The Limerick Generating Station in Pennsylvania is located next to the Schuylkill River in Limerick Township, Montgomery County, northwest of Philadelphia. The facility has two General Electric boiling water reactor (BWR) units, cooled by natural draft cooling towers. When conditions are right, these cooling towers emit enough water vapor to be seen as far away as Centralia in Columbia County.
The two units are capable of producing almost 1,200 megawatts of power each, which combined would provide electricity to over 2 million households. Exelon Corporation owns and operates this facility.
