To ask the Secretary of State for Energy and Climate Change whether his Department has undertaken research into the cost of (a) installing and (b) maintaining (i) offshore and (ii) onshore wind turbines in relation to (A) their capacity factor and (B) the price of electricity produced in each of these ways; and if he will make a statement.

The analysis underpinning Renewable Energy Strategy, published in July 2009, used assumptions on the generating costs of different electricity generating technologies to 2020, full details of which are set out in Element (2009) and Redpoint/Trilemma (2009), which are available on the DECC website. The first table as follows summarises these generation cost assumptions with respect to wind generation in 2009, according to load factor assumptions.

In their work for the Renewable Energy Strategy (2009), Redpoint also calculated levelised costs for onshore and offshore wind for the 2009 base capital expenditure levels as follows and other assumptions in the above table. These are set out in the second table.
