Hydroelectricity is a particularly important component of PPL’s renewable energy portfolio. PPL hydro plants in Pennsylvania, Maine and Montana are capable of generating 947 megawatts of clean, renewable electricity.
In addition to generating power, these plants provide flood control, irrigation and public recreation, and help protect and enhance fisheries, wildlife, wetlands habitat and water quality.
Renewable hyrdoelectric experience includes:
 Holtwood
A 10-unit hydroelectric facility near the Susquehanna River, about 15 miles south of Lancaster, Pa., Holtwood has a total capacity of 109 megawatts. Currently, PPL is proposing to double the plant’s capacity.
- Safe Harbor
Also on the Susquehanna River, south of Lancaster, Pa. The Safe Harbor plant’s units generate about 420 megawatts. PPL owns one-third of this facility.
- Lake Wallenpaupack
A popular outdoor recreation destination in the Pocono Mountains of Pennsylvania, Lake Wallenpaupack plays a critical role in regional water management. The Wallenpaupack hydroelectric plant, in operation since 1946, includes a dam with a reservoir and a powerhouse with two units and total capacity of 44 megawatts.
- PPL Maine
In Maine, PPL’s hydroelectric operation consists of eight operating projects with about 44 megawatts of generating capacity. PPL recently reached a historic agreement with the Penobscot Indian Nation to reopen 500 miles of the Penobscot River in Maine, helping to save the Atlantic salmon and increasing clean, renewable power at the same time.
- PPL Montana
In Montana, PPL’s hydroelectric operations consist of 11 hydroelectric projects that have a total generating capacity of 604 megawatts, as well as one reservoir. The facilities are located on the Clark Fork, Flathead, Madison and Missouri rivers and on West Rosebud Creek.
