DOT Yanks $679M in Funding for Offshore Wind Ports

The U.S. Department of Transportation has terminated $679 million in funding commitments for a dozen port and shoreline infrastructure projects planned to serve the offshore wind sector. 

The announcement Aug. 29 is the latest in a long series of policy and regulatory moves thwarting renewable energy broadly and offshore wind specifically. 

While some actions target existing projects and proposals, others — such as port infrastructure — also are forward-looking and could make it that much harder to restart offshore wind development in U.S. waters under a future administration. 

Transportation Secretary Sean Duffy repeated the frequent speaking points of Trump and his cabinet when he announced the “doomed offshore wind projects” would not be getting this financial support. 

“Wasteful wind projects are using resources that could otherwise go toward revitalizing America’s maritime industry,” he said. “Joe Biden and Pete Buttigieg bent over backward to use transportation dollars for their Green New Scam agenda while ignoring the dire needs of our shipbuilding industry.” 

By far, the largest funding withdrawal announced Aug. 29 was the $426.7 million allocated in 2024 for a terminal in Humboldt Bay, Calif., to support the floating offshore wind arrays California hopes to place off its coast. 

The other projects that saw grants withdrawn or terminated were: 

    • Sparrows Point Steel Marshalling Port Project, $47.4 million 
    • Bridgeport Port Authority Operations and Maintenance Wind Port Project, $10.5 million 
    • Wind Port at Paulsboro, $20.5 million 
    • Arthur Kill Terminal, $48 million 
    • Gateway Upgrades at the Port of Davisville, $11.3 million 
    • Norfolk Offshore Wind Logistics Port, $39.3 million 
    • Redwood Marine Terminal Project Planning, $8.7 million 
    • Salem Wind Port Project, $33.8 million 
    • Lake Erie Renewable Energy Resilience Project, $11.1 million 
    • Radio Island Rail Improvements, $1.7 million 
    • PMT Offshore Wind Development, $20 million 

The Humboldt Bay funding came through DOT’s Nationally Significant Freight and Highway Projects program; the other 11 grants were through the Maritime Administration’s Port Infrastructure Development Program. 

Duffy said DOT chose the 12 projects as part of its review of obligated and unobligated awards made through all discretionary grant programs. He said where possible, the terminated funding will be recompeted to address critical port upgrades and other core infrastructure needs. 

The DOT and its Maritime Administration, he said, now are focused on “rebuilding America’s shipbuilding capacity, unleashing more reliable, traditional forms of energy, and utilizing the nation’s bountiful natural resources to unleash American energy.” 

The funding termination is in some ways redundant, as the Trump administration has mounted a multipronged, multiagency effort to halt all offshore wind development. 

But if the funding cuts succeed in slowing and halting construction of offshore wind port facilities, this would slow future development, as well — should anyone ever try to restore the promise and potential that lay before the U.S. offshore wind sector just a few years ago. 

The road map that once included thousands of turbines producing dozens of gigawatts by the early 2030s has been eviscerated, along with the federal subsidies that would have made the huge cost of a buildout more bearable for ratepayers. 

Seven months into the second Trump administration, investing in a workforce, specialized equipment, a manufacturing base, and a supply chain now is a challenging prospect. 

With the port funding cuts announced Aug. 29, one more piece of the puzzle is harder to place. 

The Oceantic Network criticized DOT’s announcement. The trade association’s CEO, Liz Burdock, said: “The Trump administration is weakening our country’s national security and destroying good-paying jobs by pulling critical funding designed to update our aging maritime infrastructure. 

“Offshore wind port development upgrades facilities and capabilities that serve multiple industries; however, by selectively limiting infrastructure investments and removing mandated agreements in energy and shipyards, the administration is stalling essential development that delivers on shared priorities of national security and energy dominance, and signals to the investment community the U.S is not safe place for investment.” 

She added: “The U.S. offshore wind industry has sparked $5.1 billion in port funding and created more than 6,000 jobs, making this critical infrastructure mission ready for a variety of roles. It’s also expanded tax revenue for seaside communities where port assets were idle or underused for decades. This political action from the administration is another targeted attack on American jobs and American taxpayers, which will raise electricity prices for millions across the U.S. and put thousands out of work.”

PacifiCorp Moves Forward with Oregon Renewable RFP

Oregon regulators have approved PacifiCorp’s plans to issue a request for proposals for renewable resources — with a condition that the company accept bids for resources with conditional firm transmission.

The Oregon Public Utility Commission voted 3-0 on Aug. 26 to approve the RFP. The solicitation is for power purchase or energy storage agreements of five to 20 years, for resources that are online by the end of 2029.

The proposed RFP sparked a debate between PacifiCorp and stakeholder groups about whether resources dependent on conditional firm transmission should be eligible to bid.

PacifiCorp has never allowed resources with conditional firm transmission to participate in its RFPs, Rick Link, PacifiCorp’s senior vice president for resource planning and procurement, told the commission.

“It’s not called ‘firm’ for a reason,” Link told the commission.

