Ultimately, there is room for both batteries and pumped hydro (and for other storage solutions too), and they may even complement each other. Batteries are more cost-effective at delivering small amounts of stored energy over a short time at high power levels. Pumped hydro is more cost-effective at storing and releasing larger amounts of stored
Batteries offer near-instant response time, but cost tends to scale linearly with size, making very large batteries or systems of batteries prohibitively expensive. Mechanical energy storage, in contrast, tends to be inexpensive at large scales due to the use of relatively low-cost materials (e.g., concrete and steel) and low-cost storage media

Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost surplus off-peak electric power is typically used to run the
