New Clean Energy Investment Prospectus for Wales highlights £20bn opportunity

Wales sets out its clean energy investment case

Wales has published a new Clean Energy Investment Prospectus aimed at attracting long term private investment into its energy system. The document brings together a pipeline of projects valued at more than £20 billion over the next decade. Its purpose is simple. It shows where money can be invested and how projects fit with public policy in Wales and across the UK.

For UK businesses, especially SMEs, this matters for practical reasons. Clean energy investment shapes energy prices, grid capacity, local supply chains and tender requirements. When large projects move forward, smaller firms often sit underneath them as contractors, service providers or suppliers. Understanding where government backed investment is going helps you judge future demand and risk.

The Prospectus positions Wales as a focal point for new energy infrastructure. It highlights hydrogen, offshore wind, renewable power, grid upgrades and carbon capture as priority areas. Rather than presenting abstract ambition, it lists named projects and specific locations. That detail is what investors and supply chains usually look for.

Although the document has an international audience, its implications are local. Decisions made now about ports, power networks and industrial clusters will affect operating costs for Welsh firms for decades. English businesses trading with Welsh customers or bidding into UK supply chains will also feel the knock on effects.

This article explains what the Prospectus contains, where the figures come from and why it deserves attention from business owners. We focus on commercial reality rather than policy language.

How the Clean Energy Investment Prospectus came together

The Prospectus was developed by Net Zero Industry Wales, known as NZIW. NZIW is an industry led body supported by the Welsh Government. Recruitment firm Acre worked alongside NZIW on the document.

The starting point was feedback from investors and developers. Many understood that Wales has strong natural resources, but found it hard to navigate projects, permissions and long term plans. Information existed, but it sat across different agencies and strategies. As a result, investment decisions slowed.

The new Prospectus brings together policy context, project information and regional strengths in one place. It is designed to complement the work of Trade and Invest Wales, which promotes inward investment more broadly. Promotion activity linked to the Prospectus is expected to increase through 2026.

Wales has a population of just over 3 million. Despite that size, it has deep industrial experience in heavy manufacturing, energy and engineering. The document stresses this point repeatedly. Clean energy projects need skilled people, not only land and wind.

The Prospectus focuses on several sectors. These include hydrogen production and transport, offshore and onshore wind, solar power, electrification of industry, carbon capture and grid infrastructure. Each of these areas links back to UK net zero policy.

By setting this out in plain terms, the Welsh Government hopes to reduce uncertainty. Investors generally accept construction and market risk. Policy confusion is harder to price.

The investment pipeline and headline figures

The central claim of the Prospectus is that Wales can support more than £20 billion of clean energy investment between now and 2035. This figure reflects projects that are planned, proposed or seeking finance.

Separate analysis by NZIW suggests that the total value of energy and decarbonisation projects could be higher over time. Estimates shared alongside the Prospectus refer to up to £40 billion when indirect activity is included.

In economic terms, NZIW points to around £9 billion in gross value added over ten years from renewables and decarbonisation alone. These figures are not guaranteed outcomes. They are scenario based estimates, but they help frame scale.

The Prospectus also links clean energy investment to job creation. Various programmes together could support up to 20,000 roles by 2030. These include direct construction jobs and longer term operational roles. Supply chain employment is included in the higher estimates.

UK government funding underpins many of the projects listed. This includes support through Contracts for Difference for offshore wind, capital funding for ports and specific pots for hydrogen and carbon capture. According to the Department for Energy Security and Net Zero, these schemes are intended to crowd in private capital.

While investors will test each case on its own merits, the pipeline shows intent. For businesses, intent often shapes procurement plans well before spades hit the ground.

Named projects highlighted in the Prospectus

A feature of the document is its use of named schemes. Rather than generic themes, it points to individual projects that are already moving.

One example is the HyLine Gogledd project. This scheme proposes a hydrogen pipeline linking Deeside and Wrexham. The pipeline would serve industrial users looking to switch from natural gas. Estimates suggest it could deliver more than £2 billion in gross value added over its lifetime.

Another area of focus is data centres linked to energy infrastructure. North Wales is promoted as a potential global scale hub, with very large private investment figures mentioned. In South Wales, proposals are smaller but still significant. These figures reflect ambition rather than final approvals.

The Prospectus also points to the Anglesey Freeport. This site targets low carbon energy, data services and manufacturing. Early funding of £25 million has been allocated, with job creation estimates of around 5,000 roles over time.

