Andhra reduces rooftop solar projects' net metering cap

10 Jul 2023 CW Team

The Andhra Pradesh Electricity Regulatory Commission (APERC) has issued the draft ‘Grid Interactive Solar Rooftop Photovoltaic Systems Under Net/Gross Metering Regulations, 2023,’ under which the net metering upper cap for rooftop solar projects has been reduced from 1 MW to 500 kW, and the gross metering upper cap has been increased from 1 MW to 5 MW.

As per Mercom Research, prosumers with a higher contract demand of up to 5 MW have an alternative for moving toward a gross metering mechanism instead of open access. The maximum capacity at a single location has been capped at 5,000 kW under the gross metering arrangement.

The cumulative capacity of all grid-connected rooftop solar systems under net metering and gross metering arrangement connected to a particular distribution transformer should not exceed 80% of its rated capacity. The proposed regulations will apply to all grid-connected rooftop solar systems with or without battery energy storage systems (BESS) installed and commissioned in the areas of the state’s distribution companies.

The capacity of grid-connected rooftop solar systems under net metering or gross metering arrangement to be installed at the premises of any individual prosumer should not be less than 1 kW. Any consumer wishing to install grid-connected rooftop solar systems, with or without BESS, under multiple services of an individual consumer or group net metering framework must ensure that the system’s capacity is at least 5 kW.
