Implementation
Article 9
1. Section 7 of the Annex sets out the steps to be followed for the implementation of a fully interoperable energy subsystem. Without prejudice to Article 20 of Directive 2008/57/EC, Member States shall prepare a national implementation plan, describing their actions to comply with this TSI, in accordance with Section 7 of the Annex. Member States shall send their national implementation plan to the other Member States and the Commission by 31 December 2015. Member States that have already sent their implementation plan do not have to send it again. 2. Pursuant to Article 20 of Directive 2008/57/EC, when a new authorisation is required and if the TSI is not fully applied, Member States shall notify the following information to the Commission: — the reason why the TSI is not fully applied, — the technical characteristics applicable instead of the TSI, — the bodies responsible for applying the verification procedure referred to in Article 18 of the Directive 2008/57/EC. 3. Member States shall send to the Commission a report on the implementation of Article 20 of Directive 2008/57/EC concerning the energy subsystem three years after the entry into force of this Regulation. This report shall be discussed in the Committee set up by Article 29 of Directive 2008/57/EC and, where appropriate, the TSI in the Annex shall be adapted. 4. In addition to the implementation of the on-ground energy data collecting system (DCS) defined in point 7.2.4 of the Annex and without prejudice to provisions of point 4.2.8.2.8 of the Annex of Commission Regulation (EU) No 1302/2014 ( 7 ) , Member States shall ensure that an on-ground settlement system capable to receive data from a DCS and accept it for billing is implemented, two years after the closing of the open points mentioned in point 4.2.17 of the Annex. The on-ground settlement system shall be able to exchange compiled energy billing data (CEBD) with other settlement systems, validate the CEBD and allocate the consumption data to the correct parties. This shall be done by taking into account the relevant legislation concerning the energy market.
