Keele University has signed a 25-year agreement with ENGIE that will see 15,000 solar panels, wind turbines and battery storage installed to support the institution's carbon neutral pledge. The renewables will collectively provide up to 50% of the campus’s electricity needs when constructed, with any excess electricity fed back into the local grid. The battery will help to provide balancing services for the local and national electricity networks, the university noted. ENGIE will fund, design, build and operate the multi-technology energy park, with the ground-mount solar panels, two wind turbines and industrial size battery housed in fields on the edge of the campus.
