At times of low electrical demand, excess generation capacity is used to pump water into the upper reservoir. When there is higher demand, water is released back into the lower reservoir through a turbine, generating electricity. Reversible turbine/generator assemblies act as combined pump and turbine generator units (usually Francis turbine designs). Variable speed operation further optimizes th
