Chennai Metro Rail Limited (CMRL) has commissioned a solar power plant with a capacity of 410 KWp at the maintenance depot in Koyambedu. The plant can generate around 55,350 units a month that can save CMRL nearly Rs 15 lakh a year. With this, CMRL has a solar power plant in various locations with a total installed capacity of 2.1 MW.
Metro will use the solar power for the maintenance of trains at the depot and for the administrative building. CMRL has installed the photovoltaic panel on the rooftop and the ground area of the depot. Another 5.5 MW rooftop solar power installation is under progress which will be completed by end of 2018. CMRL has already installed a 1 MW solar power plant at the depot in Koyambedu and another 125 KWp at its headquarters.
CMRL has also commisioned Solar PV panels with a capacity of 103 KWp in four metro UG stations- Thirumangalam, Anna Nagar East, Anna Nagar Tower and Shenoy Nagar. These panels will generate 13,800 units every day which will save CMRL Rs 6.3 lakh a year.
Railways can lead India as a major solar power in the transportation sector
Transportation sector in India is slow towards adopting renewable energy but Indian Railway can certainly lead the march. The railway happens to be a major guzzler of diesel whose prices have soared in the recent time. By increasingly using rooftop solar plants across its premises it is not only saving its expenses on electricity bill but also hedging itself against the fuel price volatility. Not to mention the electricity demand it will be able to meet using clean energy.
Indian Railway is an energy-intensive consumer. Regulators should relax certain norms for them to use solar power on their premises.
