Important Aspects of Annual Energy Calculation Techniques for Low Head Hydro Power Plants
Annual energy calculations are frequently used to optimize design parameters at a turbine site and to compare energy production based on equipment offers from various suppliers. In this...
Quantifying Uncertainty in Hydropower Planning
Power system operators must deal with various types of uncertainties. Some are related to inputs, such as system load and water supply, while others pertain to the system itself, such...
Joint Economic Evaluation of Pumped Storage in Colorado
This paper summarizes a joint planning study completed in December 1988 on the economic potential of pumped-storage development. The study was unusual in water development investigations...
Rule Curve Operation at Terzaghi Dam to Pass the Probable Maximum Flood
Terzaghi dam is located on the Bridge River, a tributary of the Fraser River. The spillway was originally designed for the 1000-year flood. Probable Maximum Flood (PMF) studies completed...
