The 508MW unit will help meet additional electricity demand growth this year and beyond for SWEPCO customers in Louisiana, Arkansas and Texas.
The Stall Unit was strategically placed at the Arsenal Hill location to support SWEPCO’s electric system and power needs in the region, and to access existing natural gas pipelines and electric transmission lines, the company said.
According to SWEPCO, combined-cycle plants generate electricity more efficiently and consume less fuel per kilowatt-hour of output than conventional gas-fueled generators. The Stall Unit generates electricity with a gas-fueled turbine and recovers exhaust heat from that process to produce additional electricity in a steam turbine.
The company said that as an intermediate load facility, the Stall Unit will provide power that is quickly available as customers’ usage increases or decreases between base load and peak load. The Stall Unit is located on eight acres of company property adjacent to SWEPCO’s Arsenal Hill Power Plant.
