Texas PUC Rejects Possible ‘Fraudulent’ Loan Application

Texas regulators have rejected the second-largest project from its portfolio of potential generation resources that would be built with state funds.

The Public Utility Commission said Sept. 4 that a project put forward by Aegle Power had failed the due diligence portion of the Texas Energy Fund’s loan-application process. The project’s developer had said NextEra Energy was a party to the application, but the Florida company told the PUC that it was not involved.

“Please be advised that NextEra’s name was submitted in the Aegle application without NextEra’s knowledge or consent,” General Counsel Mitchell Ross wrote to the commission in a letter filed Sept. 3. “NextEra is not seeking funding as part of the TEF Program, is not participating in the project for which NextEra was named, and hereby requests that NextEra be immediately removed from PUCT records as a sponsor for the Aegle Power project.”

Doug Lewin, Stoic Energy Consulting’s principal, came across the letter while searching regulatory filings in PUC dockets and raised its profile on social media.

“Not a great start,” he posted on X, formerly known as Twitter.

It gets worse. Lewin discovered that Aegle’s CEO, Kathleen Smith, had pleaded guilty in 2017 for embezzling a “significant” amount of money from a company that was trying to build a power plant in Corpus Christi, Texas.

“It was not like they created some crime in Europe. It was in Texas on a power plant,” Lewin told RTO Insider.

Smith was president of Chase Power Development, which cited low gas prices and difficulty in securing environmental permits when it abandoned the $3 billion Las Brisas Energy Center project in 2013 and said it was going out of business. The plant was to burn petroleum coke from nearby oil refineries.

The Aegle project supposedly would have built a combined cycle facility in the Rio Grande Valley with a nameplate capacity of 1,260 MW. It was among the 17 applications selected for further review as part of a $5 billion loan program intended to add thermal generation to the ERCOT grid. (See PUC Shortlists 17 Projects for Loans from Texas Energy Fund.)

PUC Executive Director Connie Corona said the commission is “still a long way” from selecting the companies that will receive TEF loans.

“Proposed projects that have reached this stage have only met the initial requirements for applications,” she said in a statement. “We have a multistage application and verification process that gets more rigorous at every step to ensure only financially sound applicants with viable projects receive these loans.”

The commission said it will pursue at least a 10% repayment from the TEF contractor, Deloitte. The advisory services firm conducted the first review of applications.

In testimony before the state Senate Finance Committee on Sept. 5, PUC Chair Thomas Gleeson said the commission had learned the previous week that one of the TEF applications was “perhaps submitted with potentially fraudulent information.”

“While I am absolutely certain that this this project never would have gotten funded, and we assumed that some projects would fall out … it is still unacceptable to have moved this forward,” he told the committee. “I think it is clear that our contractor needed to do better in their initial review of this company and that our staff needed to hold our contractor more accountable for that review. … We should have asked a lot more questions about these companies.”

State Sen. Charles Schwertner (R), who authored the bill authorizing the TEF (Senate Bill 2627), called the developments “disappointing” and promised “hard questions” during a Texas Energy Fund Advisory Committee joint oversight hearing with House members Oct. 8.

Schwertner said the request for a contract administrator included “very specific requirements of the … contract administrator regarding fraud prevention.” He also raised issues around NextEra’s involvement in the application, noting that their letter to the PUC “doesn’t say they didn’t have a relationship” with Aegle.

Gleeson told Schwertner that NextEra has a nondisclosure agreement with Aegle. He said that in a call with the company Sept. 4, he asked NextEra to “reconsider their stance” and break the NDA.

“They informed me that they were not changing their stance,” Gleeson said.

“I don’t know what’s going on with NextEra about their relationship here with this applicant, Aegle Power, but I want to know,” Schwertner said. “We’re going to get to the bottom of it, whether it requires subpoenas to [legislative committees], but this is unacceptable that we have large publicly traded companies as well as new entrants with questionable backgrounds.”

“This doesn’t smell right. I’m not believing everything I’m hearing,” said Sen. Joan Huffman (R), the committee’s chair and a member of the TEF Advisory Committee.

The PUC says it expects the due diligence review to take up to eight months. Commission and Deloitte staff will verify each project’s details, including participating companies, financial viability, construction plans, interconnection capabilities, ability to complete the project and ability to pay back the taxpayer-backed loans, the PUC said.

While the lawmakers questioned the initial vetting process, Stoic’s Lewin said his concerns lie with the 10 GW of dispatchable thermal generation that the TEF is designed to construct.

“It looks to me that they were trying to pick a whole lot of different generators. Seventeen different projects, but there are not really 17 difference credible thermal energy generation developers in Texas,” Lewin told RTO Insider. “Somebody really wants [new thermal capacity] to be 10 GW. I want to see the study that says 10 is the number. Where’s the data, where’s the study that says 10 is the magic number?”

Lewin advocates for microgrids and backup power packages that can be used at the local level, such as during the recent Hurricane Beryl, and funding for wires infrastructure and generation facilities in Texas’ non-ERCOT regions. He said the two TEF programs could be at risk should the push for 10 GW of thermal generation encroach upon their funding.

