Tesla Energy held its top position in the global battery energy storage system (BESS) integrator market for the second consecutive year, capturing 15% of global market share in 2024, as per Wood Mackenzie’s latest rankings.
Tesla Energy’s lead, however, is shrinking, as Chinese competitors like Sungrow are steadily increasing their global footprint, particularly in European markets.
Tesla Energy dominates in North America, but its lead is narrowing globally
Tesla Energy retained its leadership in the North American market with a commanding 39% share in 2024. Sungrow, though still ranked second in the region, saw its share drop from 17% to 10%. Powin took third place, even if the company itself filed for bankruptcy earlier this year, as noted in a Solar Power World report.
On the global stage, Tesla Energy’s lead over Sungrow shrank from four points in 2023 to just one in 2024, indicating intensifying competition. Chinese firm CRRC came in third worldwide with an 8% share.
Wood Mackenzie ranked vendors based on MWh shipments with recognized revenue in 2024. According to analyst Kevin Shang, “Competition among established BESS integrators remains incredibly intense. Seven of the top 10 vendors last year struggled to expand their market share, remaining either unchanged or declining.”
Chinese integrators surge in Europe, falter in U.S.
China’s influence on the BESS market continues to grow, with seven of the global top 10 BESS integrators now headquartered in the country. Chinese companies saw a 67% year-over-year increase in European market share, and four of the top 10 BESS vendors in Europe are now based in China. In contrast, Chinese companies’ market share in North America dropped more than 30%, from 23% to 16% amid Tesla Energy’s momentum and the Trump administration’s policies.
Wood Mackenzie noted that success in the global BESS space will hinge on companies’ ability to adapt to divergent regulations and geopolitical headwinds. “The global BESS integrator landscape is becoming increasingly complex, with regional trade policies and geopolitical tensions reshaping competitive dynamics,” Shang noted, pointing to Tesla’s maintained lead and the rapid ascent of Chinese rivals as signs of a shifting industry balance.
“While Tesla maintains its global leadership, the rapid rise of Chinese integrators in Europe and their dominance in emerging markets like the Middle East signals a fundamental shift in the industry. Success will increasingly depend on companies’ ability to navigate diverse regulatory environments, adapt to local market requirements, and maintain competitive cost structures across multiple regions,” the analyst added.
