The U.S. Senate met through the weekend and overnight June 30 to work on Republicans’ budget reconciliation bill, passing it 51-50 with Vice President JD Vance casting the tiebreaking vote around noon July 1.
The One Big Beautiful Bill Act includes most of the Trump administration’s legislative priorities, such as earlier phaseouts of clean energy tax credits. The Senate took out some of the most heavily criticized aspects, including a tax on the production of solar and wind power that was introduced over the weekend. (See Renewables Supporters Decry Late Change to Trump’s ‘Big Beautiful Bill’.)
President Donald Trump welcomed the Senate vote in a post on Truth Social, saying it will lower taxes, raise wages, secure the country’s borders and lead to a stronger military.
But American Clean Power Association CEO Jason Grumet said in a statement that “the Senate reconciliation package is a step backward for American energy policy. The intentional effort to undermine the fastest-growing sources of electric power will lead to increased energy bills, decreased grid reliability and the loss of hundreds of thousands of jobs.”
Grumet noted, however, that it could have been worse. The 12-month phaseout of the tax incentives is aggressive, but the final bill did not include the production tax.
“We appreciate the members of Congress who worked to get this legislation to a better place,” Grumet said. “Their efforts reinforce the basic principle that Congress should not bet against progress in any part of our economy.”
The House of Representatives is expected to quickly take up the Senate version of the bill, having already passed another version with different language on energy tax credits. The House Rules Committee met hours after the Senate passed the bill, clearing the way for it to reach the floor and possibly meet Trump’s personal deadline of getting the bill fully passed by July 4.
ClearPath Action, a conservative group that supports addressing climate change, argued that the bill keeps in place enough tools for industry to move forward on the next generation of clean energy technologies.
“The private sector needs all tools available, including tax credits and faster permitting, to meet the goals of increasing reliable electricity and lowering costs in an era of rising demand,” ClearPath CEO Jeremy Harrell said in a statement. “The reconciliation process started with calls from some to fully repeal all energy tax incentives, which would have devastated the ability to build new clean energy. Senate Republicans and House allies rejected that approach and preserved some financial tools to accelerate American innovation and invest in American manufacturing. We encourage House Republicans to swiftly pass this bill with the key energy provisions included.”
The Senate bill keeps incentives for advanced nuclear, geothermal, hydropower and storage through 2032, while wind and solar credits would be phased out in 2027. It preserves the transferability provisions for the life of each energy credit and retains the 45X advanced manufacturing incentive to support domestic production of critical minerals and certain energy components. It also provides new financing authority for the Department of Energy’s Loan Programs Office to support nuclear, geothermal and energy supply chains.
The Natural Resources Defense Council said the bill cuts tax credits for the fastest-growing source of new generation and is expected to lead to higher power bills around the country.
“With spiking power demand and rising bills, we need more clean, affordable American energy, but Senate Republicans just voted to kill jobs and deliver the largest utility bill increase in U.S. history,” NRDC CEO Manish Bapna said in a statement. “This measure props up the dirty and expensive technologies of the past while strangling the clean energy investments that are creating millions of jobs across the country. At a time when we need new energy more than ever, Republicans are punishing the plentiful wind and solar power that can be quickly added to the grid.”
Bowing to stakeholder requests, IESO officials said they will implement a revised method for breaking capacity auction ties in time for the 2025 contest in November.
A tie-break occurs when two or more participants offer the same price for the last available quantity of capacity in a zone.
Under current rules, the ISO uses time stamps to select the bid submitted first, a method stakeholders have complained about for years.
IESO’s Laura Zubyck, capacity auction supervisor, said in a June 26 webinar that the ISO agreed to accelerate development of a new tie-break procedure in response to stakeholders’ feedback that changing the rules for 2025 was a “top priority.”
Revised Methodology
The new rules will create a multi-step process that IESO said will be more equitable.
In the first step, the ISO will divide the remaining available capacity by the number of offers involved in the tie to determine an equal share of capacity per offer, rounded down to one-tenth of a megawatt.
For example, if there is 40 MW remaining to be allocated and three offers totaling 70 MW, the equal share is 40 MW divided by 3, or 13.3 MW.
| IESO
Step 1: Resource D, which offered 5 MW, is allocated the full 5 MW because it is less than 13.3 MW. Resource A, which offered 25 MW, and Resource F, which offered 40 MW, each are awarded 13.3 MW, leaving 8.4 MW unallocated.
| IESO
Step 2: The remaining tied partial offers are awarded proportional shares of the capacity remaining after Step 1. Resource A, which had 11.7 MW remaining in its offer after Step 1, is awarded 2.559 MW (rounded to 2.5 MW) and Resource F, which had 26.7 MW remaining, is awarded 5.84 MW (rounded to 5.8 MW). That leaves 0.1 MW to be allocated in Step 3.
| IESO
Step 3: Offers are ranked by time stamp. Resource A, which filed earlier, is awarded the final 0.1 MW.
Allotments of Less than 1 MW
One wrinkle: ISO officials said the tie-break process could result in a total capacity allotment of less than 1 MW for a resource, which is not permitted by market rules.
In such a scenario, the resource that would be awarded an obligation of less than 1 MW will be eliminated, and the tie-break process will be repeated starting with Step 1.
For example, if four offers shared the same price for the final 3.9 MW and one would have been allocated only 0.9 MW, it would be eliminated, resulting in three equal allocations of 1.3 MW.
Multiple Constraints
ISO officials also discussed a situation in which multiple constraints are involved in a tie-break — for example an intertie limit and a zonal limit — with the available capacity of one limit lower than the other.
The tie-break for the lower limit would be resolved first using the tie-break steps. The remaining capacity would be allotted to the remaining tied offers associated with the higher limit.
Next Steps
IESO asked stakeholders to provide feedback on the proposed rules by July 10. IESO’s Technical Panel will begin considering the changes in July with a vote to post scheduled for September and board approval anticipated in October. The Nov. 26-27 auction will seek capacity for the periods beginning May 1 and Nov. 1, 2026, with results posted Dec. 4.
