Energy Division California Public Utilities Commission May 14, 2018 Page 2 II. Discussion A. Response Regarding Content of SCE’s Proposed Work Plan Contrary to ORA’s assertion, SCE does not believe its work plan overemphasizes its “general distribution planning process.”2 SCE’s distribution planning process is the central foundation for the data contained in the GNA and DDOR, and establishing a plan to enable this process to support the GNA and DDOR reporting requirements is a critical aspect to achieving “the data compilation and reporting capabilities needed to complete the annual GNA and DDOR exercise.”3 The milestones presented in SCE’s work plan represent the completion of tasks in the annual distribution planning process because these tasks provide the inputs needed to compile the GNA and DDOR reports. ORA also asserts that while “SCE’s work plan appears well developed,” ORA would prefer more information concerning “the development and implementation of data compilation and reporting capabilities.”4 The compilation and formatting of SCE’s initial GNA and DDOR will consist of a largely manual process that leverages outputs of the annual planning process, combined with LNBA results, and the output of additional analysis to create forecasted profiles to quantify the frequency and magnitude of needs. While SCE will seek out opportunities to streamline the level of effort, this manual process will continue to be utilized until SCE is able to fully implement future software capabilities in its Long-term Planning Tool, specifically the forecasting, power flow and capacity analysis, project portfolio development to meet grid needs, and integrated reporting engine. The manual data compilation and reporting effort includes extracting data that describes the grid needs, planned investments, and candidate deferral projects from SCE’s planning databases as they become available as corresponding milestones in the annual planning process are completed. SCE will then manually compile, and format the fields in Microsoft Excel to publish the final reports. B. Response Regarding ORA’s request for Workshop and Format Changes ORA recommends that the Commission reject the Advice Letters, hold a workshop to establish a common format across utilities for the GNA and DDOR beginning with the 2018 DDOR and the 2019 GNA filings, and require that the Utilities clarify their work plans and milestones.5 SCE disagrees with this recommendation and requests that the Commission approve Advice 3787-E, as the Advice Letter is consistent with the directive of the Decision and the requirements laid out in Section 3.4.1.6 2 3 4 5 6 ORA Protest, at p. 3. D.18-02-004, at Ordering Paragraph No. 2.k. ORA Protest, at p. 3. Id, at p. 1. D.18-02-004, at p. 35-39.

Energy Division California Public Utilities Commission May 14, 2018 Page 3 Workshops are not necessary and may in fact create delays in achieving the September 1, 2018 DDOR deadline, especially with the many other requirements driven by the DRP for 2018 implementation.7 The Decision does not require that the utilities have consistent formatting and SCE notes that difference in the proposed formats may allow stakeholders to evaluate various options to determine the most effective format. In addition, the three IOUs have slightly different ways of referencing their distribution systems, performing analysis, and currently have varying planning software capabilities. SCE acknowledges the value of a consistent format for users of the GNA and DDOR reports; however, it is premature to establish a single, common format. Allowing the utilities to publish their 2018 DDOR reports using the proposed formats in their respective Advice Letters would allow stakeholders to compare various formats to better inform recommendations towards a common format in future iterations as deemed appropriate by the Commission. III. Conclusion SCE thanks the Commission for the opportunity to provide these reply comments to the ORA Protest of Advice 3787-E. Sincerely, /s/ Gary A. Stern, Ph. D.. Gary A. Stern, Ph. D.
