Large Solar Farms

[Sir Charles Walker in the Chair]

Before the debate starts, there are quite a lot of speakers. We have had great co-operation from both Opposition Front-Bench spokespeople, who have kindly agreed not to take their allocated 10 minutes. If you are on the list to speak, I urge you, but I cannot force you, to be restrained in making interventions. We will start with a four minute time limit, but if that proves to be too long I will have to drop it.

I beg to move,

That this House has considered large solar farms.

It is a pleasure to serve under your chairmanship, Sir Charles. I thank colleagues from across the House who are attending this debate, many of whom will be highlighting issues around large solar farms in their own constituencies. I thank the Minister for attending and all those watching at home on Parliament TV.

I will briefly outline the planning process for solar farms. Solar photovoltaic panels, known as solar panels, generate electricity from the sun, and large-scale solar installations are known as solar farms. Planning is a devolved issue, but energy plants that generate more than 100 MW for offshore and 50 MW for onshore generation are treated as nationally significant infrastructure projects and a development consent order must be sought from the Secretary of State for them; solar farms that generate power below that threshold require planning permission only from the local planning authority.

The national planning policy framework provides the framework in which local planning authorities draw up local plans and determine planning applications, and encourages them to promote renewable development and identify appropriate sites for it. The goal, which is admirable, is to meet the challenges of climate change, flooding and coastal change, including our transition to a low-carbon future.

I congratulate the hon. Gentleman on securing this incredibly important debate and on his excellent speech so far. Does he agree that his assessment of the planning situation so far is the core of the issue? While we all accept that net zero is an important goal and the need for many farmers to find extra subsidies, the problem with the planning framework as it stands is that many large solar farms are being put up that generate just under the 50 MW limit, so they do not require an environmental impact assessment or the level of community input that they so deserve. Does he agree that that would be a welcome addition to the national planning policy framework that the Minister should consider?

I thank the hon. Member for her input. I agree that it is extremely important that we move on and invest in renewables, but having community input and ensuring that we choose the right sites, that people have been consulted properly and that the planning process works for everybody, is incredibly important. That is the key issue. Few people are against renewable energy, and solar farms in general are not the issue; it is very much a planning issue of getting things in the right place at the right time.

There is another point, too. Recent events in particular have shown us that we need more security, including food security, but these solar farms are often sited on grade 1 or grade 2 agricultural land, which should be used for food production. Does my hon. Friend agree that the production of energy should be as close to its consumption as possible, to minimise transmission and distribution costs? Until we have solar on every large building, there should be none in fields at all.

I thank my right hon. Friend for his comments. The threat to agricultural land is the crux of the problem, certainly in my own constituency, as I will describe a little later. With the situation in Ukraine at the moment, we have to look to our wheat supplies, and we want to source more of our food locally, because that contributes to reaching net zero, which is important too. Getting that balance right and making sure that we do not throw the baby out with bath water, so to speak, as we move forward is key. Of course, solar needs to be used in a mix with many other energy sources, so that we have a secure supply of energy, bring less of it from abroad and generate more of our own. I very much agree with my right hon. Friend.

The planning practice guidance provides more detail on renewable and low-carbon energy. It notes that

“large-scale solar farms can have a negative impact on the rural environment, particularly in undulating landscapes. However, the visual impact of a well-planned and well-screened solar farm can be properly addressed within the landscape if planned sensitively.”

That is key. The guidance also states that solar farms should be focused on

“previously developed and non-agricultural land…that it is not of high environmental value”,

as my right hon. Friend just mentioned.

