Link Direct Testimony. In reference to Table 2 and Table 3 of the Link Direct Testimony, please provide versions of these benefits tables on a project-by-project basis for each Repowering Project.

Following questions refer to confidential workpapers:
Link Direct Testimony Workpapers. Regarding the project revenue requirements included in the “Repower Results Direct Testimony.xlsm” workpaper:
Please provide a detailed accounting of revenue requirements on a project by project basis.
Please provide a reconciliation of the annual revenue requirements for the repowering projects (see, e.g. row 89 of the “Price-Policy Annual – PaR” sheet) with the 20 year levelized values (see, e.g. row 62 of the “Price-Policy Annual – PaR” sheet. This reconciliation should demonstrate how these representations of project costs tie to the same set of project-by-project cost inputs. Please also provide a reconciliation of these values to the project-specific capital cost values included in Exhibit RTL-1.
Link Direct Testimony Workpapers. Regarding the Forward Price Curve Values provided in the Wind Project workpapers (e.g. “IRP Repower LGIA Limit v13 WIC LJ.xlsm”):
Please provide the source of the FPC values provided in this workpaper (Rows 127:131 of the ‘Existing’, ‘ExistRepwr’, and ‘Repower’ sheets).
Please explain all FPC discrepancies between the worksheets. For example, the Wyoming FPC values in the ‘Repower’ sheet are significantly lower than the values in the ‘Existing’ sheet.
Link Direct Testimony Workpapers. Regarding the Generation (MWHs) values provided in the Wind Project workpapers (e.g. “IRP Repower LGIA Limit v13 WIC LJ.xlsm”):
Please provide the source of the generation values provided in this workpaper (Rows 9:21 of the ‘Existing’, ‘ExistRepwr’, and ‘Repower’ sheets).
Please reconcile these values with the generation values provided in Exhibit RTL-1 and explain all discrepancies.
Please explain why some projects show a decrease in annual generation after repowering (see, e.g. Glenrock III).
