Energy Provider - ESS

A long-term collaborative project to bring renewable energy to households across the UK with our energy supply partner.


Our client is the UK’s biggest green energy supplier, providing all members with 100% renewable electricity. They ensure every unit used by its members is put on the grid by a renewable source, including solar, wind and hydro. They collaborate closely with local authorities, housing associations and community energy projects to create sustainable renewable energy for homes across the UK and other parts of the world.


Our client’s vision for a green and cost-effective energy future parallels the ethos of Immersa, and we were delighted to be engaged by them to supply the battery storage solution for this project. Our initial remit was to provide 75 domestic units following our successful partnership in delivering domestic battery and installation rollout to their members as part of a trial.


To date, the project has been very successful, with 50 batteries installed in homes, with saving predicted to be an average of £460 per year. The energy supplier has reported that members have changed their behaviour, using less or cleaner energy.

PROJECT VALUE: On-going annually £1.2m to £2m.
