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%.
Pumped storage: powering a sustainable future
Batteries are more cost-effective at delivering small amounts of stored energy over a short time at high power levels. Pumped storage has more complex site-selection constraints and takes longer than battery energy storage systems (BESS) to move through planning, design and construction; however, once operational, the pumped …
