Map 3:  2016 clustered countries – Daily BAL.2 indicator (in %) on days with TSO balancing actions

Map 3 illustrates the BAL.2 indicator for 2016 cluster. The 5 countries (CZ, ES, HR, IT, PT) have a similar range of balancing actions than some countries of 2015: DK, FR and SI. Since cluster 2016 did not had to apply the BAL NC in the first edition of this report, we cannot com- pare the number of days they have taken actions from GY 2015/2016 to GY 2016/2017. Italy took balancing actions on 270 days, Croatia 159 days, Spain 80 days, Czech Republic 48 days and Portugal only for 7 days.The yearly BAL.2. indicator in annex III shows a ranking correlated to the number of days when balanc- ing actions are taken. Map 4 shows countries which applied interim measures (cluster 2019 and Estonia who holds a derogation). Bulgarian and Estonian figures present a range of balancing actions very large. Romania, Latvia, Slovakia took less than 5 balancing actions during the year. In addition, there are no balancing actions on PL-L and PL-T balancing zones. So, the results of BAL2 for these balancing zones will not be presented and analysed.

However, Slovakia stated that the TSO takes care of the cross-border volume and the DSO takes balancing actions for Slovakia. On most Inter- connection points to their transmission network they have OBA (Operator Balancing Account) regimes, meaning that nominated quantity is equal to allocated quantity. Most of their imbal- ances arise from one IP, where there is no OBA regime, but these imbalances are very small, and they have a threshold of +/− 2,000MWh to start balancing action. There is mostly no need to balance these small imbalances as they are negative and positive in time. Most of the imbalances are from different nominated inputs/ outputs for individual shippers, but this happens only a few times per year. Lithuania has still, compared to last year, the smallest volume but balancing actions are taken almost daily. Poland High-methane gas balancing area has small volume and almost daily balancing actions.
