Protocols Definitions (cont’d)– “Annual Update”
The Projection and True-Up process is referred to as the Annual Update. By May 15 of the current year, calculate the projected ATRR, and transmission
rates for the next Rate Year (the “Projection” and herein, the “2015 Projection”) and Schedule 1 rate for the next Rate Year in accordance with the Formula Rate.
• Based on the most recent FERC Form No. 1 data, limited projections of current calendar year transmission plant and long-term firm loads in Attachment 9A to the Formula Rate will be adjusted.
By May 15, calculate the True-Up for the preceding calendar year in accordance with the Formula Rate (the “True-Up” and herein, the “2014 True-Up”).
• Shall include actual data for the prior calendar year compared to the data projected in the Annual Update for the same calendar year - a refund or surcharge shall be issued to customers including interest.
– “Publication Date” Informational filing with FERC by May 15 of the Annual Update and information
posted to OASIS showing the calculation of such Annual Update (the date of such posting is referred to herein as the "Publication Date");
Notification of refund or surcharge notices sent to customers. – “Information Request Period”
Up to 180 calendar days after the Publication Date, Interested Parties may submit requests for information supporting the Annual Update.

Formula Rate Fixed Assumptions
Major fixed assumptions in the Formula:
- Stated ROE of 9.8%
- Incentive ROE of 0.5% applied to Energy Gateway projects
- BoY-EoY or 13-month averages for the true-up and end-of-year balances for the projection of some ATRR components (e.g., Transmission PIS)
- Equity Ratio is capped at 53%
- Allocators used to calculate certain transmission-related expenses

Allocators have varying effects on the Formula rate inputs2014 True-Up • Gross Plant allocator decreased because Transmission Gross Plant
grew slower than Electric Plant in Service (0.18% vs 2.73%) • Net Plant allocator decreased primarily because accumulated
depreciation grew faster than additions to the total plant in the rate base 2015 Projection • Gross Plant and Net Plant allocators increased because Transmission
Net Plant grew faster than Electric Plant in Service

Investment Return: Rate Base - Net PP&E
Net PP&E
2014 True- Up: Net PP&E did not change significantly. The decrease was primarily attributable to higher accumulated depreciation, partially offset by higher allocated portion of general and intangible assets to transmission

Investment Return: Rate Base: Net PP&E (cont’d)
2015 Projection– Increase in Net PP&E primarily due to increase in Total Plant
in rate base (+7.69%), partially offset by increased Accumulated Depreciation and Amortization balances (+5.83%)
– Forecasted additions: Energy Gateway $340.8m Sigurd to Red Butte segment $4.42m incentive added for Energy Gateway transmission
projects– Other Transmission PIS
$38.4m Carbon plant system reinforcement $177.7m of multiple other large and small investments
originated to meet NERC standards and transmission contractual obligations

base versus 2014 Projection– Changes in ADIT are largely the result of normal activity over 2014

Investment Return: Rate Base Adjustments (cont’d)
Network Upgrade Balance (Line 50):
– Decreased (i.e., less negative) Network Upgrade Balance lowers rate base versus 2014 Projection
– Decreased due to refunds of approximately $8.9 million for interconnection projects, offset by additional network upgrade construction costs of approximately $3.0 million
Materials & Supplies Allocated to Transmission (Line 46):
– Increased (i.e., more positive) materials and supplies expenses increases rate base versus 2014 Projection
– Increase is primarily due to increased construction materials and supplies balances

Transmission O&M (Line 56)– The increase of $14.9m in Total Transmission ( Line 53) from 2014 Projection includes:
Reclassification of $5.5m of NERC, WECC and NTTG membership dues from FERC 930.2 (Misc. General Expenses) to FERC 561.8 (Reliability, Planning and Standards Development)
Reversal of $1.7m of CWIP balances for Wallula to McNary 230 KV line project previously recorded in FERC 573 (Maintenance of misc. transmission plant)
– Transmission O&M decreased ~$1.1 primarily due to higher adjustments for FERC 565 (Transmission by others) and ancillary service FERC accounts 561.0-561.5 (Schedule 1 accounts) which are then subtracted from total Transmission O&M expenses resulting in an overall decrease of expenses in the rate base.

primarily due to reclassification of $5.5m of membership dues to FERC 561.8 account
$2.3 million – Outside Service Employed (FERC 923) due to lower legal consulting services
Decreases were partially offset by $ 4.7m more transferred Administrative Expenses (credit) (FERC 922)
– Adjustments to A&G (subtractions) Increases in Property Insurance (FERC 924) and Regulatory
Commission Expense (FERC 928) accounts, total $3.3 million increase in the adjustment (i.e., higher deduction from total A&G)

EIM cost
– Energy Imbalance Market (“EIM”) costs (see Enclosure 8) $994,615 capital cost allocated to Transmission
$653,303 (FERC 560, 561, and 569) in Transmission O&M
$443,995 (FERC 928) in Directly Assigned A&G
– Clarifications Details in Enclosure 8 for EIM-related charges should have
included additional expenses of $44,973 in FERC 560 and $30,973 in FERC 561 that were incurred after the project “go live” date. This results in $653,303 of total EIM-related expenses included in Transmission O&M (vs. $577,667 presented in Enclosure 8).
