UPDATE – U.K. seeks contract manager for Severn Barrage study

The United Kingdom seeks a contract manager to oversee performance of a strategic environmental assessment of the Severn Barrage tidal power project, which could have a capacity as high as 8,640 MW. Applications are due July 2.

The U.K.’s Department for Business Enterprise and Regulatory Reform (BERR) named a consortium led by Parsons Brinckerhoff to perform the strategic environmental assessment (SEA) of the giant project, proposed for Severn Estuary between England and Wales. (HNN 5/15/08)

The SEA is to analyze how the environment around the estuary would be affected if the tidal range project proceeds. It is to consider the different technology and location options for a project and measure and assess environmental effects in areas including hydraulics and geomorphology, species and biodiversity, flood management, water quality, and compensatory habitat.

BERR seeks a professional to manage the study contract. It seeks a person with management experience on a comparable scale, preferably with coastal or marine environmental expertise and experience with SEA requirements.

An application form may be obtained from BERR’s Internet site, www.berr.gov.uk/energy/severntidalpower.

Applications are due July 2, with interviews scheduled July 15 in London. For information, contact James Marsh, (44) 20-72155029; E-mail: james.marsh@berr.gsi.gov.uk.

Tidal power proposals, assessment evidence sought

The consortium led by Parsons Brinckerhoff called for proposals through June 13 for tidal power schemes at Severn Estuary. The consortium also seeks filings by July 11 of information that that could contribute to evidence for the assessment of tidal schemes and the subsequent environmental assessment.

Other members of the consortium, which won the two-year contract in public tendering May 6, include Black &Veatch of the United States, the Environment Council, Environ, ABPmer, HR Wallingford, Hartley Anderson, and George Corderoy. BERR also named PricewaterhouseCoopers to advise on financing and ownership options for the project. (HNN 5/6/08)

Using conventional hydroelectric equipment, the proposed project would generate an estimated 17 terawatt-hours per year to supply 5 percent of the U.K.’s electricity from renewable sources. The U.K.’s Sustainable Development Commission issued a report in October 2007 that estimated the project would cost about 15 billion pounds (US$30 billion).

Project officials are to consider all tidal range technologies, utilizing the vertical distance between high tide and low tide, rather than tidal stream technology, utilizing flows. Electricity is generated by impounding water at high tide and releasing it through turbines at low tide. Tides in Severn Estuary range up to 42 feet.

The contractor consortium issued a call for evidence including two parts:
o A call for proposals by June 13 for tidal power schemes in the Severn Estuary using tidal range technology of at least 50 MW; and
o A request for any information (environmental, technical, commercial, social) by July 11 that could contribute to evidence for the assessment schemes and the subsequent environmental assessment.

The call for evidence document may be obtained from the Parsons Brinckerhoff Internet site, www.pbworld.co.uk.

Responses are to be submitted to Severn Estuary SEA Team, Parsons Brinckerhoff, Queen Victoria House, Redland Hill, Bristol BS6 6US United Kingdom; (44) 117-9339259; E-mail: severnsea@pbworld.com.
