Federal Aid Likely Too Late to Save Palisades, Diablo Canyon Nukes

LANSING, Mich. — The U.S. Department of Energy’s lifeline to struggling nuclear generators appears unlikely to save the next three units scheduled to retire.

Entergy (NYSE:ETR) officials said Wednesday they are unlikely to seek federal aid to prevent the Palisades Nuclear Plant from closing as scheduled on May 31, despite entreaties from Michigan Gov. Gretchen Whitmer (D). And Pacific Gas and Electric (NYSE:PCG) said Diablo Canyon 1 and 2 are still scheduled for retirement in 2024 and 2025.

Whitmer sent a letter Wednesday to Energy Secretary Jennifer Granholm — her predecessor as governor — urging the department to use $363 million from the Civil Nuclear Credit (CNC) Program created by the Infrastructure Investment and Jobs Act (IIJA) to keep Palisades open. (See DOE Launches $6B Nuke Credit Program.) DOE opened applications for the $6 billion CNC program Tuesday.

Whitmer said saving the 800-MW nuclear plant, which employs 600 and is one of the state’s largest sources of carbon-free electricity, “is a top priority.”

Merchant Power Exit

But Entergy spokesman Nick Culp told RTO Insider the company would only reconsider its plans to close Palisades — part of the company’s broader exit from the merchant power business — if it received a purchase offer from a “credible formal buyer.”

In December, the Nuclear Regulatory Commission approved Entergy’s request to transfer Palisades, its nuclear trust fund and its spent fuel to Holtec Decommissioning International.

“Our focus at Palisades power plant remains on the safe and orderly shutdown of the facility in May,” the company said in a statement. “We acknowledge having recently been contacted by government officials about the facility potentially operating beyond May 2022. In addition to these conversations, we have and will continue to entertain discussions with qualified nuclear merchant plant owner/operators who may want to purchase and continue operating Palisades. However, it is important to note that no formal proposal to acquire Palisades has been made that provides an opportunity for continued operations and that eliminates the substantial financial and operational risks associated with unwinding the existing contract with Holtec.”

Entergy has been preparing to shutter Palisades since 2017 and has not refueled the plant since 2020.

“There are challenges that make continued operation of the facility beyond May 2022 difficult, including the pending transfer of more than 130 employees to other parts of Entergy’s business and planned employee retirements post-shutdown,” the company added. “Additionally, the plant is unable to operate beyond the target closure date due to the diminished power of its nuclear fuel as it reaches the end of its two-year operating cycle.”

Holtec issued a statement saying it was aware of Whitmer’s effort to keep Palisades operating. “We remain ready, should these efforts to keep the plant operational not be successful, to transition ownership to Holtec after the plant ceases operations for a safe, efficient decommissioning process,” it said.

Keeping Palisades open until at least the end of its current operating license, which expires in 2031, has split the state’s environmental community. While a number of environmentalists have called for keeping the plant open to aid decarbonization efforts, others oppose nuclear generation.

During public testimony on developing the MI Healthy Climate Plan — the final version of which is due to Whitmer by Friday, Earth Day — keeping Palisades open drew comments from supporters across the nation. The first version of the plan to make Michigan carbon neutral by 2050 did not discuss the plant.

Expiring PPA

CMS Energy’s (NYSE:CMS) Consumers Energy, which put Palisades into service in 1971, sold the plant to Entergy in 2015 while purchasing most of its output under a power purchase agreement scheduled to expire this year.

Entergy and Consumers agreed to end the PPA early and close Palisades in 2018, but they canceled those plans under pressure from the Michigan Public Service Commission. Prices under the PPA ranged from $43.50/MWh in 2007 to $61.50/MWh in 2022, with an average of $51/MWh.

A CMS spokesperson said the utility would not oppose continued operation of the plant, located in Covert Township on Lake Michigan. “If the power from the plant could provide competitively priced and reliable energy for our customers, we would consider working with our partners to keep the plant open,” CMS’ Katie Carey said.

Whitmer’s letter said that “Michigan has already had numerous conversations with the plant owner and leading nuclear operators who may be interested in purchasing the plant and keeping it operational through its 2031 [NRC] licensure date.”

“If another buyer does not materialize and Entergy maintains its stance, Gov. Whitmer might look to other sources of leverage to keep the plant in service, and Secretary Granholm could prove a valuable ally in this respect,” ClearView Energy Partners said Wednesday, citing two options: invoking the Defense Production Act to prevent plant closures, or seeking relief from the NRC.

The commission’s December 2021 press release announcing its license transfer approval said it was “subject to [the NRC’s] authority to rescind, modify or condition the transfer based on the outcome of any subsequent hearing on the application.”

In February 2021, Michigan Attorney General Dana Nessel requested a hearing on whether Holtec has sufficient financial strength to decommission Palisades. “If the NRC were to grant that request, it could delay the transfer (and perhaps even ‘rescind, modify or condition’ it),” ClearView said.

No Takers for First Round of CNC Program?

DOE says 12 commercial reactors have closed early since 2013 because of economic pressures. Illinois, New Jersey, Connecticut, Ohio and New York have approved subsidies to keep plants operating within their borders.

DOE’s CNC program will allow owners of commercial nuclear reactors at risk of closure to competitively bid on credits to keep them in operation. The IIJA requires applicants to prove their reactor will close for economic reasons and that the closure will result in increased air pollution. Credits would be allocated over a four-year period.

The department will accept applications for its first round of CNC funding through May 19. While the first cycle will be open to reactors that have already announced their intention to cease operations, future cycles — beginning with the second cycle in the first quarter in FY2023 — will “not be limited to nuclear reactors that have publicly announced their intentions to retire,” DOE said.

According to the Nuclear Energy Institute, Palisades and PG&E’s Diablo Canyon 1 and 2 are the only operating nuclear units that have announced retirement plans.

“PG&E is committed to California’s clean energy future, and as a regulated utility, we are required to follow the energy policies of the state,” PG&E spokesperson Suzanne Hosn told RTO Insider. “At this time, the state has not changed its position regarding the future of nuclear energy in California. The plan to retire Diablo Canyon Power Plant was introduced in 2016 and approved by the California Public Utilities Commission, the State Legislature and Gov. [Jerry] Brown in 2018.”

Matt Crozat, executive director of policy development at NEI, said his group “will work with our members to ensure this program [CNC] is as effective as possible and continue to advocate for a production tax credit, which will offer greater certainty for owners to make long-term investments in their carbon-free nuclear plants.”

