Rooftop solar system order favours Lumex net metering
Rooftop solar system regulation in Maharashtra has produced an important order for industrial consumers. MERC, in Case No. 245 of 2025 dated 9 June 2026, directed MSEDCL to treat Lumex Industries Limited’s 999kW rooftop solar installation under net metering from April 2025. Rooftop solar system credits had been given at gross-metering rates of Rs. 2.90 and Rs. 2.82 per unit, creating a differential credit issue. EnergylineIndia.com highlights this update for readers tracking Open Access Consumers and State electricity regulator orders. MERC directed both parties to reconcile the differential credit within 30 days, with interest at the Bank Rate. The order matters because Lumex first availed open access in April 2025, and the Commission has tied that period to net-metering treatment. Rooftop solar system users in the industrial category should study this decision closely because metering treatment can materially affect project returns. Rooftop solar system billing disputes often arise when consumers combine rooftop generation with open-access power. Rooftop solar system regulation is becoming more commercially important as industrial users seek lower energy costs.
