Balancing: locational products are renewed

In the deliberation of September 15th, 2016, the CRE authorizes GRTgaz to pursue the experiment of locational products  for the residual balancing of the network.

The experiement was noticed by ACER which quotes GRTgaz in its report of last November 7th as an example to be followed for the implementation of its locational products which allowed a control of the costs of balancing and the implementation of a simple and pragmatic interface for the management of its linepack flexibility service instead of a contract of storage during winter 2015-2016.

More widely, France is greeted in the top 5 of the members countries for the quality of implementation of the balancing network code. The Agency observes that extensive information is provided to the market beyond the requirements in the Code and a regular and open dialogue with market players.

Optiflow: for more capacity and flexibility during maintenance periods

Optiflow will enable you to increase the availability of your capacities during maintenance periods on the core network. Thanks to Optiflow, the restrictions are mutualised on several entry points / exit points called “Superpoints”. If you subscribe capacities on several of the following points: Dunkerque LNG, Dunkerque, Alveringem, Taisnières H, Obergailbach, Oltingue, you get more flexibility to optimise your capacity on each point.

Whether you use only one point or several points, thanks to Optiflow you will enjoy a broader / wider UBI offer. Moreover, the maintenance program display will change for everybody.

Initially planned the April 1st 2017, Optiflow will be later displayed because of the current consolidation of Trans@ctions.

To help you to prepare the implementation of Optiflow, GRTgaz provides you with several tools:


More Dunkirk!

In order to face increasing demand from shippers, GRTgaz renews for the next winter the offer “ More Dunkerque”: an extra 20 GWh/d monthly firm capacity at Dunkerque IP will be commercialized from November 2016 to March 2017.
The total monthly firm capacity of Dunkerque IP increases from 570 to 590 GWh/d during this period. The level of interruptible capacity remains unchanged (36 GWh/d).

To this end, 20 GWh/d of firm capacity at Taisnières H will be commercialized as interruptible capacity instead of firm capacity during the same period. The monthly firm capacity at Taisnières H therefore decreases to 620 GWh/d instead of 640 GWh/d at present (plus 30 GWh/d overbooking capacity). And the level of interruptible capacity grows from 0 to 20 GWh/d, commercialized following CAM rules.

These additional capacities are commercialized via OSP on Trans@ctions each Month M-1, the first one from 1st to 11th of October 2016. Unsold capacities will be proposed as daily capacities.