The ISO board also is expected to vote in August on rule changes to reduce unfulfilled capacity commitments by making it easier for participants to transfer their obligations and harder to buy them out. (See IESO Seeks to Shore up Capacity Market.)
NEW YORK CITY — Stakeholders discussed uncomfortable economic possibilities at NYISO’s 2025 Spring Economic Conference. The Trump administration’s unpredictable policies on import tariffs, diplomacy and immigration are creating difficulties for businesses.
“We are calling that the economy will slow very significantly, running on the precipice of recession,” said Adam Kamins, senior director at Moody’s Analytics.
This was the first time in six years that NYISO and its stakeholders convened the annual Spring Economic Conference at Consolidated Edison. The mood leading into the presentation was congenial and relieved. The intense heat wave that gripped New York like a fever had broken the night before.
Kamins said the Trump administration’s “tariff roller coaster” had created an unstable situation for global trade. He displayed a timeline of the tariffs, showing the erratic spikes, plateaus, dips and valleys that have affected imports since February.
“It’s whiplash for importers and exporters,” Kamins said. “If you narrow it to the ‘Liberation Day’ tariffs in April, you have these very aggressive 10% baseline tariffs, plus these aggressive reciprocal tariffs … . It’s honestly pretty haphazard.”
Kamins said the administration’s attempt at reciprocal tariffs didn’t make sense. Typically, a government would set these based on another nation’s goods equal to the rate taxed abroad. Instead, Trump’s import duty rates were based on trade deficits. This led to poor nations that cannot afford U.S. goods, like Lesotho, receiving high tariffs on raw materials exports.
“We aren’t exporting anything there,” Kamins said. “They aren’t placing a tariff on us because it wouldn’t matter. Nothing is going there anyway.”
A stakeholder said that even if you supported tariffs, the way they were implemented created a “chilling effect” on investment decisions. Kamins replied that the stakeholder had intuited one of his next slides.
“If firms are thinking about investing or hiring, they need to know the rules of the game,” Kamins said. He said the roller coaster effect limited any potential upside of tariffs by making it difficult to onshore manufacturing, something the Trump administration has said it wanted to do.
Kamins then showed several economic indicators that captured some of what he saw as the fallout of the Trump administration. Container ships were arriving at port empty at Long Beach, Calif., the largest shipping harbor in the U.S. Hiring and job switching have slowed. GDP growth has slowed. Investment plans for the next year have declined sharply. While the overall economy isn’t showing signs of crashing yet, things aren’t headed in the right direction.
While overall workforce growth was flat, Kamins said, the decline of immigrant participation has disproportionately impacted specific industries, like construction, generating headwinds against growth. New York is more dependent on immigrants than other states for labor and population growth, Kamins explained.
New York’s Outlook
Kamins projected that New York generally would follow national trends with some specific exceptions. Compared to nearby states and peer large states, New York’s economy was doing well. Its metro areas were growing in terms of payroll, primarily buoyed by growth in New York City and the health care sector.
“New York is the best-performing state in the region as of last fall and was No. 5 nationally at the time,” Kamins said. “The only other semi-large state that was outperforming New York was South Carolina.”
Metro-area indicators showed most of the growth in the state was concentrated in New York City, with some pockets of growth in Albany and Syracuse.
“When we talk about Syracuse, the most important factor in the outlook is the semiconductor industry and the Micron chip fab [fabricator],” Kamins said. “Construction firms are ramping up hiring in anticipation of that.”
Albany’s strong growth was due to the state government and the performance of local universities.
New York City will be unusually affected by Trump administration policies, Kamins predicted. He referenced sharp declines in Canadian cross-border traffic. European tourism also is down. While tourism has recovered since the pandemic, these factors could cause headaches in the near future.
“New York City relies heavily on international tourism, far more than the rest of the country,” he said.
A stakeholder based in the North Country concurred, noting that Canadians no longer were coming to shop. Kamins noted that immigration restrictions, closed borders and Immigration and Customs Enforcement activity made the U.S. a far less attractive option for tourism or international studies.
New York statewide also suffered from a profound lack of housing inventory, Kamins said, which creates inflationary pressure.
“Price growth for single-family homes is well above the national average,” Kamins said. “This is primarily owed to the supply side of the market. Supply shortages are present pretty much everywhere in the state, but they are most acute in Rochester.”
He said the amount of supply for housing could be measured in “weeks” in certain parts of the state. Homes just don’t stay on the market. While New York City isn’t affected by single-family home prices generally, there also was a supply shortage creating rent inflation.
The presentation closed on an optimistic note: The state still is seeing billions of dollars in investment in semiconductor manufacturing upstate. Micron and Wolfspeed remain committed to developing microchip fabricators, despite delays and financial difficulties.
The Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency (CISA) joined the FBI, National Security Agency and the Department of Defense Cyber Crime Center to “strongly urge” that U.S. critical infrastructure organizations keep watch for attacks on their electronic networks from Iran-affiliated groups.
The agency’s June 30 warning came after several weeks of conflict between Iran and the U.S. and Israel, starting with missile attacks that, Iran’s government said, killed more than 900 people and damaged the country’s nuclear program. (The extent of harm to the nuclear program is in dispute.) Subsequent retaliatory strikes by Iran killed 28 people in Israel, according to the Times of Israel.
Iran also fired more than a dozen missiles at a U.S. military base in Qatar. All but one of the missiles were destroyed before reaching Qatar; the last hit an uninhabited area and caused minimal damage.
CISA and the other agencies said in their press release that they had “not seen indications of a coordinated campaign of malicious cyber activity in the U.S. that can be attributed to Iran.” However, an accompanying fact sheet cited “the current geopolitical environment” as cause for concern “despite a declared ceasefire and ongoing negotiations towards a permanent solution.”
“Over the past several months, Iranian-aligned hacktivists have increasingly conducted website defacements and leaks of sensitive information exfiltrated from victims,” the agencies said. “These hacktivists are likely to significantly increase distributed denial of service (DDoS) campaigns against U.S. and Israeli websites due to recent events.”
