Balancing target system - Principles

5

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

market

Market based system

What sets the European Balancing Network Code



The design process of the French system

6

A progressive process in close consultation with the

French market

Pending deliberation that will decide on the roadmad to comply with the European agenda

Prices P1 and P2 used to cash-out

imbalances outside mid-ranges and

tolerances



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

MSP = DAP – small adjustment


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
