Alphabet Secures 15-Year Solar PPA for 1 GW, 28 TWh to Power Texas Data Centers
Alphabet signed two 15-year power purchase agreements with TotalEnergies to supply 1 GW of solar capacity from the Wichita and Mustang Creek farms, delivering 28 TWh of renewable electricity to its Texas data centers. Construction kicks off in Q2 2026, marking the largest U.S. solar PPA ever for TotalEnergies.
1. PPA Details
Alphabet has finalized two 15-year agreements with TotalEnergies to procure 1 GW of solar capacity, supplying 28 TWh of renewable electricity to its Texas facilities. This transaction represents TotalEnergies’ largest renewable power purchase agreement in the United States.
2. Project Development Timeline
The solar power will be generated from the Wichita and Mustang Creek projects, both slated to begin construction in the second quarter of 2026. The farms are expected to reach commercial operation by early 2027, feeding clean energy directly into the ERCOT grid.
3. Data Center Operational Impact
Securing a long-term fixed-rate power supply helps stabilize energy costs for Google’s Texas data centers and enhances grid reliability during peak demand. The deal reduces exposure to wholesale market price swings and supports uninterrupted AI and cloud services.
4. ESG and Cost Implications
This PPA advances Google’s goal of matching 24/7 energy use with carbon-free sources by 2030 and strengthens its environmental credentials. Locking in solar rates may also yield significant savings versus projected market prices over the 15-year term.
