Renewable Energy: Cornwall

Jayne Kirkham Excerpts

Tuesday 22nd October 2024 Westminster Hall

[Valerie Vaz (in the Chair)]

I will call Jayne Kirkham to move the motion and then the Minister to respond. There will not be an opportunity for the Member in charge to wind up, as is the convention for a 30-minute debate.

[Jayne Kirkham (Truro and Falmouth) (Lab/Co-op)]

I beg to move,

That this House has considered the development of renewable energy in Cornwall.

It is a pleasure to serve under your chairship, Ms Vaz. To achieve net zero by 2030, Britain needs Cornwall. If I get anything across in the next 15 minutes, I want everyone in this room to leave with full knowledge of, and enthusiasm for, the vast and unique scale of the opportunity in Cornwall for a large-scale, thriving renewable energy sector that creates skilled jobs, brings social value to local people and generates clean energy, helping us to meet that 2030 target. It is a challenge that will require both hands to grasp, but that does not faze the people of Cornwall, who have known a rich industrial past and do not need convincing of the positives of a new industrial future.

Our riches are plentiful and unique. They are buried under our rock, under the waves that surround our 400 miles of coast, in our harsh, whistling south-westerly winds and from our come-and-go solar rays. Harnessing those riches has not always been easy, but if industrialism literally runs through the Cornish landscape, in the tin-rich veins that pass through our granite, resourcefulness runs through the blood of the Cornish. Our geography and landscape are unique and fundamental to our potential. We are surrounded on three sides by the sea, in particular the Celtic sea, which has a great water depth—Falmouth is the third deepest harbour in the world. We are sitting on globally significant mineral deposits, and our granite holds the heat of geothermal energy.

Around 37% of Cornwall’s electricity is currently generated from renewable sources, and the renewable sector already exists here: it is cutting-edge, thriving and leads the way nationally and internationally. But it is nowhere near the scale that we need to make the most of the opportunities that exist.

[Jim Shannon (Strangford) (DUP)]

I thank the hon. Lady for bringing forward this debate. As she has outlined, it is clear that we need Cornwall to achieve net zero. But it is also worth remembering that the Secretary of State said in the Chamber that this is an object for every part of the United Kingdom of Great Britain and Northern Ireland. Many other constituencies need to contribute as well. The hon. Lady puts forward Cornwall; will she also remember other parts of the United Kingdom?

[Jayne Kirkham]

The hon. Gentleman is quite correct. My point is that Cornwall has some catching up to do with other parts of the country, but I am aware that other parts of the UK are in the same situation.

The Secretaries of State for the Department for Energy Security and Net Zero and for the Department for Business and Trade visited my constituency and that of my neighbour, my hon. Friend the Member for Camborne and Redruth (Perran Moon), earlier this year, and met businesses with solutions in the marine, geo, tidal and wind spheres. The breadth of the innovation in Cornwall is huge. However, the sector needs investment along with the ambition and determination, and a long-term strategy from Government to make that vision a reality.

Under the previous Government, there was a de facto ban on onshore wind. Of planning applications for onshore wind turbines over 150 kW in Cornwall since January 2015, only one was successful in planning and has since become operational. I am very pleased that one of the first things this Government did was to end that ban on onshore wind. Community energy projects did not receive much support from the previous Government either. The rural community energy fund was only open from 2019 to 2022, and there were no new funding sources for urban community energy projects after that, except from local government.

[Andrew George (St Ives) (LD)]

I am grateful to the hon. Lady for giving way and for the case she is making today. I fully endorse everything she has said. She mentioned the previous Government’s effective ban on onshore wind: does she agree that the Conservative Government also scrapped sustainable homes regulations and other regulations, setting us back many years? We have a lot of time to make up. In Cornwall especially, there is significant enthusiasm to accelerate the pace so that we can become the green peninsula and be recognised for that throughout the UK.

[Jayne Kirkham]

I thank the hon. Member. That is true particularly around standards on homes, where our local solutions for ground source heating could have been made more of in the past and have obviously now been delayed for that reason.

The feed-in tariffs introduced by the previous Labour Government were reduced several times by the last Government and then finally ended in 2019. Despite that, the community energy sector is resilient and has continued to grow. In my constituency, Ladock won the low carbon communities challenge, and Low Carbon Ladock was given £500,000 under one of the last Governments, which it invested in solar panels on homes, biomass boilers, and ground-source and air-source heat systems. It has been able to put the profits into things for the community, such as safer school crossings, playing fields and more renewables.

