Proposed Projects
See also: Severn BarrageA list of ten proposed projects was published in July 2008. The feasibility study looked in further detail at the ten schemes and the consultation document published in January 2009 proposed that a short-list of 5 schemes should be the subject of more extensive research in phase two of the study. The 5 schemes are:
- Shoots Barrage (1.05GW scheme located downstream of the new Severn road crossing with an estimated construction cost of £3.2bn)
- Beachley Barrage (625MW scheme located further upstream of the first Severn road bridge with an estimated cost of construction of £2.3bn)
- Bridgwater Bay Lagoon (1.36GW impoundment on the English side of the Estuary with an estimated construction cost of £3.8bn)
- Fleming Lagoon (1.36GW impoundment on the Welsh bank of the Estuary with an estimated construction cost of £4.0bn)
- Cardiff-Weston (Lavernock Point to Brean Down) Barrage (8.46GW scheme, commonly known as the ‘Severn Barrage’, with an estimated cost of construction of £20.9bn).
The Government response to consultation was published in July 2009. This confirmed detailed study in phase 2 would be carried out on the 5 schemes that were recommended in the consultation document. It also announced work to bring forward 3 further schemes that are currently in the very early stages of development.
A 2009 Paper by Atkins re-evaluated the potential energy which could be generated from the various locations, and concluded that, contrary to earlier studies and computations, the maximum power potential would come from an Ilfracombe-Gower barrage, much further west than any of the schemes the Feasibility Study considered. This different conclusion was attributed to several calculation elements which were neglected in previous numerical models.

Famous quotes containing the words proposed and/or projects:
“It has been proposed that the town should adopt for its coat of arms a field verdant, with the Concord circling nine times round.”
—Henry David Thoreau (1817–1862)
“But look what we have built ... low-income projects that become worse centers of delinquency, vandalism and general social hopelessness than the slums they were supposed to replace.... Cultural centers that are unable to support a good bookstore. Civic centers that are avoided by everyone but bums.... Promenades that go from no place to nowhere and have no promenaders. Expressways that eviscerate great cities. This is not the rebuilding of cities. This is the sacking of cities.”
—Jane Jacobs (b. 1916)
