Solar Arrays

Lord Barker of Battle Excerpts

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.

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

This has been an interesting and worthwhile debate, although I was slightly surprised at the interesting segue into the debate taken by the hon. Member for Liverpool, Wavertree (Luciana Berger) with her little eulogy for Thomas Edison. It was enlightening, but I remind her that he also invented the electric chair. I suppose one must take the rough with the smooth.

I thank my hon. Friend the Member for Totnes (Dr Wollaston). This debate is not only important, it is extremely timely, and she has put her finger on the spot of a growing concern. I hope that this debate and the comments that I will make will nip in the bud what could be a very big problem and avert the loss of public support. I was fortunate to visit my hon. Friend’s beautiful constituency in the spring as part of a visit to Cornwall and Devon, and Transition Town Totnes is a genuinely inspiring community. What they have done and are planning to do there is a model that I hope will be rolled out in many communities across the country. Not only are they doing great things in their area, but they plan to share that with other people around the country.

I also know the hon. Lady shares my absolute conviction about the need to act against dangerous man-made climate change and about the imperative of growing the stock of renewable energy as part of our energy mix, but we have to do that in a balanced and careful way, and the two are not incompatible. Therefore, I am grateful for the opportunity to discuss what we might term the menace of inappropriate large-scale arrays, and hopefully, to allay some of the concerns that have been raised during the course of today’s debate.

As the hon. Member for Liverpool, Wavertree suggested, I am a great supporter of solar. I like to think of myself as a champion of the technology. Certainly, while I have been Minister, over the past three years, we have deployed an unprecedented level of solar; almost 2.5 GW has been deployed during that time, which is quite a record. Solar PV is a genuinely exciting technology of the future. It is flexible, intuitive, and it can be deployed in a wide range of applications and locations as part of a mixed energy economy. Whether in domestic installations, on commercial roofs, or even, on a large scale, generating for the grid, it has a strong role to play in our energy mix of the future. However, make no mistake: I am keen to see more deployment and for the UK economy to maximise the benefits that a vibrant solar PV sector will bring.

[Neil Parish]

I do not know whether the Minister will come to my point about looking again at the amount of subsidy for large-scale solar farms, so as to ensure that they are not as highly profitable and lucrative as they are at the moment.

[Gregory Barker]

I will, but I am afraid I will have to disappoint my hon. Friend.

I am on record as stating my ambition, which has also been mentioned in the debate, of seeing up to 20 GW of solar deployed in Britain, building on the terrific 2.5 GW we have deployed since the coalition came to power. Let me put that in context: if we converted only 16% of suitable commercial and industrial rooftops, or only 8% of suitable roofs on our homes, or a mix of the two, that would be sufficient to meet my big 20 GW ambition.

[Tessa Munt]

I had the pleasure of an invitation from the all-party parliamentary group for the roofing industry but a couple of days ago. I wonder whether the Minister might consider ensuring that the green deal includes all sorts of solar roof tiling, and building that in, so that every time anyone’s roof is repaired or buildings are re-roofed, they use shaped pantiles or whatever. All sorts of products are out there that can create power as well as stop the rain coming in.

--- Later in debate ---

[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.

[Sheryll Murray]

My right hon. Friend says that he will bring forward proposals in the autumn. May I reinforce to him the fact that we cannot wait until the autumn for something to be done about the planning situation? There is already a race to get a planning application in and through now. We will see our countryside destroyed unless something is done immediately.

[Gregory Barker]

I do take on board that sense of urgency. My hon. Friend will be pleased to know that the DCLG—we have been working very closely with colleagues in that Department—will bring forward, in a matter of weeks, the revised planning guidance. I believe that flexibility is already there for local authorities to exercise discretion, but we need to make that crystal clear, because as hon. Members have pointed out, there is some concern, and too often local authorities, out of fear of being challenged in the High Court, just roll over, rather than looking at the balance of community interest and visual impact, which they are quite properly able to do. We need to spell that out in a crystal-clear way that ensures that localism—local opinion—is reflected in the planning guidance.

I realise that some people treat agriculture and solar as going hand in hand with some scepticism, so I have asked my officials specifically to look into this issue directly, to look at the photographs and the materials that have been provided by my hon. Friend the Member for Totnes and not to rely on the word of developers alone. That brings me to the localism agenda.

