REQUEST:
In its 2015 rate case (AVU-E-15-05), the Company based its Cost of Service allocators on a Load Research Study performed by DNV-GL (dated January 22, 2015). For the present case (AVU-E-16-03), were the Cost of Service allocators based on the same study? If not, please provide the information used as a basis for the allocators used in the present case.
RESPONSE:
The Knox Cost of Service workpapers included the demand study results as pages COS-127 through COS-130. The native format Cost of Service workpapers included a file named “Demand 12CP 12.2015.xlsx” that contains the calculation of the demand-related allocation factors used in this case. The relationships and load shapes from the Load Research Study are used in combination with 2015 usage and customer data to determine the 2015 specific demand study results. For your convenience a copy of the demand study included with the native format workpapers is provided here as Staff_PR_041 Attachment A.
