Its not going to happen any time soon. Here is the summary form the last government study. I have added a link to the whole report.
The key conclusions of the feasibility study are:
• a tidal power scheme in the Severn estuary could cost as much as £34billion, and is high cost and high risk in comparison to other ways of generating low-carbon electricity;
• a scheme is unlikely to attract the necessary private investment in current circumstances, and would require the public sector to own much of the cost and risk;
• over their 120 year lifetime, Severn tidal power schemes could in some circumstances play a cost-effective role in meeting our long term energy targets. But in most cases other renewables (e.g. wind) and nuclear power represent better value.
