In an operations control room in Tata Consultancy Services Kochi campus, 12 employees keep an eye on the IT firm's 100 buildings spread across the country. The control room monitors real-time electricity usage and uses sensors, big data and analytics to tweak chiller and lighting systems to cut wastage on a daily basis.
TCS which employs about 2,50,000 people and expects to add 60,000 more this year -- spends roughly Rs 500 crore on electricity per annum.
To crimp this bill, TCS decided to focus on wastage of electricity. Gopinathan set up a team -- that included executives from the company's corporate technology office, engineering R&D and digital business -- to create a company-wide system to monitor and control electricity wastage. The control room monitors real-time electricity usage and uses sensors, big data and analytics to tweak chiller and lighting systems to cut wastage on a daily basis.
"You can have systems that tell you how much energy you have used. But there is no point knowing that you should have switched off your AC yesterday," Rajesh Gopinathan, chief financial officer of TCS and chief driver of the project, told ET. "This system makes accurate predictions that can be acted upon in real time." He was referring to the TCS designed sensor that would not just keep tabs on electricity consumption of its massive chiller units (that keep campuses cool) but also was capable of executing commands such as powering down these units.
