ACER calls for improvements to the proposed Belgian gas transmission tariffs
What is in the report?
ACER assesses the proposed methodology to calculate tariffs, including:
- The details on the input parameters to the methodology;
- The regulatory account and the accumulated congestion revenue; and
- The methodology applicable to the L-gas network to transport gas from the Netherlands to France.
What are ACER’s main findings?
The Agency observes that improvements on the proposed transmission tariffs can be achieved based on the provisions of the EU Network Code on Gas Transmission Tariffs and provides some recommendations to the Belgian national regulatory authority CREG.
ACER recommends to CREG to:
- Shorten the duration of the tariff period. This should facilitate the forecast of the contracted capacity, and should help minimise potential under- and over-recoveries as well as the reconciliation of the regulatory accounts.
- Compare (and publish) the forecasted contracted capacity vis-à-vis the realised contracted capacity. This improvement should allow improving the accuracy of the capacity forecast, improve the cost-reflectivity of tariffs and minimises the need to reconcile revenue.
- Ensure the reconciliation of the Transmission System Operator’s (TSO), regulatory accounts, which has accumulated significant over-recoveries, including significant congestion revenue.
- Provide information on the allowed revenue methodology of the TSO, in particular, on the regulatory asset base revaluation of the TSO.
- Provide additional transparency on the cost and the capacity forecast that is used for the calculation of tariffs.
