Instructions1. Enter electricity portfolio names in cells Q27-V27, as needed.2. Enter the megawatt hours (MWh) of retail sales associated with electricity portfolios in cells Q25-V25, as needed, and the MWh associated with other end uses in cell W25.3. In the table beginning with cell A28, enter information about all specified purchases. All fields in white should be filled out. Fields in grey auto-populate as needed and should not be filled out.4. Default loss factors will auto-populate based on resource location. Enter a custom loss factor if applicable. All custom loss factors require additional documentation.5. If a resource’s losses are covered by the generation seller under contract, select “Yes” in the relevant cell in column M: “Specified Losses Covered by Seller?” 6. For firmed-&-shaped procurements specifically, enter all fields from step 3. Additionally, enter the EIA ID of the substitute power in the "EIA ID of Delivered Energy" field.7. For firmed-&-shaped procurements eligible for grandfathered GHG emissions, select "Yes" in the relevant field in column L: "Eligible for Firmed & Shaped Grandfathering?"8. Proxy EIA IDs for unspecified power and specified system mixes from asset-controlling suppliers have been provided. Enter "Unspecified Power", "BPA", or "Tacoma Power" as applicable.9. Proxy EIA IDs for aggregated reporting of WAPA CVP or PCIA resources have been provided. Enter "CVP", "PCIA Solar", "PCIA Wind", "PCIA Eligible Hydro", or "PCIA Large Hydro" as applicable.10. Only unspecified imports purchased directly from a seller under contract or ACS unspecified power procurements must be entered as line items; any additional unspecified power is calculated automatically in individual electricity portfolio tables after all specified resources are allocated.11. Allocate net MWhs procured to each electricity portfolio until the loads are balanced across each portfolio. If the total Net MWhs Procured exceeds the total retail sales of all portfolios, allocate only enough MWh to meet the retail sales of each portfolio.12. If electricity portfolio loads are balanced and net MWhs remain, allocate net MWhs to cover losses in the column starting with cell X28. This will add new losses, resulting in a new net short of unmet load in Cell X26. For retail suppliers that want to cover 100% of their lossadjusted load with specified procurements, continue allocating specified procurement in Column X until Cell X26 shows no unmet load.

This Secondary Losses Adjustment Calculator is used for alternative loss factors (rather than the default loss factors). The calculator adjusts a generator-based loss factor so that it calculates primary and secondary losses. Enter the generator-based loss factor in cell B7 to get the adjusted loss factor in ce Using the most recent EIA 861 data, line losses were calculated at 4.19% for in-state resources and 6.19% for imported resources. These values are based on Total Energy Supply, which includes Estimated Losses (this is a top-down calculation).That total supply-based loss factor must be converted to a loss factor that can be applied only to the generation matched to load, rather than total supply. The Calculation of Default Loss Factors section below provides the necessary calculations.The corresponding bottom-up loss factors that will gross up load-matched resources to determine losses are 0.0437 and 0.0660, respectively. This conversion does not increase losses, which can be demonstrated below, as [Cell B14 x Cell B18] = [Cell B22 x Cell B23].
