At the centre of the rollout is an 8.5MWp installation at Refresco's Bridgwater facility, which is expected to become the UK's largest solar PV system installed on a single continuous roof. The project will comprise more than 18,000 high-efficiency solar modules and is expected to generate approximately 7.5GWh of renewable electricity annually.

Once operational, the system is expected to supply around 17% of the site's annual electricity demand, providing a significant source of renewable power directly at the point of use and reducing reliance on grid-supplied electricity.

Refresco selected GB NRG following a competitive procurement process involving twelve leading commercial solar providers, appointing the company to develop, design, engineer and deliver the four-site programme across its UK operations.

GB NRG also took the portfolio to market on Refresco's behalf, running a competitive process that resulted in Zestec Renewable Energy being selected to fund and manage the solar infrastructure over the long term.

The projects will be delivered through Zestec’s long-term Power Purchase Agreements backed by Octopus Energy Generation managed funds.petitive procurement process involving twelve leading commercial solar providers, appointing the company to develop, design, engineer and deliver the four-site programme across its UK operations.
