Faster Planning for Clean Energy Projects in the UK

Environment Agency takes charge of major energy permits

The Department for Environment, Food and Rural Affairs has handed the Environment Agency sole responsibility for environmental permits across major infrastructure projects. This change affects two significant energy developments currently working through the planning system: the Sizewell C nuclear station in Suffolk and several sustainable aviation fuel plants on Teesside.

Previously, developers needed approvals from multiple regulators. Now the Environment Agency acts as the single point of contact for environmental consents on Nationally Significant Infrastructure Projects. The reform aims to cut delays that have historically added months or years to development timelines.

For businesses involved in these supply chains or watching the wider energy transition, this administrative shift carries practical weight. Faster planning means clearer investment timelines. It also signals government intent to accelerate projects that underpin net zero targets and energy security.

Sizewell C moves closer to construction phase

Sizewell C is a proposed nuclear power station on the Suffolk coast. The site would house two European Pressurised Reactors with a combined capacity of 3,200 megawatts. That output could supply around six million homes with low-carbon electricity.

EDF Energy originally developed the project alongside China General Nuclear Power Group. However, the UK government bought out the Chinese stake in late 2022 over security concerns. EDF and the government now jointly own the project.

The Development Consent Order was approved in July 2022 after a lengthy examination process. The application alone ran to more than 50,000 pages when submitted in May 2020. In May 2024, the Office for Nuclear Regulation granted the nuclear site licence. This permit allows safety-related construction to begin, though further consents remain outstanding.

Site preparation work is already underway. Full construction is expected to take between nine and twelve years. The estimated cost stands at £20 billion. The government has committed £1.3 billion in January 2024 and £341 million in August 2023 to support early works and supply chain development.

The Environment Agency issued environmental permits for Sizewell C in March 2023. Under the new arrangements, any additional environmental consents needed during construction will come from the same regulator. This removes the need to coordinate between separate agencies.

Teesside emerges as sustainable aviation fuel cluster

Three separate sustainable aviation fuel projects are advancing on Teesside. Each uses different production methods. Together they position the region as a potential manufacturing hub for low-carbon jet fuel.

Willis Sustainable Fuels received planning approval from Redcar and Cleveland Borough Council in May 2024 for its Carbonshift facility at Teessworks. This Power-to-Liquid refinery will combine industrial waste carbon dioxide with green hydrogen to produce synthetic jet fuel. The process captures emissions that would otherwise be released and converts them into usable fuel.

Lighthouse Green Fuels, led by alfanar, plans a larger waste-to-fuel plant in Billingham. The £1.5 billion facility will process one million tonnes of non-recyclable waste each year. Output is projected at over 165 million litres of sustainable aviation fuel annually. Operations are targeted for 2030.

The Lighthouse project uses gasification technology to break down waste materials. When paired with carbon capture systems, this approach could achieve negative emissions. The facility would remove more carbon than it releases. Statutory consultation for Lighthouse runs until 13 January 2026. A Development Consent Order application will follow in 2026.

Navigator Terminals and alfanar are also developing the UK’s first dedicated sustainable aviation fuel handling terminal on Teesside. Front-end engineering design studies are currently in progress. This infrastructure will be essential for storing and distributing fuel produced at nearby refineries.

Sustainable aviation fuel can reduce lifecycle carbon emissions by up to 80% compared to conventional jet fuel. The exact reduction depends on feedstock and production method. These projects directly support the UK mandate requiring 10% sustainable aviation fuel in the supply mix by 2030.

Regulatory consolidation reduces approval pathways

Historically, major infrastructure developers needed separate environmental permits from different bodies. Water discharge consents might come from one agency. Air quality permits from another. Waste handling approvals from a third. Each application followed its own timeline and assessment process.

This fragmentation created coordination challenges. Delays in one permit stream could halt progress across the entire project. Developers struggled to provide investors with reliable construction timelines. Regulators sometimes duplicated effort or reached conflicting conclusions on related issues.

The Environment Agency now handles all environmental permitting for Nationally Significant Infrastructure Projects. This includes water resources, flood risk, waste management, emissions to air and land, and contaminated land remediation. Developers submit a single integrated application.

For Sizewell C and the Teesside fuel plants, this means one regulator assesses all environmental impacts. The change should compress approval timelines and reduce administrative burden. It also creates clearer accountability when issues arise during construction.

Section 35 directions have already supported applications for some Teesside projects. These ministerial directions fast-track planning submissions deemed nationally significant. Combined with the Environment Agency reforms, the mechanisms aim to keep strategic energy projects moving.

Commercial consequences for energy supply chains

Faster planning affects companies across the energy sector supply chain. Construction firms, equipment manufacturers, and specialist contractors all need visibility on project timelines to allocate resources effectively. Delays create uncertainty that increases costs and complicates workforce planning.

Sizewell C represents a substantial procurement opportunity. Nuclear construction requires thousands of workers and millions of components. The supply chain extends from concrete and steel through to highly specialized reactor components. Smaller firms in Suffolk and surrounding regions may find subcontracting opportunities. However, they will need appropriate quality assurance systems to meet nuclear industry standards.

