6 FINANCIAL AND OPERATING RATIOS OF PUBLIC POWER UTILITIES
This report presents data for 21 categories of financial and operating ratios for 138 of the largest publicly-owned electric utilities in the United States. The ratios can be a useful tool in assessing electric utility performance. However, they do not provide definitive information, nor should the level of any indicator be taken as the “correct” level of performance.
It is important that users be familiar with definitions of ratios and the variables that can affect them. Although the groupings of the ratios by customer size class, region and net power generation adjust for major variables, other factors might also influence the ratios. The financial and operating ratios provide a useful starting point for analyses and may be used to pinpoint areas in need of further investigation. The ratios should be analyzed in conjunction with other information and should not be the sole basis for broad conclusions.
A new ratio has been added to this report: Capital Expenditures to Depreciation Expenditure. This ratio was added on a pilot basis and is subject to modification based on feedback from participants.
A. Report FormatSummary tables listing median values of the ratios are presented in Section II by customer size class, region and net power generation. Section III presents detailed breakdowns for each ratio with the number of utilities, means, medians and first and third quartile values. The information is provided by customer size, region and generation groupings. Definitions and descriptive information precede each set of tables. A copy of the American Public Power Association’s 2017 Performance Indicators Survey, as well as formulas, data sources, definitions of regions, and the utilities included in the report can be found in Appendices A, B, C and D.
Medians and number of responses for each ratio are presented in the following table for all customer size classes, regions and generation classes.
INTRODUCTION
FINANCIAL AND OPERATING RATIOS OF PUBLIC POWER UTILITIES 7
B. Utilities in the ReportThe utilities included in this report are those that responded to the Association’s 2017 Performance Indicator Survey. The survey was sent to all public power utilities with sales to consumers that account for approximately 50 percent or more of total sales, and that also have retail sales or sales for resale of 100,000 megawatt-hours or more.
Direct comparisons with the 2016 ratio report should not be made because the composition of utilities included for each ratio might have changed. Although 138 utilities are included in this report, not all of the utilities were incorporated into each of the ratios. Many utilities did not have, or did not provide information necessary for,
particular ratios. Also, data were excluded from calculations if there was reason to believe the information is incorrect (e.g., extreme values).
The respondents are grouped into six customer size classes. Mean, median, and first and third quartile values are calculated for each of these classes. Means are weighted means - calculated by summing the values for all utilities, and then computing the ratio from these totals. Since large utilities heavily influence the mean value (particularly when there are only a small number of utilities in the sample), median values provide a better measure of the typical utility.

C. Definitions, Data Sources and ComputationsDefinitions of each ratio are found in Section III, Detailed Tables, and information on data sources and computations is provided in Appendix B. The data in this report come from two sources: the Department of Energy, Energy Information Administration (EIA) report Form EIA-861; and the Association’s 2017 Performance Indicators Survey.
D. Factors Influencing RatiosEach of the ratios in this report might be influenced by a variety of economic, environmental and technical factors. Aggregating the data can mask significant differences. When making comparisons, users of the data should attempt to understand the various factors that might affect a particular ratio. A high or low value for a given ratio for an individual utility, relative to the median for a group, might be due to particular policies or situations faced by a utility, and might not be indicative of a performance problem.
The groupings in this report adjust for differences in utility size based on the number of customers served, regional variations, and differences in operations related to the proportion of power requirements generated by the utility. Factors that might influence the ratios include:
• Number and composition of customers served;
• Geographic location;
• Population density;
• Source of power supply (and physical, economic, or institutional barriers to acquiring alternative power supply);
• Amount of taxes, payments in lieu of taxes, contributions and free electricity or services that a utility makes to or receives from a local government;
• Number of contract employees used by a utility (e.g., consultants, contract labor for maintenance, tree trimming);
• Financial policies (e.g., proportion of major capital expenditures financed by long-term debt versus current revenue);
• Management policies (e.g., the extent to which a utility focuses on customer service or other programs);
• Regulatory policies;
• Relatively small number of utilities reporting data on a particularratio (e.g., small numbers of utilities frequently appear in the detailed breakdowns);
• Degree of precision of the data component; or
• Differences in utility reporting periods.
Ratios are calculated from fiscal year and calendar year data.
10 FINANCIAL AND OPERATING RATIOS OF PUBLIC POWER UTILITIES
The following tables present summary data on the 21 financial and operating ratios by customer size class (Table A), by region (Table B), and by generation class (Table C). These tables present median values for each of the ratios. Definitions and detailed data including means, medians and quartile values appear in Section III. Data sources and calculation procedures are found in Appendix B.
The average number of retail customers reported by each utility on the Performance Indicators Survey determines customer size class. Responding utilities are grouped into five geographic regions: Northeast, Southeast, North Central/Plains, Southwest, and West. The regions correspond to combined regions of the North American Electric Reliability Council (NERC). See Appendix C for a detailed description of the regions.
Generation refers to the power a utility produces and is based upon the utility’s net generation as a percent of total sources of energy as reported on the Performance Indicators Survey.

