Pumped hydro makes up 152 GW or 96% of worldwide energy storage capacity operating today. Of the remaining 4% of capacity, the largest technology shares are molten salt (33%) and lithium-ion batteries (25%). Flywheels and Compressed Air Energy Storage also make up a large part of the market.
Subsequently, the energy storage system is configured according to user energy consumption patterns, PV power generation, and time-of-use pricing rules. The energy storage system, as a load-shifting device, plays a role in mitigating the intermittency of photovoltaic generation and taking advantage of time-of-use pricing opportunities.
