Small adjustment (Art. 22.6)
As part of the approved calculation methodolo-
gy, the small adjustment contributes to deter-
mine the marginal sell and buy price. Its role is
to incentivise network users to balance their
inputs and off-takes.
Out of 18 countries where the daily imbalance
charge methodology applies, 14 countries (BE,
CZ, DE, DK, ES, FR, HU, IT, LT, LU, PL (H-gas),
PT, SI and UK-GB) reported the implementation
of a small adjustment in accordance with article
22.6 of BAL NC by 1 October 2016. In two coun-
tries (EE and HR) the daily imbalance charge
calculation methodology is still under develop-
ment. In Hungary, the small adjustment is zero.
As already stated in the previous report Austria
and Netherlands repeated the small adjustment
as not applicable.44) (Further details can be
found in .
The other seven countries (EL, IE, PL (L-gas and
TGPS), RO, SE, SK and UK-NI) reported the im-
plementation of an interim imbalance charge
while Bulgaria plans to implement the interim
imbalance charge during 2017. (More details
can be found in of this report deal-
ing with interim measures).
44) See also footnote 51 and 52 for AT and NL in applicable price section.
45) The Methodology shall be applied during 2017.
Daily imbalance charge calculation (Art. 23)
The reduction of network users’ daily imbalance
quantities to zero each day, instead of rolling
over to subsequent days, is an important ele-
ment of a daily imbalance charge methodology.
In 20 countries (BE, BG45), DE, DK, EL, ES, FR,
HU, IE, IT, LT, LU, PL, PT, RO, SE, SK, SI,
UK-GB and UK-NI) network users’ daily imbal-
ance quantities are reduced to zero each day on
payment of the daily imbalance charges.
In Austria, if the imbalances are below tradable
volumes (<24MWh/d) they will be considered
as carry-forward for the next gas day.
Due to the linepack flexibility service offered in
Czech Republic, daily imbalance charge is paid
only for a part of the individual imbalance that
exceeds a specific range and the imbalance
quantity within the range rolls over to subse-
quent days. In the Netherlands the daily imbal-
ance quantities are absorbed by the offered
linepack flexibility service according to art. 21.2
of BAL NC.
Estonia applies a monthly accounting period,
while in Croatia a daily imbalance charge calcu-
lation methodology is under development.
