Infrastructure Planning (Onshore Wind and Solar Generation) Order 2025

Baroness McIntosh of Pickering Excerpts

Tuesday 6th May 2025 Grand Committee

[The Minister of State, Department for Energy Security and Net Zero (Lord Hunt of Kings Heath) (Lab)]

My Lords, this instrument, which was laid before the House on 10 March 2025, is another important step in supporting the deployment of onshore wind and solar, which are critical in achieving the Government’s clean energy superpower mission, including clean power by 2030. An effective planning system is key to unlocking the new infrastructure that our country needs to underpin our energy security and resilience. It is important that planning applications are determined through an appropriate planning route that reflects a project’s size, impact and complexity and in which potential issues are identified and mitigated as necessary.

The nationally significant infrastructure projects—NSIP—regime is governed by the Planning Act 2008, where decisions on development consent are made by the Secretary of State for the Department for Energy Security and Net Zero. The NSIP regime applies to larger projects, with a megawatt threshold determining which energy-generating projects are deemed nationally significant. The NSIP regime provides the largest, most important projects of strategic importance with a single unified approach to seeking development consent, where applications are determined by Ministers balancing local impacts against the wider national benefits. Following submission, an extensive examination period will commence whereby interested parties, including local authorities, people of office and the general public, can make written or oral representations to the examination. This ensures that the voices of communities are heard during the decision-making process.

Until recently, a de facto ban on onshore wind generation in England severely limited deployment. Changes introduced in 2015 saw stringent tests introduced into planning policy alongside the removal of onshore wind generation from the NSIP regime in 2016. These changes set an almost impossible bar to meet, resulting in the pipeline of projects sinking by more than 90%, with only 40 megawatts of onshore wind generation consented and becoming operational in the intervening period.

In July 2024, this Government disapplied those planning policy tests and committed to reintroducing onshore wind into the NSIP regime, reversing the damaging policies of the past decade and placing onshore wind on the same footing as solar, offshore wind and nuclear power stations. As such, through this instrument, onshore wind projects with a generating capacity of more than 100 megawatts in England will be consented under the NSIP regime. The 100-megawatt threshold reflects the advances in turbine technology over the past decade, with modern turbines being larger and more powerful. Reintroducing onshore wind into the NSIP regime will provide an appropriate route for nationally significant projects to seek planning consent where they are of a scale and complexity that can carefully balance local impacts against national benefits and meet the UK’s wider decarbonisation goals. This will provide greater confidence for developers and incentivise bringing forward projects.

Solar has been subject to a 50-megawatt NSIP threshold since it was originally set in the Planning Act 2008. However, much like onshore wind, solar panel technology has seen significant advances in efficiency, enabling a greater megawatt yield per site. Evidence suggests that the 50-megawatt threshold is now causing market distortion. With modern technology, mid-sized generating stations now have a generating capacity greater than 50 megawatts and therefore fall within the NSIP regime. We think this is likely to be disproportionate to their size, scale and impact, and it has resulted in a large amount of ground-mounted solar projects entering the planning system and artificially capping their capacity at just below the 50-megawatt threshold, leading to the potentially inefficient use of sites and grid connections. Therefore, this instrument raises the NSIP threshold from 50 megawatts to 100 megawatts for solar to ensure that mid-sized projects have access to a more proportionate planning route via planning authorities, which should incentivise those projects that would otherwise have capped their capacity to develop to a more optimal and efficient scale.

The Government are also mindful that mid and large-scale solar and onshore wind projects are preparing to enter the planning system and may have already invested and undertaken preparatory steps with the expectation of entering a specific regime. Changing the NSIP at short notice could result in projects entering a different regime than expected, with the potential to increase costs to developers or cause delays.

Therefore, the instrument also makes transitional provisions for onshore wind and solar projects that are already in the planning process when this order comes into force. These provisions will ensure that projects already progressing under one legislative regime will not be required to move to a different regime as a result of the order.

Through consultation, the Government sought views and supporting evidence on reintroducing onshore wind into the NSIP regime at an appropriate threshold and revising the existing threshold for solar. We received a range of responses; most respondents agreed with the proposed approach of reintroducing onshore wind into the NSIP regime, with a majority in favour of a 100-megawatt threshold. While we initially consulted on a 150-megawatt threshold for solar, based on further assessment and analysis of consultation responses, we concluded a 100-megawatt threshold would be more appropriate and better reflect modern technology.

In conclusion, we see this instrument as being another important step in delivering clean power, supporting the deployment of onshore wind and solar and establishing the UK as a clean energy superpower. It supports an effective planning system that will ensure that applications are processed efficiently through the appropriate regime and will avoid distortionary effects on deployment. These measures ultimately aim to support future energy security and resilience alongside our 2030 goals and wider decarbonisation targets. I beg to move.

