Hydroelectric power is an important component of PPL’s renewable energy portfolio.
Our hydro plants in Pennsylvania and Montana are capable of generating 757 megawatts of clean, renewable electricity.
Expansion projects in progress at PPL’s Holtwood hydroelectric plant in Pennsylvania and Rainbow Dam hydroelectric plant in Montana represent a more than $650 million investment in renewable energy. The projects will add a total of 164 megawatts of clean energy and help the environment at the same time. In fact, the new turbine at Rainbow Dam near Great Falls will result in resource benefits to fisheries habitat in the Missouri River. It will have wider flow passages and fewer rotating surfaces, making it easier for fish to pass through unharmed. At Holtwood, the expansion project will result in improved passage for migratory fish along the Susquehanna River and its tributaries.
