The investment, which is part of a £100m initiative by Great British Energy to expand renewable power across the NHS, will be used to power Frimley Park Hospital near Camberley, Wexham Park Hospital near Slough and Heatherwood Hospital in Ascot.
James Clarke, chief strategy officer at Frimley Health, said: ‘This is fantastic news for our trust and the communities we serve. It's a big step forward in our journey towards significantly reducing carbon emissions and energy costs.'
The initiative supports the trust's commitment to cut carbon emissions by 50% over the next five years.
Over the next year, close to 4,000 solar panels will be installed across the three hospital sites, alongside energy storage systems to maximise efficiency.
Frimley Health is investing in a wide-ranging sustainability programme, aligned with the NHS's goal to reach net-zero emissions by 2040. This includes replacing approximately 9,000 light bulbs at each hospital site with energy-efficient LED alternatives.
