In Britain, gas is used to heat homes and provide energy to businesses. It is also used to generate electricity.
National Grid, Britain’s gas system operator, publishes an outlook report on the availability of gas and electricity supplies ahead of each winter.
Their current outlook is that we will have more than enough gas to meet demand in all but the most extreme circumstances.
Our gas sources
We have one of the most reliable gas systems in the world.
Around half of our gas supplies come from our own North Sea gas fields. The remainder is imported from a variety of sources including Norway, the Continent, and across the world using liquefied natural gas.
This diversity means we are far less reliant on storage gas to meet our energy needs. In fact, less than 10% of the gas we use in winter comes from storage.
Roles and responsibilities
The responsibility to deliver secure gas supplies is shared between gas shippers (including energy suppliers) and National Grid.
Gas shippers buy gas on the wholesale market to meet the needs of their customers.
National Grid makes sure gas is transported safely on the networks, and that the gas system is kept in balance.
The government sets the long-term direction for energy policy.
What does Ofgem do?
Our role is to make sure the gas market works properly and that there are no barriers to stop gas companies from doing their job.
Each year we run a seminar for industry and stakeholders to discuss different perspectives on the supply and demand outlook, plus the risks and challenges for the winter ahead. Find out more in National Grid Outlook Seminars.
