• Electrovaya says the 20-foot ElvaPulse 1500 pairs 2.88MWh of nominal energy with up to about 7MW of continuous output and can discharge its rated energy in under 30 minutes
  • UL 1973 and UL 9540 certification is targeted for Q1 2027, with initial deliveries planned for Q2 from Jamestown, New York

The fact

Electrovaya launched the ElvaPulse 1500 on 30 July, its first product in a new stationary energy-storage portfolio aimed at data centres, AI infrastructure and other critical-power applications. The 1,500-volt DC system packages up to 2.88MWh of nominal energy in a 20-foot container and is rated for approximately 7MW of continuous output. Electrovaya says it can discharge its full rated energy in under 30 minutes.

The company has started certification work under UL 1973 and UL 9540, with completion targeted for the first quarter of 2027. It is accepting production reservations and says it is in discussions with hyperscale and energy developers, but the launch announcement did not identify a customer or operating deployment. Initial deliveries are targeted for the second quarter of 2027 from Electrovaya's manufacturing facility in Jamestown, New York.

The assessment

ElvaPulse 1500 is built for short bursts of high power rather than hours of energy supply. Its 7MW rating and 2.88MWh energy capacity describe two different limits: how much power the system can deliver and how long it can keep delivering it. For data-centre operators, the product therefore has to be evaluated against a defined duty in the site's power chain, not on the MW figure alone.

How long the battery can supply power will determine where it fits in a data centre. Operators will need to match its 2.88MWh capacity to the amount of time they need it to support a load. Electrovaya has not yet demonstrated ElvaPulse in an operating data centre, and certification is still under way. For BTW readers, the first live deployment will show how customers actually use the system and whether it delivers the stated power and duration in real operating conditions.

What to watch

The first milestones are UL 1973 and UL 9540 certification, followed by Electrovaya's planned deliveries in the second quarter of 2027. After that, the focus will shift to its first named data-centre customer and live deployment. Those projects should show how the battery is used, how it connects with existing power systems and whether it delivers the performance Electrovaya has announced.
