Overruns redistribution

As every year, GRTgaz puts back to shippers suppliers of end customers the penalties perceived for the overruns daily and hourly of their customers on the downstream network in 2016.

The concerned quantities represent 181 189 022,448 MWh at 0° for 2 359,14 K€ total amount. The unit price of redistribution is consequently 0,01302€/MWh.

The redistribution is calculated in proportion to the quantities delivered on the downstream network approval in 2016 for every concerned shipper. It appears on the invoice emitted in June, 2017.

Reminder of 2015 amounts : 156 644 436,452 MWh à 0° / 1 325 122,36 € / UP : 0,008459 €/MWh

INC PROCESS – Non-Binding Demand Indications at borders with Belgium and Germany

According to the procedure described in the COMMISSION REGULATION (EU) 2017/459 of 16 March 2017 (“CAM Network Code”) and COMMISSION REGULATION (EU) 2017/460 of 16 March 2017 (“TAR Network Code”), GRTgaz and adjacent operators conduct a common Demand Assessment for firm bundled capacity between their market areas.

Interested Parties are invited to address their Non-Binding Demand Indications for capacity to the TSOs. TSOs will assess the adequacy of the available capacities with market demand and the potential need to develop capacity between these two market areas.

Interested Parties can find here enclosed the documents to be submitted to GRTgaz SA for the Non-Binding Demand Indications:

Interested parties are requested take full notice of the above mentioned documents and submit their Non-Binding Demand Indication by post to the TSOs latest by June 1st, 2017. We remind you that any Non-Binding Demand Indication received without the Confidentiality Agreement duly completed, signed and dated will not be considered as a valid request.

Any request for information on this process can be addressed to the following e-mail: new-capacity(at)grtgaz.com.

Please find here after the timeline and overview of the process as published by ENTSOG

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:
