Want a deal on a heat pump? Team up with your neighbors.
Jun 8, 2026

Bulk buying is a tried-and-true way to get discounts on rooftop solar. Now programs aimed at heat pumps are popping up too, helping people save thousands of dollars.

Last year, Marie Tai needed a better way to keep her condo cool. Her window air-conditioning units were borderline ineffective, even running at full blast. Summers have been getting more intense in Tai’s Boston neighborhood because of a rapidly warming climate, and she had just adopted a 16-year-old cat named Mittens, who was still recovering from being hit by a car.

Tai had already been considering a heat pump, an all-electric appliance that heats and cools spaces and lets homeowners ditch polluting fossil fuels. But three contractors had quoted her prices ranging from about $28,000 to $40,000. Tai, who heads finance and administration at Harvard University’s Project Zero, thought those estimates seemed excessive for her 1,000-square-foot, two-bedroom place. So she had hit pause on the project.

But with Mittens’ well-being front of mind, Tai renewed her heat pump search last spring. Through Facebook, she found an opportunity to participate in a program that aggregates demand, organized by Laminar Collective, a local startup that does research on the tech and coordinates installations.

These heat pump group-buy initiatives let installers purchase equipment in bulk and spend less time chasing leads, accruing savings that they can pass on to customers. Tai, tantalized by Laminar’s menu of low prices for a heat-pump setup, decided to give it a shot.

After a representative from the startup visited her home to check what heat pump size and configuration would fit her needs, Tai signed up for a ductless minisplit system for $20,000 — thousands less than even her lowest initial quote. She then also took advantage of an additional $8,500 state rebate and eight-year financing with 0% interest.

The new equipment has been life-changing, Tai said.

She no longer has to buy fuel oil for heating in the winter, and the heat pump is so efficient that last year she saved roughly $1,300 on her energy bills. In contrast to the old, noisy window ACs, the new system’s wall-mounted, air-filtering indoor units ​“are so quiet,” she said. Her allergy symptoms have improved. And Mittens is comfortable and doing well, she noted. ​“I couldn’t be happier.”

Like Tai, homeowners in communities across the U.S. are signing up for an unusual way of buying heat pumps: together. Companies, nonprofits, and local governments are increasingly offering programs that coordinate consumer demand to secure meaningful discounts of around 10% to 20%, which can translate to roughly $3,000 to $6,000 per installation. It’s like a group buying a pack of muffins at Costco rather than each buying a muffin at Starbucks.

The bulk-buy approach is taking off as the Trump administration demolishes electrification incentives. Last year, the Republican-led Congress eliminated a $2,000 federal tax credit for home heat pumps. Late last month, the administration said that it won’t allow home energy-efficiency rebates to be used by people looking to get off gas.

While heat pumps reduce pollution and typically cut owners’ energy bills, they can be a pricey proposition up front. Whole-home installations typically range from $17,000 to $30,000, depending on the property size, insulation, climate, and many other factors, according to electrification advocacy nonprofit Rewiring America.

“Even though homeowners often save significantly over time, the first quotes can bring real sticker shock,” said Cole Merrick, founder and CEO of VoltHub, an online heat-pump installation marketplace.

VoltHub and heat-pump general contractor Vayu organized a California group-buy program this spring to serve the counties of Los Angeles and Orange and the greater San Francisco Bay Area. They’re offering another one this summer.

Most heating, ventilation, and air-conditioning replacements are emergencies, and these jobs will continue to make up the majority of Vayu’s business, said founder and CEO Shreyas Sudhakar. But for households that can hold off on getting a heat pump installed, group buys are ideal, he noted.

The process entails a waiting period, which can be several weeks to about six months, as the slots fill up and the installer determines the final pricing. The installer then confirms individual quotes with customers — who can decide not to move forward without penalty — and schedules the work.

Heat pump group buys come in different forms. They can be organized at the grassroots level, offered by a contractor, or run by a third party that aggregates demand over a limited time window. Through a competitive bidding process, the third party vets qualified installers and chooses one or more to carry out the jobs.

The collective bargaining approach has succeeded in the past. Nonprofit Solar United Neighbors has led similar group buys for rooftop solar since 2007, helping thousands of households net deals on installations.

Now, the organization is partnering with iChoosr, an international company that helps households electrify, in order to get group deals for heat pumps, too. Using iChoosr’s Switch Together platform, people in select areas can sign up to unlock group discounts for the all-electric appliance, as well as solar and batteries. Since 2023, more than 5,100 U.S. homeowners have gotten their solar panels or batteries via iChoosr, which earns a fee from participating vetted installers for jobs they get through the platform, said Fred Wu, a director of community engagement for the company.

iChoosr was already running successful bulk-purchasing programs for heat pumps in the U.K. and the Netherlands, and launched its first offerings in the U.S. last year with Solar United Neighbors. They opened one program in the Colorado Front Range and another in the Washington, D.C., area in July, closed those lists in September, and finished up the installations — for about 90 households — by the end of the year.

On the heels of that success, iChoosr reran group buys in both regions this spring. More than 1,000 households have signed up expressing interest so far.

This year, the company will also launch new programs in the metro areas of Houston and Dallas, Chicagoland, and northern Arizona around Flagstaff, partnering with nonprofits and local governments at no cost to them, Wu said.

For contractors, these bulk-buy initiatives are a boon.

They cut down on the installers’ sales and marketing costs, thanks to word of mouth and publicity from third parties like iChoosr. Home electrification contractor Elephant Energy, which is working with iChoosr to deploy the Colorado heat-pump installations, saves about $300 per project, said CEO and co-founder DR Richardson. Elephant has also run its own community bulk buys across its California, Colorado, and Massachusetts markets, he noted.

Group-buy initiatives smooth out demand by allowing for planned installations when business naturally slumps. Heating, ventilation, and air-conditioning work is highly seasonal, with most people calling an HVAC technician during the first heat wave or cold snap.

“For a lot of businesses, two months will make up 70% to 80% of the revenue for the year,” said Sudhakar of Vayu. ​“So to be able to have some guaranteed revenue that is on the books and [can] fill downtime is really valuable.”

But heat pump group-buying programs aren’t ubiquitous yet. Wu of iChoosr recommends that homeowners who are interested but not in a rush contact city and county leaders to let them know that they’d like to get a bulk deal going in their area.

“We’re continuously trying to expand the program,” Wu said. ​“The first thing we need … is a local government that wants to bring this to their constituents.” These partnerships lend credibility and visibility to the group initiatives, since local governments help promote them.

Tai in Boston was grateful to be part of Laminar Collective’s heat-pump bulk buy. It not only helped her save money but also provided her time to get her questions answered without the sales pressure she felt from one-on-one solicitations. ​“It’s empowering,” she said. After she told her neighbor about her experience, they got their heat pump that way, too.

Why is Massachusetts sitting on $64M in EV-charger funding?

Despite the state’s political embrace of EVs, it has built zero chargers nearly four years after receiving federal funds from the Biden administration.

For all the concern about lost federal funding courtesy of the Republican trifecta in Washington, Massachusetts still has not deployed a single electric vehicle charger through a Biden-era program that President Donald Trump has left intact.

