k. The Project Description:

The Keowee-Toxaway Project consists of two developments: The upstream, 710.1-MW Jocassee Development and the downstream, 157.5-megawatt (MW) Keowee Development owned by Duke Energy Carolinas, LLC. The Jocassee Development includes: A 385-foot-high, 1,800-foot-long main earthfill dam with top elevation at 1,125 feet above mean sea level (msl); two circular intake structures passing water to two water conveyance tunnels leading to four turbines; two saddle dikes (825 feet and 500 feet in length); a partially-open powerhouse just downstream of the dam containing four reversible pump-turbine units authorized for an installed capacity of 177.5 MW each; a 50-foot-wide, concrete, ogee-type spillway with two Taintor gates; a 230-kilovolt (kV) transmission system; and appurtenant facilities. The maximum hydraulic capacity is 36,200 cfs.

The Jocassee Development is operated as a pumped-storage project, with the pump-turbines used for generating power during peak demand periods (typically during the day), and for pumping water back through the tunnels to Lake Jocassee (typically during the night). The pumps have a capacity of 32,720 cfs. The Jocassee Development is also the lower lake for the 1,065 MW Bad Creek Hydroelectric Project No. 2740, which is also owned by Duke, but is not part of this relicensing.

The Keowee Development includes: a 165-foot-high, 3,500-foot-long earthfill dam impounding the Keowee River, and a 165-foot-high, 1,800-foot-long earthfill dam impounding the Little River; four saddle dikes (1,900 feet, 225 feet, 350 feet, and 650 feet in length); an intake dike at the Oconee Nuclear Station; a 176-foot wide, concrete, ogee-type spillway with four Taintor gates; a concrete intake structure leading to two penstocks; a concrete powerhouse at the base of Keowee dam containing two Francis-type, mixed flow turbine-generator units authorized for an installed capacity of 78.8 MW each; a 150-foot by 500-foot concrete tailrace; a 230-kV transmission system; and appurtenant facilities. The maximum hydraulic capacity is 24,920 cfs.

Duke and several stakeholders signed a relicensing agreement (settlement), which resolves all issues to relicensing the project among the signatories.
