ENTSOG BAL NC Monitoring Report 2016

3.4.3 Provision of Final Allocation Data

BAL NC does not define a time limit for TSOs to provide each network user with the final allocation for its inputs and off- takes and the final daily imbalance quantity. Such a time limit shall be defined at national level. All 25 countries including Estonia (AT, BE/LU, BG, CZ, DE, DK, EL, ES, FR, HR, HU, IE, IT, LT, NL, PL, PT, RO, SE, SI, SK, UK-GB and UK-NI) indicated that the timeframe for initial al- location no later than D+1 as well as for final data allocation by 1 October 2016. Croatia and Portugal have reported this time also the national applied timeframe for the final allocation data by 1 October 2016. Estonia provides the final allocation earlier as of 1 April 2016. BAL NC foresees the assessment of costs and benefits re- garding the (1) frequency, (2) reduction of related timelines and (3) improvement of accuracy of the information provided by 16 April 2016. TSOs should have done a cost benefit analysis (according to art. 38) within two years as from the entry into force of BAL NC (16 April 2016). Great Britain reported having performed its CBA including a public consultation. The finalisation of the process with an NRA decision on any proposed changes is yet to be complet- ed. Two countries (DK  35) and FR) reported having completed the CBA earlier. 21 countries including Estonia (AT, BE/LU, BG, CZ, DE, EL 36) , ES, HR, HU, IE, IT, LT, NL, PL, PT, RO, SE, SK, SI and UK-NI) reported that the complete CBA had not been performed by the deadline mentioned in BAL NC. Austria indicated that TSOs fulfil their obligations and publish data nearly in real time, while three other countries (BE/LU and SK) reported providing information on an hourly basis. In Bulgaria the new Balancing Rules apply only by 1 January 2017. In Estonia data exchange rules are to be implemented once the national legislation is updated. In Slovenia the TSO is closely following the development of the balancing market and trading platform. The balancing market situation is discussed with market participants on a regular basis. 3.4.4 Cost Benefit Analysis (CBA)

Different approaches are used regarding the final allocation provision. 22 countries including Estonia (AT, BG, CZ, DE, DK, EL, ES, FR, HR, HU, IE, IT, LT, PL, PT, RO, SE, SI, SK, UK-GB and UK-NI) use a comparably longer period (days/month) for the provision of final allocation data, however in these coun- tries the data already includes a reconciliation procedure. As in three countries (BE, LU and NL) the reconciliation is separated from the calculation of imbalance charges, the final allocation data can be provided for the whole gas day imme- diately within minutes after the gas day. Details per country on the timeframe in which final allocation data, used for the calculation of the daily imbalance charges, is submitted to network users can be found in Annex IV, table 4.6 and 4.7 . The Netherlands reported having performed CBA and the re- port will be sent to the NRA for their decision in January 2017. In three countries (HU, LT and PL 37) ) CBA is under prepara- tion or under development. In Ireland a full implementation of all information provision required by EU Network Codes is indicated to commence in Q1 2017. Northern Ireland reported that the CBA is in progress while Romania indicated the plan to prepare a CBA. Due to the modification of information provisions by 1 October 2016, the NRA in Germany decided to prolong the timeline for the CBA to October 2018. For the five countries applying transitory period (CZ, ES, HR, IT and PT) the implementation deadline expired in April 2016, Portugal therefore reported it as not being applicable. Croatia explained that BAL NC is not yet fully implemented. For Czech Republic the period with regards to the implementation dead- line by 1 July 2016 was too short. In Spain the NRA’s Circular implementing BAL NC establishes the CBA process before 30 September 2018. Italy indicated that the evaluation of the CBA results within two years should be counted from the implementation date of BAL NC provisions.

35) In Denmark the CBA was conducted before the implementation, and lead to increasing the information provision from 2 to 5 times a day. It was clear from this analysis, that increasing the information to more than 5 times a day would be extremely costly for the DSO’s, as this would require new measurement equipment for intra-daily metered sites. Therefore 5 times day was the final result of the CBA. 36) In Greece DESFA is in the process of upgrading our metering and SCADA system and installing a new IT platform for reasons that are not directly related to the implementation of BAL NC. As soon as this upgrade is completed the frequency of data provision may be increased. 37) For the Polish TGPS balancing zone: The allocation rule “allocation equal to confirmed nomination” shall apply. There is no need to provide any other information to network users. Therefore the CBA is not relevant.