The Bay State is sitting on the roughly $64 million it was awarded through the National Electric Vehicle Infrastructure (NEVI) program, a $5 billion federal initiative authorized through the 2021 bipartisan infrastructure law meant to strategically dot the nation’s major highways with charging infrastructure that would make it easier for EV drivers to reliably travel greater distances.

Two years ago, Massachusetts selected three vendors to identify locations for NEVI charging stations and then build and maintain them. Only contracts with two of those companies, however — Applegreen and Global Partners — are signed, the state’s Department of Transportation confirmed to CommonWealth Beacon, leaving open questions about the viability of the third vendor, Weston & Sampson.

Now, nearly four years after receiving federal approvals, no EV chargers on Massachusetts’s major roadways through NEVI are up and running, MassDOT also confirmed.

It’s not clear what exactly is causing the holdup. CommonWealth Beacon filed a public records request to view the contracts with the two companies to ascertain whether there are deadlines associated with charger installations, but MassDOT did not provide those contracts in time for publication.

“The slowness of adoption here is mystifying,” said Jim Aloisi, a former state transportation secretary who now lectures at the Massachusetts Institute of Technology and serves on the board of the advocacy group TransitMatters. ​“If your approach to transportation sector decarbonization is largely about the transition to EVs, then you should be spending a fair amount of effort accelerating the process of getting people to adopt EVs, and one way to do that is obviously to roll out the NEVI initiative. That’s the disconnect.”

MassDOT didn’t respond to questions about why the pace of NEVI work has been so slow. The department’s ​“conservative” projections in 2022 found that NEVI funding would be sufficient for building 92 charging ports.

Some officials serving on the state’s Electric Vehicle Infrastructure Coordinating Council, which was established in 2022 to help create an equitable and reliable charging network, also appear to be in the dark. Eric Bourassa, who is a member of the group and serves as the director of transportation for the Metropolitan Area Planning Council, said that he’s ​“not privy to the details of what’s holding it up,” but that ​“everyone would agree that the pace of NEVI deployment in Massachusetts has been disappointing.”

So far, the two signed NEVI vendors have spent close to $4 million, according to Marshall Hook, a MassDOT spokesperson, all of which are for ​“development-focused” activities like engineering, permitting, and procurement.

There have been signs of progress. Applegreen has placed an order for EV charging equipment for locations in Greenfield and Newburyport and is targeting late July to begin construction, Hook said. Global Partners, meanwhile, has been approved to place orders on equipment and is finalizing plans to install chargers in Lancaster, Wrentham, and Raynham.

James Cater, senior director for sustainability strategy and innovation at Global Partners, said in a statement that the company is ​“happy” to be working on Massachusetts’s NEVI program and is beginning the procurement process for contractors for their initial charging sites ​“soon.”

Applegreen and Weston & Sampson did not respond to requests for comment.

Yet the slow adoption rate through NEVI continues to bewilder transit advocates given the state’s relatively small size and political embrace of EVs. Neighboring states like Rhode Island, New York, and Vermont boast a significant stock of NEVI chargers, in addition to more sprawling red states like Utah and Ohio.

“We should be capitalizing on every opportunity that we have available to us,” said Anna Vanderspek, electric vehicle program director at the Green Energy Consumers Alliance. ​“MassDOT should explain why it’s taken so long and what timetable we can expect now.”

The uptake on NEVI has been slow nationwide: Just 19 states have at least one operating EV charger funded through the program, according to the National Association of State Energy Officials. Adie Tomer, a senior fellow at Brookings Metro who specializes in infrastructure policy, said that poor capacity more broadly across states has stifled their ability to quickly implement the program as they wrangle procurement processes, permitting, and electrical grid transmission complications.

“There were plenty of ingredients here to have paralysis by analysis,” Tomer said. ​“Government officials are naturally going to be risk averse, especially with newer programs, and officials needed to learn on the fly. NEVI hits all those sweet spots, so it’s not terribly surprising that deployments are coming along slower than initially hoped.”

The data around Massachusetts’s EV push offers a mixed bag. On one hand, the state’s slow crawl on NEVI is contrasted by its relative success deploying EV chargers in general. State data show the Commonwealth ranking fourth in the country for charging ports per capita after a sharp increase in installments over the past few years.

Yet, Massachusetts still has about 2,000 charging ports less than what it estimates it needs, according to the most recent state climate report card.

The state also remains significantly behind its targets for registered electric cars and trucks as it races to cut its greenhouse gas emissions in half compared to 1990 levels by 2030. There are just 735 medium-and-heavy-duty EVs on the road, a sliver of the 3,200 called for by the end of 2025.

On light-duty EVs and plug-in hybrids, Massachusetts has about 166,000 such cars, short of the 200,000 needed by last year. Last year, the Healey administration also delayed an EV sales requirement.

Part of convincing consumers to purchase generally more expensive electric cars involves easing ​“range anxiety,” the worry of EV drivers about whether they’ll make it to their destination or the next charging station — one of the core functions of the NEVI program.

Notably, Massachusetts has also placed its NEVI bet on two companies that have been at intense odds with each other in the past year.

Applegreen and Global Partners — the two vendors with signed contracts with the state for NEVI work — have been at the center of a bitter dispute over the state’s efforts to redevelop 18 highway service plazas. MassDOT awarded Applegreen that major contract last year, but the company backed out after losing bidder Global Partners sued the state and fought to block the deal over allegations that the process was unfair.

MassDOT is now preparing to rebid the whole project, and the state inspector general ridiculed the agency for having ​“too many flaws” in its process that has attracted the ire of Beacon Hill.

The bad blood between Applegreen and Global Partners may not spill over into how fast the companies can deploy chargers on the state’s major highways since they will be responsible for separate individual sites, minimizing the necessity for direct collaboration.

But the situation speaks to the challenges of complicated procurements and the fragility of the private market to perform this sort of work, when a small pool of companies competes for similar supplies and subcontractors and could be vulnerable to price spikes.

“The word ​‘irony’ is a good one,” Aloisi said. ​“It may be that there’s just not a lot of good competition in this area. What does that landscape look like, and who wants to play in that sandbox? And it may be that the unfortunate answer is not too many players, so you’re stuck with the same.”

NYC’s big, clean power line is officially up and running
Jun 5, 2026

The Champlain Hudson Power Express is bringing tons of hydropower to the city — but amid years of drought, can Canada spare the clean electricity?

New York City has a lot to celebrate this week. The Knicks are in the finals, the Mets actually won a game, and the city is now a big step closer to meeting its clean energy targets.

Tons of clean electricity is finally flowing from Canada to New York City via the 1.25-gigawatt Champlain Hudson Power Express, a big power line also known as CHPE (pronounced ​“chippy”). The city is now able to power all of its government operations and cover 20% of citywide electricity demand — equivalent to that from 1 million homes — with hydro shipped in by utility Hydro-Québec.

CHPE, along with the eventual completion of the Empire Wind project off Brooklyn, is essential to attaining New York City’s goal of cutting greenhouse gas emissions 80% by 2050. Last year, the city got nearly 90% of its electricity from fossil fuels, and just a measly 3% from hydro.