14 FINANCIAL AND OPERATING RATIOS OF PUBLIC POWER UTILITIES
The following tables present a detailed breakdown of each of the 21 ratios. Each table includes a breakdown of the ratio by customer size class, region, and generation class. The numbers of responses are presented along with the mean, median and first and third quartile values of the ratio for each class.
1. Revenue per Kilowatt-houra. All retail customers – The ratio of total electric operating revenues from sales to ultimate customers to total kilowatt-hour sales. This ratio measures the amount of revenue received for each kilowatt-hour of electricity sold to all classes of customers, including residential, commercial, industrial, public street and highway lighting and other customers.
b. Residential customers – The ratio of residential revenues to residential sales. This ratio measures the amount of revenue received for each kilowatt-hour of electricity sold to residential customers.
c. Commercial customers – The ratio of commercial revenues to commercial sales. This ratio measures the amount of revenue received for each kilowatt-hour of electricity sold to commercial customers.
d. Industrial customers – The ratio of industrial revenues to industrial sales. This ratio measures the amount of revenues received for each kilowatt-hour of electricity sold to industrial customers.
The definitions of commercial and industrial customers can vary between utilities, with the resulting classification based on specific load characteristics or demand rather than on a popular definition of “commercial” or “industrial.” Revenue and sales data include only full-service (bundled sales), thus data for customers who purchase power from an alternative supplier are excluded.
More detailed revenue per kilowatt-hour data, including data for all retail electric utilities in the United States, can be found on the statistics page of the Association’s website at www.PublicPower.org/public-power/stats-and-facts/industry-statistics-and-reports.

2. Debt to Total AssetsDefinition: The ratio of long-term debt, plus current and accrued liabilities, to total assets and other debits. This ratio measures a utility’s ability to meet its current and long-term liabilities based on the availability of assets.
Long-term debt includes bonds, advances from the municipality, other long-term debt, any unamortized premium on long-term debt and any unamortized discount on long-term debt. Current and accrued liabilities include warrants, notes and accounts payable, payables
to the municipality, customer deposits, taxes accrued, interest accrued, and miscellaneous current and accrued liabilities. Total assets and other debits include utility plant, investments, current and accrued assets and deferred debits.
This ratio might be influenced by the extent to which its components include information applicable to the non-electric portion of the utility, if any (e.g., gas, water). In addition, the ratio might be influenced by a utility’s financial policies.

4. Current RatioDefinition: The ratio of total current and accrued assets to total current and accrued liabilities. This is a measure of the utility’s short-term liquidity (the ability to pay bills). The current ratio takes a snapshot of the utility’s liquidity at a point in time and thus might vary considerably at other times of the year.
5a. Times Interest EarnedDefinition: The ratio of net electric utility income, plus interest paid on long-term debt, to interest on long-term debt. This ratio measures the ability of a utility to cover
Total current and accrued assets include cash and working funds, temporary cash investments, notes and accounts receivable, receivables from the municipality, materials and supplies, prepayments and miscellaneous current and accrued assets. Total current and accrued liabilities include warrants, notes and accounts payable, payables to the municipality, customer deposits, taxes accrued, interest accrued and miscellaneous current and accrued liabilities.

5b. Debt Service CoverageDefinition: The ratio of net revenues available for debt service to total long-term debt service for the year. This ratio measures the utility’s ability to meet its annual long-term debt obligation.
6. Net Income per Revenue DollarDefinition: The ratio of net electric utility income to total electric operating revenues. This ratio measures the amount of income remaining after accounting for operation and maintenance expenses, depreciation, taxes and tax equivalents for every dollar received from sales of electricity.
Net revenues available for debt service equal net electric utility operating income (operating revenues minus operating expenses) plus net electric utility non-operating income, plus depreciation. Debt service includes principle and interest payments on long-term debt.
This ratio might be influenced by a utility’s financial policies.
The ratio might be influenced by the type and availability of power supply options and by the amount of taxes and tax equivalents that a utility transfers to the municipality or other governmental body. Financial policies and the amount of debt can also affect this ratio (e.g., how a utility finances capital investments).

8. Retail Customers per Non-power-generation EmployeeDefinition: The ratio of the average number of retail customers from all classes to the total number of full-time, part-time and contract employees not involved in the generation of power. This ratio measures the average number of customers served by each non-generation employee.
The ratio might be influenced by the mix of customers and by population density. It will be influenced by the extent that employees shared with other (non-electric) departments are not properly prorated, or that employees involved in resale transactions are included. Part-time employees are assumed to work half-time (i.e., two part-time employees are counted as one full-time employee). To the extent that this assumption is violated, the ratio will be biased. Contract employees include only those individuals performing regular utility work on an ongoing basis.