The circumstances that may trigger transmission curtailment are unique to each conditional firm agreement, PacifiCorp said in an OPUC filing. And the fact that resource contracts may last as long as 20 years increases the uncertainty.

“These unique conditions for curtailment introduce imprudent and unnecessary risk in planning for reliable operations,” the filing said.

The Northwest & Intermountain Power Producers Coalition (NIPPC) and Renewable Northwest argued in favor of allowing bidders that plan to use conditional firm transmission.

“This could substantially increase the bid pool given the sizable queue of projects waiting to be granted long-term firm service at BPA,” Renewable Northwest said.

According to NIPPC, Bonneville Power Administration (BPA) offers two types of conditional firm transmission. In one option, BPA may curtail service up to a set number of hours. Alternatively, service curtailment may occur under specific system conditions.

But in reality, BPA rarely curtails conditional firm service, NIPPC said.

In addition, NIPPC said, BPA will lift the conditions on its conditional firm service when transmission expansion projects are completed.

“PacifiCorp, along with other utilities like Portland General Electric Company and Avista, need to be more proactive and innovative in the increasing[ly] transmission constrained world,” NIPPC said, while noting that PGE has allowed conditional firm transmission service in recent RFPs.

Growing Constraints

In approving a 2022 RFP, the Oregon commission asked PacifiCorp to analyze potential ways to include conditional firm bids in its next RFP.

“Increasing constraints on the transmission system, particularly on the west side of the PacifiCorp system, make it important to begin to more seriously consider alternative transmission products that may deliver a significant portion of the value that some resources offer the system,” the commission wrote in the 2022 order.

But PacifiCorp remained opposed to including conditional firm transmission for resources in its 2025 RFP.

The company said that under rules for the Western Power Pool (WPP) Reserve Sharing Group, any resource procured that uses conditional firm transmission would require PacifiCorp to hold 100% contingency reserves. PacifiCorp wouldn’t have access to WPP reserves in the event of the loss or curtailment of conditional firm transmission.

The Reserve Sharing Program is different from WPP’s Western Resource Adequacy Program (WRAP).

And conditions leading to curtailments are more likely when market demand is highest, PacifiCorp said, “which may necessitate the procurement of unspecified market purchases at an elevated price and with the associated assignment of emissions.”

Despite PacifiCorp’s arguments, the commission ordered the company to accept bids using conditional firm bridge, number of hours or system conditions transmission service in its 2025 RFP. The company will work with an independent evaluator to develop a framework for evaluating those bids alongside firm transmission bids.

2nd Phase Possible

The commission’s order leaves the door open for a second phase of the RFP, perhaps in 2026, in the event that questions are resolved around the Boardman-to-Hemingway (B2H) transmission line.

B2H, a partnership between PacifiCorp and Idaho Power, is fully permitted. Idaho Power said on its website that it hopes to break ground on the project in 2025, with an in-service date of 2027. B2H is a 500-kV line that will run about 290 miles from the Longhorn substation near Boardman, Ore., to the Hemingway substation in Idaho.

PacifiCorp included B2H in the preferred portfolio of its 2021 integrated resource plan. At the time, the company expected it would be able to redirect transmission rights with BPA to have a point of receipt at Longhorn, allowing B2H to serve existing load in its West balancing authority area (PACW), according to a report from OPUC staff.

But in 2022, BPA said the redirect requests would need to be evaluated in a cluster study process that had been paused.

PacifiCorp expects B2H to be completed, “but at this time, it is not known when the redirect requests [with BPA] will be granted, when redirect requests might be effective and how much it might cost.”

PacifiCorp noted that its RFP doesn’t prohibit bids from developers whose resources would use the B2H transmission line.

Decarbonization Goals

The 2025 RFP follows a commission finding that PacifiCorp’s 2023 Clean Energy Plan didn’t show continual progress toward House Bill 2021 goals. HB 2021 requires the state’s large investor-owned utilities to decarbonize their retail electricity sales by 2040.

PacifiCorp’s RFP doesn’t state the exact amount of resources that will be procured. The company will decide during the scoring process which resource quantities are most cost-effective.

But the company notes that its 2025 integrated resource plan calls for 1,570 MW of utility-scale solar, 1,400 MW of utility-scale wind resources and 320 MW of small-scale solar resources by the end of 2029, along with 781 MW of energy storage of various durations.

An earlier version of the RFP included a requirement that resources be deliverable to Oregon load. PacifiCorp said that was needed due to transmission constraints. But the company agreed to remove that requirement and will instead allow delivery to its six-state system.

Pathways Bill Will Make It to Newsom’s Desk, Author Says

After months of negotiations, the author of the California legislation needed to transform CAISO’s market into an independent regional energy market for the West is confident the state legislature will have a bill to vote on before the session wraps up in early September.

California State Sen. Josh Becker (D) introduced SB 540 in February. The bill would implement the plans of the West-Wide Governance Pathways Initiative, a multistate effort to create an independent “regional organization” (RO) to govern CAISO’s Western Energy Imbalance Market and Extended Day-Ahead Market (EDAM), the latter set to launch in 2026.