It’s a long journey from Quebec down to Queens, but it’s been an even longer one to get the power line built. Plans for CHPE began more than a decade ago, and the project faced opposition from environmental groups and residents as discussions progressed. But in the end, CHPE came online a few weeks earlier than expected, just in time to shore up power supplies ahead of summer’s demand spikes.

CHPE is one of two major transmission projects that recently launched to bring Canadian hydropower into the Northeastern U.S. Electricity started flowing into Maine via the New England Clean Energy Connect line earlier this year, capping a decade of controversy that saw the project scuttled and relocated multiple times.

But other challenges remain for both New England Clean Energy Connect and CHPE. Some experts are questioning whether Hydro-Québec can actually generate enough electricity to share with the U.S. When all these transmission line discussions first started, Hydro-Québec was running on 15 years of abundant rain flow, Pierre-Olivier Pineau, a professor of energy sector management at HEC Montréal, tells Marketplace. Over the past three years, though, the province has faced consistent drought that has diminished Hydro-Québec’s reservoirs.

For its part, Hydro-Québec said earlier this year that its reservoirs are prepared to weather drought conditions. But Quebec also has decarbonization goals of its own to meet, and demand is rising from data centers and industry — two factors that weren’t so big when the utility agreed to sell off its hydropower more than a decade ago.

Trump tries to save coal — again

The Trump administration is unleashing $700 million to prop up the coal industry, even as more evidence piles up to show it isn’t worth the expense.

On Thursday, Trump announced that he’d use wartime powers under the Defense Production Act to funnel $425 million to boost 13 coal plants across the U.S. Another $75 million will go toward building an export terminal in Oakland, California, and $185 million is slated for the construction of two new coal plants in Alaska and West Virginia.

The move is just the latest in the administration’s coal-bolstering campaign, which has also seen Trump use an ​“energy emergency” to justify keeping old coal plants from shutting down. But as Canary Media’s Kari Lydersen reported this week, there doesn’t seem to be much of an emergency going on: One Indiana coal plant ordered to stay open has actually been broken since February, and experts say the grid will be just fine without it this summer.

Data center discontent is reaching new heights

More and more Americans are getting fed up with data centers, and that pushback is turning into policy action.

A survey out this week from Heatmap shows that 71% of Americans say they’d somewhat oppose or strongly oppose a data center being built near where they live. Just 42% said the same last fall. The mounting blowback comes alongside a wave of data center project cancellations, according to Heatmap: At least 20 projects were called off in the first quarter of this year.

A wave of cities and states are meanwhile looking to head off data center projects altogether. The New York State Legislature passed a one-year moratorium on new construction on Thursday, though it’s unclear if Gov. Kathy Hochul (D) will sign it into law. Residents of Monterey Park, California, meanwhile took their discontent to a new level, voting this week to become the first U.S. city to outright ban data center development.

Ohio has blocked a lot of wind and solar. Its residents pay the price.
Jun 5, 2026

The clean energy projects thwarted by state lawmakers could have gone a long way toward meeting spiking energy demand, lowering bills, and eliminating pollution.

Last week, the Ohio Supreme Court blocked a permit for what would be the state’s largest solar installation. The 800-megawatt Oak Run Solar Project still has a pathway to completion — the court reversed only one part of the state siting board’s prior approval — but it remains unclear how things will play out.

This is just the latest example of how state lawmakers and other officials have obstructed renewable energy development in Ohio. In total, they have thwarted more than 5.3 gigawatts of solar and wind projects over the last dozen years.

So says a recent analysis released by Save Ohio Parks, which opposes fracking and oil and gas extraction from public lands.

“It’s a lot of inexpensive power that we don’t have available to us. And it means fewer choices for consumers,” said Tom Bullock, executive director for the Citizens Utility Board of Ohio. ​“Boy, would that come in handy right now when electricity prices keep going up, up, up.”

Ohio, like many other states, is facing rising utility bills as well as massive new energy demand due to a wave of proposed data centers. The Save Ohio Parks report contends that clean energy could have helped rein in those energy costs while meeting a huge chunk of data centers’ demand if Ohio had allowed more development. The 5.3 GW of blocked clean energy would have also avoided large amounts of greenhouse gas emissions and local air pollution.

The state stepped up its pushback on wind and solar as each of those clean energy sources became more cost-competitive with fossil fuels and nuclear power.

A 2014 law that more than doubled property-line setbacks for wind turbines effectively blocked over 3.3 GW of utility-scale projects in the state, the report notes. Efforts in 2017 to roll back those restrictions failed, leaving Ohio among the nation’s most restrictive states for wind power.

“The economics of a wind farm don’t work when you need that amount of setback from a property line,” said Rachel Kutzley, a Save Ohio Parks board member who worked on the report.

Seven years later, Gov. Mike DeWine signed Senate Bill 52, which lets counties ban new solar projects above 50 MW of capacity and ​“economically significant” wind farms able to produce more than 5 MW of electricity. SB 52 doesn’t let counties ban power plants that use fossil fuels or nuclear power.

Neither the Save Ohio Parks report nor a February 2026 paper in the journal Frontiers in Sustainable Energy Policy quantified how much clean energy generation the bans by Ohio counties have prevented.

Projects that were already in grid operator PJM Interconnection’s queue are not subject to outright bans under SB 52. The Ohio Power Siting Board, however, can deny permits for individual projects — and since 2021 it has rejected eight installations, making Ohio one of the toughest states for developing clean energy. The board has routinely referenced local government opposition when rejecting projects.

Those eight rulings alone have killed more than 1.1 GW of solar generation.

Developers withdrew five other applications for projects that would have added roughly another 1 GW, after adverse recommendations from the Power Siting Board’s staff or significant local pushback made it likely the full board would deny permits. The Kingwood Solar case, which challenges the board’s deference to local government opposition, is due to be decided soon.

Matt Schilling, a spokesperson for the Ohio Power Siting Board and Public Utilities Commission of Ohio, said he did not have a comment on the report from Save Ohio Parks. ​“However, I will observe OPSB has approved 49 solar projects across Ohio with nameplate capacity totaling 9,250 MW,” he added.

Only about one-third of those approvals were for permit applications filed after SB 52’s effective date.

It’s not just solar and wind — Ohio has also stymied energy-efficiency efforts over the years, which would have additionally cut down on pollution and saved money for residents. The Save Ohio Parks’ report doesn’t consider the effects of the state’s infamous House Bill 6, which eliminated utilities’ energy-efficiency requirements after 2020.

Those impacts would have been quite sizable, said Mike Specian, a utilities manager with the American Council for an Energy-Efficient Economy, who shared his separate analysis with Canary Media.

If utilities had continued to achieve energy savings for customers after 2020, the cumulative savings could have been as much as 70 terawatt-hours, or 70 million megawatt-hours, Specian said. That high number is partially because energy-efficiency investments provide benefits, on average, for nearly a decade. ​“Those savings deliver year over year over year,” he said.