New York Utilities Report Slow Start to EV Fast Charging

New York’s investor-owned utilities have seen a slow rollout of EV fast-charging stations under the state’s $701 million incentive program to build 50,000 such stations by 2025, according to reports filed with state regulators this month (18-E-0138).

Con Edison (NYSE: ED) reported 34 EV charging sites participating in its incentivized infrastructure program last year, including 25 Level 2 (L2) charging stations and nine direct current fast charging (DCFC) stations, collectively representing just 2% of the total 1,492 site applications received by the utility.

The company’s Orange and Rockland (O&R) subsidiary reported three charging sites operating, or nearly 10% of the 31 total site applications received.

The New York Public Service Commission’s DC fast charger order of 2019 established a per-plug incentive program to encourage development of DCFC stations and directed the state’s utilities to file detailed annual reports on the buildout. Similarly, the PSC’s make-ready order of 2020 established a program to encourage development of L2 and DC fast chargers throughout the state, providing incentives to offset the utility and customer capital costs of eligible charging infrastructure.

Customer Benefits

The commission last November issued its EV infrastructure order approving tariff changes to fund the make-ready program that incentivizes utilities and charging port developers to site EV charging infrastructure in places that best benefit drivers.

The PSC allocated a minimum of $206 million toward equitable access and benefits for low-income and disadvantaged communities, where EV charging ports are eligible for an incentive supporting up to 100% of site preparation costs.

The commission also directed the utilities to file detailed annual reports on these programs and to combine their make-ready program reports with their DC fast charger reports. The joint utilities hired Atlas Public Policy to serve as their common third-party contractor to help prepare the annual reports.

The New York Power Authority is dedicating $250 million through 2025 to its related EVolve NY program, which is installing fast chargers throughout the state, including a recently completed 10-charger site at JFK Airport.

In announcing a state-sponsored EV test track at the New York International Auto Show in April, NYPA Interim CEO Justin E. Driscoll said, “We will soon have 100 fast chargers strategically located throughout the state, including at airports, municipal and private parking lots and convenience store locations.”

Con Edison and O&R filed participants’ charging customer fee structures, charging revenue and operating cost data as collected by third-party data aggregator Atlas Public Policy, but confidentially, with relevant parts redacted.

Con Edison said 19 sites did not report their fee structure after at least four outreach attempts by Atlas and Con Edison to collect data, and four sites did not report valid operating costs after at least four outreach attempts.

Con Edison said it will continue to work with participants who are not currently reporting some or all data to bring them into compliance with the reporting requirements of the PSC’s order.

Central Hudson reported 5% of applications having matured into operational stations, with 16 L2 chargers and 21 DCFC stations working as of Dec. 31, 2021.

National Grid (NYSE: NGG) reported 431 applications received for its Niagara Mohawk Power subsidiary, of which 108 (25%) matured into operating stations, or paid projects, in 2021, including a total of four DCFC stations.

Avangrid (NYSE: AGR) subsidiaries New York State Electric and Gas (NYSEG) and Rochester Gas and Electric (RG&E) reported separately, with NYSEG reporting 21 charging stations operating out of 81 applications, including one DCFC station. RG&E reported no DCFC stations operating and 18 L2 stations operating out of a total of 78 applications.

Billing Details

As directed by the commission, all IOUs exempt from the EV surcharge the portion of load served under the Excelsior Jobs Program, which provides a state tax credit of 6.85% of wages per new job created.

Central Hudson includes cost recovery for the EV infrastructure surcharge from non-demand customers under the category of “miscellaneous charges,” with the combined amount shown as one line item on both regular and demand-billed customers’ bills.

According to NYSERDA, the demand charge is a monthly fee that customers pay as part of the cost of maintaining the electric utility’s infrastructure required to deliver electricity to the building or site. For large commercial or industrial customers, demand charges make up a sizable portion of their utility bill, with the amount based on peak energy use measured in kilowatts.

Con Edison is including its EV surcharge in the “monthly adjustment clause” line item on customers’ bills and collecting the surcharge $1/month basis for NYPA customers. O&R includes the surcharge in its “energy cost adjustment” line item.

National Grid includes the EV surcharge in the delivery rate line item on customer bills, while NYSEG and RG&E add it to their respective “transition charge surcharge” line items on customer bills.

Midwest Energy Policy Series Addresses JTIQ Projects

MISO and SPP planners discussed the prospects of the Joint Targeted Interconnection Queue (JTIQ) projects during a Tuesday infrastructure session of the Missouri Energy Initiative’s Midwest Energy Policy Series.

The seven projects in the $1.65-billion JTIQ portfolio are projected to resolve 48 reliability constraints and enable 11.1 GW of generation projects on SPP’s side of the RTOs’ seam and 17.5 GW of projects on the MISO side. The grid operators are hoping to receive the portfolio’s approval by the second half of 2023, but they first must hammer out a cost-allocation methodology for the projects. (See Now, the Hard Part: MISO, SPP Tackle JTIQ Cost Allocation.)

“Unfortunately, we’re not quite over the hump just yet. … We still have to figure the cost allocation to get these projects built,” MISO Director of Resource Utilization Andy Witmeier told attendees.

But both he and SPP’s Neil Robertson, senior engineer of interregional relations, agreed that the study has been a success so far.

Robertson said planners were given a “free hand” in developing the study, “unique” among their interregional planning, which is usually scripted according to their joint operating agreement.

Witmeier agreed that planners were given a “blank page” to study the transmission needs of multiple generator interconnection cycles in the RTOs’ queues.

Robertson said staff are trying to distribute costs based on the projects’ beneficiaries, including MISO load, SPP load, and interconnection customers on either side of the seam whose generation will flow between the footprints.

“We continue the theme of the free hand in developing innovative solutions here,” Robertson said of a cost-sharing design.

Witmeier said the grid operators’ “guiding principle” of cost allocation will underscore the study’s aim to maximize capacity additions. He said while the two might consider assigning costs based on added benefits like increased flows or more economic dispatch, they will be secondary and fleshed out later.

Witmeier also said project duplicates between the JTIQ and MISO’s regional long-range transmission plan (LRTP) emphasize the projects’ necessity. MISO has decided that it will independently pursue 345-kV LRTP projects in North Dakota and Minnesota before they are included in the JTIQ study. With the two projects, the JTIQ portfolio would be reduced to about $1 billion. (See MISO Stakeholders Uneasy Over Long-range Tx, JTIQ Overlap.)

“It certainly means that it’s transmission that needs to be built now,” Witmeier said of the LRTP projects. He said MISO has decided it needs the lines now, rather than later, to reliably serve load, support new generation, and keep pace with members’ changing resource portfolios.