“You have credible power companies out there,” Lewin said. “Let them do their projects and stop fixating on 10 GW.”

WestTEC Committee OKs Plan for ‘Actionable’ Tx Study

The Western Transmission Expansion Coalition’s (WestTEC) steering committee on Sept. 5 unanimously approved the plan that will underpin a Western transmission study designed to stimulate development of interregional projects over the next two decades.  

“The study plan approval was the result of many months of collaboration within the WestTEC committees and with community and regional partners,” Sarah Edmonds, CEO of Western Power Pool, which is coordinating WestTEC, said in a press release. “We are grateful to these partners who have helped get us this far and to the Western Electricity Coordinating Council as a major sponsor of our upcoming work.”  

WestTEC’s transmission study plan, jointly facilitated by WPP and WECC, is an industry-led effort to address long-term interregional transmission needs as the grid expands and climate change accelerates. Approval of the plan commences the study itself, which will take place over the next two years.  

The main objective is to create an “actionable” transmission study by conducting integrated planning analysis across the Western Interconnection that produces 10- and 20-year transmission portfolios. (See Group Looks to Create ‘Actionable’ West-wide Transmission Plan.)  

The effort is voluntary, intended to respond to the “widely recognized concern that current transmission planning frameworks in the West do not result in the identification of sufficient transmission solutions to support the needs of the future grid and that interregional transmission planning can be strengthened,” the study plan reads.  

The study horizons focus on evaluating transmission requirements in 2035 and 2045, with the goal of prioritizing “flexible and scalable transmission solutions for nearer term needs to help better position the system for efficient long-run expansion.”  

Assuming the system will evolve based on current trends, existing policies, generation projections and load forecasts, the study will primarily reference the WECC 2034 anchor dataset, utility integrated resource plans, state agency data and other non-proprietary data sources.  

The study isn’t meant to replace existing transmission planning processes or alter FERC Order 1920 — the landmark ruling requiring regions to undergo long-term transmission planning — but to complement them.  

Notable features of the transmission study include:  

    • a study footprint spanning the Western Interconnection, as well as interties connecting the Canadian provinces of Alberta and British Columbia.  
    • load-growth forecasts that capture the increasing demand for electricity.  
    • resource forecasts that result in a generation mix that meets state policy requirements, reflects clean energy goals and accounts for voluntary procurement of clean energy.  
    • consideration of multiple planning scenarios to reflect the inherent uncertainties of long-range planning.  
    • an integrated approach to identifying transmission portfolios, with an emphasis on identifying transmission needs not addressed by other planning efforts.  
    • regional partner engagement and governance.  
    • credible and objective study execution through an independent consultant team.  

The study’s goals include addressing reliability and commercial and economic efficiency by ensuring the footprint has sufficient transmission capacity to meet future energy needs while reducing congestion, identifying a plan that complies with NERC reliability standards and enabling operational efficiency. 

WestTEC also aims to address affordability by unlocking the benefits associated with a coordinated transmission portfolio that can enable greater diversity in supply and demand. Other goals include increasing visibility into the combined capabilities and requirements of the study footprint and addressing cost allocation.  

If those goals are met, backers of the plan hope the study will serve as input into local and regional planning processes; initiate bilateral negotiations and development activities; facilitate engagement with local communities, tribal nations and regulators; provide meaningful data; and a serve as a resource to developers, utilities and state regulators.  

Study Limits

While WestTEC backers anticipate the effort will “fill many planning gaps currently present in the West,” they also acknowledge its limits.  

The study won’t provide a comprehensive list of all needed transmission infrastructure, nor will it capture all the infrastructure needed to maintain economic and reliable operations.  

It also won’t focus on identifying infrastructure needed to address pre-existing reliability issues within a single transmission-owner area, or on resolving lower-voltage thermal issues “reasonably expected to be addressed through existing interconnection, local or regional planning processes, even if such issues are present on transmission infrastructure that would otherwise be in the scope of the assessment.”  

Additionally, the study offers a “point in time” view of transmission needs, meaning the projects explored by WestTEC will be implemented in response to evolving needs that will be clearer over time.  

While WestTEC emphasizes the plan will not be a “singular transmission solution in the West,” participants are confident the study will help ensure reliable and sustainable grid operations in the future.  

The 10-year horizon study is already underway and is expected to be complete by September 2025. The 20-year study will begin in spring 2026, with the full report slated for September 2027.  

“With this milestone, there’s good momentum right now, and we need to keep our partners engaged and keep it going,” Edmonds said.

NERC, Industry Discuss IBR Issues in Technical Conference

This week’s technical conference to address industry objections to NERC’s proposed standard on inverter-based resources, the ERO’s first ever after invoking section 321 of its Rules of Procedure, is likely to be followed by “a lot more” in the near future, NERC staff said. 