Cybersecurity firm CloudSek determined that in the week after Israel’s first strike, more than 35 pro-Iranian cybercriminal groups launched coordinated attacks against Israeli infrastructure. Most of these attacks targeted government agencies, but victims also included energy infrastructure and electric vehicle fleet management software.
Campaigns by Iran-backed actors occurred in late 2023 and early 2024 during Israel’s military campaign in Gaza, the agencies said, with actions against targets worldwide including “dozens of U.S. victims in the water and wastewater, energy, food and beverage manufacturing, and healthcare and public health sectors.” Groups sponsored by Iran also stole and published secret data, primarily from Israeli companies but with one instance involving a U.S.-based internet TV company.
Recommended mitigations to “harden … cyber defenses against malicious actors” include identifying and disconnecting ICS and operational technology assets from the public internet and implementing multi-factor authentication for accessing OT networks from other networks. Agencies also reminded entities to make sure passwords are strong and unique, and to review and update their incident response and business continuity plans.
Cybersecurity firm Dragos noted that Iran continued to pose an active cybersecurity threat in its 2024 Year In Review report, released in February. The report included a newly identified threat group, Bauxite, that “shares substantial technical overlaps … with the pro-Iranian hacktivist persona CyberAv3ngers,” and has reached Stage 2 of SANS Institute’s ICS kill chain, meaning the capability to “meaningfully attack” a target’s industrial control systems. (See Dragos: Attacks on ICS Increased in 2024.)
Leaders from the Electricity Information Sharing and Analysis Center also listed Iran among the top cyber threats to the U.S. grid at the most recent meeting of NERC’s Board of Trustees in May. (See E-ISAC Reports on Cyber, Physical Threats.)
CISA’s warning comes as the agency lacks a permanent director following the departure of Jen Easterly before President Donald Trump’s inauguration. Trump nominated Sean Plankey, former head of cyber policy at the National Security Council, to replace her. However, the Senate Committee on Homeland Security and Governmental Affairs has not yet voted to recommend Plankey to the full Senate and his nomination faces a hold from Sen. Ron Wyden (D-Ore.). Wyden is demanding that CISA publicly release a 2022 report on U.S. telecommunications security to lift the hold.
CISA currently is led by Deputy Director Madhu Gottumukkala, who joined the agency in May from South Dakota’s Bureau of Information and Technology, where he served as chief information officer.
Senators working through the weekend on the One Big Beautiful Bill Act — Republicans’ budget reconciliation bill — delivered renewable energy supporters an unexpected and unpleasant surprise in the form of proposed taxes that likely would stymie completion of projects already in the works.
While the electricity industry expected cuts to energy tax credits, changes to the bill released over the June 28-29 weekend just before it went to the floor added a new tax on energy projects that rely on foreign components.
“With no warning, the Senate has proposed new language that would increase taxes on domestic energy production,” American Clean Power Association CEO Jason Grumet said in a statement. “In what can only be described as ‘midnight dumping,’ the Senate has proposed a punitive tax hike targeting the fastest-growing sectors of our energy industry. It is astounding that the Senate would intentionally raise prices on consumers rather than encouraging economic growth and addressing the affordability crisis facing American households.”
The new taxes would strand hundreds of billions of dollars in investment, threaten energy security and undermine domestic manufacturing, Grumet added.
While changes to energy tax credits were an inevitable part of the legislation, American Council on Renewable Energy CEO Ray Long said, the industry had tried to come to reasonable accommodation that would allow current projects to be completed.
“To be clear, the Senate language effectively takes both wind and solar electric supply off the table, at a time when there is $300 billion of investments underway, and this generation is among the only source of electricity that will help to reduce costs and keep the lights on through the early 2030s,” Long said in a statement. “Along with battery storage and natural gas, wind and solar are the only sources of electricity that can be built in time to meet our increasing thirst for more electricity. Taking these off the table not only increases costs and ensures supply shortages, it also ensures thousands of layoffs and factory closures.”
The U.S. Chamber of Commerce generally supports the bill, but even its chief policy officer, Neil Bradley, posted on X that “taxing energy production is never good policy” and urged Congress to remove the tax from the final bill to avoid higher power prices.
An amendment from Sens. Joni Ernst (R-Iowa), Chuck Grassley (R-Iowa) and Lisa Murkowski (R-Alaska) would moderate some of the language around energy tax credits while still phasing them out for any project that starts construction after 2027.
“This amendment would provide a more workable transition for energy businesses while protecting energy sector jobs and projects currently in the pipeline,” Lisa Jacobson, president of the Business Council for Sustainable Energy, said in a statement. “Clear, predictable and long-term tax policy is essential for market confidence that will get projects deployed quickly and urgently as America faces skyrocketing energy demand. Companies plan with these tax incentives in mind and rely upon them for capital allocation, planning and project commitments — all of which will be jeopardized by abrupt cut offs or additional restrictions.”
Local line congestion is the primary cause of renewable curtailment in California — and the amount is increasing each year, CAISO said during its second-quarter Market Performance and Planning Forum on June 26.
About 80% of curtailment is due to local line congestion in CAISO’s region, rather than oversupply, which sometimes is thought of as the reason why renewable generation is reduced — or curtailed.
“The extent of congestion is widespread, going from major and regional conditions to more local conditions,” CAISO staff said at the forum.
The two primary types of curtailment for solar and wind resources are “Economic – Local,” which is the market dispatch of generators with economic bids to mitigate local congestion, and “Economic – System,” which is the market dispatch of generators with economic bids to mitigate systemwide oversupply.
On May 14, about 27,000 MW of wind and solar was curtailed for “Economic – Local” reasons and about 4,000 MW for “Economic – System” reasons, CAISO staff said. Overall, about 94% of renewable curtailment is for solar resources, and this practice is not unique to specific locations in CAISO’s region, staff said.
