The installation features six 109 kWh Solis PrimePower commercial batteries, each connected to a Solis 50 kW hybrid inverter. Working in parallel, the units provide more than 600 kWh of storage capacity, allowing the hospital to make better use of its rooftop solar generation. Energy that would previously have been curtailed during the day can now be stored and used during high-demand periods or overnight, lowering electricity costs and strengthening energy resilience across the site.
Opinion: Battery storage is becoming growth infrastructure
Mark Smith, Director at ZLC Energy: "The wider renewable energy system we've delivered here will now generate between 2.5 and 3 GWh of electricity annually, enough to offset approximately 75 percent of the hospital's electricity usage, and reducing carbon emissions by approximately 600 tonnes annually."
Sandy Woodward, European General Manager at Solis: "This project represents an important milestone for Solis as our first commercial battery storage installation in the UK, at a time when demand for energy storage is growing rapidly across Europe."
Why trading is central to BESS profitability
Ben Huband, Estates Compliance & Energy Manager at The Robert Jones and Agnes Hunt Orthopaedic Hospital NHS Foundation Trust: “This project marks a significant step forward in how we manage energy across the hospital estate. By combining large-scale solar generation with battery storage, we’re able to make better use of the renewable energy being produced on site, helping reduce our reliance on grid electricity, lower costs and support our wider sustainability ambitions."
