Tripura Amends Rooftop Solar Rules to Boost Net and Gross Metering Adoption

The Tripura Electricity Regulatory Commission (TERC) has issued the first amendment to its 2024 Grid Interactive Solar Rooftop PV Regulations, revising key clauses on capacity limits, voltage-level eligibility, and billing settlement.

The move follows a representation from Tripura Renewable Energy Development Agency (TREDA) seeking clarity on certain provisions.

Under the amendment, individual net-metered systems are capped at 10 kWp, while group net metering and gross metering projects can go up to 500 kWp and beyond. The Commission has also set clear capacity thresholds across LT, HT, and EHT voltage levels, ranging from 1 kWp at 240V single-phase to above 10 MW at 132 kV.

Billing and energy settlement will now occur quarterly, and the payment mechanism for surplus solar generation has been refined, including a 3.8 units per kW per day cap on eligible generation and credit adjustment provisions for domestic and irrigation consumers.

TERC said the changes aim to promote renewable adoption and ensure fair compensation under both net and gross metering models.