Localism remains a fundamental keystone on which the coalition has built its policies. It runs through the coalition like the words in a stick of Blackpool rock. We remain completely committed to ensuring that the voice of local communities is strongly heard in matters that directly affect them. The deployment of renewable energy is a perfect case in point.

[Tessa Munt]

I would like to draw the Minister’s attention to a subject that he knows is one of my favourites. Many communities would feel slightly sceptical about this, particularly with regard to energy. As he knows, there is a desire on the part of communities to have power lines undergrounded through areas of particular beauty in this country. Despite the fact that 8,000 constituents of mine and other hon. Members whose constituencies neighbour mine have submitted their objections, National Grid has taken no interest whatever and there is no way to prop up that very strong community view.

[Gregory Barker]

The hon. Lady makes a very valid point. Let me reassure her: Ofgem does provide additional funding for the undergrounding of overhead cables in sensitive areas. I think that it was a great shame that the previous Conservative Government did not adopt the proposal that was lying around to underground so many pylon lines as a legacy for the millennium and instead opted to build the millennium dome. It is not that I do not like a concert—I certainly do—but I cannot help thinking that, as a gift to future generations, undergrounding the complete pylon network might have been something that we could all cheer for long after Beyoncé has departed.

[Tessa Munt]

The difficulty is that all of us here are experiencing problems in areas that are not areas of outstanding natural beauty; they are just naturally beautiful landscapes. If an area is not designated, there is no protection. Nothing is written that is strong enough to stop such ignorance of the local view.

[Gregory Barker]

I do not want to be drawn too far down that road, but there are clearly planning issues. Planning must go through due process. We are mindful of the impacts. There is a balance to be struck. Undergrounding obviously comes at a cost. In the Department, we constantly have to wrestle with the desirability of our policies versus the impact on consumer bills. When so many families are struggling with the cost of living and rising electricity and energy bills, we have been mindful of delivering cheaper bills, as well as cleaner energy and an energy infrastructure that respects our landscape.

I reiterate that I strongly believe that a local planning process, backed up by strong community engagement and robust best-practice guidance, is the most appropriate vehicle for decisions on the siting of large-scale solar PV. The national planning policy framework is clear: an application for renewable energy development should be approved only if the impact is, or can be made, acceptable. However, the framework needs to be reformed and what is and is not acceptable needs to be made far clearer. I am pleased to say that, after excellent cross-Government working, the DCLG will shortly issue new guidance setting out that the need for renewable energy does not automatically override environmental protections or the planning concerns of local communities.

My hon. Friend the Member for Totnes voiced concerns that the way the planning process treats applications could cause parts of her constituency, which are lower-grade agricultural land—pasture and land for other non-food uses—to be unduly targeted for development without considering their wider place in the local environment. That is precisely why our policies do not rely on a simple, coarse definition but require proper consideration of all the factors surrounding the siting of renewables infrastructure. The revised planning guidance for renewables, which the coalition Government will issue in the next few weeks, will state:

“The need for renewable energy does not automatically override environmental protections and the planning concerns of local communities”

and

“Care should be taken to preserve heritage assets, including the impact of planning proposals on views important to their setting”.

All the actions that I have mentioned that we are taking are important, but we accept that concerns remain and that we can do more to address concerns over the sustainability of large-scale solar arrays. I want the solar PV strategy, which we will publish in the autumn, to be informed by my solar taskforces. I also want it to be enriched by the evidence that is being provided for our forthcoming community energy strategy. I encourage all hon. Members to encourage their constituents in turn and the stakeholders to whom they are close to feed their views in to that call for evidence, to get the widest possible evidence base.

In conclusion, I am grateful to my hon. Friend the Member for Totnes for raising this timely and important issue. I reiterate that I am committed to solar PV taking its rightful place in a 21st century renewable energy mix and the UK reaping the carbon savings and economic benefits that that will bring. I remain committed to my big 20 GW vision for the UK, but not at any cost. It will come only if we continue to drive down the cost of solar towards grid parity, work with the grain of public opinion and develop solar in a way that works with local communities and does not detract unduly from our beautiful countryside.

[Sir Alan Meale (in the Chair)]

That concludes our debate today. Have a safe journey home and a good weekend.

Question put and agreed to.
