Floating Solar Panels

Debate between Lincoln Jopp and Miatta Fahnbulleh

Thursday 26th June 2025 Commons Chamber

[Miatta Fahnbulleh]

I recognise that point, but even with the expansion, we are still talking about only a fraction of land. Inevitably, regional and local government will make a judgment about the land that we protect. Everyone recognises that we must have prime agricultural land, because we need it, so we are making decisions, and local government will also be making decisions in that context.

[Lincoln Jopp]

I just point out to the Minister that she could save herself a vast amount of political pain, because, apart from a few swans that I saw, a couple of seagulls and one man from the Royal Society for the Protection of Birds, there ain’t many people who are going to complain about putting floating solar on raised reservoirs.

[Miatta Fahnbulleh]

I am always in the market for less pain. Let me say a little bit about some of the constraints. Eligible bids have been submitted to our contracts for difference schemes, but unfortunately none has yet been successful. That is because the cost of floating solar is about 10% to 15% higher than those of ground-mounted projects, and the reason for that is the cost of the floating structures on which the panel sits. And we hear from the sector that these can account for nearly half of the cost of the project. Moreover, floating solar requires expensive underwater cables, which costs more than land-based systems. Therefore, although we are very keen to encourage this technology and to encourage the sector to grow, there is more that needs to be done in order to make them cost effective. From a Government perspective, it is critical that every scheme and every project that we support is cost-effective, so that, in the end, taxpayers are not footing the bill for technology that is too expensive.

[Miatta Fahnbulleh]

We will always keep this area under review. We recognise the potential of the technology, and we will continue to work with industry to bring down costs. As the hon. Member says, there are reservoirs and waterways where there are potential problems, but there is also the potential for it to be painless. If we can help to unlock the technology, there will absolutely be appetite from the Government for this. We are trying to invest in research and development in this area, and we are putting in Government support and investment to unlock that.

Finally, the hon. and gallant Gentleman mentioned the solar taskforce. We are working at pace to deliver the taskforce’s recommendations. The taskforce has effectively brought together industry and Government to discuss the actions needed to scale up solar deployment, in line with our 2030 clean power mission. It has identified the need for a road map to address the specific barriers to floating solar and other innovative technologies, and a sub-group has been convened to focus on this specific topic.

[Lincoln Jopp]

I wonder whether the taskforce has engaged with the company that runs the Queen Elizabeth solar farm; it is called Bluefield—very clever name; very clever company. It wrote to the Secretary of State earlier in the year, some four months ago, but is yet to receive a reply. I would be grateful to know whether the Department is engaging with Bluefield and whether I could nudge the Secretary of State to reply to its letter?

[Miatta Fahnbulleh]

I thank the hon. and gallant Gentleman for that; his nudge has been taken, and I will pass that on to the Minister for Energy. As a Department, we are trying to engage extensively with industry on how we will take forward the complex and difficult challenges as we try to deliver our clean power mission. If companies and organisations can lend their insights and knowledge to help us develop better policy, we are always in the market for that, so I will pass on the nudge.

We are finishing the final touches to the solar road map, and it is due to be published very soon. While I will not disclose the detail of it, I assure hon. Members that the question of floating solar will be addressed within it. We recognise that floating solar is an exciting area, and we think it has huge potential for deployment in the UK. We are seeing the technology being deployed more broadly in other countries, and we want to be part of that. The hon. and gallant Gentleman has talked about the benefits for the grid, water quality, consumers of electricity and, ultimately, climate change.

There is much to like about floating solar. The challenge for us is to work with industry to ensure that we can unlock its potential. That means reducing the cost, ensuring that it is cost-effective, and ensuring that we can deploy the technology. The one commitment I will make on behalf of the Government is that we will always engage with industry as we do this work. We want the innovation, insight and experience of the brightest and the best as we try to build up our clean power sector, so we will work with industry to unlock the huge potential that we believe is there.

Question put and agreed to.
