UK Power Networks and National Grid are collaborating to provide the electrical infrastructure that will power thousands of new homes, business growth, and jobs in Biggleswade. The project is part of Central Bedfordshire Council’s initiative to support planned housing growth of around 3,000 homes to the east of the town. A traditional ‘breaking the ground’ event marked work starting on National Grid’s 400kV substation and UK Power Networks’ new grid substation, that will increase power capacity in Biggleswade and help the community move towards a low carbon economy. UK Power Networks and National Grid looked into various technology solutions to deliver the extra 80 megawatts of power required. This detailed assessment included reinforcing existing infrastructure and providing power from other existing substations. These options were discounted because they either failed to meet the power requirements or presented significant and unnecessary engineering and cost difficulties. The National Grid compound for a 400kV substation will measure approximately 150 metres by 130 metres and have a maximum height of 15 metres to connect to the existing overhead power lines. The UK Power Networks compound (Biggleswade East Grid), will have a footprint of approximately 180 metres by 100 metres and a maximum height of nine metres. UK Power Networks project manager Geraint Hancock said: “The start of construction on site is a significant milestone to achieve and is the culmination of 18 months’ of design, surveys, studies and extensive consultation. We have designed a scheme with National Grid that will make the electricity network for Biggleswade fit for the future. Construction works will take around three years to complete with energisation planned in the winter of 2024.” Mark Beasley project director for National Grid said: “We invest around £1 billion each year in the electricity transmission system, delivering the fastest decarbonising electricity network in the world with world-class reliability. We are delighted to be a part of this project, connecting and increasing power capacity to Biggleswade, supporting investment in the town and enabling a secure supply of electricity to the area for the decades to come.” Councillor Richard Wenham, leader of Central Bedfordshire Council, said: “This new electricity substation will meet the growing energy needs of the local community and provide the essential power to support new homes, business opportunities, and jobs. “As we look to do our bit for the planet, and as more people shift to electric vehicles or clean energy to heat their homes, the new substation will help support the important sustainability agenda.” The Council secured £70million of government funding via Homes England Housing Infrastructure Fund for a number of schemes, including this power project.
• National Grid’s Tunnel Boring Machine completes almost 7km journey across South London • 140-tonne machine travelled at depths of up to 50m from Hurst to Eltham • Key moment for £1 billion project to rewire London and prepare it for future electricity demands National Grid team members were celebrating a landmark moment for the London Power Tunnels (LPT) project this week (21st June), as the first of five drives by four tunnel boring machines (TBMs) was completed at Eltham. The 140-tonne TBM, named ‘Christine’ after Christine Townley, the former Executive Director of the Construction Youth Trust, known for her championing of diversity and STEM careers, began its journey at the LPT site in Hurst in July of last year. In total, it has travelled 6.7km underneath London, reaching depths of up to 50m underground in the process. The completion of the drive represents a key moment for the £1 billion project to rewire London and prepare it for future electricity demands as the city continues to grow. LPT will also help provide crucial infrastructure for helping the UK energy sector to reach net-zero targets. Members of the LPT project team gathered at the Eltham site to witness this major milestone and celebrate their achievement. National Grid’s three other TBMs, “Edith”, “Grace”, and “Caroline” continue their tunnelling work deep underground across sites in South London. Speaking at the breakthrough, Gareth Burden, Project Director, London Power Tunnels, National Grid, said: “The completion of Christine’s journey from Hurst to Eltham represents a significant milestone for all of us working on London Power Tunnels today. After close to a year of tunnelling, it is exciting to see the first connection between sites. The team has worked so hard to make this happen, in the face of tough ground conditions.Thanks to HMJV, our engineers, fitters, miners and all else involved. A special thanks also goes to the JGL gangs who put in some hard yards down in the tunnel. It’s great to take a moment to celebrate with them all today and see so many flags and kits proudly on display. LPT is a crucial infrastructure project that will ensure people living in Eltham and Londoners more widely can continue to access safe and reliable electricity supplies. LPT is currently under-budget and on time. The project is part of National Grid’s continued investment across the network – connecting, expanding and maintaining through projects such as Hinkley Connection Project, a £900 million investment to connect low carbon energy to six million homes in the South West. It also has a planned series of investments along the East Coast of England to deliver on the government’s target of 50GW of offshore wind generation by 2030.

