Ofgem has given its initial approval to a landmark £24bn investment package aimed at transforming Britain’s energy grid and reducing dependence on imported gas. The Office of Gas and Electricity Markets (Ofgem) has provisionally endorsed, subject to consultation, a programme of 80 infrastructure projects focused on new power lines and substations. The investment forms part of the biggest overhaul of the UK’s electricity network since the 1960s. More than £15bn of the proposed funding is earmarked for maintaining the safety and reliability of the UK’s gas transmission and distribution networks. A further £8.9bn will go directly into strengthening the country’s high-voltage electricity grid, with an additional £1.3bn on standby for rapid deployment. This investment marks the first stage of the RIIO-T3 settlement (April 2026 to March 2031) and will kick off a broader, estimated £80bn infrastructure programme designed to modernise the energy grid. The plan includes upgrading over 4,400 km of overhead lines and adding 3,500 km of new circuits, including offshore developments—doubling what has been delivered over the past decade. If completed as expected, the projects will enable the grid to support up to 126 GW of clean, renewable energy by 2030, alongside increased energy storage and flexible technologies. Over the past six months, Ofgem has closely scrutinised the proposals from electricity transmission owners, National Gas, and gas distribution operators. More than £8bn—around 26% of the original proposals—has been trimmed to ensure the plans offer value for money to consumers. Funding allocations include: Jonathan Brearley, Ofgem Chief Executive, commented: “Britain’s dependence on imported gas has left us vulnerable to global market shocks. Without government support, bills could have soared to £4,000 during the energy crisis.This record investment is vital to building a homegrown energy system—one that protects us from price volatility, strengthens our energy security, and helps stabilise bills.” Brearley emphasised that inaction would cost consumers more in the long term. “Doing nothing is not an option. These 80 projects are an insurance policy for the UK’s energy future. We’ve negotiated a fair deal for investors and consumers alike—and we will hold network operators accountable for delivering on time and within budget.” By March 2031, the estimated cost to billpayers is expected to be around £24 a year, or less than 40p per week. This figure does not include the broader cost savings anticipated from a cleaner, more efficient power system. The draft proposals are now open for consultation, with final decisions due by the end of 2025. However, some energy firms have expressed disappointment, arguing that the scale of ambition should have been greater. SSEN Transmission responded: “Ofgem’s draft determination falls short of the ambitious and financeable framework needed to support transformational grid investment. The methodology does not reflect the real, evidence-based costs of delivering a reliable transmission network in northern Scotland.” Despite these concerns, Ofgem remains confident that the proposed investment strikes the right balance between affordability, resilience, and long-term sustainability.

Balfour Beatty has been awarded an £833 million contract by Technip Energies to deliver the Net Zero Teesside Power project—set to become the world’s first gas-fired power station equipped with full-scale carbon capture and storage (CCS) technology. The landmark onshore development will include power generation, carbon capture, and compression facilities. Balfour Beatty will work in collaboration with Technip Energies and GE Vernova, supported by technology partner Shell Catalysts & Technologies, to construct a state-of-the-art combined cycle gas turbine (CCGT) power plant. The project is led by Net Zero Teesside Power, a joint venture between energy giants BP and Equinor. In addition to the main power station, Balfour Beatty will construct a post-combustion carbon capture system capable of removing up to two million tonnes of CO₂ per year. Once captured, the carbon will be compressed and transported via an offshore pipeline for permanent storage beneath the North Sea by the Northern Endurance Partnership—a joint venture involving BP, Equinor, and TotalEnergies. When completed, the power station is expected to generate up to 742 megawatts of low-carbon electricity—enough to meet the average annual energy needs of over one million UK homes. Leo Quinn, Group Chief Executive at Balfour Beatty, said: “Net Zero Teesside Power is an ambitious and pioneering scheme, forging the path towards sustainable infrastructure and establishing the UK as a global leader in clean energy innovation. The project will not only be instrumental in achieving net zero targets but will also stimulate economic growth across the North East, creating thousands of jobs both during construction and for the long term.” This major contract follows the UK Government’s announcement in October 2024 of a £21.7 billion funding commitment for carbon capture and storage projects in the energy, industrial, and hydrogen sectors. Net Zero Teesside Power and the Northern Endurance Partnership received final investment approval in December 2024, paving the way for delivery of this transformative infrastructure.

