The country’s chief energy regulator issued major updates to the transmission planning process.
On the two ends of the energy transition, public policy is working to encourage more non-carbon-emitting electricity generation (think wind, solar, and batteries) and convert what was once powered by combustion in electric power (think electric cars and heat pumps). But then that leaves the middle.
The solar arrays and wind farms that the federal tax code and many state policies promote and subsidize can’t serve all that new electric demand from cars and heat pumps (not to mention existing demand for electricity) if they can’t connect to the grid. That’s where the Federal Energy Regulatory Commission steps in — not by funding or mandating the construction of new energy transmission infrastructure, but by laying out the rules for planning it.
On Monday, FERC unveiled and approved a rule overhauling regional transmission planning to take into account the ongoing and planned transformation of the electric grid. Since 2010 at least, energy planning and construction has been motivated almost solely by incremental need, i.e. the only things that got built were those deemed necessary to keep the literal lights on. A Department of Energy report released last year showed that overall transmission investment and construction has slowed down since the second half of the 2010s. That’s led to a “queue” of projects waiting to connect that’s around 90% renewables.
All of this is especially distressing as the energy transition will require a vast expansion of our transmission capacity. Increased demand from electrification, new manufacturing, data centers, state policies that mandate the use of renewable energy, federal policies like the Inflation Reduction Act, and corporate policies that mandate the procurement of non-carbon-emitting power is transforming the grid.
While the 1,300-page rule has not yet been released, FERC commissioners and staff described new requirements that regional transmission organizations adopt the long view, extending their planning horizon over a 20-year period and calling for updates every five years. This means grid planners will have to take into account factors making the grid cleaner, including corporate commitments to purchase clean energy, public policy pushing renewables, the retirement of fossil fuel plants, and utilities’ own designs for the future.
But that’s just the planning process. When it comes to actually building — and paying for — new transmission, FERC is requiring regional transmission planners to consult a specific set of economic and reliability benefits like reducing congestion on the grid and resilience against extreme weather and lower costs when selecting projects.
Many would-be transmission projects founder on how to split up costs between the various regions and utilities any new infrastructure will serve. Transmission planners, therefore, often prefer local projects that serve the existing grid and can thus avoid the tricky business of how to split the bill. Within the PJM Interconnection, the country’s largest regional transmission organization, about six times as much local transmission was approved from 2014 to 2022 compared to regional transmission, according to research by Massachusetts Institute of Technology economists.
It’s easy to see why the regional planning process can be contentious and complex. There’s no one set way to do it because there’s not always agreement on who benefits and to what extent from any given project. This has only gotten more true as some states have passed decarbonization or renewable energy mandates as others have resolutely not. Under the new rule, transmission planners will have to come up with a default method for allocating costs associated with new projects as a fallback in cases of disagreement.
Senate Majority Leader Chuck Schumer, who has pushed FERC to make transmission planning easier, claimed victory in a press conference following the announcement. He described the new rule as a “missing piece to the puzzle” of the IRA that could help jumpstart a transmission buildout. That will be especially key in the absence of Congressional action. Though hopes were once at least moderately elevated that Congress would take steps to accelerate the complex permitting process for large-scale energy projects this session, any sense of possibility seems to have disappeared.
“I’ve told Joe Manchin, it's going to be virtually impossible to get something done,” Schumer told reporters, referring to the barnstorming West Virginia senator and chair of the Senate Committee on Energy and Natural Resources, who’ll be retiring in January, when his current term expires.
While FERC cannot wave a magic wand and fund transmission projects or get agencies to speed up environmental reviews, it can focus and direct transmission planners to figure out what kinds of transmission needs to be built and how it will be paid for. In another corner of the executive branch, the DOE recently designated 10 “corridors” where the need for new transmission is particularly acute. Projects in these areas could be eligible for additional financing and bypass certain permitting hurdles.
Environmental groups like the Sierra Club, the Natural Resources Defense Council, and the Environmental Defense Fund, as well as Senate Democrats almost immediately hailed the FERC decision. Ray Long, president of the trade organization the American Council on Renewable Energy, said in a statement that the rule will “enable the delivery of power from cleaner and more affordable electricity generation that will benefit consumers all across America.”
The Commission’s sole Republican member, former Virginia regulator Mark Christie, was not so effusive. He issued a harsh dissent to his colleagues’ decision, likely previewing a judicial challenge from Republican-governed states. While the Commission’s chair, former District of Columbia public service commissioner Willie Phillips, and its other member, NRDC alum Allison Clements, both Democrats, largely spoke about the rule in terms of reliability and reforming the planning process, Christie made it seem like a climate change policy in disguise that would function as a “transfer of wealth” to wind, solar, and transmission developers.
“This is not about reasonable improvements to regional planning,” Christie said. “This rule is a shell game designed to disguise its true agenda that is about the money. It’s a 1,300-page vehicle to socialize the cost of the rule’s sweeping policy agenda.”
