Keystone Generating Station

From Wikipedia, the free encyclopedia

The Keystone Generating Station is a 1,711 MW baseload coal-powered plant located on roughly 1500 acres near Crooked Creek in Shelocta, Pennsylvania.

The facility consists of two steam turbines, which began commercial operation in 1967 and 1968, and four cooling towers.

The main turbines run on steam produced by twin 850 MW boilers, each as tall as a 14-story building. The plant uses in excess of 4 million tons of coal a year. The plant ranks among the best in the US in terms of availability among coal plants of the same size.

Since the plant's initial commissioning, several environmental control systems have either been upgraded or installed. These include modifications to the electrostatic precipitators, the addition of an ammonia flue gas conditioning system to improve precipitator performance, and a low/NOx burner system to reduce the oxides of nitrogen (NOx) emissions. A Selective Catalytic Reactor (SCR) has been installed which further reduces the NOx emissions. The plant has a continuous emissions monitoring system in the stack which must adhere to very rigid accuracy and reliability requirements established by the Commonwealth of Pennsylvania.

A consortium of mid-atlantic power companies owns the plant. PSEG Fossil owns a 22.84 percent share (391 net MW with peaker), while Reliant Resources, operates it. The plant is basically a twin of the Conemaugh Generating Station, also partially owned by PSEG Fossil.
