California-based TeraWatt Technology Inc. has successfully completed the final close of its Series C funding round, bolstering its mission to expand mass production and grid-scale deployment. The latest phase of investment welcomed Japan Green Investment Corp. for Carbon Neutrality (JICN), Kyuden International Corporation, JERA Co., Inc., and ITOCHU Technology Ventures, Inc. to a roster of heavyweight backers that already includes Khosla Ventures and Temasek.
This funding round is distinguished by the entry of major strategic partners from the global energy and power sectors. TeraWatt has formalised capital and business alliances with JERA and Kyuden International, aiming to integrate its battery technology across the entire value chain. The partnership with Kyuden International focuses on exploring international battery storage opportunities, while the collaboration with JERA targets the stable supply of grid-scale cells and the commercialisation of advanced energy services.
The fresh capital is earmarked for TeraWatt’s initial mass production facility, facilitating a phased expansion of capacity. These strategic moves come at a time when energy security is becoming a paramount national concern. CEO Ken Ogata, Ph.D., emphasised that next-generation batteries are increasingly viewed as strategic assets essential for decarbonisation, infrastructure resilience, and the integration of renewable energy into the global power grid.
