New: GB Gas dashboard

We've launched a GB Gas page covering National Transmission System flows for Great Britain — live supply and demand, linepack, and how the system is balancing through the gas day.

See how much is coming from UK Continental Shelf fields, Norwegian pipelines and LNG, and where it goes — to power stations, homes and heating, and exports. Track instantaneous rates, flows so far today, and a year of daily energy in GWh.

Open the new Gas dashboard to explore the data.
