Tata Steel has confirmed that the commissioning of its new £1.25 billion furnace at the Port Talbot plant in South Wales will be delayed by a critical electrical fault. The company described the issue as a significant setback to its modernisation programme, which is central to the UK’s plan for decarbonising the steel industry.
The fault was identified during pre-operational testing of the electric arc furnace, which is designed to replace traditional blast furnaces and reduce carbon emissions by up to 80 per cent. Engineers are currently assessing the scope of the repairs, but Tata Steel has declined to specify a revised timeline for the furnace’s activation.
The delay comes at a sensitive moment for the UK steel sector, which has been under pressure from global overcapacity and rising energy costs. The government had committed £500 million in subsidies to support the transition, contingent on Tata Steel maintaining production levels and safeguarding jobs.
Union leaders expressed frustration, warning that the prolonged shutdown of the old blast furnaces has already resulted in temporary layoffs. The Community Union called for immediate talks with management to secure employment guarantees.
Tata Steel stated that safety remains the priority and that the electrical fault posed no risk to personnel or the surrounding community. The company is in discussions with contractors and equipment suppliers to expedite the repair process.
The Port Talbot plant employs approximately 4,000 workers, with thousands more in the supply chain. The delayed furnace threatens to undermine the region’s economic recovery and raise questions about the viability of the government’s net-zero industrial strategy.
A spokesperson for the Department for Business and Trade said the government expects Tata Steel to deliver on its commitments and is monitoring the situation closely.
