Oral Answers to Questions

Debate between Lord Barker of Battle and Sarah Wollaston

Thursday 11th July 2013 Commons Chamber

[Gregory Barker]

It is fair to say that the DECC ministerial team has an unprecedented level of engagement with investors, not just from the UK but globally. Last week, I was with the Prime Minister, the Secretary of State and Masdar from the United Arab Emirates at the inauguration of the London array, the world’s largest offshore wind farm. We have proactive engagement with global investors, who all say the same thing: “We back your electricity market reforms, crack on with them, let us get deploying and get past the 13 years of under-investment that we saw under Labour.”

[Dr Sarah Wollaston (Totnes) (Con)]

15. What assessment he has made of the effect of large-scale solar arrays on rural environment and agricultural land; and if he will take steps to help communities resist inappropriate developments.

[The Minister of State, Department of Energy and Climate Change (Gregory Barker)]

Solar PV has a big, bright future in the UK, but not at any price and not in any place. Our priority continues to be to work with the industry to drive down costs, but it is also to ensure that deployment is focused on buildings and brownfield sites, not prime agricultural land or areas of outstanding natural beauty.

[Dr Wollaston]

I am delighted that the Minister shares my concern and the concern of communities in Diptford, south Devon, and other areas about the inappropriate proliferation of very large-scale solar PV on greenfield sites. Could he go further and set out the practical steps that he is taking to ensure that these developments occur in the right places?

[Gregory Barker]

My hon. Friend is absolutely right. Well-sited solar can be great and often is, but inappropriate development risks alienating public support. That is why I am pleased to say that, in the next few weeks, as a result of close work with the Department for Communities and Local Government, we will issue revised planning guidance for renewables. That will mean that renewable energy does not automatically override environmental protections and the planning concerns of local communities. It will also make it clear that care should be taken to preserve heritage assets and beautiful countryside, and include the impact of planning proposals on views and landscape when it comes to things such as solar. That is in addition to our sustainability criteria, on which we are working closely with the industry.

Solar Arrays

Debate between Lord Barker of Battle and Sarah Wollaston

Thursday 11th July 2013 Westminster Hall

[Dr Wollaston]

Yes, it is hard to believe, colleagues.

By that time, a whole generation of children will have grown up and left home in the community of Diptford, so 25 years does not sound very temporary. Furthermore, who will be responsible for decommissioning? What is to prevent these industrial wastelands from becoming tomorrow’s brownfield sites? That is another area I hope the Minister will address in summing up.

These developments have little to do with saving the planet; they are entirely about profit. The subsidies go to a tiny number of people. When I speak at public meetings, people who are in fuel poverty often ask why they are paying more to subsidise people who can afford the up-front costs of some of these developments. Indeed, these people might even have the entire cost—often including the entire planning cost—paid for them. As a result, literally nothing needs to be paid for by the person who will then have all the profit from the project.

As the Minister will know, there are many community-owned projects, and he will be aware of TRESOC—the Totnes Renewable Energy Society—in my constituency. I was proud to open its first community-owned array, which is on the roof of the local general practitioners. That is the kind of place these projects need to be. TRESOC has 502 members, who share the dividends. The point, however, is that people have to be able to afford the shares in the first place, so that automatically excludes those in fuel poverty. Will the Minister put some flesh on the bones as regards subsidies, because there are probably a lot of misunderstandings about how they operate and who benefits from them?

Will the Minister also review the system for distributing profits, so that those who suffer loss of amenity—particularly those in fuel poverty—can directly benefit from a reduction in their fuel bills? When I met AEE, it told me that Diptford residents could all benefit from the project because they could have a discount from the supplier, but only from a more expensive supplier, so it was no discount at all. That is what is fuelling a lot of the resentment about these projects.

In a recent speech, the Minister stated his ambition to have 20 GW of solar, but given the impact the 1.7 GW I mentioned will have, I hope that he will tell us, in summing up, how he will make sure that future solar, which we all feel enthusiastic about, is rolled out through community projects and brought up to scale, and that community-owned projects are supported.

Will the Minister also touch on how the national grid will cope? Another problem is that solar arrays function best at times such as this—in the middle of hot, sunny days in the middle of summer. However, peak demand will be on winter evenings, when these arrays have little, if any, input into the grid. I know they still function on cloudy days, but at times of peak demand—on dark winter evenings—they will be of no benefit at all. Another issue is that when they are functioning best—when demand is at its lowest—we also have background forms of energy generation, such as nuclear, which cannot be turned off. At the moment, our grid does not have the capacity to do that.