NERC’s Standards Committee hosted the conference Sept. 4-5 at the Westin Washington, DC Downtown hotel following a directive from the ERO’s Board of Trustees at its meeting last month. (See “Board Invokes Standards Authority to Meet IBR Deadline,” NERC Board of Trustees/MRC Briefs: Aug. 15, 2024.) ERO staff had planned to hold the gathering at NERC’s office in D.C. but moved it to the Westin to accommodate the high level of stakeholder interest. 

The board invoked its section 321 authority to order the meeting after PRC-029-1 (Frequency and voltage ride-through requirements for IBRs) failed to receive approval in its most recent formal ballot round. FERC ordered NERC in October 2023 to submit reliability standards addressing several aspects of IBR performance, including ride-through protection, by Nov. 4, 2024, and ERO leadership feared that the normal standards development process might not move quickly enough to meet the commission’s deadline. 

During the two-day technical conference, NERC staff presented on the background of the standard, including FERC’s order and the work of the standards development team. Industry stakeholders also took part in panels with NERC staff discussing their issues with the proposed standard and possible ways to address them. 

In one panel, representatives from original equipment manufacturers laid out some of the challenges they saw with meeting NERC’s proposed requirements, particularly in existing inverters manufactured before the standard becomes enforceable. Scott Karpiel, principal applications engineer at SMA America, mentioned that while he thought meeting the new requirements should be easy for utilities buying newer inverters, entities using older hardware might have trouble because of the legacy equipment’s firmware limits. 

Another panel saw representatives from NERC, utilities and industry groups discuss strategies for implementing the ride-through standard alongside others resulting from FERC’s assignment that have already received industry approval. These include PRC-028-1 (Disturbance monitoring and reporting requirements for inverter-based resources) and PRC-030-1 (Unexpected inverter-based resource event mitigation). 

Howard Gugel, NERC’s vice president of regulatory oversight, said entities concerned about implementing the new requirements could consider turning to trade organizations for aid. 

“Working by yourself, you might come up with something, but as a community, if you come up with a solution, there’s a power that could occur there,” Gugel said. “I think there’s a wealth of information that can be tapped there as you get involved in those things.” 

Soo Jin Kim, NERC’s vice president for engineering and standards, observed that the ERO has “several other projects on the horizon” that are also the subject of FERC directives. She highlighted Project 2023-07 (Transmission system planning performance requirements for extreme weather), which has been working to meet FERC’s directive to submit a standard by December that addresses performance concerns of transmission equipment in cold weather. 

The team for Project 2023-07 has produced a new standard, TPL-008-1, which has failed to reach industry approval in two formal ballot rounds. In the most recent round that closed Aug. 22, the standard received a weighted segment approval of just over 18%, well below the two-thirds majority needed to send it to the board for approval. (See Cold Weather Standard Fails Second Ballot.) Kim said this project, and others facing FERC deadlines, may need to follow the path laid out in section 321. 

“For some of the major projects that we see on the horizon — high-priority projects, things that require a lot of coordination [and] where there’s major gaps in information that the team just did not have at its fingertips — I do think that these events are [very] fruitful,” Kim said. “The department is [not just] going to … look at this from the standards perspective, but also on the engineering side, we have talked about doing more technical conferences generally, even before we get to some of the standards development steps.”

Collaboration Key to Managing Growing Western Load, Panelists Say

Collaboration among stakeholders is crucial to maintaining Western grid reliability in the face of increasing demand posed by large loads such as new data centers, speakers said Sept. 4 during a webinar hosted by WECC.

Representatives from Elevate Energy Consulting, the Pacific Northwest Utilities Conference Committee (PNUCC) and the Grant County Public Utility District in Washington participated in the webinar. The panelists discussed the challenges of integrating large loads in the Western Interconnection.

According to PNUCC’s Northwest Regional forecast for 2024, electricity demand is projected to increase from approximately 23,700 average MW in 2024 to about 31,100 aMW in 2033, an increase of over 30% in the next 10 years.

“That is an increase of 7,000 average MW, or enough electricity to power seven cities the size of Seattle,” said Crystal Ball, PNUCC’s executive director. She noted the increase in demand is  primarily from three things: data center development, high tech manufacturing growth and electrification.

“But really, we see it coming from these companies developing large data centers in the Pacific Northwest,” Ball added.

Grant County has been dealing with the increase in large loads for some time, according to Shane Lunderville, business development manager for the county’s publicly owned utility.

“We’ve had data centers for the last 10 years and a lot of growth that has not stopped,” Lunderville said. “We have averaged in just industrial growth between 5 to 7% per year of that growth, and we’re not seeing it slow down.”

Ball said the increased demand for electricity is a sign of economic growth opportunities. However, it also poses significant reliability challenges, such as integrating large loads while adhering to efforts to reduce carbon emissions.

“One misstep really could lead to cascading consequences,” according to Ball. “It’s really the reliability of the power system that is at risk during this transition while meeting this increasing demand for electricity.”

She added that stakeholders must work collaboratively and focus on proactive solutions.

Kyle Thomas, vice president of compliance services at Elevate Energy Consulting, agreed, saying that “all parties have to be at the table.”

“Doing one thing on the grid actually involves many different departments … because it’s so interconnected, it’s so involved, and the data centers is no exception,” Thomas said. “So, we need policy, we need regulatory, we need legal, we need the engineers.”