The Planning Act 2008 introduced a new consent process for nationally significant infrastructure projects in order to speed up the approval process, especially for large-scale developments. A development consent order removes the need to obtain several of the consents that would have otherwise been required, including planning permission, compulsory purchase order and the like, with the idea of speeding up the process that we had before. Applications for DCOs are decided in accordance with national policy statements. In the absence of one, the Secretary of State has the power to make a decision. Although the current NPS argues for more renewable energy, it does not explicitly mention solar energy. However, a revised version is currently being considered, and an inquiry has been undertaken by the Business, Energy and Industrial Strategy Committee. The revised draft suggests guiding development away from the “best and most fertile” agricultural land and, where possible, utilising developed brownfield sites, contaminated land, industrial land or agricultural land that is preferably classification 3b, 4 or 5 rather than 1 or 2. Of course, we want to extend that to the underground cabling and access routes that will also be required with such developments. As Bassetlaw has been badly hit by flooding in the past, my constituents would add to the revised draft a requirement to make any development safe without increasing flood risks elsewhere.

I am sorry to intervene on my hon. Friend again—I know that time is pressing. None the less, he may know that the Secretary of State for Levelling Up, Housing and Communities—and more or less everything else—has made it absolutely clear that beauty should be at the heart of the planning process. Indeed, the planning process was altered by his predecessor and has been confirmed by him to do just that. No solar park of the kind my hon. Friend is describing or industrial wind turbine placed in the middle of the countryside could pass any test of beauty, except the most perverse and corrupted one.

I thank my right hon. Friend again. That is certainly an issue in our green and pleasant land. That is why I find it encouraging that there has been a move to utilising brownfield sites, not just for energy, but for housing and so on, making sure we make full use of brownfield sites before we look at our green fields and develop for the sake of developing.

Feedback from the consultants for Island Green Power claims that the soil quality is grade 3b, which would open it up to the process we have described. There are several questions about that given the high-yield crops that are grown there, including potatoes, which only grow in higher quality soils. We have already mentioned food security and energy. There is a lot of scepticism about the soil quality analysis, which is arguable, and I understand that Bassetlaw District Council is carrying out its own analysis. We need to grow more of our own food locally, not only to cut carbon emissions, but to mitigate wider problems such as the soaring price of wheat resulting from the situation in Ukraine, which is a particular concern at the moment.

I thank my constituents, including the “No Solar Desert” campaign group, who have worked hard to bring the issue to public attention and to engage thoughtfully. I had the pleasure of attending their coffee morning last week. Many are watching the debate today. It is worth emphasising some arguments made about the plans, and why local people believe the proposed site is not suitable.

The site does not meet many of Island Green Power’s selection criteria. It is not low-grade agricultural land or a brownfield site. It is near protected areas, such as the Idle Valley nature reserve. It is not flat or south-facing, and it is not near a viable grid connection, which creates another issue. Questions therefore remain about the efficiency of solar panels on this site, with some estimating it could be a low as 27%. I want to use this opportunity to throw in a reference from “Robin Hood: Prince of Thieves”—I do so regularly, as a Nottinghamshire MP:

Ynys Môn is known as energy island, as we have wind, wave, tidal, hydrogen, solar and, I hope, nuclear energy, if I have anything to do with it. My hon. Friend has spoken eloquently about the need for balance and that we are addressing efficiencies. Could he reflect on the number of jobs that solar energy creates locally?

I thank my hon. Friend for raising one of the key points. Solar is important as part of our mix, as are the other forms of energy that she mentioned. I certainly welcome the huge range of energy sources, which I know my hon. Friend campaigned hard for in Ynys Môn. The only thing that I would say to people around the country is, “Please stay away from the fusion project,” because that will happen in Bassetlaw, ideally.

The Government have made an admirable push towards renewables, but we do not want areas that would previously have been off-limits to be taken advantage of. We must cut that off at the pass. Many have also mentioned things such as greenwashing, and have rightly questioned where there is actually any local benefit to some of the schemes.

I believe that sensitive planning has an important role to play in addressing the visual impact of solar farms and, more widely, in the development of low-carbon infrastructure. It should include consideration of the character and beauty of the countryside, and whether the land is best used for solar or agricultural purposes. Thank you, Sir Charles. I look forward to hearing the contributions from colleagues in today’s debate.

Order. I call Ian Paisley—four minutes.

