Environment Management/Energy Efficiency Measures:-
Various Energy efficiency measures are being taken in Metro Railway Kolkata to reduce consumption of conventional energy which in turn contributes in improving our environment as well as helps us to reduce expenditure in electricity bills such as :-
i.Provision of VVVF Drives:-
This initiative has resulted in significant Total 81 large capacity (ranging from 55 to 110 kW) ventilation fan motors are installed in Metro Railway Kolkata for ventilation of 15.67 Km long tunnel section. To improve energy efficiency of these motors, it has been planned to replace the conventional starters with VVVF drives which will provide facility of controlling motor speed as per requirement.
09 Ventilation fan motors have already been provided with VVVF drives. These 9 drives will have the savings of 11.97 lakh kWh energy and 83.97 lakh Rupees per year (approx).
ii. Provision of LED Tube lights:-

iii. Provision of T5 Tube lights:-
10000 T8 Tube lights (36 Watts) has been replaced by T5 Tube lights (28 Watts). This has resulted in energy savings of about 0.5 Million Units and reduction of Rs. 0.34 Crs (approx) in energy bills annually.
iv. Development, production and use of alternative sources of Energy:-
One 10 kWp and one 20kWp Solar power plant has been commissioned in Metro Railway Kolkata. These two plants have generated 3217 kWh energy during 2014-15. One 300 ltrs/day capacity Solar Water Heater has already been commissioned at Noapara Canteen.
