Mass., RI, Conn. Sign Coordination Agreement for OSW Procurement

BOSTON — Massachusetts, Rhode Island and Connecticut have reached an agreement on coordinating the procurement of offshore wind, Massachusetts Gov. Maura Healey (D) announced Wednesday.

Healey touted the benefits of the multi-state agreement at the American Clean Power (ACP) Association’s Offshore WINDPOWER 2023 conference, stressing the importance of regional collaboration and the potential of the agreement to benefit ratepayers.

“Through this agreement, here’s what we’re going to do: Align our procurements to leverage our collective buying power, lower project costs and maximize benefits for ratepayers across the region and increase the efficiencies and reduce project risk for offshore wind developers,” Healey said at the conference.

The Massachusetts governor added the states collectively have the authority to procure up to 6,000 MW of offshore wind capacity. According to the memorandum of understanding (MOU), the state agencies will “work in good faith to ensure that multi-state bids are considered.”

Under the agreement, multi-state bids could be extended to just two of the states, or all three. Each of the states are in various stages of the RFP processes for new procurements. Massachusetts has issued the largest solicitation of the three states at up to 3,600 MW, with proposals due in January. (See Mass. DOER Issues Draft RFP for Region’s Largest OSW Solicitation).

“Regional collaboration through this three-states MOU will not only help in advancing offshore wind projects of large scale by securing cost-effective energy prices for ratepayers — but it also provides a significant opportunity for long-term economic development,” Rhode Island Gov. Dan McKee (D) said in a press release.

The announcement — and the conference that hosted it — come at a crucial time for the region’s offshore wind industry, as supply chain constraints and high interest rates have strained existing power purchase agreements (PPA).

On Monday, Avangrid and two Connecticut electric utilities announced the termination of the PPA for the 804-MW Park City Wind project (Conn. PURA 19-12-18, see Park City Wind to Cancel PPAs, Exit OSW Pipeline). Meanwhile, the Massachusetts Department of Public Utilities approved the termination of the SouthCoast Wind PPA on Friday (Mass. DPU 20-16, 20-17, 20-18) following the termination of the Commonwealth Wind PPA earlier this summer (Mass. DPU 22-70, 22-71, 22-72, see Commonwealth Wind PPA Cancellations OK’d).

Healey doubled down on the importance of offshore wind, calling it “an anchor for our state’s short-term and long-term success,” despite the recent industry challenges.

Several speakers at the conference praised the agreement. Pedro Azagra Blázquez, CEO of Avangrid, said the agreement is necessary and “very important,” in his remarks following Healey’s.

ACP called the agreement “a bold way to drive cost efficiencies for projects across a broad swath of New England while promoting economic growth, enhancing security and driving down energy costs.”

“Procurement at this scale is exactly what industry needs to solve some of its most pressing issues,” said Liz Burdock, CEO of the Business Network for Offshore Wind, in a statement. “Big scale drives real cost reductions, fosters a pipeline large enough for new manufacturing investments and should create enough certainty to entice developers and vessel owners to enter into framework agreements that would unlock capital sitting on the sidelines.”

Throughout the conference, speakers expressed both optimism about the long-term outlook for the industry and the concern that if the current round of procurements fails to produce meaningful results, supply chain issues could push back the in-service dates of the next round of projects into the 2030s. Such a delay could significantly hinder the ability of states to meet their emissions reduction targets.

Bob Grace, president of Sustainable Energy Advantage, called the multi-state agreement “somewhere between a very big deal and not a big deal,” noting that Massachusetts, Connecticut and Rhode Island previously participated in the joint procurement of renewable energy in 2015-16. The joint procurement resulted in a mix of land-based wind and solar projects, selecting proposals totaling 460 MW.

Grace said the experience was extremely unwieldy as each state’s laws and procedures became constraints on their neighbors and was a process that many involved vowed never to repeat. He said the announced offshore wind agreement appears to learn from that experience by coordinating procurements rather than jointly procuring. He added the benefits of the agreement will hinge upon how effectively the states can work together.

“There is no way for the New England states to hit their climate goals without offshore wind,” Grace said.

While many policymakers in the region have pushed to get as much offshore wind in the project pipeline as soon as possible to reduce emissions, Massachusetts Attorney General Andrea Joy Campbell (D) has expressed concern about the size of Massachusetts’ recent solicitation.

In her initial comments on the solicitation, Campbell said timing these procurements during a period of cost increases could leave ratepayers with inflated bills (Mass. D.P.U. 23-42). The state Attorney General recommended capping the maximum procurement at 1,600 MW instead of 3,600 MW, with smaller, more frequent procurements to follow the solicitation.

This strategy “likely would help moderate the pace of offshore wind procurement and protect ratepayers from the volatility in the current market,” Campbell said.

While announcing the states’ agreement, Healey stressed the importance of federal support for offshore wind to keep costs manageable.

“A critical piece of this is how we’re able to maximize federal funding,” Healey said, highlighting the administration’s application for an up-to-$250 million matching grant from the U.S. Department of Energy for transmission upgrades that would help connect offshore wind to the grid.

Healey called on conference attendees to help push the federal government for more support for the offshore wind industry.

“This is a federal administration that has purported to be about a clean energy transition,” Healey said. “Hold them accountable.

Plan Seeks to Boost Prospects for New Transmission in the West

The Western Power Pool (WPP) on Monday floated a proposal to revamp transmission planning in the West with the aim of spurring development of the kind of large-scale transmission projects FERC’s Order 1000 process has failed to produce.

