TAR NC
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.
Publication before tariff period – Tariff no. 18.
According to Article 30 of the Regulation transmission system operators are required to publish information on parameters used in the applied reference price methodology and information on the operator's planned revenues and costs and their allocation no later than thirty days before the respective tariff period.
- Forecasted contracted capacities and gas flows by balancing area, Article 30(3);
- Simplified tariff model for high-methane gas;
- Simplified tariff model for low-methane gas.
