Fast Frequency Response - Available Volume, Payment and Performance Assessment. The basis for payments for Fast Frequency Response (FFR) is the calculation of the FFR Available Volume of the Providing Unit over a Trading Period. The MW Output or MW Reduction and Availability of the Providing Unit for the Trading Period form the basis for calculating FFR Available Volume. The payment for the Trading Period shall be adjusted by the FFR Scaling Factor of the Providing Unit.
Fast Frequency Response - Available Volume, Payment and Performance Assessment. Fast Frequency Response (FFR) is the additional MW Output or MW Reduction required compared to the pre-incident MW Output or MW Reduction, which is fully available from a Providing Unit within 300 ms after the start of an Event and sustainable up to 10 seconds after the start of the Event. The extra energy provided in the 0.3 to 10 second timeframe must be greater than any loss of energy in the 10 to 20 second timeframe due to a reduction in MW Output or MW Reduction below the pre-incident MW Output or MW Reduction.
