Article 3 6.

Projects of common interest that fall under the energy infrastructure categories set out in point (1)(a), (b), (c), (d) and (f) of Annex II to this Regulation shall become an integral part of the relevant regional investment plans under Article 34 of Regulation (EU) 2019/943 and of the relevant national ten-year network development plans under Article 51 of Directive (EU) 2019/944 and other national infrastructure plans, as appropriate. Those projects of common interest shall be conferred the highest possible priority within each of those plans. This paragraph shall not apply to competing projects, projects that have not reached a sufficient degree of maturity to provide a project-specific cost-benefit analysis as referred to in Section 2, point (1)(d), of Annex III or projects of mutual interest.
