Energy storage: rankings published for grid connections of up to 4,700 MW
The decision took effect on publication on 13 November, setting limits of 3,800 MW on the transmission system and 900 MW on the distribution network. Final connection offers are the next stage.
Priority rankings for final grid connection offers to standalone electricity storage plants were published in Government Gazette B 6819 on 13 November 2026. Decision YPEN/GDE/128740/4851 sets the available capacity margins by project group and takes effect on publication.
The overall ceiling for connection offers is 4,700 MW: 3,800 MW on ADMIE’s transmission system and 900 MW on DEDDIE’s distribution network. The rankings are included in the decision’s annexes and concern applications that have already been submitted and assessed.
According to the Ministry of Environment and Energy, 831 applications representing 12,319 MW were submitted. The rankings include projects totalling 7,770.76 MW, exceeding the available ceiling. Inclusion in a ranking therefore does not by itself guarantee a connection offer for every project.
The ministry says the two network operators will issue offers in priority order, subject to technical connection feasibility and concentration limits, until the capacity allocated to each category is filled. This is a permitting and connection stage for investment projects; publication of the rankings does not mean that this capacity has already been built or is operating.
