Large-scale Solar Farms

Debate between Caroline Johnson and Danny Kruger

Thursday 18th April 2024 Westminster Hall

[Dr Johnson]

I thank my hon. Friend for his contribution. I am also expecting to hear from Buckinghamshire, Wiltshire, Suffolk, Yorkshire, Redditch, the south-west and more from Lincolnshire—I do not want to miss anyone out.

The Attorney General, my right hon. and learned Friend the Member for Banbury (Victoria Prentis), and the Solicitor General, my hon. and learned Friend the Member for Witney (Robert Courts), are unable to speak today, while my hon. Friend the Member for Henley (John Howell) is unwell. Alongside Rupert Harrison, the Conservative candidate for the new Bicester and Woodstock seat, they are actively campaigning against the Botley West solar farm in Oxfordshire. If it is approved, they tell me that it will be the size of Heathrow and the largest solar plant in Europe. It will encroach across four parliamentary constituencies in Oxfordshire. A project of that scale poses a disproportionate threat to agricultural land, much of which is of best and most versatile status, and will result in the loss of swathes of open countryside. In another part of the country, my hon. Friend the Member for South Derbyshire (Mrs Wheeler) is concerned about the massive solar application on productive farmland between Rosliston and Drakelow, and the food security implications of the loss of such good farmland.

The ramifications of putting our best agricultural land out of use for 40 years could be incredibly destabilising. Arable land in the UK is declining. It is currently at 14.8 million acres, which is the lowest since world war two, with 100,000 acres being taken out of cultivation annually. Massive-scale solar plants—I call them plants specifically, because they are not really farms—withdraw hundreds of hectares of urgently needed farmland from UK food production. If such projects are allowed to go ahead, agricultural products will have to come from countries where the environmental and animal welfare standards may be less rigorous than ours, at a greater economic and—due to transportation and other things—environmental cost.

I will move on to land use strategy. Solar must take its appropriate place in the many conflicting demands on land: agriculture, housing, calls from some people for rewilding, health, and conservation. It does not trump all the others. We simply cannot have it all; we must make intelligent use of our finite resources of land and balance what some see as conflicting priorities.

Some people say that the land underneath solar panels can be grazed by livestock, but from practical experience, that is absolute nonsense. I challenge anyone to look under the ground-mounted solar panels already in place and see how often they find animals grazing there. The Government need to develop a comprehensive, carefully thought-out land strategy to ensure that our best farmland is not put at risk in this way.

[Danny Kruger (Devizes) (Con)]

I will not speak at length about the terrible development encroaching on Devizes—my hon. Friend the Member for North Wiltshire (James Gray) will speak for Wiltshire shortly—but eight of the 10 largest solar sites in England are in Wiltshire, so we have a real problem. My hon. Friend the Member for Sleaford and North Hykeham (Dr Johnson) is talking about the necessity for national planning. Does she agree that local authorities should have more power to determine a solar strategy for their area, rather than having to conform to unwieldy national rules?

[Dr Johnson]

I certainly think that local people should have more say in what happens in their area in this regard, but I am cautious about having a solar strategy for each area. In areas such as Lincolnshire with high volumes of food-producing land, it may not be appropriate to have any massive-scale solar plants.

The loss of good-quality arable land at a time of unstable world trade situations is a first-rate folly, particularly when other infinitely more sensible sites are available, such as brownfield sites, domestic roofs and commercial rooftops. This should worry everybody wherever they live, which is why it is disappointing, as my hon. Friend the Member for North East Bedfordshire (Richard Fuller) said, that the Benches are full of Conservative Members but no Liberal Democrats or Labour people with any interest in food security have turned up. Food security is important for those who live in cities, too.

Does the Minister agree that the Government urgently need to produce a joined-up land use strategy? Will he update the House on what the Government are doing to encourage the use of brownfield sites, poor-quality land, and the roofs of warehouses and industrial buildings? What discussions is he having with energy suppliers regarding the balance between standing charges and usage costs in order to incentivise the installation of solar panels on industrial units?

There is a long backlog of people waiting for grid connection. What plans does the Minister have for grid connection prioritisation for those using brownfield sites or industrial and domestic roofs? Such connections are prohibitively expensive, which is also driving the spread of massive-scale solar farms. What assessment has he made of the actual costs of the connections rather than the charged costs?

On the concept of efficiency, Hinkley Point C, which is currently under construction in Somerset, will take up 174 hectares and is expected to produce 26 TWh of electricity per year for 60 years. In comparison, Springwell Solar Farm, which is in my constituency, will be almost 25 times the size of Hinkley Point C, but will produce only 950,000 MWh of electricity per year, which is just shy of 1 TWh per year, for 40 years. That is 25 times the size for 25 times less energy, for less time.