Christie also raised the prospect that consumers in states that have not adopted mandates for renewable energy could end up being forced to pay for transmission projects necessary to connect renewables to the grid, turning consumers into “involuntary beneficiaries.” While this may not sound so bad, a key principle of allocating costs for transmission is that whomever benefits — no matter how those benefits are calculated — should pay. If, as Christie argues, there’s disagreement over what counts as a benefit, being an involuntary beneficiary is no good.
While the details of the rule remain to be seen, it did not list any environmental benefit to new transmission as the type of benefit that transmission needed to tally up when considering a project; instead, it said that transmission planners should consider how public and corporate policies are affecting the mix of generation when making their long-term transmission plans.
Commissioner Clements argued in her remarks that this was a narrow perspective on transmission planning, and that “it is not the Commission’s job to try and force the genie that is the energy transition back into the bottle.” States should avoid the temptation to “get drawn into a lose-lose debate over who, precisely, caused the need for each specific system upgrade as the grid’s inadequacy festers,” she added.
Rob Gramlich, the president of Grid Strategies LLC and a leading transmission advocate, added his voice to Clements’, tweeting that the notion that “beneficiaries should get to opt out of paying for infrastructure … is counter to every lesson about how every type of infrastructure has ever been funded.”
While those celebrating no doubt disagree with Christie’s claim about cost, they agreed that the rule would spur the transition to non-carbon-emitting sources of power. Just to meet the likely increase in energy usage from existing policies like the IRA and the Bipartisan Infrastructure Law, the DOE estimates there would need to be at least 64% increase in transmission within regions — precisely the type of planning today’s FERC decision affects.
Since the beginning of the Biden administration, FERC has been a key battleground for the future of energy policy. In 2022, Manchin blocked the reappointment of Richard Glick to the Commission, even though he had been serving as its chair; another commissioner left at the end of his term last year, and their replacements have not yet been confirmed. The Commission’s number will dwindle yet again when Clements’ term expires in June, assuming the Senate hasn’t acted by the end of its current session, which would leave FERC without a quorum.
The three-member commission is therefore trying to act as quickly as it can. “This rule can not come fast enough,” Phillips said.

The company managed to put a positive spin on tariffs.
The residential solar company Sunrun is, like much of the rest of the clean energy business, getting hit by tariffs. The company told investors in its first quarter earnings report Tuesday that about half its supply of solar modules comes from overseas, and thus is subject to import taxes. It’s trying to secure more modules domestically “as availability increases,” Sunrun said, but “costs are higher and availability limited near-term.”
“We do not directly import any solar equipment from China, although producers in China are important for various upstream components used by our suppliers,” Sunrun chief executive Mary Powell said on the call, indicating that having an entirely-China-free supply chain is likely impossible in the renewable energy industry.
Hardware makes up about a third of the company’s costs, according to Powell. “This cost will increase from tariffs,” she said, although some advance purchasing done before the end of last year will help mitigate that. All told, tariffs could lower the company’s cash generation by $100 million to $200 million, chief financial officer Danny Abajian said.
But — and here’s where things get interesting — the company also offered a positive spin on tariffs.
In a slide presentation to investors, the company said that “sustained, severe tariffs may drive the country to a recession.” Sounds bad, right?
But no, not for Sunrun. A recession could mean “lower long term interest rates,” which, since the company relies heavily on securitizing solar leases and benefits from lower interest rates, could round in the company’s favor.
In its annual report released in February, the company mentioned that “higher rates increase our cost of capital and decrease the amount of capital available to us to finance the deployment of new solar energy systems.” On Wednesday, the company estimated that a 10% tariff, which is the baseline rate in the Trump “Liberation Day” tariffs, could be offset with a half percentage point decline in the company’s cost of capital, although it didn’t provide any further details behind the calculation.
Even in the absence of interest rate relief, a recession could still be okay for Sunrun.
“Historically, recessions have driven more demand for our products,” the company said in its presentation, arguing that because their solar systems offer savings compared to utility rates, they become more attractive when households get more money conscious.
Sunrun shares are up almost 10% today, as the company showed more growth than expected.
For what it’s worth, the much-ballyhooed decline in long-term interest rates as a result of Trump’s tariffs hasn’t actually happened, at least not yet. The Federal Reserve on Wednesday decided to keep the federal funds rate at 4.5%, the third time in a row the board of governors have chosen to maintain the status quo. The yield on 10-year treasuries, often used as a benchmark for interest rates, is up slightly since “Liberation Day” on April 2 and sits today at 4.34%, compared to 4.19% before Trump’s tariffs announcements.
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.
Riverside Clean Air Carshare
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.
Republicans Mark Amodei of Nevada and Celeste Maloy of Utah introduced the measure late Tuesday night.
Late last week, the House Committee on Natural Resources released the draft text of its portion of the Republicans’ budget package. While the bill included mandates to open oil and gas leasing in Alaska’s Arctic National Wildlife Refuge, increase logging by 25% over 2024’s harvest, and allow for mining activities upstream of Minnesota’s popular Boundary Waters recreation area, there was also a conspicuous absence in its 96 pages: an explicit plan to sell off public lands.