However, according to Thomas, one issue is that data centers often have strict confidentiality rules due to the competitive space between different developers. This makes it difficult to study how to best integrate data centers while ensuring reliability, he said.

“We should still start and try and figure out where our gaps of knowledge are and partner with them to get information, get data, get models, and then learn from these real operations with monitoring data and get that cycle as fast as possible,” Thomas said.

The U.S. also could learn from other countries that have successfully brought on data centers while ensuring the reliability of the grid, according to Thomas.

“You look at Ireland and their adoption of data centers is unbelievable,” he noted. “You look at the [European Union], they have had interconnection requirements in place and policies for large loads since about 2009. We can learn from others in the collective global industry here to learn and accelerate our knowledge where it may be lacking, and we can also help others in that aspect.”

Clean Power Installations Hit Record for Second Quarter, ACP Says

American Clean Power Association on Sept. 5 released its latest Clean Power Quarterly Market Report, in which developers set a record for the second quarter with 11 GW of installations — up 91% from the same period last year. 

In all, 137 utility-scale projects went online, and they brought the cumulative nameplate capacity up to 283.6 GW across utility-scale solar, storage and wind — enough to power 70 million homes. 

The second quarter brought installations up to 19 GW across the first half of the year. ACP noted the second half usually sees higher installations, so 2024 could set a record for solar, storage and wind installations. The first half of the year beat the previous five-year average by more than 10 GW. 

“While all clean energy technologies are expanding their market share, energy storage is scaling at a stunning speed and has surpassed 20 GW of operating capacity,” ACP CEO Jason Grumet said in a statement. “With rapidly growing demand and the need to make significant strides in decarbonizing our economy, the stakes are high. Our recent progress is encouraging, but we are not moving fast enough.”   

The quarter saw California lose its crown as leading state for utility-scale solar, as Texas added 1,656 MW — bringing its total installations to a whopping 21,932 MW. Across the country, solar saw 6.7 GW installed, or 61% of overall clean energy installations. 

Storage added 2.9 GW around the country in the second quarter, which brings its total installations to 21.6 GW. 

Land-based wind saw the smallest installations among the three technologies, with 1,370 MW installed in the second quarter. But that was more than triple the capacity added in the first quarter. 

Onshore wind still represents most of the installed capacity for renewables in the country, but solar is closing the gap — at 39% at the end of the second quarter, up from 26% on Jan. 1, 2020. 

Some 32 states and the District of Columbia added clean energy capacity in the quarter, with Texas leading the way with 2,596 MW overall. California came in second, adding 1,947 MW. Of that, nearly 70% was storage, a trend that should continue because storage represents 64% of the clean capacity in the Golden State’s development pipeline. 

The clean power pipeline of projects under development is at nearly 163 GW, which is up 13% from the middle of 2023 and has been growing at 5% annually. The steady expansion of the pipeline can be attributed to storage and solar, which have grown at average rates of 12% and 3% per quarter since 2022.  

The pipeline dipped 1.5% from the first quarter due to projects entering operation and the cancellation of New York’s third offshore wind project. The decline should be short lived, with an additional 8 GW to 12 GW of offshore wind set to be added to the pipeline as states wrap up ongoing procurements. 

ACP Welcomes the 10th BOEM Offshore Wind Approval

The report was released a few hours before the Bureau of Ocean Energy Management approved the country’s 10th offshore wind project — the Maryland Offshore Wind Project, which brought total approvals by the agency to 15 GW. 

“Today’s approval of our nation’s 10th offshore wind project — a total game change from the zero projects approved before President Biden and Vice President Harris took office — shows the tremendous progress we are making to harness this economic opportunity that [benefits both] American workers and the planet alike,” White House National Climate Advisor Ali Zaidi said in a statement. “From port infrastructure upgrades and new tax credits to speeding responsible and efficient permitting, we are using every tool available to continue turbocharging this industry and delivering a clean energy future for the nation.”  

The Maryland project is planned to add 2 GW of offshore wind capacity and would supply power to the Delmarva Peninsula. Its lease area is 8.7 nautical miles offshore Maryland and about 9 nautical miles from Sussex County, Delaware. 

“In just four years, the U.S. went from zero permitted offshore wind power projects to 10, representing real progress,” ACP Vice President for Offshore Wind Anne Reynolds said in a statement. “Of these, one project is completed and five are under active construction.”

DOE Awards $430M for Hydro Maintenance

The U.S. Department of Energy has awarded $430 million to nearly 300 projects at hydroelectric facilities to enhance dam safety, strengthen grid resilience and improve the environment.

The funding, announced Sept. 5, comes from the DOE’s Grid Deployment Office through the Maintaining and Enhancing Hydroelectricity Incentive program.

The 293 projects to receive funding are spread across 33 states. Eighty-four projects focus on grid resilience, 149 are dam safety projects, and 60 are environmental improvement projects. Award amounts range from $7,200 to $5 million.

