CAISO CEO Lauds Transmission Planning Agreement

An agreement signed by California’s three electricity planning entities will help coordinate resource and transmission planning in California to better reach the state’s clean energy goals while maintaining grid reliability, CAISO CEO Elliot Mainzer told the ISO’s Board of Governors on Thursday.

The memorandum of understanding signed by the California Energy Commission, the state Public Utilities Commission’s and CAISO is a “new blueprint for our state” that provides for closer links between the planning processes of each party, Mainzer told the board in his monthly CEO briefing.

In California’s divided energy planning process, the CEC forecasts demand while the CPUC handles resource planning and CAISO deals with transmission needs.

“All of those are [gears] that need to be synchronized so that we can effectively onboard resources in California,” Mainzer said.

Outmoded planning was partly to blame for the state’s rolling blackouts in August 2020, CAISO, the CEC and CPUC said in an October 2020 report to the governor. (See CAISO Says Constrained Tx Contributed to Blackouts.)

The recent MOU was signed in December and posted by CAISO to its website Jan. 19. It supersedes a 2010 agreement that included only CAISO and the CPUC.

The MOU draws closer links between the CPUC’s Integrated Resource Planning (IRP) process, the ISO’s transmission planning process, including its conceptual 20-year outlook, the CEC’s Integrated Energy Policy Report (IEPR), which identifies the state’s energy needs and its activities under Senate Bill 100, which requires all retail customers to be served with 100% clean energy by 2045.

The MOU’s provisions include a requirement that the CEC, CPUC and CAISO “implement a joint work plan” on the CEC’s IEPR and SB 100 proceedings to align the three parties’ planning processes and maintain a flow of information between them. For example, under the new MOU the CPUC must incorporate the CEC’s longer-term forecasts into its IRP process, and CAISO has to supply the results of its transmission planning and interconnection studies to the CPUC for resource planning.

CAISO intends to “put that MOU into practice [this year] and … to transition from what I’ve characterized as sort of reactive transmission planning to much more leading and proactive transmission planning,” Mainzer said.

The ISO expects to release its annually updated transmission plan in May and to “identify the forward-looking zones where we think the next big resource batholiths will be opened up,” he said. “Our hope and expectation is that we’re going to be using [our] transmission planning … to do a much more effective job of shaping queuing and procurement … because we simply can’t be in the place of having to react and then we need 5,7, 10 years to get developed.”

“Transmission is a leading indicator of planning rather than a lagging indicator,” Mainzer told the board. “I’m hoping to be here by the end of this next year with a significant improvement in establishing those orders of operations.”

As an example of the need to improve the process, Mainzer cited CAISO’s efforts to deal with its “Cluster 14” queue of interconnection requests, which he detailed in his memo to the board.

“In April 2021, the ISO received 373 interconnection request applications totaling more than 50 gigawatts (GW) of renewable generation and more than 100 GW of energy storage in the Cluster 14 application window,” Mainzer said in the memo. “This was more than three times the average of 113 applications over the last decade, and more than double the previous high of 155. Because of the challenge for the transmission owners and the ISO to process that many applications, the ISO extended the phase 1 study process by a full year.”

At least 160 of the applications are moving to phase 2, and “that number may yet grow to more than 200 projects representing more than 67 GW, since a number of interconnection customers are still in the final validation process.”

The next group of interconnection requests, Cluster 15, could generate 300 new applications by April, putting additional strains on transmission planners, Mainzer wrote.

“The excessive number of applications also provides even more impetus to move forward with overhauling our interconnection process in keeping with the objectives of the recently signed MOU with the CPUC and the CEC to focus on prioritization through alignment of state resource planning, ISO transmission planning, procurement processes, and the interconnection process,” he said.

Senate ENR Committee Grills Turk on IIJA Implementation

A political war is looming over the interpretation and implementation of both the Infrastructure Investment and Jobs Act and the Inflation Reduction Act, with Sen. Joe Manchin (D-W.Va.), a key architect of both laws, attacking the White House on its efforts to circumvent what he sees as their clearly stated congressional intent.

“The United States has an all-of-the-above energy policy that supports using all of our God-given resources in the cleanest way possible,” Manchin said Thursday in his opening remarks at a Senate Energy and Natural Resources Committee hearing on the Department of Energy’s implementation of the IIJA. “That’s how we shore up energy security, achieve energy independence, while also addressing climate change.

“It is my intention to make sure that these laws are implemented swiftly, effectively and in line with that clear congressional intent, which I can assure you, this administration doesn’t seem to want to do, but we’re going to make sure they do it,” said Manchin, who chairs the committee.

Manchin’s opening salvos came as Deputy Energy Secretary David Turk faced the committee’s first meeting of the 118th Congress to report on DOE’s progress in rolling out the new programs funded by the IIJA. Keeping largely on message throughout the hearing, Turk stressed DOE’s commitment to getting the money out “urgently, but right.”