The proposal, which WPP laid out in a concept paper, envisions creation of a new group, the Western Transmission Expansion Coalition (WTEC), which would “explore a new approach for West-wide transmission planning that will result in an actionable transmission plan to address regional and interregional needs.”

The paper says that while the region’s current planning processes overseen by NorthernGrid in the Northwest, WestConnect in the Southwest and CAISO comply with FERC requirements, “the legal and regulatory structure upon which they were built is limited and has not resulted in the identification of new transmission solutions that result in transmission builds.

“The limited nature of regional planning also handicaps the broader West in developing inter-regional transmission solutions. To effectively address the collective needs of the grid for the future, transmission planning must be performed in a more holistic and coordinated manner, such that a plan for transmission expansion solutions can be optimized to meet a broader set of needs,” the paper says.

WPP spokesperson Kevin Langbaum told RTO Insider that participants in “informal” conversations that produced the plan included WPP, BPA, the Pacific Northwest Utilities Conference Committee (PNUCC), the Northwest & Intermountain Power Producers Coalition (NIPPC), the Public Power Council (PPC), PacifiCorp, Idaho Power, Portland General Electric, Snohomish PUD, Puget Sound Energy and clean energy advocacy group Renewable Northwest.

“At the request of leadership from the Bonneville Power Administration (BPA) in response to stakeholders’ urging and supported by leadership of several energy industry entities and utilities, an informal group formed to discuss approaches to address a widely recognized concern that current transmission planning frameworks in the West do not result in sufficient transmission solutions to support the needs of the future energy grid,” the WPP said in describing the proposal.

The concept paper defines an “actionable” transmission plan as one that would “enhance” regional and interregional reliability, “address economic efficiency and help states achieve their respective goals.” In the paper, “regional” refers to the NorthernGrid transmission planning area covering the Pacific Northwest and Intermountain West, where the proposal originated, while “interregional” denotes all three Western U.S. planning areas — CAISO, WestConnect in the Southwest and NorthernGrid — as well as BC Hydro and AESO in Canada.

Beyond the goal of creating an actionable plan that increases grid reliability and efficiency, the effort also would seek to improve “visibility and coordination” of planning across the West and “support” future cost allocation decisions, although the paper makes clear the WTEC “does not intend to formulate or prescribe a cost allocation standard” for projects.

The concept paper does not provide a technical scope for the effort but instead proposes to establish the structure that would define the scope of the effort.

“While this effort is focused on the production of an initial transmission plan, the WTEC envisions that the process could evolve into a durable, long-term function, including periodic updates and refreshed analysis,” WPP said in the paper.

Two Committees And A Task Force

The paper proposes the WTEC be organized into two committees and a task force to address technical matters around transmission planning.

At the top would be a Steering Committee “comprised of senior and executive leadership from diverse entities committed to the study effort” and “responsible for resolving and making major decisions to structure the transmission plan.”

“While the Steering Committee will make decisions informing the transmission plan, it also carries the responsibility to collaborate with other committees organized to support the effort,” the paper states.

The paper proposes the Steering Committee include representatives from NorthernGrid (including BPA and others to be named), CAISO, WestConnect (including WAPA and others), WECC, Canadian province transmission planning, NIPPC, Renewable Northwest, Interwest Energy Alliance, PNUCC, PPC and WPP. The committee also would include a “state” representative to be determined after consultation with the region’s states.

A Regional Engagement Committee (REC) would consist of representatives from various stakeholder sectors and would “be responsible for providing input and feedback on the approach for the transmission plan, as well as providing input on major decisions informing the transmission plan,” according to the paper.

The REC would consist of two members each from: the Steering Committee, federal power marketing agencies, non-federal power marketing organizations, independent power producers, independent transmission developers, public interest groups, ratepayer advocacy organizations, industrial electricity customers, state agencies and tribes. It also would include four members each from investor-owned utilities and consumer-owned utilities.

The paper also proposes a Technical Task Force that would identify transmission study scope and approach, “including but not limited to renewable energy zones, resource expansion, electrification and load data, and scenario development, including extreme event scenarios, phasing of study outcomes and recommendations, data protocols, etc.”

The task force would consist of technical staff from Steering Committee members, Pacific Northwest National Laboratory, the Northwest Power and Conservation Council, WPP, and merchant and independent transmission developers. It also would include an independent consultant with expertise in transmission selected by the Steering Committee.

The concept paper also outlines the intent for “periodic communications and public webinars to provide stakeholders from the public with input and feedback opportunities.”

WPP is seeking feedback on the proposal and has posed a series of questions for stakeholders regarding the proposed participation structure of the WTEC, the composition of its committees and its plans for broader engagement with the region. Comments are due by Oct. 31 and should be sent directly to WPP CEO Sarah Edmonds at sarah.edmonds@westernpowerpool.org.

Northeast Stakeholders Push Transmission Planning, Siting Reform

BOSTON — The clean energy transition will require an all-out push on transmission planning and siting reform, government officials and energy experts told stakeholders on Friday, outlining some of the major challenges and opportunities of the region’s energy transition.

Several speakers at Raab Associates’ New England Electricity Restructuring Roundtable emphasized the importance of interregional and intraregional transmission planning to ensure the grid can handle increased amounts of variable clean energy and higher demand from electrification.

“Transmission planning is vital if we are going to deliver the clean energy transition,” said Mike Calviou, senior vice president for National Grid.

Calviou spoke about his experience working for National Grid in the United Kingdom, which has successfully deployed nearly 14 GW of offshore wind operational capacity, compared to just 48 MW in the U.S. He said the U.K. now is facing congestion issues on the transmission system, hurting both rates and the further deployment of clean energy.

