ENTSOG BAL NC Monitoring Report 2016

Poland – High-methane gas balancing area The yearly BAL.1 indicator of 99.9% indicates that the balancing in the Polish High-methane gas balancing area (H-gas) has been conducted mostly via STSPs on the trading platform. The daily BAL.1 indicator illustrates that until the end of 2015 balancing actions have only been conducted via STSPs, and on some days no actions have been done at all by the TSO. On 1 January 2016 only balancing services have been used, while in the period afterward, daily TSO balancing actions via STSP with a very small value of balancing services can be recognised. The fluctuation of the daily BAL.1 is therefore very low.
