Energy BILL [ Lords ] (Fifth sitting)

Debate between Chris Heaton-Harris and Jonathan Reynolds

Tuesday 2nd February 2016 Public Bill Committees

[Chris Heaton-Harris]

There are communities out there now that are directly affected by amplitude modulation from wind turbines. I can cite Cotton farm in South Cambridgeshire. That constituency is on the border between two local authorities, both of which have passed motions in the council chamber and written to the Government asking for stronger guidance on these points.

Noise is monitored on a regular basis by a set-up in the community to scientific standards. When an onshore scheme is mooted, noise readings are taken using the same equipment, verified by a third party. Because we can predict when amplitude modulation is likely to occur—it depends on atmospheric conditions, meteorological patterns and wind speed—and can see all those factors happening in front of us, we can predict where the noise will fall. The developer can therefore be asked to shut the turbines down so that they do not cause harm, as has happened in Cotton farm a couple of times. I can absolutely see myself campaigning with other communities up and down the country to ensure that the amplitude modulation from turbines that are already up does not cause undue concern in local communities.

Initially, 10 or 15 years ago, the equipment required to set these up was very expensive. Now, it can be done for about £3,000. Most communities, and certainly a number of developers, could afford that, which would possibly take this problem away. I am trying to make the point to the hon. Member for Norwich South that there are, as my nan would say, many ways of skinning a cat.

The Government have been particularly slow to implement these provisions. I would like them to go further. I am pretty sure I could get together a decent-sized political caucus to do that. If we seriously intend to argue against part of the Bill falling under the auspices of the Salisbury doctrine, and if we are going down the line of dancing on the head of a pin over these issues, the consequences further down the line for this industry will be a lot worse than if we accepted that the Government had a clear manifesto pledge that they are effecting today.

[Jonathan Reynolds]

It is a pleasure, Mr Bailey, to be on the Committee. I had not intended to make a speech about the group of amendments but, as ever, Government Members’ contributions have led me to get to my feet. Many of their arguments have not been robust enough; many of the positions advanced have, quite frankly, been flawed and deserve further attention.

My starting point is that anyone considering the needs of our energy system right now has to admit that the most pressing priority is to ensure that our credentials for investability are maintained and strengthened. Our energy system requires billions and billions of pounds of investment, partly because so much of our generating capacity is going off line in the next few years, at the end of its natural life; partly because the capacity market has not worked as well as was hoped in incentivising new gas; partly because Hinkley C is in as much trouble as it was always going to be—we do not know whether it will ever be there when we need it—and also because we need to take coal out of the system, as a clear priority shared by all political parties. The need, therefore, to ensure that our energy structure is an attractive jurisdiction in which to invest must absolutely be maintained.

Much of the argument that has been advanced has been about the changes to onshore wind being clearly signposted in the Tory manifesto—indeed, demanded by the windy caucus, which is a wonderful new term to add to our political discourse. I do not dispute that; ideological opposition to onshore wind has been a part of the modern Conservative party for some time. I do not disagree with the legitimacy of the move any more than I disagree with the legitimacy of all the other bad things the Conservative Government are doing to the UK, but my point is that there is surely a duty on the Government to ensure that the decision is taken in such a way as not to damage the UK’s overall credentials as a jurisdiction in which to invest.

[Chris Heaton-Harris]

I do not want to be pedantic and I hope that the hon. Gentleman takes this point in the way in which it is meant. On Second Reading, we did not have Storm Henry passing through and wind was therefore producing just about 1% of our energy. At any one time, the figure flexes between 0% and, I believe, up to 18%, but it always needs gas turbines churning in the background as a back-up.

[Jonathan Reynolds]

We are straying a bit beyond the narrow remit of the Bill, but the point is an important one. On Second Reading—the hon. Gentleman and I were there—the overall figure was 5%, not 1%. It was 1% at the specific moment that the hon. Gentleman spoke—I will give him that—but in that 24-hour period it was running at about a quarter of the energy produced by our entire nuclear fleet, which is not a small contribution.

I recommend that all hon. Members take the time to go to National Grid’s control centre to see the multitude of different generating assets that can be turned on, or brought off the system, as required to keep the system in balance. That is not done as a short-term response to the current level of wind. National Grid’s weather planning system tells it exactly what it will need on certain days, and it is tremendously effective. I do not agree with the simplistic point that every megawatt of wind energy will have to have a corresponding megawatt of traditional gas generating capacity to back it up. Frankly, the people who are skilled at running our entire network do not tell me that that is the case, and I am willing to believe them given how successful they are at running the overall system.
