National Grid owns a liquefied natural gas (LNG) facility at Avonmouth that provides a combination of commercial and regulated services.
The facility supplies operating margins services and Constrained LNG to National Grid Gas in support of the transmission system. In addition, it supplies LNG by tanker to SGN to serve the needs of the Scottish Independent Undertakings.
All of these regulated services are provided at prices set out in Special Licence Condition 11E of the gas transporter’s licence (formerly known as the C3 price). These regulated prices were reviewed in 2013 and will last until April 2018.
