1 NIPSCO Aggregate 206 True-up Calculations Instructions: Inputs are indicated by light yellow highlighted cells with blue bold font. For "Company Name" be sure to use our standard abbreviations or check the last tab titled "List of ROE by TO" Purpose: To calculate the 206 Attachment O, GG, and MM True-up weighted for the two different ROEs in effect during 206 Interest Rates Monthly Rate Annual Rate Int Rate on Over-Recovery (FERC) (four decimal places) 0.292% % Int Rate on Under-Recovery (ST Debt) (four decimal places) %.594% 206 ROE Weightings - Schedule 9, 26 & 26A Per FERC's 9/28/6 Order in EL4-2, the ROE was revised from 2.38% to 0.32% (plus adders as applicable) effective 9/28/6. The table below calculates the percentage of the year 206 applicable to each ROE. These percentages are used to prorate the 206 revenue requirement System Load * Days in Month Weighted Load In Month Effective by Month January 2, ,727 February 2, ,665 March 2,55 3 2, % April 2, ,446 May 2, ,894 June 3, ,404 July 3,57 3 3,57 August 3, ,603 26,884 September , % September % October 2, ,556 November 2, , December 2,74 3 2, % Total 34, , % * Monthly Peak Load (MW) as reported in FERC Form, page 400a, column b.