Though the legislative session is set to wrap up Sept. 12, Becker’s press secretary, Charles Lawlor, told RTO Insider that “there will be a bill before the deadline. Absolutely.”

“We’ve got lots of time to continue working on this bill,” Lawlor said Aug. 28. “It’s just a matter of finalizing it. I think everybody’s on the same page. It’s just getting it to a state where we can, you know, make sure everybody’s 100% comfortable.”

Lawlor noted that the so-called “suspense” file deadline is Aug. 29. A suspense process is part of a normal procedure in which bills are examined in the Senate and Assembly appropriation committees for their fiscal impact before being advanced to the floor.

However, because of SB 540’s significance, it will receive a rule waiver and does not have to go through the usual suspense process, according to Lawlor.

This will give parties more time to negotiate amendments and “iron out some issues and make sure that it’s properly cooked in order to get the final vote and get it across to the governor’s desk,” Lawlor said.

SB 540 passed the California Senate in June and was set for a first hearing in the state Assembly’s Utilities and Energy Committee on July 16. But the hearing was delayed until after the summer break because several organizations withdrew their support unless lawmakers amended the bill. (See Calif. Pathways Bill Delayed After Orgs Withdraw Support, While Newsom Signals Backing for Effort.)

In a letter, the coalition said it opposed an amendment creating a new Regional Energy Market Oversight Council responsible for ensuring CAISO’s participation in the regional energy market “serves the interests of the state.” (See Amended ‘Pathways’ Bill Boosts — and Complicates — Calif. Protections.) The new council would be authorized to mandate withdrawal if those interests are compromised.

The coalition requested lawmakers remove the amendment, stating “the language in this section mandates the withdrawal of California entities from the market without exception or discretion, which is unacceptable.”

The coalition also urged lawmakers to remove revisions to California’s Renewables Portfolio Standard Program and restrictions on a future market, noting entities in Colorado, New Mexico and Idaho are undecided about whether to join EDAM or SPP’s competing day-ahead market alternative Markets+.

‘Poison Pill’

The legislature resumed the 2025 session Aug. 19 after a monthlong summer recess.

Since then, California Gov. Gavin Newsom has voiced his support for SB 540, urging the legislature to pass the proposal. In a recent statement, Newsom said, “Over $1 billion in economic benefits to our state is on the line.” (See Newsom Renews Call for Passage of Pathways Bill.)

Assembly Speaker Robert Rivas has also said he supports “a voluntary, regional power market.”

Advanced Energy United was one of the organizations that pulled its support in July. The trade association’s California lead, Edson Perez, told RTO Insider in an email that legislators say “they understand the importance of establishing a robust regional market to unlock $1 billion per year in energy cost savings.”

“However, there’s still a gap in understanding the urgency,” Perez said. “We keep reinforcing that it’s now or never. With a competing market moving forward, we risk watching those savings evaporate if we don’t act this year.”

Meanwhile, Jan Smutny-Jones, CEO of the Independent Energy Producers Association, former chair of CAISO’s Board of Governors and a current member of the Pathways Initiative’s Launch Committee, said he’s “optimistic.”

However, Smutny-Jones said the Regional Energy Market Oversight Council “acts as a poison pill.”

“It does not have the support of the whole coalition,” he added. “It would be problematic within the Western market, so we need to get that out of the bill. But other than that … things are pretty smooth.”

China Cyber Threats Continue, Agencies Warn

Malicious cyber actors associated with China continue to exploit security vulnerabilities to infiltrate information technology systems used by critical infrastructure operators in the U.S. and by its allies, a new warning from security agencies in multiple countries says. 

The advisory, published Aug. 27 on the website of the Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency (CISA), is based on investigations conducted in multiple countries through July 2025, along with findings from industry. It was co-signed by CISA, the National Security Agency, the FBI and the Department of Defense’s Cyber Crime Center, along with counterparts in Australia, Canada, New Zealand, the United Kingdom, the Czech Republic, Finland, Germany, Italy, Japan, the Netherlands, Poland and Spain. 

According to the advisory, advanced persistent threat (APT) actors have pursued malicious cyber operations “linked to multiple China-based entities” against global targets, mainly in the telecommunications sector, since at least 2021. The agencies noted that the cybersecurity community has associated several groups with this activity, some of which may be different names for the same actors. Among these are Salt Typhoon, Operator Panda, RedMike, UNC5807 and GhostEmperor. 

The APT actors have “considerable success” using publicly known common vulnerabilities and exposures (CVEs). Agencies recommended that defenders prioritize CVEs involving devices from Ivanti, Palo Alto Networks and Cisco because they are known to have been exploited in the past; however, they noted that software from other providers, such as Microsoft, Fortinet and Nokia, also may be targeted. 

Even devices of people outside the threat actors’ sectors of interest may be targeted if the actors believe they can provide pathways to attack primary targets, the advisory said. Attackers can “leverage compromised devices and trusted connections or private interconnections (e.g. provider-to-provider or provider-to-customer links) to pivot into other networks.” 

