NV Energy has added a 484MW combined-cycle plant at its existing 144MW Harry Allen Generating Station in Nevada, US.
The Harry Allen combined-cycle addition consists of two combustion turbine generators, two heat recovery steam generators.
The plant utilizes a dry-cooling system to produce electricity using only 6% of the water required, recycles 75% of the water used and gives out lesser emissions.
The new facility will provide energy to supply approximately 375,000 homes and can meet 80% of the energy needs of southern Nevada.
Work on the new facility began in 2007, with Shaw Group serving as the contractor for engineering procurement and construction services, General Electric, for combustion and steam turbine equipment and Vogt for the heat recovery steam generator.
