Order the defendant to bear the costs.

1.

First plea in law, alleging the following errors in law: an error in law by the Board of Appeal in finding that the competence of ACER was not limited by Article 16(13) of the Electricity Regulation and that ACER was effectively competent to adopt policy measures penalising cross-zonal transactions inconsistently with Article 16(13) of Regulation 2019/943 (1); an error in law by the Board of Appeal in disregarding the limits to the competence of ACER resulting from Article 9(11) of Commission Regulation 2015/1222 (2), and an error in law in finding that ACERs competence is ‘conferred’ by Article 6(10) of Regulation 2019/942 (3).

2.

Second plea in law, alleging a failure by the Board of Appeal to provide adequate reasoning to its ruling and thus violation of Article 296 TFEU.

3.

Third plea in law: an error in law that the Board of Appeal found that decomposition of flows does not contradict the definitions of Article 2 of the ACER RDCTCS Methodology.

4.

Fourth plea in law: an error in law that the Board of Appeal found that the decomposition of flows in the ACER RDCTCS Methodology (overestimation of Loop Flow (LF) of importing bidding zones) does not infringe Article 74(6)(c) and (i) of Commission Regulation 2015/1222.

5.

Fifth plea in law: an error in law that the Board of Appeal found that the value of the 10 % Loop Flow (LF) of threshold set by ACER is not too high, which infringes the ‘polluter-pays’ principle, as enshrined in Article 16(13) of Regulation 2019/943.
