On solar growth, Hornsea 4, and Rivian deliveries

Current conditions: The first cicada broods have begun to emerge in the Southeast as soil temperatures hit 64 degrees Fahrenheit • Hail and even snow are possible across parts of Spain today • Forecasters have identified a risk zone for tropical storm development in the Atlantic basin, with potential for the first named storm of the year to form by mid-May.
1. Global solar market expected to slow in 2025
The global solar market is expected to grow only 10% in 2025, down from 33% growth in 2024 and 87% growth in 2023, according to a new report by SolarPower Europe. The firm’s “most realistic scenario” accounts for the natural slowdown in development after a boom caused by high energy prices in 2022 and 2023, as well as the “uneven distribution of solar market growth” worldwide, with China accounting for 55% of the market share, lending to the dip in overall solar as it implements reforms this summer in how its renewables are priced and traded.
Speaking at the opening of the Intersolar 2025 conference in Munich on Wednesday, Abigail Ross Hopper, the CEO of the Solar Energy Industries Association, echoed some of the uncertainty expressed in SolarPower Europe’s report. “I don’t think any of us could be in this business if we weren’t optimistic,” she said, adding, “I think we’re going to weather through this storm, but it is going to be a bit rocky for a few years.” SolarPower Europe’s report, meanwhile, anticipates “likely” growth from 2 terawatts of global installed solar capacity at the end of 2024 to 7.1 terawatts of total installed capacity by 2030, which would meet “nearly two-thirds of the 11 terawatt renewable energy target set at COP28.” Under ideal conditions, solar could even quadruple capacity to more than 8 terawatts by the decade’s end. Read the full report here.
2. Orsted cancels 2.4-gigawatt offshore wind project in the UK, citing rising costs
The Danish energy company Orsted announced this week that it is canceling its Hornsea 4 offshore wind project in the UK due to rising supply chain costs and other “adverse macroeconomic developments,” the Wall Street Journal reported Wednesday. Hornsea 4 was expected to become one of the biggest offshore wind farms in the world, with a capacity of 2.4 gigawatts once it was completed. (Equinor’s recently paused Empire Wind I project, south of New York’s Long Island, would have had an 810-megawatt capacity by comparison.)
Orsted warned it would take a hit from the cancellation, with breakaway costs estimated to be between $533 million and $685 million. Nevertheless, “Orsted said the project no longer made economic sense, even with a contract to sell power at government-guaranteed prices for 15 years,” Bloomberg writes. Significantly, the canceled project will also hurt the UK’s efforts to add more renewables to its power grid.
3. ICYMI: Rivian lowered its delivery estimate by as much as 15% due to tariffs
Rivian beat Wall Street’s first quarter estimates, the automaker shared in its earnings letter to investors on Tuesday, but lowered its target for 2025 vehicle deliveries on account of tariffs, CNBC reports. Though the company builds all its electric vehicles in Illinois, “The current global economic landscape presents significant uncertainty, particularly regarding evolving trade regulation, policies, tariffs, and the overall impact these items may have on consumer sentiment and demand,” Rivian said by way of explanation. While it previously estimated it would deliver between 46,000 and 51,000 units in 2025, the revised outlook anticipates 40,000 to 46,000 deliveries. Last year, the company delivered just over 51,500 vehicles, Inside EVs notes.
The company also said it expects to take on “a couple thousand dollars” in additional expenses per vehicle due to the trade policies, though founder and CEO R.J. Scaringe said it’s not planning to increase the $45,000 starting price of the R2 as a result. Despite the continued uncertainty, Rivian said it still expects to achieve a “modest positive gross profit” in 2025.
4. Republicans sneak sale of public lands into reconciliation bill
Republicans on the House Committee on Natural Resources added an eleventh-hour amendment to their portion of the budget package late Wednesday night, calling for the sale of thousands of acres of public lands in Nevada and Utah. Introduced by Representatives Mark Amodei of Nevada and Celeste Maloy of Utah, the provision capitalized on longtime aspirations by Republicans to privatize Bureau of Land Management acreage in the West.
As I wrote on Wednesday, the Republicans’ maneuver, “which came at nearly midnight, left many Democrats and environmental groups deeply frustrated by the lack of transparency,” and critics had little time to comb through the extent of the proposal. While early reviews of the bill estimated the sell-off of about 11,000 acres of land, much of it apparently near cities — in keeping with Republican Senator Mike Lee’s aspirations to use BLM land for suburban sprawl — the Wilderness Society informed me last night that the accounting may end up as high as 500,000 acres or more. That’s consequential not just for public land advocates, but also because “turning over public lands to states — or to private owners — could ease the way for expansive oil and gas development, especially in Utah, where there are ambitions to quadruple exports of fossil fuels from the state’s northeastern corner,” I note in my piece. Moreover, “Reducing BLM land could also limit opportunities for solar, wind, and geothermal development.”