Murphy has been awarded the largest substation project currently underway in the UK, following a multimillion-pound contract win from National Grid Electricity Transmission (NGET). The project involves the construction of a major new substation at Uxbridge Moor in Buckinghamshire, adjacent to NGET’s existing Iver substation. The new infrastructure is set to play a key role in meeting the growing demand for electricity in west London and will enable new customers to be connected to the national grid. Leveraging its in-house capabilities and direct delivery model, Murphy will carry out the full range of works at the new substation. This includes the construction of both a 400kV and a 132kV substation, underground cabling, ancillary buildings, and modification works to the existing 400kV overhead line network. The 132kV substation will be connected via underground cables. The project also includes major civil works, such as the development of a 1.2km raised access road from the A412 and a new road bridge over the River Alder Bourne, further enhancing site accessibility. A key feature of the project is its use of gas-insulated substation technology, which allows for a significantly smaller site footprint—up to 70% less than a conventional substation. This will help minimise environmental impact and disruption to the surrounding area. Liam Corr, Managing Director of Energy at Murphy, said: “Since 1951 Murphy has been a leading provider of innovative and integrated energy solutions – today we support groundbreaking transmission and distribution projects across the four countries in which we work. “We are proud to be delivering this project in the UK’s capital and building on our strong working relationship with National Grid to help to ensure energy security for decades to come.” Building, Design & Construction Magazine | The Choice of Industry Professionals

RSK Group is continuing to support major UK carbon capture and storage (CCS) projects with eight RSK businesses appointed to contribute to the delivery of CO₂ transportation and storage infrastructure designed to facilitate the HyNet CO₂ pipeline. The RSK businesses have been appointed by United Living Group. Its subsidiary, United Living Energy Limited, part of its infrastructure services business (ULIS), has been selected by Liverpool Bay CCS Limited (LBCCS), a member of the global energy tech company Eni, as one of the primary contractors to deliver CO₂ transportation and storage (T&S) infrastructure. The ULIS project is worth approximately £250 million over a three-year period and will create 300 roles across the supply chain. United Living has said that the facility will be instrumental in enabling the landmark HyNet CO₂ pipeline, which aims to unlock a low carbon economy for North West England and North Wales. The pipeline will be the first step in unlocking the benefits and ambitions of the wider HyNet North West project and achieving the UK’s net zero target by 2050. The project comprises 34 km of new pipeline (with the additional repurposing of an existing 24 km) running from Ince, Cheshire, near RSK’s head office at Helsby, to Point of Ayr in North Wales. RSK’s support of this project follows the recent completion of another carbon capture initiative involving 12 group businesses. These RSK companies supported Heidelberg Materials UK’s successful planning application for the company’s Padeswood CCS project in North Wales – the first carbon capture enabled cement works in the UK. Speaking about the new Liverpool Bay CCS project, RSK Environment Director Rob Domeney explained that the HyNet CO₂ pipeline would take CO₂ captured by industrial emitters across the region and transport it through new and repurposed infrastructure to permanent storage in depleted natural gas reservoirs under the seabed in Liverpool Bay. RSK’s work began in September 2024 and is expected to continue until the completion of construction in June 2027. Rob said: “This project is incredibly exciting for RSK. The group has been working on pipeline and related projects for more than 30 years and has a long history of working at sites across the North West, including at Protos Ince, Stanlow and Padeswood. “We are also contributing to a large number of CCS projects nationwide at all phases of development, from optioneering, feasibility and consents strategy, through consenting, development consent order (DCO) and environmental impact assessment (EIA), to pre-construction and construction support. With this project, we are delivering against a series of deadlines with various DCO requirements and secondary consents, protected species licences and other inputs required before construction can commence. But this is where the teams’ experience really comes into its own and our ability as a group to pool our multidisciplinary resources is very effective.” He confirmed that RSK has been contracted to provide pre-construction and construction environmental support to the project. The wider RSK team includes environmental management staff seconded into the project to help deliver construction environmental management plans and related documentation and secondary consents such as environmental permits and to coordinate the various environmental teams involved. Rob added: “In addition, the project will use more than 50 RSK colleagues across the group to provide ecological surveys, licences and mitigation, archaeological mitigation, advice and support on ground contamination, mining, groundwater and surface water, flood risk planning, landscape design and management and noise, air quality and arboriculture inputs. “RSK Group companies supporting the project include RSK Biocensus (ecology), Headland Archaeology, RSK Geosciences (coal mining, contamination, surface water/groundwater monitoring and materials management plans), LDE (flood risk and hydrology), ADAS (arboriculture and soil survey), Stephenson Halliday (landscape design), RSK Acoustics and Ian Farmer Associates. “The project is in its early stages, with a number of survey teams on-site and ecological and archaeological mitigation in progress, as well as a comprehensive ground investigation programme. Headland Archaeology has 2 teams of archaeologists working on the project and expects its work will involve 276 archaeological trial trenches. Once the initial phases of our work are complete, we look forward to supporting the ULIS team into full construction.” Building, Design & Construction Magazine | The Choice of Industry Professionals