“We see benefits to these projects now,” he said, noting that MISO already has worked out a cost-allocation design for the LRTP.

The planners acknowledged that the RTOs’ results differ in how much new generation the JTIQ portfolio can facilitate. They said they used their respective planning models and generation dispatch assumptions to estimate gigawatt amounts.

“This was not what in the planning world we would call a common model study,” Robertson said. “We did not collectively develop a single model that both organizations performed analyses on. We levered our regional model processes.”

Had the RTOs tried to develop a common model, Witmeier said, “we’d still be doing the analysis today.” He said creating a common model would be too time-consuming to meet their 18-month study timetable.

The planners also said the JTIQ study forced them to pivot from a “first-come, first-served” queue priority approach to a “first-ready, first-served” method.

Witmeier said MISO is still processing applications that were submitted in 2019 and 2020, while SPP is working on interconnection requests submitted in 2017. In some cases, MISO interconnection customers that entered the queue in 2018 are already signing generator interconnection agreements, the final step before grid access.

“It doesn’t make sense for our projects to be held up by the projects in SPP’s queue that still haven’t been sited yet,” Witmeier said. Robertson agreed that the grid operators must “evolve” beyond the instinct that whoever lines up first must finish first.

Panel moderator and RTO Insider Editor-in-Chief Rich Heidorn asked whether MISO and SPP are worried about state commissions opposing JTIQ transmission projects.

“I feel like MISO and SPP have both been very successful in recent years in getting a significant amount of transmission expansion projects built,” Roberston said. “I can’t necessarily say it hasn’t been without its bumps in the road, but we have shown a consistent track record of success over the last, let’s say, decade or so.”

Robertson acknowledged that MISO’s and SPP’s footprints contain multiple states with right-of-first-refusal laws and the RTOs “will have to account for that.”

“We have a number of conversations ahead of us in getting to a complete cost-allocation methodology and accounting for the nuances around actually getting these facilities sited and constructed is certainly going to be a prominent component,” he said.

Heidorn also asked whether MISO was considering speeding up plans for a project that could increase MISO’s transfer capability between its Midwest and South region. He noted MISO Midwest came up short on supply in last week’s capacity auction. (See MISO’s 2022/23 Capacity Auction Lays Bare Shortfalls in Midwest.)

Witmeier said MISO is discussing the potential of accelerating the study of potential projects. The RTO is not planning to address Midwest-South transfer projects until the final cycle of its four-part LRTP. (See MISO Seeking New Tx Cost Allocation for Major Buildout.)

MISO may “pull that trigger and move that forward,” Witmeier said.

However, he said, any approved transmission project is years away from allowing increased flows between the regions.

“That’s not going to be an immediate fix,” he said.

Experts Expect Carbon Capture, Storage, Renewables

Other series panelists predicted a raft of renewable generation, carbon capture and energy storage ubiquity in the Midwest, but they worried that lengthy interconnection queues will hold up necessary capacity.

Evergy’s Kayla Messamore said renewable technologies can’t singlehandedly meet all capacity needs. She predicted carbon capture, some nuclear generation and hydrogen generation will make up “that last 20%” of fuel resources that need to be “a little more firm.”

When asked what she would spend $1 billion on over the next five to 10 years to accelerate the energy transition, Messamore said she’d invest in a combination of wind and solar, longer-duration storage, and demand side management.

Anna Sommer of the Energy Futures Group said spiking energy prices should have more utilities focusing on demand response to control rates.

Messamore also noted that prohibitively high IC costs are limiting the generation that could interconnect to the system. She said new transmission is needed to integrate renewable generation and prevent energy price separation between regions that can’t access low-cost renewable energy.

Great Plains Institute’s (GPI) Patrice Lahlum said carbon capture and sequestration is poised for major growth.

She said that currently, 12 commercial-scale U.S. facilities capture about 25 million metric tons of CO2 annually. She said the nation’s growing carbon-management industry could deliver a 13-fold increase in CCS capacity by 2035, resulting in 210-250 million metric tons of annual emissions reductions.

Lahlum said GPI has tracked nearly 90 announced projects since 2018, with more than 50 announcements in 2021 alone.

She noted that the Infrastructure Investment and Jobs Act contains more than $12 billion in funding for carbon management. She said it’s up to the industry to work together and create successful projects that capture emissions as intended.

Consortium for Battery Innovation’s Matthew Raiford predicted a flourishing market for lead acid batteries. He said the advanced batteries are easily recyclable, keeping materials in a stable supply chain.

Some panelists worried about the hostility that existing renewable technology faces in the Midwest.

Renew Missouri’s James Owen said some Midwestern communities are still anxious about wind development and mount opposition campaigns over noise levels, turbine height and blinking lights.

“We still think there’s a lot of people that have a lot of misinformation,” he said.

Owen said social media is a hotbed for false narratives that influence the public and lead to restrictive ordinances.

Enel North America’s Gina Mace said combatting misinformation in communities is a major task for her company. She also agreed backlogged and time-consuming queues remain an obstacle to getting new generation built.

Mace also said though it appears transmission can support new generation, transmission construction can take the better part of a decade. She said it’s unclear how near-term generation will come online.

Owens added that he remains concerned that a state public service commission can effectively veto multistate transmission projects.

BlackRock Decision Unearths FERC Wariness of Investor Influence on Utilities

FERC on Wednesday agreed to reup BlackRock’s (NYSE:BLK) blanket authorization to buy stock in utility companies for another three years, but not without some of the commissioners saying they were wary of the power of massive investors to shape energy companies’ decisions (EC16-77-002).

The four participating commissioners (Commissioner James Danly having recused himself) saw no reason to upend a precedent set more than a decade ago by FERC, which allows the company to own up to 20% of any individual utility.

The investment giant had first requested a blanket authorization in 2010. FERC approved it at that time and has extended it twice since.

“We find that the reauthorization will not have an adverse effect on competition, rates or regulation,” the commission said. “As applicants explain, there have been no changes in material facts and circumstances since issuance of the blanket authorization order that would alter or affect the commission’s prior analysis.”

The reauthorization was not without opposition: Consumer advocacy group Public Citizen filed a protest arguing that it is “impossible for a fund manager of BlackRock’s size and scope to remain a passive investor.”

“BlackRock’s accumulation of voting securities constitutes control over utilities, and its horizontal power over competing utilities harms competition,” the group wrote, calling for a hearing to assess the company’s influence.

FERC denied that request, writing that BlackRock has given it enough assurance that it will not be able to influence utilities. But commissioners from both parties said that they had taken heed of Public Citizen’s warning and are eager to closely examine the way FERC examines such requests in the future.

