New CC units seamlessly tied into existing cogen plant

This article examines how, at Selkirk, two combined-cycle units were added and fully integrated to an existing one. Generating capacity quadrupled, steam output doubled--all without disrupting existing power and steam sales obligations. The Selkirk Phase 2 cogeneration project is a 266-MW natural-gas/distillate-oil-fired combined-cycle (CC) station in Bethlehem, NY, on General Electric Plastics Co.`s (GEP) Selkirk site, near Albany. The project has been expeditiously integrated with its sister plant, Selkirk Phase 1, to provide process steam and power in a highly efficient manner. Selkirk Phase 1, a 93-MW CC cogeneration station was completed in 1992 (POWER, April 1992, p. 169). This facility produces upwards of 400,000 lb/hr of process steam to steam host GEP. Phase 1 power sales are to Niagara Mohawk Power Corp. and Phase-2 sales to Consolidated Edison Co. of New York Inc.
