Each prosumer's storage facility must have at least 30% of their PV system’s installed capacity for systems from 3 kW to 200 kW, and at least 50% for systems between 200 kW to 400 kW, according to data posted on the website of the parliament's lower chamber on Wednesday.
The bill was adopted with 180 votes in favour, 33 against and 30 abstentions. It will take effect once promulgated by Romanian president Klaus Iohannis. According to the bill, the power discharged into the grid by prosumers cannot exceed the capacity of their storage facilities.
The Romanian energy system currently operates at a surplus, a trend expected to continue due to low consumption and increasing production capacity from new power plants and prosumers, according to a document accompanying the bill.
Prosumers who fail to install storage facilities by December 31, 2027, will have their connection certificates modified, limiting them to discharging no more than 3 kW into the grid, regardless of the installed capacity of their production units.
Dumitru Chisalita, president of Intelligent Energy Association (AEI), criticized the bill in an article published on Thursday, calling it "abusive and implemented in an amateurish way, only to allow some companies to sell their products". While partial storage of electricity produced by prosumers is an adequate measure, it should have been implemented from the beginning, Chisalita argued.
As of April 30, prosumers have reached an installed capacity of 1,707 MW, which is non-dispatchable, compared to the 1,636 MW of dispatchable photovoltaic capacity, Gabriel Andronache, vice president of Romania's energy regulator, ANRE, said at the World Energy Council's FOREN 2024 renewable energy conference on June 17.
With 129,736 prosumers producing more than the dispatchable amount and creating two consumption peaks and one growing production peak, flattening the prosumers’ production peak is crucial and the government’s decision to finance more storage capacities is timely, Andronache added.
