The sale of Ravenswood Generating Station closed at the end of January.

New York City’s largest fossil fuel-fired power plant has changed hands. The Ravenswood Generating Station, which provides more than 20% of the city’s generation capacity, was sold by its former parent company LS Power to NRG, an energy company headquartered in Texas that owns power plants throughout the country.
It’s not yet clear what this means for “Renewable Ravenswood,” the former owner’s widely-publicized plans to convert the site into a clean energy hub. Prior to the sale, those plans were hanging by a thread. NRG did not respond to detailed questions about whether it will abandon or advance that vision.
“Ravenswood has been an important part of powering New York City for decades, and we recognize how much the facility matters to the surrounding community and the region,” a spokesperson for the company told me in an email. “We’ve begun engaging with community stakeholders and look forward to continuing those conversations in the months ahead. Our leadership team is carefully reviewing all relevant information and is taking a thoughtful, measured approach to any future decisions.”
Ravenswood is made up of four generating units: a natural gas combined cycle plant built in 2004, and three steam generators built in the 1960s that run mostly on natural gas, though sometimes also on oil. The plant is responsible for a sizable chunk of the city’s climate footprint. In 2023, the most recent year for which data is available, the plant emitted nearly 1.3 million metric tons of CO2, or about 8% of the city’s emissions from electricity production.
The Renewable Ravenswood concept was largely celebrated by the surrounding community, which includes two of the largest public housing projects in the country and suffers from disproportionately high rates of chronic respiratory diseases like asthma. The plan, which a local subsidiary of LS Power called Rise Light and Power proposed in 2022, entailed replacing the plant’s three 1960s steam generators with a combination of offshore wind, batteries, and renewable energy delivered from upstate New York via new power lines.
By last year, however, the plan was increasingly looking like a distant dream. Its centerpiece was a proposed offshore wind farm called Attentive Energy, but the project has been on ice since 2024, with little chance of moving forward under the Trump administration. This past November, New York regulators rejected a proposed transmission line that would have connected Ravenswood to a hypothetical future offshore wind development, primarily because there was no longer any such development in progress. Earlier this week, state energy regulators delivered yet another blow to potential offshore wind development when they decided not to solicit offers for new projects to enter the state’s energy market.
Battery development has also had a rocky few years in New York State, which has affected Ravenswood’s transition. Rise Light and Power initially proposed building a 316-megawatt battery project on the site in 2019, but it has yet to break ground. The former CEO, Clint Plummer, previously told me that the company was waiting on New York State regulators to open up their anticipated battery solicitation, which would enable the project to bid into the New York energy market, before building the project. That solicitation opened last July, but it’s unclear whether the company submitted a bid. NRG did not respond to a question about this.
NRG first announced its plans to buy a fleet of natural gas plants — 18 in total — from LS Power in May 2025. Ravenswood was not mentioned in the press release or investor materials, however. “We're acquiring these assets at a significant discount to new build cost, at an attractive valuation, and at the strategically opportune time to be adding high-quality, difficult-to-replicate resources into our portfolio as the sector enters into a period of sustained demand growth,” NRG’s CEO Lawrence Coben told investors at the time.
The purchase was subject to regulatory approval and officially closed a few weeks ago, on January 30. Documents filed with the Securities and Exchange Commission confirm that Ravenswood was part of the deal. Documents filed with the New York Public Service Commission describe the terms in more detail, but they do not mention the proposed transition of the site to a clean energy hub.
Local officials, community groups, and tenant associations were deeply involved in fleshing out the Renewable Ravenswood vision. The Queens Borough President worked with the former owner on a multiyear report called “Reimagine Ravenswood,” released last summer, based on extensive engagement with the community, including public workshops, focus groups, interviews with local leaders, and a community survey. The report is evidence of high hopes the community has for the site’s transition, describing the potential to create jobs, expand public space, and generally increase investment in the neighborhood.
I reached out to many of the local elected officials and community groups that have publicly supported Renewable Ravenswood to ask if they were aware of the sale and whether NRG had made any commitments in regard to the transition plan. Just one responded. State Senator Kristen Gonzalez’s office told me they were aware of the sale, but declined to comment further.

Plus, a look into the future of solar and wind tax credits.
Heatmap AM and Daily will be off tomorrow for the July 4 holiday, but we’ll see you back here on Monday.
We’re staring down the barrel of a holiday weekend here in the United States, so I’ll keep it quick. Two things:
July 4 will mark the formal end of the solar and wind tax credits in the United States. These incentives — which date back in some form to 1978 — were repealed by President Trump’s tax cuts and spending law last year. In order to qualify for the last of these subsidies, solar and wind projects must “commence construction” by Saturday and be ready to generate power by the end of 2027.
