About the 1.2 GW Power Project

The plant will be developed and owned by a SLEC subsidiary and will operate within the Electric Reliability Council of Texas (“ERCOT”). This combined cycle power station will consist of two Siemens Energy SGT6-9000HL gas turbines, among the most technologically advanced turbines in the world, featuring high power output, excellent fuel efficiency, and the capability to operate on hydrogen with only minor modifications to the equipment. These turbines can provide reliable power generation to the region while supporting decarbonization goals. The combined cycle power station will be located near a 24-inch tap off the Matterhorn Natural Gas Pipeline.