Hydropower contributes nearly 27% of the nation’s renewable electricity generation and 93% of utility-scale energy storage. But the fleet is aging, officials noted. Facilities selected for funding are on average 79 years old.

For example, Entergy Arkansas marked the 100-year anniversary of the Remmel Dam this year. The DOE awarded $1.8 million for safety improvements at the dam.

“We’re thrilled to invest in this hydroelectric fleet that is such an important part of our nation’s electric system,” Maria Robinson, Grid Deployment Office director, said during a news conference.

For the most part, the projects selected for funding through the Maintaining and Enhancing Hydroelectricity Incentive program won’t increase generation or capacity, DOE officials said.

Rather, the program focuses on strengthening grid resilience at dams through measures such as turbine or generator replacement or transformer upgrades.

Safety measures funded by the program might include improvements to emergency spillways or concrete replacement to prevent water seepage through the dam.

In addition, the program funds environmental and recreational improvements such as fish ladders or improved boating access.

Multiple Awards

Many utilities are receiving awards for multiple projects. PacifiCorp Renewable Resources was awarded $38 million for nine projects, including $5 million each for the Fish Creek pumped storage facility and Weber Dam improvements.

Pacific Gas and Electric is receiving more than $34 million for 19 projects. Among the funding is $123,289 for improvements at the Potter Valley fish hotel and $5 million for the Lower Bucks spillway restoration project.

Michigan-based Consumers Energy is receiving about $23 million for 10 projects, including $5 million each for improvements at the Rogers and Hardy spillways.

Seattle City Light was awarded about $21 million for five projects, including $5 million for dam safety at the Cedar Falls hydroelectric project.

The Maintaining and Enhancing Hydroelectricity Incentive is one of three DOE programs that fund hydroelectric projects through the Bipartisan Infrastructure Law.

Another program, the Hydroelectric Production Incentives, will provide $125 million to hydroelectric facilities for electricity generated and sold. In 2023, 66 hydro facilities were awarded $36.7 million. Applications for a second funding round are now under review.

The third program, the Hydroelectric Efficiency Improvement Incentives, will invest $75 million into hydropower facilities. In February, DOE awarded $71.5 million to 46 hydroelectric projects in 19 states.

The Grid Deployment Office will discuss the latest Maintaining and Enhancing Hydroelectricity Incentive awards during a webinar on Sept. 11 from 1 to 1:30 p.m. ET.

DOE expects to announce a second round of funding for the program next year.

‘Leaning’ Evident in BPA Response to NW Senators

CAISO’s adoption of the West-Wide Governance Pathways Initiative’s “Step 1” changes won’t overcome the Bonneville Power Administration’s objections to the governance of the ISO’s Extended Day-Ahead Market (EDAM), BPA Administrator John Hairston told U.S. senators from the Pacific Northwest.

“Our specific concern is that, with only Step 1 in place, the market governance remains under the ultimate authority of California,” Hairston wrote in an Aug. 21 letter to the senators, which has not yet been posted on the agency’s website.

Hairston’s comments were part of a broader response to a series of questions posed to him in a July 25 letter signed by Democratic Sens. Jeff Merkley (Ore.), Ron Wyden (Ore.), Maria Cantwell (Wash.) and Patty Murray (Wash.).

In their letter, the senators urged the agency to “act carefully and deliberately” before selecting a day-ahead market and to delay a “draft letter to the region” relaying its decision, previously slated for Aug. 29, until more developments play out around EDAM and SPP’s competing Markets+ offering. (See NW Senators Urge BPA to Delay Day-ahead Market Decision.)

The senators’ letter signaled a preference shared by many Western state officials, public interest groups and large energy users — and some utilities — that the region will benefit most from a single organized electricity market that includes CAISO.

It also expressed concern that BPA staff in April issued a “leaning” recommending the agency choose Markets+ over EDAM, citing the SPP market’s independent governance and overall design as primary factors supporting the opinion. The senators directed the agency to answer 14 detailed questions to clarify the reasons behind the leaning. (See BPA Staff Recommends Markets+ over EDAM.)

Inadvertently or not, the senators got one wish: In his Aug. 21 response, Hairston said BPA would delay its market decision until next year, an announcement it later would relay to its stakeholders on Aug. 25, saying both markets have “outstanding issues that require additional analysis.” (See BPA Postpones Day-ahead Market Decision Until 2025.)

But Hairston’s Aug. 21 response to the senators clearly — and understandably — shows the fingerprints of the staff that produced the leaning. It also evinces continued concerns among some parties in both the Northwest and Southwest about a market arrangement that could be dominated by California and its interests.

In response to the senators’ question about which market BPA expects “will provide the greatest improvement in grid reliability in the Northwest,” Hairston cites the benefit of the Markets+ requirement that its participating entities also participate in the Western Power Pool’s Western Resource Adequacy Program (WRAP).

“The EDAM proposal’s lack of a common resource adequacy metric makes it difficult to assess whether the market or its participants will be resource adequate in the planning horizon for the market,” Hairston wrote, adding that California’s “state-mandated” RA metrics don’t align with WRAP requirements and that EDAM will accept non-California participants that haven’t committed to the WRAP.

