With the electricity expenses responsible for nearly 15% of the annual ordinary working tariffs, Kolkata Metro is turning to non-conventional sources of power to recede costs. After Mumbai, Kolkata is the most expensive, in context of power tariff charged from the metro. Metro Railway acquires power from CESC at Rs 7.20 per unit and expends 300,000 units per day. One of the reasons for the metro’s nomination for a fare restructuring is the high cost of power in Kolkata.

While Kolkata Metro has started probing into solar energy wherever possible, they are also broaching more efficient equipments to conserve energy. The idea is to reduce expenses and protect the environment. Metro is eco-friendly as it doesn't use fossil fuel directly but power plants do. Two solar plants of 10 and 20 kWp have already been engaged. They have generated 3,217 units of power in 2014-15 and brought down costs by Rs 22,183. Two more 10 kWp solar power plants will be instilled in this financial year. The four plants together will generate 5,500 units resulting in savings of Rs 37,000 annually.

Additionally, larger solar power plants have been planned on roofs. The two 50kWp plants will be installed at Dumdum and Noapara in 2016-17. The metro has also set up a 300 litres/day capacity solar water heater at Noapara carshed. In 2014-15, it saved 3,000 units of power and cut Rs 20,500 from the electricity bill. In this financial year, two more solar water heaters of 500 litres/day capacity each will be commissioned. The three plants will help the metro save 13,000 units of power. The electricity bill is expected to come down by nearly Rs 89,500 after this commissioning.
