On gas and nuclear in Iran, Ormat, and ammonia

Current conditions: The heat dome in the Southwest is so widespread that 70 million people are experiencing temperatures that bump up against records for this time of year • A Hawaii-linked atmospheric river known as the Pineapple Express is poised to deluge the Pacific Northwest with rain • A moderate geomagnetic storm alert is in effect due to coronal mass ejections, bursts of plasma and magnetic fields from the Sun that cause disruptions to satellites, radio signals, and GPS.

Once again, war has come uncomfortably close to a civilian nuclear power station. But on Wednesday, the International Atomic Energy Agency warned that a missile landed roughly three football fields away from Iran’s Bushehr Nuclear Power Plant. Located on a peninula jutting into the Perisan Gulf, the single-unit station — built with a Russian reactor that came online south of Tehran in 2013 — is Iran's first and only active nuclear station. “Although there was no damage to the reactor itself nor injuries to staff, any attack at or near nuclear power plants violates the seven indispensable pillars related to ensuring nuclear safety and security during an armed conflict and should never take place,” Rafael Mariano Grossi, the IAEA’s director general, said in a statement. The Zaporizhzhia nuclear plant in eastern Ukraine similarly became a scene of intense combat during the early days of the Russian invasion. Grossi visited the front lines at the time and helped oversee the safe shutdown of Europe’s largest nuclear power plant. It’s sitting idle today, still under Russian occupation.
The price of oil and natural gas, meanwhile, soared on Thursday as Iran launched drone attacks on energy facilities in Kuwait, Saudi Arabia, and the United Arab Emirates. President Donald Trump said Wednesday night that he had warned Israel to end attacks on Iran’s South Pars gas field. But if Tehran “unwisely” decided to attack Qatar, the U.S. will “massively blow up the entirety of the South Pars Gas Field at a moment of strength and power that Iran has never seen or witnessed before.” In a post on X, Emma Ashford, a senior fellow at the Stimson Center, warned: “We’re now getting into the tail-end scenarios that usually only merit a sentence at the end of a paper, they’re so unlikely and disastrous.”
In January, Canada reversed years of trade policies to protect its shared automotive industry with the United States from fast-rising Chinese competitors, slashing tariffs to start phasing in imports. To start, Politico reported, Chinese companies can import 49,000 vehicles each year at a tariff rate of 6%. Over five years, annual imports could grow to 70,000 vehicles. At least three Chinese automakers are laying the groundwork to enter the Canadian market as soon as this year, according to an Automotive News report this month citing an advisory firm brokering discussions between Chinese manufacturers and Canadian car dealers.
Chinese electric vehicles are booming across the world in part due to the enormous scale at which the companies can deploy their technologies. “BYD is really a great example of that. They invest so much in R&D that it’s really hard to compete with them on some of these things,” Ilaria Mazzocco, the deputy director and senior fellow with the Trustee Chair in Chinese Business and Economics at the Center for Strategic and International Studies, told Heatmap’s Robinson Meyer on an episode of Shift Key in December.
Ormat Technologies is, to put it in the parlance of today’s youth, the “unc” of geothermal, a seasoned player that’s been around for far longer than the upstarts but has found ways to vibe with the new entrants to its industry. But as interest heats up (forgive the pun) in geothermal, the Nevada-based subsidiary of an Israeli company is raising money to invest in an expansion. On Wednesday, the company pulled in $875 million in its latest fundraise as investors piled onto what was originally announced as a $750 million transaction. While much of the hype around geothermal has focused on next-generation companies that promise to expand the reach of the energy source by tapping into dry hot rocks, conventional resources — underground hydrothermal reservoirs that can be drilled into — are generating more excitement as investors look to deploy new sources of clean power as quickly as possible to meet surging electricity demand. (Read the 101 explainer Heatmap’s Matthew Zeitlin wrote on different forms of geothermal power last year.) “Rather than being treated purely as a niche renewable segment, geothermal is increasingly positioned as: A source of firm, dispatchable power, a complement to variable renewables, and a potential solution for growing electricity demand, including from data centers,” Alexander Richter, the founder of the geothermal trade publication ThinkGeoEnergy, wrote on Wednesday. “At the same time, the Ormat transaction highlights that capital is flowing first to de-risked, scalable platforms, rather than uniformly across the sector.”
That doesn’t mean the darling of next-generation geothermal, Houston-based Fervo Energy, isn’t still the industry’s big magnet for investment. On Thursday, the company announced the close of a $421 million round of non-recourse debt financing to fund the first phase of its flagship Cape Station power plant. Non-recourse financing is a deal structure in which lenders rely entirely upon cash flow from the project to pay back the money used to build it, shielding investors from liability if something goes wrong. “Non-recourse financing has historically been considered out of reach for first-of-a-kind projects,” David Ulrey, Fervo Energy’s chief financial officer, said in a statement. “Cape Station disrupts that narrative.” The project in Beaver County, Utah, is set to deliver its first power to the grid later this year, and reach 100 megawatts of operating capacity in early 2027.

