ENTSOG BAL NC Monitoring Report 2016

30 / 127

In other two countries (HR50) and RO51)) the im-
plementation of neutrality provisions is under
discussion.
According to BAL NC provisions, NRAs shall ap-
prove and publish the methodology for the cal-
culation of the neutrality charges for balancing
and TSOs shall publish the aggregate neutrality
charges for balancing at least monthly.
Compared to previous report where in three
countries (BG, HR and PT) no methodology for
the calculation of the neutrality charges was
published or was only planned to be published,
Bulgaria and Portugal reported the publication
of the methodology by 1 October 2016. Starting
from the same date, Portugal is also publishing
the monthly aggregated neutrality charges.
In Sweden, due to the fact that the amounts
gained or lost by undertaking balancing actions
are almost negligible, NRA decided not to imple-
ment the neutrality provisions, therefore no
methodology was published. Links to the publi-
cation of methodology and of monthly aggregat-
ed neutrality charges can be found in
In all 25 countries (included Estonia) except in
Croatia and Romania, the principle of neutrality
50) HR: The methodology for the calculation of the neutrality charges will be published and implemented by 1 April 2017.
51) RO: The document was in a public consultation in the beginning of 2016, and was subsequently withdrawn by NRA. Subsequently, based on the
proposals and comments from the market NRA requested Transgaz to update the project, therefore it was submitted again to public consultation
52) Germany: As opposed to the former system the portfolio within-day charges are only applicable when the MAM is buying and selling gas in the first
rank of the merit order list on the same gas day. In such a case, the applicable charge is determined by the difference of the weighted average
buy and sell prices divided by two.
is observed when balancing actions are under-
taking and, also, the costs and revenues arising
from balancing activities are passed to network
user.
The description of the rules for division of the
neutrality charge for balancing components and
the subsequent apportionment of the corre-
sponding sums amongst the network users
provided by the countries which decided to
implement them (art. 30.6) can be found in
Out of two countries (DE and PT) applying infor-
mation model “variant 2”, Germany reported
that the methodology for the calculation of the
neutrality charges for balancing provides rules
for a separate neutrality charge for balancing in
respect of non-daily metered off-takes and
offered a description. The description of the
rules can be found in
The methodology for the calculation of the
neutrality charges may provide rules for the
division of the neutrality charge for balancing
components and for the subsequent apportion-
ment of the corresponding sums amongst the
network users. Four countries (DE, ES, IE and
UK-NI) implemented these rules. Details can be
found in
3.7 WITHIN DAY OBLIGATIONS (CHAPTER VI OF BAL NC)
In order to incentivise network users to manage
their within day position in view of ensuring the
of the transmission system and minimising TSOs
need to undertake balancing actions, BAL NC
allows TSOs to implement Within day obligations
(WDOs) which are a set of rules approved by the
NRAs regarding network users’ inputs and off-
takes within the gas day.
As stated in the previous report, five countries
(AT, BE, DE, LU and NL) have already imple-
mented WDOs prior to 1 October 2016, while
Estonia finally decided not to implement any
WDOs. Bulgaria reported the intention of intro-
ducing WDOs, therefore the rules have been
elaborated and are subject to NRA’s approval.
(See also Map 9)
Three countries (BE, LU and NL) applied a Sys-
tem Wide WDO whereas two countries (AT, DE)
applied a Portfolio Based WDO. Compared to
previous Report, no changes intervene in those
countries.
Compared to previous report, in Germany the
regime of within-day obligations has changed by
1 October 201652).
In all five countries, WDOs are applied in order
to incentivise network users to manage their
within day position and TSOs provided a
description of the relationship between WDO
and end of the day balancing systems that can
