There have been no amendments to the two methodologies since as no need to amend has been identified in previous review. This is a joint consultation from all NEMOs.

According to Article 4 (3) for both the HMMCP methodologies respectively, ‘the NEMOs shall, at least every two years, reassess the HMMCP, share this assessment with all market participants and consult it in the relevant stakeholder forums organized in accordance with Article 11 of the CACM Regulation.’
