For the first time in the living memory of Mumbaiites, the major power utilities servicing the country's commercial capital are likely to impose loadshedding this summer as they haven't been unable to source power to tide over the expected shortage. According to information supplied to the Maharashtra government by the three power supplying agencies, they expect power shortage in the city to be between 900 and 1000 MW. Despite their best efforts to purchase power from other states the power utilities in Mumbai expect at least a 200 MW shortage. The power supply is short across the country and supplies from the ultra mega power plants being commissioned now will not be available for another three years at least, according to analysts. Load shedding or compulsory outage of power happens across Maharashtra though it has never happened in Mumbai. At present, power to Thane, Kalyan and the Vasai-Virar belt on the outskirts of Mumbai is cut off for about three hours every day and for about eight hours one day every week. The Maharashtra government is now leaning on the three utilities to shell out more money for power supplies from other parts of the country so that Mumbai does not face a blackout. Power users may be charged a premium during the summer months, state government sources say. However, a contingency plan put out by some of the utilities indicate that power may be cut off for about 30 minutes every day in Mumbai on a rotation basis.