Although the policies haven’t yet expired, there’s already chatter about bringing them back. Some Democrats want to revive the incentives should they win back Congress and the White House in two or six years. But 2029 or 2032 will likely look different than the earlier years of this decade, when the Inflation Reduction Act was written and passed: Power prices are higher now, the grid more congested, and the federal budget more constrained. So today, my colleague Emily Pontecorvo previews one of the next big questions in climate policy: Should Democrats try to bring back the solar and wind tax credits?
Her story is great, and one disconnect in particular stuck out to me. Among the climate and clean energy wonks Emily interviewed, “everyone” agreed that “in the near term, the most important thing Congress could do to help clean energy is break down some of the non-cost barriers to development through permitting reform.” Permitting reform, after all, has no fiscal cost and could be achieved during this Congress.
But Democratic lawmakers themselves sound far less sure about its importance. “I don’t think Democrats can engage in a serious way with Republicans on permitting reform,” Representative Jared Huffman, the ranking member on the House Natural Resources Committee, tells her. Read the rest of Emily’s story for more on how lawmakers are thinking about this question, which will only get more important as we get closer to ‘28.

We’ve begun to get Q2 sales data for global automakers — and there’s actually decent news for electric vehicles. Some highlights:
Enjoy your holiday weekend, and remember: We’re now in Q3. Thanks, as always, for reading.
And not for the first time.
The Department of Energy proposed sweeping changes to its rules for updating efficiency standards for household appliances on Thursday. If finalized, they would hamstring future administrations from issuing tighter standards that would save consumers money as higher-performing air conditioners, stoves, washing machines, refrigerators, and the like hit the market.
While the agency portrayed the move as bringing an end to appliance standards writ large, that is not, in fact, what it is doing. The proposal would update the DOE’s so-called “Process Rule,” which governs how the agency develops standards, adding onerous requirements that will make it much more difficult to make any changes at all.
Under the Energy Policy and Conservation Act, the DOE is generally required to review existing standards every six years and assess whether recent technological advances warrant raising the bar for efficiency for any given product category. Updating the standards involves extensive technological and economic analysis, including looking at the cost to manufacturers and payback periods for consumers, as well as several rounds of public comment. After a new standard is issued, products that fail to meet that level of efficiency have to be taken off the market.
The new proposal delivers on the appliance industry’s request that President Trump restore the process he finalized during his first term, which Biden swiftly reversed. The changes include raising the minimum energy savings required to issue a new standard, adding several more steps and requirements to the rulemaking process for new standards, and using industry-developed test procedures to measure the efficiency of new products.
“This obstacle course of restrictions would hinder the department from carrying out its congressional mandate to protect consumers,” Andrew deLaski, executive director of the Appliance Standards Awareness Project, said in a statement. “We have products that keep getting more efficient and we need to embrace these technological advances, not reject them, especially as data centers strain our electric grid.”
Manufacturers welcomed the announcement. “AHAM applauds the Department of Energy for acting swiftly and delivering a proposed Process Rule that reflects years of constructive engagement with manufacturers, consumers, and other stakeholders,” Kelly Mariotti, the Association of Home Appliance Manufacturers’ president and CEO, said in a statement. The Air-Conditioning, Heating, and Refrigeration Institute also told me it “strongly supports DOE’s review” of the rules, although both groups said they were still working through the proposal.
The Energy Department issued a request for information last April seeking comments on potential changes to its procedures for revising energy conservation standards. At the time, the industry’s biggest trade groups urged the agency to “return to the 2020 version of the Process Rule.”
Trump has long been sympathetic to the industry’s ire over ever-tightening standards. He’s complained about dishwashers and heating systems that no longer work and showers that slow to a trickle. Now, Energy Secretary Chris Wright has joined in, grumbling about clothes dryers that run for multiple cycles.
The Process Rule changes threaten the potential to create significant consumer savings, however, according to the Appliance Standards Awareness Project. The group estimates that based on recent technological advances, the DOE’s next round of standard updates could save the average U.S. household $160 per year on their utility bills, and businesses a collective $15 billion in annual operating costs over 20 years. The group also projects that updated standards have the potential to reduce summer peak electricity demand 34 gigawatts by 2040, which would be like taking New York City off the grid. There are climate benefits, too, of course — an estimated reduction of 800 million metric tons of carbon emissions through 2050.
Even if finalized, Trump’s changes to the Process Rule will not be irreversible, and could continue to ping pong back and forth between administrations, “creating the kind of uncertainty and instability that makes it difficult for manufacturers to plan, invest, and innovate with confidence to the benefit of American consumers,” according to Mariotti of AHAM. The industry’s hope is for Congress to amend the underlying Energy Policy and Conservation act to “lock these reforms into statute,” she said. One such effort, the Don’t Mess With My Home Appliances Act introduced by Republican Representative Rick Allen of Georgia, passed the House in February.
The DOE’s proposal follows a memorandum of agreement the agency reached with the Environmental Protection Agency in March to take over as the lead agency running the EnergyStar labeling program, which identifies the most efficient appliances in a given category. The Process Rule changes will not affect EnergyStar, however.
