Balancing target system - Principles

Wholesale short-term
market
Imbalances cashed-
out daily at
marginal price
1 - Network Users
Have primary responsability for
balancing the network by balancing
their portfolios
2 - TSOs
Carry out the residual balancing in order to
maintain the network within its operational
limits
Sufficient, well-timed and reliable information
In priority by using
short-term
standardised products
on the Exchange

Marginal buy / sell price
The marginal buy price (MBP) is the greater of :
The highest of any trades in which the TSO is involved
The daily average price (DAP) of all trades, plus a small adjustment
The marginal sell price (MSP) is the lesser of :
The lowest price of any trades in which the TSO is involved
The daily average price (DAP) of all trades, minus a small adjustment
Example for a gas day D :
Definition given by the Network Code

DAP - small adjustment

MBP = highest of TSO’s trades

GRTgaz market balancing actions
Current situation :
Since 1 August 2012, DA session has become optional.
Intervention volumes of WD and WE sessions based on the EOD imbalance indicator value, capped by a maximum volume.
Interventions made by a robot during a 15’ window : 3:45 pm to 4:00 pm for the WD session and 5:00 pm to 5:15 pm for the WE session
From 1 April 2013 :
Proportional interventions
No change of maximum volumes for WE sessions
Extension of the intervention windows to 30’
System parameters easily adjusted if needed
Further evolutions to the target
To be decided following feedback in 2013 and 2014