APT actors then maintain access to target networks via several different techniques: 

    • Modifying access control lists to add IP addresses, thus bypassing security policies by establishing threat actor-controlled addresses as trustworthy. 
    • Opening standard and non-standard ports to expose different services, which “supplies multiple avenues for remote access and data exfiltration.” 
    • Enumerating and altering configurations for other devices in the same group, when possible. 
    • Creating tunnels between network devices to allow covert data transmission that blends in with normal network traffic. 
    • Setting up containers on compromised devices “to stage tools, process data locally and move laterally within the environment” while staying undetected because activity “within the container [is] not monitored closely.” 

The agencies encouraged cybersecurity staff at critical infrastructure organizations to carry out threat hunting activities to search for malicious activity and, if discovered, report to relevant agencies and regulators. Because the threat actors try to maintain persistent, long-term presence in target networks through several means of access, defenders “should exercise caution when sequencing defensive measures to maximize the chance of achieving full eviction.” 

Organizations also should keep in mind that APT actors often monitor compromised mail servers and network administrator accounts to see if their activity has been detected and try to keep information about their threat hunting secure from compromise, the advisory said. 

Other recommendations include regularly reviewing network device logs and configurations for evidence of unusual activity, disabling outbound connections from management interfaces to reduce lateral movement between network devices, disabling all unused ports and protocols and changing all default administrative credentials. 

“CISA and our partners are committed to equipping critical infrastructure owners and operators with the intelligence and tools they need to defend against sophisticated cyber threats,” CISA Acting Director Madhu Gottumukkala said in a statement. “By exposing the tactics used by [Chinese] state-sponsored actors and providing actionable guidance, we are helping organizations strengthen their defenses and protect the systems that underpin our national and economic security.”

ISO-NE Open to PFP Changes Following NEPGA Complaint

Responding to a complaint about “serious flaws” in ISO-NE’s Pay-for-Performance (PFP) design, ISO-NE said it is open to capping the balancing ratio used to calculate PFP payments at 1.0 to prevent capacity resources from being required to provide more power than their capacity supply obligations (CSOs).

Multiple generation companies, associations and municipal utilities supported the New England Power Generators Association (NEPGA) complaint and the proposed solution. Consumer advocates and the New England states expressed support for the general concept that generators should not be required to provide more power than stipulated in their CSOs (EL25-106).

NEPGA’s complaint stems from an ISO-NE capacity shortfall event on June 24, in which New England experienced its highest peak load in over a decade. ISO-NE estimates that PFP payments associated with this event totaled over $114 million. (See Extreme Heat Triggers Capacity Deficiency in New England.)

The RTO’s PFP mechanism compensates resources for performing beyond their obligations during scarcity events, while charging these costs to underperforming resources with CSOs. The amount of power that capacity resources are required to provide during shortage events is determined by the balancing ratio, which equals the region’s capacity requirement divided by the total amount of available capacity.

During the June 24 event, the balancing ratio exceeded 1.0 for the first time in the region’s history, averaging 1.031 over the three-hour scarcity period. This required capacity resources to provide power in excess of their CSOs, costing capacity resources about $25.6 million.

In a Section 206 complaint submitted by NEPGA to FERC following the event, the association argued that ISO-NE should be required to cap the balancing ratio at 1.0 to prevent “improper charges” on capacity resources. (See NEPGA Seeks Relief for ‘Improper’ Pay-for-Performance Costs in ISO-NE.)

NEPGA also took issue with ISO-NE’s method for allocating stopped losses for underperforming resources. ISO-NE’s PFP rules include stop-loss provisions capping the total charges an underperforming resource can accrue each month. ISO-NE allocates the under-collection of charges caused by the stop-loss limit to all capacity resources that have not hit their limit.

NEPGA argued that these costs should not be socialized among capacity resources and that the under-collection instead should be deducted from the credits paid to performing resources.

Stakeholders including RENEW Northeast, the Electric Power Supply Association, LS Power, FirstLight Power and the Massachusetts Municipal Wholesale Electric Co. supported NEPGA’s filing in comments submitted to FERC prior to the Aug. 21 deadline.

“The proposed changes are not only reasonable but essential because they eliminate penalties on perfectly performing resources and preserve durable, risk-balanced price signals for future scarcity events,” wrote LS Power.

The New England States Committee on Electricity (NESCOE) and a coalition of consumer advocates from five of the six New England states offered general support for the concept of capping the balancing ratio.

“NESCOE does not take a position on whether or not the commission should grant or deny NEPGA’s complaint or whether or not the commission should order NEPGA’s requested relief,” the states wrote. “However, NESCOE does agree with NEPGA on the general principle that a capacity resource should not be held to a performance standard that exceeds its capacity supply obligations.”

The states also echoed NEPGA’s concern that penalizing perfectly performing capacity resources “will eventually either disincentivize resources from participating in the Forward Capacity Market or cause higher risk premiums, which in turn increases both reliability risks and prices.”