The mix of thwarted solar and wind projects alone likely would have displaced 7.1 million metric tons of carbon dioxide emissions from fossil fuel plants, said Ben King, a director with research firm Rhodium Group’s energy and climate practice. Carbon dioxide is a major greenhouse gas that drives human-caused climate change.

King based that estimate on results from the Environmental Protection Agency’s Avoided Emissions and Generation Tool. Ohio’s lost clean energy generation could have cut millions of metric tons of pollution from sulfur dioxide, nitrogen oxides, and other pollutants with harmful health effects as well, the EPA tool shows.

The lost clean energy opportunities are also impacting consumers’ finances, although it’s hard to tell exactly how much because electricity prices reflect multiple components.

Ohio gets about 7.5% of its electricity from wind and solar, compared with 80.6% from coal and gas, according to federal data for 2025.

When it comes to the electricity dispatch market, ​“the generation we have less of is the least expensive in Ohio,” said Ashley Brown, a former member of the Public Utilities Commission of Ohio. Solar and wind have no fuel costs, so their marginal costs for producing energy are very low. That competition also reins in bidding by producers of other forms of electricity, particularly fossil fuels, whose prices have soared even higher because of the Trump administration’s war on Iran.

“It really does force enormous price pressure on other forms of generation,” Brown said.

Less solar and wind generation has some effect on the capacity market, the mechanism PJM uses to ensure it will have enough energy producers available to meet future demand spikes. Last year, capacity made up about 16% of the wholesale cost of electricity, noted Jeff Shields, PJM’s senior manager for external communications. Even though renewables count less toward capacity than other types of energy, ​“we can use all the capacity we can get,” he said.

Renewables’ ability to come online more quickly than other sources could do a lot to curb inflation, said Bullock at the Citizens Utility Board of Ohio. ​“Unless Ohio takes action, consumers are locked on this escalator. We’re strapped to the escalator that keeps going up.”

Nevertheless, some Ohio lawmakers seem intent on making it harder — not easier — to build new clean energy projects in the state.

SB 294, reported out of the Senate Energy Committee on June 2, would further cement the state’s preferences for natural gas and nuclear power — and potentially make it even harder to get approval from regulators for solar and wind.

Electric cars are starting to take over the world

Despite sluggish EV sales in the U.S., it’s full steam ahead for electric vehicles in most other regions.

Electric vehicles may be struggling to find buyers in the U.S. — but they’re making inroads elsewhere.

A record-breaking 28% of new cars sold this year will be battery-powered, according to new data from the International Energy Agency. That’s a big deal: Driving around in gas-guzzling vehicles spews tons of planet-warming and health-harming pollution into the atmosphere.

Made with Flourish • Create a chart

The latest projections come even as the Trump administration’s attacks on electric vehicles stymie sales in the U.S., the world’s second-largest car market. The country is a massive laggard when it comes to EV adoption, with electric models making up just around 10% of new car sales. New EV sales are expected to decline for the second year in a row in the U.S., though used models are surging in popularity.

But outside the U.S., the picture is very different. The clearest example of that contrast is China, the world’s biggest car market and the global leader in electric vehicle and battery manufacturing. Nearly 60% of cars sold in China this year will be electrified.

EV sales are growing rapidly across the rest of Asia, too. This year, sales are expected to leap by over 50% across Asian countries other than China, IEA found, driven in large part by the availability of super affordable Chinese EV models.

In Europe, which has strong emissions standards that push consumers toward EVs, sales are growing especially fast. This year, EVs will make up one-third of new cars sold in the region, powered not only by EV-adoption poster child Norway but also by rapid uptake in Germany, the U.K., and Turkey.

It’s worth emphasizing that these figures are for new car sales only. It will take longer for EVs to become the most popular type of car on the road: Right now, they make up just about 5% of the global car fleet.

Still, we’re well past the peak for gas car sales, and the trends are in favor of EVs. By 2035, the IEA expects half the new cars sold worldwide to be EVs. In China and the E.U., 90% of new cars could be EVs by that time.

And then there’s the war in Iran, which has caused the price of gasoline to surge and even resulted in fossil-fuel shortages in some countries. The crisis is adding more urgency to the transition to electric vehicles, particularly for nations that rely on imported oil. As EVs get cheaper and the volatility of fossil fuels becomes more apparent, economics may start to drive the transition from gas cars faster than climate goals ever could.

Why North Carolina’s electric co-ops are turning to grid batteries
Jun 4, 2026

From the suburbs to the barrier islands, the state’s local cooperatives are using aggregated battery systems to weather outages and protect consumers’ wallets.

In July 2022, a fierce summer storm rocked Wake Electric, a North Carolina cooperative serving nearly 60,000 households and other customers from the dense suburbs of Raleigh, the state capital, to rural areas along the Virginia border and in the coastal plain. Wind downed lines and knocked out power for thousands for over seven hours.

“It was one of these very difficult outages where we had a line laying across a road,” said Don Bowman, the co-op’s senior vice president and assistant general manager. ​“We had to coordinate a lot of activities, and it took us a while to get this power back on.”

But Eagle Chase, a small housing community equipped with a propane-fueled generator and a 1-megawatt Tesla battery pack, was almost completely unscathed. The devices form a microgrid that can function without the co-op’s larger distribution system of poles and wires.

“The success story,” Bowman said, ​“is the Eagle Chase development saw an outage of less than about 58 milliseconds.”

The Eagle Chase battery is among three storage systems in Wake Electric’s territory. The second, in Wake Forest, is a 1-megawatt-hour battery paired with a 500-kilowatt solar farm; its purpose is to dispatch solar electrons when the sun doesn’t shine. The third, a 5-megawatt battery located at the co-op’s main substation, stores power that can be discharged when supplies are constrained and electricity prices are high.

The systems illustrate three key advantages of battery storage, Bowman said: providing resiliency, increasing the reliability of renewable energy, and responding to periods of high demand.

“We have three systems, and I think that we check all three of those boxes differently with each of the projects,” he said.

Wake Electric isn’t alone. As of April 2025, rural co-ops across North Carolina had 43 battery projects operating or in development, according to the National Rural Electric Cooperative Association. Co-ops here were spearheading more grid batteries than those in any other state; Alaska was a distant second with 13 projects.

The co-ops say they aren’t trying to win any national contests. They’re just trying to do right by the members they serve.

“Community support is one of the pillars we drive toward,” said Erik Hall, a director at the North Carolina Electric Membership Corp., a statewide entity that owns the battery assets and provides generation and transmission for 25 rural cooperatives. ​“What can we do to support the membership?”

The battery investments are partly a response to challenges now sweeping the country: Skyrocketing demand from data centers and other factors are constraining supplies and triggering expensive grid upgrades, driving up the costs of electricity.

Storing electrons for use when demand is at its peak and prices are high is a huge money saver for these customer-owned nonprofits — especially as the costs of batteries are falling and federal tax credits for the resources are still available.

“What these battery systems have been able to do is really save folks money while increasing resilience, and helping with reliability sort of across the footprint,” said Rob Greskowiak, chief commercial officer for Lightshift Energy, a storage developer that has worked with several co-ops outside North Carolina, including in neighboring Virginia. ​“It’s really an economic story.”