Responding to another question about which market would do more to reduce greenhouse gas emissions from the Northwest’s electricity sector, Hairston said Markets+ has made progress in developing GHG tracking and accounting procedures that would allow BPA’s customer base of publicly owned utilities to meet Washington’s cap-and-invest program obligations and Oregon’s “non-pricing” carbon requirements.

“Our continuing concern with CAISO’s EDAM design is that California is able to deem a disproportionate share of carbon-free market-traded resources as delivered to California, to the disadvantage of utilities in the Northwest and their ability to meet their state goals,” he wrote.

Addressing a question about the impact on the Northwest grid from “seams” between two different markets, Hairston cited BPA’s previous experience using the Coordinated Transmission Agreement with CAISO to enable several of the region’s utilities to use BPA’s transmission system to participate in the ISO’s Western Energy Imbalance Market before the agency itself joined that market.

“Bonneville expects to undertake a similar exercise if necessary to manage day-ahead market seams,” he said.

Governance Still Key

But the issue of CAISO’s state-run governance was front and center in Hairston’s response to the senators — just as in the staff leaning.

“Bonneville seeks to participate in a market that has a durable, effective and independent governance structure [that] provides fair representation to all market participants and stakeholders,” he wrote.

Hairston described the choice as being between Markets+, with its independent board of directors, and EDAM, which would fall under the “shared authority” of the Western Energy Markets (WEM) Governing Body and the ISO Board of Governors “appointed by the governor of California.”

Hairston acknowledged the progress made by the Pathways Initiative in forcing movement on CAISO’s governance. The ISO and WEM boards last month voted to approve the Pathways plan giving WEM officials “primary authority” over WEIM- and EDAM-related market-rule decisions. (See CAISO, WEM Boards Approve Pathways ‘Step 1’ Plan.)

But his response to the senators’ question about that effort illustrated his skepticism around whether the “Step 2” plan for advancing a California bill to grant the WEM Governing Body “sole authority” over the EDAM would get traction or meet BPA’s requirements.

“While we appreciate the Pathways’ sponsors optimism for a positive outcome, such efforts have repeatedly failed to secure legislative approval. It also remains to be determined what legislative conditions and constraints will continue to impede an independent governance structure,” he wrote.

Pathways backers expect to begin working with California lawmakers on a bill this fall after the conclusion of the current session. They hope to get the bill introduced and passed during the 2025 session, which starts in January.

That bill might not progress in alignment with BPA’s new day-ahead market decision timeline. The agency now plans to release its draft decision in March 2025, followed by a final decision in May.

AEU Webinar Highlights Potential Queue Improvements

Speeding up the interconnection queues is becoming more important as demand growth and the retirement of existing generators combine to cut into reserve margins around the U.S., experts said during a webinar Sept. 4 hosted by Advanced Energy United.

Grid Strategies President Rob Gramlich summarized a recent report his firm co-authored with the Brattle Group for United and the Solar and Storage Industries Institute called “Unlocking America’s Energy: How to Efficiently Connect New Generation to the Grid.”

The report’s recommendations would help developers of generation get more certainty from the interconnection process, which generators do not have when they enter the queues and put up deposits to save a place in line, Gramlich argued.

“The developers really need certainty, or else, if you don’t have it, you’ll continue to have this queue churn and projects coming in and out in order to get information,” Gramlich said.

After putting up their deposits, projects end up in a study process that is usually lengthy; then getting them built can be delayed because of required transmission upgrades, Gramlich said.

Supply chain issues are delaying both the construction of network upgrades and sometimes the generators themselves, with PJM reporting that nearly 40 GW of projects have made it through its queue but are not in operation yet.

“There’s no single answer to that, but there’s maybe a few common challenges,” said Hannah Muller, senior director of external and market affairs at Clearway Energy Group. “One is supply chain; that’s both for the actual project equipment, but also the transmission infrastructure. There’s just years [of] delay in getting necessary equipment; it’s just a function of the global economy at this point.”

Other issues include permitting and community opposition to new infrastructure; FERC and the RTOs can speed up the interconnection, but those are outside of their purview, Muller said.

FERC made changes to the baseline for queues with Order 2023, but the report and panelists argued that additional measures are needed. The commission is holding a two-day technical conference from Sept. 10 to 11 on that subject; Gramlich said it would be a good venue for helping to share best practices from the different regions.

In addition to certainty, the Grid Strategies report argues for quicker schedules and non-discrimination that guarantees a level playing field for “similarly situated interconnection customers.” Adopting an interconnection entry fee for proactively planned capacity would provide customers with significant interconnection cost certainty and address cost allocation of the upgrades identified. The report also suggests a fast-track process to use existing and already planned interconnection capacity that would prioritize the projects most ready to go live.

The interconnection study process also needs improvements to enable the fast-track process and make studies more efficient generally, the report said.

One promising way to improve the study process that is in its early stages is the use of artificial intelligence, said Kyle Davis, the Clean Energy Buyers Association’s senior director of federal affairs.