John Barrasso (Senate Energy and Natural Resources Committee) FI.jpgSen. John Barrasso (R-Wyo.) | Senate Energy and Natural Resources Committee

Sen. John Barrasso (R-Wyo.), ranking member on the committee, was doubtful from the outset, noting that between the IIJA and IRA, DOE had received a “staggering” amount of money — close to $100 billion — on top of its $40 billion annual appropriation.

“The question is not whether the department is going to waste taxpayer dollars, but how to reduce the amount that it will waste,” Barrasso said. He cited a letter from DOE Inspector General Teri Donaldson, noting that her office had received insufficient funds from the two laws relative to the amount of money to be monitored.

Barrasso raised questions about DOE’s announcement in November of a $200 million grant to Microvast, an American company that produces battery components and has 80% of its operations in China. In a January 2022 filing to the Securities and Exchange Commission, Microvast acknowledged that doing business in China does present substantial risks because of its government’s control of the business environment and foreign investment.

But the company is partnering with General Motors on a battery component factory to be located in the U.S., and the two companies are matching the DOE grant with a $300,000 investment.

Turk maintained that while the company had been “selected” for the grant, it has yet to receive any money. DOE is now in award negotiations with Microvast and GM, which will involve extensive due diligence, he said.

In a letter to Barrasso, Kathleen Hogan, DOE deputy undersecretary for infrastructure, stressed that such “thorough post-selection, risk-based due-diligence” was standard practice at the department. She also said that while Microvast’s technology was developed in China, the DOE grant would be used for a first-ever U.S. manufacturing facility, “obviating the typical risk of intellectual property.”

‘Asleep at the Switch’

The current tension between Manchin and the White House is rooted in their very different views of the fundamental goals of the IIJA and IRA. Biden hailed the IRA as an unprecedented investment in climate action. For Manchin, it’s about ensuring the energy security of the U.S. and the country’s ability to maintain its leadership as a global superpower to help its allies in the face of Russia’s invasion of Ukraine and its weaponization of energy.

“That’s why we said, let’s do a piece of legislation that uses the resources that we have … to be energy independent, using the fossil, horsepower we have, investing $369 billion to create the new technology — less carbon, if you will — but also not replacing what we need now until we have the other that can do the job. That’s all we tried to do. And I don’t know why we’re in denial,” he said Thursday.

Manchin sees such denial in the Internal Revenue Service’s late December release of guidelines for the IRA’s electric vehicle tax credits, in which the agency announced it was delaying guidelines on the law’s domestic content requirements until March.

As originally written, to qualify for the full $7,500 tax credit, an EV’s battery must contain a certain percentage of critical minerals sourced in North America or from a country with which the U.S. has a free trade agreement, and a certain percentage of other battery components must be sourced in North America. If one of the domestic content requirements is not met, a consumer may only get half the credit. While delaying the guidelines on domestic content, the IRS is allowing EV buyers to claim the full $7,500 credit.

Manchin has introduced a bill that would require the IRS to implement the domestic content requirements immediately and make them retroactive to Jan. 1, but he has been unsuccessful in bringing it to the Senate floor for a vote. (See IRA’s EV Tax Credits Spark Senate Debate.)

He also criticized recent guidelines from the White House Council on Environmental Quality directing federal agencies to factor in greenhouse gas emissions when evaluating projects, arguing that they will favor renewable projects over fossil fuels.

Both issues are not under DOE jurisdiction, though Turk said the department was consulting with the IRS on the EV rules.

Responding to Manchin and Barrasso, Turk acknowledged that the U.S. “has fallen asleep at the switch” on building out clean technology supply chains for batteries, as well as solar panels. “China really has a stranglehold now on mineral processing and all these intermediate steps, so we’re in a hole right now,” he said.

But he defended DOE’s grant-making process, which requires applicants to be U.S.-owned and operated, with U.S. headquarters. “The vast majority of our [IIJA] grants are competitive, and these are administered by civil servants. They’re done that way for a reason: to ensure integrity in the process; to ensure fairness in the process,” he said.

Input from industry experts and intelligence officials are also part of the review process, Turk said.

Turk also promoted DOE’s progress on IIJA implementation, reporting that of the $62 billion DOE received in the bill, $37 billion has been made available to communities across the country. Turk’s list of specific funding opportunities included $7 billion for regional hydrogen hubs, $750 million for electrolyzer manufacturing, more than $5 billion for “game-changing carbon management programs” and $3.9 billion for grid modernization.

The law’s $2.8 billion for battery materials processing and component manufacturing has been paralleled with more than $92 billion in public and private investment in battery manufacturing across the country, he said.

On the IIJA’s hydrogen hubs, Turk reported that DOE’s solicitation, released in September, drew close to 80 concept papers, 33 of which the agency identified as promising and asked for full applications, setting an April 7 deadline for submissions. Turk expects awards to be announced by the fourth quarter of the year, but he said that Energy Secretary Jennifer Granholm might “try to move that timeline up.”

Gas Stoves

While not directly related to either the IIJA and IRA, the political war over gas stoves was also on the agenda, with both Manchin and Barrasso railing against any attempt to ban the stoves in existing or new construction.

