From lights to air-conditioners and even trains, everything at four underground metro stations will now be operated on solar power. Chennai Metro Rail Limited (CMRL) has commissioned a 103kWp (kilowattpeak) capacity rooftop solar power system to cater to these stations.
The photovoltaic panels have begun generating power at Thirumangalam, Anna Nagar Tower, Anna Nagar East and Shenoy Nagar stations. Through the panels, CMRL will tap around 13,800 units of power every month, and hopes to save Rs 6.3 lakh a year in power costs. By the end of this year, elevated metro stations too will go green, as another 6MW capacity rooftop solar power plant will be installed.
“We have a total installed solar capacity of 1.6MW. Solar power will meet all our technical demand for daily operations in the stations they have been installed,” a metro rail official said. Read more
