Hyperscalers are scouring the U.S. power grid as the exponential expansion of AI data centers collides head-on with corporate carbon neutrality targets. For years, Google leaned heavily on wind, solar, and battery storage to chase its 2030 net-zero goals. That clean-energy playbook hit hard physical realities this April, however, when the search giant contracted 933 megawatts of natural gas generation from Crusoe in Texas simply to keep its compute infrastructure from stalling out.
Contracting Baseload at Cape Station
To power an upcoming data center cluster in Utah without completely abandoning its climate commitments, Google signed a direct power purchase agreement (PPA) for 396 megawatts from Fervo Energy's Cape Station geothermal facility. Slated to come online in 2028, the deal includes an option running through June 2030 to secure an additional 600 megawatts, effectively locking in up to 1 gigawatt of dedicated, firm capacity. Unlike intermittent solar and wind, enhanced geothermal systems (EGS) deliver the continuous, 24/7 baseload that multi-gigawatt AI training clusters demand.
Sarah Jewett, senior vice president of strategy at Fervo, told TechCrunch in May that a third-party engineer said the site holds enough heat to generate twice as much electricity as its permitted 2 gigawatts.
Fervo currently holds permits for 2 gigawatts at Cape Station. If the reservoir yields the 4 gigawatts projected by third-party engineering assessments, that single asset would roughly double total installed U.S. geothermal capacity, according to Department of Energy data. Across the wider grid, the agency estimates advanced geothermal techniques could eventually tap up to 57 terawatts of deep thermal energy.
Capital Commitments and Generation Realities
This long-term PPA deepens a five-year relationship between Google and Fervo, stretching from pilot-stage power purchases to Google taking equity in Fervo's final private round before its public debut. Following the announcement, Fervo shares surged 30% before settling. Beyond the market reaction, the structural takeaway for enterprise leaders is clear: off-grid and novel baseload contracting is shifting early-stage energy development capex directly onto Big Tech balance sheets. Locking in long-term power tariffs now is rapidly becoming the only defense against an imminent transmission bottleneck and grid capacity crunch.
Securing next-generation geothermal capacity allows hyperscalers to defend their clean-energy branding on paper. Yet until advanced geothermal scales to commercial maturity at Cape Station in 2028, the industry's near-term compute reality remains anchored to bridge contracts like 933 megawatts of Texas gas.
