FAQs 6

How is grid connection regulated in Romania?

1. Overview Grid connection in Romania is mainly regulated by ANRE Order no. 59/2013 approving the public grid connection regulation (the “ Connection Regulation ”), which has already been amended twice in 2022 (under ANRE Orders no. 17/2022 and 81/2022) and will soon be amended for a third time.

What changes has ANRE made to Romania's grid connection process?

ANRE has also made several immediate changes to Romania’s grid connection processes, including new rules for financial guarantee. Previously required before concluding a connection, the guarantee is now a prerequisite for issuing any new grid connection permit above 1 MW and amounts to 5% of the connection tariff.

How important is grid forming in Romanian power systems?

Grid forming capabilities of such new generators (traditionally grid following technologies) become critical for the future stability of the power system. The article presents several conclusions from power systems where the debate is more advanced and draws some recommendations of the Romanian power system.

Should Romania be prepared for EV grid forming?

Romania should also be prepared for the adoption of rules related to grid forming capabilities of Electric Vehicles (EV) and for performances of the charging stations to serve such EVs (V1G – just absorption from the network, V2G – bidirectional relationship with the grid).

Does Romania have a solar power system synchronously interconnected with the neighboring system?

However, the Romanian power system is synchronously interconnected with the neighboring system and probably the analysis about the weight of invertor based generation would become regional, not only national. A large share of the solar PV capacities will be non-utility, pertaining to prosumers.

What are the main costs of the producer in connection with grid access?

Thus, the main costs of the producer in connection with grid access during the operational phase are related to (i) balancing responsibility; and (ii) adequate maintenance of the internal installations that connect the power plant to the public grid.
