Dawlish solar array at Langdon Hospital covers 60% of site power, saves NHS £185k a year

A new 1 MW ground-mounted solar array at Langdon Hospital in Dawlish was switched on in October, funded through a £3m award from a national clean energy programme run by the Department for Energy Security, Net Zero and Great British Energy. The array covers about 3.5 acres and is expected to meet 60% of the site's electrical demand, cutting the NHS trust's energy costs by roughly £185,000 per year. Battery storage is included to reduce peak demand charges and increase on-site use of the generated power. The project is part of a wider rollout by Devon Partnership NHS Trust, with six rooftop solar arrays added at other sites across Exeter, Paignton and Exmouth. The ground array uses low carbon steel construction, which the installer says cuts CO2 emissions from the mounting system by 60% compared with standard steel. For anyone tracking public sector decarbonization, this is a useful example of how grant funding and on-site generation can work together to deliver both emissions reductions and recurring operational savings.

Solid example of public sector solar. 1 MW on 3.5 acres covering 60% of a hospital site's demand, plus battery storage to cut peak charges. The £185k yearly saving is small next to NHS budgets but it's recurring, and it goes back into patient care. Low carbon steel framing is a nice extra, cuts embodied emissions without changing the panels.

Worth noting the 60% figure is electrical demand, not total energy. Hospitals have big heating and hot water loads, so the array is doing heavy lifting on the electric side. Battery storage helps with peak demand charges, but I'd be curious about how export is handled when the site isn't using the full output. Still a clean project.

The interesting part is the funding route. This came through a national clean energy programme via Great British Energy, not a trust's capital budget. That matters for other NHS sites: grants can unlock projects that would never clear internal payback hurdles. The challenge is scaling this beyond pilots. Seven sites for Devon is a start, but the NHS estate is huge.
