Wales Opens First Commercial Mine Water Heat Scheme in Ammanford

The Welsh Government has officially opened Wales’ first commercial mine water heat scheme in Ammanford, developed by the Mining Remediation Authority in partnership with Thermal Earth Ltd and Innovate UK.

• The scheme uses heat exchangers in mine water treatment ponds to provide low-carbon heating and hot water to an industrial unit and offices, saving an estimated 17.5 tonnes of CO₂ annually.
• The project is part of a broader initiative to explore geothermal energy potential across Britain’s coalfields, with ongoing discussions for further schemes in Wales and other UK regions.
  This project demonstrates practical, scalable mine water heat solutions contributing to Wales’ low-carbon heating transition.
