Exelon to Build Nearly 2,000 MW of Capacity to ERCOT Energy-Only Market

Exelon Generation announced that it is planning on adding nearly 2,000 MW of new generation in ERCOT's energy-only market.

Exelon Generation announced that it is planning to build two combined-cycle gas turbine (CCGT) units in Texas built on existing Exelon sites: one at Colorado Bend Generating Station, currently a 498 MW natural gas plant in Wharton County, TX; and the other at the 704 MW Wolf Hollow natural gas plant in Granbury, TX.

Each new unit will add approximately 1,000 MW of capacity to their respective sites.

Being mindful of increased water efficiency in drought-prone Texas, Exelon said that the new units will be cooled with air instead of water.

Construction of the units is expected to begin in 2015 with commercial operation targeted for 2017.
