Commercial solar and battery storage

Solar and battery storage. Fully funded. Only if the numbers work.

We review your site, show you the numbers and, where they work, fund your battery, or solar and storage, with no capital outlay upfront. Our Energy Management System then puts your site's flexibility to work, and you receive a share of the revenue it earns.


Numbers first

Every investment decision your business makes comes down to one question: do the numbers work? Energy should be no different.

We start with your numbers, not a sales pitch. If the case isn't there, we'll tell you. And if it is, we'll fund it.


Our Energy Management System

Every site we work with gets the CSIA Energy Management System. It does two jobs.

It makes the most of your solar and battery

It forecasts your generation and demand and runs the battery to cut your costs, so you use more of your own power and buy less at peak times.

It goes beyond what a battery can do on its own

It earns from grid support services and flexibility trading. That flexibility revenue pays for our service, and you receive a share of it as a reward for making your solar and battery available. You also keep every pound of your bill savings.


What is flexibility?

Flexibility is your site's ability to take less power from the grid at the times it matters most, using your solar, your battery or both.

Since 2024, industry rules (Elexon's P415) have let a licensed trader sell that flexibility in the wholesale electricity market, with no change to your supplier. Most businesses never see that value. Our Energy Management System finds it, verifies it from your meter data and puts it to work, and you receive a share of the revenue.
