERC “gave a relatively detailed assessment and explanation” of why the current regulatory regime should alleviate the risk of TOs giving preferential treatment to their own generation.

But FERC’s orders had failed to do that, it said.

“FERC had the chance to explain itself at two different steps in its proceedings,” the court said Friday. “It could have done so when it found that the unilateral funding option was not unjust or discriminatory, or later when it remedied the disparity between direct and indirect transmission owners in the Otter Tail proceeding. …

“We therefore remand for FERC to adequately explain its decision,” the court concluded. “But we do so without vacating FERC’s orders ‘because there seems to be a significant possibility that [FERC] may find an adequate explanation for its actions, and, in any event, it appears that the consequences of its current ruling can be unraveled if it fails to.’”