Oklahoma Senator Markwayne Mullin, the Republican President Donald Trump nominated to lead the Department of Homeland Security, said he would “absolutely” repeal a policy the agency’s outgoing chief, Kristi Noem, adopted to throttle the Federal Emergency Management Agency. Since June, Noem has required that her office approve any contracts or grants of $100,000 or over, creating what The New York Times called “significant delays and uncertainty for disaster-struck states and communities waiting for recovery assistance.” The policy delayed FEMA projects by at least three weeks, according to an investigation Senate Democrats released this month. “That’s called micromanaging,” Mullin said at a confirmation hearing on Capitol Hill. “I’m not a micromanager.”
What will become of all the gas turbines deployed today if ever there is a meaningful penalty in our economy for emitting planet-heating pollution? For a long time, developers have promised to eventually swap fossil gas for green hydrogen, which remains expensive today. But many models require at least some hardware tweaks to switch between fuels. That’s what makes this latest news from U.S. energy giant GE Vernova and the Japanese firm IHI so interesting. The two companies announced the world’s first successful demonstration of 100% ammonia combustion in an industrial-scale F-class gas turbine. Low-free ammonia can be produced by combining green hydrogen with nitrogen. Hydrogen Insight reported that GE and IHI plan to deploy the technology commercially by 2030.
Tidal power is geographically limited. But unlike other sources of renewable power, it’s predictable and could, proponents say, play a role in balancing the grid. In the Faroe Islands, the tidal energy developer Minesto has started pumping electricity from its 100-kilowatt microgrid-scale power generation onto the Faroese grid. The Swedish firm told Offshore Energy operations will continue through spring and summer in the autonomous Danish island territory.

On green steel, Europe’s gas problem, and America’s withering onshore wind
Current conditions: Drenching storms are heading for the East Coast tonight, especially in the South • The storms barreling through the Pacific, including the now-Category 4 Hurricane Lowell, are unlikely to make landfall or do much beyond stir up the surf in parts of Hawaii and California • Further west across the ocean, Typhoon Krovanh is hammering Japan’s Amami Islands with rain.
The breakneck speed of China’s deployments of solar panels, wind turbines, and nuclear reactors has done much to curb its emissions, even as the People’s Republic remains heavily reliant on coal. But Beijing’s effort to weather the shock of losing steady access to oil and gas out of the Persian Gulf is paying off as the country accelerates its transition away from hydrocarbons to alternative fuels and electrification. Last month, I told you when Sinopec’s chief executive predicted that China’s demand for oil had already peaked. Now a new report shows that China’s emissions dropped by 1% in the second quarter of 2026 as a result of plummeting oil consumption amid the Strait of Hormuz crisis. Analysis from the Centre for Research on Energy and Clean Air, a Helsinki-based research nonprofit that tracks China’s energy transition, produced for Carbon Brief found that China’s total carbon dioxide emissions fell despite a rebound in coal-fired power generation because oil dropped by 9% overall and by a whopping 16% for transportation. It’s the first time a reduction in oil consumption was directly responsible for falling emissions in China. And the country is likely to see further emissions drops. After all, Chinese technology essentially “saved the world from Trump’s energy crisis,” as my colleague Robinson Meyer teased out in a recent Shift Key episode.

Thanks to the Trump administration’s recent wrangling, the $500 million the Biden administration had given steelmaker Cleveland-Cliffs to upgrade its facility in Ohio to produce steel with a cleaner, electricity-based method is now going to refurbishing the coal-fired blast furnaces at the facility, instead. That made Hyundai’s plans for a hydrogen-powered steel plant in southern Louisiana the flagship green steel project in the nation. Later today, it’s finally breaking ground. Canary Media reported that the South Korean automotive and industrial giant will hold a ceremony Friday to mark the start of construction on the project, which is set to come online by 2029. At first, the project is set to run on hydrogen made from natural gas. But by the early 2030s, Hyundai has laid plans to switch to hydrogen made by electrolysis using clean electricity and produced locally.
Meanwhile, Posco, one of South Korea’s dedicated steel giants, is experimenting with hydrogen-based steel production using iron ore from Australia, the latest sign that the East Asian nation is leaning into green H2, according to Hydrogen Insight.
In 2021, western Europe suffered what the Germans call a dunkelflaute, or “dark doldrums,” when expected wind simply doesn’t blow. As a result, wind turbines produced less electricity, and Europeans tapped natural gas stores to generate power, draining supplies ahead of winter. That left the European Union particularly vulnerable to energy shocks when Russia invaded Ukraine the following February. Once again we find ourselves in a situation where America’s spy chief is going to Moscow to reportedly dissuade the Kremlin from launching an attack on a Western ally and Europe’s gas stocks are way down. On Thursday, the head of the industry group Gas Infrastructure Europe told the Financial Times that natural gas stores are at a record low for this time of year. “If we are faced with a compound shock, this is going to be problematic,” said Lucie Boost, the head of the trade association.
Meanwhile, Russia’s ballooning gas crisis, brought on by Ukrainian attacks on refineries, is hurting another American ally. Mongolia, the splotch of democratic blue in the middle of authoritarian red Asia on the Freedom House Index map, is heavily dependent on Russia for fuel and energy. Fuel prices have nearly doubled since the spring, Reuters reported. In the U.S., diesel prices reached an all-time high on Thursday of $5.82 per gallon, surpassing by a 10th of a cent the previous high set in June 2022. “My routine now starts with checking the overnight wires to see if there were any drone strikes on refineries,” Gulf Oil energy advisor Tom Kloza told my colleague Matthew Zeitlin. “That’s what this business has come down to.”

