ABB announced recently that it has received three separate orders totalling$25 million to install flexible AC transmission systems (FACTS) for utilities located in the United States and Australia.
One contract, valued at approximately $13 million, was awarded by the Australian utility, TransGrid, for a static var compensator (SVC) for the 330 kV AC interconnection between New South Wales (NSW) and Queensland.
The latest SVC, scheduled for completion in July 2004, will be installed at the Sydney West substation in order to provide rapid voltage support to the transmission system supplying Sydney and New South Wales, particularly during network contingencies.
The two US contracts are worth approximately $12 million and are both upgrades of existing series compensation installations. One contract, awarded by Idaho Power, is for the replacement of the main 345 kV system at the Goshen substation in Idaho.
The other contract was received from Nevada Power Company for the replacement of an existing installation at the McCullough substation, close to the city of Las Vegas. In addition to equipment delivery and site works of the new installation, this turnkey contract also includes dismantling and disposal of the existing series compensation units.
According to ABB, the common objective of these projects is to enhance, in a cost-effective way, the feed of electrical power into major load areas in the western United States. Both projects are scheduled for completion before the summer peak load of 2004.
Static var compensators and series compensation are part of a group of several technologies commonly referred to as FACTS. These technologies enable power grid owners to increase the capacity of existing transmission networks, while maintaining or improving the operating margins necessary for grid stability.
