Utilities providing electricity to the city have pleaded for a hike in tariffs ranging from 17 per cent to 51 per cent for the next financial year.

Reliance Infrastructure, Tata Power and BEST have sent their annual revenue requirement details to the Maharashtra Electricity Regulatory Commission (MERC) over the last week and released advertisements to that effect. It is customary on part of power companies to make a representation on their proposed power tariff in February.
