A review of pumped hydro energy storage

A risky investment uses a higher discount rate. Almost all the costs of a pumped hydro system are up front, similar to a solar or wind power station, but unlike a gas power station where most of the costs are for fuel. A typical real (after subtracting inflation) discount rate for a low-risk investment is 5%.
