effing poor journalism.....
there is in place a very powerful model for working the pipeline system during heavy domestic demand. Simply put, there are major users across the UK such as steel works, breweries, glassworks, car plants, who use an enormous amount of gas on a daily basis - even major hospitals. These customers have what are called interruptible contracts - whereby they have to cut off the gas to release more product into the network during cold periods and switch to an alternative fuel, usually gasoil.....they get 5 hours notice and if they don't switch, there are enormous financial penalties. In return, they get cheaper deals for their load and offering the risk of this..... So there is plenty in the system....it's journo hype.
