As such, these factors are split amongst the three components on a weighted basis based on how they relate to different operations of the company. Energy – energy components are factors which relate directly to costs of energy provided to customers, including fuel and fuel-related components. Customer – customer components are factors which relate directly to individual customer accounts, including meter reading, billing, customer account record keeping, supplying o customer information, and associated administrative overhead costs. Facilities which are put in place specifically to serve a particular customer also are considered customer components. Classifications Demand – demand components relate to the fixed capacity portions of systems used to provide electricity to customers, including production, transmission, distribution substation primary distribution and secondary distribution systems, and line transformers.

The system spans a 52,000 square mile area in the Texas Panhandle through West Texas and Eastern and Southeastern New Mexico. SPS has generation on both 230 kV and 115 kV busses throughout this area. SPS determines the demand and energy losses for the following components: Unit Main Transformers Transmission Lines Autotransformers Distribution Substation Transformers Distribution System, including Primary, Secondary, Services and Line Transformers Please refer to Schedule P-9 for the demand and energy loss factors used to assign the cost of service responsibility for the Base Period and Future Test Year. Please refer to the direct testimony of John S. Fulton for the complete line loss study and the current line loss factors presented in this proceeding. The analysis of losses requires consideration of both demand or power losses and energy losses. The demand losses are typically measured in megawatts (MW), kilowatts (kW), or watts. The energy losses are measured in megawatt-hours (MWh), kilowatt-hours (kWh), or watt-hours (Wh). The energy losses can be thought of as the sum of instantaneous demands over a specified period of time, such as an hour. Certain components of the energy losses are present even though there is very low electrical load passing through the device. An example of this is the magnetizing current and related losses of a transformer. Once the transformer is energized, these losses are present. Power flow through the transformer will increase the losses, but the transformer will also have the no-load loss component. To provide a basis for the calculations, data is gathered for the transmission and distribution system. In some cases, engineering approximations are made, as appropriate, in the absence of specific data. One source of confusion in any loss evaluation is the comparison of the accounting values of energy losses, "Unaccounted For Energy", and the energy losses determined by a technical evaluation. Considerable technical data exists showing generation and power purchases on a calendar month basis. This represents the energy that was generated or procured for serving the customer load in a given month. However, SPS bills customers each normal working day. Therefore, sales recorded in a specific month may have been delivered to the customers during parts of the two previous months and the current month whereas net output or generation is measured coincident with the billing month. When all sales are totaled and compared to that billing month's Schedule M-3 Page 2 of 2 Sponsors: Fetters, Fulton Case No. 15-00139-UT generation and power purchases, the "Unaccounted For Energy" can be a small positive or negative number. This difference does not reflect the actual losses incurred on the transmission and distribution system during the billing month. To minimize this effect, it is necessary to reconcile energy losses and the "Unaccounted For Energy" over a longer time, such as a twelvemonth period. (c) Explanation of Adjustments The demand and energy loss factors used in the Future Test Year are the same as the Base Period. No adjustments were made.
