  • The energy accounting and settlement under this arrangement shall be in accordance with Regulation 12.

Net billing arrangement

The solar energy generated by the SPV systems is consumed by the consumer with the surplus, if any, being exported as in case of net-metering arrangements. However under net billing arrangements, the monetary value of the imported energy from the grid is based on the applicable retail tariff. The monetary value of the exported solar energy to the grid is based on feed-in tariff approved by the Commission. The monetary value of the exported energy is deducted from the monetary value of the imported energy to arrive at the net amount to be billed (or credited/carried-over). With the net billing mechanism only a single bi-directional energy meter is needed as is done for net-metering. The consumers may opt for Net Billing arrangement as specified in Regulation 4. The energy accounting and settlement under this arrangement shall be in accordance with Regulation 13.

Gross Metering Arrangement

In case of gross metering, the consumer does not consume the solar power generated in his premise and entire solar generation is fed in to the grid which is billed at the rate of feed-in-tariff approved by the Commission. The total energy imported by the consumer from the grid is billed at retail tariff determined by the Commission. Two separate meters i.e generation meter and the consumer meter shall be used for gross metering at the point of supply.

The consumers may opt for Gross Metering arrangement as specified in Regulation 4 and shall further be restricted to the capacity and network configuration of the electricity system, and the power flows that SPV system may cause. The energy accounting and settlement under this arrangement shall be in accordance with Regulation 14.