“I acknowledge Public Citizen’s concerns about the lack of analysis on the effects on competition, just and reasonable rates, and regulation related to the accumulation of acquired interests in public utilities,” wrote Democratic Commissioner Allison Clements.

She said that FERC should take a look at the analysis it requires when evaluating blanket authorizations to make sure any transactions they lead to “do not have an adverse effect on competition and that entities granted such blanket authorizations lack control over the utilities whose interest they acquire.”

Republican Commissioner Mark Christie also said that the worries raised by Public Citizen were “compelling” and called for future scrutiny into investment companies’
control over utilities.

BlackRock in particular, Christie wrote, has been “openly aggressive” in trying to influence corporate policy using its financial power.

“The important question is whether huge asset managers like BlackRock are able to exert undue pressure on regulated public utilities or their holding companies to engage in practices that may undermine their primary responsibilities of delivering reliable power to consumers at just and reasonable rates,” Christie wrote.

Siting Official Raises Habitat Concern over Wash. Solar Growth

A Washington energy siting council member is requesting a look at the cumulative effect of solar farms on the state’s Yakima River Valley after the agency recently received applications for two new projects in the area.

Yakima County in Central Washington is split west-to-east by the valley, with a U.S. Army training ground covering its north side and the Hanford Nuclear Reservation bumping against the northern half of the county’s east border.

The area is predominantly shrub-steppe, a treeless, sagebrush-filled semi-desert that is home to unique vegetation and animals, including greater sage grouse, which are listed as endangered by the state. Yakima and the surrounding counties are host to many solar proposals.

Shrub-steppe still covers a good chunk of Eastern Washington, but farms and towns have been gobbling up land for more than a century. The shrub-steppe has shrunk from an estimated 10.4 million acres filled with unique birds and critters in the 19th century to 40% of that today.

North Carolina-based Cypress Creek Renewables submitted applications to state’s Energy Facilities Site Evaluation Council (EFSEC) on April 7 to develop two 80 MW solar farms — High Top and Ostrea — near the county’s eastern border, just south of the Army training center.

At least two other solar farms are under consideration. EFSEC is considering whether it will approve the 80 MW Goose Prairie Solar project in the western part of the valley, while the Yakima County government is considering approval of the Black Rock solar farm near Goose Prairie.

Washington has a patchwork approach to approving wind and solar projects, giving renewable energy developers the choice of seeking permits from either the state or host county governments. If a developer chooses the state option, the EFSEC reviews the application and makes recommendations to the governor for a final decision.

During a Tuesday briefing on the High Top and Ostrea projects, EFSEC member Mike Livingston noted that the two projects are on a chunk of land that connects the Army’s Yakima training center and the Hanford reservation, both of which protect shrub-steppe lands within their borders. Livingstone said the four projects are strung along the training center’s southern boundary.

Livingston said solar farms might block unique species such as sage grouse from traveling from one area to the next.   “We need a cumulative impact study [on the environmental effects],” he said. “We’re going to lose the connectivity we have in this area.”

Livingston is not the first Washington official to raise a red flag on the potential impact of solar on the state’s shrub-steppe areas. Last September, Department of Fish and Wildlife staff and members of the state’s Habitat Committee expressed concern that solar developers were neglecting to investigate sensitive species and habitat impacts before locking into project development sites. (See Eastern Wash. Solar Projects Endanger Sensitive Habitat.)

Cypress Creek expects construction of the two solar farms to take nine to 18 months. The company has requested an expedited approval process from EFSEC, meaning a public hearing must be conducted by June 6.

Cypress Creek has built roughly 8 GW of solar projects and owns and operates about 1.6 GW of solar across the country, the company’s director of development, Tai Wallace, told the EFSEC.  “We’ve developed quite a few projects of this scale.”

Solar Sector Braces for Tariff Probe Impact

A U.S. Commerce Department investigation into claims that China circumvented U.S. tariffs on solar components is already having a chilling effect, with developers and industry groups saying they are seeing component price hikes, delivery delays and shortages as manufacturers in the countries under investigation pull back on exports to the U.S.

In an investigation launched March 25, the department is looking into whether crystalline silicon photovoltaic cells imported from Cambodia, Malaysia, Thailand and Vietnam are really made there, or if they are actually made in China and shipped through those four countries to avoid anti-dumping and countervailing duties that would otherwise have to be paid by Chinese manufacturers.

Anti-dumping duties are levied when the department concludes that a foreign supplier or manufacturer is selling goods on the U.S. market at below-market prices. The department places countervailing duties on a product when it assesses that a foreign government subsidized the supplier or manufacturer to reduce the price in the U.S. market. Crystalline silicon photovoltaic cells are used in the manufacturing of solar panels.

Even though the Commerce Department has only just started the investigation and made no conclusion, manufacturers and suppliers in the four countries are limiting exports to the U.S. out of fear that further tariff increases will be levied retroactively if the department eventually rules that circumvention took place, industry groups and developers say. The Solar Energy Industries Association (SEIA) has said that more than 80% of solar modular imports come from the four countries, and the probe as a result will affect a wide swath of the solar sector.

“These actions are so detrimental to what we’re trying to do,” Mike Kruger, CEO of Colorado Solar and Storage Association, said about the department’s decision to launch the probe. “My folks doing large-scale projects are already looking at renegotiating [power purchase agreements], potentially pushing out due dates for their projects” by as much as six months, he said. Some developers just won’t bid on jobs, because they don’t know either how much the panels will cost or when they will be available.

Kruger added that solar developers are faced with trying to work out whether to price jobs at the existing solar panel price or at the price elevated by higher tariffs that will take effect if the Commerce Department concludes that circumvention is taking place.

“It’s created a lot of challenges here in the short term,” said Jefferson Gerwig, director of procurement for South Bend, Ind.-based Inovateus Solar, which develops solar and energy storage projects for commercial, industrial, municipal and utility customers.

Some manufacturers have raised prices by a “significant” amount, and some have changed the delivery terms on their products, no longer offering to bring them to the buyer’s door and instead requiring that the customer pick them up at the factory. That way the buyer would be responsible for any tariff increase levied in the future, he said.

“This is going to have an impact on our pricing,” he said. “And it’s going to require us to go back and rebid many of our active proposals. So, it is having immediate impacts. We are having to shift numbers and let our customers know that the validity of their quotes needs to be updated, based on these initial price increases that we’re seeing.”

