{"target_audience": "b2b", "is_medical": false, "ai_generated_title": "National Grid Advances £1bn South London Rewire, 2GW HVDC Links", "body_html": "<p><strong>United Kingdom -- [CURRENT_DATE] --</strong> National Grid is advancing a portfolio of transmission projects across Britain, led by a seven-year, £1 billion programme to rewire South London through deep underground tunnels. The programme began in Spring 2020. Other projects aim to carry more renewable power from Scotland, the North Sea and East Anglia to demand centres.</p><h5>Two 2GW HVDC links target Scotland-to-England bottlenecks</h5><p>EGL1 is a 2GW high voltage direct current (HVDC) link between the Torness area in East Lothian and Hawthorn Pit in County Durham. EGL2, also rated at 2GW, will run between Peterhead in Aberdeenshire and Drax in North Yorkshire. EGL3 and EGL4 are planned to connect new offshore wind farms. Sea Link, a planned undersea high voltage connection between Suffolk and Kent, is under development.</p><h5>Chesterfield to Willington plan lifts 275kV lines to 400kV capacity</h5><p>The Chesterfield to Willington project proposes uprating existing 275kV overhead lines to carry a 400kV transmission load, with three new substations. It is intended to add capacity between the North and the Midlands. A separate reinforcement is aimed at carrying proposed clean power from East Anglia.</p><p>In Lincolnshire, the Grimsby to Walpole proposal would add a new high voltage overhead line with new pylons and substations. National Grid Electricity Transmission is also investigating sites near Navenby for a substation to connect several proposed solar projects. Carlisle to Newcastle, which would upgrade the link between North West and North East England, is at an early stage.</p><h5>Grain to Tilbury plan would replace the 1960s Thames Cable Tunnel</h5><p>The Grain to Tilbury proposal involves replacing the existing 1960s Thames Cable Tunnel beneath the Thames. National Grid says the Littlebrook substation in Dartford is no longer fit for purpose and needs a new facility. At Bramley substation, it is installing a 400/25kV Supergrid transformer, connected to a new trackside substation, to support Network Rail's decarbonisation.</p><h5>Refurbishment programmes cover lines dating to 1971</h5><p>National Grid is also refurbishing ageing assets. The Drax to Thornton line in Yorkshire has operated since 1971. Work on the 15km Kearsley to Whitegate line, which has 45 pylons, is under way. From October 2022, National Grid and contractor Balfour Beatty are refurbishing a 40km (25-mile) stretch of overhead line starting at Nursling. Works are also planned on Walham to Cilfynydd, Fleet to Lovedean, Penwortham to Daines and Bramford to Braintree to Rayleigh.</p><p>The Tyne crossing project is being run with the North East Combined Authority and Port of Tyne. It aims to remove the restriction posed by overhead lines crossing the river at Wallsend and Jarrow. Under the Visual Impact Provision (VIP) project, a Landscape Enhancement Initiative will use up to £11 million of the Ofgem provision.</p>", "meta_description": "National Grid advances a £1bn South London rewire, two 2GW HVDC links and a 275kV-to-400kV uprating as it expands UK transmission capacity for renewable power.", "seo_keywords": "National Grid, transmission network, HVDC, Eastern Green Link, Sea Link, 400kV uprating, South London rewire, substations, UK grid, offshore wind", "companies": ["National Grid Electricity Transmission", "Balfour Beatty", "Network Rail"], "industries": ["Energy & Environment"], "markets_regions": ["United Kingdom"], "news_type": ["project_announcement", "infrastructure_investment"], "products": [], "themes": ["grid_infrastructure", "energy_transition", "renewable_integration"], "events": [], "cta_text": "See National Grid's project pages for details on individual transmission upgrades", "learn_more": "", "fact_check": {"accuracy_score": 95, "legal_risk": "low", "corrections_made": ["Source text was truncated in places; the Nursling refurbishment end point and the 'VIP' acronym expansion were omitted or kept to what the source states", "Dateline city not stated in source; country used"], "recommendation": "publish"}}
