With the start of storage facilities regulation, in 2018 Teréga became a 100% regulated company. This regulation improves Teréga's risk profile, but means a significant drop in revenue tied to storage activity: - 13% from 2017 for €154m in turnover. Nevertheless, the successful sales campaigns surrounding storage capacities reflect the strong performance of this activity.
Transport activity recorded over 9% growth for €322m in turnover. This increase is mainly thanks to the award of a €15m European grant supplement for the Béarn pipeline project.
