The closure of the final blast furnace at Port Talbot marks a significant moment in the history of British manufacturing.
On 30th September, Tata Steel tapped the last usable liquid from Blast furnace, bringing traditional primary steelmaking in Wales to an end. For years, UK steelmakers have faced some of the highest energy costs in Europe. Combines with global competition, carbon reduction targets and ageing infrastructure, these pressures have contributed to the decision to transition to electric arc furnace (EAF) technology.
While EAFs offers significant carbon savings, they also place increasing reliance on electricity. As more energy intensive industries electrify to meet net-zero targets, questions remain about whether the UK’s power infrastructure can deliver the capacity, affordability and reliability required to support domestic manufacturing.
The challenge is not simply generating enough electricity, it is ensuring industrial users have access to competitively priced power, robust grid connections and long-term energy security. Manufacturers across multiple sectors are also facing growing concerns over energy costs, grid constraints and connection delays, without addressing these issues the UK risks shifting production overseas as opposed to strengthening its industrial base.
From our perspective, if the future of British manufacturing is electric, then the success will depend heavily on resilience, affordability and capacity of the UK’s energy network.
