Article 2

As it is foreseen that harmonised rules on capacity allocation and balancing will be adopted in 2013, the Commission establishes for the development of harmonised gas rules this annual priority list for 2014:

• interoperability and data exchange rules (Commission adoption phase),

• rules regarding harmonised transmission tariff structures (ENTSOG drafting network code),

• rules regarding an EU-wide market-based approach on the allocation of ‘new build’ gas transmission capacity (drafting of amendment of network code on capacity allocation mechanisms by ACER and ENTSOG as well as including respective tariff rules in the network code on transmission tariff structures),

• rules for trading related to technical and operational provisions of network access services and system balancing (scoping by ACER to identify whether binding EU rules for the further harmonisation of the design of capacity products and contracts as regards firmness, restrictions to allocation or secondary markets are needed, taking into account the implementation of the guideline on congestion management procedures and the network codes on capacity allocation mechanisms and on balancing).
