Prevalon, the US battery storage solutions provider spun out of Mitsubishi Power Americas, intends to deploy 2.5GWh of systems using Rept Battero’s technologies this year.

The integrator entered a long-term supply deal with Chinese battery manufacturer Rept in April, for Rept’s 320Ah Wending lithium iron phosphate (LFP) cells and its modules to be used in battery energy storage system (BESS) projects.

While the scale of the deal was not publicly discussed at the time, Prevalon said last week (30 May) that it has formalised a Letter of Intent (LOI), for the deployment of 2.5GWh of systems during 2024.

The LOI marks the start of work towards a cumulative deployment target exceeding 10GWh, according to the company. It also builds upon an existing business relationship that has already seen Prevalon/Mitsubishi Power Americas use 1.5GWh of Rept batteries in US projects to date.

Prevalon was spun out of the BESS division of Mitsubishi Heavy Industries subsidiary Mitsubishi Power Americas in February, by which point it had already deployed over 3GWh of storage at 30 projects in North and South America.  

It scored its first deal post-spinout in late March with US utility Idaho Power for 82MW/328MWh of BESS equipment.

Rept cells and modules are being integrated into Prevalon’s High-Density (HD) 511 Integrated Energy Storage Platform for utility-scale applications.

HD 511 is a modular AC battery system which Prevalon claimed achieves a 360MWh per acre energy density, suitable for 2-hour to 8-hour storage applications and scalable from megawatt-hour to gigawatt-hour project sizes.

It features liquid-cooling of LFP battery modules, and provides up to 5.11MWh storage capacity in a 20-foot ISO enclosure, and runs on Prevalon’s own energy management system (EMS). The platform also includes inverters and medium-voltage (MV) transformers.

At the time of the partnership announcement two months ago, Prevalon CEO Thomas Cornell told Energy-Storage.news the Rept-manufactured cells and modules will be assembled by a third party for project delivery with input from the two partners.

Prevalon would “participate in the design part that relates to specific markets, utility requirements, grid interconnection requirements,” and then “layer its software onto that,” Cornell said.

The BESS solutions company has also been designated as service provider for Rept’s entire fleet of supplied BESS projects throughout the Americas, which Cornell said last week signified a “strategic alignment” between the pair.

Also in April, Rept signed a “renewed” supply framework agreement with US-headquartered system integrator and manufacturer Powin for 12GWh of Wending 320Ah cells, following a previous 3GWh deal. Rept also has a 10GWh supply deal in place with the BESS integration arm of gravity-based energy storage tech company Energy Vault.
