This page has been set up to provide high level information, to assist potential providers of services to National Grid.  We encourage potential service providers to contact us for more detailed information on our service requirements and how they might be met.

Why do we need you?

National Grid is the owner of the England & Wales High Voltage Electricity Transmission System and the Operator of the GB High Voltage Electricity Transmission System.

To operate the system on a real time basis National Grid requires access to a range of services.  These services are used to balance supply and demand, and to maintain quality and security of supply.

Services can generally be provided to National Grid in one of two ways, either an increase in generation or a reduction in electricity demand by parties connected to the GB Electricity Network.  These services being delivered by a range of different providers:

• Generating units (including back up generators)
• Large loads who reduce their electricity consumption
• Aggregation of smaller loads from a number of sites
