The New York Power Authority plans to rehabilitate four 33-year-old pump-turbines, motor-generators, and possibly other components at the 1,040-MW Blenheim Gilboa hydro project (No. 2685), adding 120 MW of capacity to the U.S. plant.
NYPA plans to install new high efficiency turbine runners and to modify stay vanes, wicket gates, and seal systems. The upgrades are expected to increase project capacity by 11.5 percent.
Blenheim Gilboa, on Schoharie Creek in Schoharie County, is one of two pumped-storage projects in New York. It began operation in 1973 and generates about 1,500 gigawatt-hours annually.
Plans call for dewatering the project’s upper reservoir in the fall of 2006 as part of the authority’s life extension and modernization program.
The plan requires the approval of the Federal Energy Regulatory Commission. In an application to amend its FERC license, NYPA said the proposed modifications would increase generating efficiency, increase resistance to cavitation erosion, and enhance the flexibility of the plant to meet peak demand. FERC issued notice of the application Jan. 25.
