A Comprehensive Guide to the 7 Great Britain’s Gas Points
All the gas in Great Britain comes in from one of 7 points, these points are scattered across the country.
At these points gas arrive in the UK, either by ship or via a pipeline:
- St Fergus
- Teesside
- Easington/Theddlethorpe
- Bacton
- Isle of Grain/Grain LNG
- Moffat
- Milford Haven
This article will provide you with more information on the 7 supply points, as well as develop your wider knowledge of the NTS (National Transmission System) and how it operates.
A GUIDE TO THE TABLES
CONNECTION TYPE – this explains whether the connection is across countries, and whether those countries are within the EU
OPERATOR – this is the entity responsible for transporting the produced gas across the network.
CAPACITY – this is the max technical physical capacity, measured in GWh/d (Gigawatt hour/days).
AVAILABLE FLOW DIRECTION – this is the direction in which gas can flow through the Transmission System Operator (TSO)
GCV – Gross Calorific Value, assumed GCV for conversion into kWh/Nm3
ST. FERGUS
| Connection Point Type | Operator | Capacity | Available flow direction | GCV (min) | GCV (max) |
| Cross-border interconnection with non-EU Countries | Gassco | 706,8 | TSO offers firm capacity in one direction | 11,000 | 11,000 |
The terminal is found in Aberdeenshire, Scotland. In total it receives around 25% of the UK’s gas.
TEESSIDE
| Connection Point Type | Operator | Capacity | Available flow direction | GCV (min) | GCV (max) |
| LNG Terminal’s Entry Points into Transmission System | Dockside Regasification | 444,6 | TSO offers firm capacity in one direction | 11,000 | 11,000 |
EASINGTON/THEDDLESTHORPE
| Connection Point Type | Operator | Capacity | Available flow direction | GCV (min) | GCV (max) |
| Cross-border interconnection with non-EU Countries | Gassco | 793,3 | TSO offers firm capacity in one direction | 11,000 | 11,000 |
The terminal is situated on the North Sea cost in the East Riding of Yorkshire. Up to 20% of the winter peak demand for gas is exported from Easington.
BACTON
| Connection Point Type | Operator | Capacity | Available flow direction | GCV (min) | GCV (max) |
| Cross-border interconnection within EU and with non-EU Countries | National Grid Gas – interconnector | 630,1 | Point physically bi-directional so TSO can offer firm capacity in both directions | 11,000 | 11,000 |
| Interconnector – National Grid Gas | 803,4 |
The terminal is a complex of six different terminals located on the North Sea coast of North Norfolk.
MOFFAT
| Connection Point Type | Operator | Capacity | Available flow direction | GCV (min) | GCV (max) |
| Cross-border interconnection within EU and with non-EU Countries | National Grid Gas – GNI (UK) | 431,7 | TSO offers firm capacity in one direction, and virtual backhaul capacity in the other | 11,000 | 11,000 |
| National Grid Gas – Premier Transmission |
The terminal can be found within Dumfries and Galloway.
