Siemens is supplying the main components for the combined cycle plant Keys Energy Center in Maryland, USA to SNC-Lavalin Constructors Inc., who will act as the turnkey EPC contractor for the project. The 735 MW combined cycle plant will be owned and operated by Public Service Enterprise Group. After becoming operational in spring of 2018 the facility will supply power for more than 700,000 households in the suburban Washington, DC, region.
The new natural-gas-fired combined cycle power plant will be erected in in Prince George’s County, Maryland, on a 170 acre site formerly used for a sand and gravel mining operation. Siemens will deliver two SGT6-5000F gas turbines, one SST-5000 steam turbine, two air cooled generators SGen-1000A, and the associated turbine I&C systems.
The SGT6-5000F gas turbine offers economical power generation with fast start-up for peak-, intermediate-, or base-load duty. It achieves peak values for reliability of higher than 99 percent, and continuous operation with highest performance values in its class. With a total of more than 10,000,000 hours of fleet operation, the SGT6-5000F is ideal for use in gas turbine power plants and applications using waste heat including district heating power plants, in combined cycle power plants as well as for integrated gasification (IGCC) applications.
