Energy: Wind Generation

Volume 717: debated on Monday 8 February 2010


Asked by

To ask Her Majesty's Government what assumptions they are making about the working life of (a) land-based wind turbines, and (b) sea-level wind turbines, in their cost estimates of providing electricity from wind power. [HL1548]

The cost estimates made by the Government for onshore and offshore wind generally assume a working life of 20 years. This is used as an average figure, around which there will be a range and which itself is uncertain. Longer working lives may be achieved through a more intensive operations and maintenance programme.
