Energy minister Greg Barker said this week project promoter Hafren Power’s plans for a Severn barrage are not detailed enough to warrant government backing.
Giving evidence to the Energy and Select Committee Barker said Hafren Power’s proposals needed more information on the cost and environmental impact.
He slammed Hafren Power’s lack information on its proposed £25bn scheme.
“This is the executive summary,” said Barker waving a thin file. “Its not exactly a warehouse.”
He said Hafren Power’s business case - which is commercially confidential - did not give any detailed information on the proposed 1,046 turbines to be used on the scheme
“We cannot take an informed view about the likely impact on the ecology nor a view of cost [without the turbine information],” Barker told the committee.
Energy experts challenged Hafren Power’s cost for the scheme particularly as it uses untested turbines last month.
A Hafren Power spokesman said he was “disappointed at the criticism of lack of detail when it has, for example, a 150 page business case from us”.
“However, we’ll keep working with the Government to supply answers and secure support to proceed.”
