As provided in Article Y(5) of ACER’s Recommendation to amend the  Network Code on Requirements for Generators (NC RfG 2.0) , the relevant TSO in coordination with the relevant system operator may specify that type A power park modules shall be capable of providing grid forming capability at the connection point. The Member State or their designated entities may require that the relevant TSO in coordination with the relevant system operator shall specify that type A power park modules shall be capable of providing grid forming capability at the connection point. In this case, the Member State or a designated entity shall develop a roadmap within two years after entry into force of NC RfG 2.0 Regulation in order to assess a roll-out of grid forming capability, that may include impact assessments on oscillations, island mode detection or other technical challenges.

The roadmap will cover type A, B, and C power park modules and electricity storage modules < 10 MW connected below 110 kV, leaving to Member States or a designated entity whether requiring grid forming capability; while mandatory grid forming requirements are applicable at 110 kV and above. Therefore, TSO-DSO coordination would be beneficial to monitor Member States and DSOs activities from system needs and implementation perspectives.​