To avoid escalating congestion costs in New England as offshore wind capacity increases, Calviou said the region should focus on anticipatory investment and coordinated planning, instead of the current just-in-time approach.

Maria Robinson, director of the U.S. Department of Energy Grid Deployment Office, outlined some of the federal funding opportunities available for transmissions projects, including the $10.5 billion Grid Resilience and Innovation Partnerships Program and the $2.5 billion Transmission Facilitation Program.

Robinson noted, however, that “throwing money at the problem is not necessarily the way to solve these issues around particular backlogs on the transmission system,” and called for a targeted approach rather than blunt force.

She highlighted the office’s work on National Interest Electric Transmission Corridors, which can increase funding opportunities and streamline the permitting process within designated corridors.

“When it comes to corridors, we’re taking a very different approach than the Obama administration,” Robinson said, noting that the approach of the Obama administration focused on designating “large swaths of land” as corridors. She said the current approach is more targeted, relying on developers and utilities to indicate exactly where corridors would be helpful.

“I think it will be both more legally defensible as well as useful to actually get some of these designated,” Robinson said.

Clarke Bruno, CEO of the transmission developer Anbaric, touted the potential benefits of an offshore grid to minimize the onshore impacts of deploying offshore wind at scale. (See Brattle Study Highlights Benefits of Offshore Grid.)

An ocean grid would be “costly, but less costly than the alternatives,” Bruno said.

Permitting and Siting Reform

Government officials from New York and Massachusetts also discussed permitting and siting reform, a topic which has been gaining steam in the commonwealth.

Earlier in the week prior to the conference, Gov. Maura Healey (D) signed an executive order creating a state Commission on Clean Energy Infrastructure Siting and Permitting to make recommendations on permitting and siting reform (See Massachusetts Announces Permitting And Siting Reform Commission.), while top legislators have indicated the topic is a key priority in the current legislative session. (See Checking in on Clean Energy at the Mass. Legislature.)

Houtan Moaveni, executive director of the New York Office of Renewable Energy Siting (ORES), spoke about some of New York’s recent successes in expediting the development of clean energy. The ORES was created by the legislature in 2020, consolidating the state’s siting and environmental review processes for large clean energy infrastructure.

Moaveni said the office has helped usher in the “most rapid pace of renewable energy project approvals in the state’s history.” He emphasized the importance of the preapplication process, creating clear guidelines for project developers and engaging with impacted communities early in the process.

“Building local support for these projects is just as important as getting regulatory approvals,” Moaveni said, adding that he has spent much of his time traveling to meet with communities to understand their needs and ensure local benefits — including discounted electric rates.

“It is possible to streamline and expedite the permitting process for generating facilities without undermining communities and environmental protections,” Moaveni said.

Elizabeth Mahony, commissioner at the Massachusetts Department of Energy Resources, said the newly created permitting and siting commission has “a lot of work to do.”

“Maybe we can take a couple of pages from New York’s playbook — if it’s a good idea, we’ll steal it,” Mahony said in response to Moaveni’s presentation.

Mahony doubled down on the state’s commitment to renewable energy development, singling out solar and offshore wind as key areas of growth. She highlighted a DOER report released in July on the potential for solar development that mapped solar potential across the entire state. The analysis found the state has the potential for about 50 GW of highly rated solar capacity.

“We can be strategic about where we deploy solar and how we deploy it,” Mahony said. “We think that this information… is really a tool that we can use, that municipalities that are facing a lot of permitting issues can use, and certainly that our utilities should be using as they are planning their grid upgrades.”

Park City Wind to Cancel PPAs, Exit OSW Pipeline

Another New England offshore wind project has gone off the rails.

Avangrid on Monday announced an agreement with two Connecticut electric distribution companies to terminate power purchase agreements for its Park City Wind proposal (Conn. PURA 19-12-18).

The 804-MW wind farm is “unfinanceable” under the terms agreed on, because of subsequent sharp cost increases, the company said. It hopes to rebid Park City Wind at more favorable terms.

Park City was an important component of Connecticut’s emissions reduction/climate protection planning, and Gov. Ned Lamont (D) expressed disappointment in the turn of events. The move will likely delay the arrival of offshore wind in the state, and almost certainly increase its cost to ratepayers.

It also is the latest in a yearlong series of setbacks for offshore wind in southern New England.

With its steady winds, shallow waters, nearby customer base and deepwater ports, the region had a pioneering role in launching the industry in the U.S. Now it is feeling the blowback as the industry struggles with supply chain constraints and soaring costs.

Avangrid this year negotiated a similar exit from its PPAs in Massachusetts for the Commonwealth Wind project, again because the financial terms were untenable (Mass. DPU 22-70, 22-71, 22-72).

The Shell/Ocean Winds joint venture SouthCoast Wind bailed out of its Massachusetts PPAs for the same reason; state regulators approved the termination agreement Friday (Mass. DPU 20-16, 20-17, 20-18).

Rhode Island’s most recent offshore wind solicitation drew just one bid — the Revolution Wind 2 proposal by Ørsted — and it was rejected as too expensive.

Ørsted still has not made a final investment decision on Revolution Wind 1, although it obtained federal approval for construction and operations in late August. The company is looking for incentives to improve the financials.

Massachusetts utility Eversource Energy is in the late stages of exiting the partnership with Ørsted that has resulted in multiple wind power proposals off the New York and New England coastlines.

Even the two bright spots in New England waters — construction starting this year on the nation’s first two utility-scale offshore wind projects — have not been without hiccups. WBUR reported Monday that Vineyard Wind is behind schedule because of a spate of rough seas and foul weather. Newsday reported Tuesday that South Fork Wind’s schedule is in flux because of issues with availability of a ship needed to complete the work.

