Over the past three years, the Battery Energy Storage System (BESS) market has been the fastest-growing segment of global battery demand. These systems store electricity using batteries, helping stabilize the grid, store renewable energy, and provide backup power.

In 2024, the market grew by 52%, compared to 25% growth in the EV battery market. Among the top companies in the BESS market are technology giants such as Samsung, LG, BYD, Panasonic, and Tesla.

This graphic highlights the top 20 BESS markets by current and planned grid capacity in gigawatt hour (GWh), based on exclusive data from Rho Motion as of February 2025.

Chinese Dominance

As with the EV market, China currently dominates global BESS deployments, accounting for approximately two-thirds of installed capacity. However, other markets are expected to grow significantly in the coming years, driven by low-cost lithium-ion cells and the expansion of renewable energy capacity.

Currently, China has 215.5 GWh of installed capacity and an ambitious 505.6 GWh project pipeline. The U.S. follows with 82.1 GWh installed and 162.5 GWh planned.

Top BESS Markets	Installed 2024 (GWh)	2027P
China	215.5	721.2
USA	82.1	244.6
UK	7.5	56.3
Australia	5.6	102.9
Chile	3.8	41.0
Italy	2.2	7.9
Saudi Arabia	1.3	32.4
South Africa	1.3	9.4
Ireland	1.6	2.5
Philippines	1.0	6.1
Japan	1.0	5.0
Germany	1.0	6.2
South Korea	1.1	1.3
Israel	0.8	4.6
France	0.6	1.8
Belgium	0.7	5.3
Uzbekistan	0.6	5.9
Sweden	0.6	1.5
India	0.5	4.3
Canada	0.3	18.3

Canada is projected to be the fastest-growing market through 2027, with its cumulative capacity expected to reach 18.3 GWh—a significant increase from its current 0.3 GWh capacity.

Countries such as Australia (97.3 GWh pipeline), Saudi Arabia (31.1 GWh), and Chile (37.2 GWh) have relatively small current installations but plan substantial expansions. Within Europe, the UK leads with 7.5 GWh of installed capacity and 48.7 GWh in the pipeline, while Italy, Germany, France, and Belgium show steady but more modest growth.

Despite being technological leaders, Japan (4 GWh pipeline) and South Korea (0.3 GWh) have relatively low planned BESS expansions.

According to Rho Motion, China will remain the dominant player in 2027, but its share of the total market is expected to decline to just over 50% based on the current project pipeline.

While the BESS market is expanding, challenges remain, including grid connection bottlenecks and the development of revenue streams in emerging markets.