In recent years, solar oversupply has been reduced because more solar farms have been built with battery storage facilities nearby — a development approach that allows batteries to more easily charge during hours when solar production is plentiful, CAISO staff said. In general, battery storage resources are helping to flatten the net load in the region, meaning fewer conventional generation resources, such as gas or hydropower, need to be used to meet demand, staff added.
During the forum, ISO staff noted the region’s load has been fully met with renewable resources during intervals on 40 days so far in 2025. Renewables serve load mostly during midday hours when batteries are charging, solar production is high and demand is low.
At the forum, CAISO also reviewed battery performance on March 4 and 5. On March 5, the battery fleet was significantly less charged than normal: 13,800 MWh compared to 35,000 MWh on March 4, requiring gas generation and imports to increase significantly to make up for the lack of battery storage energy available to meet demand, staff said. Battery storage energy was low on March 4 due to higher energy prices during the middle of the day, which minimized how much solar power the batteries soaked up, staff said.
CAISO staff also noted that, during winter months, California’s morning peak is becoming as high as the evening peak. The ISO is studying how the grid can rely on storage resources to meet morning and evening peaks, staff said.
CAISO said certain solar generation forecasting errors increased in 2025 compared with previous years, in part due to growth in solar capacity.
CAISO staff also reviewed the results of a recent change to how battery resources are managed on the grid. The results specifically looked at how batteries performed now that the ISO is accounting for a battery’s state of charge in the upward flexible ramping product program.
Due to this change, the grid operator observed that fewer flexible ramping up (FRU) awards went to storage resources during morning and evening peak times. However, the average resource usage under FRU procurement did not change significantly, said Kun Zhao, CAISO engineer.
“This effort will be a longer-term monitoring project for us, and we’ll definitely give updates,” Zhao said.
The most prolific worry about large load facilities like data centers is how to power them, but the New York Power Authority raised a new concern at the NYISO Budget & Priorities Working Group’s meeting June 24.
When working with a large load customer’s interconnection, NYPA noticed an issue in the ISO tariff that would arise if such a customer ceases operation, creating a “substantial” financial risk to other load-serving entities, the utility’s Tony Abate said.
Because NYISO’s minimum unforced capacity is constant, “any remaining capacity obligation (i.e., the departing customer’s ICAP tag) is spread over all remaining load in the transmission district for the remainder of the capability year,” he said.
Typically, loads that disconnect mid-CY are negligible; but data centers disconnecting would cause a problem, Abate argued. Other LSEs in the district may not have a mechanism to protect themselves from the financial risk associated with the reallocation of UCAP should a major customer leave, he said.
NYISO and NYPA had argued about tariff interpretations until the ISO asked it to come forward with a market project, Abate said.
“We see this as being similar in kind of intent with the … large load interconnection project, which NYISO has prioritized,” Abate said.
The project would entail NYISO investigating the rules that assign or reallocate the UCAP requirement such that if a large load departs a transmission district, the remaining customers are treated equally.
Generation developer JERA Americas also submitted a project proposal to increase transparency in market operations. Specifically, it wants more data regarding system topology, branch characteristics and branch flows. It also wants transmission line ratings and the causes of transmission line outages to be published.
INDIANAPOLIS — The 2025 Mid-America Regulatory Conference tackled themes on meaningful public engagement, nuclear options, bill affordability, and diversity, equity and inclusion (DEI) programs falling out of favor.
Panelists at the June 22-25 conference appeared to agree that focus needs to stay on underserved communities; affordability should be top of mind; and microreactors will make an appearance to handle load growth in the next decade.
Andrew Valainis, an associate at the Regulatory Assistance Project, said people tend to get interested in electricity only when their rates go up.
Valainis said commissions should create public access and engagement plans as part of annual work plans. He also said that “public notice” and “publicity” for meetings are two different things. While a notice is a legal formality, ensuring that at least some of the public is aware of a consequential meeting is a different matter.
Despite more ways than ever for the public to participate in the regulatory process, “people don’t really care,” said Sarah Moskowitz, executive director of the Illinois Citizens Utility Board.
“More often than not, it’s still all of us talking to each other,” Moskowitz said, gesturing to the audience.
She asked regulatory staff to think about why they want public involvement: to “check a box,” generate ideas, get a bead on sentiment, or if they really want public voices to shape the outcome of a proceeding.
“We can’t have this conversation without being honest about what we want from the public,” Moskowitz said. She also said people tend to show up when they are angry. She said if commissions want participation on a “Wednesday night” for an “esoteric, boring” meeting, the public needs to be educated on the regulatory process.
Moskowitz also said it’s “a lot” to expect frontline groups who have been involved previously in commission matters to continue to show up regularly to meetings. She questioned whether commission staff should try to engage the public directly or if public input can be solicited through community-based groups. Either way, she said, regulatory staffs should conduct more community outreach and make webpages easier to navigate with plain language.
Moskowitz said consumer advocate groups “can’t do it all” and said they need some help from the states.
Former MISO COO and President Clair Moeller had a somewhat darker take on public participation. Moeller said he learned throughout his career that there’s a difference between “the public interest and the interested public.”
“People who are educated and have a voice have an outsized influence,” he said, mentioning “well-funded” groups that pay individuals to speak at meetings and submit comments. The regulatory processes seem set up to be confrontational and invite litigation because of their opacity until outcomes are announced. “That’s something I’ve noticed,” he said.
Moeller urged industry players to speak in plain language and not use technical terms. However, he said, “the fact that a lot of these cases end up in litigation” cannot be ignored and has a chilling effect on openness. He recalled he once gave a presentation to answer questions, and the PowerPoint presentation showed up as an exhibit in a state rate case before he could make the drive home.
He urged the industry to create an environment where “it’s safe to answer the question.”
During a “fireside chat,” FERC Commissioner Lindsay See and Indiana Utility Regulatory Commissioner Sarah Freeman both said they have noticed an uptick in legal challenges to commission orders in recent years.
Freeman said she hoped the increased activity is a result of a more informed public. “That matters so much for the outcomes we deliver,” she said.