New York and New Jersey offshore wind projects are struggling with the same headwinds as these New England projects, but none has progressed beyond threats of cancellations.

Park City Wind

Park City Wind’s exit erases much of Connecticut’s offshore wind pipeline — only 304 MW from Revolution Wind 1 remains.

Connecticut Department of Energy and Environmental Protection Commissioner Katie Dykes told NetZero Insider on Tuesday that Avangrid’s exit was an unwelcome development.

“Over the last several months, DEEP engaged Avangrid, and industry experts, to understand concerns about the economics of Park City Wind and the significant near-term challenges facing offshore wind projects in general,” she said via email. “We hoped to hear proposed solutions to enable the Park City Wind project to move forward while protecting Connecticut’s ratepayers and respecting our state’s commitment, embodied in statute, to conduct competitive procurements. Unfortunately, these discussions failed to materialize in a proposal that met these goals. DEEP is working with the state’s utilities to ensure that bidders into future solicitations — including our upcoming solicitation for offshore wind — are able to deliver completed projects at the prices they offer and face steeper penalties if they do not.”

Charles Rothenberger, climate and energy attorney for environmental advocacy group Save The Sound, said the financial pressures on wind power developers are real. The goal now is to preserve a viable offshore wind program without transferring too much of those pressures to utility ratepayers.

“Given the really substantial financial commitments these companies already have made … what it tells me is this was not simple gamesmanship on the part of the industry, if anybody thought that,” he told NetZero Insider.

Rothenberger added that the inflation adjustment mechanism included in the next solicitation should go both ways and require developers to refinance at a lower cost when interest rates decrease.

Avangrid addressed the situation in a statement Monday.

“One year ago, Avangrid was the first offshore wind developer in the United States to make public the unprecedented economic headwinds facing the industry, including record inflation, supply chain disruptions and sharp interest rate hikes, the aggregate impact of which rendered the Park City Wind project unfinanceable under its existing contracts.”

The company said it, stakeholders, and state and federal officials were unable to find common ground to preserve the PPAs.

Park City Wind LLC’s termination agreements with Eversource and United Illuminating Co. call for a combined $16.08 million in payments to the two utilities. That is substantially less than the termination penalties negotiated by SouthCoast ($60 million) and Commonwealth ($48 million) in Massachusetts.

Other Developments

In this challenging financial environment, offshore wind development in New England continues.

South Fork and Vineyard have said they plan to generate their first power this year.

Connecticut is preparing to issue a request for proposals for up to 1,196 MW of offshore wind — potentially larger than Park City, but not vastly larger. The solicitation had been scheduled tentatively for September.

The developers of SouthCoast and Commonwealth plan to bid into the latest (and largest) Massachusetts offshore wind solicitation, announced in August. As it ranks the bids on a points-based system, the state may penalize the two companies for bailing out on their previous agreements.

The Environmental Protection Agency issued its final preconstruction permit to Revolution Wind 1 on Thursday.

Rhode Island issued a Strategic Plan for Offshore Wind Jobs & Investment. Numerous offshore wind lease areas are clustered south of the Ocean State; state and business leaders hope to establish Rhode Island as an onshore hub for the offshore industry as it grows.

Rhode Island is taking another swing at drawing electricity from the industry as well. Gov. Dan McKee last week announced that the state’s largest electric utility, Rhode Island Energy, will issue a request for proposals this month for up to 1,200 MW of offshore wind capacity.

Each person quoted in the announcement stressed the word “affordability” — the issue that torpedoed the previous offshore wind solicitation.

“Rhode Island has big clean energy aspirations, and Rhode Island Energy is committed to helping achieve them,” said utility President Dave Bonenberger. “This new procurement can help advance the state’s clean energy goals and support achievement of Rhode Island’s emissions-reduction targets. We look forward to seeing how offshore wind developers can balance those goals with affordability and wider economic benefits for the state.”

NARUC, NASEO Release Solar Cyber Toolkit

A new toolkit from the National Association of State Energy Officials (NASEO) and the National Association of Regulatory Utility Commissioners (NARUC) aims to help state regulators grapple with cybersecurity concerns with distributed solar resources that “have not been fully addressed.”

The toolkit was produced by the Cybersecurity Advisory Team for State Solar (CATSS), which NARUC and NASEO launched in June 2020 with the U.S. Department of Energy’s Solar Energy Technologies Office. (See NARUC, NASEO Launch Solar Cybersecurity Resource.) CATSS includes experts on digital security, the electric grid and photovoltaic technologies, with leadership drawn from state-level policymakers and regulators and additional support from the federal government and private sector.

CATSS’ focus is on distributed solar because, as the document states, “less attention has been given” to it from cybersecurity efforts than to “legacy assets and bulk power” despite the “significant forecasted growth” of distributed energy resources as part of the overall generation mix. This attention deficit is particularly concerning because DERs rely on remote communication tools to a degree that traditional resources do not, meaning a successful cyberattack could lead to serious consequences.

“As the leaders in state energy policy and program development in support of their governors’ and legislators’ cybersecurity and DER goals, state energy offices are increasingly engaged in cybersecurity actions,” said NASEO President David Terry in a statement. “This toolkit will help states achieve their energy and resilience goals by creating more cyber-secure distributed energy resources.”

The kit comprises 10 tools divided into two areas of focus. The first is education and risk awareness to inform state energy officials and public utility commissions of the underlying issues around distributed solar and other DERs.

The category includes four documents. Photovoltaic solar engineering and system overview covers the components of a local solar panel network and their communication with each other and grid controllers. The Standards quick guide provides relevant standards from regulators like FERC and NERC, along with industry groups such as the Institute of Electrical and Electronics Engineers.

