GERC (Grid Interactive Distributed Renewable Energy Sources) Regulations, 2026
Gujarat's regulator has notified a single rulebook for rooftop and other distributed renewable systems, replacing its 2016 net-metering regulations. It offers five metering options, requires battery storage when larger consumers install more capacity than their contract demand, and limits how much exported energy non-residential users can offset.
Why it matters. Sets the economics for rooftop and distributed solar in one of India's largest rooftop markets, with a storage mandate and a tight offset cap for commercial and industrial users.
What changes
- Five arrangements: net metering, net billing, gross metering, group net metering and virtual net metering.
- Net metering and net billing run from 1 kW up to 1,000 kW AC (1,250 kWp DC); gross and virtual net metering go up to 4,000 kW AC.
- Consumers with contract demand above 100 kW who install capacity beyond it must add storage covering at least 50% of the excess, with at least two hours per charge–discharge cycle a day.
- Residential exports are fully offset with no banking charge; any surplus is bought by the discom at Rs 2.25/kWh.
- Non-residential offset is capped at 30% of energy imported in the billing cycle, with banking charges; unused banked energy lapses at the end of the cycle.
- Applies to systems commissioned from notification; owners keep 100% of carbon-credit proceeds.
Who is affected
Gujarat discoms · Rooftop solar consumers · C&I prosumers · Rooftop and BESS installers
