Tata Steel’s £1.25bn plan to modernise its Port Talbot plant with a new electric arc furnace has been delayed by up to a year due to challenges in securing sufficient electricity supply, casting doubt on the project’s timeline for decarbonisation.
Tata Steel’s transition at Port Talbot has hit another setback, with the company saying its new electric arc furnace could now be delayed by as much as a year because of problems securing enough electricity for the site.
The £1.25bn furnace, backed by £500m from the UK Government, is meant to replace the plant’s old blast-furnace route and underpin Tata’s shift to lower-carbon steelmaking in south Wales. The project was approved in February 2025 and had been expected to be operational by the end of 2027, but that timetable now looks increasingly uncertain.
Koushik Chatterjee, Tata Steel’s chief financial officer, said the delay linked to power connectivity had originally been put at around 18 months, but had already been reduced to 12 months. He said the company was working with National Grid, the electricity system operator and the UK Government to narrow that further.
“Securing access to high-power electricity is critical for our planned transition,” he said, adding that National Grid had formally warned the company its connectivity work was behind schedule.
Tata said it still hoped to bring parts of the system into use early enough to carry out trials and preparatory work before a full grid connection is ready, allowing it to compress the ramp-up once power is available. Chief executive T.V. Narendran has said the company wants at least one connection line in place as soon as the plant is ready so testing can begin rather than leaving equipment idle.
The grid upgrade needed for the furnace is substantial. National Grid is building a new substation at Margam, while also delivering a second 275kV substation on Tata’s Port Talbot site. That work requires new transformers and a 2km underground cable linking the two locations. Industry reports have suggested difficult ground conditions, together with environmental and planning issues, have complicated delivery.
Despite the setback, Tata said construction remains under way and that major components, including the furnace shells, tilting platform and Consteel conveyor, are due to begin shipping soon. A National Grid spokesperson said the connection project is progressing and that the company remains committed to delivering it safely and quickly.
The Port Talbot overhaul is one of the most closely watched industrial decarbonisation projects in Britain. Tata says the furnace will cut site emissions by about 90% and create a more financially sustainable future for the steelworks, which has suffered heavy losses for years. The company has also said that 2,162 people left the business between September 2024 and the end of July 2025, following the closure of the final blast furnace last year.
The shutdown of primary steelmaking at Port Talbot marked the end of more than a century of blast-furnace production in Wales. The site is now being reconfigured around recycled scrap steel, with the new furnace central to Tata’s plan to stay competitive while meeting stricter climate expectations.

- https://www.itv.com/news/wales/2026-06-08/tata-steel-expect-delay-to-new-arc-furnace-due-to-electricity-supply-issue – Tata Steel has announced a potential delay of up to 12 months in the operation of its new Electric Arc Furnace (EAF) at the Port Talbot site due to electricity supply issues. The £1.25 billion project aims to replace traditional blast furnaces with a more environmentally friendly steelmaking process. The company is collaborating with the National Grid and the UK Government to resolve the delays and is optimistic about reducing the delay period. The EAF is expected to be operational by the end of 2027, but the timeline may be extended due to these challenges.

The project, led by contractor Sir Robert McAlpine, is central to Tata’s transition to lower-carbon steelmaking. National Grid is constructing new substations and infrastructure to supply the necessary power, but issues with ground conditions and planning have caused setbacks. Despite these challenges, construction of the EAF and associated facilities continues, with the project expected to be completed in 2027.

The £1.25 billion investment aims to replace traditional blast furnaces with a more sustainable steelmaking process, reducing CO2 emissions by 90%. Supported by £500 million from the UK Government, the project is expected to preserve 5,000 jobs and secure high-quality steel production in the region. Construction is set to begin this summer, with the EAF operational by the end of 2027.