The U.S. added nearly 5 gigawatts of onshore wind turbines in the second quarter of 2026, but the projects in the pipeline are dwindling by 4%, according to a new American Clean Power Association report. At least 44 gigawatts are “stuck” in the Department of Defense’s review process, though a judge recently ordered the Trump administration to restart processing applications after a prolonged pause. “Time will tell how the Department of Defense reacts to that judgment, and whether or not they start to process those wind projects in the same way that we saw them do before a lot of these actions were implemented,” John Hensley, senior vice president of markets and policy analysis at ACP, told Utility Dive. “If that is the case, then I think there is a large volume of projects sitting behind that bottleneck.”
India’s solar sector has boomed in recent years, especially as the U.S. and Europe went looking for alternate suppliers to China. While the country still has a way to go to build out its capacity for upstream components such as cells and wafers, India’s module manufacturing output has reached 233 gigawatts, with factories operating at most 45% of the time as demand fails to match the maximum potential output, PV Tech reported.
California’s biggest experiment in virtual power plants is progressing. Pacific Gas & Electric announced a first-of-its-kind VPP deal with Google, Tesla, Sunrun, and others coordinating networks of solar panels, batteries, and smart devices in the Bay Area. “This is about delivering power at the speed our economy demands—while improving affordability and reliability for the people we serve,” Chelle Izzi, PG&E’s chief commercial officer, said in a statement.
The August Electricity Price Hub data is in.
It’s another hot and expensive summer.
Across the country, average household electricity bills are up 2.7% in the first eight months of the year, according to the latest update to Heatmap and MIT’s Electricity Price Hub, tacking on $4 per month to the typical bill. This level of rise is consistent with the pace set in 2024 and 2025, but faster than 2021 and 2023.
As we’ve discussed before, some of the fastest growth in prices comes either in the Atlantic Seaboard — with Washington, D.C., Virginia, and New Jersey all having year over year growth rates of at least 7.5% — thanks largely to increased demand and capacity payments in the PJM Interconnection marketplace. Another standout so far this year is Hawaii, which is uniquely dependent on imported oil to power its grid and has seen its 12-month trailing average prices rise by over 8% so far this year.
California, which is well known for seeing especially sharp price increases in recent years largely due to wildfire-related costs, has seen somewhat restrained bill growth so far this year across the state, with the 12-month-rolling average bill rising just 3% in the past 12 months and prices going up 4%. (That price level is still quite high, however, at almost 32 cents per kilowatt-hour, compared to a national average of around 19.)
Rates charged by Southern California Edison, one of the state’s big three investor-owned utilities, are up almost 15% in the past year, averaged across its baseline regions. The MIT researchers attribute this increase to two major factors: one, a decrease in the California Climate Credit, which is paid out to electricity customers from the state’s emissions cap-and-invest program. This year, the credit for Southern California Edison ratepayers is $72, applied to bills in July and August in tranches of $36. Last year, by contrast, Southern California Edison handed out $112 in two tranches, April and October.
The second factor in Southern California Edison’s inflated bills is an increase in the fixed charge portion of the bills ratepayers receive. Following changes in California state law designed to distribute the cost of the grid more equitably, SCE revamped its rate structure at the end of last year to include a “Base Services Charge” of $24 per month for customers not enrolled in any special rate program. At the same time, SCE instituted a roughly 10% decrease in its per-kilowatt-hour electricity rate in order to protect lower-income ratepayers (who would pay a fixed charge substantially lower than the baseline $24). PG&E moved to a similar system earlier this year.
When it introduced the new rates in November of last year, SCE said that “medium energy users” would likely see little change in their bills. Price Hub data suggests, however, that the typical household has seen a bill increase from the new service charge of 13%, even before accounting for the smaller climate credit.
A new policy proposal argues that large load tariffs on their own aren’t enough.
Earlier this year, I attempted to draw up a web diagram about energy affordability. My head was spinning from reading social media threads of experts arguing over the reasons electricity rates were so high, the best strategies to lower them, and how the data center explosion fit into the picture. I wanted to see all of the ideas laid out in one place. Here’s what I sketched out at the time:

