Battery systems that store energy for the grid.

We install lithium-ion batteries from all the major manufacturers — Tesla, Fluence, Wartsila, BYD, CATL, Powin, and others. Our crews train on multiple platforms, so we can work with whichever supplier the project chooses, and we coordinate closely with their commissioning team.

Standalone batteries connect directly to the grid through their own inverter. Paired systems share inverters with a solar farm or wind project — more efficient but more complex. We build both. For new projects, standalone is more common; paired systems are popular when developers want to maximize tax credits.

Yes — and bundling both saves time. The same crews and engineers handle the battery pad and the substation, working in parallel. A typical 9–14 month substation build can land in 7–10 months when both are under one contract.

Augmentation is replacing battery cells or racks mid-life to restore the system to its original rated capacity. Lithium-ion batteries lose about 2% capacity per year, so most projects schedule augmentation every 5 to 10 years. Yes, we handle this work — and we sequence it around the developer’s outage windows, not the manufacturer’s.

From 10 megawatts (single-site community projects) up to 400 megawatts (large utility-scale systems). Storage duration typically runs 2 to 8 hours, depending on what the project is meant to do.
