Rooftop Solar Power plants for Information Technology (IT) Industry | Cognizant Technology Solutions,Coimbatore and Chennai, Tamil Nadu

Cognizant Technology Solutions Corp is an American multinational corporation that provides digital, technology, consulting, and operations services. They have offices all over the world.

Companies ‘Go Green’ initiative program is being led by its Chennai based facility and has already made significant progress in reducing its carbon footprint. The company’s focus is not only to formulate power reduction techniques but also to invest in alternative energy sources.

The solar power plants at the Sholinganallur, Chennai, and Coimbatore facilities have been installed at no investment from Cognizant. The investment has been done by Cleantech Solar – Singapore-based company operating pan Asia specializing in constructing rooftop solar plants for commercial & industrial customers under the Build, Own, Operate, Transfer (BOOT) model (also called the OPEX model).

The company has installed in the solar power plants and is selling back the power generated through the system at a fixed rate for the duration of the power purchase agreement (PPA). The PPA tariff is lower than the per unit cost of power procured from Tamil Nadu State Electricity Board and hence Cognizant can save on its energy consumption cost along with reducing carbon emissions. The operation and maintenance of solar power plants are also taken care of by the investing company.

Sunshot has done complete engineering design, material procurement and installation of the solar power plants.

At the Coimbatore facility of CTS, 749 kWp solar power plant has been installed. It is installed on the RCC rooftop of the office building. The system generates more than 2,900 units of electricity on a bright sunny day. Annually it will generate about 10.8 Lakh units of electricity. This helps in saving more than 900 tonnes of carbon emissions annually.

The plant is synchronised with diesel generator (DG) sets along with Discom power. Thus, during a power failure from Discom, the solar system takes reference voltage from DG sets, this helps in reducing diesel consumption by DG sets.

The Sholinganallur, Chennai facility of CTS runs only on DG sets. CTS doesn’t have a connection from local Discom. Here a 348 kWp solar power plant has been installed on the RCC rooftop of the office building.

And, another 473 kWp solar plant has been constructed on the rooftop of a multi-level-car-park (MLCP) of the building.

the plant generates about 3,300 units of electricity on a bright sunny day.  This helps in reducing about 1,900 liters of diesel consumption each day. Annually the solar power plant will help in reducing more than 3.6 lakh liters of diesel consumption. This will also help in reducing more than 960 tonnes of carbon emission.

Systems in both the cities of Tamil Nadu are monitored through Sunshot’s proprietary online monitoring system. This is used to monitor power generation through solar. It also helps in conducting preventive maintenance activities for solar power plants.
