In the same French regulatory framework, differences of total
TSO trading volumes as well as the days on which the TSOs
have been trading those volumes can be seen for GRTgaz and
TRS in Map 2 below. Compared to GRTgaz North, the peak as
well as the fluctuation of daily TSO balancing volumes in the
French TRS trading region is in general much higher. Both
trade on less than 44% of the days in GY 2015/2016, but the
TSO in GRTgaz North is performing balancing actions on even
less days (32%).
Denmark has a high peak as well as in its range. It might be
an indication for the low within-day market liquidity which has
been reported as a challenge after the BAL NC implementa-
tion. Anyway the Danish TSO is acting for balancing purposes
on less than 40% of the days on the market in GY 2015/2016.
Hungary is performing balancing actions on even less than
35% of the days and a lower peak of 11%. Slovenia is a very
small gas market. The TSO there is active on around 80% of
the days due to balancing purposes, but on those days the
peak can be very high with almost 25% at some days. After
May 2016 the TSO was trading only STSP when needed while
additionally the days when balancing actions occurred
reduced.
Map 3 illustrates the BAL.2 indicator for Czech Republic with
an implementation deadline by 1 July 2016 (cluster 2016).
Therefore the 3-month period from 1 July until end of GY
2015/2016 has been only taken into account. The TSO per-
formed balancing actions only on one day in August 2016
therefore BAL.2 is not fluctuating, but is constant with a value
of 0.79%. The reason is the line pack flexibility service which
is in place. Further details regarding the service mechanism
can be found in Chapter 4.3.
