Tesla retains its first place for the second consecutive year as the leading global producer in the Battery Energy Storage System (BESS) Integrator market with a market share of 15% in 2024, according to Wood Mackenzie Energy Storage System Integrator Ranking 2025 Report.
The Chinese competitor Sungrow limits the gap, however, holds on to second place with 14% market share, which reduces Tesla’s lead in 2023 in 2023 to only one point in 2024. Colleague -Chinese manufacturer CRRC has completed the top 3 with a market share of 8%.
In particular for the North -American market, Tesla kept first place with a market share of 39%. Sungrow retained his second place, but dropped from 17% to 10% market share in 2024. Powin took third place in North America. Although he was a top 3 market player, Powin presented bankruptcy earlier this year.
The Wood Mackenzie report reveals grim regional differences in market dynamics. Chinese currant integrators saw their European market share rise by 67% on an annual basis, with four of the top 10 European players who are now headquarters in China. Conversely, the North American market share of Chinese companies fell by more than 30%, fell from 23%to 16%, mainly as a result of escalating geopolitical tensions in the US china and increased American trade protection.

“Competition between established Bess integrators remains incredibly intense,” says Kevin Shang, main research analyst, energy storage technology and supply chain for Wood Mackenzie. “Seven of the top 10 suppliers struggled last year to expand their market share and continued to be unchanged or fall.”
Seven of the worldwide Top 10 Bess integrators now have its headquarters in China, which reflects the growing influence of the country in the sector. However, intense domestic competition and oversupply have forced Chinese companies to aggressively extend to overseas markets, in particular Europe and the Middle East. Wood Mackenzie ranks sellers on the number of shipments in megawatt hours (MWH). Only shipments with income recognized in the reporting year are counted for the market share.
“The worldwide Bess -Integrator landscape is becoming increasingly complex, with regional trade policy and geopolitical tensions that reform the competitive dynamics,” said Kevin Shang, main research analyst at Wood Mackenzie. “While Tesla maintains its worldwide leadership, the rapid rise of Chinese integrators in Europe and their dominance in rising markets such as the Midden -Oosten an fundamental shift in industry. Success will increasingly depend on the ability of companies to navigate various regulatory cost.”
