Ranking of total installed capacity of energy storage

Which countries have the most grid-scale battery energy storage systems in 2023?

This treemap, created in partnership with the National Public Utilities Council, visualizes which countries had the most grid-scale battery energy storage systems (BESS) in 2023. China has nearly half the world’s grid storage battery capacity and keeps growing at a breakneck pace.

What is the total global energy storage capacity?

As of 2018, the global energy storage capacity is 8 GWh. This capacity is continuing to increase at an exponential rate, with pumped hydro storage accounting for 96.2% of the worldwide storage capacity.

Which utility company has the most energy storage capacity?

NextEra Energy NEE is the utility provider with the most energy storage capacity in the United States, with more than 150 MW of battery energy storage systems in operation.

Which country has the most battery-based energy storage projects in 2022?

In 2022, the United States was the leading country for battery-based energy storage projects, with approximately eight gigawatts of installed capacity.

What are the most cost-efficient energy storage systems?

Zakeri and Syri also report that the most cost-efficient energy storage systems are pumped hydro and compressed air energy systems for bulk energy storage, and flywheels for power quality and frequency regulation applications.

Which countries need more battery storage?

Ireland and Germany’s capacities only grew by 28% from the previous year. Meanwhile, South Korea’s capacity remained the same. The International Energy Agency estimates that 1,300 GW of battery storage will be needed by 2030 to support the renewable energy capacity required to meet the 1.5°C global warming target.
