The Blenheim–Gilboa Pumped Storage Power Station is a pumped-storage hydroelectricity plant in the Catskill Mountains of New York State. The plant is part of the New York Power Authority, and can generate over Script error: No such module "convert". of electricity. It is used daily to cover peak demand. There are two reservoirs that are involved in the project, both with a capacity of Script error: No such module "convert".; one at the foot of Brown Mountain in the Schoharie Valley, and another one at the top of the mountain. The power station has an accumulated capacity of about Script error: No such module "convert". after storing up to Script error: No such module "convert"..[1]
The reservoir at the foot of the mountain (Script error: No such module "Coordinates".) was created by impounding the Schoharie Creek downstream from the village of Gilboa, New York. Water from this reservoir is sent through a concrete shaft up the mountain to the upper reservoir (Script error: No such module "Coordinates".) to be stored until it is needed. When power is needed, the water is sent back down the mountain into the lower reservoir, where it enters a power plant on the banks of the lower reservoir, and spins a series of turbines in the powerhouse. (This structure is almost completely underwater; only five feet of it can be seen above water when the reservoir is full). The water is sent back into the reservoir, flows over the dam that holds the reservoir back, and continues down the rest of the Schoharie Creek. The powerhouse, built in 1973, contained four Hitachi Script error: No such module "convert". pump/turbine units. The gross head range on the units is Script error: No such module "convert".. Between 2003 and 2010, the turbines were upgraded so that each generator/motor operates at up to approximately 318 MVA at 0.9 power factor pumping power, or Script error: No such module "convert". as a generator. Additionally, the old 285 MVA generator step up transformers were replaced with new 17kV/345kV, 325 MVA transformers. Overall plant cycle efficiency is 73%.[2]
Blenheim–Gilboa Visitors Center
The Blenheim-Gilboa Visitor Center is housed in a restored 18th century dairy barn, and features exhibits and interactive displays that demonstrate the science of energy and electricity, including how power is made and used. Admission to the center is free. The historic Lansing Manor House is a historic house museum adjacent to the Visitor Center. The Visitor Center, Lansing Manor House and the Power Project are located near Mine Kill State Park.
