The use of the land near Bridgwater, Somerset, to construct the future has an almost poetic quality. This area of rural England was home to a royal ordnance factory for many years; it was a place meant to be destroyed. A business supported by the Tata Group is currently attempting to produce the batteries that could power Britain’s electric future on the same 616 acres. It’s a major reversal of intent. It’s not going as planned, like most ambitious endeavors.
A contractor change is the most recent development in the construction story of the Somerset EV battery plant. Agratas, the Tata-owned company commissioning the gigafactory, has split from Sir Robert McAlpine, the company hired to construct what will be the biggest EV battery facility in the UK. It was a mutual decision, according to both parties. As is customary in these circumstances, the language was cautious. According to Sir Robert McAlpine, the construction’s initial phase was “successfully completed.” To move the project forward, according to Agratas, a “different construction delivery model” was required. Neither of them said anything that seemed especially illuminating, which says something in and of itself.
TSL will now assume the role of principal contractor. According to McAlpine’s spokesperson, the transition is intended to be orderly and seamless. It remains to be seen if that holds true in reality. Mid-build handoffs don’t always work well for large construction projects, and this isn’t a tiny warehouse on the outskirts of a business park. Built on a brownfield site with its own logistical burden, this industrial project employed about 2,000 people at its height this year.
Already, the timeline has slipped. The factory was initially scheduled to open in 2026 by Agratas. That was shifted to 2027, and it is currently settled on late 2027 for the time being. It’s important to remember that schedule modifications are common for projects this size. Tesla’s Nevada Gigafactory was years behind schedule. Similar delays occurred at Samsung’s chip plant in Taylor, Texas. At least in the beginning, the ambition usually surpasses the execution. However, every delay increases uncertainty, and supply chain partners and investors detest uncertainty the most.

The job numbers associated with this project continue to be compelling. According to Agratas, 1,500 operational positions will become available in 2027, with the possibility of 4,000 positions overall as the factory grows throughout the entire site. It is difficult to overestimate the impact that such jobs would have on Somerset’s economy, which has not historically been a center of advanced manufacturing. Large manufacturing facilities often create ecosystems around their towns, including suppliers, logistics firms, canteens, and housing demand. If the factory fills to capacity, there could be a significant knock-on effect.
All of this is part of a larger narrative. Bridgnorth Aluminium, a Shropshire company, recently announced a five-year contract with Lotte Aluminium Materials USA to supply aluminium for EV batteries in the United States. Since January, the company has added 40 new employees and resumed round-the-clock production. It’s a small piece of information, but it suggests something: even as the major projects encounter difficulties, the supply chain for electric vehicles is starting to take shape in Britain, piece by piece.
The construction of the Somerset EV battery plant is still ongoing. After laying the foundation and raising the steel, a new contractor is now taking over to move the project forward. It’s actually unclear if late 2027 will remain the opening date. However, the fundamental reasoning behind the project remains the same: Jaguar Land Rover needs a local supply chain, Britain needs domestic battery capacity, and Tata Group has the funding to make it happen. The principles remain the same. Stress testing is being done on the execution. And that’s the part that’s worth watching the most.