Tim Powers, development and policy manager for Inovateus, said the uncertainty of getting products has created a “mad rush to get modules as quick as possible. And that just puts a supply-and-demand constraint on the entire industry, and that causes challenges for everybody.”

‘Existential Crisis’

The investigation, and the reaction of the solar industry, highlights the tension between efforts to create a domestic solar panel manufacturing industry in the U.S. and developers seeking the lowest priced equipment for their projects as the nation seeks to accelerate its solar generation capacity power to meet its zero-emission goals.

The turbulence in the panel supply sector comes as the industry already is facing equipment shortfalls, delays and price hikes because of supply chain problems, mainly caused by the country’s emergence from the COVID-19 pandemic.

With the probe underway, the Commerce Department said it will identify the key exporters or producers in each of the four countries and request “quantity and value” data about their shipments of photovoltaic cells and modules. The department will make a preliminary determination in the case in August, and SEIA said it expects the department to make a final determination in January. It could lead to even higher tariffs on solar panels, the organization said.

SEIA said on April 7 that it had surveyed 412 solar companies nationwide, of which 78% said that panel deliveries had been canceled or delayed since the Commerce Department announced the investigation. Fifty-six percent said the investigation put at least 70% of the projects in their pipelines at risk this year.

SEIA CEO Abigail Ross Hopper called the department’s investigation an “existential crisis” for the solar industry and criticized the fact that the case is based on the “industry killing claims” of only one company.

“The proponents of this case say that harsh tariffs are necessary to grow domestic manufacturing; that this case will have no adverse impact,” she said in a SEIA webinar earlier this month. “And if it does cause harm, that’s OK: The ends justify the means. They’re wrong.”

But the Coalition for a Prosperous America (CPA), a trade group that advocates for domestic producers, welcomed the investigation.

“Despite the fear mongering and lobbying by special interest groups that advocate for Chinese solar manufacturers, the Biden administration has chosen to side with American companies and workers,” CPA Chairman Zach Mottl said.

Coping With Shortages

In New Jersey, concern at disruption to the flow of solar panels is “freezing … slowing” development and causing “significant price impacts,” said Fred DeSanti, executive director of the New Jersey Solar Energy Coalition, which represents 26 state and national solar companies. Price hikes put developers in a bind because they can’t adjust their two main sources of revenue — state incentives and the price of energy — to offset the rise in project costs, he said.

In a Feb. 24 letter to Commerce Secretary Gina Raimondo, DeSanti urged the department not to start the investigation, saying that the inquiry could “could threaten existing and future solar projects that rely on imports, in addition to the well paid solar jobs that these projects create.”

New Jersey, like other states, is looking to rapidly expand its solar capacity to help reduce carbon emissions. Gov. Phil Murphy has set a goal of reaching 100% clean energy by 2050, with a goal of increasing solar capacity from about 3.84 GW at present to 17.2 GW by 2035. The state’s strategy for expanding the solar sector includes introducing a community solar program, increasing the number and capacity of grid-scale solar projects, and refocusing the state’s solar incentive programs while also reducing the cost to ratepayers. (See NJ Solar Pipeline Surges While Installations Drop.)

That kind of dramatic expansion, however, would suffer if, as the developers say, they couldn’t get the equipment needed to follow through with projects.

Scott Elias, director of Mid-Atlantic state affairs for SEIA, told the New Jersey Board of Public Utilities (BPU) on April 7 that the investigation “is already needlessly causing serious harm to the industry, including right now and right here in New Jersey.” He said that “no importer of record is going to bring solar cells or panels into the U.S. and risk the imposition of a retroactive 50 to 250% duty.”

“Solar customers do not have the capacity to absorb these massive costs,” he said. “And planned projects are unfortunately not going to be moving forward.”

In Colorado, Kruger said that in the longer term, developers that are forced to slow down business because of higher panel prices or delivery delays, as well as lay off workers, could find it difficult to take on new people in the future because of the tight labor market.

“So, this is just really frustrating,” Kruger said. “The uncertainty; the unknown: It’s immediately impacting the large-scale projects but will impact everybody in the not-too-distant future.” That will put in jeopardy the state’s efforts to cut emissions with solar energy, he said, predicting that instead of the state seeing the hoped-for double-digit growth in solar capacity over the previous 12 months, it will simply repeat the modest increase of 2021.

Yet the blowback from the investigation is not hurting all sectors of the industry.

Renova Energy, a Palm Desert, Calif., solar installation company, said that it has yet to be affected by the investigation and does not expect to see much impact in the future. One reason is that the company buys all its equipment from SunPower, which has a wide diversity of panel manufacturing sources that are outside the four Asian countries under scrutiny — among them Mexico — and, therefore, is unaffected by the Commerce Department’s action, Chief Sales Officer Nate Lewis said.

Renova officials also said the company’s focus on rooftop solar installations with higher quality panels, which have a higher energy conversion rate and longer life, means that it does not use the lower-end panels that are made by the manufacturers in the Commerce Department probe.

“We typically don’t look for the lowest cost equipment; we’re looking for the best value for our customers,” Lewis said. “And the cheap Chinese product doesn’t work well in our environment.”

A Fair Playing Field

The dispute over Chinese solar panel imports stretches back a decade, since the U.S. International Trade Commission concluded that Chinese producers of crystalline silicon photovoltaic cells had dumped and subsidized imports into the U.S., which placed anti-dumping and countervailing trade duties on those products.

Six months ago, the Commerce Department rejected a request by trade group American Solar Manufacturers Against Chinese Circumvention (A-SMACC) seeking an investigation into unlawful circumventing of antidumping and countervailing duties in the solar module market. Announcing the request in an Aug. 16 release, A-SMACC said it wanted to “ensure that the playing field for American solar manufacturing is level and ready for the scaled investments necessary to address climate change.”

“This targeted enforcement action ensures that the United States’ status as an innovation and manufacturing leader will not be endangered by exploitative trade practices that harm the American worker,” A-SMACC said.

But the Commerce Department rejected the request, saying that it could not conduct an investigation unless A-SMACC identified its members, which the department would need to know to ensure that the complainants were legitimately “interested parties.” The organization declined, claiming that that such information was “proprietary.”

The Commerce Department, however, launched the current investigation after Auxin Solar, a California-based manufacturer of solar panels, made similar claims.

The department is required to investigate several factors about the products, according to a memo explaining the decision to investigate. One is whether the solar panels are produced in the four countries using merchandise produced in China.

Other factors include how significant the work done in the four countries and whether the merchandise produced is “a significant portion” of the final value of the product that is shipped to the U.S., the memo says.