Assessing solar cybersecurity is a list of discussion prompts for energy officials and commissions to discuss cybersecurity issues with utilities. The final tool in the section, Hypothetical solar cyberattack scenarios and impacts, discusses “approachable, plausible scenarios of cyberattacks affecting [solar] assets and interconnected infrastructure.”

In the second set, NARUC and NASEO provide practical actions to address cyber threats. The Decision support tool for solar energy cybersecurity policy and regulation includes a probable risk assessment to help users understand the risks and ownership of a solar network’s physical assets. Next, the Case studies and model guidance tool assists states with forming working groups, a “critical first step to establishing state cybersecurity programs.”

In Cybersecurity and the solar workforce, the writers suggest competencies and skillsets that should be looked for in solar-related cybersecurity professionals, along with tactics that energy offices and commissions can use to encourage good hiring practices. Cybersecurity considerations for state procurement of solar assets offers sample language for procurement agreements, contracts and grants, as well as models for setting up state solar cybersecurity practices.

Exercise design guidance for solar cybersecurity provides recommendations for designing energy emergency exercises, drills and other solar cybersecurity-focused simulations. Finally, the last tool approaches the cybersecurity issue from the perspective of state legislatures, offering example bills for “states seeking legislative options to help mitigate these risks.”

Texas High Court to Review Decision on Uri Charges

The Texas Supreme Court has agreed to review a lower court’s invalidation of the Public Utility Commission’s emergency pricing orders during the deadly 2021 winter storm, potentially placing billions of dollars of transactions at stake.

The state’s high court granted the PUC’s petition for review Friday and set oral arguments for Jan. 30, 2024 (23-0231).

The commission in March asked the court to review the decision, reverse the judgment and either dismiss the case or rule in the PUC’s favor. It said the orders it issued expired years ago and therefore cannot be voided, and said the commissioners made “split-second decisions” necessary to help correct a market failure. (See Texas PUC Appeals Court’s Decision on Uri Transactions.)

The PUC filed its petition shortly after the 3rd Court of Appeals reversed two commission orders to keep the market’s wholesale prices at the $9,000/MWh cap during Winter Storm Uri. The court found the commission’s actions “entirely” eliminated competition and were contrary to state law. It remanded the case for “further proceedings consistent” with its ruling.

The actions resulted in $16 billion of market transactions that ERCOT’s Independent Market Monitor said were incorrectly priced during the 33 hours that followed once the grid operator stopped shedding firm load. The PUC declined to re-price the transactions. (See “Monitor: $16B ERCOT Overcharge,” ERCOT Board Cuts Ties with Magness.)

Some of the $16 billion balance has since been securitized and some participants have been paying off debts they now might not even owe. Other transactions have been settled outside ERCOT and can’t be undone, according to legal expertise.

Luminant Energy, Vistra’s generating subsidiary, filed the appeal with the 3rd Court and has been joined by Exelon. They say the commission exceeded its authority in allowing the high prices while the ERCOT grid was trying to find generation after more than 50 GW of resources were knocked offline by the storm.

Calpine, Talen Energy and TexGen Power are among the generators that support the PUC’s position.

NERC: Battery Facilities Also Vulnerable to Inverter Faults

Battery energy storage systems (BESS) may be vulnerable to the same systemic performance problems seen in several disturbances in solar generators and other inverter-based resources (IBR) over the past few years, according to a joint report released by NERC and WECC on Monday.

The 2022 California Battery Energy Storage System Disturbances report concerns two events that occurred in Southern California last year and resulted in the loss of significant amounts of BESS in the region. According to NERC and WECC, they are the first major grid events to involve battery facilities and demonstrate why grid planners “need to consider these systems in the same light as any other” IBR.

The first event began just after 6 p.m. Pacific Time on March 9, when a generator circuit breaker at a natural gas-fired simple-cycle facility in Riverside County, Calif., suffered an internal failure, causing a generator bus fault. Generator units relayed and disconnected the natural gas generators, which were producing 694 MW, and the fault was cleared after about 4.5 cycles.

At the same time, IBRs at several facilities unexpectedly reduced output by a collective 408 MW. 124 MW of this reduction was attributed to BESS. As a result, the total generation loss topped out at 1,102 MW and system frequency dropped to 59.916 Hz. In response, CAISO raised regulating unit output, and frequency returned to normal in three minutes.

The second event began at 3:06 p.m. PT when a B-phase-to-ground fault occurred on a 220 kV bus at a new BESS plant that was still undergoing testing. While the fault was cleared normally in about four cycles, it caused a further unexpected reduction of output from multiple IBRs — including both battery and solar facilities — totaling 498 MW. CAISO again raised regulating unit output to assist in the recovery from the frequency nadir of 59.924 Hz, and frequency returned to normal in one and a half minutes.

Three BESS facilities were involved in both events: a 66-MW facility containing 29 inverters, a 250-MW facility with 88 inverters, and a 70-MW hybrid solar and BESS facility with 13 battery inverters. In addition, the April event involved an additional BESS unit rated for 115 MW and containing 45 inverters.

Causes of Reduction Unclear

NERC and WECC identified inverter AC overcurrent tripping and unbalanced AC current tripping as the cause of reduction for two of the battery facilities involved in the March event. The reduction in the third battery plant was caused by DC bus voltage undervoltage for two of the 13 inverters involved. Investigators have been unable to determine the reason the remaining 11 inverters tripped.

