Tidal Power and the Severn: Can it deliver cheaper, cleaner energy?
Meeting details
The Severn Estuary Commission’s recent report claims tidal power from the Estuary could play a major role in the UK’s energy future. After an extensive study, the Commission concluded it is time to harness the "huge potential" of the Severn’s tides.
But how realistic is this ambition?
On Wednesday 7 May, the Energy Security and Net Zero Committee will hold a one-off session to examine the case for Severn tidal power. MPs will assess the feasibility, technology readiness, environmental impacts, and whether the project could help meet Net Zero targets, boost energy security, and create jobs.
The Commission has urged the Government to provide clearer policy support to attract investment and give the project regulatory certainty. However, the Government has cut funding for the Western Gateway Partnership, which had been co-ordinating early project planning. This has raised concerns among potential investors.
With technology still developing and questions over long-term viability, the Committee will also look at costs and delivery risks. Proposed projects range from a £33 billion scheme (2023 prices) producing 16,700 gigawatt hours annually, to a £7 billion option generating 2,800 gigawatt hours per year.
MPs will consider whether these could be delivered on time and on budget — and whether they would reduce energy bills enough to justify the huge investment.
The session will also explore the project’s own environmental and carbon impacts.
