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.
Types of payment structure
Paid per hour (£/hr) - for the hours for which a provider has tendered to make the service available for.
Window initiation fee (£/window) - for each FFR nominated window that we instruct within the tendered frames.
Nomination fee (£/hr) - a holding fee for each hour used within FFR nominated windows.
Tendered window revision fee (£/hr) - we notify providers of window nominations in advance and, if the provider allows, this payment is payable if we subsequently revise this nomination.
Response energy fee (£/MWh) - based upon the actual response energy provided in the nominated window.
- As per CUSC section 126.96.36.199A for BMU Providers.
- Tendered parameter for Non-BMU Providers.
Utilisation volumes will be determined in accordance with system frequency and the characteristic of the response service.
