Fervo Energy Partners With Nvidia and PNNL on Geothermal Digital Twin

Fervo Energy said Thursday that it began selling electricity from its Cape Station power plant to the grid on September 30, one day ahead of schedule, making it the first enhanced geothermal company to reach a key commercial milestone. The plant synchronized with the grid about a week ago, bringing online the first third of what will soon become a 100-megawatt power plant, while the entire site could eventually generate as much as 4 gigawatts. The first block at Cape Station took 23 months from groundbreaking to commercial operations, and Fervo aims to complete future blocks in as little as 18 months. Google, Southern California Edison, and others have committed to buying power from the project. Fervo went public in May in an upsized IPO that raised $1.9 billion, and as a startup it raised more than $1.3 billion from investors including Breakthrough Energy Ventures, Congruent Ventures, and Capricorn Investment Group.

Controlled Thermal Resources Holdings Inc. and Plum Acquisition Corp. IV announced agreements with strategic investors that are expected to convert approximately $245 million of CTR's outstanding convertible notes into equity and a new planned PIPE structure at the close of their proposed business combination. Under the agreements, roughly $205 million of that convertible debt is expected to convert to equity, while approximately $40 million is expected to convert into the new planned PIPE. The combined company is expected to trade on the Nasdaq under the ticker symbol CTRH, with the transaction targeted to close in the fourth quarter of 2026, subject to shareholder and regulatory approvals. CTR said the simplified capital structure is intended to support project financing for Stage 1 of its Hell's Kitchen development, a planned 50 MW geothermal facility expected to reach commercial operation in 2028, followed by Stage 1 Lithium with planned annual battery grade capacity of 25,000 metric tons targeted for 2030. CTR has invested approximately $310 million in development to date and plans to develop approximately 650 MW of renewable baseload geothermal generation across an approximately 4,000-acre site in southern California's Salton Sea region.

Fervo Energy has reached First Power at its Cape Station project in Utah, with the site now delivering electricity into the grid. The milestone comes alongside fresh U.S. Department of Energy funding and the stock's addition to multiple Russell indices, though shares have fallen 48.6% over 90 days and 54.3% year to date even as they gained 2.2% in one day and 8.2% over 30 days. Fervo trades at $16.71 against an average analyst target of US$40.31, and the most followed narrative pegs fair value at $40.75, or 59% undervalued. That view rests on power purchase agreements totaling 658 megawatts and US$7.2b in contracted revenue, plus a 3 gigawatt framework agreement with Google, set against planned capex of about US$1.2b and ongoing operating losses. A separate check on its P/B ratio of 1.8x, slightly above the 1.6x peer average, suggests a narrower margin of safety.

Fervo Energy announced that its Cape Station geothermal development in Beaver County, Utah, has achieved First Power, the first time a utility-scale enhanced geothermal development has reached that milestone anywhere in the world. The first of three 33-megawatt GeoBlocks in Cape Station Phase I, an approximately 100 MW installation, is now synchronized to the grid and exporting electricity, and is expected to reach its contractual commercial operations date by October 1, 2026, with the remaining two GeoBlocks expected to reach contractual COD by January 1, 2027. The next phase, an additional 400 MW, is already under construction with an expected COD in 2028, and fully contracted offtake at Cape Station sits at approximately 900 MW, enough to power the equivalent of nearly 1 million U.S. homes annually. The milestone comes just over four months after Fervo's May 2026 initial public offering and follows the deployment of its EGS technology at Project Red, which has supplied electricity to the grid since 2023. CEO and Co-Founder Tim Latimer called the achievement a gamechanger for the geothermal industry, while Chief Technology Officer and Co-Founder Jack Norbeck said First Power is proof the science works.

Energy Minister Eknat Prompan has unveiled a major energy restructuring plan, under which the government will reserve 10,000 megawatts of rooftop solar generating capacity specifically for the public, set at roughly 5 kilowatts per household, to spread the right across households nationwide. Under the new approach, the state will buy back surplus power and apply it as a discount on the same billing cycle's electricity bill. A 5-kilowatt system can generate about 600 to 700 units per month, worth roughly 2,000 baht or more, and the state will provide a subsidy of 50,000 baht, with the income from the generated power used to pay it off. The equipment is expected to be fully paid off in about 7 to 10 years. On cutting permitting steps, coordination will be handled solely through the distribution utilities, with a target of about 1 week for inspection and acceptance in self-consumption installations, and no more than 1 month in cases of selling power back. For the new Power Development Plan, or PDP, three goals are set: cleanest, most stable, and fairest. It targets raising the share of clean energy from the current level of just over 20% to close to 50% within 10 years, and no less than 65% in the long term, while reducing reliance on spot-market LNG in favor of long-term contracts, and opening the door to future technologies including hydrogen, geothermal, solid oxide fuel cells, and small modular nuclear reactors, or SMRs. Meanwhile, the public electricity cost that has been embedded in the power tariff structure for 30 to 40 years amounts to a burden of about 18 billion baht per year. The government has removed this burden from the structure and has already implemented a measure capping the first 200 units of household electricity at 3 baht per unit.
