CHENNAI: The Electricity Regulatory Commission has issued new guidelines and a consultative paper on ‘Generic Tariff order for Grid Interactive Solar Photovoltaic Energy Generating Systems,’ proposing a gross metering system to allow consumers to sell power generated through solar plants along with time of-the-day solar energy feed-in tariffs.
The proposed tariffs range between Rs 3.99 per kWh for solar system capacities up to 10 kw and Rs 3.12 per kWh for solar system capacities from 501KW to 999 kW. The tariff determined will apply to grid connected solar energy systems for all consumer categories, TNERC proposed. It proposed generic tariffs for rooftop solar systems in TN with net metering and gross metering facilities and has invited submissions and objections from the stakeholders by September 1 in its website.
The Tamil Nadu Solar Energy Policy 2019 set a rooftop solar target of 3,600 MW by 2023. As of March 31, this year, the State’s installed rooftop solar plant capacity stood at 325 MW, which means only 9.03 % of the target has been achieved. With the proposed revision of norms of gross metering, net metering and net feed-in mechanism the tariff applicable to the exported energy has been delinked from consumer tariffs. In net metering, the exported solar power is adjusted in the electricity bill against the energy consumed.
“Consumers may benefit from self-consumption of solar energy, depending on consumer retail tariff, the quantity of solar energy self-consumption and the times of the day of self-consumption. Daytime energy demand is different for each consumer and changes throughout the year,” it stated The TNERC also proposes a time of-day premium tariff during high demand periods, to promote and incentivise investments in solar energy storage systems. The ToD solar energy feed-in tariffs shall apply for evening peak hours (6pm-9pm) or such other time slots as the TNERC may decide.
