Winooski One Hydro Plant

Winooski One is a 7.4 Mw hydroelectric generating station located in Winooski, Vermont, on the Winooski River as it flows between the cities of Burlington and Winooski. The station consists of a refurbished spillway with a rubber dam abutting a historic timber crib dam. A fish lift and riverside park have been constructed as part of the station.

The flow of the Winooski River is directed into a powerhouse with three identical double-regulated Kaplan turbines, which drive synchronous generators, allowing for a highly efficient run-of-river operation.

The average annual net output of 30 million kWh is fed directly into BED’s distribution system.

Hydroelectric power is a clean, renewable energy source.
