‘Solar energy can help city generate 50% of total use’
Mumbai has a potential of 1,720 MW of solarenergy across rooftops-more than 50% of its peak consumption of about 3,200 MW generated through conventional sources (during summer). While attaining the maximum potential could be impossible at this stage, experts believe realising even 20% of this potential would be good enough for the city. Five organisations got together to assess this potential and put their findings in the report ‘Estimating the Rooftop Solar Potential of Greater Mumbai’, which was released on Monday at IIT-Bombay.
While the major share, according to the report, can come from the rooftops of residential buildings, targeting government buildings should be the first move, say experts. “The easiest way to achieve 20% of the 1,724 MW would be to target government buildings. They generally are directed to reduce energy consumption. Railways too have a reasonably good potential,” said Professor Juzer Vasi, department of electrical energy at IIT-Bombay, and member of the project team.
According to an estimate, the peak demand for Mumbai is expected to increase to 4,108 MW in 2019-20 an alternative source of energy could prove helpful.