See said that while clerking for Judge Thomas B. Griffith, of the D.C. Circuit Court of Appeals, she was “struck” by the real-world implications of complex law interpretation. See said she is a huge believer in public service and state service and “genuinely considers” FERC in a partnership with the states.
“I learned a lot about how important the state voice is,” See said of her time as West Virginia Solicitor General.
See said she appreciated the divergence of policy in the midcontinent region and assured attendees that she reads states’ individual comments on FERC filings.
DEI in Actions, not Words
The recent national political backlash to DEI hiring practices and considerations in billing did not deter some panelists from appealing for their continuation.
Michelle Fleurantin, a fellow at the Institute for Policy Integrity think tank at the New York University School of Law, pushed back against the notion that the energy industry exists in a “post-DEI” world. However, she said it’s “scary and challenging” for regulators to conduct targeted outreach for historically disadvantaged ratepayers right now.
Fleurantin said regulators may have to confront a “sticky situation” in which they publicly break with messaging from the federal level and announce intentions to assist burdened communities.
Fleurantin asked regulatory staffs to reflect on the difference between the essential need to hear diverse voices in decision-making and reacting to an “unreasonable chilling effect” from state and federal lawmakers. She said it’s necessary for regulators to consider equity and inclusion in their work to figure out if initiatives “actually work on the ground” and discern whether decisions could risk putting “large swaths” of a population in danger.
“DEI is obviously super politicized, but we need to home in on outcomes,” Fleurantin said.
Fleurantin said continuing to set aside a significant percentage of investment for underserved communities should continue. She said although it’s by now a cliché to recommend people call their elected officials, she advised them to do so to encourage continued funding. However, she allowed that it’s difficult for the public to understand how to become involved in utility decisions. “It’s very opaque; it’s very technical; there’s definitely a high barrier to entry in these spaces.”
Panelists also touched on how DEI works in hiring practices in today’s political climate.
Tim Simon, principal and founder of TAS Strategies and former member of the California Public Utilities Commission, said his firm is advising clients that there is a difference between a federal mandate and state ambitions.
“Once upon a time, they called them ‘states’ rights,’” he said and noted that there’s now a “friction” between the federal government and some states. He noted that Indiana Gov. Mike Braun (R) broadly replaced the DEI efforts in the state with a “merit, excellence and innovation” philosophy.
“I don’t think it’s time to really pull out our bayonets. I think we have more in common,” Simon said. He stressed that “our workforce and our suppliers are an issue of national security” and said skilled workers across the country can fill needs. He said the best candidates can earn jobs while simultaneously satisfying divergent aims from states and the federal government.
“I think we have to get away from the nomenclature and do the work,” he said, adding that regulators have more work to make sure rates are just and reasonable. He said more and more households are being pushed into low-income status, which isn’t sustainable for the utilities’ business model.
“Do we have a diverse pool of candidates every time we have an opening? Yes,” Commonwealth Edison CEO Gil Quiniones said. He said those diverse candidates then are sized up by a diverse hiring committee, with the best candidate selected.
“I would stack up our team against any utility in the country,” he said.
Affordability Concerns
RMI Senior Associate Maria Castillo said research shows U.S. households increasingly are forgoing other expenditures to afford their energy bills.
Oracle Director of Regulatory Affairs Julia Friedman agreed there is an energy affordability crisis. She said when electricity bills rise 30 or 40%, it pushes a lot of customers who never have needed bill assistance into needing help. However, she said utilities’ increases are coinciding with a “stagnation” in customers turning toward assistance programs.
Friedman said according to Oracle’s research, customers say their mortgage or rent payments and utility bills are the household expenses they feel they have the least amount of control over.
“We have to overcome … customers feeling like they have no control over their bills,” Friedman said. She said utilities can provide an online one-stop shop for discounts and time-of-use programs.
Chris Villarreal, an associate fellow at R Street Institute, said a state-funded consumer advocate coupled with state regulators can apply “some amount of pseudo-competitive pressure” on monopoly utilities to keep their rates in check.
Villarreal said customers now have more viable options available for them to supplement their supply, mentioning rooftop and community solar.
“There’s not one place that provides the electricity. Now, there’s one distribution system that delivers the energy,” he said.
Julia Selker, of Grid Strategies’ Working for Advanced Transmission Technologies Coalition, said grid-enhancing technologies can pull more monetary value from the grid and help lower bills.
Selker said if transmission operators were to place a dynamic line rating on a highly congested line, it would pay for itself in a weekend. She said even a “walking” wind speed can cool lines down enough to carry 30% more power.
Selker said at this point, utilities’ hesitancy to deploy grid-enhancing technologies is only “cultural.”
Once Again, Load Forecasts
No industry conference is complete in 2025 without a debate on load growth, and MARC 2025 delivered.
RMI Principal Lauren Shwisberg said load forecasts should be taken “seriously, not literally.”
She said RMI has found that historically, utilities over-forecast their load by about 17%. She said while under-forecasting poses risks to reliability, over-forecasting threatens affordability.
“We’re operating at margin, and we’re doing a pretty darn good job,” MISO Executive Director of Transmission Planning Laura Rauch said. But Rauch said operating without the 25% cushion that existed when she was a “baby engineer” makes grid planning more difficult.
Rauch said the urgency surrounding the need for construction often reminds her of a saying that “the best time to plant a tree was 20 years ago if you want the shade now.”
“The next best time is today,” she said, later adding: “You can’t piecemeal your way to serving a city-size load.”
Even with a co-located generation plan, data center loads largely plan to draw on the system when their own generation is unavailable and inject into the grid when they aren’t fully using their on-site power source, she said. Utilities, data center customers and MISO need to match “desires and incentives with commitments” to weed out speculative announcements.
Google’s Tyler Huebner addressed the possibility that “six to 10 data centers might become two to three.”
“I don’t want to give the idea that we’re just playing around with load forecasts. The reality is that it’s very complicated to build a data center. … It’s not malfeasance, and it’s not [us] trying to be a bad actor in any way,” Huebner said. He said data center developers must consider the most opportune spots to connect, the availability of generation and optimal siting.
