The Tripura Electricity Regulatory Commission (TERC) has capped the net energy credits at a maximum of 3.8 units per kW per day for solar systems installed by domestic, irrigation, and water works consumers.

The Commission has released the (First Amendment) to the Draft TERC (The Grid Interactive Solar Rooftop Photovoltaic System under Gross/Net Metering) Regulation, 2024. The regulations will be effective from the date of publication in the Tripura Gazette.

The TERC has revised the capacities permitted for gross or net metering.

For individual net metering, the minimum eligible capacity remains 1kW. The maximum capacity allowed has been reduced to 10 kW from the earlier 500 kW.

For multiple net metering points of an individual and for group metering, the minimum allowed capacity is 5 kW, with a maximum of 500 kW. This has been retained without any changes.

For gross metering, the minimum permissible capacity has been increased to >10 kW from the earlier 1 kW. The maximum allowed capacity is reduced to 500 kW and above from 5 MW.

For all cases, the capacity is capped at the contracted load/demand of the consumer.

It has also amended the permissible capacity under different voltage levels as follows:The regulations have also been amended to conduct energy settlement and billing every quarter, rather than monthly.

In instances where energy import or consumption exceeds export within a billing month, prosumers must pay for the net energy at the applicable retail supply tariff determined by TERC. When energy export exceeds import, the distribution company (DISCOM) must compensate the prosumer monthly for the surplus energy at the Feed-in Tariff (FiT) set by the Commission.

The Commission has further clarified that for domestic, irrigation, and water works consumers using solar energy, if the electricity exported to the grid exceeds consumption during a billing period, the excess generation above 100 units will be compensated quarterly by the DISCOM at the FiT determined by the TERC. A generation cap of 3.8 units per kW per day of the approved installed capacity will apply.

Additionally, net energy credits of less than 100 units in any billing period will be carried forward to subsequent periods until a total of 100 units is accumulated. For other consumer categories, the same 3.8 units/kW/day cap applies; however, any surplus energy remaining at the end of the billing period will lapse, and no payment will be made for such excess.

In October 2025, the Ministry of Power urged all states and union territories to scrap separate net-metering contracts for residential rooftop solar consumers and adopt a digital agreement as part of the online application. It also advised utilities to waive various charges for rooftop solar installations, including application and registration fees, net-meter testing fees, and commissioning fees.

In May 2025, the Ministry of New and Renewable Energy clarified that net billing, virtual net metering, and group net metering will also be treated on par with net metering provisions under the Approved List of Models and Manufacturers List-II.
