A total of 10.9GWh of grid-scale BESS entered commercial operations worldwide in March, up 29% year-on-year and 3% month-on-month.
That’s according to market intelligence firm Rho Motion’s Battery Energy Stationary Storage Monthly Database, and the deployments bring the overall Q1 2025 figure to 34.3GWh, a staggering 65% increase compared to Q1 2024.
The data shows that North America had its best month for deployments of grid-scale battery energy storage system (BESS) projects, deploying 742MW/2,821MWh over the month including Innergex’s 30MW/120MWh co-located BESS in Hawaii.
The four largest to become operational in the North America in March were the Anode BESS (225MW/900MWh), the Eland Solar & Storage Centre Phase 2 Hybrid (150MW/600MWh), the Antelope Valley BESS (126MW/504MWh), and Caballero Energy Storage (100MW/399MWh), all in California, US.

North America’s monthly figure was substantially higher than both January and February, when the BESS deployments were one-quarter and one-eighth of March’s figure, respectively, Rho Motion’s data shows.
Europe also had its best month of the year, seeing 706MW/1,419MWh come online. Major projects commissioned in Continental Europe that Energy-Storage.news has covered over the past month include a 53.1MWh project in Estonia and a 41MWh project in the Netherlands.

However, China continued to be, by far, the major driver of grid-scale BESS deployments globally. In March, it deployed 3,135MW/7,202MWh of grid-scale BESS, around 62% of the global total. It accounted for similar proportions in January and March.
The largest project that came online globally was there, the 500MW/1,000MWh Xinzhou Shared Energy Project in China, while a 200MW/400MWh system combining lithium-ion and sodium-ion batteries was also put into operation.
The Xinzhou Shared Energy Project was one of five projects over 500MWh that came online around the world, along with the four US ones listed earlier, plus an 880MWh project in China.
The 10.9GWh in monthly deployments brings the total cumulative installed grid-scale BESS capacity to 370.5GWh, inching up 3.2% from the previous month.
