The Event
On February 17, 2026, Ormat Technologies announced a Power Purchase Agreement (PPA) with NV Energy to supply up to 150 MW of new geothermal capacity for Google's data centers in Nevada. Projects are expected to come online between 2028 and 2030, with a contract term of at least 15 years. The deal is structured through the Clean Transition Tariff (CTT) mechanism and awaits Nevada PUC approval in H2 2026.
Why This Is Happening
AI Is Devouring Energy — and the Grid Can't Keep Up
In 2026, hyperscalers (Google, Meta, Microsoft, Amazon) are spending over $600 billion on AI infrastructure. US data center power consumption grew from 23 GW in 2023 to 42 GW in 2025 — with another 296 GW planned. A single AI hyperscaler consumes as much electricity as 100,000 households. Meanwhile, the queue for grid connection is 7 years, and 36 projects worth $162B are blocked or delayed.
The problem isn't money — it's a physical shortage of electricity. Data centers are competing with cities for space on the grid.
Google Committed to 24/7 Carbon-Free Energy by 2030
In 2020, Google set a public goal: by 2030, every hour of electricity consumption across all data centers must be matched with carbon-free energy — not annual offsets, but real-time consumption. Five data centers already operate at 90%+ carbon-free energy (Denmark, Finland, Iowa, Oklahoma, Oregon). But every new AI cluster makes the goal harder.
Why Geothermal Specifically
Solar panels work 20-30% of the time (daytime only, no clouds). Wind is variable. Data centers need baseload — stable 24/7 power. Geothermal is the only clean source with 90%+ capacity factor. Plants run around the clock regardless of weather, with minimal land footprint. According to a Stanford study (Jan 2026), adding just 10% EGS to the energy mix reduces wind needs by 15%, solar by 12%, and battery storage by 28%.
Google recognized this early — investing in geothermal since 2008. In 2023, partner Fervo Energy launched the first enhanced geothermal plant in Nevada (3.5 MW, wells at 8,000 ft, water at 190+ C). In 2024, expansion to 115 MW. The Ormat deal at 150 MW is the next logical step, diversifying suppliers.
How the Deal Works: Clean Transition Tariff
Google doesn't buy power directly from Ormat. Here's the structure:
- Nevada PUC (regulator) approved the Clean Transition Tariff in 2025
- Google pays NV Energy the standard electricity rate + ~20% premium
- NV Energy (utility) uses that premium to sign PPAs with Ormat for new geothermal capacity
- Ormat's energy is earmarked for Google's data centers
Why does Google pay more? Because without the premium, geothermal is more expensive than conventional power and doesn't get built. Google is essentially financing construction of dedicated power plants, getting guaranteed power for AI for 15+ years in return. That's cheaper than scrambling for power in 5 years on an overheated market with a 7-year queue.
Ormat Pivots to Data Centers
In January 2026, Ormat signed its first direct data center PPA — a deal with Switch for ~13 MW. The Google deal at 150 MW is a 10x scale leap, signaling a strategic pivot.
What Happens Next
The Hyperscaler Geothermal Race
According to Rhodium Group, geothermal could meet up to 64% of data center growth by the early 2030s. Meta has already signed a 150 MW deal with Sage Geosystems. Microsoft and Amazon will likely follow — the question is "when" and with whom.
Nevada as a Geothermal Hub
The concentration of deals in Nevada (Fervo, Ormat, Sage) is turning the state into a geothermal energy center for AI. Cluster effect: infrastructure, expertise, and regulatory support attract new players.
Risks
Ormat did not specify whether projects will use conventional or enhanced geothermal technology. EGS is more scalable but less proven. If projects are delayed, the AI infrastructure energy deficit will deepen.