The current state of play in Cornwall is that there are 104 wind turbines, 88 solar projects and two operational geothermal sites. Twenty-two projects have been granted planning permission in 2023-24 to date, including one geothermal, one onshore wind, eight battery and 12 solar photovoltaic projects. A further 22 projects have submitted planning applications in 2023-24, three of which are geothermal, four onshore wind, six battery and nine solar.

[Perran Moon (Camborne and Redruth) (Lab)]

Does my hon. Friend agree that the time to act in Cornwall is right now? We have the US State Department, which is very interested in our renewable opportunities, and representatives from France coming to Cornwall. It would be a crying shame if our Government did not use the advantages available to make Cornwall a renewable energies cluster.

--- Later in debate ---

[Jayne Kirkham]

I agree that the opportunities are vast. We have all heard incredible enthusiasm from the Secretary of State for DESNZ in particular about grasping those opportunities for Cornwall with both hands. I am pleased that that will hopefully happen.

We already know and recognise the potential for wind and solar in Cornwall. The Duchy benefits from regular south-westerly winds, which would complement those in other parts of the country. Solar has its place as well. Much of it in my constituency at present is comprised of large solar farms that cluster around the spot where the power supply is broken down into smaller distribution networks. That is only halfway down Cornwall at Indian Queens. The community benefits of those schemes are mixed, and developers have tended to focus on agricultural land that has previously been used for crops—grade 3b land, which is used for potatoes, cauliflowers and daffodils among other things.

We have geothermal solutions as well, both grid-connected with contracts for difference in place and planning permissions, such as for Geothermal Engineering Ltd, and offgrid, such as Kensa heat pumps, which I mentioned earlier. At present, there are two deep geothermal wells with the potential for three more on council farms. Geothermal is a base source producing energy day and night, and whichever way the wind blows, and the 190° water that comes out of the wells has a great scope to heat homes.

It is worth noting that there is significant Cornish capability for developing tidal streams in the UK, Europe and beyond, such as Inyanga Marine Energy Group in my constituency. There is rising demand for clean energy from critical industries such as the tech metals industry and from new communities in my constituency, such as the build of Langarth garden village.

Cornwall is blessed to have resources of tin, lithium and geothermal heat that are simply not available anywhere else. Tin is used in the manufacture of virtually every single electrical device that we use, and it is crucial to our transition to a fossil-free economy. Demand for tin over the past decade or so has driven prices even higher —so much so that is now commercially viable to reopen some of our historical mines. Investment is already coming into Cornwall, most demonstrably at South Crofty mine, where pumping out water from the flooded mine chamber is already well underway, and that of course uses an awful lot of energy.

Lithium, which is a vital component of electric vehicle batteries, is another critical mineral that we have in abundance in Cornwall. We currently import 100% of our lithium, and yet Cornwall has the largest lithium deposits in Europe. We have enough to extract 50,000 tonnes per year. Those critical minerals are currently imported from east Asia and Latin America, where they are mined in a hugely damaging way. The process in Cornwall is completely different. There is a great story to tell here: we have a way to feed the new battery factory in Somerset and to give a shot in the arm to our automotive industry without being reliant on foreign imports in a more dangerous geopolitical environment.

Floating offshore wind in the Celtic sea is the next frontier in the UK’s clean energy transition. We are positioned to unlock up to 4 GW of power by 2035, which is enough to power 4 million homes. There are huge opportunities here for Cornwall, as the Celtic sea is all around us. The ambition to put floating offshore wind in the Celtic sea, where it would complement other offshore arrays, and the opportunities that would arise from it for Cornwall to expand supply chains, the economy and the number of good, skilled jobs are vast.

However, to be brutal, ambition is so far all that it is. Test and demonstration models are planned and ready to go—smaller, non-commercial pilot projects that prove the technology works to give confidence to investors— but the most ready is stalled by too low a price from previous contracts for difference rounds, while others are stalled by planning issues.

[Noah Law (St Austell and Newquay) (Lab)]

We know the Cornish economy to be more dependent on small and medium-sized enterprises than elsewhere in the UK; the same is true of the supply chain for our great, burgeoning renewable energy industry. Does my hon. Friend agree that the organs of industrial strategy must be attuned to the need for building a supply chain based on those SMEs and the very specific needs of those growth businesses?

