We finance, install, and operate a battery system behind the meter at your property. You save on demand charges from day one, with no capex and no operational burden.
We assess your property
We evaluate your building's load profile, grid connection, and peak demand to size the right system.
We plan and install
Together we find the financing model that fits best: Sourceful direct, SPV, or owner-owned. We install the battery system behind the meter, sized to your load profile.
Various benefits for the property