The sustainable aviation fuel sector is newer. UK manufacturing capacity barely exists at present. Companies that secure positions in the Teesside cluster could establish themselves before the 2030 blending mandate creates guaranteed demand. Airlines will need reliable domestic fuel sources to meet regulatory requirements and customer expectations on emissions.

Energy-intensive manufacturers should watch nuclear developments closely. Sizewell C will add baseload generating capacity at a time when electricity demand is rising. More supply generally puts downward pressure on wholesale prices, though the impact depends on the contract structure used to finance the plant. Businesses with operations in regions served by the National Grid’s southern network may see particular benefit.

Public sector organizations face related considerations. The 2030 net zero targets for central government require carbon reductions across operations. Procurement teams increasingly evaluate suppliers on environmental credentials. Companies that can demonstrate low-carbon energy use in their operations may gain advantages in competitive tenders. Our sustainable procurement support helps suppliers understand these requirements and prepare appropriate evidence.

Workforce availability presents another commercial factor. Both nuclear and sustainable aviation fuel sectors need skilled workers. Competition for engineers, project managers, and technicians will intensify as projects move into construction. Businesses may need to invest in training or recruitment earlier than usual timelines would suggest. SBS Academy training programs cover energy transition skills relevant to these sectors.

What UK businesses should monitor now

• The Environment Agency now issues all environmental permits for Nationally Significant Infrastructure Projects, consolidating approvals previously split across multiple regulators.
• Sizewell C received its nuclear site licence in May 2024 and environmental permits in March 2023, with construction expected to take nine to twelve years at a cost of £20 billion.
• Three sustainable aviation fuel projects on Teesside are at various planning stages, with the Lighthouse facility targeting 165 million litres annual production by 2030.
• The 2030 sustainable aviation fuel mandate requires 10% blending, creating guaranteed demand for domestic production capacity currently being built.
• Nuclear and sustainable aviation fuel supply chains will need thousands of workers and specialized contractors as projects move from planning into construction phases.
• Faster planning timelines improve investment certainty but do not eliminate technical risks, local opposition, or cost control challenges evident in previous major energy projects.

Planning efficiency alone will not guarantee delivery

Streamlined environmental approvals address one bottleneck in infrastructure delivery. They do not solve every challenge these projects face. Sizewell C carries lessons from Hinkley Point C, where costs escalated significantly beyond initial estimates. The strike price agreed for Hinkley electricity raised questions about value for money. Sizewell will likely use a different financing model, but cost control remains a concern.

Local opposition to Sizewell C continues. Residents raise concerns about construction traffic, environmental impact on the Suffolk coast, and long-term waste management. These objections did not prevent the Development Consent Order, but they may create friction during the construction phase. Community relations will require ongoing attention from the developer.

Supply chain capability also matters. The UK nuclear sector has contracted since previous construction programs. Some specialized skills and manufacturing capacity no longer exist domestically. Rebuilding that capability takes time. Similar challenges affect sustainable aviation fuel production, where UK experience is limited.

For the Teesside fuel plants, feedstock availability creates commercial risk. Waste-to-fuel processes need consistent supplies of appropriate non-recyclable material. Power-to-Liquid methods require green hydrogen at scale. The hydrogen economy is still developing. Delays in related infrastructure could affect fuel plant operations.

Market factors will also influence project viability. Sustainable aviation fuel currently costs more than conventional jet fuel. The blending mandate creates demand, but long-term competitiveness depends on production costs falling. Airlines face margin pressure and may resist higher fuel costs. Government support mechanisms will likely remain important for several years.

Businesses evaluating opportunities in these sectors should assess risk carefully. Planning reforms improve one element of project delivery. They do not eliminate technical uncertainty, market volatility, or execution risk. Companies need robust financial planning and realistic timelines. Our compliance and carbon reporting services help businesses understand regulatory requirements as energy sector obligations evolve.

Energy security and industrial policy alignment

These projects sit within a broader government strategy on energy security and decarbonization. Nuclear power provides baseload electricity independent of weather conditions. This complements intermittent renewable sources like wind and solar. As the UK phases out coal and reduces gas use, reliable low-carbon generation becomes more valuable.

Sizewell C also represents an attempt to maintain domestic nuclear skills and supply chains. If the project succeeds, it could enable further reactor construction. The government has expressed interest in expanding nuclear capacity beyond current plans. However, this depends on Sizewell demonstrating better cost control than Hinkley Point C.

Sustainable aviation fuel addresses one of the harder decarbonization challenges. Aviation emissions are difficult to eliminate entirely with current technology. Electric aircraft remain limited to short routes with small passenger numbers. Hydrogen planes face infrastructure and safety hurdles. Sustainable fuel offers a near-term solution using existing aircraft and airports.

Teesside has particular industrial advantages for these projects. The region has a concentration of chemical and process industries. Existing infrastructure for handling industrial gases, waste streams, and energy-intensive manufacturing reduces development costs. The area also faces economic challenges from declining traditional industries. New energy projects offer employment and investment.

Businesses in the Teesside area should consider how these developments might affect local supply chains, property markets, and workforce availability. Companies elsewhere should watch whether the cluster model proves successful. If Teesside establishes itself as a sustainable aviation fuel hub, similar clusters might emerge around other industrial areas with appropriate infrastructure.