The Consumer Product Safety Commission triggered the controversy in January when Commissioner Richard Trumka raised the possibility of a ban because of the health hazards they present. The remark set off a firestorm of opposition and statements from both the CPSC and the White House that no such ban was being considered.

Manchin attacked both the CPSC and DOE, which on Wednesday issued proposed efficiency standards for cooktops, both electric and gas, framing the action as yet another attempt by the Biden administration to “find ways to push out natural gas.”

He said he and Sen. Ted Cruz (R-Texas) would be introducing a bill to prohibit the banning of gas stoves. “The federal government doesn’t have any business telling American families how to cook their dinner,” he said.

DOE’s proposed standards would limit the amount of electricity or gas a stove top can use per year. For electric stoves, those with open-coil cooking elements would be limited to 199 kWh/year and those with smooth element tops to 207 kWh/year. Gas stoves would be limited to 1,204 kBtu/year. DOE will be accepting comments on the proposal through April 3.

Echoing Manchin, Barrasso asked Turk to pledge that no money from the IIJA would be used “to ban or restrict the use of natural gas in new buildings.”

Thursday’s hearing also marked the debut of Sen. Josh Hawley (R-Mo.) as the newest Republican member of the committee. A controversial figure — he was the first senator to declare he would object to certifying Biden’s election in 2020 — Hawley spent his time browbeating Turk over the closure of an elementary school in his district, where radioactive waste was found in a nearby creek and later in the school itself.

Manchin intervened to explain that DOE has no jurisdiction to take action in the matter, and negotiations are ongoing with the U.S. Army Corps of Engineers, the agency that does.

NY DPS Decreases ZEC Prices by 14%

The cost of New York zero emissions credits is set to fall 14% for the next two years after the state agency that administratively sets ZEC prices issued its biennial price adjustment on Tuesday.

The New York Department of Public Service laid out the change in a letter to the state’s Public Service Commission. The letter explains that ZEC prices for Tranche 4 (April 1, 2023 – March 31, 2025), will be set at $18.27/MWh, down from $21.38/MWh for Tranche 3 (April 2021 to March 2023) (Case-15-E-0302).

Tranche 2 (April 2019 to March 2021) ZECs were priced at $19.59/MWh.

ZECs are subsidies for nuclear facilities that load serving entities purchase monthly from the New York State Energy Research and Development Authority to prevent those facilities from retiring. They play an integral role in the PSC’s Clean Energy Standard because they keep economically distressed nuclear plants, such as Nine Mile Point, James A. FitzPatrick and R. E. Ginna, online and use the collected funds to help build more renewable generation, which will replace the load generated by these nuclear plants.

Adjusted every two years, the ZEC is calculated by subtracting an adjustable reference price (currently $37.78) from the Zone A forecast energy price and rest-of-state forecast capacity price (currently $43.34/MWh). The difference between those is then subtracted from the social cost of carbon, which is currently set at $23.83/MWh.

The PSC has capped the number of ZECs that can be purchased, and that cap will be reduced should any facility close. Should any facility fall below the mandated production level of 85% of historical production for any two-year period, the PSC will further reduce the ZEC cap.

The program is intended to keep nuclear plants open until March 31, 2029, at which point New York expects to have installed enough additional renewable capacity to compensate for anticipated nuclear retirements.

ZEC prices will be adjusted again in 2025.

DOE: Physical Attacks, Sabotage Jumped in 2022

Incidents of deliberate physical damage to bulk power system facilities rose by 77% last year, driving home the danger posed by malicious actors, the Department of Energy reported this week.

DOE’s annual summary of electric emergency incidents and disturbances — based on reports submitted by utilities to the Office of Cybersecurity, Energy Security, and Emergency Response (CESER) — includes the type of event, demand loss in megawatts, number of customers affected, and region.

Out of the 390 incidents recorded in last year’s spreadsheet — up from 387 in 2021 — 163 involved deliberate physical damage to BPS equipment, a significant fraction of overall incidents and a major rise from the 92 recorded in 2021. The report also cites cybersecurity events (9), severe weather (95), fuel supply deficiency (5), generation inadequacy (4), system operations issues (87), and transmission interruption (27).

Among the incidents of physical damage, 90 were listed as involving “vandalism,” 57 as “suspicious activity,” 15 as “actual physical attack” and one as sabotage.

DOE did not provide details about how it defines these event types; the alert criteria listed in the report seem to be only loosely connected to the categories, with the same alert type provided for multiple types of events.

For example, “damage or destruction of [a] facility that results from actual or suspected intentional human action” is listed under both “suspicious activity” and “actual physical attack.” Additionally, there is some overlap between categories, with 10 incidents categorized as both “actual physical attack” and “vandalism.”

Most of the reported events resulted in no demand loss and affected no customers. The event with the biggest impact was December’s attacks on two Duke Energy (NYSE:DUK) substations in Moore County, North Carolina, when more than 45,000 customers lost power. The utility needed nearly a week to restore service to all those affected. (See Duke Completes Power Restoration After NC Substation Attack.) Investigators have yet to publicly identify any suspects or motives for the Moore County attacks.

