ABB has won contracts worth a total of $46 million from the UK’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.
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.
