TAR NC (Network Code on harmonised transmission tariff structures for gas) is a code established by the European Union by means of Commission Regulation (EU) 2017/460.

The purpose of the TAR NC is to harmonise the transmission tariff structures of Member States’ operators and to provide a tool for comparing transmission tariffs applied across the EU, while maintaining flexibility in the selection of the components of the reference price methodology, as appropriate for the maturity of the specific market and the complexity of the transmission network.

In accordance with Article 29 of the NC Code, prior to the annual auction of yearly capacity products, GAZ-SYSTEM publishes information on reserve prices, multipliers and seasonal factors for short-term products, and on discounts for interruptible products.
