Mumbai needs to add electricity generation capacity that’s dedicated for its own consumption and reduce dependence on buying power from outside, the Central Electricity Authority team investigating the unprecedented outage across the city and nearby areas in October has recommended.
The CEA said in its report that inadequacy of the transmission network is likely to hamper the security of the Mumbai Metropolitan Region grid in the future.
“Considering the importance of Mumbai system, state transmission utility in line with the future scenario, may suitably plan to maximise embedded generation against the need to import power from grid as a part of long-term plan,” the CEA said, noting that the city’s power units account for only 50% of its peak demand.
The generation capacity available in Mumbai is 1,877 megawatts, of which Tata Power supplies 1,377 MW and Adani Electricity Mumbai supplies 500 MW. That’s half of Mumbai’s peak demand of 3,800 MW.
The panel suggested that to ensure uninterrupted supply, generation sources in Mumbai and adjacent areas should be given “must run” status, which means power distribution companies cannot discontinue or reduce offtake from them.
“Alternatively, similar frameworks like ancillary services available at Centre can be introduced for Mumbai,” it said.
