ARTICLE 3(5) AND 3(23)

REGULATORY PERIOD AND TARIFF PERIOD

Responsibility: subject to national decision based on Article 41(6)(a) of the Gas Directive

The TAR NC distinguishes between the concepts of ‘regulatory period’ and ‘tariff period’. The regulatory period is a more general concept, for which ‘the general rules for the allowed or target revenue are set’ , while the tariff period stands for the time period ‘during which a particular level of reference price is applicable’ . The TAR NC also sets out the rules regarding the interrelation between the two concepts in terms of their duration. The tariff period is normally shorter than the regulatory period, and one regulatory period comprises several tariff periods. The tariff period may also coincide with the regulatory period, but one tariff period will never be associated with more than one regulatory period. In Austria and Belgium both the regulatory period and tariff period last four years, in Slovakia they last five years, while in Poland and Sweden they last only one year. Figures 9 and 10 show different regulatory periods and tariff periods in the MSs whose TSOs are ENTSOG Members   1) . No information appears for the MSs whose TSOs are ENTSOG’s Associated Partners. As part of the implementation of the TAR NC, the NRA may decide to change the tariff period and the regulatory period. The Maps below reflect the situation as of September 2017.
