More than 15,000 electricity generating solar panels are being installed at a new city solar farm to help power the whole of New Cross Hospital and save 1,450 tonnes of carbon a year.
The Royal Wolverhampton NHS Trust, and project partners, including Vital Energi who is delivering the project, had to overcome a number of challenges, including badgers, methane, and anti-social behaviour, to prepare the brownfield site, which is more than 40 acres - the size of 22 football pitches.
The panels, which will all be installed by October, are part of a multi-million-pound investment, provided by Salix Finance, a government-funded body, to help power the hospital for three quarters of the year – around 288 days of self-generated renewable energy.
The new solar farm will save the Trust around £15 – 20m over the next 20 years which equates to around £1m a year, money which will be put back into frontline healthcare.
Salix Finance provided the Trust with nearly £10 million in 2021 and it recently received a further £33 million to carry out green energy works as part of the Department of Business, Energy and Industrial Strategy’s Public Sector Decarbonisation Scheme (PSDS).
Rob Gray, Project Manager from the CEF, said:
“A lot of work has happened to get the site ready for the solar panels. Firstly, we had issues with the methane venting system, which is in place to release the gases from the waste material buried under the ground. Following surveys and an Environmental Agency inspection, the local authority undertook gas venting works and an additional drainage network was installed, to ensure water escaped correctly from the site to reduce standing water and flooding.
“Further to the surveys and clearing the land of trees, we also had to protect the badger setts on site by creating exclusion zones within the project for the badgers to continue to inhabit. Once the land was cleared, we installed 24-hour security.”
The solar panels will power the air source heat pumps that are being installed at the hospital by Vital Energi, along with other energy efficiency measures including steam trap replacements, pipework insulation, LED lighting, window replacements, and controls updates.
Work has also begun on the underground cabling which will connect the hospital to the solar farm.
Helen Brindle, National Account Manager at Vital Energi explained the challenges of installing the one and a half miles of private wire from the solar site across the highway, a canal bridge and a busy road junction to the hospital.
“The underground cabling has to be dug through fields and the local highway from the solar farm to the hospital,” said Helen. “This will take around four months to complete and will ensure a brand new clean, green energy source for the hospital.”
Jake Helliwell, from Salix Finance’s NHS team, added:
“Stew and the team at The Royal Wolverhampton NHS Trust are particularly determined to carry out these works to improve the energy supply of the hospital, reducing their bills in the process and freeing up resources to improve patient care. This project is particularly ambitious and time-pressured but the whole team’s energy, knowledge and passion has been invaluable in overcoming various challenges with delivery. Working with them has been an absolute pleasure.”
