Large Solar Farms

Wera Hobhouse Excerpts

Wednesday 9th March 2022 Westminster Hall

[Wera Hobhouse (Bath) (LD)]

It is important that we are aware where companies operate in this country that use absolutely unacceptable labour practices in foreign lands, so I echo what the hon. Member for Rutland and Melton (Alicia Kearns) said about the investigation into Canadian Solar, if what she says is true, but nobody in this Chamber will be surprised that I am going to make a strong case for solar.

Global gas prices are soaring to the point where many more families will struggle to heat their homes. We obviously need to wean ourselves off Russian oil and gas, but we need to wean ourselves off all oil and gas. Now is the time for a green energy revolution. Solar farms are an integral part of the UK’s bid to get to net zero and to reduce our reliance on oil and gas, yet there are many myths around solar. The first is that solar is expensive, but that is not true. Solar is the most affordable energy in history, according to the International Energy Agency, and the most affordable energy source in the UK. It is efficient and reliable.

Since 2010, the cost of solar panels has plummeted by 60%. At the same time they have become much more efficient, meaning that solar is a very effective way of reducing spending on energy costs. In 2021, solar provided almost 5% of the UK’s total electricity supply, but there is plenty of room for growth. All UK solar markets are subsidy-free. If the UK can achieve 40 GW of solar capacity by 2030, solar could meet 15% of the UK’s power needs.

Some Members today have outlined their concerns about the environment. In fact, studies indicate that solar farms can be used to boost biodiversity, improve land quality and promote the growth of pollinating species. Under the Environment Act 2021, all new developments are required to demonstrate a biodiversity net gain, and solar farms are no exception. They often go above and beyond that requirement, typically showing a biodiversity net gain of 20% to over 100%.

In terms of community support, polling shows that there is the strongest support for solar farms—over 50%—from those living closest to them, and that those living near them become more supportive over time. Once people have a solar farm in their community, they know what they get and they are supportive.

Solar projects deliver a range of benefits to their local communities, and I pay tribute to Bath and West Community Energy in my constituency, who have used their community fund to provide grants for other environmental projects in the local area. I urge the Government to review and revise Ofgem’s strategy and policy statement as a matter of urgency. The net zero target must become mandatory. It will unlock the potential investment in urgently-needed grid capacity. One of the largest constraints on solar is grid capacity. Every DNO region in the country is affected. Solar Energy UK has identified at least 45 solar projects, equating to over 40 GW of generation capacity and £1.6 billion in capital investment, that are being blocked by a lack of grid infrastructure. Many of those projects accepted offers to connect this year or next, but are now being told that they will not be able to connect until the end of this decade. That is not acceptable. The problem will get worse before it gets better.

We have the capacity to be a world leader in renewable energy, with the right political will. Now is the time for our green energy revolution. There should not be blockage but further support from the Government for the solar energy sector.

--- Later in debate ---

[Dr Alan Whitehead (Southampton, Test) (Lab)]

I will attempt to follow the hon. Member for Aberdeen South (Stephen Flynn) in being as brief as possible and finishing within five minutes, but right hon. and hon. Members will understand that we have a large number of issues to discuss.

The first thing to say is that I congratulate the hon. Member for Bassetlaw (Brendan Clarke-Smith) on securing the debate, because it gives rise to all the issues that we have to consider in the development of renewables and particularly solar. He has drawn attention to a particular scheme in his constituency, which is quite right, given his role as a constituency MP. However, I caution against expressing proper and justified concerns about the siting of particular solar farms in particular places while failing to understand just how much we need renewables, especially of the solar variety, over the next period.

I have just come from the statement in the main Chamber, and all sides agreed that our way out of the oil and gas problem, which has been driven by the situation in Ukraine and Russia, is to go very fast on renewables. The point is that if we go fast on renewables, the renewables have to be somewhere, and it is really not sufficient for people to say, “Yes, I’m very much in favour of renewables, but I’m not in favour of them being in any particular place.” I am not saying that that is what right hon. and hon. Members have said this afternoon, and a number of Members were very thoughtful and clear about the circumstances under which solar should be developed. I think that should perhaps be the watchword, and I agree with a number of Members that we need a much more strategic and planned approach to the arrangements. We need to understand what renewables we need, but also where we need them. However, it is not an option to have them nowhere at all.

In that context, we know that solar has already been a considerable success in the UK. It is being developed at the moment on no subsidies. We have 14 GW installed across the country, and 65% of that is ground-mounted solar. Frankly, it is a fantasy to believe that we can get to the sorts of targets we now need on solar—perhaps 40 GW by 2030, which is what the Climate Change Committee says—by simply installing them in small numbers on roofs in cities and towns. Of course we should go with that, and we ought to have a lot more imagination about how we put solar in towns and cities or alongside motorways and various things such as that.

[Wera Hobhouse]

I agree with everybody that not engaging with communities is simply not on, and it is important that those who want to install renewable energy installations and solar farms need to engage with their communities. What does the hon. Gentleman think should be done to improve community engagement?

[Dr Whitehead]

The hon. Member is quite right. Any form of renewable power—indeed, any form of power—ought to be based on extensive community consultation and the community being on board with the idea of that particular power source coming to their area. Hon. Members have raised a number of issues about agricultural land and its quality, the visual aspects of particular solar farms, and various other things, which need to be discussed in great detail at the local level by communities faced with these proposals.

Solar farms, and particularly the West Burton solar farm, which was the subject of the concerns raised by the hon. Member for Bassetlaw, actually have quite a good grid connection. That solar farm would potentially be based around the West Burton A power station, which as I am sure the hon. Member will be aware is going offline in 2022, as is the Cottam power station just down the road. However, if we had had a discussion when someone decided to build the West Burton A power station and the Cottam power station in the middle of the countryside—which is where they are—a number of years ago, we probably would have had exactly this sort of debate in the Chamber.

That underlines the fact that, although we are transferring what we do as far as power stations and power are concerned, the issue remains just the same: where we put those power stations and renewables into operation, not whether we put them into operation. It is imperative that we have this amount of renewable energy across our country for the future. Be it offshore wind or onshore wind, city-based solar or field-based solar—all of those have to be considered as imperative for delivering our renewable power supplies. Solar happens to be the cheapest power available, and it is one of the quickest to introduce if we are thinking about a dash for renewables in the future.
