SWEPCO Uses What's on Hand

摘要

With the summer heat straining their installed capacity in the southeast region of the United States and forcing out-of-market energy purchases, Southwestern Electric Power Co. (SWEPCO), a unit of American Electric Power, saw a need to bring additional capacity online. Using existing natural gas pipelines and electric transmission lines, SWEPCO in 2006 made plans to build the 523 MW J. Lamar Stall gas-fired combined-cycle unit adjacent to the oldest plant in the SWEPCO system, the Arsenal Hill Power Plant in Shreveport, La. Along with the established pipeline and transmission infrastructure, SWEPCO also owned two Siemens-Westing-house 501FD2 gas turbines, a GE D-ll reheat condensing steam turbine and a modified Thermal Engineering International condenser.
