Today, 10th May 2018, the SEM Committee publishes its decision approving the I-SEM Testing Tariffs for 2018 proposed by the TSOs. These tariffs will apply for the period of time from I-SEM goes live until the 31st of December 2018.
This paper replaces the SEM-18-023 decision due to an amendment of the wording utilised in that paper to account for the revised date of I-SEM Go-Live.
