2 Hon. Kimberly D. Bose March 15, 2018 Page 2 I. BACKGROUND In its May 2012 Order, the Commission initiated an investigation pursuant to Section 206 of the Federal Power Act ( FPA ), 16 U.S.C. 824e, to determine whether the formula rate protocols in MISO s Tariff are sufficient to ensure just and reasonable rates. 4 After considering briefs filed by several parties, the Commission issued its May 2013 Order, finding that the formula rate protocols contained in MISO s Tariff are insufficient to ensure just and reasonable rates, and directing MISO and the identified MISO transmission owners to file revised formula rate protocols to enhance the scope of participation by interested parties, increase transparency in the information provided to interested parties, adopt procedures by which interested parties can challenge a transmission owner s implementation of its formula rate, and establish a requirement that MISO and transmission owners make an annual informational filing with the Commission. 5 With regard to the annual informational filing, the Commission required the submission of annual informational filings of [each transmission owner s] formula rate updates... following the time period allowed for parties to review the updates and for transmission owners to respond to information and document requests. 6 The Commission stressed that these filings would be just that, informational, 7 and that they are not themselves rates and do not constitute changes in the underlying rate itself. 8 In its March 2014 Order, the Commission require[d] all MISO transmission owners to submit informational filings in separate docket numbers. 9 The Commission also direct[ed] MISO to provide notification of the filing through the exploder list to be maintained by MISO, and by posting the docket number assigned to each transmission owner s informational filing on the MISO website and [Open Access Same-Time Information System ( OASIS )] within five days of such filing. 10 The Commission further directed that the informational filings contain information necessary to review the reasonableness of projected costs for transmission owners with forward-looking rates May 2012 Order at P 1. May 2013 Order at PP 1, Id. at P 92. Id. at P 92 n.142. Id. at P 85. March 2014 Order at P 71. Id. Id. at P 62.

3 Hon. Kimberly D. Bose March 15, 2018 Page 3 II. THE ANNUAL WHOLESALE TRANSMISSION FORMULA RATE UPDATE IS NOT A RATE CHANGE PURSUANT TO FEDERAL POWER ACT SECTION 205 AND DOES NOT ESTABLISH A NOTICE REQUIREMENT This Informational Filing is not a rate filing and does not change the Entergy Operating Companies transmission formula rate templates under MISO Tariff Attachment O, which constitute the Entergy Operating Companies rates for the development of their annual transmission revenue requirements. 12 Rather, this Informational Filing shows the development of the Entergy Operating Companies annual transmission revenue requirements for June 1, 2017 through May 31, 2018 through the application of data for Calendar Year 2016 to the Entergy Operating Companies transmission formula rate templates. 13 This Informational Filing also provides supporting workpapers. Because this Informational Filing is not a rate filing under FPA Section 205, a notice of filing is not required. Consistent with the requirements of their Annual Update Procedures, the Entergy Operating Companies will provide notice to customers and stakeholders through service of notice of this Informational Filing on customers and stakeholders and by posting the docket number for this filing on MISO s website and OASIS. III. INFORMATIONAL FILING Section VII of the Entergy Operating Companies Annual Update Procedures set forth in Attachment O of the MISO Tariff provides that, by March 15 of each year, the Entergy Operating Companies shall submit an annual informational filing to the Commission including information that is reasonably necessary to determine: (1) that input data under the Transmission Formula Rate Templates are properly recorded in any underlying workpapers; (2) that Entergy Services has properly applied the Transmission Formula Rate Templates and their Annual Update Procedures; 12 The Commission has made clear that annual formula rate updates and informational filings and [sic] are not themselves rates and do not constitute changes in the underlying rate itself (that is, the formula, which is the rate) and thus are not section 205 filings that require Commission approval. May 13 Order at P 85 (citation omitted). 13 Entergy Services notes that this Informational Filing includes information for Entergy New Orleans, Inc. ( ENOI ), which formerly was an Entergy Operating Company. On November 30, 2017, ENOI completed an internal restructuring transaction ( ENOI Internal Restructuring ), authorized by the Commission pursuant to FPA Section 203 in Entergy New Orleans, Inc., 159 FERC 62,264 (2017), in which substantially all of ENOI s assets and liabilities were succeeded to by Entergy New Orleans, a newly-formed, majority-owned indirect subsidiary of Entergy Corporation. The effect of the ENOI Internal Restructuring was to cause ENOI s public utility business to be owned by Entergy New Orleans. See Entergy New Orleans, LLC, Docket No. ER18-520, Notice of Succession (Dec. 22, 2017) (Entergy New Orleans succession to the tariffs and rate schedules of ENOI with a requested effective date of November 30, 2017). The data for Calendar Year 2016 for ENOI is presented in the populated Entergy New Orleans Attachment O.