“SPP, Amazon Web Services, Pearl Street [Technologies] and NextEra [Energy] are testing out Pearl Street’s SUGAR platform to try and help organize and bring that machine-learning process to the interconnection queue analysis,” Davis said.

Testing so far indicates the technology can whittle what has historically taken three months down to as little as an hour, he added. The report discusses the pilot effort, and Pearl Street’s CEO, David Bromberg, is a witness at FERC’s technical conference next week.

The final set of modifications that the report suggests is around speeding up the transmission construction backlog to address growing constraints that hinder network upgrades. The report noted that while it did not focus on proactive transmission planning, that is key to speeding up the queues, and several transmission providers are already implementing proactive planning, while others are developing long-term planning processes to comply with FERC Order 1920.

Speeding up construction also would mean addressing supply chain issues, with which the Department of Energy could help, Gramlich said. As for FERC jurisdictional issues, it is unclear why some utilities can get network upgrades built more quickly than others; the report suggests some independent monitoring of that stage to identify why that is happening and address issues that slow down construction, Gramlich added.

Demand is growing, but supply is out there that could address it, said R Street Institute Senior Fellow Beth Garza, who is also speaking at FERC’s technical conference next week.

“Those costs eventually are borne by consumers,” Garza said. “It’s consumers that are using the electricity. They’re the ones getting value out of having the electricity. … It’s the indirect costs that consumers absolutely bear by inefficient processes.”

DOE Set to Fund 2 Energy Storage Research Hubs

Teams led by Argonne National Laboratory and Stanford University are in line for $125 million to boost their research into next-generation energy storage.

The U.S. Department of Energy announced the funding Sept. 3. It said the two Energy Innovation Hubs will accelerate development of storage technology beyond lithium-ion batteries, with a priority on use of inexpensive and abundant materials.

The Energy Storage Research Alliance (ESRA) led by Argonne will focus on new compact batteries for heavy-duty transportation and grid-scale energy storage, while the Aqueous Battery Consortium (ABC) led by Stanford will work to establish the scientific foundation for large-scale development and deployment of aqueous batteries for long-duration grid storage technologies.

If finalized, the awards will be worth up to $62.5 million each and will extend up to five years.

In its own announcement, Argonne said:

“ESRA seeks to enable transformative discoveries in materials chemistry, gain a fundamental understanding of electrochemical phenomena at the atomic scale and lay the scientific foundations for breakthroughs in energy storage technologies.”

The goal is high-energy batteries that provide days of output, do not catch fire and have decades-long service lives. They will rely on abundant materials, which may mitigate the cost and supply chain volatility associated with present-day batteries.

ESRA Director Shirley Meng said: “To achieve this, energy storage technology must reach levels of unprecedented performance, surpassing the capabilities of current lithium-ion technology. The key to making these transformative leaps lies in a robust research and development initiative firmly grounded in basic science.”

DOE said both projects also will be a vehicle for workforce development and inclusion of diversity.

ESRA Deputy Director Wei Wang said: “Cultivating a diverse workforce dedicated to safeguarding America’s energy resilience is key to ESRA’s mission. Through our strategic equity and inclusion initiatives, we plan to create a robust training ground for energy storage science from the undergraduate to postdoctoral levels.”

Stanford in its announcement said the ABC seeks to overcome the limitations facing batteries that use water as their electrolyte.

ABC Director Yi Cui explained that enormous amounts of stationary energy storage will be needed to achieve net-zero greenhouse gas emissions, and said water is the only realistic solvent available at the cost and quantity needed.

He said: “How do we control charge transfer between solids and water from the molecular to the device scale and achieve reversibility with an efficiency of nearly 100%? We don’t know the solutions to those hard problems, but with the Department of Energy’s support we intend to find out.”

The aqueous battery concept is in extensive use in the starter systems of internal combustion vehicles, but those batteries are small and rely on a toxic substance — lead acid.

Using water instead is a tall order.

“The barriers to such a new aqueous battery have stymied inventors for years,” said ABC chief scientist Linda Nazar. “In addition to stubbornly low voltage and energy density, water can corrode battery materials, become the source of undesirable side reactions, and the cells can fail after just hundreds of charge-discharge cycles under demanding practical conditions.”

Dozens of researchers working in six teams will investigate the challenge.

Stanford University and SLAC National Accelerator Laboratory lead the Aqueous Battery Consortium, and are joined by investigators from California State University, Long Beach; Florida A&M University/Florida State University’s College of Engineering; North Carolina State University; Oregon State University; San Jose State University; UCLA; UC-San Diego; UC-Santa Barbara; University of Maryland; University of Texas at Austin; and the University of Waterloo.

ESRA is led by Argonne and co-led by Lawrence Berkeley National Laboratory and Pacific Northwest National Laboratory. Partners are Columbia University; Duke University; Massachusetts Institute of Technology; Princeton University; UC San Diego; UChicago; University of Houston; University of Illinois Chicago; University of Illinois Urbana-Champaign; University of Michigan; Utah State University; and Xavier University.

