On 10% of the days when any shipper imbalances occur, the net volume of
shipper imbalances relative to the market entry volume of a balancing zone
(BAL.4) has a range between +5% and max.+15%. This means that the
market is LONG (+) at the end of the days within a range of 10%.
On 10% of the days when any shipper imbalances occur, the net volume of
shipper imbalances relative to the market entry volume of a balancing zone
(BAL.4) has a range between −5% and min. −15%. This means that the market
is SHORT (−) at the end of the days within a range of 10%.
On 80% of the days when any shipper
imbalances occur, the net volume of shipper
imbalances relative to the market entry volume
of a balancing zone (BAL.4) has a range
between −5% and +5%. This means that the
market is sometimes LONG (+) well as
sometimes SHORT (−)at the end of the days
within a range of 10%.

Example with explanation of the daily BAL.4 indicator in % on days with shipper imbalance volumes in GY 2015/2016
The relationship between BAL.4 and BAL.3 is
illustrated in Map 7 below. If BAL.4 is positive, it
means that the market is LONG (+), so there is
too much gas at the end of the day in the mar-
ket. In this case the TSO needs to provide the
gas by e.g. selling gas to the rest of the market in
order to keep the system balanced (positive
BAL.3). If BAL.4 is negative, it means that the
market is SHORT (-), so there is not enough gas
at the end of the days in the market. In this case
the TSO needs e. g. to buy gas from the rest of
the market in order to keep the system balanced
(negative BAL.3).
The countries are clustered in the following
maps regarding the applied implementation
deadlines into cluster 2015 (Map 8), cluster
2016 (Map 9) and cluster 2019 (Map 10).
Map 8 and map 9 illustrate the countries which
applied the implementation deadline by 1 Octo-
ber 2015 (cluster 2015). They are differentiated
into countries (AT, BE/LU, NL and DK) which
indicate the network users with a market signal
before undertaking TSO balancing actions on
the short term wholesale market (map 8). In oth-
er countries (UK-GB, DE, FR, HU and SI) the
TSO provides information regarding the overall
status of the system, but does not indicate to the
network users when undertaking concrete
balancing actions on the market.
In all 10 countries except Austria, net shipper
imbalances occur on a daily basis. On a few
days in GY 2015/2016, no shipper imbalances
seem to occur at all, the market was completely
balanced at the end of the day. Except in the
BELUX market areas and NCG where TSO
balancing actions have been undertaken on a
daily basis, they occurred on less days in the
other ones. In all balancing zones the net shipper
