Partnering with UK landowners to store energy.

We’re working with landowners to identify suitable Battery Energy Storage Sites. If you have spare land, we’d like to discuss the possibility of subleasing an area on a 25-year rental agreement, which may be suitable for a BESS with a capacity of 20MW. We offer attractive annual rates of return; the process is straightforward and requires no commitment or obligation from you.
