ABB wins $46 million contracts to reinforce London’s power grid

Substation capacity extension will increase power reliability in capital

Zurich, Switzerland, December 1, 2005 – ABB, the leading power and automation technology group, said today it has won contracts worth a total of $46 million from the U.K.’s National Grid to extend the capacity of two gas insulated substations (GIS) in London. The extension projects are part of National Grid’s ongoing program to increase the reliability of the capital’s power grid.

“ABB’s state of the art power technologies are already helping to ensure reliable power supply in London, including the London underground,” says Peter Smits, head of ABB’s Power Technologies division. “The excellent performance of our technology at the two substations, as well as our ability to meet tight installation and commissioning schedules, helped us to win these additional contracts.”

For a 400-kilovolt (kV) substation in north London, ABB will supply an additional 240-megavolt ampere (MVA) 400/132-kV supergrid transformer, and five GIS switchbays, together with associated cabling and equipment, to be installed within the existing substation building. At a 400-kV substation in west London, ABB will supply a new 400/66-kV supergrid transformer, and carry out 66-kV cabling work.

ABB is responsible for the engineering design and civil works for both substation projects, and will provide a complete installation and commissioning service. ABB can significantly reduce delivery times by using pre-engineered, pre-tested and pre-approved solutions to swiftly integrate the new bays to the existing substation systems.
