In 2014, Bulgarian storage connection is being operated at full load, leaving no remaining flexibility. Hungary has remaining flexibility of 12%, in all other CEE coun- tries the value is above 20%. In 2018 and 2023 (FID case), Bulgaria, Croatia and Hungary have no remaining flexibility left in their storage connections. Poland’s remaining flexibility is expected to be 14.5% in 2018, but will increase to >20% in 2023 again. In the non-FID case, all countries would show remaining flexibility higher than 20% for their storage connections.
