Pelham, United Kingdom – October 12, 2026 -- National Grid has removed two transformers, each weighing about 180 tonnes, from Pelham Substation, clearing the site for two new 300-tonne quad boosters due between February and April 2027 under its North London Reinforcement (NLR) project.

The units had been in service for around 35 years. Contractors Murphy and Equans worked with National Grid on the removal, with around 20 people involved in planning and execution.

Phased decommissioning took about one month per transformer

Crews dismantled each transformer in a phased, controlled process under approved safety procedures. Before lifting, the team inspected internal components to assess their condition and performance over time. National Grid said the findings will inform the design and management of future transformers.