[Jayne Kirkham]

Absolutely—scaling up and providing the skills that are required need to be done extremely quickly. It is a race against time to remove the barriers and kick-start those projects; then, the Crown Estate, the Government and GB Energy must work together to provide a feasible timeline of contracts for difference and leasing rounds, as well as doing the groundwork by investing in the surveys and the infrastructure, such as cabling and the grid, so that investors will come on board.

Our Cornish ports and harbours, such as Falmouth, are well placed to support floating offshore wind, with well-established marine engineering solutions, servicing, assembly and maintenance. They also have a huge role to play in decarbonising shipping and defence.

This Government have already ended the de facto ban on onshore wind, and have plans for doubling onshore wind, trebling solar and quadrupling offshore wind, as well as reforming the planning system. With Cornish Lithium’s Hard Rock plant recently designated a nationally significant site of strategic infrastructure, planning could be streamlined and fast-tracked. GB Energy has been working with the Crown Estate to invest in the infrastructure that will make floating offshore wind happen and provide the certainty to draw in investment. Our new local power plan will provide £3.3 billion for grants and loans for those local energy projects—the biggest expansion in community-owned energy in history. This will enable communities to own—in the realest sense—the energy they rely on and allow local authorities, such as Cornwall, to exploit the energy sources on our doorstep, like the geothermal assets on council land that could be heating homes.

[Tom Hayes (Bournemouth East) (Lab)]

My hon. Friend is giving an excellent speech in which she is once again standing up for her communities and clean power. Does she agree that the cost of living crisis—the worst in a generation, driven by the energy shock—will cast a long shadow for as long as we remain exposed to fossil fuels, and that we must embrace British-based nuclear and Cornwall renewables? The faster we go, the more secure we become. On the point about ground source heat pumps, can she say a little about Kensa, which manufactures heat pumps in Cornwall? I was privileged to see its heat pumps last week at the Sutton Dwellings in Chelsea. They are an amazing technology.

[Jayne Kirkham]

Yes, of course. I thank my hon. Friend for drawing attention to that business, which is on the edge of my constituency. I agree that we have to embrace all sorts of energy sources—the urgency is definitely there. Kensa is one of the largest manufacturers of ground source heat pumps in Europe, but it is currently stymied by regulation and the future homes standard. Hopefully it will be able to grow in the future.

Big challenges still remain. We need to get ready for floating offshore wind in the Celtic sea; there is a risk of places such as Cornwall losing out if we are not prepared. The grid network unites renewables businesses in Cornwall because of the capacity of the distribution network, which is a key barrier and constraint to growth. There is a lack of capacity and a slow speed, and the main grid stops at Indian Queens, which is only half-way into Cornwall. We need to upgrade those transmission and distribution networks. There are significant delays to accessing grid connections for projects such as onshore charging, the energy required by the potential new Kensa factory, and tin and lithium mining.

The National Energy System Operator is newly nationalised. There will be a connections action plan to decrease the time it takes to get connected to the grid. We will need to front-load the work, do the surveys, and lay the cables to plug in all those power sources. There is currently no strategic national plan for that infrastructure.

Vital plans to lay floating offshore wind cables, and the previous Government’s miserly £160 million FLOWMIS—the floating offshore wind manufacturing investment scheme—fund for ports, were awarded with no national strategy in place. The current Government has a £1.8 billion ports fund, which is welcome. However, the French Government have just put €900 million into the port of Brest—that is the equivalent of half our entire national ports fund for the next ten years invested in just one French port. We need a coherent plan for our ports.

One of the test and demonstration models is being held up by planning, as are other projects. We need to look at planning, as well as at the huge number of skilled workers who are needed but lacking for renewables in the energy sector and to retrofit for the warm homes plan.

The Crown Estate has partnered with Falmouth marine school to pay for children aged 14 to 16 from Helston community college to receive level 2 engineering training in the sphere of offshore wind. That is a pilot; there is no ongoing funding. It is great, but it will not address the massive skills gap. We need a huge scale-up. We have great local further education providers—Truro and Penwith college and Cornwall college—but they need the ability to scale up in conjunction with the industry.

There is no national oversight of the map around the country of floating offshore wind for the future, no timescale for “test and demos”, and no pipeline of contracts with the Crown Estate to build the Celtic sea out so that the investors have certainty. We can use contractual tie-ins with the lease, and we can use procurement, but national coordinated action is needed now. We also need new domestic production targets for critical minerals.

We are ready to be the multi-renewable power production capital of the UK. It is a vision of vast scale, which is not without challenges, but it shows that Cornwall is crucial because of what we offer, rather than what we need. It is time for us to step up and become the multi-renewable power production capital of the UK.
