Electricity Transmission Network Allowed Revenues and Demand Transmission Use of System D-TUoS tariffs (2021 – 2025)
The CRU has published an Information Paper on the Electricity Transmission Network Allowed Revenues for 2023 and the associated Demand Transmission Use of System (D-TUoS) tariffs for the 2022/2023 tariff year.
This Information Paper sets out the update to the Allowed Revenues that the transmission network companies, EirGrid (TSO) and ESB Networks (TAO), may recover during the calendar year 2022. These revenues are required for the efficient operation and maintenance of the electricity transmission system to ensure that the network delivers a reliable supply for the consumers.
Furthermore, the paper sets out the CRU’s decision on the associated Demand Transmission Use of System (TUoS) tariffs that will apply to demand customers from 01 October 2022 to 30 September 2023.
The transmission Average Unit Price (AUP) for the 2022/2023 period is estimated to be €2.92c/kWh, which is an increase of circa 44.8% relative to the current AUP. The increase is largely driven by the CRU’s provision of costs associated with securing emergency generation for 2022/2023. The combined transmission and distribution AUP for the 2022/2023 period is estimated to be €6.00c/kWh, which is an increase of circa 22% relative to the current AUP.
The D-TUoS tariffs are charged to suppliers, who may choose how, or whether, to pass them on to their customers. A customer’s annual bills depend on other factors such as wholesale market costs (which are in turn driven by factors such as international commodity prices), capacity market costs and other system costs.
