1. Introduction and essentials market model
The hourly imbalance per portfolio is based on near real-time
entry and exit allocations, TTF and BPL1 transfers and damping

(sold -13 and bought 3)
• Imbalance calculation is (more or less) unchanged2 compared to
the current system, except when damping is applied (cf. using t+2
in the current system)
• Damping can be applied based on the exit volumes (exit
programme)

1. Introduction and essentials market model
The Portfolio Imbalance Signal (POS) is the cumulative hourly
imbalance per portfolio.

The System Balance Signal (SBS) is the sum of all POSses and
therefore reflects the physical imbalance of the grid.

1. Introduction and essentials market model
When the imbalance is exceeding a pre-set system limit the
imbalance will be solved by calling the bid price ladder
• No bandwidth or tolerance per portfolio but for the system
as a whole
• The bid price ladder contains bids of PV’s for solving the
imbalance of the system
• Calling the bid price ladder implies that GTS buys or sells
gas (on the bid price ladder) in order to restore the system
balance

1. Introduction and essentials market model
PVs send a programme (day-ahead) to GTS with a forecast of
the entry, exit and TTF allocations per portfolio
• Programmes enable GTS to determine the expected system load
by which GTS can set the limits of the system
• Programmes enable GTS and PVs to apply the damping
• Programmes do not have impact on the hourly imbalance (and
therefore on POS and SBS) except when damping is applied

1. Introduction and essentials market model
The difference between near real-time allocations and offline
allocations will be settled.
• The offline allocations are near real-time allocations with
corrections applies if necessary
• The corrections will be settled by GTS and have no impact on the
POS of PVs
Nominations and capacity
• Nominations are still required at entry and exit points wherever
GTS needs nominations for technical transport reasons or for the
purpose of calculation of the assignment of interruptible capacity
or points where they are needed to determine allocations
• Entry and exit capacity will still be booked both firm and
interruptible

General Information
16
General Information: Time
 Imbalances are determined per whole clock hour
 The whole clock hour is also used in both old (nominations
and confirmations) and new messages (programmes, bid
price ladder), e.g. the gas flow from 06:00:00 to
07:00:00 will be 1.000.000 kWh
 Leadtimes are relative to the start of the whole clock hour,
e.g. a leadtime of thirty minutes for the hour from
06:00:00 to 07:00:00 means the information must be
received by 05:30:00 at the latest
 There is no longer a daily reset and cash-out of imbalance
positions. POS cumulation runs continuously.
17
General Information: Lead time reduction

Applies to most networkpoints, see website for list.

Network point capacity < 50.000 m3/h = no restrictions in flow
change up to booked firm capacity.

Network point capacity >= 50.000 m3/h = difference between
H-2 nomination and H-½ nomination:
– Max (25% of the firm capacity booked, 50.000 m3/h)

Bidirectional network points >= 50.000 m3/h = difference
between H-2 nomination and H-½ nomination:
– Max (25% of the largest firm capacity booked, 50.000 m3/h)

For the purpose of determining the firm capacity booked by a
party, all relevant portfolios of the party and (any) affiliated
companies will be taken into account.

Programmes
 Programmes are the PV’s prediction of the planned
entry, exit and TTF flows per portfolio for the next
gas day
 GTS aggregates programmes to a prediction for the
system load
 Programmes enable GTS and PVs to apply the
damping
 Programmes do not have impact on the hourly
imbalance (and therefore on POS and SBS) except
when damping is applied

Programme types
 PV’s send either 1 or 2 programmes per
portfolio:
– An exit programme is required for a portfolio with
physical exit
– An entry programme is required for a portfolio
with physical entry
– A trade programme is required for a portfolio
without physical entry or physical exit
 EDIG@S Message Type PRODOC
 Always for one complete gas day
 If a PV sends an entry programme it is recommendable to
put the TTF deals in the entry programme (instead of in
the exit programme).

Programme content: Exit programme

Damping is obligatory if the Exit Programme is for a portfolio
that includes Protected Users. Optional for other Exit
Programmes

If damping is optional the choice has to be made before 01-Jan
and is valid for one year.

The damping is calculated with damping formula and alpha and
beta parameters, see next slide.

Internally consistent when Σ Entry + Σ Exit + Damping = 0
using GTS sign convention

Damping is implicit in PRODOC message as the difference
between sum of exits and net entry on VPPV; the values are not
included in the message.

Programme validation: internal consistency (1)
 GTS checks syntactic correctness of programme
message upon receipt
 GTS checks internal consistency of programme:
– For Entry and Trade programmes upon receipt
– For Exit programmes:
– at 09:00 D-1 (after publication alpha and beta) for
programmes for D received before 09:00
– Upon receipt of programmes for D received after 09:00
 If check fails GTS applies default rules to
programmes at time of confirmation: any damping in
an exit programme is lost
42
Programme validation: internal consistency (2)
 GTS sends ACKNOW message to PV’s for each
programme:
– ACKNOW for Entry and Trade programme contains
information on both syntactic and internal consistency
check
– Before 09:00 ACKNOW for Exit programme only
contains information on syntactic check
– If a PV sends in an Exit programme before 09:00 then
at 09:00 PV receives second ACKNOW with information
on internal consistency check
– After 09:00 ACKNOW for Exit programme contains
information on both syntactic and internal consistency
check

