What action does the Welsh Government intend to take to promote hydro power and geothermal power opportunities in Wales?
Wales already hosts a broad range of hydro schemes, from the major pumped‑storage stations at Dinorwig and Tanygrisiau, to many smaller community‑scale installations. In addition, smaller hydropower projects serve as great community project opportunities.
On geothermal, while it remains an emerging technology in Wales, we recognise its long-term potential—particularly for heat networks and for decarbonising hard-to-electrify sectors. We are working with partners, including the UK Government and research organisations, to better understand the resource base in Wales and to identify opportunities for pilot and demonstrator projects.
The Mining Remediation Authority assessment on disused mines has stimulated interest among local authorities and developers, encouraging them to explore projects where heat demand is located close to potential mine heat sources. The Mining Remediation Authority and the Welsh Government Energy Service continue to support projects that demonstrate strong potential.