The consumer advocates took a similar stance, and encouraged FERC, ISO-NE and stakeholders “to develop a solution that (1) retains the existing insulation of load from direct financial costs of CSCs [capacity scarcity conditions], and (2) avoids the incorporation of unnecessary and potentially substantial risk premiums into future capacity supply offers due to the now material possibility that a capacity resource could be financially liable for failure to overperform during a CSC.”

They noted they generally are “wary of any rule or market design that could broadly disincentivize participation in the capacity market,” and that, “in a time of increasing demand forecasts and already increasing capacity product prices, the region cannot afford the financial or reliability ramifications of a short capacity market.”

ISO-NE did not endorse any changes to the PFP methodology but said it “would not oppose an order from the commission to cap the balancing ratio at one … so long as adequate time is provided for the ISO to evaluate and make other necessary changes to the Forward Capacity Market rules so that the capping does not create other problems.”

The RTO wrote that capping the balancing ratio likely would not “materially undermine” incentives for resources to perform during capacity scarcity events.

It acknowledged that many suppliers are not capable of providing power in excess of their CSOs and conceded NEPGA’s argument that “the risk of the balancing ratio going above one was discussed only as a theoretical possibility, and that suppliers very well may not have accounted for it as a result.”

However, ISO-NE opposed NEPGA’s complaint and proposal regarding the allocation of stopped losses.

It argued that all resources with CSOs “potentially benefit from the stop-loss mechanism because — in addition to limiting a supplier’s net financial losses — it enables a supplier to know its maximum loss exposure prior to participating in the Forward Capacity Auction, and to communicate its maximum loss exposure to third parties with which it may do business, such as external entities providing financing.”

While ISO-NE argued that NEPGA failed to demonstrate that the allocation of stopped losses is not just and reasonable, it acknowledged NEPGA’s proposal to adopt PJM’s cost allocation methodology may be a viable alternative. The RTO said that “implementing such a replacement rate is feasible under the 180-day compliance timeline.”

Vitol, which operates as a power marketer in New England, opposed NEPGA’s complaint in its entirety, arguing that NEPGA failed to demonstrate that the current rules are not just and reasonable.

“NEPGA cannot escape the fact that the PFP program FERC approved in 2014 was designed to impose a share-of-system obligation on capacity resources during scarcity events, and that it was expressly recognized that the balancing ratio could exceed 100%,” Vitol wrote. “The PFP design feature at issue in the complaint was debated, and it was approved by the commission.”

Vitol noted it does not hold capacity commitments in the region, and that it earned PFP credits by importing power to the region during the scarcity event. It argued that NEPGA’s proposed changes “would harm reliability in New England by diluting incentives for suppliers to deliver energy in scarcity circumstances when it is most needed.”

Clean Energy Investments Tapering Off in Mid-2025

Clean energy investments plateaued in the second quarter of 2025 and the pipeline of new project announcements has contracted sharply, a new report shows. 

In an Aug. 28 update, the Clean Investment Monitor said U.S. clean energy and transportation investment totaled $68 billion for April-June 2025, down 0.3% from the preceding quarter but up 1% from the same quarter a year earlier. 

Individual segments within the broad category showed wider fluctuations: 

    • Retail consumer purchases and installations totaled $34 billion, 6% more than the preceding quarter but 3% less than a year earlier. 
    • Industrial decarbonization and utility-scale clean energy investments totaled $23 billion, 13% more than the preceding quarter and 7% more than a year earlier. 
    • Manufacturing investments totaled $11 billion, 15% less than the preceding quarter and 19% less than a year earlier.
    • The Clean Investment Monitor is a joint effort of Rhodium Group and MIT’s Center for Energy and Environmental Policy Research. 

The data in the Clean Investment Monitor update has been influenced by the pro-fossil, anti-renewable policy changes President Donald Trump has made since his return to office in January. A notable development in the second quarter of 2025 was the debate and enactment of the One Big Beautiful Bill Act, which spelled out just how significantly certain clean energy and transportation initiatives would be harmed. 

The number and scope of new projects announced during the second quarter gives an indication of how these policy changes were received: 

    • Utility-scale clean-energy announcements totaled $21 billion, 51% lower than the first quarter. 
    • Industrial decarbonization announcements totaled $2 billion, 17% lower than the first quarter and 38% lower than a year earlier. 
    • Manufacturing project announcements totaled $4 billion, 59% lower than the first quarter and 44% lower than a year earlier. (Manufacturing project cancellations totaled $5 billion, exceeding the value of new announcements for the first time.) 

The report places total investment in new clean energy generation and technology manufacturing facilities at $351 billion in the three years since enactment of the Inflation Reduction Act in 2022 and indicates $517 billion worth of announced investments have yet to be spent. 

The authors note that OBBBA will affect the clean energy investment landscape. 

“The tax credit eligibility changes may influence how quickly announced investments materialize [into] actual capital expenditures,” they write. “The early sunset for EV, heat pump and distributed energy consumer tax credits could reshape the composition of U.S. clean investment, which has been strongly driven by the retail segment, in the quarters ahead.”

