TeraWatt Technology announced the completion of the final close of its Series C funding round, bringing in a mix of financial and strategic investors to accelerate the commercialization and deployment of its next-generation lithium-ion batteries.
The round builds on earlier participation from investors, including Khosla Ventures, Temasek, JIC Venture Growth Investments, and the Japan Bank for International Cooperation, with new backing from organizations such as Japan Green Investment Corp. for Carbon Neutrality, Kyuden International Corporation, JERA Co., Inc., and ITOCHU Technology Ventures. Several of the new investors are major players in the energy and power sectors, signaling a shift toward deeper operational collaboration beyond capital.
A central element of the funding is the formation of strategic partnerships across the battery value chain. TeraWatt has entered into capital and business alliances with Kyuden International Corporation and JERA Co., Inc. Through these partnerships, the company plans to explore global battery storage opportunities, support grid-scale deployment, and commercialize energy services. The collaboration with JERA also includes securing a stable supply of battery cells and optimizing end-to-end battery operations.
Proceeds from the Series C round will be used to expand TeraWatt’s initial mass production facility, enabling phased increases in manufacturing capacity. The company aims to pair this production scale-up with faster market deployment through its new strategic partnerships.
Founded in 2020 and headquartered in San Francisco, TeraWatt Technology Inc. focuses on developing lightweight, high-power, and safe lithium-ion batteries designed for large-scale energy applications. The company positions its technology as critical infrastructure for energy security, renewable integration, and grid resilience amid growing global demand for decarbonization.