To many of the environmental groups that have been sounding the alarm about Republicans’ ambitions to privatize federal lands — which make up about 47% of the American West — the particular exclusion seemed almost too good to be true. And as it turned out in the bill’s markup on Tuesday, it was. In a late-night amendment, Republican Representatives Mark Amodei of Nevada and Celeste Maloy of Utah introduced a provision to sell off thousands of acres in their states.
The maneuver, which came at nearly midnight, left many Democrats and environmental groups deeply frustrated by the lack of transparency. “The rushed and last-minute nature of this amendment introduction means little to no information is available,” the Southern Utah Wilderness Alliance said in a statement Wednesday.
While early reports had suggested the proposed sell-off would consist of around 11,000 acres of land in total between the two states, that number was arrived at in part due to the delayed release of maps, as well as an apparent malfunction with Amodei’s mic as he was discussing the parcels in Nevada, a communications adviser working with public land groups to analyze the amendment told me Thursday. It now looks as if the amendment offers up approximately 11,500 acres of land in Utah alone, based on acreage numbers included in the text.
Nevada’s parcels don’t include firm numbers, and public land groups are basing their estimates on eyeballing the maps prepared at the request of Amodei, as well as “other bits of information.” Democratic Senator Catherine Cortez Masto has estimated, for example, that the amendment proposes selling up to 200,000 acres of public land in Nevada’s Clark County, though some groups believe the acreage in the state could be much higher — totaling 500,000 acres across Utah and Nevada, or potentially even more.
House lawmakers appeared still to be at odds during a Wednesday morning press conference to announce the creation of a Bipartisan Public Lands Caucus. Rather than putting on the united front suggested by the working group’s name, former Secretary of the Interior and Montana Republican Ryan Zinke argued seemingly in defense of the amendment, saying, “A lot of communities are drying up because they’re looking to public land next door and they can’t use it.” Michigan Democrat Debbie Dingell then took the mic to say, “I would urge all of us that the hearings — it’s not done in the dead of night, and that we have good, bipartisan discussions with everybody impacted at the table.” (Zinke later said that he told Republican leadership “I strongly don’t believe [land sales] should be in the reconciliation bill,” and that the amendment represents his red line: “It’s a no now. It will be a no later. It will be a no forever.”)
Despite the cloak-and-dagger way Republicans introduced the amendment, there are several clues as to what exactly Amodei and Maloy are up to. Republican Senator Mike Lee of Utah has aggressively pushed for the sell-off of public lands, including introducing the Helping Open Underutilized Space to Ensure Shelter (HOUSES) Act, which would “make small tracts of [Bureau of Land Management] land available to communities to address housing shortages or affordability.” Critics of the bill have called it the “McMansion Subsidy Act” and have argued — as the Center for Western Priorities’ Kate Groetzinger, does — that it would “do little to address housing issues in major metros like Salt Lake City and the fact that the current housing shortage is due largely to a lack of home construction, not land.” The Center for Western Priorities also contends that it “contains very few restrictions on what can be built on federal public lands that are sold off under the program.” Notably, Lee and Maloy have worked closely together in the past on transferring federal land in Utah to private ownership.
The land singled out in the Tuesday amendment includes BLM and Forest Service parcels in six counties in Utah and Nevada that “had already been identified for disposal by the counties,” Outdoor Life notes. While some land would be sold with “the express purpose of alleviating housing affordability,” the publication notes that “other parcels, including those in southern Utah, don’t have a designated purpose.”
One communications director at a regional environmental group pointed out to me that the amendment proposes no parcels on the Wasatch Front in and around Salt Lake City, where around 82% of the state’s population lives and where such a high-density housing case could be made. Instead, many of the parcels are located a four- to five-hour drive away in the more remote Washington County. Conspicuously, a number of the parcels abut roads, potentially teeing up highway expansions. One parcel is even adjacent to Zion National Park — a prime location for an expensive development or resort. As Michael Carroll, the BLM campaign director for the Wilderness Society, warned E&E News, it’s in this way that the bill appears to set “dangerous precedent that is intended to pave the way for a much larger scale transfer of public lands.”
While many Republicans contend that states can better manage public lands in the West than the federal government can (in addition, of course, to helping raise the $15 billion of the desired $2 trillion in deficit reductions across the government to offset Trump’s tax cuts), such a move could also have significant consequences for the environment. Turning over public lands to states — or to private owners — could also 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.
Reducing BLM land could also limit opportunities for solar, wind, and geothermal development; in Utah, the agency has identified some 5 million acres of public land, in addition to 11.8 million acres in Nevada, for solar development. While there are admittedly questions about how much renewable permitting will make it through the Trump BLM, it’s also true that solar development wouldn’t necessarily be the preference of private landowners if the land were transferred.
Tuesday’s markup ultimately saw the introduction of more than 120 amendments, including a Democratic provision that would have prohibited revenue from this bill from being used to sell off public lands, but was easily struck down by Republicans. In the end, Amodei and Maloy’s amendment was the only one the committee adopted. Shortly afterward, the lawmakers voted 26-17 to advance the legislation.
