Lake Michigan water is pumped uphill during periods of low electric demand and stored in a large reservoir. When electricity demand is high, the water is released from the upper reservoir through six pump-turbines for power generation. After passing through the pump-turbines, this water flows back into the lake.
In recent years the electricity system has started to undergo significant changes. Three major developments are underpinning these changes: (i) the rapid digitalization of the energy system leading to smart grids and increasing flexibility in the system; (ii) the increasing electricity generation from variable renewable energy sources, such as wind and solar; and (iii)
