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.

Asset testing

Providers will need to test their assets in accordance with the testing procedure below. For further information please contact your Account Manager. 

This is currently being reviewed and streamlined following our consultation.