The next-largest incident in terms of the number of people affected was the Christmas Day attacks in Washington state, when two men allegedly vandalized four electric substations in Pierce County, causing more than 21,000 customers to lose power. One of the men told police they committed the vandalism as part of a plan to burglarize a local business. (See Feds Charge Two in Wash. Substation Sabotage.)

By far the greatest number of physical security incidents — including the Washington attacks — occurred in WECC’s territory. The 73 WECC incidents affected more than 44,000 customers. SERC experienced 26 incidents, along with one event that it shared with ReliabilityFirst and three that affected it and the Texas Reliability Entity. These incidents, including those with RF and Texas RE, impacted more than 49,000 customers.

Events in the territory of the other REs affected a relative handful of people. Of the Midwest Reliability Organization’s six physical security incidents, one in Oklahoma affected 4,836 customers in July. The Northwest Power Coordination Council experienced 15 events, but only one — an event on Jan. 1 recorded as “suspicious activity” — affected 845 customers. RF reported several events in which the number of customers affected was unknown. Texas RE had no customers affected by its 17 incidents, although 1,521 were affected in a vandalism incident it shared with SERC.

FERC Resolves NextEra-Avangrid Dispute over Seabrook Circuit Breaker

FERC on Wednesday settled a dispute between NextEra Energy (NYSE:NEE) and Avangrid (NYSE:AGR) over whether the former should be responsible for upgrading a circuit breaker at the Seabrook nuclear plant in New Hampshire (EL21-3, EL21-6).

The two have been going back and forth on the project, which ISO-NE says is necessary to help support Avangrid’s New England Clean Energy Connect transmission line, since 2020.

NextEra, which owns and operates Seabrook, initially asked FERC to find that the plant should not have to take a financial loss in order to upgrade the breaker. Avangrid then filed a complaint arguing that Seabrook has been “unlawfully attempting to delay and unreasonably increase the costs of the breaker replacement.”

FERC essentially found that Avangrid’s reasoning for why Seabrook should replace the breaker was faulty, but that the nuclear plant can’t refuse to replace it because the breaker is a component of the generating facility and upgrading it is required by “Good Utility Practice.”

The nuclear plant’s interconnection agreement “does not permit Seabrook to refuse to replace the breaker when replacement is needed for reliable operation of the Seabrook Station and given the concerns in the record related to the impact of any unreliable Station operation on the reliable operation of the system,” FERC wrote.

And the principles of Good Utility Practice require Seabrook to replace the breaker before NECEC interconnects because the breaker will be “overdutied” once it does, the commission said.

An ISO-NE system impact study found that the breaker is operating at 99.6% of its capability now, but it would be at 101.2% once NECEC is in service.

While FERC has been considering the complaint, the two parties have been hashing out an agreement: The filing says that the breaker replacement is now scheduled for a fall 2024 refueling outage, with the commercial operation date for NECEC being December 2024.

According to FERC, both agree that Avangrid should pay for the direct costs of the breaker placement, but they disagree over whether the company should pay opportunity and legal costs.

FERC sided with Avangrid, saying that Seabrook can’t recover those additional costs.

“The commission typically allows opportunity cost recovery so that the resource will be revenue-neutral and therefore indifferent towards the system operator’s decision as to which service the resource will provide,” FERC wrote. “That is not the case here.”

Virginia Panel Clears Bills to Increase SCC Rate Authority

The Virginia House Commerce and Energy Committee voted to tighten regulation of electric utility rates as disparate interests lined up behind two bills.

Representatives of Gov. Glenn Youngkin (R), Attorney General Jason Miyares (R), Dominion Energy (NYSE:D), consumer groups, and environmentalists supported a pair of bills that the committee voted out unanimously. Democrats on the committee, environmentalists and clean energy advocates, however, opposed a third bill that they argued would stymie the goals of Virginia’s Clean Economy Act.

HB 1604, sponsored by Del. R. Lee Ware (R) would give the State Corporation Commission authority to reduce an investor-owned utility’s rates if it determines they would produce unreasonable revenue in excess of the utility’s authorized rate of return. Current law requires the SCC to set utility rates based on a group of investor-owned peers in the Southeast.

HB 1670, sponsored by Del. Daniel W. Marshall III (R), moves rate reviews for Dominion and Appalachian Power (NASDAQ:AEP) from every three years to every two years.

“This bill is part of three distinct pieces of energy legislation you’ll see today,” acting secretary of Natural and Historic Resources Travis Voyles said on behalf of the governor’s office. “These legislative efforts are central to the governor’s energy plan and the commonwealth’s ability to grow — grow population, grow jobs, grow businesses — by supporting a framework that makes certain the delivery of abundant, reliable, affordable, and increasingly clean energy.”

Democratic Del. Rip Sullivan also endorsed the two bills.

“This is one of those bills that a lot of people had a lot of opinions on; a lot of people got around literal and figurative and digital tables to talk it through,” said Sullivan. “The coalition of groups and entities that are supporting this bill, I don’t know if it’s unprecedented, but it is certainly, in my view, impressive.”

