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.

Buffalo – October 11, 2026 -- National Grid has completed a $32 million modernization of its 110-year-old Perry Street substation in Buffalo, adding 13,200-volt delivery to a site that previously supplied only 4,160 volts. The project is the first of about a dozen substations the utility plans to modernize or rebuild in the coming years.

Perry Street station adds 13,200-volt delivery for Larkinville and First Ward loads

The upgraded facility went online this past summer. It now serves some large loads in the Larkinville and First Ward areas of the city. The original substation was built in 1916, before large electricity loads were commonplace or anticipated.

National Grid Regional Director Ken Kujawa said the renovations responded directly to load growth in those districts, including projects that exceed 1 megawatt.

Tilbury – October 11, 2026 -- National Grid's tunnel boring machine (TBM) Caroline completed a 2.2km drive beneath the River Thames 49 days ahead of the original programme, ending the tunnelling phase of the Grain to Tilbury project, part of The Great Grid Upgrade.

The breakthrough came on Sunday 27 September. Caroline excavated a new high-voltage electricity cable tunnel between Tilbury in Essex and Gravesend in Kent.

Caroline installs more than 10,000 segments across nearly 1,700 rings

The tunnel lining consists of more than 10,000 concrete segments assembled into nearly 1,700 tunnel rings. In her most productive month, Caroline advanced 926 metres and installed 712 lining rings. Peak weekly progress reached 229 metres, and the best single day delivered 41 metres of excavation and 31 installed rings in 24 hours.