MISO Senior Vice President Todd Hillman said the energy industry is learning to be “dynamic and disruptive” with new technology avenues amid load pressure. He noted that about 97% of MISO’s interconnection queue is solar, wind and battery storage. But he also said MISO is lacking about 31 GW in new generation projects that should have been online by now but are stalled.
“Imagine 31 more gigawatts today. The summer is still going to be hot, but it’s going to be a different story in terms of what we can do,” Hillman said. He said the holdup can be traced to five causes: “People, parts, permitting, politics and pricing issues.”
“Our industry represents 5% of the economy, but it’s the first 5% of the economy,” ITC Holdings CEO Linda Apsey said.
Apsey noted that the American Society of Civil Engineers rated U.S. energy infrastructure a “D+,” which isn’t going to cut it for a grid that will see rising demand from data centers and manufacturing onshoring. Apsey said the score is the same as 20 years ago, despite pains since then to refurbish and build out the aging grid.
“Time is of the essence, and reliability and resiliency is of the utmost importance,” she said.
Apsey said the last time the country saw material load growth was in the 1970s when a wider selection of home appliances and home air conditioning took off.
She said utilities don’t have a choice but to accept the economic opportunity that data centers present or risk losing them to other states or regions. “For them, it’s a race. They have to be first to market.”
The Nuclear Option
“I don’t think you can walk into a room and not hear about data center growth,” Constellation Energy Vice President of Strategy and Growth Colleen Wright said.
Wright said there’s a “perfect storm” of conditions that can help get new nuclear built to replace baseload generation.
“I don’t think that window is open forever,” she added.
Timothy Grunloh, principal research scientist at the University of Illinois Urbana-Champaign, said he hopes the university’s plans for a research reactor can show that microreactors “can be built with a predictable schedule; a predictable budget.”
Grunloh is helping to develop a modular microreactor to figure out whether permitting, siting, safety reviews, supply chain or regulatory processes present the biggest barrier to building new nuclear generation. The demonstration reactor will rely on tri-structural isotropic fuel particles, which consist of uranium-based kernels that use graphite as a moderator.
A decade ago, he said he would have characterized the Nuclear Regulatory Commission as a “bogeyman” that tries to “trip up” developers. However, he said his experience working with the NRC is the opposite and said staff are all about, “How do we get you to ‘yes’ safely?”
Grunloh said so far, his team has found that the supply chain presents the biggest challenge.
“Beyond that, all roads go through public perception,” he said. Grunloh said the public’s recent softening toward nuclear energy thus far has been hypothetical. He said that positivity may change once some reactors become reality. Grunloh added that small reactors could be ready in commercial use sometime around 2029.
In a later talk, Gov. Braun said he couldn’t think of anything else “tested to the degree” as nuclear has been to provide future baseload power. He said he thinks U.S. Energy Secretary Chris Wright and the Trump administration should be able to clear regulatory obstacles to scale up new nuclear quickly. In response to an audience question, Braun said he’s open to experimenting with small modular reactors at the state’s military sites.
Braun said he viewed himself as a “conservationist” but in a “practical” way. He said he saw an ongoing spot for coal in Indiana’s energy mix until enough batteries or nuclear generation can be installed.
SPP has secured $150 million in financing and entered the second phase of development for its day-ahead market Markets+, the grid operator announced June 30.
Arkansas-based Simmons Bank provided the loan, which is collateralized by eight Markets+ funders, allowing SPP to begin developing “critical systems, processes and operations required to conduct market trials,” according to the announcement.
“Securing financing for phase two of Markets+ is a pivotal step forward,” Carrie Simpson, vice president of markets at SPP, said in a statement. “It allows SPP to continue developing a more efficient, transparent and reliable energy market for our western stakeholders and their customers.”
With the announcement, SPP has entered the second phase of market development. The grid operator already has started its requirement planning and Markets+ training for stakeholders. Stakeholder onboarding processes, including network and commercial modeling, are scheduled to begin Aug. 1, 2025, while connectivity and data exchange testing is slated for late 2026. SPP plans to launch Markets+ on Oct. 1, 2027, according to a timeline posted on SPP’s website.
According to the June 30 news release, the eight Western entities that have signed the agreement include Arizona Public Service, Bonneville Power Administration, Chelan County Public Utility District (PUD), City of Tacoma, Grant County PUD, Powerex, Salt River Project and Tucson Electric Power. (See SPP Secures Funding to Begin Markets+ Phase 2.)
The agreement requires the entities to provide collateral to SPP’s lender to support the financing the RTO will use to develop Markets+ during the implementation phase. The collateral is equal to the amount of the entities’ Phase 2 obligations.
The recovery of the costs to repay the implementation financing “will be incorporated into the rates charged in the Markets+,” according to a frequently asked questions document posted on SPP’s website.
Agency spokesperson Nick Quinata told RTO Insider that BPA’s commitment for Phase 2 will not exceed $36 million based on the current number of funding parties.
“If additional parties join Phase 2, that would reduce BPA’s share of Phase 2 development costs and, thus, total liability,” Quinata said. “All entities participating in Phase 2 will have these costs recovered through transactional fees once they begin market participation.”
Meanwhile, Grant PUD spokesperson Christine Pratt said the utility acquired a letter of credit for about $4.2 million to contribute to Phase 2. The credit will assist with “the upfront expenses needed for market startup. This includes computer systems — hardware and software — and personnel.”
Grant PUD noted that it did not have to contribute any funds for Phase 2 but was required to provide a letter of credit in case the market failed. Under that scenario, the credit will be called for the amount needed by SPP to recover any costs incurred in standing up the market.
“We’re preparing for Markets+ trading by evaluating our own needs for personnel and equipment,” Pratt said. “Our basic interests or priorities are for the market to succeed. These priorities will likely become more specific as collaboration continues, but for now, a successful market is the goal.”
Chelan PUD spokesperson Rachel Hansen said the utility contributed about $820,000 in collateral.
