Evaluation of Duke Energy Carolina and Duke Energy Progress Unit Commitment and Dispatch Practices at its Coal-fired Power Plants in North and South Carolina


Devi Glick provided expert testimony on behalf of Sierra Club in the Fuel Charge Adjustment Proceeding filed by Duke Energy Carolinas (DEC) and Duke Energy Progress (DEP) in North Carolina on behalf of the South Carolina Coastal Conservation League and the Southern Alliance for Clean Energy in South Carolina. Ms. Glick's testimony evaluated Duke’s unit commitment and dispatch practices at its coal-fired power plants. Her testimony demonstrated that the costs used by Duke to make its unit commitment decisions differ from those costs it sought to recover from customers and discusses how that discrepancy is driving uneconomic unit commitment decisions. Ms. Glick calculates excess costs that are passed on to ratepayers as a result and makes recommendations as to how Duke can improve its unit commitment process.