New Data Show Queues Shrank in 2024 as Reforms Implemented

FERC has processed the first round of Order 2023 compliance filings, and the latest round of interconnection queue reforms is being implemented. Some new data indicate the efforts are starting to work. 

A recent analysis from consulting firm Wood Mackenzie found that grid operators as a whole in 2024 processed 33% more interconnection agreements than they did in 2023. At the same time, they saw 9% fewer new requests and a 51% increase in withdrawals of non-viable projects. That has helped reduce queue lengths. 

Interconnection capacity agreements reached historic highs in 2024, with 75 GW approved. Through July 2025, grid operators had approved an additional 36 GW. That’s on pace to match 2024’s record, Wood Mackenzie said. 

The analysis reports that ERCOT’s connect-and-manage approach continues to work, leading to the highest success rates and speed to interconnection in the country. ISO-NE takes second place. Wood Mackenzie notes that the ISO-NE delay from moving serial processing to a new cluster study method means it takes four times as long to sign an interconnection agreement there as it does in Texas. 

The Lawrence Berkeley National Lab also recently released a nationwide queue data set, which includes the same kind of data used to develop its “Queued Up” reports in years past. (See IRA Driving New Clean Energy as Interconnection Queue Backlogs Persist.)

LBNL’s data comes from all seven organized markets and an additional 49 non-ISO balancing areas that are home to 97% of installed generation in the country. It includes generation projects seeking to connect to the transmission system (with none seeking distribution level interconnection) through the end of 2024. 

The country’s grid operators had 2,290 GW in their queues at the end of 2024, which includes 481 GW of requests made that year. That is down from 2,598 GW overall and 908 GW of new requests in 2023. The number of older projects from previous years continued to grow, but at just 119 GW, it was at the slowest rate so far this decade. 

Nationwide, queues set a record for withdrawals (dating back to 2000), with 340 GW of projects pulling out of the process in 2024. That compares with 127.1 GW in 2023 and is well ahead of the previous annual record of 197.1 GW. 

Solar and storage continued to be the two largest technologies seeking to connect to the grid in 2024, but at around 900 GW apiece (including hybrid and standalone projects), both saw the amount in the queues drop from 2023. Natural gas generation is at a fraction of that nameplate capacity, but it saw growth on the year going from 69.4 GW of standalone projects in 2023 to 123.4 GW last year. 

Among the ISO/RTOs, MISO had the largest queue at the end of 2024, with 447.5 GW, with just over half of that coming from solar. ERCOT was second at 346 GW at the end of 2024, including 139.4 GW of solar and 116.8 GW of storage. 

CAISO had the largest queue by far in 2023, but its line was down by hundreds of gigawatts in 2024 to a still-large 272.9 GW, with storage representing 167 GW (both standalone and hybrid) and solar an additional 90 GW. 

While the number of new requests was down overall, the potential capacity in the queue continues to exceed installed capacity, with 2,290 GW in line compared to 1,322 GW of installed capacity. 

LBNL reported that most of the projects in the queue hope to connect to the grid by 2028, with 300 GW planning to connect in 2025, 371 GW in 2026, 403.6 GW in 2027 and 429.1 GW seeking interconnection in 2028. 

The data LBNL released includes five-year forecasts of demand and retirements compared to advanced projects in the queue with either signed or drafted interconnection agreements. The one region with a major gap between forecast load and new supply is PJM, which is facing significant load growth.

CPUC Fine-tunes Approach to Utility Climate Adaptation Program

The California Public Utilities Commission is looking for ways to improve a utility-oriented climate adaptation program designed to help protect the most vulnerable people and lands in the Golden State.

At an Aug. 27 workshop, CPUC staff and representatives from investor-owned utilities (IOUs), tribes and other stakeholder groups unveiled possible ways to improve IOUs’ Climate Adaptation Vulnerability Assessments (CAVAs). A CAVA identifies vulnerabilities and risks to IOU assets, operations and services stemming from the effects of climate change.

“Robust climate adaptation planning in a time of worsening climate impacts is a prudent next step to ensure the safety and reliability” of IOUs, the CPUC said in the “Climate Adaption” section of its website.

“This [workshop] is really critical work to ensure that equity is part of the [climate change reduction] solution,” Audrey Neuman, energy adviser to CPUC Commissioner Darcie Houck, said at the workshop.

In a CAVA, an IOU must describe possible ways to confront vulnerabilities to itself and its infrastructure. These options could be used to determine investments in climate adaptation work, the CPUC said.

The CAVA is part of the CPUC’s 2018 Order Instituting Rulemaking (OIR) 18-04-019 to consider strategies and guidance for climate change adaptation. IOUs must submit a CAVA to the CPUC every four years.

CPUC staff said they are currently working with stakeholders to help create “quantitative equity metrics,” such as a matrix that shows the adaptivity potential of vulnerable communities and infrastructure. Other possible metrics include quantifying a community’s access to resources during an outage; the cost burden of an outage; the impacts of outages on different populations; the impacts of high-frequency outages; and the impacts of long-duration outages.

