A £12 million upgrade to London’s substations improved power reliability for 57,000 customers using new underground cables, with full completion by summer 2026.
A £12 million upgrade to London’s Wimbledon and Wandsworth substations has improved electricity reliability for over 57,000 customers, replacing aging 132,000-volt power lines with new underground XLPE cables.
One of two eight-kilometre circuits is already active, with the second set for activation by summer 2026.
The project, led by UK Power Networks, enhances grid resilience, reduces outages, and lowers maintenance, supporting the London Power Network’s 99.99% reliability rate.
The investment is part of over £983 million spent on upgrades in the past year.
