To ask Her Majesty's Government what are their estimates of the costs per megawatt of (a) wind-generated electricity, and (b) nuclear-generated electricity, including construction, maintenance and grid connection costs. [HL3113]

The Government have carried out analysis on generation costs in some detail in recent years to inform policy decisions. Some of these estimates were published as part of the Energy Review (2006). Estimates made in 2007-08 suggest the following indicative levelised costs (£/MWh) associated with 1MWh of electricity generated from wind and nuclear power. These costs include construction and maintenance costs but do not include grid connection costs (which depend on location and distance from the nearest grid connection point rather than type of generation). The updating of cost assumptions for a range of generation technologies is ongoing.
