Karnataka Electricity Regulatory Commission (KERC) has released the Draft Karnataka Electricity Regulatory Commission (Grid Interactive Distributed Solar Photovoltaic (DSPV) Plants) Regulations, 2026, which mandate installation of batteries for DSPV plants supra 10 kW capableness and let installation of star panels connected gathering facades and radical metering.

The projected regulations volition yet regenerate the existing Rooftop Solar Regulations of 2016. Consumers installing DSPV systems supra 10 kW capableness nether specified metering arrangements volition beryllium required to instal hybrid inverters and artillery vigor retention systems with minimum retention capableness equivalent to 20% of the plant’s procreation potential, arsenic per the draught regulation.

“When batteries are installed, they store the excess powerfulness trapped. Usually less radical enactment astatine location successful the afternoons hence the depletion of vigor is low. Once they instrumentality from location successful the evening, they tin usage powerfulness from batteries alternatively of drafting from the grid. This volition assistance to heighten grid reliability,” said P. Ravikumar, Chairman, KERC.

“Besides, we person allowed radical to instrumentality up Group Net Metering and Virtual Net Metering formally. This volition alteration aggregate consumers to stock the benefits of a communal star installation. This is expected to facilitate wider adoption of star energy, peculiarly successful flat complexes, radical lodging societies and organization campuses,” helium added.

The regulations further let installation of star systems connected gathering facades and elevated structures wrong user premises, thereby providing greater flexibility for star deployment successful municipality areas, sources said.
