3. The Commission shall, after consulting ACER, the ENTSO for Gas, the ENNOH, the EU DSO entity and other relevant stakeholders, establish, every three years, a priority list, identifying the areas set out in paragraphs 1 and 2 to be included in the development of network codes.
If the subject matter of the network code is directly related to the operation of the distribution system and not primarily relevant to the transmission system, the Commission may require the EU DSO entity, in cooperation with the ENTSO for Gas, to convene a drafting committee and submit a proposal for a network code to ACER.