Rarely are Dominion Energy, Appalachian Voices, Virginia Poverty Law Center, Southern Environmental Law Center, Americans for Prosperity, and the governor’s office all supporting the same legislation, he added.

A third bill, HB 1770, requiring that the SCC approve the retirements of IOU electric generating plants, cleared the Republican-controlled committee on a 12-10 party-line vote. The requirement would not apply to any retirements identified in integrated resource plans filed with the SCC by July 1, 2023.

Sullivan and other members of the coalition backing the other two bills opposed the third, even though they all indicated it was better than it had been.

“The bill, in my view, is better than it was when it was first filed, better than it was two weeks ago, and better than it was yesterday,” said Sullivan.

While the legislation is on the right track and could be different by the end of the session when the House and Senate have to come together to pass any final legislation, Sullivan said he could not support HB 1770 as it stands now because it contains language that could be detrimental to the Clean Economy Act that he helped pass back in 2020, which sets Virginia on a path to decarbonization by mid-century.

The bill’s sponsor, Del. Terry Kilgore (R), said he was just trying to maintain reliability by requiring SCC approve generation retirements.

“This legislation brings important oversight to the SCC,” said Voyles, again speaking for Youngkin’s office. “This will directly improve the integrity of our grid and the reliability of power.”

Demand is growing in Virginia, and the legislation will ensure that no generation retires too quickly, preventing any gaps from occurring, he added.

Sullivan said that the Clean Economy Act already gives the SCC the authority to delay retirements as needed to maintain reliability.

The Clean Economy Act had clear language that laid out a plan to get to a clean energy future by mid-century, said Sierra Club Virginia Chapter Political and Legislative Director Connor Kish.

“Our concern with this language is it sort of cuts out the ability to have a set retirement date for these facilities that would help grow the industry as it continues to move towards a clean energy future,” he said.

Companion legislation for the three House bills voted out by the committee cleared the Senate Commerce and Labor Committee last week, but they have yet to receive a floor vote. (See Dominion-backed Bill Promises Savings, but Comes with Strings.)

Duke to Pay $75K in NERC Penalties

FERC has decided to let stand SERC Reliability’s $75,000 penalty against Duke Energy Florida (NYSE:DUK) for violating NERC reliability standards (NP23-7), along with the regional entity’s settlement with the Tennessee Valley Authority for another set of violations, carrying no financial penalty (NP23-8).

The commission announced last week that it would not review the settlements, which NERC submitted Dec. 29; the ERO submitted its monthly spreadsheet Notice of Penalty on that day as well, detailing SERC’s settlements with Virginia Electric and Power Co. for its facility ratings issues. (See related story, SERC Hits Virginia Electric with $320K in Penalties.)

Also approved last week were several settlements for infringements of NERC’s Critical Infrastructure Protection (CIP) standards (NP23-4, et al.). For these settlements, identifying information — including the utilities and REs involved, and when and where they occurred — was omitted, in accordance with NERC and FERC’s policy on CIP violations.

Duke Neglects to Coordinate Protection Settings

Duke’s penalty stems from a violation of PRC-001-1 (System protection coordination) that SERC discovered during a compliance audit in 2019. While the standard was not in place at the time of the audit, the RE determined that the violation began in 2012 when it was in effect.

Requirement R3 of the standard states that transmission operators (TOPs) must coordinate new protective systems and changes to protective systems with neighboring TOPs and balancing authorities, but SERC claimed that Duke failed to do so in 2012 and 2013 when it was conducting maintenance on its transmission lines.

The utility decided to change protective settings on its 115-kV line between Atwater and Quincy, increasing the timing on the zone 2 and 3 time distance relays to 45 cycles. However, it did not communicate the changes to the neighboring TOP, whose zone 3 relays remained set at 42 cycles. The mismatch remained in place until 2017, when the uncoordinated relays caused the neighboring utility’s breaker to trip, leading to a 63-MW loss of load on its system.

SERC found that this incident also constituted a violation of Requirement R5 of the same standard, which states that TOPs must inform neighboring TOPs of changes in their transmission systems that could require changes to the neighbor’s system. The RE said that Duke’s “failure to notify its neighboring TOP prevented the neighboring TOP from receiving sufficient information to review its systems and led to the transmission systems being mis-coordinated.”

Duke and its neighbor agreed to coordinate the timing cycles after this incident, and the changes were completed by May 2021. Additional mitigation actions by Duke include implementing setting changes to improve relay coordination and updating process documents to mandate coordination with neighboring transmission and generation owners.

TVA Reports Voltage, Maintenance Issues

The TVA settlements involve infringements of VAR-002-4.1 (Generator operation for maintaining network voltage schedules) and PRC-005-2 (Protection system maintenance). TVA self-reported both issues, which according to SERC comprised “multiple instances of smaller risk issues which, when aggravated, increase the overall risk of both to moderate.”

According to SERC’s filing, the utility initially reported its problems with VAR-002-4.1 on July 2, 2019, describing three incidents in which, as a generator operator, it failed to maintain the generator voltage schedule provided by its TOP as mandated by Requirement R2 of the standard. All three incidents occurred in April 2019 at TVA’s Watts Bar Nuclear Plant, located in Rhea County, Tenn. TVA later amended the self-report to include incidents at other nuclear and non-nuclear facilities it operated between 2018 and 2022, for a total of 287 excursions.

