Tensor Energy and Eco Style Partner on Low-Voltage Grid Storage
The partnership targets the aggregation market for low-voltage storage, which regulatory revisions in April 2026 opened to market participation.

Tensor Energy and Eco Style have signed a business partnership to develop low-voltage grid-connected storage plants. Eco Style will handle development, construction, and O&M, while Tensor Energy acts as aggregator through its Tensor Cloud system. The companies aim to connect 1,000 units cumulatively by the end of 2027.
The agreement pairs Eco Style's solar development experience with Tensor Energy's aggregation platform. Eco Style already offers a total solution for low-voltage grid storage installable on sites as small as roughly 6 tsubo, with installation costs starting near 15 million yen.
Tensor Energy's role is to operate the assets once connected. Its Tensor Cloud system handles market bidding, charge and discharge control, and settlement for distributed storage. The companies see regulatory changes from April 2026 as the opening: low-voltage storage batteries can now enter the supply-demand adjustment market when bundled through aggregation.
The goal is a cumulative 1,000 units connected by the end of 2027, with low-voltage plants chosen for their faster grid connection timelines and suitability for idle land.
