MUMBAI: The mercury dipped to record lows on several days this winter, but contrary to expectations, power consumption in the state didn't register a simultaneous fall. Rather, demand in Maharashtra increased by 1193 MW in seven months since the peak of summer. The state consumed 18145 MW of power in December 2011, much more than the 16952 MW in the peak summer month of May 2011. This increase, besides being an indication of growing prosperity, is a warning sign for the critical four months of summer that lie ahead.
