Tata Steel says new £1.25bn furnace may be delayed due to electrical issue
Tata Steel says an electrical connectivity problem could delay its £1.25bn electric furnace in Port Talbot by up to eight months.

Tata Steel warned investors that the Port Talbot electric arc furnace project may slip because the grid connection work is delayed. The company is discussing fixes with National Grid and the UK government as it tries to keep the transition on track.
Tata Steel is building a giant new electric furnace, but the power line it needs is running late. It is like finishing a new kitchen before the electricity is ready to turn on the oven.
Analysis
What happened
Tata Steel says its planned £1.25bn electric arc furnace in Port Talbot may be delayed because of problems with electrical connectivity. The company had expected the new furnace to be operating by the end of 2027.
Why the delay matters
The project is meant to replace the traditional blast furnaces that closed two years ago, a shutdown that came with the loss of 2,000 jobs. Tata says access to high-power electricity is critical to the transition, and that National Grid has formally warned it that the connectivity work is delayed.
What Tata and National Grid say
According to Tata executive director and chief financial officer Koushik Chatterjee, the project is still moving ahead and major demolition work has already been completed. But he told investors the delay could be "between, say, six months to eight months" and possibly longer once the plant is built.
Tata says it is working with the electricity system operator, National Grid, the UK government and its electricity supplier to find ways to reduce the impact on the timetable. In its statement, the company said project timelines are still changing as engineering, construction and infrastructure work progresses, and that it is discussing possible adjustments to commissioning.
National Grid said the work involves two new substations, transformers and 2km of underground cables. It said ground conditions and environmental and planning issues have also contributed to the delay, although it said progress is being made.
The article suggests the project is not being abandoned, but it does show how dependent a major industrial conversion is on grid infrastructure being ready on time.
Key points
- Tata Steel says its £1.25bn Port Talbot electric furnace may be delayed by electrical connectivity issues.
- The company says the delay could be six to eight months, or possibly longer.
- The furnace is intended to replace the blast furnaces that closed two years ago, cutting 2,000 jobs.
- National Grid says the project needs two new substations, transformers and 2km of underground cables.
- Tata says it is working with National Grid, the UK government and others to limit the impact.
If Tata, National Grid and the government resolve the connection issues, the furnace could still move forward safely and as quickly as possible. The company says major demolition work is already done, so the project still has visible momentum.
If the electrical work keeps slipping, commissioning could be pushed back by six to eight months or more. That would delay Tata’s shift away from the old blast furnaces and prolong uncertainty around the Port Talbot transition.