Chelan now “will focus on preparing for market readiness and has not chosen its go-live target date,” Hansen said.
SPP said in the news release that stakeholders are signing additional Phase 2 funding and participation agreements “based on their entities’ respective sector and role in the market.”
ERCOT 4.0 Shapes Path Forward for the Grid Operator
ERCOT CEO Pablo Vegas has gone public with the grid operator’s internal terminology that is shaping the market’s path forward, defining it for his Board of Directors and stakeholders.
“This represents more than just the branding of current activities that we have underway,” Vegas told the board during its June 23-24 meeting. “It really represents a distinct new phase in the ERCOT market. It also provides a strategic lens to look at the priorities and the initiatives that we’re going to be investing in to make sure that we continue to deliver on our mission, which is getting more complex and more dynamic every year.”
Labeled “ERCOT 4.0,” the construct builds on previous versions of the grid operator’s market and its transitions: 1.0 (original formation in the 1970s), 2.0 (deregulated competitive markets and the zonal market in 1999) and 3.0 (the nodal market in 2010).
“Each of these transitions was driven by a combination of either technology changes, regulatory changes [or] market-driven forces. ERCOT 4.0 reflects this transformation that’s underway right now,” Vegas said.
He said ERCOT 4.0 is defined by the exponential growth in system complexity and the convergence of three major drivers: the rapidly changing resource mix, significant and unpredictable load growth, and technology-driven operational changes, such as artificial intelligence advances and high-frequency data access.
“This is changing how we forecast. This is changing how we operate. This is changing how we plan,” Vegas said. “The convergence of these three things … are the core underpinnings of what ERCOT 4.0 looks like for the next generation of ERCOT. This is a new paradigm.”
ERCOT’s transition from 1.0 to 4.0 | ERCOT
Vegas said the grid operator will have to evolve its planning assumptions “to account for the uncertainty and the variability that we’re seeing across both supply and demand.” He said grid operations will have to become more adaptive and market mechanisms will have to be re-evaluated to ensure “those signals support long-term system reliability as well as short-term market efficiencies.”
“Probably most critically of all, our workforce is going to have to be equipped to lead in a system that is increasingly software-defined, data-rich and constantly changing,” Vegas said, noting the grid operator is investing in professional development and other tools so the team can “operate and lead in this new reality.”
Staff are focused on innovation to transform the organization and maintain operational excellence in a more complex system.
“It’s a huge opportunity to reinforce our leadership in the energy economy here in Texas,” Vegas said.
He closed his comments by tying ERCOT’s 2025 Innovation Summit in May to ERCOT 4.0. The summit drew more than 450 attendees, with more than 400 other people livestreaming the event.
“It was an opportunity to really showcase innovation efforts, not only within ERCOT, but [also] what’s happening in transformations around the world and around the United States, bringing people together to talk about the most complex issues that we’re dealing with, learning from each other, establishing networks of communication that are going to be helpful as we continue to work on solving these problems together.”
Board Approves $1.07B 2-year Budget
The board approved a two-year budget of $485 million for 2026 and $585 million for 2027, totaling $1.07 billion. However, the budget includes a system administrative fee of 61 cents/MWh, down 2 cents from the current fee.
Both changes go into effect in January 2026.
Board Chair Bill Flores | ERCOT
Board Chair Bill Flores, who also chairs the Finance and Audit Committee, acknowledged that the biennial budgets are “substantial increases from where we are today.”
“But as we all recognize,” he said, “because of the mandates promulgated by the legislature in the last two legislative sessions, as well as the increasing complexity and the dynamic nature of this market, as well as the focus on reliability, the cost of running the organization is higher than it was before.”
He said the budget includes “appropriate” funds and staff to address ERCOT’s strategic objectives and comply with the financial corporate standard and associated financial performance measures. The budget also funds the Independent Market Monitor and compliance with Texas Public Utility Regulatory Act and NERC obligations.
Flores said the budget assumes the administration fee can be kept flat for up to six years.
Matt Mereness, senior director of market operations and implementation, said ERCOT has received the final deliveries of vendor code and completed two operating day end-to-end tests of systems and integration. He said the test environment was deployed weeks ahead of its May 5 start date, and a first round of defects was fixed and redeployed later in the month.
After establishing connectivity with market participants and testing submissions, the RTC+B project will begin parallel production trials July 7. Mereness said market trials will focus on frequency control tests in the September-October time frame.
“All the participants will put in reasonable offers that represent [a percentage] of their costs, and we’ll start [dispatching]. That’ll be the real-time co-optimization,” Mereness said. “They’ll have [ancillary service] offers in, and ERCOT will start to print prices and signal where [participants] should go, but no one will go there. Here’s the solution, but don’t follow it.”
The project is set to go live Dec. 5.
Staff Responds to IMM Report
ERCOT staff responded to the IMM’s recent State of the Market report for 2024, saying, “Overall, it’s a very good and well-written report.”
“There are definitely some things we agree with and some other things that we may be in disagreement,” said Keith Collins, vice president of commercial operations.
He said staff are aligned with the IMM’s comments on improvements to ERCOT contingency reserve service (ECRS), which reduced the product’s average price from $76.77/MWh to $9.62/MWh, and the effective load-carrying capability in the grid operator’s Capacity, Demand and Reserve report.
“There are a few recommendations or items that the IMM pointed out that we believe we’ve already addressed,” Collins said.
Responding to the IMM’s recommendation that ECRS include a forecast trigger, he said ERCOT has a three-part trigger for the product. Collins said a trigger that looks forward at the net load ramp addresses that need.
In its report, the IMM continued to recommend that the grid operator reconsider its policies for procuring and deploying ECRS. (See ERCOT ESRs, Solar Production Lessen AS Costs.)
ERCOT also disagreed with the Monitor over non-spinning reserves’ duration. The grid operator wants four hours, while the IMM favors a one-hour duration.
Two Tx Projects Approved
The board approved a pair of Oncor transmission projects in West Texas with combined total costs of $974 million.