Determining the reason for reduction in the April event was more difficult because of incomplete data from three of the four BESS facilities involved. However, investigators concluded that in one of the plants — which suffered reductions in both events — inverters tripped due to a mix of AC overcurrent tripping, unbalanced AC current tripping, DC bus unbalance, half bus DC voltage max, DC bus overvoltage and high AC voltage.

According to records, five inverters tripped in the plant that was involved in only the April event. Three tripped because of unbalanced AC current protection; the cause of the other trips is still unknown. However, the report suggested record quality may still be an issue because the output of the five inverters that tripped “does not add up to the total 26 MW lost.”

The cause of tripping could not be determined for the remaining two plants because of faulty recording at one facility and a lack of metering data for the other, which is part of a multiphase project for which data at individual plants was not available.

NERC and WECC recommendations for utilities include checking for causes of tripping identified in both this and previous IBR incident reports. Generator owners should even check for causes of tripping in incidents that did not involve BESS facilities; the ERO explained that “causes … associated with solar PV resources” had been found in the most recent incident as well.

The report also warned that transmission owners and GOs should assess BESS ride-through performance during the interconnection process, while transmission planners and planning coordinators should also “conduct ride-through performance assessments … and confirm that installed equipment, performance and capabilities match those in the studied models.” NERC plans to assess the quality of performance modeling for the affected facilities.

Finally, NERC and WECC warned that the lack of data on the incident made deep analysis of the event challenging. The report noted that none of the facilities involved met CAISO’s 10-millisecond recording data resolution requirements. Other “significant data quality issues” included a lack of individual facility metering, inconsistency between BESS data and CAISO data, and the tendency of monitors at several facilities to freeze recording at the onset of the fault.

IBR Issues Continuing

While the March and April events are the first significant disturbances on record involving battery facilities, the ERO has long been familiar with the sometimes-unexpected behavior of other IBRs like wind and solar generators. Just last month, NERC and WECC released a joint report on a Utah event in which nine solar facilities lost a total of 921 MW of generation. (See NERC Utah Event Report Underlines Ongoing IBR Issues.) Previous reports have detailed multiple similar events in California and Texas. (See NERC, WECC Repeat Solar Performance Warnings.)

“These events are the first faint signal that the systemic performance issues we have identified with other inverter-based technologies may very likely apply here as well,” Ryan Quint, NERC’s director of engineering and security integration, said in a statement. “Battery … systems will play a critical role during the energy transition; therefore, it is imperative that we design, study, commission and operate them in a manner that supports [grid] reliability.”

Green Jobs are Growing Far from Fossil Fuel Workers

Green jobs may be growing, but the vast majority of the 1.7 million fossil fuel extraction workers whose jobs are threatened by the energy transition will not fill them, according to a new paper in the journal Nature Communications.

Authors Junghyun Lim, Michaël Aklin and Morgan Frank found a significant mismatch between where green jobs are being created and where fossil fuel extraction workers are located and little likelihood of many relocating for those green jobs, even when skill sets match.

“The vast majority of extraction workers (98.97%) will not transition to green jobs according to our model,” they found. Even in two idealized scenarios — one where all the green jobs are co-located with fossil fuel jobs and the other where fossil fuel workers’ skills match green occupations’ skills exactly — only 13.7% and 5.5% of extraction workers respectively will transition to green jobs. “While both skill similarity and spatial distance play important roles, geospatial distance is the primary barrier to transitions,” they wrote.

Their study analyzed power plant data from the U.S. Energy Information Administration, job transition data from the Census Bureau and employment and skills data from the Bureau of Labor Statistics to look at whether those fossil fuel workers were likely to benefit from the growth in green jobs. While the study looked at green jobs in general, it also compared worker locations with two large green job sources, solar and wind plants, and found wind-related jobs were a little more likely to be close to fossil fuel workers’ current locations.

Is a Just Transition Possible?

The term “Just Transition” entered the public discourse as the energy sector began moving from fossil fuel-based energy to solar, wind and other low- and zero-carbon energy sources. The International Labour Organization defines it as: “Greening the economy in a way that is as fair and inclusive as possible to everyone concerned, creating decent work opportunities and leaving no one behind.”

For the energy industry, it’s a question of what fossil fuel workers do if their jobs go away. The U.S. coal industry, which almost halved in size between 2012 and 2020 as fracking grew, shows the impact of an unjust transition. Coal workers who lost jobs had few other opportunities, leaving some already-struggling areas in Appalachia the most economically distressed in the country.

“Large-scale labor market transitions are notoriously costly and difficult to complete,” Lim, Aklin and Frank wrote. “Accordingly, workers, unions and policymakers are seeking a ‘Just Transition’ in which fossil fuel workers receive public support to find new jobs.”

Achieving a Just Transition takes more than simply creating enough green industry jobs. “The issue is more complicated than simply the total number of job opportunities that will be created,” the authors said. “To be successful, this transition requires a high degree of skill similarity and geographical congruence between green and fossil fuel jobs — in addition to solutions for other non-economic social barriers.”

The Biden administration has been focused on green jobs growth, most recently announcing the “American Climate Corps,” a New-Deal style plan to train 20,000 young people. However, the relocation barrier may demand a more nuanced approach to assist those with established careers in fossil fuel extraction. Policies could address the issue “either by creating incentives for today’s fossil fuel workers to relocate or by stimulating new employment opportunities in the regions where fossil fuel workers currently reside,” the authors said.

Some states face a larger mismatch than others: “Several regions within Great Plains states will have green employment that is comparable to their local fossil fuel employment in 2019,” they wrote, “However, many of the regions with the greatest number of fossil fuel workers, including regions in Nevada, New Mexico, Western Pennsylvania and North Dakota, will not experience comparable green job growth.” Skills were less problematic, however. Lim, Aklin and Frank found that “some re-skilling may be required even though fossil fuel workers’ skills are better matched to green occupations than to other industries.”