Money isn’t the only motivator. Co-ops often serve far-flung corners of the state, where an investor-owned utility like Duke Energy would earn a meager profit. Many of these areas — from rugged mountains to fragile barrier islands — are also prone to outages from extreme weather.

That’s why almost a decade ago, Tideland Electric Member Corp. set up the state’s first cooperative-run microgrid on Ocracoke Island — complete with 62 solar panels, a battery pack, and a diesel generator. The system kept the power on for island residents in the summer of 2017, after a construction crew accidentally severed a transmission line to the mainland.

“The solar worked,” Heidi Smith, a Tideland co-op manager, said back then. ​“The Tesla batteries were able to add power to the system.”

North Carolina’s co-ops also have set a target of zeroing out their carbon emissions by midcentury, though, unlike Duke, they’re not required to by law.

“It’s in our mission statement to constantly be moving toward cleaner energy solutions,” Bowman of Wake Electric co-op explained.

The benefits and costs of the individual battery systems can be spread out among the co-ops and their millions of customers, since all these storage devices are managed by the North Carolina Electric Membership Corp.

“Having all of these assets is wonderful,” the corporation’s Hall said. ​“But if you can’t aggregate them and utilize them when they’re needed, then you’re not really bringing to bear the value of them.”

That means calling on the storage assets when high demand sends electricity prices soaring or dispatching them during extreme weather events to enhance reliability.

“I sound like I’m tooting our horn, and I am,” Hall said. ​“We’ve built one of the most innovative and capable [distributed energy resource management] systems in the country.”

“I don’t call it a virtual power plant, because it sounds very financial, economic,” he added. ​“Our systems are grounded in reliability.”

Still, not every move made by the state’s co-ops has been in lockstep with the clean energy transition. North Carolina Electric Membership Corp. is pursuing a large new gas-generation plant in Person County in conjunction with Duke and already owns two single-cycle, peaking gas plants outright. It’s also made a long-shot bid to the Federal Energy Regulatory Commission that, if successful, could upend how transmission upgrades are paid for and stall new solar from coming onto the grid.

The split screen just reinforces that batteries are not, for many adopters, first and foremost about curbing carbon emissions.

“North Carolina can be viewed as a leader in this space, but I think it’s important to reiterate that it’s not because of sustainability goals or clean energy goals,” Greskowiak said. ​“The economic case for battery storage is only going to grow. The rest of the country is catching up.”

DOE bars homes from using rebates to ditch fossil-fueled heating
Jun 3, 2026

The Trump admin’s new rules block Americans from accessing rebates for electric heat pumps if they previously had oil, natural gas, or propane systems.

This article originally appeared on Inside Climate News, a nonprofit, nonpartisan news organization that covers climate, energy, and the environment. Sign up for their newsletter.

Federal energy efficiency rebate programs will no longer cover a switch from fossil fuels to electricity for heating, according to long-awaited guidance from the Department of Energy.

The department published an update on how it will implement consumer programs with $8.8 billion in funding. The new provisions include eliminating use of diversity, equity, and inclusion considerations, among other changes.

This follows legal challenges after President Donald Trump issued an executive order last year, upon returning to office, canceling the release of funds from President Joe Biden’s Inflation Reduction Act, including rebates for home energy efficiency. A coalition of states successfully sued to restore the funding, obtaining an injunction in March 2025.

States have been waiting for the Department of Energy to reopen funding, a process that begins with this latest publication.

Clean energy and environmental advocates said the guidance was overdue and severely flawed.

Tony Sirna, deputy policy director for Evergreen Action, said it’s ​“flatly illegal” to eliminate funding for electrification through an agency’s guidance rather than passing a new law. ​“This is a deliberate effort to deny relief to millions of families at the exact moment they need it the most,” he said in a statement.

The guidance, dated May 29 and announced in a news release on June 1, covers the $4.3 billion Home Owner Managing Energy Savings, or HOMES, program and the $4.5 billion High-Efficiency Electric Home Rebate, or HEEHR, program, with additional guidance for Indian tribes participating in HEEHR.

The HOMES program provides up to $8,000 for households to make energy-efficient upgrades, including insulation, air sealing, heating and cooling equipment, water heaters, duct sealing, appliances, and lighting, according to the Department of Energy. The upgrades must reduce energy use by at least 20 percent to be eligible.

The HEEHR program provides up to $14,000 in rebates per household, which retailers and contractors can offer at the point of sale, and can be used for qualifying efficient electric equipment and appliances.

Congress and the Biden administration designed the programs to ensure that low-income and other disadvantaged households received a significant share of the benefits. The new guidance is changing this focus, citing the Trump administration’s opposition to considering diversity, equity, and inclusion in federal spending and the elimination of Biden’s Justice40 environmental justice initiative.

The guidance also eliminates the programs’ support for shifting from oil, gas, or other fossil fuels to electricity for home heating. Now, households can only get funding for heat pumps for new construction or if they already have electric heat, as opposed to the previous rules that encouraged people to switch away from fossil fuels.

Another change is that the Department of Energy now requires households to upgrade their insulation and air sealing before using rebates for new appliances.

Reaction was mostly negative from groups that push for improvements in energy efficiency.

“It’s a very standard playbook to incentivize fossil fuel companies and provide a lifeline to them,” said Srinidhi Sampath Kumar, director of the Sierra Club’s clean heat campaign, about the limits on fuel switching. ​“It’s absolutely been done in bad faith.”

Mark Kresowik, senior policy director for the American Council for an Energy-Efficient Economy, said in a statement that the programs ​“will help families make energy-saving improvements that lower their utility bills,” but he lamented the new limits on the programs.

The guidance is ​“a fundamental departure” from the intent of the programs, said Sam Friesen, managing director for buildings at Fresh Energy, a Minnesota-based environmental advocacy group. He added that the changes will muddy the waters for consumers who were making plans under the old rules and now need to follow the new ones.

Robin Yochum, buildings program director for the Southwest Energy Efficiency Project, a regional nonprofit based in Colorado, said she is pleased to see this step to implement the programs but is concerned about limits on fuel shifting.

“While there are certainly many electrically heated homes that deserve efficiency upgrades, helping households transition from propane, fuel oil, and natural gas to highly efficient electric technologies was one of the most transformative aspects of the original program design,” she said in an email.

Asked for a response, a Department of Energy spokesperson had this comment: ​“The Department of Energy has released common-sense revisions to program guidance to align requirements more closely with statutory requirements, advance affordability, ensure good stewardship of taxpayer dollars, and empower grantees to tailor their programs to local contexts and residents’ needs.”

State programs administer the money but the federal government must approve the state plans before the funds are released. Most states plus the District of Columbia have had at least some of their plans approved, as shown in a May 18 update from Atlas Public Policy.

Some already paid rebates based on the initial rules under the Biden administration. Those states now have three months to modify their programs to comply with the new guidance going forward.

South Dakota has declined to participate, and Idaho’s legislature has taken action to stop participating.

Consumers can contact their state energy offices to get more information about program availability.

