Croatia ratio could be misleading since they have moved from a balancing platform to a trading platform on the 1 April 2017. From this moment on, the TSO is only using WD title product (at 100%), see figure 1. The same misinterpretation could be made with Lithuania which has reduced the use of balancing services in 2017 and has used only WD title product from 2 July 2017 on , see figure 2. Portugal relies only on balancing services. However, only 7 balancing actions have been taken during the whole year and the implemen- tation of the MIBGAS trading platform (is expect-

ed in 2018). MIBGAS is the trading platform in force in Spain since December 2015 and it will be expanded to Portugal in 2018. Regarding the 9 other countries having interim measures in place or holding a derogation, Latvia, Slovakia and Romania have taken less than 5 balancing actions during the year via balancing services or balancing platform. For Bulgaria, Greece, Ireland, Sweden, Northern Ireland and Estonia, they are using only balanc- ing services.