At the workshop, some stakeholders said too much analysis would be harmful to people who need support now.

“We don’t need to tie together all of the various equity processes … in order to get to some actionable plan that is good enough now,” one stakeholder said. “There are things we know we need to do now, and we don’t have to wait for paralysis by analysis to get to the optimal answer.”

Pacific Gas and Electric representatives said the utility is currently defining which communities need the most attention. Part of the challenge, the representatives said, is that the definition of disadvantaged and vulnerable communities (DVCs) is not specific, which makes it difficult to determine the most vulnerable groups.

“We are looking to target the most vulnerable communities because the DVC definition is quite broad,” said Nathan Bengtsson, PG&E interim director of climate resilience and adaptation. “When we went to [research groups] with the [DVC] definition, almost every group said, ‘Wow, that doesn’t represent a lot of us. You’re leaving out farmworkers, you’re leaving out people with disabilities.”

In 2024, the CPUC required a CAVA to implement a model called the “global warming levels approach,” which seeks to draw a link between regional climate change and specific levels of global warming. This approach is meant to help reduce temperature bias in the CAVA program and “largely separates climate projections from underlying socioeconomic scenario assumptions,” as the climate generally acts uniformly at different global warming levels “regardless of how society gets itself there,” CPUC staff said in OIR 18-04-019.

MISO on Track to Wrap Summer with 122-GW Peak, Addresses Frequent South Advisories

MISO is poised to close the door on summer 2025 with an almost 122-GW peak while issuing several capacity advisories for MISO South.

MISO recorded a 121.6-GW peak on July 29, a few gigawatts more than July 2024’s 118.1-GW peak. Load for the month averaged 92.2 GW, higher than any July in recent years.

Hot weather across the footprint led MISO to its late July peak, which occurred during a maximum generation warning and conservative operations instructions for the entire footprint and while MISO South was under a local transmission emergency. (See MISO Skirts Max Gen Emergency in July Heat.)

Before summer, MISO estimated it would navigate a 122.6-GW peak in its most likely forecast scenario. (See MISO Braces for Hot Summer, Potential 130-GW Peak.) The last time the system hit 122 GW was August 2024.

At an Aug. 28 Reliability Subcommittee meeting, Senior Director of Reliability Coordination John Harmon said the system performed as expected during a “hot, hot, humid and stormy month.”

July’s average daily generation outages were 40 GW, higher than the average 32 GW of the past three years in July. The month’s solar peak at 13.1 GW closed in on a 15.4-GW wind peak. Both occurred in early July.

July’s real-time prices averaged $47/MWh, owing mainly to higher gas prices at $3/MMBtu. In July 2024, $2/MMBtu gas held prices at $30/MWh. Day-ahead market congestion collections for the month more than doubled to $116.59 million from $63.23 million in July 2024.

MISO published more than 50 notifications throughout July for various reasons, including cautioning members about a lack of capacity or transmission capability, warning of severe weather, or updating or canceling instructions and alerts. Many of the notifications were aimed at MISO South.

Majority of Days Come with Capacity Advisories in MISO South

MISO kept up a near-daily cadence of capacity advisories for MISO South — namely Entergy — throughout August. The RTO cited either higher-than-forecast load, squeezed transfer capabilities or forced generation outages as reasons behind the advisories. So far, MISO South has been the focus of 17 capacity advisories in August.

MISO expanded a capacity advisory to the Midwest as well as the South in mid-August as heat enveloped the footprint.

Stakeholders at the Reliability Subcommittee meeting asked MISO what’s behind the more prevalent advisories for the Entergy territory. Harmon said it “made a change to increase the communication about the risk that we see in load pockets” throughout the South. Otherwise, Harmon said systemwide July notifications were from a combination of hotter weather and generation outages.

“They’re almost daily, aren’t they?” Mississippi Public Service Commission consultant Bill Booth said of the advisories directed at Entergy.

WEC Energy Group’s Chris Plante said the declarations have been issued on top of one another, with another announced moments after one expires.

Harmon said MISO’s advisories are only for specific hours of the day that contain elevated risk. He said that’s why the RTO terminates them and reissues them for the following day.

Booth asked if the capacity advisories are part of MISO’s communication response to the Memorial Day weekend load-shedding event in greater New Orleans. (See MISO Says Public Communication Needs Work After NOLA Load Shed.)

Harmon said the string of advisories aren’t a direct result of the New Orleans outage, but that it lines up with “how can MISO communicate risk further in advance.” He said they’re meant to communicate greater risk beyond a normal operating day in MISO South.

“You just see so many of them that after a while you tend to ignore them,” Booth observed.

MISO South’s current Operating Reserve Zone 7 in the circle and the new zone outlined in orange | MISO

The RTO also announced at the Reliability Subcommittee meeting that it will redraw an operating reserve zone in Louisiana and Texas.

