Question

To ask the Secretary of State for Energy and Climate Change, how many wind turbines were erected in each of the last five years; and how many of those turbines have had to be repaired.

The Department does not hold information on when individual wind turbines were constructed and installed, nor on repair and maintenance of wind farm developments.

It does however hold records of wind farm developments becoming fully operational and the number of turbines associated with those developments. This information is found on the Renewable Energy Planning Database (REPD):

For reference, the following shows the number of wind turbines generating in wind farm developments that have become fully operational in the 5 years to the end of 2013:
