Objectives
Review 2012 Rate Analysis and Cost of Service Study
Review financial goals and objectives
Review objectives for general rate filing- Additional rate revenue required- Class revenue requirements- Rate design changes
3
Rate Philosophy
Balance Conflicting Concerns
Financial Objectives
versus
Minimizing Member Impact
4
Steps in the Cost of Service Study Process
Monitor Performance
Coordinate Rate Design with the Line Extension Policy
Define the Customer Revenue Requirement
Define the Rate Class Revenue Requirement
Define the System Revenue Requirement
5
DEFINE SYSTEM REVENUE REQUIREMENT
Cost of Service Study:
6
Define the System Revenue Requirement
Make adjustments to test year financial information for changes that are known, measurable and continuing in nature
Determine margin required to meet long-range financial goals
7
Development of Adjusted Test Year
Test year ending December 31, 2012
Historical test year with adjustments- Revenue adjustments
- Applied existing rates and current COPA to adjusted billing units- Sales adjustments:
- Decline in sales for GS-CBM, LP-CBM, LPT and LPT-CBM
- Removed deferred revenue
- Purchased power adjustments- Applied 2013 wholesale rates
8
Development of Adjusted Test Year
Historical test year with adjustments- Payroll expense reflects current employees and budgeted positions- Benefits expense reflects increased benefit premium for 2013- Existing plant in service
- Includes $6.5 million of electric plant completed and in service but not classified at end of test year
- Future plant additions not included
- Depreciation expense reflects additional $6.5 million of plant and removal of regulatory debit
- Interest expense adjustment- No new borrowing
9
Large Power Contracts:Minimum Billing Demand and Zero Usage
COSS adjusted to reflect contracts that expired at the end of 2012

Primary Concerns in Developing Test Year Data
Proper matching of expenses and billing units
Costs, billing units and resulting unit rates are forward looking
Data can be supported if it is:- Known- Measurable- Continuing in nature
Unit rates reflect “normal” conditions
12
Financial Criteria Required to Define Return
Board Objectives- Recover adjusted test year expenses- Equity objective- Capital credit refund- General funds level- Coverage ratios
Other Factors- Level of plant additions- Cost of debt

What is driving the Revenue RequirementReduced Operating Margins
- Decline in sales- Expiration of minimum bill contracts- Increase in operating expenses- Increased maintenance expenses
Sufficient cash for general funds, financing plant additions and maintain equity and paying capital credits

DEFINE CLASS REVENUE REQUIREMENT
Cost of Service Study:
27
Cost of Service Allocation
Allocates plant investment and operating expenses to the various rate classes
Identifies the return (margin) provided under existing rates
Identifies the required revenue change (increase or decrease) for each rate class
28
A Rate or Customer Class is usually defined by:- Existing rate schedule- Proposed rate schedule
Customers are grouped together if they:- Use energy in similar ways- Cause similar types of costs
Customers Grouped Together
29
Steps in Development of Cost of Service Study
1.• Functionalize Costs
2.• Classify Costs
3.• Develop Allocation Factors
4.• Allocate Investment & Responsibility
30
Classify Costs
Classification of Costs- Fixed (demand)- Variable (energy)- Customer- Direct
Concepts- System is designed to serve customer load- Load is defined in terms of:
- Peak demand- Energy requirements- Number of customers served
31
Allocation Factors
Energy- Sales- Adjust for losses
Customer- Actual Customers- Weighted Customers
Capacity / Demand- Coincident Peak (CP) and Non-Coincident Peak (NCP)- Purchased Power- System
32
Allocation Factors
Consistent methodology and assumptions
Allocation factors updated with current costs and reflect changing relationships between the classes- Meter equipment costs were identified through continuing property
records- Single phase and three phase meter equipment costs were allocated to
appropriate classes
33
Customer Subsidies
Inter-Class Subsidies- Charging one group of customers
more than their share as compared to other member groups
Intra-Class Subsidies - Charging one or more members
within a group more than their share as compared to other members of the group