Mitigating actions undertaken by TVA include clarifying voltage schedule excursion requirements for responsible staff and updating equipment at affected facilities. The utility reported its completion of the mitigation plan on Feb. 2, 2022.

TVA’s violation of PRC-005-6 involved Requirement R3, which provides the schedule by which transmission owners, generation owners and distribution providers must maintain their protection systems and other components. The utility reported to SERC in May 2021 that it had discovered multiple instances of noncompliance; it had first detected the issues a year prior, but SERC determined that the violations extended as far back as 2015 and concerned PRC-005-2, the version of the standard that was in place at the time.

Places where problems were found include both transmission and generation facilities, some of which were also uncovered in the VAR-002-4.1 violation, such as the Cumberland Fossil Plant and Sequoyah Nuclear Plant. SERC and TVA identified various causes, including lack of internal controls and ineffective or inadequate internal controls. The utility’s mitigation steps included revising procedures within its PRC-005 program and creating training modules, along with testing and updates of equipment at affected facilities; the work is expected to be completed by August.

Because TVA is a federal government entity, SERC could not issue any monetary sanctions.

Washington Poised to Become Net Electricity Importer by 2050

OLYMPIA, Wash. — With its abundance of hydroelectric resources, Washington has long been a key exporter of power to other parts of the West.

But the state’s Department of Commerce now says Washington is poised to become a net importer of electricity by mid-century as it moves to decarbonize its economy — a development that has alarmed lawmakers.

In 2021, Washington sent more than 18% of its generation to its neighbors in the Western Interconnection. By 2050, the state will have to reverse that pattern and import more supply to reach its goal of weaning itself from fossil fuels, the agency has found.

One reason: a mandate that all new cars sold in Washington by 2035 must be electric vehicles. A lot of additional electricity will be needed to keep those cars running.

In fact, the state’s efforts to replace carbon-emitting fossil fuels translates into increased demand for electricity as a substitute, said Glenn Blackmon, manager of the Commerce Department’s Energy Policy Office.

“It’s replacing fossil fuels in every sector of our economy,” Blackmon said in an interview.

“Are we planning for the amount of electricity needed to recharge these [electric] automobiles?” Sen. Lisa Wellman (D) asked during a Jan. 13 hearing of the Senate’s Environment, Energy and Technology Committee.

According to data from the U.S. Energy Information Administration, in 2021 Washington generated almost 111 million MWh of electricity, imported slightly more than 5 million MWh, and consumed a bit more than 88 million MWh, translating into roughly 18 million MWh of net exports.

At the Jan. 13 hearing, Blackmon told the Senate committee that the state’s power needs will increase by 97% by 2050 — to almost 230 million MWh. That means Washington will have to import a huge amount of power by 2050, he said.

“That’s a big thing to say we will begin importing power instead of exporting it,” Sen. Shelly Short (R) said.

The Commerce Department predicts that by 2050 36% of Washington’s clean energy will likely come from wind farms in Montana and Wyoming.

“We need more capacity to site and permit clean energy projects in a timely manner, and we need to bolster our transmission infrastructure to reliably deliver clean energy throughout the state,” Jaime Smith, spokesman for Gov. Jay Inslee, wrote in an email to RTO Insider.

Greater Need for Connection

For almost a decade, Inslee has pushed aggressively to curtail fossil fuel use in Washington, finally achieving major policy victories in the last two legislative sessions. Those included the nation’s second cap-and-trade law and a low-carbon fuel standard that went into effect this year. The legislature also set a soft goal of 2030 for reducing sales of gas-powered vehicles, followed by Inslee’s mandate last year that no new internal combustion engine cars be sold in the state as of 2035.

Inslee’s goals build on a 2008 state law that sets carbon-reduction targets of 45% below 1990 levels by 2030, 70% by 2040 and 95% by 2050. A 2021 Commerce Department report put the state’s CO2 emissions at 99.57 million metric tons in 2018. The report shows that from 2016 to 2018, the transportation sector was the largest contributor, at nearly 45% of Washington’s emissions.

With the state planning to shift from gas-powered cars to EVs in the 2030s, Washington’s power needs will grow, along with a need for more transmission lines, Blackmon said.

An analysis published by the Seattle-based Sightline Institute last October put that issue into sharper focus.

“Cascadia, like the United States as a whole, suffers from a woefully underbuilt and aging electric grid,” wrote Emily Moore, Sightline’s director of climate and energy. “The grid is so inadequate that hundreds of proposed wind and solar projects are ending up at the back of waitlists where they may sit for years. … New transmission lines (the high-voltage lines that often stretch over mountain ranges and along rivers on tall, scaffolded towers) take a decade or more to construct, giving the problem increasing urgency with each passing year.”

