Rhondda Cynon Taf (RCT) Council in Wales has submitted planning applications for two hydroelectric schemes in Treforest and Aberdare. The projects aim to support the Council’s carbon reduction goals and increase its renewable energy output, as outlined in the Corporate Plan (2024-2030).
The proposals include a low-head hydroelectric system at Treforest Weir and a micro-generation scheme at Dare Valley Country Park. Both projects are designed to harness the flow of natural water to generate electricity for Council assets, with any surplus energy exported to the grid.
Details of the plans have been added to the RCT Planning Portal, where residents can review and comment on the proposals. Public feedback will be considered by the Planning and Development Committee during the determination process.
Treforest Weir hydroelectric scheme
The proposed scheme at Treforest Weir, a Grade II-listed structure on the River Taff, involves replacing the existing fish pass with hydropower infrastructure. A modern fish pass with equal or improved performance would also be installed.
The system is expected to generate over 1110MWh of electricity annually, enough to power multiple Council facilities. Preliminary designs and site surveys have been completed, and the project requires additional permissions from Natural Resources Wales (NRW).
Dare Valley Country Park Scheme
At Dare Valley Country Park, the proposal involves a 50kW micro-hydro system on the Dare River. The project would generate about 193MWh of electricity per year, with 80% powering the park’s hotel and visitor center. The remaining 20% would be exported to the grid.
The scheme involves installing an intake at an upper pond, pipework and cabling between locations, and a powerhouse near the lower pond. A full ecological assessment has been completed, with measures planned to protect local biodiversity.
Councillor Christina Leyshon, Cabinet Member for Climate Change, highlighted the projects’ significance in advancing the Council’s climate objectives. “These proposals for the Treforest Weir and Dare Valley Country Park demonstrate the Council’s innovative approach to carbon reduction and producing cleaner energy,” she said.
“The Council is very committed to its climate change goals and responsibilities. To achieve our ambitious targets, we must invest in clean energy generation, which is why the Treforest and Aberdare projects have been in development.”
