ABB has won a $34 million (SFr55.76 million) contract to improve the power supply for London subway transport system.
The system is to replace a London power station dating from 1905, the company said in a statement on Monday.
The order is for five static var compensators (SVCs) which control the voltage and stability in power distribution grids. The system will allow London Underground to draw power from more modern power plants, ABB said.
The contract is part of a larger one to overhaul the London area's power distribution network, including cabling and switching. ABB's involvement is as a partner in a consortium that includes British groups, Balfour Kilpatrick and Seeboard Trading.
The first phase of installation is due to be completed in mid-2002, and the second by early 2003, the company said.
Drivers on the London Underground staged a 24-hour strike on Monday in protest at what they say are threats to passenger safety from British government plans to partly privatise the network.