Shortfall of R&D, Investment

Auxin says that Chinese manufacturers and suppliers responded to the anti-dumping and countervailing duties by changing their tactics. Instead of “fairly pricing” their products, the producers shipped imports from “third-country export platforms,” the company told the department in its complaint.

“Their relentless predatory pricing has been fueled by China’s non-market subsidization of the upstream solar supply chain, intellectual property theft conducted by China’s People’s Liberation Army [the country’s military] and inhumane forced labor practices,” Auxin said.

Auxin provided evidence that producers in Cambodia, Malaysia, Thailand and Vietnam obtained products used in the production of solar panels — such as silicon wafers, silver paste, silane, solar glass, aluminum frames and junction boxes — from China, the department said in the memo. The company also showed that the four countries had experienced “recent surges” in the import of those products, it said.

In addition, China has as much as “99% of the worldwide solar wafer capacity, 95% of the worldwide solar ingot capacity and 64% of solar-grade polysilicon capacity,” the memo says. “According to Auxin, this demonstrates that the solar cell producers in Cambodia, Malaysia, Thailand and Vietnam would likely obtain solar-grade silicon wafers from China.”

Auxin also argued that the four countries had not made the kind of investment in polysilicon enrichment facilities to support the volume of production it was claiming, especially compared to the extensive Chinese investment in the same thing, according to the memo. And the countries also had made “minimal” investment in R&D related to completing and assembling solar cells into modules and so relied on Chinese knowledge rather than “developing their own technology,” the memo said. In addition, the comparatively small size of production facilities compared to Chinese facilities showed that the production facilities in the four countries are “limited,” the memo said.

Massachusetts Senate Passes Bill to Amend OSW Price Cap Rules

The Massachusetts Senate on Thursday passed a bill 37-3 that would adjust the state’s existing offshore wind procurement price cap if enacted.

As passed, the bill amends Gov. Charlie Baker’s proposal (H.4204) to remove the existing OSW price cap, allowing instead a 10% increase over the winning per-megawatt-hour bid of the state’s previous procurement round. Under the current process, regulators cannot approve a bid that exceeds the winning bid of a previous procurement.

The total bid increase, however, must come from performance-based economic development and employment opportunities that support low- and middle-income populations and diversity, equity and inclusion programs.

Baker’s proposal became part of An Act Driving Climate Policy Forward (S.2819) (Drive Act) through a series of amendments (H.54524) in the House of Representatives that compile a broad set of policies for decarbonizing energy, transportation and buildings. The bill preserves Baker’s proposal to transfer the authority for selecting winning bids from the state’s utilities to the Department of Energy Resources (DOER).

The Drive Act is now before the House for final reconciliation and will go to the governor for his signature.

An amendment to the Drive Act introduced by Sen. Julian Cyr (D) and adopted during Thursday’s session would create a new phase in the state’s 83C OSW procurement process by tacking on 4.4 GW to an existing 5.6 GW procurement authorization.

The new authorization “would have Massachusetts realize one-third of President Biden’s goal to have 30 GW of offshore wind by 2030,” Cyr said on the Senate floor. “It establishes the trajectory for Massachusetts to realize the 15-20 GW of OSW needed under the pathways forecast in the Massachusetts 2050 Decarbonization Roadmap.”

Cyr’s amendment includes protections for coastal and marine environments and wildlife as well as provisions to ensure that federally recognized tribes have a voice in the OSW development process.

Funding

The Drive Act reduces Baker’s proposed $750 million Clean Energy Investment Fund in H.4204 to $100 million. Directives for the center’s funding include clean energy research and workforce and port infrastructure development.

An additional $100 million would be allocated to an Electric Vehicle Adoption Incentive Trust Fund and $50 million to a Charging Infrastructure Deployment Fund. Incentives under the EV fund support passenger car or light-duty truck purchases under $50,000.

A new interagency coordinating council would oversee the infrastructure deployment fund and deliver a report on deployment strategies to the legislature within a year of the bill’s effective date.

Transportation

A plan by the Massachusetts Bay Transportation Authority to electrify its bus fleet by 2040 would become law under the Drive Act, and all the authority’s passenger bus purchases or leases would have to be zero-emission vehicles starting in 2028.

An amendment introduced by Sen. Brendan Creighton (D) and adopted by the Senate would direct MBTA to purchase only electric rail cars by 2031. In addition, the authority would have to develop emission-reduction plans for each of its commuter rail lines.

Senators defeated another amendment that would have required electrification of public fleets, including state fleets and school buses, by 2035.

“Adoption of the provision requiring a phased plan for the electrification of commuter rail that prioritizes environmental justice communities is a welcome decision,” Veena Dharmaraj, director of transportation for Sierra Club Massachusetts, said in a statement.

Sierra Club, she added, is “disappointed” that legislators are reluctant to set fleet electrification targets.

“Communities across the state should not have to wait until 2050 to benefit from pollution-free school buses and municipal and transit fleets,” she said.

Buildings

In keeping with Massachusetts’ efforts to establish a net-zero stretch code that local governments can adopt, the Drive Act would allow a demonstration project for up to 10 municipalities to restrict fossil fuel use in new building construction. DOER would collect data from the project to help assess the effect of fossil-fuel free development on building emissions and costs.

An amendment introduced by Sen. Rebecca Rausch (D) and passed by the senate would direct utilities to provide public annual reports on the amount of natural gas and electricity used in buildings of more than 25,000 square feet.

Environment Massachusetts supported the amendment.

The bill “doesn’t do nearly enough to address the energy we use in our buildings,” Ben Hellerstein, state director for the nonprofit, said in a statement.

Senators defeated a separate amendment that would have established a large buildings energy performance standard like one passed last year for Boston.

The bill also addresses the decision-making process for the Department of Public Utilities’ ongoing investigation (Docket 20-80) into the role of gas distribution companies in reducing greenhouse gas emissions. Regulators would be required to hold an adjudicatory proceeding before approving any state gas utility’s decarbonization plan submitted under the investigation.

Adjudicatory processes would allow constituents to participate as intervenors in hearings and depositions.

Massachusetts’ gas utilities filed proposals with the DPU in March for reducing gas system emissions. Stakeholders have asked the DPU to expand the opportunity for input on the utilities’ proposals in the docket, including provision of technical evidence and cross-examination of utility witnesses.

PJM MIC Briefs: April 13, 2022

Start-up Cost Offer Development Endorsed

PJM Market Implementation Committee members last week unanimously endorsed a revised proposal from the RTO and its Independent Market Monitor to address start-up cost offer development.

