Severn tidal power

The Department of Energy and Climate Change published their Severn study on 18 October 2010.

It found that there was no strategic case for major public sector investment in a large-scale energy project in the Severn estuary at this time.

The Severn tidal power feasibility study showed that a tidal power scheme in the estuary could cost in excess of £30bn, making it high cost and high risk in comparison to other ways of generating electricity. The report did recommend that a Severn tidal project should not be ruled out as a longer term option if market conditions change, but noted significant uncertainty over complying with regulation and that a scheme would fundamentally change the natural environment of the estuary.
