Net-Metering (Law on Energy from Renewable Sources)

Updated: 26.09.2017

Author: Jurga Tallat-Kelpšaitė

According to the Law on Energy from Renewable Sources, excess electricity produced by a solar, wind and biomass power installation can be fed into the electricity grid and sent back to the self-generating customers when electricity is not produced (net-metering). Eligible for net-metering are solar, wind and biomass power installations which are operated by individuals (≤ 10 kW) and legal persons (≤ 100 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 solar, wind and biomass power installations operated by individuals (≤ 10 kW) and legal persons (≤ 100 kW) (Chapter III Art. 20 Par. 12 Law on Energy from Renewable Sources).

Wind energy

Eligible are wind power installations operated by individuals (≤ 10 kW) and legal persons (≤ 100 kW) (Chapter III Art. 20 Par. 12 Law on Energy from Renewable Sources).

Solar energy

Eligible are solar power installations operated by individuals (≤ 10 kW) and legal persons (≤ 100 kW) (Chapter III Art. 20 Par. 12 Law on Energy from Renewable Sources).

Biomass

Eligible are biomass power installations operated by individuals (≤ 10 kW) and legal persons (≤ 100 kW) (Chapter III Art. 20 Par. 12 Law on Energy from Renewable Sources).

Addressees

Individuals operating solar, wind or biomass power installations with a capacity up to and including 10 kW and legal persons operating solar, wind or biomass power installations with a capacity of up to and including 100 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, wind and biomass power installation can be fed into the electricity grid and sent back to the self-generating customers when electricity is not produced (net-metering). Eligible for net-metering are solar, wind and biomass power installations operated by individuals (≤ 10 kW) and legal persons (≤ 100 kW). Electric meter records (1) the net amount of the self-consumed electricity and excess electricity exported into the grid per calendar month and (2) the 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 with the electricity supplier in the electricity sales and purchase agreement. 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).
