Panasonic Commits $2 Billion to Data Center Battery Expansion, Boosts US Manufacturing
Panasonic has announced a major strategic investment of JPY 350 billion ($2 billion) to dramatically scale its battery manufacturing capacity, specifically targeting the surging power demands of AI-driven data centers. The initiative, unveiled at the company's Investors Day event in Tokyo on June 8, outlines a comprehensive roadmap to strengthen both its domestic and North American supply chains, positioning the industrial giant to capture a significant share of the rapidly growing market for energy storage in high-performance computing environments.
As part of the plan, Panasonic will introduce a dedicated production line for data center applications at its battery cell facility in Kansas, complete two additional battery module manufacturing sites in Mexico, and triple its battery cell production in Japan by fiscal year 2029. This includes repurposing the company’s vehicle line in Osaka to produce lithium-ion batteries and supercapacitors. The push reflects a broader industry shift as hyperscale data centers and AI clusters require increasingly reliable and high-voltage power backup and peak shaving capabilities.
In a presentation to investors, Panasonic outlined a suite of new products designed to meet the technical requirements of next-generation AI data centers. These include a new generation of capacitor backup units (CBUs) — high-capacity capacitors that deliver bursts of power to stabilize voltage during rapid load fluctuations — as well as battery backup units engineered for the high-voltage direct current (HVDC) architecture that data center developers are now pursuing. The company is also developing high-power lithium-ion battery cells tailored for these demanding environments.
Financially, Panasonic has set ambitious targets: tripling revenue from energy storage systems for data centers by the 2029 fiscal year, with a sales goal of nearly JPY 1 trillion ($6.25 billion). The manufacturer is aiming for a return on invested capital (ROIC) above 20% for its energy solutions business division. This investment marks a strategic pivot, following the company’s 2025 decision to exit the residential solar and energy storage market in the United States while continuing to support existing projects and warranty obligations. Panasonic remains active in the grid-scale battery energy storage system (BESS) sector, having completed a cybersecurity trial for monitoring grid-scale BESS in March 2026.
