ABB, a power and automation technology group, has bagged orders worth around ₹55 crore from Tamil Nadu Transmission Corporation Ltd (TanTransco) to build a new substation in downtown Chennai.

N Venu, Head, Power Systems, ABB India, said the order is part of a turnkey contract, wherein the company will design, supply, install and commission the substation.

Key product supplies include nine bays of 230 kilovolt (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 ancillary systems.

“ABB India is a proven reliable partner for delivering projects on time. We will establish a substation in a congested city centre so as to limit impact on regular life. Our experience and technologies will help provide safe power to a growing metropolis,” Venu said.

The compact substation solution to be deployed in the congested Raja Annamalai (RA) Puram area, in the city centre, is designed to blend in with the surroundings, and a quick turnaround time will help minimise its impact on the surrounding area during construction. The project is scheduled to be completed in 2015. ABB is the world’s leading supplier of air-insulated, gas-insulated and hybrid substations with voltage levels up to 1,100 kV.

These substations facilitate the efficient and reliable transmission and distribution of electricity with minimum environmental impact, serving utility, industry and commercial customers as well as sectors like railways, urban transportation and renewables.
