Last updated

Project Thelma · South Haskell County Campus · Homebound Group LLC · Quantum Clean Energy Project (Intersect Power) (formerly tracked as "Google Haskell County Campus (Solar + Storage)")
Under construction

Google's southern Haskell County campus (Homebound Group LLC), paired with the 640 MW/1.3 GWh Quantum Clean Energy solar-and-battery park that Alphabet now owns outright via its $4.75B Intersect Power acquisition. THM1A and THM2A are under active construction toward a projected 440 MW, ~1.4M sq ft five-building campus. Renamed from the tracker's earlier generic 'Solar + Storage' label to Google's own 'Thelma' project designation.