Hydrogen features heavily. Statkraft’s Trecwn Green Hydrogen Valley includes a 15 megawatt electrolyser. It has received support from the Net Zero Hydrogen Fund. Smaller commercial users are expected to anchor demand.

Each of these projects carries a different risk profile. For SMEs, the relevance lies in construction services, maintenance, transport, professional advice and long term supply contracts.

The role of offshore wind and the Celtic Sea

Offshore wind is central to the Prospectus. The Celtic Sea off the coast of Wales is highlighted as a major opportunity for floating turbines.

Current estimates suggest that 4.5 gigawatts of floating offshore wind could be operating by 2035. Over the longer term, capacity across the wider basin could reach 20 gigawatts by the mid 2040s.

To put that into commercial context, 4.5 gigawatts is often described as enough to power around four million homes. While household numbers vary, the scale indicates why ports, vessels and grid links matter.

The UK government has already committed £160 million to support ports linked to Celtic Sea development. Supply chains for turbine assembly, anchoring systems and operations are expected to follow.

According to Ofgem, up to £28 billion has been committed across the UK for electricity network upgrades. Parts of this will support offshore wind connections in Wales.

For businesses, offshore wind mainly affects power prices and grid stability in the long term. However, in the short term, it creates local demand for construction and marine services.

Policy alignment with UK net zero programmes

The Prospectus is framed to align closely with UK wide policy. This is deliberate. Investors tend to favour projects that sit comfortably within national schemes.

Several projects in Wales link to carbon capture, usage and storage. The Hanson Padeswood cement works is often cited. It forms part of the UK’s wider carbon capture programme, backed by £20 billion of funding.

Hydrogen policy is another important link. The UK has set a target of 10 gigawatts of low carbon hydrogen production by 2030. Welsh projects such as RES Octopus Green Hydrogen are positioned as contributors.

Nuclear ambitions are also referenced, particularly around Great British Nuclear. While firm plans in Wales are limited, skills and supply chain links are emphasised.

Earlier this year, Contracts for Difference secured 8.4 gigawatts of offshore wind capacity across the UK. Wales participates in these auctions, which provide long term price certainty.

In addition, the Clean Industry Bonus of £544 million aims to attract up to £9 billion in private investment. Welsh suppliers may benefit even where projects are located elsewhere.

Barriers identified within the Welsh system

The Prospectus does not present Wales as friction free. Several structural challenges are acknowledged.

One of the most significant is grid capacity. Without major reinforcement, new generation cannot connect at the scale proposed. A north south electricity connection, often referred to as the PSNC, is seen as critical.

Analysis suggests that this connection could unlock up to 12 gigawatts of floating offshore wind. However, the funding model remains uncertain. Greater Treasury support is being sought.

Planning timescales are another concern. Energy projects often face long approval periods, which carry cost. The Welsh Government has committed to improving processes, but delivery will be tested.

Skills shortages are also raised. While Wales has industrial experience, clean energy requires specialist roles. Training provision will need to keep pace.

For SMEs, these barriers translate into risk. Delays affect cash flow and contract timing. Awareness helps with planning.

What the Prospectus means for operating costs and supply chains

Large scale energy investment eventually feeds into operating costs. New generation and grid capacity can stabilise prices, but only after construction.

In the medium term, businesses may experience more grid works, connection requests and congestion management. These factors can affect expansion plans.

Supply chains are where many SMEs will feel impact first. Major projects typically break work into packages. Welsh based firms may gain an advantage, but only if they are visible and compliant.

Tender requirements are likely to include carbon reporting and social value criteria. This reflects wider UK practice. Firms without basic emissions data may struggle at pre qualification stage.

There may also be indirect effects. Data centres, for example, can increase local power demand. This may influence availability for other users.

Understanding these interactions helps businesses avoid surprises when quoting or investing.

SBS Insight

From an advisory perspective, the Prospectus is not a sales brochure. It is an early signal of where public and private money is likely to go.

We recommend that businesses treat it as a horizon scan. If you supply construction, engineering, professional services or manufacturing, check whether your customers appear in the pipeline.

Energy users should also pay attention. Over time, these investments may change local energy availability and pricing structures. Early awareness supports better procurement decisions. Our guide to energy procurement for UK manufacturers explains how large infrastructure plans affect contracts.

Carbon reporting will increasingly influence access to work. Even small firms may need basic emissions data to remain competitive. Our support for carbon reporting compliance covers what is proportionate for SMEs.

Finally, caution is needed. Not every project will proceed on schedule. Avoid over reliance on a single opportunity. Diversification remains sensible.

Used carefully, the Prospectus provides useful context rather than guarantees.
