CHESTER OPERATIONS, a 67 MW Coal power plant in Delaware County, Pennsylvania. Operated by KIMBERLY-CLARK CORP, commissioned 2020.

How CHESTER OPERATIONS compares

With 67 MW of capacity, CHESTER OPERATIONS ranks 61st among the 170 operating power plants Bywatts maps in Pennsylvania and 17th of the 20 operating Coal plants in the state. It accounts for about 0.6% of Pennsylvania's operating Coal capacity and 0.2% of all operating capacity in the state. Nationally it is the 255th-largest of the 324 operating Coal plants in the database. Commissioned in 2020, it is newer than 99% of the 168 operating Pennsylvania plants with a recorded commissioning year. It shares Delaware County with 4 other operating plants, including EDDYSTONE GENERATING STATION and FPL ENERGY MARCUS HOOK LP.

Under the same EIA plant code, EIA-860 lists 4 generators at the site with 69 MW of nameplate capacity. Net generation was 172 GWh in 2024 (a 28% capacity factor), down 9% from 2022.