At the MIC’s April 13 meeting, Tom Hauske, principal engineer in PJM’s performance compliance department, reviewed the joint proposal to revise Manual 15: Cost Development Guidelines that came out of discussions at the Cost Development Subcommittee (CDS).

The CDS initially brought two proposals for first reads to the October MIC meeting. (See “Start-up Cost Offer Development,” PJM MIC Briefs: Oct. 6, 2021.) But a vote on the proposals was postponed to allow more discussions and have stakeholders reach consensus on a single proposal.

Manual 15 currently allows the start-up costs for combined cycle units to include fuel costs after generator breaker closure and synchronization to the grid, a feature not available to other unit types, such as steam and nuclear plants. The revisions align start-up costs for all units with a soak process, or units that use steam turbines.

For units with a soak process, including steam, combined cycle and nuclear units, some of the soak costs are included in the start-up costs from PJM’s notification to the “dispatchable output” and from the last breaker open to the shutdown process.

Units that don’t have a soak process, like combustion turbines and reciprocating engines, maintain the status quo, with start-up costs that include costs from the time of PJM’s notification to the first breaker close and from the last breaker open to the conclusion of the shutdown process.

“We’re not implementing soak time at this point,” Hauske said. “We’re just allowing generators that have a soak process to include those costs in the startup cost.”

The revisions feature several other changes to Manual 15 to provide additional guidance and clarification, Hauske said, including equations to calculate start-up costs, station service calculations for units with and without a soak process and unit-specific parameter limits on includable costs.

Manual 15 currently allows generators to include an additional labor cost in their start-up costs, Hauske said, but generators already are permitted to include the labor cost in the unit’s capacity offer through its avoidable cost rate (ACR). The proposal calls for eliminating the labor cost language in the tariff and Operating Agreement offer cap sections and the start-up cost calculation so all the operating labor is includable in the ACR.

Hauske said PJM will provide a six-month window for implementation to allow market sellers the opportunity to have their fuel costs or net generation used for the offset to be reviewed by the Monitor prior to the proposal going into effect.

The proposal will be presented as a first read at the April 27 Markets and Reliability Committee meeting.

Stability Limit Changes

Zhenyu Fan, senior engineer in PJM’s real-time market operations, provided education and a first read of conforming updates to Manual 11: Energy & Ancillary Services Market Operations and Manual 28: Operating Agreement Accounting regarding stability limits in markets and operations.

In early 2021, stakeholders endorsed PJM’s proposal on stability limits capacity constraints that included language limiting lost opportunity cost (LOC) credits for any generation reduction required to honor the stability limit in the RTO. The limiting of LOC compensation led to debates among PJM members. (See “Stability Limits Endorsed,” PJM MRC/MC Briefs: Jan. 27, 2021.)

FERC ruled in February that PJM is within its rights to refuse (LOC) payments to generators that are temporarily required to limit output to prevent loss of synchronization and additional strain on the system during transmission outages. (See FERC: PJM Right to Block Gen Stability Limit Payments.) The tariff changes take effect June 1.

Zhenyu said PJM will use a new generator output constraint to enforce the stability limit for real power megawatt-only limits. He said the shadow price of the constraint will not be included or reflected in locational marginal pricing (LMP).

To provide greater transparency, Zhenyu said PJM added a new section to Manual 11 related to stability limits that describes the modeling, clearing and reporting process on the stability limit in the market. Updated language related to stability limits in Manual 28 included additional clarification that LOC credits are not paid for megawatts associated with a stability limit reduction.

Paul Sotkiewicz of E-Cubed Policy Associates said he disagreed with FERC’s decision on LOC payments. Sotkiewicz also disagreed with the proposed manual language, saying the changes don’t provide for “workarounds or a reconfiguration change” between PJM and the transmission owners to find ways to eliminate a stability problem.

“There’s a very easy workaround that eliminates the transient stability problem, and what I find alarming here is that there’s not going to be any effort made to do that,” Sotkiewicz said.

Phil D’Antonio of PJM asked Sotkiewicz to elaborate on a possible solution in the manual language. D’Antonio said his perspective has been that adjusting the system in an outage situation resulting from instability and limitations can end up “pulling the system apart even more.”

Sotkiewicz said he would want to look for “easy switching options” that are available to “eliminate the transient stability limit.”

“We’ve actually been in conversations with PJM operations, and we have found those solutions in the past,” Sotkiewicz said.

D’Antonio said he’ll take the suggestion back to PJM’s operations group for additional discussions before the next MIC meeting.

The committee will be asked to endorse the manual revisions at the May MIC meeting.

Intelligent Reserve Deployment Changes

Damon Fereshetian, senior engineer in PJM’s real-time market operations, provided a first read of additional updates to Manual 11 and Manual 28 related to intelligent reserve deployment (IRD).

Stakeholders in December endorsed a PJM proposal to improve the deployment of synchronized reserves during a spin event. (See “Synchronous Reserve Endorsed,” PJM MRC/MC Briefs: Dec. 15, 2021.)

The proposal created an IRD, which is a security-constrained economic dispatch (SCED) case simulating the loss of the largest generation contingency on the system and for which approval of the case will trigger a spin event. The proposal included taking the megawatts of the largest generator contingency and adding them to the RTO forecast to simulate the unit loss. PJM can then flip condensers and other inflexible synchronized resources cleared for reserves to energy megawatts and procure additional reserves to meet the next largest contingency.

Fereshetian said Manual 11 changes include the addition of new language that an approved IRD case “supersedes” any other approved real-time SCED cases for the same target time to be used as the reference case for the locational pricing calculator (LPC). In the verification section, PJM added clarifying language that the response to a synchronized reserve event is “based on the resource following dispatch instructions and is capped at the expected response.”

Manual 28 included minor clarifying changes.

The MIC will be asked to endorse the revisions at its May meeting.

Manual 29 Revisions

Natasha Holter, manager of PJM’s market settlement operations, provided a first read of revisions to Manual 29: Billing as part of the periodic review.

Holter said there were no “substantive changes” in the manual language and mostly included updates to terminology and reference materials.

Several new subsections were added to the manual, Holter said, including one called “Billing Notifications” that features language providing guidance on how to obtain notifications for billing statements. Another subsection, “Billing Adjustments,” added language to describe what a billing adjustment is and how to identify one.

Stakeholders will be asked to endorse the revisions at the May MIC meeting.

Mass. Democrats Take on ISO-NE over MOPR

Several big voices in Massachusetts and D.C. politics are turning up the heat on ISO-NE as FERC considers the grid operator’s proposal to delay elimination of its contentious minimum offer price rule (MOPR) by two years.