Moore continued: “Unless Northwest policymakers develop a plan for building out the grid we need, and unless they start erecting it immediately — through the Bonneville Power Administration, state action, utility investment, or some combination of these means — the region’s ambitious decarbonization commitments will amount to so much hot air.… That’s right. We may fail the climate test because we’re missing some wires.”

While hard figures are not available, Commerce has determined that massive construction of new power lines between Washington and other states such as Montana, Wyoming and Oregon is needed by 2050.

The state’s utilities are legally required to identify and plan for future transmission needs.  However, Nicolas Garcia, representing the Washington Public Utility Districts Associations, last month told state senators that many utilities don’t have the expertise for transmission planning.

It takes 10 to 20 years to build a power transmission line corridor between Washington and another state, while it takes two to three years to build a solar or wind farm, Kathleen Drew, chair of state’s Energy Facility Site Evaluation Council, told the Senate energy committee at a Jan. 18 hearing on a transmission planning bill. Ten years is not long enough to tackle the studies, leasing, permitting, coordinating and construction of a transmission line corridor, she said.

Sen. Joe Nguyen (D), chair of the Environment, Energy and Technology Committee, has introduced Senate Bill 5165 to require utilities to begin using a 20-year planning horizon — instead of the current 10 years — to identify transmission needs.

State agencies, environmental groups and some utilities support the bill. But Avista Utilities and the Association of Washington Business said more details are needed on the processes and targets within the bill.

“It needs clearer standards and deadlines for agency decisions,” Avista’s John Rothlin said.

Can the US Deliver Competitive Batteries?

Three new battery technologies now under intense development in the U.S. may be key to expanding production of electric vehicles with longer ranges and faster charging times while challenging Chinese dominance of the global market.

Michigan-based Our Next Energy (ONE) and two California-based companies, Lyten and Natron Energy, explained their technologies and growth plans at BloombergNEF’s annual summit Tuesday.

Lyten, a Silicon Valley chemical manufacturer, is developing a lithium-sulfur battery it expects to market in 2025 or 2026.

Natron has developed and is already manufacturing UL-listed sodium-ion batteries that, while slightly less energy-dense than lithium-ion batteries, are nonflammable and not prone to overheating.

Deeana Ahmed, vice president of ONE, said the company has developed a battery capable of powering an EV for 600 miles per charge. The company’s battery is anode-free and built on chemistry designed to use less nickel and cobalt and more manganese, which is more abundant.

“We’ve been focused on the development of a North American supply chain since the founding of the company in July of 2020,” Ahmed said. “I think the momentum that we’ve seen has made that all the more plausible and possible, because we believe that by localizing our supply chain, we can then begin to approach those prices that you’re talking about with the scale up. …

“We’re partnering with BMW to demonstrate the 600 miles of range of … the platform this year. What we’re looking at is how do we grow the capacity or manufacturing capacity and maintain a conservative margin and then pass down the savings,” she said.

ONE expects “to bring manufacturing capacity online by 2024,” she said, adding that the company has already announced it will build a “gigafactory” in Michigan in the future.

The battery will “will have a very high cell to pack volumetric efficiency that allows that LFP [lithium iron phosphate] chemistry battery pack to be market-leading in terms of systems of level energy density, even when compared to a nickel cobalt battery product.”

Celina Mikolajczak, the chief battery officer at Lyten, said the company is developing lithium-sulfur battery technology even though combining the two elements “is a very difficult chemistry.”

Noting that lithium-ion batteries, especially advanced versions with higher nickel cathodes and lithium metal anodes, “are engineering wonders,” she said their high production costs mean they don’t provide “electrification for all.”

“And the reason is that there is a limited amount of nickel. And when you look at lithium sulfur, you say, ‘well, there’s a lot of sulfur out in the world. And it is very, very cheap. OK, if I can make that cell work, I make electrification something that’s abundant.’”

To tame the combination of the two elements, the company developed a graphene nanostructure carbon system that effectively controls the sulfur, she said. “The graphene helps us hold on to that sulfur, control it and make a practical battery.

“It gives us a lot of manufacturing opportunities and allows us to leverage a lot of the existing manufacturing technology. … It’s a wickedly hard chemistry, but the opportunity with it is rather incredible. It really means that we move away from petroleum as our transportation source that we allow electrification of literally everything.”

Colin Wessells, co-founder and CEO of Natron, said the company will begin mass manufacturing its sodium-ion battery in a new Michigan plant beginning this summer.

“We’ve really focused on the sodium-ion system, because it allows you to extract extraordinarily high power for energy stored,” Wessells said. “In some of our markets, some of our customers are data centers and microgrids; we have customers that are running at a 50-to-1 power-to-energy ratio.”

CAISO Approves Day-ahead Market for Western EIM

FOLSOM, Calif. — The CAISO Board of Governors and the Western Energy Imbalance Market Governing Body on Wednesday approved a plan to incorporate a day-ahead market into the Western EIM, calling it a milestone in regional grid integration.

“Today holds the promise for a new West, an opportunity for a new beginning in expanded markets and increased regional coordination,” WEIM Governing Body Chair Robert Kondziolka said in opening remarks. “The decision items at today’s meeting, if approved, are groundbreaking and profound.”

