Project Tembo

Project Tembo (formerly Cheyenne AI Factory / Project Jade) is a 2.7 GW behind-the-meter power generation and carbon capture project supporting Google's data center campus at the Switchgrass Industrial Park in Cheyenne, Wyoming. It is developed by Tallgrass Energy, through subsidiary BFC Power LLC, with Google as the underlying customer via Jupiter Star Holdings LLC. Google announced the project on November 6, 2026, as a $17 billion long-term commitment — its first data center campus in Wyoming. Phase 1 will deploy 702 MW of Bloom Energy solid-oxide fuel cells (SOFC), the largest planned fuel-cell power development for a data center to date, under a $2.65 billion equipment agreement announced January 8, 2026. American Electric Power (AEP) holds a 20-year power offtake and will operate the generation facility. Commercial operations are targeted for late 2028, expandable to 2.7 GW by 2031 and scalable to 10 GW. The SOFC exhaust stream contains CO₂ at roughly 12 times the concentration of combustion flue gas, making capture substantially more economical than from conventional gas-fired generation. Captured CO₂ will move via Tallgrass's Trailblazer CO₂ pipeline to the Eastern Wyoming Sequestration Hub for permanent storage. Google, Black Hills Energy, and Tallgrass are also conducting FEED studies on retrofitting carbon capture onto nearby combined-cycle gas turbines. The fuel cells are hydrogen-ready, allowing future conversion to hydrogen or hydrogen blends without hardware replacement. The facility is air-cooled, avoiding strain on municipal and groundwater supplies. Google has committed to covering 100% of the data center's direct power consumption and grid upgrade costs.
