  1. Pump Storage:A System Operations Perspective

  2. Pump Storage: A System Operations Perspective • Sam Holeman • Power System Engineer • 25 years at Duke Energy • 7 yrs - Energy Management System Development • Generation Resource Commitment logic • Generation Economic Dispatch logic • Power Flow logic • 18 yrs – Bulk Electric System Operations • NERC Certified System Operator-Reliability • 0 yrs – Pump Storage Asset Operations • 0 yrs – Pump Storage Asset Main

  3. In Light of This….The New Title is…… Pump Storage: The Duct Tape of System Operations

  4. Duke Energy Carolinas Generation Mix • These are approximations • Total Generation Capability – 21,000 MWs • Nuclear – 7000 MWs • Fossil (Coal) – 7600 MWs • Combustion Turbines – 3100 MWs • Conventional Hydro – 1100 MWs • Pump Storage Hydro – 2000 MWs • Pump Storage Hydro (MWs) – approx. 9.5% of capacity • Pump Storage Generation (MWhrs) – approx. 2.5% of energy generated

  5. From the view of System Operations…… Bad Creek Pumped-Storage Generating Station Capacity: 1,065 megawatts Location: Oconee County, South Carolina Commercial Date: 1991 Jocassee Pumped-Storage Generating Station Capacity: 610 megawatts Location: Pickens County, South Carolina Commercial Date: 1973 Numbers don’t tell the story of the value of Pump Storage!

  6. The Pump Storage System Operations Story • NERC Interconnected Operations Services • Operating Reserves • Regulating Reserves/Load Following • Contingency Reserves • Reactive Power Supply • Frequency Response • From the eyes of System Operations • Dependable • Flexible • Fast/ • Nimble • Our Duct Tape

  7. Operating Reserves/Load Following/Regulating Reserves