In a speech outside ISO-NE headquarters last week, Sen. Ed Markey lambasted the organization as secretive, part of an “oil and gas conspiracy,” and standing in the way of the transition to clean energy.

“Instead of giving us the green light for our clean energy revolution, ISO New England is proposing to send us on a detour,” Markey said. “By proposing to delay the elimination of a rule that puts fossil fuel generation ahead of cleaner, cheaper alternatives, ISO New England is risking reliability and cost savings for residents across Massachusetts.”

Known for his affinity for wordplay and developing new acronyms, the senator said the MOPR should be called “Minimizing Our Potential for Renewables,” and that ISO-NE should be called the “dependent” system operator because “it’s dependent on gas and oil.”

“They have been in the past, they are today and their rules say they want to be in the future as well,” Markey said.

Markey’s speech also elicited support from Department of Energy official Jigar Shah.

“Time to find solutions instead of holding up clean energy projects waiting for more studies,” tweeted Shah, director of the DOE Loan Programs Office.

The two-year “transition” to eliminating the MOPR from ISO-NE’s capacity market, now in front of FERC for a decision, has received a high level of scrutiny from environmental advocates, elected officials and the renewables industry who have questioned ISO-NE’s claims about reliability worries stemming from an influx of renewables and possible corresponding retirement of merchant generators. (See ISO-NE Sends MOPR Filing to FERC, Teeing up Big Decision)

In an email to RTO Insider, ISO-NE spokesperson Matt Kakley defended the process that produced the proposal.

“Our robust, federally-approved stakeholder process includes the ISO, the energy industry, representatives from the New England states and advocacy groups. ISO New England’s proposals are fully examined and discussed before undergoing review by our federal regulator prior to implementation,” Kakley said.

Markey’s claims of conspiracy, Kakley added, are “so outlandish they do not warrant a response.”

“In addition, we are independent of the resources competing in the wholesale markets and do not favor any resource type over another. In fact, ISO New England employees work every day to ensure that all energy resources can compete in the market, can interconnect safely to the regional power grid and can operate reliably,” he said.

A Senatorial Plea to FERC 

Markey also wrote a letter, along with Sens. Elizabeth Warren (D-Mass.) and Bernie Sanders (I-Vt.) calling on FERC to reject the filing and force ISO-NE to immediately remove the MOPR.

“At the very moment when New England should be fully embracing the transition to renewables and the related socioeconomic opportunities, this decision to undermine state actions and renewable energy deployment is a terrible and ill-timed mistake,” the senators wrote. 

They specifically called on federal regulators to use their authorities under Sections 205 and 206 of the Federal Power Act to “require immediate reform” of the MOPR.

“In doing so, FERC will signal that renewable energy should be allowed to fully and freely compete in wholesale markets,” they wrote. “This will ultimately lead to lower prices for household customers and facilitate our overdue and necessary transition to a decarbonized electricity grid.”

Experts have said that FERC could respond to the filing in several possible ways, including accepting it, rejecting it outright or sending it back with a finding that the status quo is unjust and unreasonable and an explicit order to immediately terminate the rule.

Extra Large PG&E Battery Project Goes Live

A major battery storage project built by Pacific Gas and Electric (NYSE:PCG) and Tesla (NASDAQ:TSLA) is ready to help California deal with the reliability problems it encountered in the past two summers, PG&E said Monday.

The utility said its 182.5-MW Elkhorn Battery facility had been “fully energized and certified for market participation by” CAISO earlier this month. The project’s 256 Tesla Megapack battery units sit on 33 concrete slabs on Monterey Bay and can discharge 730 MWh of electricity for up to four hours, providing energy and ancillary services to the grid.

“We are ushering in a new era of electric system reliability and delivering a vision into the future for our customers with the commissioning of the Tesla Megapack system in Moss Landing,” PG&E CEO Patti Poppe said in a news release. The utility owns and will continue to operate the units, it said.

The Elkhorn facility now ranks among the world’s largest battery energy storage systems (BESS), and it sits beside the No. 1 largest, Vistra’s (NYSE:VST) 400-MW Moss Landing facility, along with Vistra’s gas-fired Moss Landing Power Plant.

Moss Landing’s racks of non-Tesla batteries were shut down after overheating incidents in September and February triggered fire alarms, set off sprinklers and melted equipment.

“Vistra is in the process of conducting repairs, commissioning facility systems and implementing enhancements to improve the original design of the facility,” the company said in its initial findings on the September incident, released in late January about two weeks before the second incident occurred.

PG&E purchases Moss Landing’s output, along with energy from four other large BESSes: the 200-MW Diablo Storage System in Contra Costa County, the 60-MW Coso Battery Storage in Inyo County, the 63-MW NextEra Blythe system in Riverside County and the 50-MW Gateway system in San Diego County. All went online in the last two years.

Batteries for Reliability

In June 2021, the California Public Utilities Commission ordered PG&E and the state’s two other large investor-owned utilities, Southern California Edison and San Diego Gas & Electric, to procure 11.5 GW of new resources in the next three years to head off shortfalls.

It ordered the IOUs and other load-serving entities to purchase another 3 GW of additional capacity through supply- and demand-side programs to prevent shortages during potentially extreme heat waves in the summers of 2022 and 2023. (See CPUC Orders Procuring 3 GW of Capacity.)

The transition from fossil fuels to clean energy in California and other Western states has increased wind and solar generation while coal and gas plants have retired.

Reliability problems arose during Western heat waves in 2020 and 2021, as solar power waned on hot summer evenings but demand remained high. CAISO ordered rolling blackouts in August 2020 and declared energy emergencies both years.

Responding to the CPUC orders, PG&E said it hopes to have 3,300 MW of in-state battery storage under contract by 2024. More than 955 MW of that is already connected, and about 1,400 MW of storage capacity is scheduled to come online in 2022 and 2023, it said. PG&E won approval from the commission Thursday to contract with nine more proposed battery storage projects, totaling 1,600 MW, that could start operating between 2024 and 2026.

CAISO said it has added more than 2,400 MW of battery storage since the 2020 blackouts and expects to add 2,100 more by June.

The ISO posted a video in March on “California’s historic embrace of battery storage to support the grid as we transition to a carbon-free system.”

“Last summer was a pivotal moment for battery storage, and we felt it was important to document the story and to share our experiences and the lessons we learned,” CEO Elliot Mainzer said in a statement on the video.

“The potential of lithium-ion batteries had been talked about and anticipated for a long time,” he said. “Now they are a central part of our toolbox to make sure that supply and demand are balanced, and the system remains reliable even during the most challenging conditions.”
