A new step for French gas market players

As of 1 October 2015, GRTgaz is implementing the European Network Code on Gas Balancing of Transmission Networks.

GRTgaz is one of the first TSOs in Europe to implement the code, which aims to make sure that shippers take responsibility for balancing their portfolios and the gas transmission network as a whole1.

Under the new rules2, shippers must now supply the TSO with quantities of gas precisely equal to the quantities delivered in each balancing zone. To manage their portfolios, shippers are encouraged to use market instruments on the Powernext exchange or to trade forwards. This new system should promote dynamism and liquidity on the PEG Nord and Trading Region South (TRS) marketplaces in France.

GRTgaz is now capable of intervening in the market 4 times a day, 7 days a week to ensure residual balancing and thus preserve network stability. The price applied to shipper imbalances is representative of the cost borne by the TSO on the days when it intervenes.

GRTgaz worked in conjunction with market players to introduce these new rules, efforts which resulted in a proposal for a new linepack-based flexibility service. This service, known as Alizés, is aimed at shippers who supply sites exposed to fluctuations in consumption, chiefly due to climate factors. Shippers who sign up for the service will be exempted from full settlement of their imbalances each day that GRTgaz does not have to intervene in the balancing zone concerned.

1In accordance with Regulation (EU) No 312/2014 of 26 March 2014 establishing a Network Code on Gas Balancing of Transmission Networks.
