National Grid ? Generators ? Distributors ? Suppliers
The National Grid
• The national transmission network, owned by National Grid, maintains the flow of generated electricity through to the regional distribution networks.
• The National Grid own and maintain the high- voltage electricity transmission network in England and Wales (Scotland has its own networks).
• This involves carrying electricity from the generators to substations where the voltage is lowered ready for distribution.
• They are responsible for balancing the system and managing generation output to make sure that it matches demand throughout the day.
• Generators, distribution network operators and suppliers pay the National Grid for the right to connect to their assets and to transport electricity on their behalf.
COAL | GAS | NUCLEAR | RENEWABLE
• Produce electricity from coal, gas, oil and nuclear power plants and from hydroelectric plants and wind farms. Electricity can’t be stored efficiently so is generated as needed. We don’t own or operate any of these electricity generation plants.
• In the UK, electricity is generated in a number of different ways.
• It is important to have different fuel sourceS and technologies to generate electricity so that there is a constant supply and the industry is not overly reliant on one type of power generation.
OFFSHORE HAS FIELDS | PIPELINES FROM EUROPE | LIQUIFIED NATURAL GAS
Britain now gets its gas from a wide range of sources to make sure the country always has the supply it needs. This includes:
• North and Irish Sea production (currently approx 40%).
• Pipelines from continental Europe and Norway.
• Liquefied Natural Gas (LNG) shipped in from around the world.
