One way round this is to use nighttime electricity to pump water "upstream" and store it in dams, and to then use that water the following day to generate electricity. We can think of the dam as being a humongous storage battery in a way. Some time ago I blogged on another approach suggested by some clever folks in the Netherlands. Their

Read MoreFinally, we assess the overall impact of energy storage market participation on price. It is found that larger energy storage facilities can provoke a great increase in off-peak prices (up to 13.36% for zero risk-aversion operators) and a great decrease in peak prices (up to 7.35%). This effect is mitigated when the storage operator is risk averse.
