CHENNAI: Soon, a part of the daily operations at Nanganallur Road and Meenambakkam stations will be on solar power, as Chennai Metro Rail Limited (CMRL) has installed and commissioned a 428KWp solar power plant on the roof of the two elevated stations.
The solar plants, with a capacity to generate around 57,780 units per month, is expected to save metro rail around Rs 26.34 lakh per year.
While a major portion of the operations at the stations is planned to be powered by solar panels in the future, CMRL is also working towards using solar power for operation of trains eventually.
The generated solar power will be utilised for lighting systems and to operate electrical equipment required for the maintenance of the stations. So far, CMRL has a total installed capacity of 4.1 MWp solar power including those installed at its head office in Koyambedu and a few other metro stations.
CMRL had already installed 1 MW solar panels at its depot and 125 kw at its car park area generating a total of 1.35 lakh units a month saving CMRL Rs 21.6 lakh for CMRL on power charges.
Another 2.5 MWp roof top solar power installation is under progress and is expected to be completed by end of this year.
