Renewable Energy: Cornwall

Tuesday 22nd October 2024 Westminster Hall

11:00

[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.

[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.

[The Parliamentary Under-Secretary of State for Energy Security and Net Zero (Kerry McCarthy)]

It is always a pleasure to see you in the Chair, Ms Vaz. I thank my hon. Friend the Member for Truro and Falmouth (Jayne Kirkham) for securing this debate and the other Members for their contributions. It is good to see a clean sweep of new MPs in Cornwall, although my hon. Friend the Member for St Ives (Andrew George) is a familiar face from days gone by. The passion of hon. Members for the region shines through, and all six MPs are brilliant advocates for Cornwall’s sheer potential.

I want to note the recent letter from the four Labour MPs in Cornwall to the Minister for Industry, the hon. Member for Croydon West (Sarah Jones), concerning the need for investment in the county. As the hon. Member for Truro and Falmouth mentioned, the Minister for Industry and the Secretary of State for Business and Trade have visited the region recently. I know that both are aware of the county’s incredible potential for economic and industrial growth. I understand that the four MPs will be meeting my colleague, the Minister for Industry, very soon to discuss the issues raised in the letter.

My hon. Friend the Member for Truro and Falmouth will be aware that one of the Prime Minister’s five missions for national renewal is making Britain a clean energy superpower, including delivering clean power by 2030 and accelerating to net zero. As has been mentioned, we have wasted no time in getting started. Within our first 100 days in government, we lifted the onshore wind ban in England, consented to more nationally significant solar projects than had been consented to in the past 14 years, and delivered the most successful renewables auction in British history. Now we are busy setting up Great British Energy, which will drive clean energy deployment, creating jobs, boosting energy independence and ensuring that UK taxpayers, bill payers and communities reap the benefits of clean, secure, home-grown energy. As we heard, Cornwall has a vital role to play in that clean energy mission, and indeed our mission to secure economic growth.

Cornwall may be primarily known as a tourist destination these days, but it has a proud industrial past. It was once known as the mining capital of the world, with tin mining and clay, and was where Richard Trevithick invented the high-pressured steam engine. As much as tourism is welcomed in Cornwall, we know that it puts pressure on the local infrastructure and economy, particularly the housing supply, which then has a knock-on effect on public services in the area.

From meeting local businesses in Cornwall when I went down with the now Chief Secretary to the Treasury last year, I know that there is excitement about the opportunities offered by Cornwall’s huge industrial potential from wind, geothermal, lithium and more. Great work is already being done through the continuing development of a local area energy plan in Cornwall and Isles of Scilly, and the Government are doing what they can to support the region too. Last September, three geothermal projects, all located in Cornwall, were successful in our contracts for difference auction for the first time, with contracts totalling 12 MW of generation. As part of my visit to Cornwall last year, I also went to see some of the exciting work that the Eden Project is doing on geothermal.

Critical minerals have been mentioned as an important area for future industrial development. Cornwall has some of the largest critical mineral deposits, with research showing that the county alone could meet more than half the UK’s 2030 demand for lithium, which is an essential part of the electric vehicle battery supply chain. As we transition to a renewables-based economy, the demand for critical minerals will only grow, and I note the concerns that have been raised about current sourcing and the need to diversify supply. Indeed, Cornwall is home to at least three of the 18 critical minerals, and I hope that local MPs, in the meeting with my hon. Friend the Minister for Industry, can further discuss how we can take advantage of all that Cornwall has to offer on that front.

The county is perfectly placed to take advantage because of its strong mining heritage—I was interested to hear what my hon. Friend the Member for Truro and Falmouth said about the potential for reopening tin mines—as well as a growing supply chain, skilled workforce and supportive local government. It has the support of national Government too. In 2023, the UK Infrastructure Bank’s first equity deal was an equity investment of approximately £24 million to support Cornish Lithium in the development of the UK’s critical minerals supply chain.

One of the most exciting areas with huge potential is the floating offshore wind that my hon. Friend the Member for Truro and Falmouth talked about, which would enable turbines to be set up where the seabed is too deep for traditional fixed-bottom turbines. A new report from the floating offshore wind taskforce says that the UK’s floating wind industry will be able to support 97,000 jobs by 2050, contributing £47 billion to our economy, and we want Cornwall to have a proper stake in that via the Celtic sea.

