A reconciliation between test year and proforma amounts allowed into rates and the actual expenditures for each test year and proforma, related to all distribution and transmission expenditures for each of the listed GRCs, is not available.

The table below provides the filed historical test period included in each GRC referenced docket between 2011 and 2016, as well as the level of capital additions (or net plant) approved, by year, per GRC.

Please see Staff_PR_126 Attachment A for transaction detail by FERC account for Distribution and Transmission O&M Expense for the period 2010-2015. Due to the voluminous nature, this data is provided in electronic format only. See Staff_PR_126 Attachment B for capital costs for the period 2010-2015. Attachment B includes common and electric system transfers to plant by FERC account. This information is not reconciled by the GRC it is included in, however, the table above shows the year in which expenses and capital would have been included in each of the above referenced dockets.

See Company witness Ms. Schuh’s filed exhibits in this proceeding: Exhibit No. 10, Schedule 3 (for proposed transmission/distribution capital project amounts for 2016 and 2017) and Schedule 4 (2016 and 2017 capital project business cases) in support of the 2016 and 2017 capital additions proposed in the Company’s filing.
