Westminster Hall is an alternative Chamber for MPs to hold debates, named after the adjoining Westminster Hall.

Each debate is chaired by an MP from the Panel of Chairs, rather than the Speaker or Deputy Speaker. A Government Minister will give the final speech, and no votes may be called on the debate topic.

Diolch yn fawr iawn, Mrs Latham. It is a pleasure to serve under your chairmanship. I congratulate the hon. Member for Boston and Skegness (Matt Warman) on securing the debate. He has succeeded where I failed, but I am grateful to be able to contribute to the debate, which he led so ably.

There is no time to fall into poetic prose to describe the beauty of my constituency, but it is known as the garden of Wales—the Minister will just have to take my word for how beautiful Carmarthenshire is. I accept climate change realities, I accept the need to increase energy security, I accept the need to improve electricity distribution in our communities, especially in rural areas, and I accept the findings of the Winser report: that we are going to need a whole lot of new infrastructure to meet those challenges. I am not coming from a position of political denial.

I am facing huge upheaval in my constituency, however, because there are now four distribution and transmission routes being proposed for Carmarthenshire. In Roman times, all roads led to Rome; in west Wales, all pylons lead to Llandyfaelog, where new national grid infra- structure is being built. That is in the south of my constituency, which will be joining the new Llanelli constituency following the boundary review. That is a planning matter for Carmarthenshire County Council. All those councillors waving placards against pylon development in Carmarthenshire at the moment must use their leverage during the planning process to try and secure some of the objectives we have in mind. If they just bend the knee during the planning process, I am afraid that the backlash in the wards of Carmarthenshire will be strong. I echo the comments from the hon. Member for Boston and Skegness on the anger in our communities at the proposals.

The lines that I face are: the 132 kV Green GEN Cymru route along the Towy valley, linking an energy generation site in Powys down to southern Carmarthenshire; another Green GEN route originating in Ceredigion, going through Teifi valley and down to southern Carmarthenshire; a 132 kV National Grid Electricity Distribution proposed route along the Cothi valley; and a 400 kV National Grid route linking north and south Wales.

National Grid Electricity Distribution is the recognised distribution network operator for my part of the world. However, Green GEN Cymru is in the final stages of a licence application with Ofgem to become an independent distribution network operator. When I met the umbrella organisation for the IDNOs about a year ago and explained what Green GEN Cymru were proposing, they thought I was mad. The reality is that Ofgem are on the verge of approving an application licence for Green GEN Cymru, and there is huge concern locally about the whole process. There has been a lack of engagement by Ofgem. It is something that we are really going to have to look at. I have had no opportunity to express my concerns to Ofgem in a face-to-face meeting.

The 132 kV lines now come under Welsh Government responsibility. They used to be the responsibility of the UK Government. I had an experience with a previous line 12 years ago, which was dealt with by the UK National Infrastructure Commission. The route was undergrounded along the floor of the Towy valley following that process. I am glad that the Welsh Government are undertaking a study into new techniques, and into cable ploughing in particular.

The argument for pylons is that undergrounding is far more expensive, but the new cable ploughing technology is extremely impressive. It can be used to plough about a kilometre of line a day, and it is far cheaper than traditional undergrounding. The undergrounding analysis is based on a Parsons Brinckerhoff and Institute of Engineering and Technology report that was completed in 2012. The technology is there. I should say that the largest company in Europe happens to be based in my constituency, in Pencader.

I am asking UK Government Ministers to engage with the work of the Welsh Government and ensure that the Welsh Government have the resources to undertake that work. It could solve a lot of problems for the UK Government in the future.
