Cardiff Capital Region has welcomed a report that it should be possible to harness renewable energy from the Severn Estuary.
The Western Gateway Severn Estuary Commission have published their final recommendations today. These state that not only is it possible to harness renewable energy from the one of the world’s highest tidal ranges, but that there is a clear need for collective action to take this forward. Over the last year the Commission has engaged over 500 individuals and more than 200 different organisations to understand the environmental, socio-economic, financial and engineering considerations that would need to inform such a project.
The report shows that the Estuary has strong potential to deliver sustainable energy, with the total power of its tidal range estimated to have the potential to deliver up to 7% of the UK’s total electricity despite increasing demand. In the context of national and regional net zero ambitions, and growing energy security challenges, this is an opportunity for green growth, innovation, and long-term energy resilience.
CCR’s Regional Economic & Industrial Plan recognises the need for net zero energy production facilities in the region to give greater energy security. This includes the acquisition and development of the former coal-fired power station at Aberthaw on the South Wales coast as a low carbon destination, with plans to be at the forefront of the development of tidal range turbines.

Chair of Cardiff Capital Region Councillor Mary Ann Brocklesby said:
“As a Region, we are delighted to see the report launched with a series of clear recommendations, primarily that it is feasible to harness the natural renewable energy of one of the world’s largest tidal ranges. While there is still much to be done, this is an important milestone. We look forward to working with partners across the Western Gateway, allied to Welsh & UK Governments, to drive the project forward.”