[The Minister of State, Department of Energy and Climate Change (Gregory Barker)]

I understand my hon. Friend’s point, and I will respond to most of her points when I sum up. However, on the issue of demand on sunny days, if she goes to any of the buildings in the centre of London on a hot day such as this, she will find a great deal of air conditioning belting out chilled air produced almost exclusively using electricity. Increasingly, office buildings, commercial buildings, public buildings and even homes need cooling on hot days such as this in the summer.

[Dr Wollaston]

I thank the Minister for his response, and I quite agree, but if we look at the statistics from National Grid, we will undoubtedly see that demand is at its lowest when solar produces its maximum output. At the moment, we do not have the capacity to store or export that energy, and nor do we have the kind of smart grid that can easily turn systems off. It would be helpful to understand a bit more about the investment that is going into the grid, so that our constituents can have the confidence that we will not be subsidising large-scale solar arrays and then turning off the electricity supply to the national grid. We want to make sure that the grid has the capacity to deal with these things.

The south-west understands that it has a responsibility to contribute to energy generation from renewables. It is encouraging that Regen SW’s figures show there has been a 50% growth in that contribution in the past year. Capacity in the south-west is now 1 GW, and 7.3% of that electricity generation comes from renewables. Devon is the major contributor, closely followed by Cornwall. Between them, Devon and Cornwall are responsible for the lion’s share of renewable energy generation in the south-west.

The real enthusiasm in the south-west, however, is for marine renewables. Those are a fabulous resource, and we have the potential to become world leaders in marine renewables. Will the Minister update us on his support for them? Other countries have taken the lead on technologies such as solar and wind, and they tend to hoover up the profits from those technologies, but Britain has the potential to be the world leader in marine renewables. I really hope, therefore, that he will be able to update us on how he plans to support marine renewables. Perhaps he could even look at a project in my constituency. Searaser was invented by Alvin Smith, and it is supported by Ecotricity. The university of Plymouth is standing ready and could carry out the tank testing of the technology, which looks very encouraging, if it had assistance to help it do so. Will the Minister look at that?

My constituents understand the need to keep the lights on, and to reduce greenhouse gas emissions and our dependence on imported fossil fuels, but they maintain that the greatest gains are in powering down and reducing energy use. We are about to spend £42 billion on High Speed 2, and I wonder what a fraction of that investment could do to transform cycling, for example, throughout the UK; to transform and electrify the entire railway system; and to invest in our vital future in marine renewables. I hope that our legacy will be in such developments. I am confident that with the Minister’s support, working closely with colleagues in the Department for Communities and Local Government, it will not be industrialisation and a wasteland across rural Britain.

[Gregory Barker]

I have thought of my hon. Friend in many ways, but I have never really thought of her as a roofer. However, I take her point: there are some interesting technologies. Building-mounted solar, and particularly, building-integrated solar—roof tiles fall under that category—is interesting. Encouragingly, the cost of the products is continuing to fall. Building-integrated solar is still relatively expensive, so it is unlikely to meet the golden rule of the green deal, but of course, green deal assessments will prompt people to consider such measures for their homes. Building regulations will also prompt developers to think about including them in homes of the future. I think there is huge potential for home-grown products, and my vision of the future is for everyone’s home to become, at least in part, a power station, and for a much more decentralised, distributed energy economy.

However, although I have big ambitions for the solar sector, let me be equally clear: deployment will not—and must not—come at any cost, nor in any place, and certainly not if it rides roughshod over the opinions of local communities. Solar has huge potential, and unlike some renewable technologies, it still enjoys huge popular support in many places. We must not allow a few badly sited or inappropriately scaled solar farms to undermine broader public support and effectively ruin it for the whole industry. I am determined to stop that happening.

Deployment of solar PV, like any other major renewable energy source, must be thoughtful, sensitive to public opinion, and mindful of the wider environmental and visual impacts. That is exactly the point that my hon. Friend the Member for South East Cornwall (Sheryll Murray)made in her excellent speech, really speaking up for the beautiful countryside in her constituency, and that point was also made by my other hon. Friends. I fully appreciate people’s worries. As my hon. Friends have described, the deployment of large-scale solar farms can have a very real, negative impact on the rural environment, particularly in very undulating landscapes. However, it is also important to say that the visual impact of a well-planned and well-screened solar farm can be properly accommodated within the landscape if done sensitively. Projects such as Powis castle and other National Trust sites are great examples of that. I was hugely impressed by the vision for a large-scale local energy park when I visited Kettering this week. It was a well-thought-out mix of onshore wind, biomass and solar, done with the consent and sympathy of the local community.

I also understand concerns about changes in land use away from agricultural use at a time when so many of us are increasingly concerned about food security and food production. We simply must not—and will not—allow prime agricultural land to be taken out of active food production. I am sensitive to people’s worries and have taken note of the specific cases highlighted by my hon. Friends the Members for Totnes and for South East Cornwall, and by my hon. Friend the Member for Tiverton and Honiton (Neil Parish). I will come back to that in greater detail, because fundamentally, I think we are on the same page.

