A detailed analysis of the City's customer billings for the months of November and December 2018 and February and March 2019. www. greeneforensicas.com 4 Summary of Results (Forensic Audit Report Page References Included) 1. The City employs a classification system for city utility customers. The classification system is inconsistently applied, and the definition of a residential customer is confusing (p. 6). The City does not appear to have a detailed database to support the Equivalent Residential Units (ERUs) being charged to customers (p. 21). 3. ERUs do not appear to accurately estimate customer Water and Sewer consumption (p. 24). 4. The City is not charging eligible large customers a power factor adjustment, even though the charge has been consistently required per each annual tariff (p. 30). There are numerous discrepancies in the detailed customer charges for the four test months (p. 38). www. greeneforensicas.com Customer Classification (P• 5) ► Customer Characteristics vs Consumption (p. 10). ► Water/Sewer charges are generally based on Customer Characteristics (Except for Metered Users). ► Electric charges are generally based on Consumption. ► Exhibits: ► B - Seward Tariff Comparison (p. 236). ► C - Water/Sewer Utility Classification by Customer Characteristics (p. 239). ► Residential Service (p. 11). ► Water/Sewer vs. Electric. ► Rates vary for Electric customers. ► Electric Department proposing separate invoicing for Electric Customers. ► Residential Home Occupations (p. 14). ► Definition of "Owner". ► Auditor Conclusions on Residence (p. 17). ► Common Laundry Facilities Example (p. 18). ► Exhibits: ► D - Electric Department Demand Policy (p. 241). ► E - Residential Service Definitions and Descriptions (p. 244). www.greeneforensicas.com Equivalent Residential Units (ERUs) ► Customer Database of ERUs (p. 21). ► The City has a database showing the number of ERUs being charged to each Customer, but not the rationale supporting the number of ERUs. ► There appears to be no formal method for updating ERU counts (See note on Schedule F). ► Customers do not appear to understand the basis of ERU charges. ► No adjustment process for business changes or events such as the Pandemic. ► ERU Testing (p. 22). ► Schedule F—Test Results (p. 257). ► Meters vs. ERUs. ► Limited Testing indicated that ERUs were not accurately estimating large customer usage. ► Exhibits: ► G-1 to G-6 ERU vs. Meter Comparison (p. 262). www. greeneforensicas.com Power Factor (p. 30) ► Power Factor Rate is in the Electric Tariff. ► Not being charged to eligible Large Customers. ► Has been evaluated by former Electric Department Management. ► Charges would impact several businesses based on prior evaluations. ► City meters are not calibrated to measure the Power Factor per the Electric Department Director. ► Chugach is measuring City's Power Factor.
