Bose Secretary Federal Energy Regulatory Commission 888 First Street, NE Washington, D.C. 20426 Re: Informational Filing Regarding 2017 Frequency Response Annual Analysis Report Docket No. RM13-11-000 Dear Ms. Bose: The North American Electric Reliability Corporation (“NERC”) hereby submits its 2017 Frequency Response Annual Analysis Report (“Report”) for the administration and support of Reliability Standard BAL-003-1.1 – Frequency Response and Frequency Bias Setting. The Report updates statistical analyses and calculations in the 2012 Frequency Response Initiative Report, which was included with NERC’s petition for approval of Reliability Standard BAL-003-1 following subsequent reports filed under docket no.RM13-11. 1 The attached Report uses data from the operating years 2013 through 2016 (December 1, 2012 through November 30, 2016) to (i) analyze frequency events and interconnection frequency characteristics for BAL-003-1; and (ii) determine adjustment factors for calculating Interconnection Frequency Response Obligations (“IFROs”). This information is provided for consistency of the IFRO 1 See generally, filings submitted in the above captioned docket (these materials commonly refer to the standard as BAL-003-1, although BAL-003-1.1 is the latest version and currently-effective). The 2012 Frequency Response Initiative Report was attached as Exhibit F to the original petition submitted on March 20, 2015.