9. Total Operation and Maintenance Expense per Kilowatt-hour SoldDefinition: The ratio of total electric utility operation and maintenance expenses, including the cost of generated and purchased power, to total kilowatt-hour sales. This ratio measures average total operation and maintenance expenses associated with each kilowatt-hour of electricity sold, either for resale or to ultimate customers.
Included in operation and maintenance costs are the expenses associated with power supply (generation and purchased power), transmission, distribution, customer accounting, customer services, sales, and administrative
and general functions of the electric utility. Because power supply expenses typically comprise the largest component of total operation and maintenance expenses, this ratio might be influenced by the proportion of power generated by a utility and the availability of alternative power supplies. Kilowatt-hours of electricity produced but not sold (i.e., energy furnished without charge), energy used internally, and energy losses are not included in the denominator.

10. Total Operation and Maintenance Expense (Excluding Power Supply Expense) Per Retail CustomerDefinition: The ratio of total electric utility operation and maintenance expenses, excluding all costs of power supply, to the total number of ultimate customers.
Operation and maintenance expenses include the costs of transmission, distribution, customer accounting, customer services, sales, and administrative and general expenses. The costs of power supply (generation and purchased power) are excluded from the ratio. This ratio can be affected by population density and the mix of customers between various classes (residential, commercial, industrial or other). Also, the extent to which a utility services resale customers will influence the ratio.
FINANCIAL AND OPERATING RATIOS OF PUBLIC POWER UTILITIES 25
11. Total Power Supply Expense per Kilowatt-hour SoldDefinition: The ratio of the total costs of power supply to total sales to both ultimate and resale customers. This ratio measures all power supply costs, including generation and purchased power, associated with the sale of each kilowatt-hour of electricity.
The ratio includes operation and maintenance costs arising from all generation types, including steam, nuclear, and hydraulic generation. Operation and maintenance
expenses include the costs of fuel, labor, supervision, engineering, materials and supplies, and purchased power. The ratio might be influenced by the geographic location of the utility, the availability of alternative power supplies, the degree to which the utility can generate its own power, and access to transmission. The ratio does not include kilowatt-hours produced but not sold (i.e., energy used internally, energy furnished without charge, or energy losses).

12. Purchased Power Cost per Kilowatt-hourDefinition: The ratio of the cost of purchased power to the number of kilowatt-hours purchased. This ratio measures the purchased power component of power supply costs.
Purchased power includes purchases from investor-owned utilities, municipalities, cooperatives or other public authorities for subsequent distribution and sale to ultimate customers. It does not include power exchanges.
Adjustments to the cost data were made in a small number of cases to eliminate power exchanges. The cost reflects the amount billed, including adjustments and other charges.
The ratio might be influenced by the geographic location of the utility, availability of alternative power supplies, access to transmission, and the type of purchase agreement, such as firm power, economy power, or surplus sales.

13. Retail Customers per Meter ReaderDefinition: The ratio of retail customers to the number of meter readers employed by the utility. This measures the average number of retail customers served by each meter reader.
The number of meter readers includes the total number of full-time meter readers plus half of all part-time meter readers. It is assumed that all part-time employees work half-time (i.e., one full-time employee is equivalent to two part-time employees). Population density, frequency of meter readings, and the technology or methods used to read meters will influence the ratio.
As more utilities implement advanced meters that can read customer data without having to send a meter reader to the customer’s residence or business, utilities require
fewer meter readers to cover their service territories. Some utilities have installed advanced meters in all of their service territory and no longer employ meter readers. These utilities have been excluded from the customer size and region summaries of this ratio. We added a category for this ratio that shows the percentage of a utility’s customers that have advanced meters installed, and utilities with no meter readers are captured in this ratio.
The first and third quartile and median figures in this final category still reflect only those utilities with at least one meter reader. The weighted mean in this category does include all utilities with or without meter readers. Overall, 27 utilities reported zero meter readers, and all of them were in the “80% or more” class for advanced meter percent.

20. System Load FactorDefinition: The ratio of the system average load, total sales plus losses (MWh) divided by 8,760 (hours per year), to system peak demand (typically a summer or winter peak measured during a particular hour at all delivery points and generator busses on a totalized basis).
System load factor is descriptive of the total system load characteristics. It tells system planners how much the overall system load varies diurnally and seasonally. It is a very broad indicator. It also provides financial planners with information about how to spread fixed costs across energy sales. This metric gives financial planners and rate designers information to support greater unbundling of fixed and variable costs—a goal of competitive rate design.