The $855 million Delaware Basin Stage 5 project addresses reliability concerns and accommodates “significant and rapid load growth” in the petroleum-rich area. Oncor will build 220 miles of transmission lines in creating an import path to serve load now that the basin’s peak demand is greater than a 5,422-MW threshold. (See “Oncor $855M Project Endorsed,” ERCOT’s TAC Extends Duration of Ancillary Services.)
The $119 million, 138-kV Tredway Switch and 138-kV Expanse-to-Tredway project entails upgrading 29 miles of lines and updating other facilities and infrastructure to address reliability issues. Oncor expects to finish the project in December. (See “TAC Endorses $119M Oncor Project,” ERCOT’s TAC Endorses Congestion Management Plan.)
Both projects were selected by ERCOT’s Regional Planning Group from other alternatives. As Tier 1 projects with costs exceeding $100 million, they require board approval.
With little discussion, the board also approved:
the third phase of the Aggregate Distributed Energy Resource (ADER) pilot project, which enables a new participation model for resources providing ancillary services but that are not in the five-minute real-time energy market. The first two phases limited total registered capacity of all ADERs to 80 MW for energy and 40 MW for non-spin and ECRS; staff proposed increasing the limits to 160 MW and 80 MW, respectively, for Phase 3. (See “TAC Endorses ADER Doc,” ERCOT’s TAC Extends Duration of Ancillary Services.)
a real-time market correction of $81,858 to market participants after a routine software update changed an energy management system setting to its default value, causing a stricter limit on a generic transmission constraint (GTC). That led to the activation of a post-contingency overload on the GTC, affecting dispatch optimization that resulted in a maximum shadow price of $5,251/MWh over March 28-29. The first operating day was corrected within a two-day business deadline, but not the second day. The maximum absolute value impact to counter-parties was $99,580.
Board Loses 2 More Directors
Chair Flores opened the meeting by announcing that the two most recent independent directors, Alex Hernandez and Sig Cornelius, have resigned to pursue “new opportunities” in the ERCOT market. State law requires the 12-person board’s eight independent directors to not have fiduciary duty or assets in the grid operator’s territory.
That leaves the board with three vacancies. Bob Flexon resigned in December 2024.
Flores said the board’s selection committee is working to fill the three vacant seats. He said the goal is to have them in place by the board’s September meeting.
Protocol Changes
The board approved a nodal protocol revision request (NPRR1282) and its associated Nodal Operating Guide revision request (NOGRR277) that provides longer-duration ancillary services and state-of-charge (SOC) parameters in advance of the RTC+B project’s deployment in December.
The NPRR updates duration requirements to 30 minutes for regulation service and responsive reserve service and one hour for ECRS. It also revises reliability unit commitment studies’ requirement to one hour for all ancillary services, excluding fast frequency response. (See ERCOT’s TAC Extends Duration of Ancillary Services.)
ERCOT supported the measure, saying there is a need for a four-hour ancillary service to cover periods when deploying non-spin. Dan Woodfin, vice president of system operations, said staff analysis revealed that when non-spin is deployed, “we’re basically having to cover the gap because of either an extended forecast error or units that trip offline.”
“We can deploy reserves, but then we need to last longer until we can get the next generation committed to cover the gap or until the net load goes down,” he said.
ERCOT is also developing dispatchable reliability reserve service as a four-hour AS product to cover risks.
Jupiter Power’s Caitlin Smith, who chairs the Technical Advisory Committee, said the change conflates “duration” with SOC, “a misapplication of fundamental [energy storage resource] concepts [that] results in a drastic departure from current ERCOT standards regarding duration and state of charge.”
The board agreed with ERCOT’s commitment to revisit the NPRR once RTC+B becomes part of the market.
The directors also endorsed NPRR1229, which creates a process to compensate market participants when a constrained management plan or ERCOT-directed switching instruction trips a generator that otherwise would have remained online. (See ERCOT’s TAC Endorses Congestion Management Plan.)
The consent agenda of unopposed protocol changes at TAC included five additional NPRRs, two NOGRRs, an Other Binding Document (OBDRR), an addition to the Planning Guide (PGRR) and a system change request (SCR) that:
NPRR1226: directs ERCOT to prepare and publish estimated demand response data showing aggregated state-estimated load points selected by the grid operator. Loads selected for the report will be based on periodically updated offline analysis of the frequency and magnitude of reductions observed in historical state estimator load data that are associated with LMPs, ERCOT-wide conservation appeals or other market signals.
NPRR1238 and NOGRR265: introduces a new early curtailment load (ECL) category and establishes a process allowing loads to operate as an ECL so they can be accounted for differently in load-shed tables.
NPRR1267: requires a large-load interconnection status report be published. The report won’t define “large load,” leaving that to NPRR1234 (Interconnection Requirements for Large Loads and Modeling Standards for Loads 25 MW or Greater). Confidential customer information on large loads will be aggregated.
NPRR1271: allows Mexico’s state-owned electric utility, the Federal Electricity Commission (CFE), to opt out of a requirement to designate a user security administrator and receive digital certificates. CFE is registered with ERCOT as a transmission and/or distribution service provider, a load-serving entity and a resource entity.
NOGRR275: aligns the guide with protocol changes to eliminate scheduling center requirements for qualified scheduling entities that are not wide-area network participants.
OBDRR054: creates a process by which transmission and/or distribution service providers will require market participants to successfully test retail transactions before their data universal numbering system is activated in a TDSP’s production system.
PGRR125: adds language to that guide that allows an interconnecting entity or property owner to demonstrate compliance under the Lone Star Infrastructure Protection Act should it have a subsidiary or affiliate that falls under the act’s citizenship or headquarters criteria. The subsidiary must not have direct or remote access to or control of the project, the project’s real property, resource integration and ongoing operations, the market information system, other ERCOT systems or any confidential data from the systems.
SCR830: implements a machine-to-machine client credentials authentication flow using OAuth 2.0, allowing for certain read-only endpoints of the GINR Rest Application Programming Interface to be exposed for authorized use.