That was in March. Looking back at it now, a few things stand out. Of course, Washington hasn't gotten anywhere meaningful yet on permitting reform. Also, the BYOP, or “bring your own power,” idea has in some cases become a justification to build huge off-grid natural gas power plants. Amazon, for example, defended backing what may become the largest fossil fuel plant in the country by saying that it “believes in paying the full costs of powering our operations,” and that the Texas data center project is “powered by new on-site generation that won’t raise electricity costs for Texas families.”
On the other hand, there have been some promising developments in deploying virtual power plants and “grid edge” technologies like rooftop solar, to the benefit of both tech companies and regular folks. In July, New Jersey passed a law to incentivize data center developers to fund virtual power plants that can create more capacity on the grid. The program could ultimately help residential customers get solar panels and batteries, which would bring down their energy bills. Just today, Google announced a partnership with the California utility PG&E to offer residential customers discounts on heat pumps combined with battery energy storage in Alameda and Santa Clara counties. The first 25 homeowners to sign up will get $10,000 off; after that the discount is $5,000.

One strategy I didn’t jot down back in March was the “large load tariff.” This is when utility regulators create a new electricity rate class for large energy users that helps isolate the costs of serving these customers. A growing number of states have gone one step further and developed data center-specific tariffs, with requirements like charging data centers a minimum fee regardless of how much energy they use, and, in some cases, creating incentives for them to build new renewable energy projects.
A policy paper that came across my desk this week argues that this approach doesn’t go far enough. It says that states have an opportunity to fund the modernization of the electric grid by adding a surcharge on top of large load tariffs.
The paper is from the State Support Center, a nonprofit that provides clean energy policy recommendations and technical assistance to states. It was co-founded by Sam Ricketts, one of the founders of the climate group Evergreen Action and a significant voice in shaping the Inflation Reduction Act. Initially, the Center helped states figure out how to take advantage of all of the new federal funding that came out of that law. Now, like the rest of us, Ricketts is thinking about data centers.
“State policymakers are looking for ways to meet the load growth that is predominantly being driven by data centers,” he told me. “There hasn't been a thorough-enough discussion about capturing investments that large data center loads are making and using those revenues to drive investment into key barriers for the clean grid expansion that the electricity system in the U.S. now needs.”
Traditional large load tariffs are about cost assignment, Ricketts said: Regulators determine the cost of network and operational upgrades required to serve big customers and require utilities to pass those on directly rather than spreading them across the entire customer base. This is just the baseline of what data center developers should do to pay their “fair share,” though, Ricketts argued. Even if large load tariffs help cover the cost of new power plants, they don’t necessarily help solve the interconnection bottlenecks that are preventing generators — especially renewables — from joining the grid, for example.
By adding a simple per-megawatt surcharge to the rates data centers pay, states could raise revenue to accelerate interconnection. They could fund additional staff and invest in new software solutions to help move through the queue of projects waiting to connect faster. They could also put the money toward financing grid upgrades, such as installing grid-enhancing technologies that create more capacity on existing power lines. Alternatively, they could use the money to reward cities and towns for permitting projects more quickly, or to support siting and permitting at the state level, the paper suggests.
Ricketts told me that many state utility commissions have the power to do this today, and those that don’t would require just a simple bit of legislation to empower them. New York could become the first to adopt the idea. In June, Governor Kathy Hochul directed the state’s Department of Public Service to consider requiring data centers to invest in a “grid acceleration fund.”
Several states have already levied similar fees on data centers — they just haven’t dedicated the money toward grid upgrades. A new $0.01-per-kilowatt-hour surcharge on loads larger than 100 megawatts in Oregon will fund efficiency and distributed energy projects that reduce costs for residential customers. Virginia enacted a $0.011 per kilowatt-hour data center electricity consumption tax that will raise money for the state’s general fund. It’s expected to generate $600 million per year.
The paper doesn’t pitch the surcharge as a cure-all, nor does it touch the issue of public opposition or federal permitting obstacles. “The surcharge as envisioned and proposed here is pretty modest,” Ricketts told me. “It is trying to attend to a gap, which is like, hey, there's an opportunity here to capture reinvestment into the grid needs that are truly necessary.”