Overheard at Deploy23

WASHINGTON — Every energy industry conference has its own particular buzz ― what attendees are talking about, not only on stage but in the side conversations between sessions, at lunches and receptions. At Deploy23, it was all about two questions: How can we do more and how can we do it faster?

Coming off the Earth’s hottest summer on record, the two-day conference Sept. 26 and 27 zeroed in on the public-private partnerships that will be needed to optimize the impact of every single penny of the billions in clean energy funding in the Infrastructure Investment and Jobs Act (IIJA)  and the Inflation Reduction Act (IRA).

More than one speaker said that building and maintaining a sense of urgency is critical. A recent report from the International Energy Agency calls for a tripling of renewable energy and doubling of energy efficiency improvements by 2030, along with a major ramp-up in electric vehicle (EV) and heat pump sales, to limit climate change to 1.5 degrees Celsius.

The IIJA and IRA funds, while unprecedented, are insufficient, said Jonah Wagner, chief strategist for the Department of Energy’s Loan Programs Office (LPO), which cosponsored the event with the Cleantech Leaders Climate Forum.

“We have to execute,” Wagner said. “And we have to execute in a way that captures the complexity and the implications of government engaging in competitive markets and supply chains, labor, workforce and community engagement, all of it. … We have to develop a shared understanding between the public sector and the private sector and then a whole broader ecosystem around how we’re going to get there.”

In his opening remarks, White House Senior Advisor John Podesta called for private sector “ownership” on the three key issues creating a drag on clean energy deployment — permitting, supply chains and workforce.

“We need you to keep voicing support for broader permitting reform at the federal, state and local level, and we need you to take responsibility for community engagement for your own projects,” Podesta said. “Get in early, engage local leaders early; and often we can address concerns that are raised at the community level, find ways to mitigate challenges on the ground and get these projects built.”

Breaking China’s dominance over clean energy supply chains is a more complex issue. While Podesta and other administration officials typically boast about the $150 billion in private sector investments in clean energy supply chains announced since the passage of the IRA, that early money has been concentrated in certain low-hanging opportunities – electric vehicles, batteries and solar panels.

But companies need to “get creative … to invest in projects up and down the supply chain, innovate in pursuit of a circular economy,” he said.

Podesta stayed on message on workforce development, calling for good wages and benefits, apprenticeship programs and opportunities for unionization. But, according to Undersecretary for Infrastructure David Crane, the immediate need at the Department of Energy is for professionals who know the nuts and bolts of project development.

“We’re looking at having 200 to 300 projects in active development by next year,” Crane said. “The skilled workforce that we need now, and where we’re entirely dependent on the private sector, is on structuring these transactions. We need the lawyers, the financiers, the tax advisors. We need the developers that can structure these transactions.”

Communication, Collaboration, Coordination

Getting projects built often means people who disagree on some issues have to find ways to work together, said Mitch Landrieu, White House infrastructure coordinator.

Recalling his own experiences as mayor of New Orleans, rebuilding the city in the wake of Hurricane Katrina in 2005, Landrieu said creating a “virtuous cycle of success” for infrastructure development required alignment of federal, state and local government, along with the private, nonprofit and community sectors.

“It’s about setting up what I call a mousetrap, the scaffolding of government where not only are we trying to do a thing, but how we’re trying to do it is coordinated — so, communication, collaboration, coordination,” Landrieu said. “If, for example, we get in a fight with a red state governor or … a blue state mayor, or the mayor and the governor are not on the same page, it will slow down our ability to move stuff to the ground because government is kind of an essential part of the spine in partnership with the private sector.”

Landrieu also argued for a broad definition of “infrastructure,” encompassing bridges, broadband and childcare.

“If you sit in a room of all women ― CEO all the way down to the person who’s cleaning the floor ― and you ask them what’s the most important thing that they need to actually show up and do that work, they’ll say childcare ― 100%,” he said. “So, my brain goes with ― childcare is infrastructure ― because if you can’t have people that do it, you can’t build stuff.”

Whether for clean energy or childcare, the foundation of public and private partnerships, he said, is “a commitment and then a willingness for everybody to show up and find common ground by pushing away the extremes and staying focused” on shared goals.

‘Getting Scrappy’

A “fireside chat” on electric cars and buses as grid assets explored both the opportunities that managed charging and virtual power plants (VPPs) present and the challenges of working with utilities to get charging stations and manufacturing plants interconnected.

Light-duty electric vehicles (EVs) typically use about 12 kWh of power a day, but when fully charged, their batteries have a much larger capacity, said Patrick Bean, director of infrastructure policy and business development at Tesla.

“So, there’s a lot of opportunity and diversity in [when people] charge … and their cars are typically sitting either 23 hours a day, 22 hours a day,” he said. “It’s a great opportunity to optimize that charging behavior for the best off-peak time, low-carbon times.”

Tesla has been piloting virtual power plants that aggregate capacity from its residential Powerwall energy storage units, and it recently launched another pilot in Texas offering Tesla EV owners a flat monthly rate of $25 for unlimited charging scheduled by the company for off-peak hours between 10 p.m. and 6 a.m., he said.

Customers can enroll via a cell phone app, “so it’s something we’re trying to make very digestible, very easy for customers to understand because if it gets too complex, they’re going to say, ‘This is too much,’” Bean said.

California–based Zum is offering school districts electric transportation — buses, vans and passenger vehicles — as a service, with apps so parents can track when their kids will be home from school.

