Map 4 shows countries which applied interim
measures (cluster 2019). Compared to most of
the countries with a deadline of 1 October 2015,
those countries reported much smaller market
entry volumes as an indication for the market
volume. An exception is Slovakia but it has high
transit volumes compared to the inland con-
sumption.
All of them except Poland reported applying in-
terim measures due to the absence of sufficient
liquidity of the wholesale gas market.
The Polish H-gas balancing zone has the biggest
yearly market entry volume of the countries ap-
plying interim measures (cluster 2019), but still
much smaller than most of countries in cluster
2015. TSO balancing actions occur on 340 days
in GY 2015/2016. On those days the daily total
TSO balancing volumes relative to the market
entry volumes fluctuate in 80% of the time
around 2.3% even though in exceptional cases
up to 6.3%. The TSO is balancing those volumes
via the usage of STSP on a trading platform (with
a yearly BAL.1 of 99.91%).
Lithuania is a very small gas market. TSO bal-
ancing actions occur almost daily in very small
volumes, therefore BAL.2 has a very low range
below 0.7%. On those days the total TSO bal-
ancing is conducted by the usage of balancing
services only (BAL.1 is 0%).
Slovakia has high transit volumes compared to
the internal market consumption. TSO balanc-
ing actions occur on only six gas days in GY
2015/2016 on those days the total range is min-
imal. The TSO performs its balancing volumes
partially via STSP on its balancing platform
(BAL.1 of 33.34%), but higher TSO balancing
volumes are conducted by using balancing
services.
Sweden is one of the smallest European gas
markets. TSO balancing action is performed on
only 19% of the days in GY 2015/2016, in 80%
of the time the range is around 5% of total TSO
balancing volumes compared to the market en-
try volumes on a daily basis. In exceptional cas-
es the indicator can increase up to 10%. The
TSO is performing balancing actions by trading
the weekly or regulated product when needed
on its balancing platform.
Ireland, Northern Ireland and Greece are very
small gas markets in Europe. The TSOs indicat-
ed to perform their balancing volumes by the us-
age of balancing services under interim meas-
ures as an alternative to a balancing platform. In
those countries the number of days when the
TSO is performing balancing actions is quite low.
Ireland and Northern Ireland balancing actions
occur on nearly the same number of days. But
the total range of the BAL.2 indicator (of 12.3%)
as well as the fluctuation of BAL.2 on 80% of the
time (with 5.6%) are higher than in Northern
Ireland with a total range of 11.8% and with a
fluctuation value of 4.3% on 80% of the time.
In Greece the TSO is performing balancing ac-
tions on only ca. 40% of days in GY 2015/2016.
In those cases one TSO balancing action occurs
per day. The range of balancing volumes relative
to the market entry volumes is high with 25%,
even though in 80% of the time the fluctuation
is limited to around 11%. The TSO indicated to
keep LNG reserves in LNG terminal tanks when
deemed to be necessary for the safe and effec-
tive operation of the transmission system. The
TSO is procuring those LNG quantities as a
balancing service on a daily basis in order to bal-
ance the system.
