Seneca Station is colocated with the Kinzua Dam, near Warren, Pennsylvania.

The dam was built by the United States Army Corps of Engineers to regulate the Allegheny River as part of a larger flood control project, and, as a secondary role, to generate hydroelectric power.

The station generates on average approximately 570,000 megawatt hours of electric energy every year.

[3] Pumped storage plants function similarly to a storage battery; they absorb excess power generated by such plants in off-peak hours, such as nighttime, using it to pump water into a reservoir.

Like all storage schemes the facility is a net consumer of electricity due to losses in the cycle.
