Onshore Wind Turbines

Debate between Hugh Bayley and Chris Heaton-Harris

Wednesday 13th October 2010 Westminster Hall

[Chris Heaton-Harris (Daventry) (Con)]

I hope that there will be a number of interventions from colleagues, so I do not intend to fill my 15 minutes; other hon. Members might want to speak. I believe that the Government urgently need to reassess their views about the production of onshore wind power.

[Hugh Bayley (in the Chair)]

Order. Before the hon. Gentleman gets into his stride, I should say that the rules governing 30-minute debates allow for interventions on the hon. Gentleman, or the Minister when he replies, but I have not been notified of an agreement between the hon. Gentleman and the Minister for others to speak. Therefore, if colleagues plan to open their mouths during this debate, it will have to be in the form of an intervention. I hope that that is helpful, and I apologise to the hon. Gentleman for interrupting his speech.

[Chris Heaton-Harris]

Thank you for clarifying that for me, Mr Bayley. This is my first Adjournment debate and I had no idea what the rules were. Over the next few minutes I will try to explain why I think that the Government need to change their position on onshore wind—I will obviously speak for slightly longer than the eight or nine minutes on which I was planning, but perhaps Members who would like to intervene can help out.

I have a number of questions about that area of policy. The current official Government figure for carbon displacement by wind power assumes that wind power can replace conventional generation at 100% efficiency. That is clearly unrealistic in view of the technical challenges of incorporating an intermittent and highly variable power source into a strictly managed supply system. Reports from Denmark and Germany suggest that the carbon costs of absorbing wind power into the grid are substantial. I assume that that is also true for the UK.

A substantial proportion of electrical power demand is continuous—the base load. The balance is required to respond to demand that fluctuates in many ways, including seasonally, instantaneously, or even at the end of an England game—or, if it was last night’s game, not at all. There is no effective or economic way of storing energy on a large scale. Therefore, we have a number of conundrums. The key responsibility of the grid is to ensure that the demand for power is met at all times. That is achieved by ensuring the availability of capacity when needed, and avoiding the generation of unusable power.

I would like the Minister to have time to reply.

There are particular issues with the science behind noise and how DECC handles its contracts and contractors.

[Hugh Bayley (in the Chair)]

Order. The comment about the Minister needing time to reply is an extremely good one.

[Chris Heaton-Harris]

Thank you very much, Mr Bayley; I was about to sit down.
