Net-Metering (Law on Energy from Renewable Sources)

Author: Jurga Tallat-Kelpšaitė

According to the Law on Energy from Renewable Sources, excess electricity produced by a solar power installation can be fed into the electricity grid and sent back to self-generating customers when electricity is not produced (net-metering). Eligible for net-metering are residential solar power installations (up to 10kW) and roof-mounted and building-integrated PV systems on/ in the buildings owned or managed by state or local institutions (up to 50 kW). For the self-generated and consumed amount of electricity a self-generating customer is relieved from paying a Public Service Obligation levy. However, he has to pay the fee for the use of electricity grid set by the National Commission for Energy Control and Prices (NCC).

Eligible technologies

Eligible for net-metering are residential solar power installations up to 10 kW and roof-mounted and building-integrated PV systems on/ in the buildings owned or managed by state or local institutions up to 50 kW (Chapter III Art. 20 Par. 12 Law on Energy from Renewable Sources).

Solar energy

Eligible: residential <10 kW and roof-mounted and building-integrated PV systems on/ in the buildings owned or managed by state or local institutions <50 kW (Chapter III Art. 20 Par. 12 Law on Energy from Renewable Sources).

Addressees

Operators of residential PV systems <10 kW and roof-mounted and building-integrated PV systems on/ in the buildings owned or managed by state or local institutions <50 kW (Chapter III Art. 20 Par. 12 Law on Energy from Renewable Sources).

Procedure

Process flow

According to the Law on Energy from Renewable Sources, excess electricity produced by a solar power installation can be fed into the electricity grid and sent back to self-generating customers when electricity is not produced (net-metering). Eligible for net-metering are residential solar power installations up to 10kW and roof-mounted and building-integrated PV systems on/ in the buildings owned or managed by state or local institutions up to 50 kW. Electric meter records (1) net amount of the self-consumed electricity and excess electricity exported into the grid per calendar month (2) net amount of the self-consumed electricity and excess electricity exported into the grid from 1 April of the current year until 31 March of the following year (accumulation period). If in a current calendar month, the amount of electricity generated and fed into the grid exceeds the amount of electricity used, the unused amount of energy from the preceding month is transferred into to the following month, as an amount, which is accumulated in the accumulation period. If in a current calendar month, a self-generating customer produces less energy than consumes, the difference between electricity consumed and fed into the grid resulting in a current calendar month is subtracted from the accumulated amount of the electricity fed into the grid over the accumulation period. If at the end of a calendar month the self-generating customer consumed more electricity than generated and fed into the grid, for this difference he pays the electricity price agreed in the electricity sales and purchase agreement with the electricity supplier. The surplus of the preceding year of electricity produced by a self-generating customer is not transferred to the following year and the self-generating customer is not paid for it (Chapter III Art. 20 Par. 12 Law on Energy from Renewable Sources).

Distribution of costs

Plant operator

For the self-generated and consumed amount of electricity a self-generating customer is relieved from paying a Public Service Obligation levy. However, he has to pay the fee for the use of electricity grid set by the National Commission for Energy Control and Prices (Chapter III Art. 20 Par. 13 Law on Energy from Renewable Sources).
