Strategic Expansion into Japanese Market
Energy Vault Holdings, Inc. Has completed the acquisition of an 850 MW Battery Energy Storage System (BESS) portfolio in Japan from BayWa r.e. AG, establishing a significant operational presence in the Asian market. This acquisition marks a pivotal expansion for Energy Vault into one of the most attractive energy storage markets in the world.
The acquisition includes 350 MW of advanced-stage projects expected to reach Notice to Proceed in the second half of 2027. Commercial operations are anticipated to begin in mid-2028. 500 MW of early-stage projects provide further development potential, supporting long-term growth.
By acquiring these projects, Energy Vault gains not only a premium BESS development portfolio but also an experienced local team. This team brings deep expertise in land rights, regulatory permitting, and utility interconnections, essential for scaling in Japan’s complex energy market.
Portfolio Details and Market Potential
The acquired projects are expected to have a three-hour storage duration, offering greater energy capacity per MW than typical projects in Texas. This configuration is expected to enhance long-term revenue potential and asset value in Japan’s energy market.
Energy Vault’s global owned asset base now exceeds 1.1 GW, with the Japanese projects contributing to the company’s expected annual recurring EBITDA of over $180 million. The company plans to scale its Japanese presence further by advancing these projects and exploring additional opportunities.
The strategic value of this acquisition extends beyond megawatts. It accelerates market entry and positions the company to build a long-term owned-asset platform in a market with strong demand for flexible, reliable, and dispatchable energy storage.
Energy Vault’s CEO, Robert Piconi, emphasised the significance of this acquisition, stating, “By completing this acquisition, we have secured not only a premium BESS development portfolio but also an experienced local team from one of the most respected renewable energy platforms globally in BayWa Renewables.”
Daniel Gaefke, COO of BayWa r.e., commented on the transaction’s significance for BayWa, saying, “This transaction reflects BayWa r.e.’s ability to originate, develop, and monetize premium renewable energy assets globally.”
