About this order

A Multi-Year Tariff (MYT) order determines a regulated entity’s Aggregate Revenue Requirement and tariffs for a full control period — typically five financial years — under Sections 61 and 62 of the Electricity Act, 2003. It usually combines a true-up of past years, a provisional true-up of the most recent year, and projections for each year of the new control period.

This order was issued by the Maharashtra Electricity Regulatory Commission, the electricity regulator for Maharashtra. It relates to the 5th control period, FY2025-26 to FY2029-30.
