Any must match electricity production to consumption, both of which vary significantly over time. Energy derived from and varies with the weather on time scales ranging from less than a second to weeks or longer. is less flexible than , meaning it cannot easily match the variations in demand. Thus, without storage presents special challenges to .

The Kyiv Pumped Storage Power Plant (PSPP) (Ukrainian: Ки́ївська гідроакумулювальна електростанція (ГАЕС)) is a pumped-storage power station on the west bank of the Kyiv Reservoir in Vyshhorod, Ukraine. The Kyiv Reservoir serves as the lower reservoir and the upper reservoir is located 70 m (230 ft) above the lower. Water sent from the upper reservoir generates electric.
