In 1966 construction began on the then recently completed Kinzua Dam so that it could generate hydroelectric power. The Seneca Pumped Storage Project, nicknamed "the Seneca Project", is a pumped storage hydropower generation facility on Ohi:yo'. Today 450 megawatts of electricity are produced annually.
The Seneca Pumped Storage Generating Station was owned and operated by the First Energy Corporation until 2013 when New York City's LS Power bought the rights.