The extended day-ahead market (EDAM) proposal passed with unanimous votes from both governing bodies, which met in-person together for the first time since the pandemic began three years ago to exercise their joint authority over the WEIM.  

After years of planning and stakeholder meetings, the EDAM promises to greatly expand the amount of electricity traded in the sprawling WEIM, which will cover nearly 80% of load in the Western Interconnection once three new members join this year. The market now deals only with real-time transactions, yet it has generated $3.4 billion in benefits for its members since it went live in late 2014.

Real-time trades are only a small part of the electricity market. Day-ahead transactions represent a far larger share. Transactions in both timeframes limit curtailment of renewable resources, such as California’s abundant midday solar power, and allow for purchases of less expensive electricity during times of tight supply.  

A study prepared for CAISO by Energy Strategies found that the EDAM could generate $1.2 billion a year in benefits, or 60% of the savings of a West-wide RTO, if it encompassed the entire U.S. portion of the Western Interconnection.

The West, with its 39 balancing authorities in states divided by geographic and political differences, is pursuing several major regionalization efforts, any of which could eventually establish the first Western RTO. In addition to EDAM, the Western Power Pool is awaiting FERC approval to launch its Western Resource Adequacy Program, and SPP is planning its own day-ahead market and a Western version of its Eastern RTO.

CAISO must also win FERC approval for the EDAM, which it hopes to start operating in 2024 or 2025.

‘Important New Step’

PacifiCorp, a founding member of the WEIM, became the first entity to commit to join the EDAM in December. Others are expected to follow. The WEIM now has 19 members in all Western states, except for Colorado, and stretches from the Mexican border into British Columbia.

Key provisions of the EDAM design include a resource sufficiency evaluation intended to ensure participants can meet their internal demand for electricity before engaging in the day-ahead market — a means of preventing members from “leaning” on the market for supply. The final EDAM plan includes a tiered structure of financial penalties for failing to meet the test.

“The day-ahead RSE evaluates, across the next day 24-hour horizon, whether each balancing area’s supply offered into the day-ahead market is sufficient to meet its next day forecasted load, imbalance reserve obligation, and self-provisioned ancillary service obligations,” a CAISO staff memo to the boards said. “This includes functionality to allow each balancing authority to evaluate on an advisory basis its progress toward meeting the final RSE so they may take steps to cure any anticipated insufficiencies prior to the execution of the day-ahead market.”

It also includes a provision that market participants make their internal transmission available for EDAM transfers.

“The availability of transmission, both internal to the system and across interfaces between balancing areas in EDAM, is foundational to optimizing unit commitment in the day-ahead market and to identifying robust energy transfers across the EDAM footprint,” the memo says.

Balancing authorities in the EDAM will retain control of their resource and transmission planning.

A separate decision on EDAM governance approved a plan developed by the WEIM’s Governance Review Committee that adopts the WEIM’s joint authority model for the EDAM while broadening the scope of that authority as well as the WEIM Governing Body’s solo authority over certain matters.

The governance plan was developed during many hours of stakeholder meetings and was broadly supported.  

A third decision related to the WEIM and EDAM refined the ISO’s controversial wheel-through limits, which it enacted in 2021 as a temporary measure to promote in-state reliability during summer heat waves. A number of out-of-state WEIM members opposed the limits. (See FERC OKs CAISO Wheel-through Restrictions.)

Under its new plan, the ISO will calculate available transfer capability (ATC) to determine how much it needs and how much it can make available to others.

“In calculating the ATC, the ISO would set aside transmission capacity for forecasted or estimated native load needs, including load growth, and establish a transmission reliability margin (TRM) to account for different elements of uncertainty,” a staff memo said. “Management further proposes a process through which wheel through customers can request and access limited ATC that may be available on the intertie. The process requires them to demonstrate they have a firm power supply contract to serve external load or a contract conditioned on their ability to obtain ATC.”

Some stakeholders continued to take issue with the plan, saying it undermines open-access transmission principles,  the memo noted. CAISO staff said the “proposed design provides a reasonable bridge between the Open Access Transmission Tariff (OATT) framework and the current ISO market structure.”

Regarding EDAM, stakeholder comments were broadly supportive, though some came with caveats about details to be worked out later.

Stakeholder comments were broadly supportive, though some came with caveats about details to be worked out later.

A coalition of 26 entities from across the West — including major utilities, environmental groups and trade organizations — expressed written support for the plan while acknowledging there is more to do.

“The undersigned entities support Board and Governing Body approval of the EDAM Final Proposal,” the joint letter said. “To be sure, all the work is not yet done, and some entities will still need to conduct their own assessments of whether and when they might expect to join the EDAM, and seek regulatory approvals if applicable.

“There will be significant implementation and market mechanics to be worked through, and the potential EDAM entities will also have to reflect the new market in their own Open Access Transmission Tariffs under which they provide service to their transmission customers,” it said. “But the basics on governance, resource sufficiency, transmission access and revenue attribution, and greenhouse gas rules enable the start of an important new step in regional market evolution.”
