The Seeboard Powerlink consortium that will meet London Underground’s electricity needs for the next 30 years will spend £100m upgrading the Tube’s power system over the next five years.
ABB and BICC subsidiary Balfour Kirkpatrick, the electrical and power engineering companies in the consortium, will design, supply, install and commission a central supervisory control and data acquisition system for the network.
They will also install new switchgear, protection and transformer rectifier equipment for 17 Northern Line substations, and signalling power system earth fault detection devices.
The Lots Road power station in Chelsea, which provides most of LUL’s power, will be decommissioned over the next two years.
Seeboard Powerlink will buy the network’s future requirements from electricity suppliers in the competitive market.
However, the consortium will refurbish LUL’s other old power station at Greenwich as an emergency standby plant.