5. Thinning forests to reduce wildfire danger could also mitigate droughts: study
Thinning forests is a favorite idea of Republicans, who’ve rebuked blue states over forestry practices they claim exacerbate the dangers of wildfires. Now, a new study from researchers at the College of Agriculture, Biotechnology & Natural Resources at the University of Nevada, Reno looking at the hydrology of the Sierra Nevadas has found that the practice — along with prescribed fires — could also have potential upsides during drought years, including generating more mountain runoff.
According to the findings published in the journal Water Resources Research, water yields in forests thinned to densities closer to those of a century ago can be increased by 8% to 14% during drought years. That water would be “particularly valuable … to farmers and cities in central California and northern Nevada who rely on Sierra [Nevada] snowpack for much of their water supply,” according to a press release about the research. Significant flooding risks did not appear to increase with the water yields. As earlier researchers have found, however, the results of forest thinning treatments also depend on how, where, and to what extent the treatments are applied. Not all landscapes would necessarily benefit from such regimes. For example, while President Trump blamed the January fires in Los Angeles on poor forest management in California, the blazes were in chaparral, not in forests where thinning could be applied.

University of California, Riverside announced Wednesday that it is launching the nation’s only hydrogen-powered carshare program in a partnership with city and state agencies. Participants can rent Toyota Mirai sedans through a smartphone app and pay hourly rates competitive with Uber and Lyft fees.

The gains set up Democrats to potentially flip the utility commission in 2028.
The blue wave has officially reached the Arizona down ballot. Though two Democratic wins in the Arizona Corporation Commissioner race might not drum up the same national coverage as, say, flipping a Senate seat in South Carolina, the election of Clara Pratte and Jonathon Hill to the five-seat commission could have major energy implications in a state that already saw renewables champions take over the state’s largest utility earlier this year. (With close margins in slow-to-count Arizona, the ACC race wasn’t officially called until Thursday evening, when both Republicans conceded.)
Arizona is one of 10 states that elects its utility commissioners, with the ACC regulating private water, gas, and electric companies in the state. That includes overseeing Arizona Public Service and Tucson Electric Power, where bills have increased 52% and 10%, respectively, over the past five years, per Heatmap’s data. (The publicly owned Salt River Project, which serves much of the Phoenix area, operates largely without ACC oversight.)
The ACC has been wholly in Republican hands since 2024; during that time, the body repealed Arizona’s Electric Efficiency Standards, which had incentivized utilities to pursue energy efficiency programs, as well as the state’s Renewable Energy Standard and Tariff, which supported the build-out of solar and wind power. “They were a rubber stamp for all our utilities and refused to even consider anything in support of protecting our climate,” Arizona State Representative Brian Garcia, who was reelected on Tuesday, said during a press call with Lead Locally this week. “At one instant, one of the commissioners told someone who got sick from the heat — who turned off their power and their AC — ‘Well, that’s on them.’ And I think our state and our communities have had enough of that.”
Though the ACC remains under Republican control despite the two Democratic additions, it puts full control within a one-seat striking distance for progressives when the other three seats are up in 2028 — a much easier fight to win, and potentially a huge one, given that the party hasn’t controlled the ACC since 1997.
Of particular concern in 2026, though, was the development of data centers. Ralph Heap, a Republican in the race who made the League of Conservation Voters’ 12-person “worst of the worst” list out of all 6,342 seats up for grabs nationwide on Tuesday, previously told the Arizona Capitol Times he supports the data center build-out in the name of American AI dominance. Incumbent Republican Kevin Thompson, meanwhile, has argued that the commission “has done its job of shielding ratepayers from costs associated with servicing data centers and other large load users.”
Voters evidently disagreed, backing Hill and Pratte, who say they support a data center moratorium. “The Corporation Commission might not be able to implement a pause, but I think they can certainly be a clearinghouse for information,” Hill told Yellow Sheet Report, an Arizona political tipsheet, acknowledging the relatively limited role the ACC actually has in regulating data centers beyond demanding transparency of utilities’ energy service agreements.
There are other concerns, too. Climate organizers zeroed in on the ACC race because of its influence over the solar buildout in the nation’s sunniest state, where nevertheless six of the state’s 15 counties have a restrictive ordinance against the resource, Heatmap Pro data shows. Commissioner-elect Pratte, a member of the Navajo Nation and the first Indigenous person elected to statewide office in Arizona, is also the co-founder of Navajo Power, a clean-energy company that helps tribal nations develop solar energy and storage projects.
