Stek has assisted the shippers DONG Energy, RWE Trade & Supply and Eneco Energy Trade in a dispute before the Authority for Consumers and Markets (ACM) with respect to the qualification of the so-called WQA (Wobbe Quality Adaptation) service. This WQA-service is provided by Gasunie Transport Services (GTS) in the vicinity of the LNG-terminal of Gate and is charged back-to-back by Gate to the shippers. The shippers have submitted a complaint with ACM on the tariffs for the WQA-service. By decision of 27 November 2015 ACM sided with the shippers in ruling that the WQA-service must be qualified as quality conversion and is included in the transport service of GTS. As a result the shippers will get back tens of millions of euro’s in tariffs paid.