House passes bipartisan measures to speed geothermal energy projects
Jun 3, 2026

The package of geothermal permitting reforms comes as Republicans and Democrats alike look to boost clean, 24/7 power supplies. Now it heads to the Senate.

The U.S. House just approved a bipartisan package of bills to accelerate geothermal energy as the nation clamors for more around-the-clock clean electricity.

The Geothermal Energy Advancement Act, or H.R. 5631, passed with broad support on Tuesday. The legislation — led by U.S. Reps. Jeff Hurd (R-Colo.) and Susie Lee (D-Nev.) — includes the text of six bills that tackle some of the key permitting and regulatory challenges that companies face when building and scaling geothermal systems.

The measures ​“seem like low-hanging fruit, but they can actually make a tangible difference as we try and develop projects,” Ben Brenner, who leads federal policy and outreach for the geothermal startup Zanskar, told Canary Media. ​“It’s a huge milestone for these bills to pass the House.”

Also on Tuesday, the House separately passed another geothermal bill — sponsored by Rep. Russ Fulcher (R-Idaho) — that aims to increase the frequency and consistency of geothermal lease sales on federal land.

America has been converting earth’s heat into electricity for nearly 70 years, beginning with The Geysers power plant in Northern California. Yet the carbon-free energy source still accounts for only 0.4% of the nation’s annual electricity generation, largely owing to geographical constraints.

A new generation of technologies has made it possible to extract heat from places without simmering hot springs and natural reservoirs. The startup Fervo Energy, which just went public, uses drilling techniques from the oil and gas industry to produce clean power from hot dry rocks. Zanskar combines artificial intelligence with boots-on-the-ground surveying to identify conventional but hidden heat resources in the U.S. West.

But so far, the federal government hasn’t adapted to meet the rising demand from developers for permits, land leases, and legal certainty, experts say. Over 90% of identified U.S. geothermal resources are beneath public lands, making the Department of the Interior a crucial player in the emerging industry’s growth.

“As technologies evolve, so must the regulatory landscape,” Terra Rogers, senior director of the Clean Air Task Force’s superhot rock geothermal program, said in a statement. She applauded Congress for taking practical steps toward ​“unlocking next-generation geothermal.”

Now, the geothermal bills head to the Senate, though it’s unclear when or how the chamber will act, E&E reported. However, Brenner said he sees ​“a real pathway toward Senate passage, whether as standalone legislation or as part of a broader permitting package.”

Originally, Hurd introduced H.R. 5631 to improve Interior’s own expertise on geothermal issues, including by creating the role of ​“ombudsman” — a point person within the Bureau of Land Management who can clear up confusion and resolve disagreements among field offices about geothermal permitting decisions.

The amended bill that passed this week also folds in five other measures:

  • H.R. 1077, the Streamlining Thermal Energy through Advanced Mechanisms (STEAM) Act, grants geothermal developers the same streamlined environmental permitting pathway, known as ​“categorical exclusion,” that oil and gas companies have to expedite exploration and development on certain public lands.
  • H.R. 301, the Geothermal Energy Opportunity (GEO) Act, requires Interior to process all applications for drilling permits and licenses under an existing geothermal lease within 60 days of completing required reviews.
  • H.R. 5638, the Geothermal Royalty Reform Act, clarifies that geothermal plants on the same lease pay royalties based on each individual facility’s time in service.
  • H.R. 5617, the Geothermal Gold Book Development Act, provides guidance to federal staffers by requiring the Bureau of Land Management to publish best practices for geothermal leasing and permitting.
  • H.R. 398, the Geothermal Cost-Recovery Authority Act, gives Interior the authority to recoup application and inspection fees from energy companies to expedite geothermal projects, similar to what the agency already does for wind, solar, and oil and gas.

Rep. Alexandria Ocasio-Cortez (D-N.Y.), who sponsored H.R. 398, said that speeding up geothermal deployment could help alleviate the nation’s skyrocketing electric bills. ​“At a time of extreme political polarization, this package shows that Congress can still come together on commonsense solutions to better the lives of the American people,” she said in a press release.

The measures will also likely benefit the developers of power-hungry data centers, such as Google and Meta, which are investing in geothermal projects to support their growing operations in Nevada and New Mexico, respectively. Both firms are members of the Corporate Energy Buyers Association, a trade group that advocates for a carbon-free energy system.

“There are few energy technologies that draw this level of bipartisan support, but geothermal energy is a reliable domestic resource with enormous potential to fuel our nation’s electricity needs,” Rich Powell, CEO of the association, said in a statement.

Geothermal’s ability to churn out power 24/7 appeals to both Republicans and Democrats grappling with energy-supply crunches in their states, though wind and solar paired with batteries can also deliver firm power in certain ideal locations. Late last month, a bipartisan group of governors from Arizona, Colorado, New Mexico, and Utah launched a coalition to ease financial and logistical hurdles that stand in the way of building potentially hundreds of gigawatts of geothermal capacity in the Mountain West.

Geothermal’s strong overlap with the oil and gas industry — in terms of tools, workforce, and investors — is another key reason why the Trump administration has shown support for the renewable energy source, even as it works to block wind and solar development.

Beyond the House bills, Brenner noted that other, bolder policy measures are needed to dramatically increase the scale and pace of next-generation geothermal deployment in the U.S. That could include increasing federal funding for research and exploration — efforts that are largely backed by equity and venture capital today — as well as for demonstration projects that help de-risk geothermal development in new areas.

“This is an incredibly positive step, but it is not the full picture,” he said of the legislation. ​“There’s a lot more work that has to happen.”

An update was made on June 3, 2026, to include Rep. Russ Fulcher’s legislation.

In Massachusetts, parked EVs will start feeding the grid this summer

Three electric school buses will kick-start the state’s groundbreaking vehicle-to-grid pilot program once school’s out, with more EVs to be added in the coming months.

After the school year ends in the Massachusetts towns of Acton and Boxborough, the district’s electric buses will mostly stay put in a parking lot. But they won’t sit idle all summer.

The three vehicles will charge up their nearly 200-kilowatt-hour batteries overnight, when the power supply is at its cleanest and cheapest, then send energy back to the grid from 4 p.m. to 7 p.m. on days when the grid is strained. The district will earn revenue for the power it shares, perhaps even enough to cover the costs of charging up during the school year, said Kate Crosby, energy manager for the Acton-Boxborough school district. Plus, the strategy will help lower the emissions and cost of the region’s electricity supply.

“The more we plug in batteries to the grid, the less we use peaker plants,” Crosby said. ​“They will help to stabilize the grid, help to reduce the cost of electricity for all ratepayers, and they’ll help make the grid cleaner.”

Acton-Boxborough’s school buses are the first vehicles to plug in to a Massachusetts program that aims to demonstrate and investigate the potential of ​“vehicle-to-everything” technologies, more commonly known as V2X. These systems use bidirectional chargers, which can power up a vehicle as well as send the energy stored in an EV’s battery back to a building or the grid.

