We are becoming a separate company

In April 2019, the Electricity System Operator is becoming a separate company within the National Grid Group. Find out more about what this change will mean.

Firm frequency response (FFR)

FFR creates a route to market for providers whose services may otherwise be inaccessible. The FFR service gives us and service providers both a degree of stability against price uncertainty under the mandatory service arrangements.

How to tender

FFR is procured through a monthly electronic tender process. Once service providers succeed in the pre-qualification assessment and sign onto a framework agreement, they will be provided with a login to the electronic tender platform.  Providers can then tender in for a single month or multiple months. 

Having considered the quality, quantity and the nature of the services, we will accept the most economical tender(s). A successful tender then becomes contractually binding.
