A pumped hydroelectric storage reservoir has an area of 0.5 km2 and an average depth of 10m. The water flows to a lower reservoir with a head of 200m. a) What is the total energy available in MWhe? Assume a generator efficiency of 83%. b) If SCSU requires an average of 350 MWe to fulfill its needs, how long will the stored energy from the pumped hydroelectric facility last.