The DOE is accepting public comments on its proposal for 30 days and will hold a public meeting on July 15.
Cities like New York, Philadelphia, and Toronto will see more days like this — but the effects of chronic not-so-extreme heat also build up.
The map of the Eastern United States has turned purple.
That’s the color used by the National Weather Service to distinguish the most severe category of extreme heat — a “rare and long-duration” event “with no overnight relief” — which spread like a bruise on Thursday morning from Chicago to Detroit and across the entire state of Ohio. From there, the purple splits north toward Toronto — where Portugal and Croatia will face each other tonight in a Round of 32 match — and down across the 13 original colonies, from Boston to New York City to Washington, D.C., Richmond, Charlotte, and Atlanta. An estimated 83 million Americans, or about a quarter of the population, are under the most extreme heat warning, with local temperatures cresting 100 degrees Fahrenheit; in many places, humidity will push the heat index up to 15 degrees higher.
That’s killer heat. Although the United States has a higher deployment of air conditioning than Europe, early tallies from the heat wave on the continent in late June found that some 20,000 people died from “heat-exacerbated causes” like heart attacks. In general, in New York City, an estimated 3% of deaths between May and September are due to the heat, a recent city report found — that’s about 500 deaths a year, close to the number of homicides during the city’s year of peak violence in 1990.
“Extreme heat is a chronic stressor that leads to hundreds of deaths in New York City,” Jeff Schlegelmilch, the director of the National Center for Disaster Preparedness at the Columbia Climate School, told me. “I’ve seen models showing the cumulative number of excess deaths over the next several decades could be in the tens of thousands.”
But while heat waves like the one this week bring much-needed attention to the public health crisis, it’s not actually extreme events that are driving those mortality figures. According to the city, about 80% of heat-related deaths in New York occur when temperatures are below 95 degrees Fahrenheit — that is, on hot, but not extremely hot, days. While risk increases with temperature in the way you’d expect, jumping sharply after 90 degrees Fahrenheit is crossed, there are more days in the still-dangerous 82- to 94-degree range on average each summer in New York (74, up from 52 in the 1970s) than extreme heat days like the ones occurring this week (of which there are about 11 per summer).
Schlegelmilch likened the moderate-temperature heat deaths to those during COVID, when it was the frontline workers who were paid hourly, couldn’t take days off, and who lived in more crowded homes who were the hardest hit. “We see those same patterns increasing exposure to heat,” he told me, noting that Latino and Black New Yorkers die from heat stress at rates two to three times higher, respectively, than white New Yorkers.
That said, the majority of people who die from heat-exacerbated causes do so in their homes, which “isn’t necessarily where the totality of the exposure to the heat is,” Schlegelmilch said. In fact, the number of people who die of direct heat stress in New York averages in the single digits per year, by comparison. “If you have to work outdoors, or you have to go back and forth to work and be exposed to the heat, and you go back into a home that is hot, and your body isn’t cooling off at night — this is actually something we’re very worried about tonight and tomorrow night — then the body doesn’t get that break.”
Part of the reason direct heat stress deaths are lower than those caused by chronic exposure is thanks to the agility, urgency, and attention of local governments, which issue heat warnings, promote cooling centers, and take preemptive measures during the worst heat waves — such as Toronto canceling its downtown World Cup watch party this afternoon. In New York this week, kiosks will help direct people to their nearest cooling centers, and local pools will stay open later. Meanwhile, to address more systemic heat impacts on the vulnerable, Mayor Zohran Mamdani has signed an executive order calling for the development and issuance of guidance for protecting outdoor workers and vendors during future heat events.
Because heat-related deaths often take the form of heart attacks, kidney disease, and diabetes, and therefore “don’t fit within the disaster declaration mechanisms” the same way floods or hurricanes do, “we don’t really have good policy to take care of this,” Schlegelmilch added. Particularly in cities with historically colder climates, such as Boston and New York, executive orders like Mamdani’s can be quick fixes, especially when followed by “lengthier and more thoughtful legislation and regulation.” But because the housing stock in such cities is older and, in some cases, even designed to retain heat, saving lives in the long term will require major infrastructure investments, ranging from tree planting to combat the urban heat island effect to expensive retrofitting.
“In the arc of history with disasters, we generally don’t do the things we need to do until it hurts too much,” Schlegelmilch said when I suggested that such a level of investment seems daunting, if not impossible, when spread out over the whole of New York, not to mention the Northeast. “It’s an open question how many people need to die, how many hours of productivity need to be lost, how much strain there is on infrastructure before everybody realizes this is not an abstract problem, that this is happening right now, and that it’s a hell of a lot more expensive to clean up after than to make these investments over the long run.”
An extreme heat wave might not be the primary driver of heat-related mortality in the United States, in other words, but it is certainly an opportunity to push for climate adaptation funding. “It’s not cheap at all,” Schlegelmilch agreed. “But it has to be part of the thinking, because there just isn’t another solution.”
