Visualized: Countries by Grid Storage Battery Capacity in 2023

The U.S. and China’s Acceleration

China has nearly half the world’s grid storage battery capacity and keeps growing at a breakneck pace. From 2022 to 2023, the country added over 19 gigawatts of storage to its grid, moving from 7.8 to 27.1 GW.

The U.S. also significantly increased its capacity in 2023, moving from 9.3 to 15.8 GW. The two largest economies account for over three-quarters of the world’s grid storage battery capacity. California’s 8.6 GW is the largest capacity of any state and more than twice that of second-place Texas.

Although Canada had only 0.4 GW of storage capacity in 2023, it quadrupled its capacity from the previous year. However, its 426% annual growth rate is still not the highest of the top 10 countries.

It was South Africa that had the largest growth rate of capacity in 2023 due to its new facility in Worcester. Its annual growth rate was 29,300%.

Not all countries in the top 10 are experiencing significant growth. Ireland and Germany’s capacities only grew by 28% from the previous year. Meanwhile, South Korea’s capacity remained the same.