School buses are “the largest mass transit system in the U.S.,” getting 27 million students to and from school each day, said founder and CEO Ritu Narayan, and their set schedules and evening, weekend and summer availability make them perfect for electrification and managed charging applications, like VPPs.

But, Narayan said, “the challenges are various. … The first step to that is optimizing the entire system and application, and second is establishing of the entire ecosystem, right from the manufacturers to the charging infrastructure to establish the aggregation around it” so Zum can be a one-stop shop for school districts seeking to electrify fleets.

On the interconnection side, working with utilities has become a critical part of Bean’s work at Tesla, as the company looks to expand its factories and charging networks and runs into the multiyear timeframes utilities often set for distribution system upgrades and interconnection.

As Tesla looks toward exponential growth in EV sales, he said, it can be “really hard to build utility infrastructure at an exponential rate, and I hope we can try it … because there are a lot of no-regrets investments [in] infrastructure that we know are going to be necessary. …

“There’s a lot that can be done just from a process perspective and better coordination … and just getting scrappy and coming up with new ideas to get infrastructure built,” he said, pointing to a recent example in which Tesla was able to get a new energy storage factory interconnected in 12 months.

The challenge, Bean said, is getting utilities and industry trade groups to “realize and understand that what has worked in the past is not going to work going forward. So, we need to change the processes together. …

“This is not a distributed grid versus a central grid,” he said. “Seven or eight years ago, there were concerns about a ‘utility death spiral.’ Now we’re just trying to figure out how can we support double-digit load growth, and that’s going to take a lot of coordination between the central grid and the distributed grid.”

Getting to Scale

JB Straubel, founder and CEO of Redwood Materials, knows all about scaling a business. The former cofounder and chief technology officer at Tesla, says the U.S. EV and battery supply chains have a long way to go, which is part of why he started Redwood, which recycles lithium-ion batteries to produce the critical minerals needed for EV production.

Tesla received a $465 million loan from the LPO in 2010 and finished paying it back in full by May 2013, according to the agency website. Earlier this year, Redwood received a conditional commitment from the LPO for a $2 billion loan to help it expand its plant in Nevada.

But, Straubel said during an on-stage conversation with LPO Director Jigar Shah, “I think it’s underappreciated, especially by some of the … early investment community and a lot of startups, how difficult it is to achieve scale. It’s a whole new category of problems.

“Supply chains break, geopolitics come into it. [Challenges] rise to a whole new magnitude in terms of what you’re doing when you do 100 times as much of it,” Straubel said. “It requires a different set of engineering skills and a different set of business skills.”

With a series of recent announcements on new EV and battery manufacturing facilities across the U.S., “it’s sort of tempting to feel like we’re almost there,” he said.

“But we really looked at the objective numbers on where we are on supply chain onshoring or even just supply chain geopolitical security … it’s not very far along,” he said. “Building out that robust supply chain, making sure we are being strategic ahead of time about where we invest, to kind of [look] at where the puck is going — it is just going to be critical.”

While Redwood is producing lithium and nickel, Straubel said, “until there is an entire EV supply chain, there’s nothing to do with it. … If I had a pile of lithium sitting here on the stage and went to go sell it, where do we think all the buyers would be?”

Draft Environmental Statement Prepared for Maryland OSW

Federal regulators have completed their environmental review of a Maryland offshore wind plan, moving the potential 2.2-GW project one step closer to final approval.

The Bureau of Ocean Energy Management will publish the draft environmental impact statement on US Wind’s proposal in the Federal Register on Oct. 6, starting a 45-day public comment period.

The comments will be considered as BOEM prepares the final environmental impact statement, which typically has been followed closely by the decision on whether to approve construction and operation.

Lease Area OCS-A 490 was awarded in 2014 to US Wind, which is owned by Lenexa S.p.A., a subsidiary of Toto Holding S.p.A. and Apollo Global Management. The 46,970-acre lease area is near the Delaware-Maryland border on the Delmarva peninsula.

US Wind proposes to install up to 114 wind turbines with up to 2.2 GW of combined nameplate capacity as close as 10 miles offshore, with export cables making landfall and interconnection in Delaware.

The company thus far has proposed two phases — the 300 MW MarWin and the 808 MW Momentum Wind — and secured offshore renewable energy certificates for both from Maryland. It also plans to create an offshore wind component factory at a former steel mill near Baltimore.

“This is the most significant step forward in the history of Maryland offshore wind,” US Wind CEO Jeff Grybowski said in a news release Friday. “BOEM’s draft environmental impact statement sets us on a path toward starting construction on our offshore wind projects in 2025, putting Maryland’s goals that much closer to reality. We are proud to be the first to deliver this clean energy to Delmarva and look forward to the day we can get steel in the water.”

The draft EIS for the Maryland Offshore Wind Project is similar to others BOEM has prepared for the profusion of offshore wind farms proposed off the Northeast coast — it presents a range of possible adverse and beneficial effects that construction and operation could have.

As with the other studies, the Maryland draft EIS predicts an adverse impact on the fishing industry, the critically endangered North Atlantic right whale and scientific research.

The adverse impact could be major once the cumulative effects of all the other proposed wind farms are factored in. A major adverse visual impact also is predicted.

Minor to moderate beneficial impacts also are predicted in the draft EIS. Seals and toothed whales, for example, might have better feeding conditions near the turbine tower foundations. Air quality might improve to some degree, and birds might derive minor benefit from improved foraging opportunities.

Sea turtles likely would suffer moderate negative effects but recover completely once the factors causing those effects cease.

The draft EIS and its appendices are available on BOEM’s website.