DOE’s Energy Innovation Hubs are managed by the Basic Energy Sciences (BES) Program of the Office of Science. They seek to overcome key scientific barriers for major energy technologies.

ABC and ESRA build off previous BES-funded efforts, including the Joint Center for Energy Storage Research innovation hub, which ended a decade of operation in 2023 and also was led by Argonne.

MISO: 50% Peak Load Cap, Software Help Key for Crowded, Delayed Queue

MISO is adamant it should limit project proposals in future queue cycles to 50% of annual peak load to moderate its 300-GW, oversaturated queue. 

During a Sept. 3 Interconnection Queue Process Working Group teleconference, MISO’s Ryan Westphal said an annual megawatt cap, in conjunction with a tech startup’s software for study help, will allow MISO to build study models faster without the “engineering problem” of too many hypothetical overloads, network upgrades and resources exceeding load. (See MISO Sets Sights on 50% Peak MW Cap in Annual Interconnection Queue Cycles.) 

“We think that gives us the best chance of moving faster,” Westphal said of overall queue processing.  

MISO’s current queue stands at 321 GW.  

Westphal said a cap won’t hinder MISO’s resource adequacy, either. Using the queue’s historical 21% completion rate, Westphal said MISO stands to add roughly 67 GW within a few years, even with capping entrants. 

In the long run, MISO estimates 310 GW will be able to hook up to the system through 2042. Westphal pointed out that figure exceeds the 248 GW of additions by 2042 that the RTO uses in its current transmission planning scenario. Westphal said that number should allay stakeholders’ resource adequacy concerns, where a cap might restrict too many projects from connecting. 

Clean Grid Alliance’s Rhonda Peters asked how MISO plans to factor in significant new load additions in its annual megawatt cap.  

Westphal said the cap calculation will be based on peak load using MISO’s five-year out models, which should capture definite load additions.  

“Using what’s in the models as firm makes the most sense,” he said.  

Westphal also said MISO’s attempt to conquer its unwieldy queue using Pearl Street’s study software will not negate the need for a cap.  

MISO will lean on Pearl Street’s SUGAR (Suite of Unified Grid Analyses with Renewables) software to conduct screening of projects prior to conducting studies in earnest and to perform the first phase of studies in the queue.  

MISO has delayed kickoff of studies on the 123 GW of projects that entered the queue in 2023 while Pearl Street assists with modeling. When the 2024 cycle will begin is an open question, since the RTO intends to have the cap in place before it formally accepts a new cycle. (See 2023 Queue Cycle Delayed into 2025 as MISO Seeks Software Help on Studies.)  

“We have long been proponents of technology adoption in this space,” NextEra Energy’s Erin Murphy said, thanking MISO for reaching out for third-party help. However, Murphy said that if MISO and Pearl Street can achieve faster study results with more variables, that could negate the need for a megawatt cap on annual queue cycles. 

Westphal said while SUGAR may help speed up study processing, without a queue cap, MISO still would run into the familiar problem of unrealistic dispatch models overflowing with too many projects. 

Westphal said MISO still wants to return to its usual cadence of one-year queue cycles where submissions are accepted in the fall, validated through the holidays and begin studies in the new year, after MISO’s Board of Directors approves MISO’s planning models. However, Westphal added that it doesn’t make sense to accept a new queue cycle if the previous cycle isn’t far enough along in the study process.  

Last week, the Union of Concerned Scientists’ Sam Gomberg suggested MISO plan to play “catch up” on queue studies if Pearl Street’s software proves successful. He suggested MISO consider accepting multiple queue cycles in a year to get back on track.  

MISO is not entertaining using a volumetric price escalation — where developers pay fees that increase as they submit more projects for study — in lieu of a cap, as some stakeholders requested. Westphal said enacting escalating fees won’t solve MISO’s underlying “technical issue” of trying to study “load being served by too many generators.” 

“In our minds, it’s not an alternative for a cap. We still believe we need that hard cap there to get us to reasonable study parameters and dispatch [model],” he said.  

Several MISO generation developers argued that a volumetric price escalation would encourage interconnection customers to put only their best projects forward, discourage manipulation of the queue and allow small developers and co-ops an even playing field for submitting projects. 

Savion’s Derek Sunderman said MISO could police the volumetric approach by requiring large corporations to sign forms attesting to their subsidiaries. Sunderman requested that the RTO conduct a stakeholder vote to gauge whether stakeholders prefer the cap or a volumetric price escalation.  

Some stakeholders have asked MISO to consider giving developers estimated network upgrade costs at the screening stage of queue, if Pearl Street is proven effective at anticipating results.  

MISO still is drawing up a plan to reevaluate the queue cap after three annual cycles, Westphal added. A few stakeholders have asked the RTO to view the cap as a short-term measure and commit to sunsetting the cap after three years of use.  

“Unfortunately, there’s no silver bullet on the queue. It’s just constant improvement,” Westphal said. 

MISO has scheduled a special meeting Sept. 30 to discuss the queue cap again. Westphal said he hopes to present “a final go” of the queue cap by then, make a filing at the end of October and earn FERC approval by the end of the year.
