In general, a plant operator is entitled to use of the grid and to the transmission of electricity from renewable sources by the grid operator (art. 25 par. 1; art. 29 par. 1; art. 3 no. 1 Electricity Law). This right shall not apply where the use of the grid poses a risk to the security of the national grid system and where a grid user does not comply with the applicable technical standards. Further, this right shall not apply where the grid operator does not have the necessary grid capacity available (art. 25 par. 2 Electricity Law).

Entitled party: The parties entitled are the plant operators (art. 29 par. 1 letter a) Electricity Law).

Obligated party: The obligated entity is the grid operator (art. 25 par. 1 Electricity Law).


Process flow

The legal obligations are based on statutory law (art. 25, 29 Electricity Law).

Competent authority

Agentia Nationala de Reglementare în Domeniul Energiei – ANRE (Romanian Energy Regulatory Authority)

Obligation to inform

The grid operator is obliged to submit to the grid users all relevant information on his operations related to the management of the grid without discriminating against any grid user. The grid operator is not obliged to provide confidential trade data or confidential information received (art. 45 par. 1 letter e Electricity Law).

Priority to renewable energy

  • Priority to renewable energy
  • Non-discrimination

The generators of electricity from renewable sources are entitled to priority use of the grid. The grid operator may deny use of the grid only in exceptional cases and according to the technical and commercial regulations made by the regulatory authority or if the security of the national energy system is at risk (art. 14 par. 7 Law No. 220/2008 as referred to in art. 1 par. 9 Law No. 134/2012).


According to the transmission system operator, there are no special rules governing curtailment of RES-E plants in particular. General rules for curtailment are prescribed through the Technical Code of transmission network. 

According to ANRE, the commercial code allows RES-E plants to be compensated like conventional plants for the amount of electricity not delivered to the grid, but not for the green certificates income loss due to curtailment.

Distribution of costs


According to the Romanian regulatory authority ISPE, the costs of grid use are passed on to the consumers through the electricity price.

Distribution mechanism

The tariffs for grid use are regulated by ANRE by Ordinance No. 112/2016. The tariffs vary according to the voltage level and the different DSOs (Annex nr. 1 and nr. 2 Ordinance No. 112/2016). According to the Romanian regulatory authority ISPE, the grid operators include the costs of transmitting electricity in their electricity prices.
