ENTSOG BAL NC Monitoring Report 2016

In other two countries (HR  50) and RO  51) ) the im- plementation of neutrality provisions is under discussion. According to BAL NC provisions, NRAs shall ap- prove and publish the methodology for the cal- culation of the neutrality charges for balancing and TSOs shall publish the aggregate neutrality charges for balancing at least monthly. Compared to previous report where in three countries (BG, HR and PT) no methodology for the calculation of the neutrality charges was published or was only planned to be published, Bulgaria and Portugal reported the publication of the methodology by 1 October 2016. Starting from the same date, Portugal is also publishing the monthly aggregated neutrality charges. In Sweden, due to the fact that the amounts gained or lost by undertaking balancing actions are almost negligible, NRA decided not to imple- ment the neutrality provisions, therefore no methodology was published. Links to the publi- cation of methodology and of monthly aggregat- ed neutrality charges can be found in Annex I, table 1.3 . In order to incentivise network users to manage their within day position in view of ensuring the of the transmission system and minimising TSOs need to undertake balancing actions, BAL NC allows TSOs to implement Within day obligations (WDOs) which are a set of rules approved by the NRAs regarding network users’ inputs and off- takes within the gas day. As stated in the previous report, five countries (AT, BE, DE, LU and NL) have already imple- mented WDOs prior to 1 October 2016, while Estonia finally decided not to implement any WDOs. Bulgaria reported the intention of intro- ducing WDOs, therefore the rules have been elaborated and are subject to NRA’s approval. (See also Map 9) In all 25 countries (included Estonia) except in Croatia and Romania, the principle of neutrality

is observed when balancing actions are under- taking and, also, the costs and revenues arising from balancing activities are passed to network user. The description of the rules for division of the neutrality charge for balancing components and the subsequent apportionment of the corre- sponding sums amongst the network users provided by the countries which decided to implement them (art. 30.6) can be found in Annex VI, table 6.3 . Out of two countries (DE and PT) applying infor- mation model “variant 2”, Germany reported that the methodology for the calculation of the neutrality charges for balancing provides rules for a separate neutrality charge for balancing in respect of non-daily metered off-takes and offered a description. The description of the rules can be found in Annex VI, table 6.3 . The methodology for the calculation of the neutrality charges may provide rules for the division of the neutrality charge for balancing components and for the subsequent apportion- ment of the corresponding sums amongst the network users. Four countries (DE, ES, IE and UK-NI) implemented these rules. Details can be found in Annex VI, table 6.3 . Three countries (BE, LU and NL) applied a Sys- tem Wide WDO whereas two countries (AT, DE) applied a Portfolio Based WDO. Compared to previous Report, no changes intervene in those countries. Compared to previous report, in Germany the regime of within-day obligations has changed by 1 October 2016  52) . In all five countries, WDOs are applied in order to incentivise network users to manage their within day position and TSOs provided a description of the relationship between WDO and end of the day balancing systems that can be found in Annex VII, table 7.1 .

3.7 WITHIN DAY OBLIGATIONS (CHAPTER VI OF BAL NC)

50) HR: The methodology for the calculation of the neutrality charges will be published and implemented by 1 April 2017. 51) RO: The document was in a public consultation in the beginning of 2016, and was subsequently withdrawn by NRA. Subsequently, based on the proposals and comments from the market NRA requested Transgaz to update the project, therefore it was submitted again to public consultation 52) Germany: As opposed to the former system the portfolio within-day charges are only applicable when the MAM is buying and selling gas in the first rank of the merit order list on the same gas day. In such a case, the applicable charge is determined by the difference of the weighted average buy and sell prices divided by two.
