Planning and Infrastructure Bill (Thirteenth sitting)

Michael Shanks Excerpts

Thursday 22nd May 2025 Public Bill Committees

[Olly Glover]

Once again, it is a pleasure to serve under your chairship, Ms Jardine.

I have moved new clause 10 and will speak to new clause 31, both tabled by the Liberal Democrats. New clause 10 would require solar panels to be provided on all new car parks and new clause 31 would create a scheme to provide financial incentives to homeowners and car park owners who install solar panels on their properties.

Clearly, the main driver of the new clauses is the climate change challenge that we face but, as I said previously in Committee, it is not just a challenge, but an opportunity: embracing more solar power generation enables us to become more self-sufficient in energy generation, and homeowners and others to reduce their energy bills. That is a good example of something that helps people, planet and economy.

New and existing car parks could provide 11.4 GW of solar capacity, which would go a long way towards reaching the Government target of 70 GW of solar by 2035. If land is already being used for a car park, why not make more use of that land and generate renewable energy? Generating energy close to where it is used means fewer energy losses, which is more efficient and makes the energy cheaper to the end user. That is an example of the sort of local electricity grids that we need to move towards in the 21st century of power generation.

Existing and new car parks, and non-domestic roofs between 50 kW and 1,000 kW, have costs comparable to solar farms, and so could be similarly economically attractive. Solar farms are predominantly rural and can require extensive planning permission and additional construction costs due to location, such as long-length cables and large transformers. Car parks also provide the opportunity to use the energy generated directly to charge electric vehicles, thereby relieving pressure on the grid and making driving electric vehicles more attractive. The Government have been clear about their aspiration for us to move to electric vehicles as standard.

In 2022, France introduced similar legislation to that which we are proposing, and it took effect in 2023. The French Government calculated that the measure will result in a capacity of between 6.75 GW and 11.25 GW. For context, Drax, the UK’s largest power station, has a capacity of between a quarter and a half of that, at just 2.6 GW. If not mandated, incentivising such schemes should be the minimum requirement. We are not using car parking space to its full potential, so I hope that the Minister will seize the opportunity to change that by supporting the new clause.

It is a pleasure to see you in the Chair, Ms Jardine. I have missed our Wednesday “Politics Scotland” soirées, so it is nice to be with you again. I will begin by speaking to new clause 10. I was going to speak to new clause 31 as well, but I do not know whether anyone intends to move it.

New clause 10, which was tabled in the name of the hon. Member for Taunton and Wellington, would require the provision of solar panels on at least 50% of the surface area of above-ground car parks. I appreciate what the hon. Gentleman is proposing, and we share his ambition. Indeed, in the “Clean Power 2030 Action Plan”, which we published just before Christmas, we outlined the pathway to achieving a clean power system. Solar photovoltaic deployment is a key component of that, and through the plan we hope to increase solar output from 18 GW to between 45 GW and 47 GW by 2030.

We were very clear in the plan that we saw solar PV as a real opportunity, but we also stated our intention to gather evidence on the potential of putting solar canopies on car parks. As the hon. Member for Didcot and Wantage pointed out, although that principle seems entirely sensible and something that I would entirely agree with, there are some details that we would want to work out on how it could be delivered and the economics of it. That is why we are consulting right now. Our call for evidence is open on the potential for mandatory installation of solar canopies on new car parks, and indeed on increasing the potential for solar on current car parks. It is important that we properly engage with industry on this question, particularly on the economics of how it could be delivered because we want to be really clear on the impact that it could have on car parks and of course on the users of car parks if costs are passed on.

I assure both hon. Members that we are in favour of the idea. Fundamentally, we want solar to be part of our pathway to clean power. If it can be deployed on the rooftops of industrial buildings, car parks, warehouses or any rooftop we can use, that clearly is the best and easiest way to do it, but we want an adequate evidence base before we do that. For that reason, we will not support the new clause, but I hope the hon. Member for Didcot and Wantage appreciates that we broadly agree with the general direction that he is proposing.