Where are we now? What are we doing about this issue now? The fact is that my views are by no means exceptional. In fact, they are part of a broad consensus. The importance of getting the balance right and the imperative of retaining popular public support for solar is recognised by the vast majority of responsible solar companies as well. That is why the Solar Trade Association is well advanced in producing its own code of conduct for its members. I greatly welcome that initiative, which is likely to address head on the need for sensitivity to local concerns and visual amenity—so important in my hon. Friends’ constituencies; the importance of community engagement; the encouragement of dual land use; community benefits, including education and employment; and importantly, the need, at the end of its life, to return the land to its former use.

In addition, the National Solar Centre, which I was very pleased to open earlier this year, has produced detailed guidance for developers and planners, giving strict parameters to ensure that large-scale developments are sustainable. The National Solar Centre will be promoting the use of those guidelines to local planners and developers through a series of roadshows around the regions.

As welcome as those voluntary initiatives are, they are not enough. The Government have a role to play, too, so we are taking action. I have created a Government and industry taskforce to look at land use and the sustainable deployment of large-scale solar PV. The first meeting of the taskforce was just yesterday, but I have taken on board the points that my hon. Friends have made about food security, and I will ask the taskforce, which is chaired by the National Farmers Union, specifically to look into the issue and report back. The taskforce will look at how to ensure responsible and sustainable deployment and make sure that it works with communities and local planners to a localism agenda.

This complex issue requires an effective and well-considered solution. For example, we could just demand that large-scale development occur only on brownfield sites, but the simple statement “Brownfield good, greenfield bad” does not stand up to scrutiny. A brownfield site could contain a site of special scientific interest or be contained within an area of outstanding national beauty. It could be in a part of the landscape—on a hill or the side of a hill—where it can be seen for miles around. Likewise, even plots of the highest-grade agricultural land could have areas that are lower grade and could be legitimately used for solar PV deployment.

That is why—this is most important—I want to see these decisions taken locally, within the framework of sensible, robust planning guidance from the Government and strong sustainability criteria. However, as I said in a speech to the solar sector earlier this year, in general, we do have a strong preference for commercial, industrial and brownfield development. The Wheal Jane solar farm at an old tin mine in Cornwall is a very good example of where brownfield land has been used to create a solar farm.

I have set up a second taskforce, using the industry and other sectors, with the aim of maximising the quantity of solar deployed on rooftops across the country—not just for domestic households, as it will consider how to maximise deployment on industrial buildings, supermarkets, Government buildings and car parks and in other sectors. This is a huge potential resource, and we must ensure that it is exploited. As I said, just 16% of these non-domestic roofs could yield my big ambition of 20 GW.

I understand the argument, however, that some solar farms currently being deployed can scar our beautiful countryside. We need to ensure that all developers are sensitive to countryside and community. It is a fallacy to say that the deployment of ground-mounted solar PV must necessarily come with a negative visual impact, even in potentially sensitive and designated areas. The solar array at Powis castle, which I mentioned, is effectively shielded from the main visitor approach and the wider view not by industrial fencing, but by hedging. I have seen other larger arrays that sit comfortably in the landscape, and many others that do not.

We rarely hear mention of the spin-off benefits of sustainable solar PV deployment. Developers should always be encouraged to install natural visual screening such as hedges, which in themselves encourage biodiversity, by providing habitats for bird and insect life. The fallow land under solar PV panels can also encourage bird, insect and reptile life back to the fields. However, I certainly take on board my hon. Friends’ comments about the ridiculous notion that so many sites can be compatible with high-quality grazing land and the point that my hon. Friend the Member for Totnes makes about some of the pictures that are displayed in the advertising materials. That needs looking into.

I am mindful of the other side of the coin. Indeed, one responsible major PV developer, Solarcentury, has just entered into a partnership with the British Beekeepers Association to enhance the prospects for the great British bumble bee, which, I think, the hon. Member for Wells (Tessa Munt) alluded to.

[Dr Wollaston]

Does the Minister accept that spacing is also an issue? Where panels are very densely packed together, there will be very little opportunity for wildlife development. Those areas will just become wastelands and deserts.

[Gregory Barker]

Absolutely spot-on. This goes to the heart of the problem and is why we need, and will bring forward in the autumn, sustainability criteria. As my hon. Friend says, there is a very big difference between well spaced panels that are high off the ground and panels that are low to the ground and densely packed. It is almost like chalk and cheese. We must be clear what the reality on the ground is, not what it looks like in the brochure.
