First Gas aims to introduce the GTAC project and its supporting IT system, TACOS (Transmission Access Commercial Operating System), on 1 April 2020. Communications and updates on that work can be found on the First Gas website here.

Listed in the left-hand navigation pane are the various stages of the GTAC development and assessment. The assessments relate to Gas Industry Co’s consideration of whether the GTAC would provide access that is materially better than the existing terms and conditions for access to and use of gas transmission pipelines.