Supporters say V2X technologies can yield a host of benefits. They can lower emissions by using stored energy generated at times when the grid is consuming less fossil fuel. They can help users offset their electricity bills by compensating them for power sent to the grid. They contribute to resilience when the power goes out. Plus, they can keep prices lower for everyone by sending cheaper power to the grid during times of high demand.

So far, however, widescale adoption has been elusive. Pilot programs across the U.S. and abroad have tested the possibilities, but they haven’t gained much traction in the face of high upfront costs, technical complexity, the huge variation among what equipment works with what vehicles, and the lack of established plans to compensate users for the power they pour back into the grid.

Massachusetts hopes its initiative will make some headway against these obstacles. At an event last week, the planners behind the demonstration program discussed what they’ve achieved so far, what they’ve learned along the way, and what problems remain.

The Massachusetts Clean Energy Center, an economic development agency, announced the demonstration program in early 2025, with the goal of giving away up to 100 bidirectional chargers to a variety of users. Participants were announced in February 2026: five school districts, four municipalities, and 30 residents. In order to understand how the systems function in a wide range of settings, the planners selected projects in all geographical corners of the state, and in rural, urban, and suburban areas served by 10 different utilities. The installations will include six different types of chargers plugging into eight different vehicles, from buses and pickup trucks to SUVs and compact hatchbacks.

“It’s not just about getting the right vehicle and the right chargers,” said Sally Griffith, transportation electrification program manager for energy consulting firm Resource Innovations, which is working with the state to run the program. ​“It’s about the whole system — how all of this needs to work together,” she said at the event.

Between 10 and 15 chargers are now installed and awaiting authorization to begin bidirectional charging. The rest are expected to be online by September.

Already, some challenges have been identified. The most pressing, speakers at the event said, have to do with finding a financial model that works.

For one, the systems are pricey: $15,000 to $40,000 for a residential setup, the Massachusetts Clean Energy Center estimates. Pilot programs can help defray costs for small numbers of users for a limited time, but a long-term, reliable compensation plan is needed to get any meaningful number of EV owners to make the leap.

But it turns out those compensation programs can be tricky to design. In Massachusetts, one major discovery so far has been the conflict between state solar incentives and the ConnectedSolutions program, which compensates battery owners for sending power onto the grid. Existing technology can’t tell the difference between electrons sent from solar panels and those coming from batteries. For a home with both solar panels and a bidirectional charger, it would be impossible to separate the solar power that should receive net-metering incentives from the EV battery power that would receive payment from ConnectedSolutions.

The Massachusetts Clean Energy Center had to immediately disqualify roughly 75% of the nearly 300 residential applicants for the V2X program because their homes had solar power, said Elijah Sinclair, the center’s senior program manager.

The state was aware there might be a conflict, but the scale took program planners by surprise, delaying the selection of participants and therefore the deployment of chargers.

One possible answer could lie in a program that compensates virtual power plants — networks of distributed energy resources like solar panels, batteries, and demand management — rather than providing different incentives for each component of the system, Steve Letendre, senior adviser at the Vehicle-Grid Integration Council, an EV charging advocacy group, told event attendees.

“We believe it’s a mechanism by which we can bring EVs onto the grid in a way that maximizes their value,” he said.

An unexpected bright spot so far has been the ease of interconnection, the process of formalizing agreements with utilities for hooking up an energy resource to the grid, Sinclair said.

“Utility interconnection was expected to be a big barrier,” he said. ​“But everyone has been just awesome to work with, and interconnection hasn’t slowed us down.”

The Massachusetts Clean Energy Center will collect data from participants for the rest of the year. By the end of the year, it aims to publish a comprehensive guidebook on what it’s learned about the cost, system design, and technical and regulatory barriers, with the goal of helping other agencies and states replicate the program.

In the meantime, the students and bus drivers of Acton-Boxborough will be enjoying quieter rides without any diesel fumes, said Crosby, the district energy manager.

“We are improving their quality of life immediately, and helping to create a cleaner, more stable future for them,” she said. ​“There’s nothing that matters more to us.”

A safer nuclear fuel is gaining steam — but cost remains a hurdle
Jun 2, 2026

New U.S. regulations and a wave of startup interest are breathing new life into TRISO-fueled reactors, which have struggled to take off due to high fuel costs.

As the U.S. looks to revive its stagnant nuclear industry, a group of companies is racing to realize the promise of a ​“meltdown-proof” fuel that for decades has struggled to progress beyond federal lab experiments.

Tri-structural isotropic fuel, known as TRISO, is safer and more stable than the fuel rods used by the large-scale water-cooled reactors that make up the vast majority of the world’s nuclear power plants. Both fuel sources use enriched uranium, but in TRISO, the element is balled into poppyseed-sized spheres with ceramic coating that can absorb dangerous radioactive materials.

The hitch is the cost: TRISO is orders of magnitude more expensive than conventional assemblies of low-enriched uranium. Given that hefty price tag, only a few TRISO-fueled reactors have ever been built worldwide, even though the technology has existed for years and the world is hungry for nuclear projects that promise to avoid the worst accidents of the past.

But renewed interest is growing as TRISO producers claim they can cut the cost of the fuel by as much as 50% in the coming years, and as a growing number of companies make progress building reactors that can demand that supply.

In mid-May, the U.S. Nuclear Regulatory Commission made history when it advanced a new nuclear plant with a mere monthslong environmental assessment rather than the yearslong environmental impact statement required of every other atomic power station in the country. Regulators said they moved faster in part because the 80-megawatt design from the next-generation developer X-energy relied on TRISO.

But X-energy is not the only developer seeking to use TRISO.

One of the two new nuclear plants currently under construction in the U.S. is a TRISO-based design from Kairos Power. Of the nearly two dozen U.S. startups hawking next-generation reactor designs, at least seven companies are aiming to build fission plants that run on TRISO.

New licensing pathways at the NRC could also give TRISO a boost, as the fuel’s well-documented safety qualities make permits easier to come by for the startups using it.

The momentum comes as public support for nuclear power reaches its highest level in years in the U.S. Some advocates see nuclear energy as a necessary tool to meet surging power demand, while others — particularly blue-state lawmakers and environmental groups that have abandoned anti-nuclearism — view the most reliable carbon-free energy source as a bedrock of a future electrical grid free of fossil fuels.

The 94 operating nuclear reactors in the U.S. are all large-scale models that are cooled by water; most of them were designed and built more than a half century ago. Firms looking to develop reactors that run on TRISO are part of a broader wave of startups that think the best way to build new atomic energy is by pursuing lower-powered small modular reactors, whose designs can be refined and made cheaper through assembly-line repetition.

Companies looking to go the route of microreactors and small modular reactors, however, face not only the challenges that plague large-scale reactors, such as pushback over radioactive waste and costly fuel sources, but new ones, too. For TRISO, those challenges are cost and an immature supply chain — plus the fact that the fuel’s performance remains largely untested at any commercial scale.

Not such a new technology

Research on TRISO began in the late 1950s in the United Kingdom. At the time, British nuclear regulators had started work on the so-called Dragon reactor at a U.K. Atomic Energy Authority site in Dorset, England. Cooled with pure helium, which can absorb three to five times as much heat as water, the high-temperature gas-cooled reactor needed a fuel that could match its heat tolerance. Thus, TRISO was born.

