DRAFT MAHARASHTRA ELECTRICITY REGULATORY COMMISSION (DEVIATION, SETTLEMENT MECHANISM AND RELATED MATTERS) REGULATIONS, 2025

 

 

MERC has released a draft regulation on DSM & Related matters

Maharashtra Electricity Regulatory Commission Has released a draft copy on Deviation settlement mechanism & related matters. Key highlights for regulation changes by considering demand load & dispatch.

The main agenda being all the users may Intech with their scheduled drawl & injection of electricity into the grid which will facilitate to grid stability & security and make more reliable power flow from generator to consumer.

 

The Regulation shall apply for the entity which are connected through Intra State Power Transmission unit/Distribution electricity system in STOA, MTOA or LTOA transaction including interstate wheeling of power with following conditions

This regulation shall applicable for All General Sellers, Open Access Generators, Bagasse based Co-generation plant /Biomass plants, captive generators (excluding in-situ captive generators) connected to intra-state transmission system.

 

Commission said that these Regulations shall be applicable for Bagasse based Co-Generation plants/Biomass Plants connected to intra-state transmission system having exportable capacity of 5MW or more.

 

Important note is that there no relatability of this regulation with Solar and Wind power generators, it’s cleared that MERC (Forecasting & Scheduling and DSM Settlement for Wind & Solar Generation) Regulation.2028 & amendment thereof shall be continued in force for Wind & Solar power generators.

It is not applicable for MSW/RDF based generating plants also.

Computation of Deviation

Deviation shall be calculated for general sellers as follows:

Deviation-general seller (DGS) (in MWh) = [(Actual injection in MWh) – (Scheduled generation in MWh)].

Deviation-general seller (DGS) (in %) = 100 x [(Actual injection in MWh) – (Scheduled generation in MWh)] / [(Scheduled generation in MWh)].

 

Provided that the Intra-State hydroelectric generating stations are expected to respond to grid frequency changes and inflow fluctuations. They would, therefore, be free to deviate from the given schedule as long as they do not cause a grid constraint. While computing the deviation of intra-state hydro generating stations, the schedule of hydro generating stations shall be replaced with actual generation.