Thank you very much, Sir Charles. It is an honour to follow my hon. Friend from across the House, the hon. Member for Bassetlaw (Brendan Clarke-Smith), as a co-sponsor of the debate. I thank him for introducing this important subject so well. Principally, it is about large solar farms here on the British mainland, but we have similar issues challenging us in Northern Ireland. I am all for harvesting our natural resources for energy, but that policy must be consistent with others. We cannot just have carte blanche for one of them.

I will make six points, very briefly. First, solar cannot deliver power output value for land use. Secondly, large-scale solar is useless without battery energy storage plants, which can pose inherent dangers to human health and the environment. Thirdly, large-scale solar developments are a poor use of valuable agricultural land.

Fourthly, there are human rights abuses in the solar supply chain, and the UK taking economic advantage and benefit from those abuses should be called out and challenged. Fifthly, the use of coal-powered electricity in the solar panel supply chain means that we reduce our carbon footprint here at the expense of somewhere else. That is not right. Finally, there is a lack of consideration of end of life recycling of solar panels, or of those subject to being upgraded. That should also be examined.

I will focus on only three of those matters, which you will appreciate, Sir Charles. The first is the value for land use. Take, for example, Sunnica’s proposed solar development in Cambridgeshire. Sunnica claims that it will be a 500 MW solar power station, delivering 23.5 million MWh over 40 years, and it will occupy 11 sq km of valuable arable land. That is impressive. However, when you break down the facts, per year that is 588,000 MWh, which, when divided by 8,760 hours per year, is only 67.2 MW, not 500 MW. That is an important distinction because 67.2 MW is less than one seventh of the rated power of the scheme.

The Sunnica scheme is largely in my West Suffolk constituency, as well as in east Cambridgeshire; it is across the boundary. The hon. Member is quite right to draw attention to that point, but will he comment on the fact that the biggest generator of energy in the proposed scheme is a battery farm rather than a solar farm? It seems absurd that the two must be lumped together. One might almost argue that Sunnica has put a smaller solar farm on a battery project to try to build a battery farm in the middle of the Suffolk countryside.

I think that the right hon. Member has just put his finger on a very important point. That was flagged up in some of our constituencies in Northern Ireland, where it is used as cover for other applications and other things.

The Sunnica solar power station that has been applied for will take up 600 times more land to deliver the same average power as the local gas power station, so the land use is not good value for money. Those figures encapsulate just how problematic it is to expect any significant power from large solar farms.

The second issue I want to touch on briefly is that large-scale solar developments are a poor use of valuable land. In Ukraine, vast harvests of grain are gathered each year, but it is very unlikely there will be a planting season this year because of the war, and there will certainly be a very narrow harvest period at the end of this year. We get some of our grain from there; it is a bread basket for part of the world. As our country did in the last great war, we need to start setting aside vast swathes of our arable countryside and insist that we become food secure and grow our own food. I am very proud of Northern Ireland food production. With fewer than 40,000 farmers, we feed more than 10 million people in the UK. We have to multiply, develop and increase that.

It is essential that we address the key issue of allowing developers to get away with putting vast industrial plants on good, grade 1, arable land that we could grow grain on, or have cattle graze on, to develop our food security. For me, that is an essential point. The war that Russia is illegally conducting in Ukraine should be a warning signal to us all. We should get ahead of that now by ensuring we have the land planted for next year’s harvest, which is a very important point.

Finally, I want to make a point about human rights abuses. A 2021 report by the Helena Kennedy Centre for International Justice at Sheffield Hallam University, entitled “In Broad Daylight: Uyghur Forced Labour and Global Solar Supply Chains”, concluded that the solar panel industry in China has high exposure to supply chain compromise by human rights abuses—in other words, child labour and abuse of people working in those plants. We are buying plant equipment to put in this part of the UK, but allowing the abuse of people’s rights in China to do it. We should not allow China, which now dominates the world in these markets, to dominate our valuable production of—