The first attempts to run a reactor on TRISO worked. The British Dragon ran on the fuel, as did similar experimental high-temperature gas-cooled reactors completed in the 1960s, such as Peach Bottom Unit 1 in Pennsylvania, Germany’s Arbeitsgemeinschaft Versuchsreaktor, and Japan’s government-owned high-temperature test reactor.

But the market remained tiny. Of those four midcentury test reactors, just the Japanese unit remains in operation. In Colorado, the Fort St. Vrain nuclear plant, the only American attempt at commercializing a high-temperature gas-cooled reactor running on TRISO, shut down in 1989 after a decade of high maintenance costs and frequent technical troubles.

Right now, the only commercial TRISO-fueled reactor in the world is in China. It came online in 2023 and uses a form of the fuel based on low-enriched uranium, rather than the more potent high-assay low-enriched uranium, or HALEU, that many U.S. firms are eyeing.

The small number of TRISO-fueled reactors has made it hard for fuel companies to dedicate any space or capacity to producing the fuel, and has kept prices high as a result. TRISO costs an estimated $30,000 per kilogram — more than nine times the roughly $3,300 per kilogram for conventional fuel.

These fuel costs can be offset in part by the fact that TRISO designs don’t need to build expensive concrete containment domes. A reactor’s containment dome alone, after all, made up on average about 4% of the total upfront costs for reactors built between 1976 and 1987, according to a 2020 study in the journal Joule. And that doesn’t include the cost of the steel containment vessel that encloses the reactor under the dome. Nor does it account for the fact that, as the study concluded, productivity at recent U.S. plants — likely meaning the infamously budget-busting pair of gigawatt-sized Westinghouse reactors at Southern Company’s Plant Vogtle in Georgia — was 13 times lower than industry expectations.

While there’s no obvious magic number on which the economics hinge, producers agree that the TRISO market will not take off until the fuel is produced at a large enough scale to significantly bring down costs.

X-energy, for its part, owns a TRISO-manufacturing subsidiary to ensure its own fuel supply. It plans to get the facility online by as soon as next year and said it’s using a standard fuel design honed as part of a decades-long DOE program to support research into the fuel.

BWX Technologies, the nuclear fuel giant that generates fuel for the U.S. government, is currently working on a dedicated $500 million plant to manufacture the fuel in Gillette, Wyoming.

If operations begin as expected by 2031, the plant alone would slash the price of TRISO in half, said Erik Nygaard, BWXT’s director of product development. Recent supply contracts from firms including Antares and Kairos have buttressed BWXT’s investment plans for the facility.

“If you’re making hundreds of kilograms a year in a factory that has all this other cost and overhead, and then you go to a dedicated factory that’s completely designed around how you want your process flow, you get to spread your cost over a much, much greater volume,” Nygaard said. ​“It doesn’t take a lot to make the economics work. The problem has just been needing enough demand booked to put the shovel in the ground and build this really big facility.”

A new ​“primary defense mechanism”

TRISO-based designs may be at a disadvantage when it comes to fuel cost and supply — but in the U.S., a series of recent regulatory moves have given this class of reactors a leg up when it comes to permitting.

In March, the NRC made the first major update to its licensing standards since 1956 — the culmination of an effort to speed up nuclear licensing that started with a bipartisan law signed by former President Joe Biden and that has been accelerated under President Donald Trump.

Known as Part 53, the licensing pathway allows developers of next-generation technologies to assess the safety of reactors through a risk-informed analysis. It’s a less prescriptive approach than the traditional pathways, which were written to account for the specific safety concerns that come with building a conventional, large light-water reactor.

That new flexibility could benefit TRISO-based designs. Part 53 offers an open-ended option to prove, for example, that the inherent qualities of a TRISO-based design may make it unnecessary to build an expensive concrete containment dome for a reactor.

“Absolutely, there are substantial safety benefits to using TRISO,” said Jeremy Bowen, the head of the NRC’s newly created Office of Advanced Reactors.

In fact, when the NRC greenlit construction permits for the first two demonstration units Kairos Power is building at its debut plant in Oak Ridge, Tennessee, the agency cited the unique safety of the Google-backed developer’s molten salt-cooled, TRISO-fueled reactors. Those reactors, under construction with a target commissioning date of 2030, are the first TRISO-based reactors underway in the U.S since Fort St. Vrain, which closed 37 years ago.

“We were able to credit the safety of TRISO,” Bowen said of assessing Kairos’ applications.

The combination of the molten salt coolant, which can reach much higher temperatures than water, and the TRISO fuel amount to what the NRC called ​“functional containment design,” meaning a meltdown was so impossible to fathom that a concrete dome over the reactor wasn’t needed.

“Those aspects gave us confidence there was minimal risk of a radiation release and public safety concerns for impacts on the environment,” Bowen said.

The newly proposed Part 57 — another licensing pathway the NRC designed for smaller reactors — also peels back some of the initial safety layers that apply to traditional atomic stations, including both concrete containment domes and miles-wide emergency planning zones.

The NRC created both Part 53 and the proposed Part 57 in large part to speed up permitting processes for smaller nuclear reactors. But these pathways may be viable only for the crop of next-gen nuclear firms that use TRISO in their designs.

To use a licensing pathway such as Part 57, for example, a developer would need to prove that an accident would risk the release of less than 1 rem of radiation, the same amount the human body gets from a CT scan, throughout the duration of the incident.

“TRISO, according to the NRC, is its own containment vessel,” said Adam Stein, the director of nuclear energy innovation at the Breakthrough Institute. ​“It would be difficult for a different fuel source to meet that 1 rem criteria.”

Other firms may be forced to rely on the traditional, slower-moving Part 50. It’s not a death sentence — X-energy opted for that approach for both of its debut power stations — but other developers have complained that Part 50 puts them at a disadvantage in terms of timing, and requires pushing back against measures in the process that were designed for large water-cooled reactors.

The safety features of TRISO are all the more appealing given that many nuclear startups are staffed by people with no prior experience working with reactors, said Paul Dickman, an expert at the American Nuclear Society and the former chief of staff to the NRC chair from 2006 to 2010, the last time the U.S. had planned to embark on a large buildout of new reactors.

Under the new regulatory structures, ​“you’re putting a lot of reliance on the fuel — that’s your primary defense mechanism,” Dickman said.

“This is a bunch of guys who don’t have pilot’s licenses designing airplanes. That isn’t to say their airplane isn’t going to fly, but there’s a lot of things you learn from experience,” he added. ​“To them, it’s all about reinventing everything. That’s a problem.”

But a solution, he said, is turning to a fuel that has inherently safe properties — even if it comes with different challenges in terms of cost and availability.

For his part, Dickman expects the market for TRISO to expand in response to the new regulatory options.

Kurt Terrani, the chief executive of the TRISO manufacturing startup Standard Nuclear, also expects the same.

“They’re not saying you have to use TRISO, but it’s pretty, pretty easy to arrive at the fact that if you really want to meet the limits, it behooves you to use TRISO,” he said.
