To ask the Secretary of State for Transport what changes in unit payments for electricity have resulted from the switch by his Department to purchasing renewable energy which is exempt from the Climate Change Levy. [96488]

In response to Government targets, my Department has switched a number of its sites over to the purchase of electricity from renewable energy sources that are exempt from the Climate Change Levy. Where this has taken place, the actual average price was 4.07p/kWh, the 'standard' electricity price would have been 3.9p/kWh, so the increase due to the purchase of this renewable energy is 0.17p/kWh or 4.3 per cent.