Arizona Public Service and Tucson Electric Power also both have pending rate increase requests under review by the ACC; a 14% rate increase for residential customers and a 45% or more increase for data centers in the case of APS, and a 10% increase for residential customers in the case of TEP. (The APS’ rate case will likely be decided in December, before Pratte and Hill take their seats.)
Additionally, State Senator Lauren Kuby has introduced a bill to change the name of the ACC to the Arizona Public Utility Commission, a move intended to highlight to voters “its significance to their daily lives,” as she told the Arizona Capitol Times earlier this year. Sure enough, John Qua, the campaign director at Lead Locally, and Caroline Spears, the executive director of Climate Cabinet, previously told my colleague Matthew Zeitlin that part of the trouble with supporting progressive candidates in the ACC race was communicating to Arizona voters that, like the race for governor, it is a partisan election.
But given how things turned out Tuesday nationwide — a referendum on cost-of-living and, perhaps, data centers — it seems they needn’t have worried. Arizonans worked out exactly who to blame.
Electricity companies look like one of the biggest losers of the 2026 midterms.

I’m still wrapping my head around the size and scale of the Democratic victory on Tuesday. I suspect Wall Street is, too. Yesterday, the S&P 500 gained about 1.6% as investors saw an upside in the Democratic blow-out. Today, they lost their nerve: The S&P fell almost 4.4%, and the tech-focused Nasdaq slid by more than 5%. That AI-loaded index is now down more than 10% from its all-time high in October, which means it’s technically entered a “correction.” (If it drops by 20%, it’ll be in a bear market.)
Amid the market carnage, utilities have held out alright. The Vanguard utilities index fell by less than one percent today, and two of the country’s biggest vertically integrated electricity monopolies — Duke and Southern Company — actually gained ground. Other power companies — including Xcel Energy, which serves the Midwest and Dominion Energy in the Southeast — did okay as well.
I find that surprising, because utilities strike me as one of the biggest losers of Tuesday’s election.
That’s partly because utilities showed up in surprisingly specific ways in candidate policy proposals this cycle. Last night, I wrote about how Senate Democratic candidates took a fairly moderate tack on climate and energy policy this year. What I didn’t mention is that Adam Hamilton, Kansas’ newly elected Democratic senator, called out utilities specifically in his proposal for major new transmission. One of his four big energy policy proposals is as follows:
Require competitive bidding processes for transmission projects instead of handing utility companies lucrative contracts at taxpayer expense. When a nearly half-billion-dollar transmission project is handed to a single utility with no competitive bidding, Kansas ratepayers can end up paying far more than they should. Competitive bidding has been shown to cut these costs by twenty to thirty percent. Politicians on both sides of the aisle should speak out against harmful policies that avoid competitive bidding, like the $493 million project that was handed to Evergy.
I mean, sounds great to me, but transmission policy does not normally rank among Democrats’ biggest applause lines. Hamilton’s other energy ideas are far more conventional, including ending Trump’s tariffs, his war on domestic energy projects, and restoring the clean energy tax credits.
Hamilton wasn’t alone in targeting utilities. David Pomerantz, who leads the watchdogging Energy and Policy Institute, has a great blog post today looking at utility politics in the 2026 election. He argues that we’re about to see utilities endure a much tougher oversight regime than they’ve faced in decades.
Why? There was much more attention on public utility regulators in this election than there have been in previous ones, he argues. Historically, public utility commission appointments have been sleepy affairs. But “incoming new governors Amy Acton (Ohio), Jocelyn Benson (Michigan), David Crowley (Wisconsin), Aaron Ford (Nevada), and Hannah Pingree (Maine) all campaigned overtly on a promise to appoint commissioners who would put ratepayers first,” he writes. In a few of those gubernatorial races, the losing Republican candidate had also promised to fire or replace the existing utility commissioners.
It goes beyond just oversight. The incoming governors in Pennsylvania, Iowa, and Maine have all vowed to reform or lower utility profits. Democrats won a majority on Georgia’s public utility commission — and flipped two seats in Arizona’s five-person board — promising to look closely at the utility profit structure, too.
In one state, voters even directly intervened to limit utility action. Michigan’s Proposition 2, which bars regulated utilities from making campaign contributions, passed overwhelmingly with more than 80% of the vote (although it now faces a legal challenge). And more than 100 politicians, including the winning Benson, pledged not to take utility campaign contributions.
Anyway, it’s an interesting post. You might remember I spoke to David last week for Shift Key about how the bipartisan permitting legislation would weaken monopoly utilities. As my colleagues Jael Holzman and Emily Pontecorvo wrote yesterday, Democrats and Republicans are now negotiating a top-down amendment to that permitting package. We’ll soon learn if the new version — which could come out any time in the next two weeks — preserves the same tough-on-utilities provisions that Dave praised.
When it comes to energy and data centers, everyone loves Texas. Its pro-business political consensus, unusually deregulated electricity market, wide-open plains, sunny skies, and large natural gas and oil deposits have attracted data center developers, renewables developers, liquefied natural gas export terminals, and battery storage entrepreneurs alike.
But this all happened under decades of unified Republican control of Texas’ government. That’s ending on January 19, when Gina Hinojosa is sworn in as governor alongside every other holder of statewide elected office who won this year. In Austin, they will join a Democratic majority Texas House of Representatives, which has been under Republican control since 2003.
Immediately following the election, stocks linked to data center development in Texas swooned — Elon Musk’s SpaceX is down 12.5% since Tuesday, data center developer CoreWeave is down almost 19%, Oracle is down 9%, Texas-based independent power producer Vistra is down 19%. Sterling Infrastructure, a civil construction company headquartered outside Houston, has seen its shares fall 32%.
On the campaign trail, Hinojosa called for a moratorium on data centers until the legislature could pass legislation putting guardrails around development, including protecting residential ratepayers from electricity price hikes and giving local communities more leeway to restrict and condition development. Two weeks before election day, she released a video criticizing Governor Greg Abbott’s “Batch Zero” review process — which had been broadly characterized as a “pause” when it was announced over the summer — for allowing new permits, and she said that she would issue a “ban” on all data center approvals until new laws could be passed.
When Abbott introduced his pause over the summer, Texas’s electricity market ERCOT had 474 gigawatts of data center interconnection requests in its queue (almost all from data centers), a figure he said was around five times the electricity market’s peak demand. That review is due to end next month, shortly before Hinojosa is due to take office, leaving little time for new projects to get approved before the moratorium goes into effect.
Some observers and investors took a sanguine view of Hinojosa’s data center policies. Gavin Baker, a longtime investor in SpaceX, said on X that Hinojosa’s policies “sound reasonable” and pointed to an interview she gave saying that the moratorium would be on new permits and would not affect the pipeline of permitted projects.
The data center and energy industry, however, is in wait-and-see mode when it comes to the severity of the moratorium.
“If she was thinking of trying to go after projects that had begun the construction process,” Brandt Vermillion, U.S. research lead at Modo Energy, said, “I think it would change the overall outlook a ton.”
According to Modo Energy analysis, there are some 25 gigawatts worth of projects under construction in Texas, another 4.6 gigawatts permitted, and another 90 gigawatts that are either just announced or have only submitted grid studies. If Hinojosa “is only going after non-permitted projects,” Vermillion added, then anyone thinking about the future path of data center development in Texas should be more concerned about supply chain constraints like obtaining enough chips to power the data centers.
That being said, the Texas legislature’s session doesn’t end until May 2027, meaning that Hinojosa’s pause could last several months before lawmakers put guardrails into law.
“I don’t think we’re going to not build another data center in the state,” Joshua Rhodes, a research scientist at the University of Texas at Austin, told me. “But I think that they’re going to be under quite a bit more scrutiny.”
That being said, analysts are now much more uncertain about the future path of electricity demand in the state. “Texas demand is difficult to project after Gina Hinojosa’s surprise win,” Jefferies analyst Julien Dumoulin-Smith wrote in a note to clients on Thursday.
That means more trouble for developers in Texas, especially for storage projects, which had already been seeing extremely volatile monthly revenue.
“Batteries and energy storage have been counting on demand to go up because they’re having a rough time out there right now in terms of revenues,” Rhodes said. “Demand will have a pretty big impact on supply.”
One thing the battery storage industry, as well as solar and wind developers, can cheer is that Democratic control of the governorship and the state House means that the threat of anti-renewables bills has fallen to essentially zero.
The renewables industry is hoping that data center development does continue in Texas, but that it looks more orderly and grid-connected.
Going forward, Vermillion expects that data center developers will have a harder time getting tax abatements, which means that a “well-capitalized hyperscaler” could potentially still pursue projects.
“Project A that was going to go about development in a certain way of seeking tax abatements and buying a bunch of reciprocating engines and trying to run themselves off grid” is much less likely to be able to go forward in Hinojosa’s Texas, Vermillion told me, especially as she is able to appoint new commissioners to the Texas Public Utility Commission or the Texas Commission on Environmental Quality.
Tim Woodruff, the data center lead at Modo, told me similarly. “In the near term, if you're one of the neo clouds, maybe now you start pushing a little harder on your projects that you have in MISO or in CAISO,” he said.