IFA2, National Grid’s fourth interconnector, can provide enough clean energy from France to power 1 million British homes, avoiding 1.2 million tonnes (Mt) of CO2 emissions. By 2024, National Grid’s portfolio of interconnectors will provide enough zero carbon energy to power 8 million homes a year, avoiding a total of 100 million tonnes (Mt) of CO2 emissions by 2030. National Grid today launches Britain’s latest interconnector, IFA2. The 149-mile-long power cable runs along the sea bed between Portsmouth, Hampshire in the UK and near Caen, Normandy in France sharing surplus clean energy between the two countries. IFA2 is expected to deliver 1.2% of Britain’s electricity needs, enough to power up to 1 million homes with zero carbon energy. By the end of it’s first year in operation, IFA2 will have helped avoid 1.2 million tonnes (Mt) of CO2 from entering the atmosphere, equivalent to planting 50 million trees. IFA2 is the latest feat of engineering helping to transform Britain’s energy system. In the last decade, Britain’s power grid has decarbonised faster than that of any other developed country with a 64% decline in carbon emissions[1]. Interconnectors have played a critical role in this: every year, National Grid’s three existing interconnectors power the equivalent of 5 million homes with zero carbon energy. This will increase to the equivalent of 8 million homes a year by 2024, as a further three interconnectors are completed, avoiding a total of 100 million tonnes (Mt) CO2 emissions by 2030. That emission reduction equates to taking 2 million cars off the road. Furthermore, as the country’s renewable energy capacity, such as offshore wind, increases, interconnectors will enable Britain to sell any excess renewable energy to neighbouring countries. Despite the pandemic, IFA2 has remained on time and on budget. The 1,000 MW high voltage direct current (HVDC) electrical interconnector is National Grid’s second link to France and is the result of a shared £700 million investment, with partners RTE. UK Energy Minister Kwasi Kwarteng visits IFA2 today as it enters its energisation phase which allows electricity power to run through the cable ready for testing before going live. With the energisation of IFA2, National Grid now has four operational interconnectors – two to France (IFA and IFA2), one to the Netherlands (BritNed) and one to Belgium (Nemo Link). Two further projects are under construction – Norway (North Sea Link, operational 2021) and Denmark (Viking Link, operational 2023). Interconnectors allow the UK to trade clean energy with neighbouring countries, exporting it during times of excess generation, and vice versa. They play a critical role in the UK’s transition to clean energy resources – connecting the UK to hydropower in Norway, wind power in Denmark, and carbon-free nuclear power in France. Jon Butterworth, CEO of National Grid Ventures, said: “While the world is focused on the pandemic and managing the knock-on effects on our lives, we know that progress towards net zero can’t afford to falter and Britain needs to keep up the momentum in reducing harmful carbon emissions. The launch of the IFA2 interconnector, linking France and Britain’s power grids, is an important step in accelerating our progress to a cleaner, greener future.” Kwasi Kwarteng, Minister for Business, Energy and Clean Growth, said: “The opening of this IFA2 interconnector will provide enough clean electricity to power one million British homes so I am delighted to see this joint venture being launched. “Recent government commitments to the development of our offshore wind infrastructure show how the UK is a world leader in low-carbon energy generation and the IFA2 will allow us to share those benefits with our friends and neighbours in France.”
