Today’s LiveWire Spotlight looks at NERC’s 2021 Frequency Response filing with FERC – the first year that the BAL-003-2 method is used to derive the four North American Interconnection Frequency Response Obligations (IFROs). The new method ends the five-year “semi-freeze” in IFRO assignments initiated in 2016 to prevent substantive overstatements in the Eastern, Western, and Texas Interconnections.
By March 1, the ERO Enterprise will post FRS Form 1 with all selected events for the operating year for BA usage. By April 1, BAs must submit their completed frequency response forms for all four quarters, including their Frequency Bias Settings, to the ERO.
