For electricity offtakers

Renewable electricity, day and night, without using the grid.

We build solar and battery storage next door to your site and run a private cable straight to it. You buy local power first, at a fixed price, for 10 to 15 years — with no capital cost.

The setup

Solar farm, private wire, your site.

Private wire

A direct cable runs from the solar farm to your site. Your grid connection stays in place and simply tops up the difference.

How it works

Generation next door, wired straight into your site.

Your existing grid connection stays exactly as it is. It simply tops up the shortfall when local generation and storage don't cover demand.

Because the electricity never enters the public transmission or distribution network, the network, levy and supplier charges carried by a grid kWh are largely avoided.

Battery storage

How supply is balanced.

Storage captures surplus solar during the day and discharges it after dark, extending renewable supply into the evening, reducing peak imports and improving resilience.

Who it suits

Is this a fit for your site?

  • Sites consuming more than 1 GWh a year
  • Land available near your site, or on a viable cable route
  • Extended, multi-shift or 24-hour operations
  • A need for long-term price certainty
  • ESG or Net Zero commitments to evidence

Where ground-mounted land isn't available, rooftop solar can feed your site first instead — same structure, same zero capital cost.
