Akash Hirpara Maharashtra Electricity Regulatory Commission (MERC) is the state regulator for Maharashtra's electricity sector. Sets tariff orders, net metering rules, and Open Access policies for one of India's largest solar markets.
Key Takeaways
- MERC = Maharashtra state electricity regulator.
- Major Indian solar market regulator.
- MSEDCL is primary DISCOM under MERC.
- Net metering, RPO, Open Access policies for Maharashtra.
What MERC Regulates in Practice
MERC’s authority reaches every major decision point a solar project in Maharashtra has to clear. Its net metering regulations set the eligibility and capacity limits for rooftop solar, and determine how exported units are treated under energy banking — whether surplus generation is netted monthly, annually, or settled at a feed-in rate. Its annual tariff orders fix the wheeling charges, cross-subsidy surcharges, and banking charges that apply to Open Access solar projects, which is why developers pursuing Open Access in Maharashtra also need to track CTU / STU concurrence alongside MERC’s own rulings. MERC also sets the state’s Renewable Purchase Obligation (RPO) targets, which push DISCOMs and other obligated entities to procure a defined share of their power from renewable sources.
In practice, most rooftop and commercial solar applicants never file directly with MERC — they interact with the DISCOM (usually MSEDCL) that implements MERC’s regulations at the interconnection and billing level. Larger commercial or industrial installations that also require electrical inspectorate sign-off typically need CEIG drawings prepared alongside the DISCOM paperwork, since the state electrical inspector’s approval and MERC-governed DISCOM approval are separate steps in the same project.
