Electrovaya launches high-power ElvaPulse 1500 BESS for data centers, signs commercial deal with Amazon

Canadian lithium-ion battery developer Electrovaya has entered the data center energy storage market with the launch of a new stationary battery energy storage system (BESS) designed specifically for mission-critical facilities. The move comes as data center operators increasingly seek high-power, space-efficient energy storage solutions to support AI-driven computing loads and grid resilience requirements.

The newly unveiled ElvaPulse 1500 is housed in a 20-foot modular container and delivers up to 2.88MWh of energy capacity with approximately 7MW of continuous power. The system is built around Electrovaya's proprietary ceramic separator technology, the same platform that underpins its Infinity Battery line. According to the company, the unit's power-to-energy ratio enables full discharge in just 30 minutes, significantly shorter than the industry-standard 2-to-4 hour discharge window. Electrovaya says this makes the system one of the highest power-dense offerings on the market, better suited to supporting mission-critical operations where rapid, reliable power delivery is essential.

"Data centers and other mission-critical facilities are pushing the energy storage industry toward higher and higher power delivery, and ElvaPulse 1500 was purpose-built to meet that need," said Raj DasGupta, CEO of Electrovaya. "With up to 7MW of continuous power from a single 20-foot container, ElvaPulse 1500 offers the highest power density available in a stationary lithium-ion platform today, while bringing the proven safety and longevity of our Infinity Battery Technology to these demanding applications."

The company said it is in active discussions with hyperscale and energy developers regarding ElvaPulse deployments and is currently accepting production reservations. Deliveries from its Jamestown, New York, manufacturing facility are expected to begin in 2027.

In a related development, Electrovaya announced last month a commercial agreement with Amazon designed to support the continued deployment of its battery technology, as well as foster greater collaboration on robotics and energy storage applications. As part of the agreement, Amazon will receive warrants to purchase up to 13,880,345 common shares of Electrovaya, which become fully vested upon Amazon achieving cumulative future purchases of $280 million.

"Electrovaya's Infinity Battery Technology has demonstrated real performance in demanding material handling environments, and this agreement with Amazon reflects our confidence in the opportunity ahead. We look forward to building on that foundation in other industrial applications where safety and longevity are critical," said DasGupta.

Electrovaya, headquartered in Toronto, Canada, is a lithium-ion battery developer focused on industrial, robotics, defense, and energy storage applications. The company's Infinity battery energy storage systems are modular, delivered within a 20-foot container, and explicitly target grid, industrial, and data center support applications. In April, the firm was selected to participate in a US Department of Energy (DOE) funded project to test the feasibility of integrating BESS within a data center environment.

The launch underscores a broader industry trend: as AI workloads drive unprecedented power density demands, data center operators are moving beyond traditional backup power approaches to adopt advanced energy storage systems that can deliver high power in compact footprints. Electrovaya's entry into this segment reflects the growing convergence of energy storage technology and data center infrastructure, with implications for both operational resilience and grid stability.
