Oil and gas major TotalEnergies has started operations on two solar-plus-storage projects in the ERCOT, Texas market, one with the BESS online and another set to be commissioned next year.

The projects are the 720MW Danish Fields project, which is TotalEnergies’ largest solar farm in the US, and the 455MW Cottonwood project.

Both projects feature a 225MWh battery energy storage system (BESS), provided by TotalEnergies subsidy Saft, with the Danish Fields BESS currently in operation and the Cottonwood BESS set for commissioning in 2025.

TotalEnergies has also signed power purchase agreements (PPAs) to sell power generated at both projects. At Danish Fields, 70% of the project’s output will be sold to what TotalEnergies called “industry players”, including construction materials manufacturer Saint-Gobain, while the remainder will be used to decarbonise TotalEnergies’ industrial facilities in Texas and Louisana. Meanwhile, the PPAs signed at the Cottonwood project, also with Saint-Gobain, are indexed with merchant prices to “support their decarbonisation efforts”.
