Solar farm powers Morriston Hospital for 50 hours without back-up from the grid in winter months

This is despite only operating during the shortest days of the year.

The £5.7m solar farm was built thanks to a loan scheme set up by the Welsh Government to decarbonise the public sector by 2030, and is repayable on an invest to save basis.

It is estimated that the hospital has already saved an estimated £120,000 in electricity bills since it was switched on in November, and is projected to save 1000 tonnes of carbon and £500,000 per year in bills when fully operational.

It has already produced 30,000 kWh surplus energy that’s been sold back to the energy grid at a profit to the hospital.

Visiting the 4MW project on Brynwhillach Farm, which is linked to Morriston by a 3km private wire, Minister for Climate Change Julie James said:

“We want our energy to come from community owned and locally run renewable energy sources in Wales.

“This will ensure our supply is resilient, reliable and reasonable for both our planet and our pockets.

“We have bold ambitions to decarbonise the public sector by 2030. Morriston Hospital- which depend not only on the powers of their staff, but also the energy hungry machines to keep their patients alive and well- have blazed the trail in their switch to renewables, which makes sense both financially and to the health of the people of Wales.

“Our addiction to fossil fuels is proving harmful, volatile and no longer viable. In Wales we will continue to accelerate our investment in renewable energy and energy efficient measures such as those adopted at Morriston hospital, and call on the UK Government to support a socially just transition to Net Zero as we respond to the climate emergency.

“The IPCC have rung the clarion call for our planet, now we must listen and respond to the science.”

Chair of Swansea University Health Board, Emma Woollett, said:

“I am delighted that the solar farm’s performance has already exceeded our initial expectations.

“The health board’s aim is to reduce its carbon footprint and maximise opportunities to use renewable energy sources.

“The solar farm will play an important part in achieving that aim, but there is also an additional benefit in terms of cost savings. It is not only lowering our electricity costs every day, but on some days covering 100% of our electricity needs.

“With the current volatile situation with energy prices, this really shows that the investment and the long-term thinking on behalf of the health board has paid off.”