MISO South’s Operating Reserve Zone 7 currently includes the West of the Atchafalaya Basin (WOTAB) load pocket. The RTO wants to trim the eastern portion of WOTAB out of the zone to make the Southeast Texas (SETEX) load pocket the more consequential area to the zone.

MISO’s operating reserve zones are different than its local resource zones and are split up so it can ensure ancillary services like regulating and contingency reserves can be dispersed to meet predicted shortages. The RTO currently has eight such zones and can alter them after conducting quarterly studies.

MISO’s Dalton Daughtrey explained that SETEX is a more transfer-limited pocket than WOTAB. He said the RTO is initiating the change so it can more “sufficiently manage reserves in real time.”

Daughtrey explained the narrowed reserve zone aligns with Entergy’s operating guide for the area. He said SETEX contains more “impactful tie lines” and explained there is smaller transport capability in SETEX.

Harmon added the change will make sure reserves are deliverable.

The RTO plans to relegate the eastern portion of WOTAB cut from Zone 7 to Zone 8, which encompasses most of MISO South that isn’t in either Zone 7 or Zone 6 (the Amite South load pocket in southeastern Louisiana).

Eddystone Ordered to Remain Operational for PJM 90 More Days

The U.S. Department of Energy has issued another emergency order keeping Units 3 and 4 of the Eddystone Generating Station in Pennsylvania in operation. 

The dual-fuel, 380-MW subcritical steam boiler-turbine generator units are 55 and 58 years old, and Constellation Energy had scheduled them for retirement May 31. 

But Energy Secretary Chris Wright on May 30 issued an emergency order keeping them in operation to minimize the risk of energy shortfalls in the Mid-Atlantic region. 

That order was to expire the evening of Aug. 28. Wright issued the follow-up order to Constellation Energy and PJM the evening of Aug. 27. 

In an Aug. 28 news release, he said keeping Units 3 and 4 operational has improved energy security in the PJM region. He pointed to the June and July heat waves, when PJM called on the two units to generate electricity. And he said the emergency conditions that led to his first order persist. 

The new order continues until Nov. 26. 

PJM spokesperson Jeff Shields described the order as a “prudent, term-limited step” to keep Eddystone operational. 

“PJM has previously documented its concerns over the growing risk of a supply-and-demand imbalance driven by the confluence of generator retirements and demand growth. Such an imbalance could have serious ramifications for reliability and affordability for consumers,” he wrote in an email. “PJM supports the U.S. Department of Energy’s extension of its order, originally issued May 30 pursuant to Section 202(c) of the Federal Power Act, to defer the retirements of certain generators operating in PJM’s footprint, which spans all or part of 13 states and the District of Columbia.” 

FERC approved a PJM filing to allocate the costs across all RTO load that Constellation incurs keeping Eddystone operational. But that proposal was effective only until Aug. 28. Stakeholders are working toward a longer-term solution for addressing cost allocation for DOE emergency orders through the DOE 202(c) Cost Allocation Senior Task Force. The RTO did not answer questions about whether another Critical Issue Fast Path (CIFP) process is expected to be required for costs under the latest DOE order. (See FERC Approves Cost Allocation for Eddystone Emergency Order.) 

President Donald Trump, Wright and other administration officials have been pushing to halt retirement of gas- and coal-burning power generation facilities as part of their pro-fossil, anti-renewable campaign for American energy dominance, saying a power generation crisis is developing. 

Wright also blocked retirement of the J.H. Campbell coal-burning plant in Michigan in May and issued a follow-up order Aug. 20 extending its potential operation for another 90 days. 

Wright also lifted annual run-hour restrictions on the H.S. Wagner Generating Station Unit 4 in Maryland in July. 

In both cases, Wright cited a shortage of generation capacity.

Constellation said it is prepared to continue operating Eddystone into the fall.

“Constellation is continuing to work with the Department of Energy and PJM in taking emergency measures to meet the need for power at this critical time when America must win the AI race. Constellation will continue to operate Eddystone Units 3 and 4 during the fall,” Constellation said in a statement about the order.

These orders and others issued by Wright are under authority of Section 202(C) of the Federal Power Act, which historically has been an obscure provision but is seeing more frequent use in the second Trump administration. 

The Biden administration issued 11 emergency orders under Section 202(c) in four years, all weather-related. With the Eddystone order, the Trump administration has issued eight orders and two extensions in a little more than four months.

Environmental groups and others have railed against the orders, calling them unnecessary, expensive and causing further pollution.

The DOE order “undermines our energy security and endangers public health and the environment,” Tracy Carluccio, deputy director of the Delaware Riverkeeper Network wrote in a statement.

FERC decided that “the cost of keeping the plant open can be charged to consumers, compounding the harm to our communities who have to now pay to be polluted,” Carluccio added.

“The order should be rescinded and the company should rightly refuse to comply with it,” Carluccio wrote. Pennsylvania Gov. Josh Shapiro (D) “should intervene to stop this egregious order to protect the public and the environment from any further pollution from Eddystone. Anything less makes Pennsylvania and the company complicit with the human health and environmental harms being caused.”
