The story behind this New York power plant
Of New York’s 46 oil-fired power plants, Harris Lake in Newcomb ranks last by electricity produced in 2024, making it the smallest in its category statewide.
This is a standby plant, meaning it exists to be available rather than to run often. It has two generators with a combined capacity (the most power it could supply at one moment) of 4.2 MW, burning distillate fuel oil, a light petroleum fuel. It began operating in 1967 and is owned by NYSEG. Its role is to be ready when called upon.