I reassure Members present that we want to do all we can to support floating wind infrastructure and supply chains to develop the Celtic sea, to ensure that we get the floating wind pipeline built and bring jobs and growth to the area. As part of leasing round 5, the Crown Estate has launched a £10 million supply chain accelerator fund, focused on capturing some of the economic opportunities identified by the Celtic sea blueprint. A further £40 million has been earmarked, which could be deployed on further opportunities nationally.

More broadly speaking, Members present will know that last week, the Chancellor announced that the UK Infrastructure Bank is becoming the national wealth fund. Capitalised with £27.8 billion, it will have additional financial capacity and an enhanced risk budget, as well as an expanded remit beyond infrastructure in support of the Government’s industrial strategy. At least £5.8 billion of the national wealth fund’s capital will focus on priority sectors, including ports infrastructure, which I am sure my hon. Friend the Member for Truro and Falmouth will be pleased to hear.

Also last week, we published in a Green Paper our vision for a modern industrial strategy—Invest 2035. That is a credible 10-year plan to deliver the certainty and stability that businesses need to invest in high-growth sectors. It will help us create a pro-business environment and support high-potential clusters across the country. It will channel support to eight growth-driving sectors, including clean energy industries, and it will support those sectors to create high-quality, well paid jobs across the country, backed by employment rights fit for a modern economy.

If the plan is to be a success, it needs to be designed and implemented in lockstep with local and regional leaders. That is particularly important in places such as Cornwall, where we are looking at reindustrialisation to an extent, rather than building on current industrial clusters. We will explore how to build on existing place-based initiatives, how to create the best pro-business environment possible in city regions and high-potential clusters, and how to identify, select and intervene in industrial sites to make them magnets for globally mobile investment.

As I said, unlocking Cornwall’s potential is slightly different from going into other areas. That is absolutely key. Planning was mentioned; we must undo some of the blockages in the planning system. In relation to the grid, I very much remember, from when I visited, the knock-on impact of the fact that the transmission line goes only as far as Indian Queens. Until we create the grid infrastructure to cover the right areas and provide sufficient capacity, we cannot deliver on Cornwall’s potential. I think that one of the things holding the Eden Project back with its geothermal work was that it could not get that broader grid connection. The former chief executive of the Climate Change Committee, Chris Stark, has been put in charge of the mission board, and one of his key tasks is to bring in a more strategic approach to grid planning, speed it up and stop those blockages that mean that projects just do not get off the ground because they are stuck in that system.

Skills are also a very important issue, on which I hope we can have continued engagement. I think I am due to meet my hon. Friend the Member for Truro and Falmouth next week to follow up on some of these issues. I want to reassure her and colleagues that our doors are always open, in terms of discussing these things, and I will return to my original point that I share the excitement that Cornwall has huge potential. I think we want a more balanced economy—

[Perran Moon]

Looking at Cornwall, we have mentioned floating offshore wind, onshore wind, geothermal, tidal, solar, lithium, tin and manganese. Can the Minister name anywhere else in the UK where there is such a distillation of critical minerals and renewable energy opportunities? I am very excited by what she said about the cluster concept. Would not Cornwall be an ideal place to be an official cluster for renewables and critical minerals?

[Kerry McCarthy]

I am not sure that we quite have an official badge of cluster; we just have clusters, but yes, I think Cornwall is different in terms of the geography and the current use of the land and we have to approach it in a sensitive way, and one in which we might not have to approach areas that currently are perhaps transitioning from traditional fossil fuel industries to the clean industries of the future. This area is bringing something that, to an extent, is genuinely buried in the land—the industrial heritage there. It has so much potential. The question is how we can work across Departments, starting with my own, DESNZ, but also bringing in other Departments that can unlock that potential. I am sure that the brilliant advocates that there are in the region will all be pushing, and I really hope that we can see swift progress, because clean power by 2030 is such an important part of the Government’s mission and I do not think we can do it without Cornwall playing its part.

Question put and agreed to.