4 Hon. Kimberly D. Bose March 15, 2018 Page 4 (3) the accuracy of data and the consistency with the Transmission Formula Rate Templates of the annual transmission revenue requirements under review; (4) the extent of accounting changes that affect Transmission Formula Rate Template inputs; and (5) the reasonableness of the actual and projected costs. The Informational Filing must also describe any corrections or adjustments made during the review period identified in the Annual Update Procedures, and must describe all aspects of the Transmission Formula Rate Templates or their inputs that are the subject of an ongoing dispute under the Annual Update Procedures informal or formal challenge procedures. In compliance with the Annual Update Procedures, an extensive informal review of each of the Entergy Operating Companies data and calculations for each of their respective annual transmission revenue requirements was undertaken. MISO participated in this review process, as did several interested customers. The review resulted in certain minor adjustments and corrections to the Entergy Operating Companies Attachment O formula input data. Those adjustments and corrections are described briefly below, and are detailed in the Attachment O calculations included in this filing and in item IV.5 listed below. Specifically, adjustments were made to reclassify certain amounts originally booked in FERC Account Miscellaneous Transmission Expense to other FERC Operations and Maintenance accounts. The amounts removed from Account 566 are as follows: Entergy Arkansas $ 277,616 Entergy Louisiana $ 613,758 Entergy Mississippi $ 195,255 Entergy New Orleans $ 75,144 Entergy Texas $ 214,927 Adjustments were also made to remove certain amounts booked in FERC Account The amounts removed from Account are as follows: Entergy Arkansas $ 39,382 Entergy Louisiana $ 61,679 Entergy Mississippi $ 22,044 Entergy New Orleans $ 11,644 Entergy Texas $ 21,535 Additionally, the following corrections were made: Entergy Arkansas Accounts 920 and 923 were revised by $689 and $2,848, respectively, to reverse the retail Fukushima deferral and amortization.

5 Hon. Kimberly D. Bose March 15, 2018 Page 5 Entergy Louisiana s Attachment O revenue requirement for the 2015 test year s amortization of the investment tax credit of $4,991,021 was corrected from a positive value to be a negative value. This correction resulted in a $2,532,522 revenue requirement decrease for the 2015 test year. After interest applied at the FERC rate, the true-up amount billed in the 2016 test year was adjusted lower by $1,529,189, with the remainder of the $2,621,466 total correction billed in In addition to the minor adjustments and corrections to the Entergy Operating Companies Attachment O formula input data resulting from the informal review process, certain other changes were made as a result of recent Commission proceedings in Docket Nos. ER and ER Specifically, as a result of the partial settlement agreement approved by the Commission in Docket Nos. ER and ER , 14 the following adjustments were implemented for each of the Operating Companies: Appendix A: Lines 152a were either added or revised. WP21 Pension: Column titles were revised to match Entergy accounting designations. WP22 IT Adj: The tariff workpaper was revised. WP22 Support: A non-tariff supporting workpaper with additional detail was added. Additionally, the following changes, which were contained in a March 14, 2018, errata filing submitted to the Commission under Docket No. ER to correct the versions of the Entergy Operating Companies transmission formula rate templates originally filed in Docket No. ER , 15 have been implemented as well: ADIT Account Functionalization Changes From To Companies : Supplemental Pension Plan-Fed Other Labor All except Entergy Texas : Supplemental Pension Plan-St Other Labor All except Entergy Texas : Regulatory Asset - Federal Transmission Other Entergy New Orleans : Regulatory Asset - State Transmission Other Entergy New Orleans : Pension - Federal Other Labor Entergy Louisiana : Pension - State Other Labor Entergy Louisiana Also: WP21 column headings were updated to reflect Entergy accounting designations. 14 See Entergy Ark., Inc., Docket Nos. ER , et al., Letter Order (Jan. 18, 2018) (approving offer of partial settlement) ( January 18 Order ). 15 See Entergy Ark., Inc., Docket No. ER , Errata Filing (Mar. 14, 2018) (submitting corrected versions of the Entergy Operating Companies transmission formula rate templates originally filed in Docket No. ER ). The Entergy Operating Companies submitted the corrected versions of their Attachment O templates as an errata filing to address limited issues in the template with respect to pension costs that have come to the Entergy Operating Companies attention during the course of ongoing hearing proceedings in Docket No. ER See id.

6 Hon. Kimberly D. Bose March 15, 2018 Page 6 The cumulative effect of all of these updates results in a decrease in the annual revenue requirement of each of the Entergy Operating Companies, except for Entergy New Orleans, whose updates resulted in an increase.
