Energise Barnsley

A long-term collaborative project to bring renewable energy storage solutions to capture power from solar PV installed on Barnsey Council housing stock is a shining example of how the industry can create a sustainable future.


Energise Barnsley is the UK’s largest local authority and community energy rooftop Solar PV and battery storage project. A Social Enterprise Company with key project partners, including Barnsley Council, owners of the homes where the solar PV is installed. The Council has worked hard with the Energise Barnsley team to develop protections within the solar licence and lease to give robust protection for the cash flow over the project life.


Energise Barnsley has the vision to create sustainable and cost-effective renewable solar PV and energy storage systems (ESS) within council housing stock. This vision parallels that of Immersa who were proud to be part of this ongoing project. Our consultancy experience and knowledge of the ESS market helped bring benefits to householders and contributed to valuable research.


The initial battery rollout for Energise Barnsley and Barnsley Council was the Smile B3 2.9 kW battery and M4856P expansion battery with Immersa providing delivery, installation and commissioning service. 

The initial trial has successfully concluded that batteries can be retrofitted into homes, and perform to the manufacturers stated capabilities, whilst increasing the benefit of residential solar generation and help balance the local low voltage network.

PROJECT VALUE: On-going annually £1.4m per annum.