44
Programme validation: External consistency (1)
 GTS checks external consistency (VPPV transfers) of
programmes and applies default rules in case of
mismatches.
 Default rules do not lead to a chain of external consistency
check failures (limited to directly involved programmes).
 Matched and confirmed VPPV transfers can only be
changed if both parties submit new, matching values for
the VPPV transfer.
 If after a matching and confirmation cycle all programmes
are correct, the programme process ends and no new
programmes can be submitted.
45
Programme validation: External consistency (2)
For each transfer between programmes on the VPPV
GTS matches the following:
 The submitted counterportfolio
 The submitted volume
 The specified time period
 The direction of the transfer
Transfers which mismatch are set to zero.
Transfers submitted by a clearing house (e.g. APX) are
assumed to be correct and override transfers
submitted by PV’s

Programme confirmation (1)
 After each check GTS communicates the result
to the PV’s:
– EDIG@S Message Type PROCON
– Message Statuses allow PV’s to identify and correct
errors
– New confirmations are sent if statuses change
 The PROCON message includes additional
dummy counterportfolios that confirm total
flows and damping
48
Programme confirmation (2)
 Dummy counterportfolios for the exit programme:
– GSTPEXIT: total hourly physical exit
– GSTPVPPVEN: net hourly virtual entry
– GSTPD: damping
 Dummy counterportfolios for the entry programme:
– GSTPVPPVEX: net hourly virtual exit
– GSTPD: damping
 Dummy counterportfolios for the trade programme:
– GSTPVPPVEN: total hourly virtual entry
– GSTPVPPVEX: total hourly virtual exit
– GSTPD: damping
49
Programme Confirmation (3): Trade
 If a trade programme is internally and externally consistent:
– Virtual Entry (GSTPVPPVEN) = Σ VPPV transfers that are entry
– Virtual Exit (GSTPVPPVEX) = Σ VPPV transfers that are exit
– Damping (GSTPD) = 0
 If a trade programme is internally or externally inconsistent :
– Virtual Entry (GSTPVPPVEN) = Σ VPPV transfers that are entry
– Virtual Exit (GSTPVPPVEX) = Σ VPPV transfers that are exit
– Virtual Exit (GSTPVPPVEX) =
MIN(ABS(GSTPVPPVEN),ABS(GSTPVPPVEX))
– Virtual Entry (GSTPVPPVEN) = - GSTPVPPVEX
– Damping (GSTPD) = 0

Process
 When will the bid price ladder be called?
 How will the volume to be called be determined?
 How will the bidders be informed what is called from
them?
 How will the called volume be divided over the
causers?
 How will the assistance gas be divided?
72
Process: When will the bid price ladder be called?
 If the predicted SBS is in the Light Green Zone then
the bid price ladder is only called upon if the
absolute value of the predicted SBS is larger than
the absolute value of the predicted SBS for the
previous hour.
 If the predicted SBS is in the Orange Zone then the
bid price ladder is always called.

Short and Long: SBS Short and not in Dark Green Zone
 Short means the gas transport system as a whole
contains less gas than planned
 GTS will buy gas and therefore select bids from the
BPL with the direction “Entry”: an offer to sell gas to
GTS and therefore bring it into the system
 Bidder Clearing Confirmation has direction “Exit”
(exit on BAP; PV sells gas to GTS)
 Causer Clearing Confirmation has direction “Entry”
(entry on BVP; PV buys gas from GTS)
 Assistance gas: Helper Clearing Confirmation has
direction “Exit” (exit on AHP; PV sells gas to GTS)
 Assistance gas: Causer Clearing Confirmation has
direction “Entry” (entry on AVP; PV buys gas from
GTS)

Short and Long: SBS Long and not in Dark Green Zone
 Long means the gas transport system as a whole
contains more gas than planned
 GTS will sell gas and therefore select bids from the
BPL with the direction “Exit”: an offer to buy gas
from GTS and therefore take it out of the system
 Bidder Clearing Confirmation has direction “Entry”

How will the volume to be called be determined? (2)
 Call Correction Factor (CCF): A percentage GTS can adjust
in order to prevent bid ladder calls leading to system
instability.
– There are two CCF’s: one for the Light Green Zone and one
for the Orange Zone
– Value can be changed daily
– Published at 09:00 along with other parameters
– Expected start value CCF is 100%
 Incentive component (IC): an extra price on top of the
marginal price.
– GTS will adjust the incentive component based on how often
and for how much volume the SBS enters the Orange and
Red Zones
– Incentive to market parties to improve their balancing
– Expected start value is zero EUR/MWh

Bidder Clearing Confirmation:
• Adjusts POS in hour T+1 of T+2
of T+3
• Contains transactions between
GTS and PV
• Shows volume en price
• Transactions are on virtual point:
BAP
• Direction opposite to called bid
Bid price ladder Activation:
• PV receives 1 activation in
hour T
• Activation tells PV:
– locations called means
– volume per mean
– price
• PV must take action
(nominate) to make gas flow

Differences Gasport v.s. B2B information services
–B2B is a download service which can used for real-time integration of GTS data within
customer specific processes (applications). Exchange of XML messages between IT-systems
–B2B downloads operates with fixed units for example everything is in CET en KWh.
–B2B Information services POS & SBS services are part of the PV acknowledgment
requirements
–Gasport is a end-user solution providing predefined information by means of user friendly
web pages.
–Gasport works with customer adjustable units for example CET or LET, and KWh, MJ,
m3(35,17)
–Only in Gasport market parties can view the Bid Price ladder
