Each year, the gas network tariffs are reviewed to ensure that Gas Networks Ireland (GNI) only recovers the necessary costs for efficient operation of the network. In June 2020, the Commission for Regulation of Utilities (CRU) reviewed and published a decision on transmission and distribution tariffs for the gas year 2020/21. The gas year 2020/21 runs from 01 October 2020 to 30 September 2021. The Commission’s decision was published on 05 June and will see gas tariffs increase on 01 October 2020.
On 28 August 2020, the CRU published an Information Paper detailing gas transmission tariff information for 2020/21. The requirements for the publication of this information are set out under Article 30 of the EU network code on harmonised transmission tariff structures for gas (TAR NC). With this Information Paper the CRU has aimed to create a single resource for all gas network transmission tariff related information, ranging from; how it sets tariffs on an annual basis, the variables that cause changes in the tariffs from one year to the next, and the tariffs for the upcoming gas year.
This document group also contains a Call for Evidence Paper titled ‘Gas Transmission Tariff Methodology – Tariff Network Code Article 28 Call for Evidence’. The call for evidence sought input into a detailed review of multipliers, seasonal factors and discounts (e.g. discount for Virtual Reverse Flow). These items impact how the costs of the gas network are charged to shippers and may in turn impact on customers’ bills. The response period closed on 14 July 2020 and the CRU will consider these responses as part of the detailed review in advance of gas year 2021/22.