National Grid and its contractors Murphy Eltel Joint Venture have finished building the new 20km high voltage electricity line between Richborough and Canterbury to connect the Nemo Link®, into the UK’s electricity transmission system. The new line, consisting of 60 new pylons is the first to be built in Kent for 25 years. A total of 260km of high voltage cables have now been placed on the pylons and have been tested, paving the way for the final testing and commissioning of the Nemo Link® interconnector, which will allow electricity to flow both ways between the UK and Europe. The Richborough Connection was necessary as there is no high voltage transmission network in the Richborough area to carry electricity from the interconnector. The construction work, carried out by 250 skilled workers at the peak of operations involved more than 6,000 crane lifts to put the new pylons into place for a route that crosses eight roads, three rivers and three rail lines in its journey across the county. Graham Dolamore, Project Director for National Grid said: “The completion of the Richborough Project is a significant milestone in the programme for these two projects which will allow power to flow between Britain and Belgium early next year, providing security of supply and greater opportunities for the UK to trade with wider European energy markets. “I’m proud to have been a part of this project and of the fact that we’ve worked closely with landowners and communities to get the connection built on time and with minimal disruption. It is another demonstration of the crucial role National Grid plays in making sure people across Kent and far beyond have the energy they need, when they need it.” Shane Jestin, Murphy Eltel Construction Director said: “It has been a tough but successful job all round, thanks to the hard work of all those involved. We’ve carried out more than 6,000 lifts and managed to hit challenging project deadlines thanks to a mix of thorough planning and excellent delivery.” More than 750,000 working hours were spent building the new overhead line. In addition, works were also carried out at Canterbury North substation and the new Richborough substation with both substations extended and equipment either installed or upgraded. This work was carried out by ABB and Siemens. Some small-scale works will be carried out over the coming months in preparation for the removal of UK Power Network’s overhead lines in 2020. Work on building the new 20km overhead electricity line between Richborough and Canterbury is now complete Line ready to connect Nemo Link®, a 1000 megawatt undersea interconnector between Belgium and the UK, into the UK’s existing high voltage network when it becomes fully operational in 2019 The two projects together will play an important role in supporting the security of energy supplies across Britain and the continent
Law firm, Bircham Dyson Bell has reported that the UK faces what it describes as a “looming energy crunch” owing to the predicted loss of 25GW of generating capacity by 2030. The report highlighted the closure of 18 major power stations since 2012, representing a reduction of the UK’s total capacity by 14GW to little over 86GW. It also claimed the UK was on course to lose a futher 7GW by 2020 and another 18GW by 2030 if expected closures go ahead. Coal-fired plants at Longannet, Ferrybridge and Rugeley are all due to close this year. Eggborough meanwhile has been temporarily saved from closure after it was contracted into the Supplemental Balancing Reserve (SBR) for the winter of 2016/17. Its future after next year, however, remains uncertain. SBR has also contracted one of the four units at Fiddler’s Ferry although the three remaining units are due to come offline in a few short months. “We have observed increasing concern in recent years that as old electricity generation comes offline, new power generators are not being built at a rate that is keeping pace,” Angus Walker, Head of Government and Infrastructure at Bircham Dyson Bell commented. “Our research establishes the hard facts of how serious the situation is, finding that on current projections this is likely to result in a shortfall between supply and demand – in summary an energy crunch.” Despite documenting the promise of 18 new project which have been granted consent, the law firm’s image of the sector is somewhat bleak. It suggests that, with the upcoming plants having a combined generating capacity of less than 18GW, they will leave National Grid with a deficit of 19GW compared with 2012. Contributors to the the report were quick to point out inconsistent governmental policies as a major cause of the predicted “energy crunch”. Lawrence Slade, Chief Executive of Energy UK insisted the sector was facing real uncertainty and a lack of investment as a result. He claimed: “The cuts made, particularly to renewables, have been drastic and sudden. We need policy certainty and cross-party agreement.” It was just days ago that Energy UK recommended that the government review the Levy Control Framework (LCF) in order to provide clarify to companies and investors, a moved it hoped would inspire new confidence in energy generation.
