§ Mr. McKelvey
asked the Secretary of State for Energy what is his latest estimate of the cost of a Severn Barrage scheme in current prices.
§ Mr. Mellor
The direct construction cost is estimated to be approximately £6,270 million at December 1981 prices. This estimate, which is subject to some uncertainty, is based on the assumptions for an inner barrage in the Severn Barrage committee's report "Tidal Power from the Severn Estuary", published as Energy Paper No. 46, revalued using the "Bulletin of Construction Indices—Civil Engineering."
