1. Introduction
Status implementation
Certification
• Over 80% of current market parties are certified by EDSN and cover
almost 100% percent of market volume
• Certification is mandatory for PVs
Means for Bid price ladder
• At his moment 8 market parties plan to participate in the bid price
ladder
Follow up
• Few shippers show no progress at all – addressed by GTS
6
1. Introduction
Joint tests
The following phases start with a Getting started document:
- Phase I October and November 2010 – SBS and POS
- Phase II December 2010 – Programmes and allocation data
- Phase III January and February 2011 – Market test with
programmes, BPL and balancing agreement
- Phase IV March 2011 – Metering data
- Phase live
7
1. Introduction
New market parties
• All market parties have a account manager (AM)
• Read the ToDo on the GTS market transition website and
discuss with account managers how obtain necessary
knowledge
• Apply for EDSN certification
• Discuss with AM participation joint tests

1. Introduction
Next steps
• 10 November 2010 workshop Dispatchers
• November 2010 publishing getting started phase II joint tests
• December 2010 Questionnaires
• January 2011 Focus on procedure bid price ladder means

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.

2. Essentials market design
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
Call bid price ladder

2. Essentials market design
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

2. Essentials market design
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
Unchanged
• 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

Refresher: Purpose of 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

– 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

 Damping is obligatory if the Exit Programme is for a
portfolio that includes Protected Users.
 Damping calculated with damping formula and alpha and
beta parameters
 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

 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
44
Programme validation: internal consistency (2)
 GTS sends APERAK message to PV’s for each
programme:
– APERAK for Entry and Trade programme contains
information on both syntactic and internal consistency
check
– Before 09:00 APERAK 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 APERAK with information
on internal consistency check
– After 09:00 APERAK for Exit programme contains
information on both syntactic and internal consistency
check
45
Programme validation: External consistency (1)
 GTS checks external consistency (VPPV
transfers) of programmes.
– First check by GTS at 14:00
– Last check by GTS at 22:00
– If checks fail GTS applies default rules
 Default rules do not lead to a chain of external
consistency check failures (limited to directly
involved programmes)
46
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
49
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
50
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

– Total physical exit (GSTPEXIT) = Σ physical exits
– Damping (GSTPD) = damping
 If an exit programme is internally or externally

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?
64
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.

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
