FervoエナジーとGoogle、396MWの電力購入契約を締結 - 2026年9月1日（火）08:00
専門家の視点
Fervo EnergyとGoogleによる396MWの電力購入契約は、拡張オプション約600MWを含めれば総量約1GWに達する可能性を持つ大型契約です。この契約が地熱発電の商業化において注目すべき点は、2023年に稼働したネバダ州の実証事業からの一貫した発展経路が示されていることです。地熱発電は天候に左右されず24時間稼働できる「確実性」が最大の価値であり、AIデータセンターの電力需要増加という現在のエネルギー課題に対する現実的な解決策といえます。 一方で、この契約は実証段階ではなく商業段階への移行を意味しますが、2028年の稼働予定という時間軸を考慮すると、実際の電力供給までにはまだ数年あります。また、データセンター建設が確定するには工学的実現性や許認可など様々な要因が関わると明記されており、この点が重要な観測点です。 この契約の構造的な特徴は、「無償での追加電力容量の創出」という表現に現れています。既存の料金負担者にコストを転嫁しないという主張は、地熱発電の社会受容性を高めるための重要な物語ですが、実際のコスト構造や地域社会への具体的な利益還元策は記事からは確認できません。
HOUSTON, Sept. 01, 2026 (GLOBE NEWSWIRE) -- Fervo Energy (Nasdaq: FRVO), a global pioneer of next-generation geothermal energy, today announced a 396-megawatt (MW) power purchase agreement (PPA) with Google to enable the continued development of the Cape Station enhanced geothermal systems (EGS) GeoCluster, expected to come online in 2028. Under the agreement, Google will purchase carbon-free energy designed to serve as a foundational building block for a potential data center in Utah. As part of the PPA, Fervo will offer Google an option to expand its offtake by approximately 600 MW, for a total of nearly 1 GW, by June 2030. Final data center plans remain subject to a variety of factors including engineering feasibility, state and local approvals, and commercial conditions. This deal unlocks new, around-the-clock electricity capacity at no cost to existing ratepayers. Fervo and Google are both committed to a responsible growth approach grounded in transparency, two-way dialogue with communities, and sustained local investment. As Google and Fervo’s partnership continues, we commit to upholding these principles in any community where we operate. "This agreement reinforces that EGS is ready to power the next generation of computing infrastructure," said Tim Latimer, CEO and Co-Founder of Fervo Energy. "As demand for reliable electricity grows, customers like Google need energy resources that can be deployed at scale, operate around the clock, and deliver where power is needed. This new PPA is part of our repeatable commercial model that enables us to meet customer needs and directly deliver clean, firm power to large electricity users. We’re proud to do this work in close partnership with the communities of Southwest Utah and with a partner that upholds our community-first values." The Fervo-Google partnership began with Project Red, Fervo’s commercial pilot project in Nevada that came online in 2023. That pilot delivers power to the local grid, including Google's da
