A new substation has been switched on to power 20,000 homes in east London.
National Grid's 132 kilovolt Barking substation will help UK Power Networks distribute electricity to homes and businesses, as well as Network Rail to power its electrified lines in the area.
It will also support the ongoing Barking Riverside redevelopment.
Laura Mulcahy, project director at National Grid Electricity Transmission, said: "Our new Barking substation is a crucial upgrade to the electricity network in east London, and will help future proof it as electricity demand in the capital grows."
The substation replaces a previous 132kV facility built in the 1950s, and features 17 bays with room for future upgrades.
Andrew White, programme manager at UK Power Networks, said: "We’re delighted to work with National Grid on this major infrastructure project serving 20,000 locals in Barking and east London.
"This investment will benefit residential and industrial supplies and comes as part of our commitment to reinforcing reliable energy for many years ahead."
