ABB has won an order worth around $10 million from Tamil Nadu Transmission Corporation Ltd (TANTRANSCO), the state-owned utility, to build a new gas-insulated substation (GIS) in downtown Chennai, India.
Tamil Nadu is among the most industrialized states in India and Chennai, its capital and the fourth most populous metropolitan area of the country, is considered the biggest industrial and commercial center in southern India.
As part of the turnkey contract, ABB will design, supply, install and commission the substation. Key product supplies include nine bays of 230-kV GIS, power transformers and 23 indoor switchgear units rated at 33 kV. The substations will also be equipped with IEC 61850 based open protection, automation and telecommunication systems as well as ancilliary systems.
“This substation will help to reinforce the grid and enhance power supplies to meet the increasing demand for electricity from residential and commercial consumers as a result of growing urbanization,” said Claudio Facchin, head of ABB’s Power Systems division. “ABB’s compact GIS technology will reduce the substation’s footprint significantly, with due consideration to safety and aesthetics, while ensuring efficiency and reliability.”
The compact substation solution to be deployed in the congested Raja Annamalai Puram area, in the city center, is designed to blend in with the surroundings, and a quick turnaround time will help to minimize inconvenience to the neighboring areas during construction. The project is scheduled to be completed in 2015.
