Our Data Portal provides access to a huge range of live and historical information on the National Transmission System (NTS). You can access forecast and live supply and demand, real-time flow rates, storage capacity, margins notices, linepack (the volume of gas within the NTS), maintenance plans, entry and exit capacity details and much more. Under our Gas System Operator (GSO) licence, we must provide open data, which we do via our portal.  

We want to ensure you can contact the right person if you have queries about specific operational gas issues. Our gas query directory is a comprehensive list of subject matter experts and their contact details. We have compiled the directory based on the most common queries we receive from our customers, to help you find the right person to resolve your issue quickly and easily.
