British trade unions are calling for Tata Steel’s EAF to be connected to the grid as soon as possible

The steel producer and National Grid are exploring options to speed up the work

The British trade unions Community, Unite and GMB have called on the government to intervene to speed up the connection of Tata Steel’s electric arc furnace to the grid in South Wales, according to The Guardian.

In May, the company informed investors that National Grid had announced a six- to eight-month delay in the construction of the relevant grid. Due to unexpected engineering difficulties, this timeframe could be extended to a year.

This delay will exacerbate the challenges facing one of the UK’s most important industrial projects. The companies are exploring options to speed up the connection, including reordering the work and installing a smaller temporary power supply so that Tata Steel can begin testing.

Tata Steel shut down its blast furnaces in Port Talbot in September 2024 to transition to cleaner technologies. The new electric arc furnace was expected to be operational by the end of 2027.

However, National Grid, the company that manages a significant portion of the UK’s electricity infrastructure, stated that grid works had encountered problems, including unsuitable ground conditions, as well as planning and environmental issues. The operator has been repeatedly criticised for the length of time projects awaiting connection have been delayed.

Kushik Chatterjee, Chief Financial Officer of Tata Steel, said that National Grid had initially warned that the delay in electricity supply could last up to 18 months.

National Grid was privatised in 1995 and is listed on the stock exchange, meaning the government has no power to direct its investments.

A Tata Steel spokesperson said the companies were “still discussing potential adjustments to the commissioning schedule”, but had already reached several key milestones during the construction phase.

A National Grid spokesperson, in turn, said the company recognises the importance of this project and is committed to ensuring a safe and timely connection.

“Construction is ongoing, good progress is being made, and we are working constructively with Tata Steel and the government to explore options for accelerating the programme,” he noted.

The National Grid representative added that this is a large-scale, multi-million-pound programme involving complex engineering, taking into account environmental and planning considerations that require careful design and implementation.

It should be noted that part of Tata Steel’s capacity in the UK has been suspended following a fire at the Port Talbot plant.