[Baroness McIntosh of Pickering (Con)]

My Lords, I am grateful to the Minister for setting out the contents and the wishes of the department in this document. Personally, I am very disappointed that we are where we are. I am a veteran of pylon applications; I was fortunate enough to be elected to the Vale of York in 1997, where there was already a long line of pylons going through the heart of the Vale of York to be joined by another, even bigger, line of pylons within a matter of months of my election. We were promised that the original line of pylons would be removed because it was thought that both would not be needed and they are, of course, unsightly.

I prefer the situation we had under the outgoing Conservative Government.There was virtually a moratorium on onshore windfarms for a number of reasons. The Minister is potentially going to see a great deal of discontent from residents and communities along the route of the overhead pylons will inevitably follow, particularly onshore windfarms. To take the example of offshore windfarms, there are three stages to the application process. When there is an application for an offshore windfarm, everyone thinks, “Oh great, that won’t affect me out there at sea”. Then the second stage of the application is for a massive substation to bring the electricity on land. The third, and completely separate, stage of the application is that suddenly—hey presto—we are going to have overhead pylons to feed the electricity into the national grid. How many applications does the Minister think will fall under this new decision-making regime where onshore windfarms will be decided by the Secretary of State? How many lines of pylons does he envisage will follow on from the applications? Will his department come forward and dictate that these overhead wires should be converted to underground wires?

Alternatively, does he accept—he knows that this is a theme I have pursued quite religiously with him over the past few months—that, if an onshore wind farm is built in, say, the north of England, or in Yorkshire more specifically, the electricity generated will serve the local community? It is colder in North Yorkshire than in many parts of the rest of the country, and we have a distinct lack of electric vehicle charging points. If an onshore wind farm will be built, I see absolutely no reason why the electricity generated cannot serve the population living locally.

I regret the statutory instrument in the department’s name that the Government feel is appropriate or necessary. Solar farms of the size that the Minister is talking about—those of 100 megawatts—will take the decision out of local communities. Again, I would be interested to know how many he envisages there will be. His department, DESNZ, will not lead to many des reses. We will not have many desirable residences along the routes of these overhead pylons. In the case of the solar farms, how will the electricity generated—presumably in the gift of the Government—enter the national grid to feed into the hungry south, leaving the rest of us in heat poverty in the north?

With those few remarks, I regret that the statutory instrument was brought before us. If we learn one thing from the massive outage in Spain, Portugal and parts of France last week, it is that we are becoming completely too reliant on very unreliable sources of energy—sunshine and wind—because the sun does not always shine, and the wind does not always blow.

[Baroness Hayman (CB)]

My Lords, I declare my interest as chair of Peers for the Planet. I, too, am a veteran of this debate, but I take a different view from that of the noble Baroness, Lady McIntosh.

In 2020, I first had a Private Member’s Bill on the inequity of how planning applications for onshore wind development were treated compared with all other infrastructure. It was a simple point: the self-imposed moratorium that the previous Government had put on the development of onshore wind was done on a completely blanket basis. They took onshore wind developments out of the normal level playing field of planning applications and treated them as some sort of pariah developments that should not be used. That is completely incorrect. As part of the move towards renewables and safe, clean and cheap power, we should exploit those opportunities.

We all know that the wind does not always blow and that the sun does not always shine. After six years on this topic, I do not need to be told that any more. We all know that we have to have base capacity, that we need variety and that you cannot transition overnight, but that does not take away the argument that there was a basic inequity in how these developments were treated.

I tabled the original Bill that I mentioned. I then had another Bill the next year. We then put in amendments on a number of pieces of legislation that were going through. We even won one of them; the noble Lords, Lord Teverson and Lord Deben, and the then Opposition Front Bench supported an amendment that had remarkably similar language to this statutory instrument. We won it on the Floor of your Lordships’ House, but it was reversed in the House of Commons, so it is an enormous pleasure to welcome this SI as an example of common sense breaking out on the issue of onshore wind developmentand of the benefit and reward of not taking “no” for an answer in politics.

--- Later in debate ---

[Baroness McIntosh of Pickering (Con)]

I think I am right in saying that the seat that my noble friend represented is now represented by a different party from ours. We need the electricity in the north—I cannot speak for Suffolk—and it would be much better to keep that source of energy close to where it is produced, rather than having pylons criss-crossing and destroying the countryside.

[Lord Deben (Con)]

I am quite sure that nobody takes electricity more distantly than they need to if it is going to be used locally. In my constituency—which was indeed one of the seats lost at the last election—the issue is not a question of pylons. The issues were very different and not really to do with this at all. I come back to the point that it is not sensible constantly to refer to things that are not connected with this. I repeat that there is no connection between the outages in Portugal and Spain and the issue before us.
