ELECTRIC RATE REVIEW
SUMMARY
Based on information which was developed in the July 1986 Cost of Service
Study (Test Year 1986/1987), a Rate Review has been performed for the City of
Petersburg. The purposes of this review were:
1. To determine how well the revenues obtained from each consumer class
under the current level rate structure match the costs associated with
providing electric service to each consumer class.
2. To design a block rate structure for each consumer class which would:
a. Equitably recover sufficient revenues from each consumer class to
meet the cost and the margin requirements associated with each
class.
b. Offer a cost of power incentive in each consumer class for
increased individual use and consumption of electric power.
The rationale for offering an incentive for increased consumption of electric
power is based on the availability of a firm, long term source of
hydroelectric power under the City of Petersburg's 45 year contract with Tyee.
COST OF SERVICE ANALYSIS
The Municipal Power and Light Department costs associated with providing
electric service for the City of Petersburg were functionalized, classified,
and allocated to each of five consumer classes in the July 1986 Cost of
Service Study. The consumer classes are residential, small commercial, large
commercial, boat harbor, and street lighting.
The twelve month period beginning 7/1/86 and ending 6/30/87 was selected as
the test year. Expense, plant and consumption baseline data for the test year
were derived from financial statements, other cost related studies, budgets
and projections which have recently been developed by the staff and management
of the City's electric department.
Electric plant account balances were developed by calculating a 12-month
average balance for the period 7/1/86 through 6/30/87. Projected operating
expenses were functionalized per a two year (1984-85) composite percentage of
COP's general ledger operating expense account balances.
Purchased power expense was developed by applying the City's budgeted
wholesale power costs to expected test year consumption for the 12-month
period ending 6/30/87. Monthly purchased power costs per each class were
allocated on the basis of estimated monthly KWH consumption.
2249S 1
For review against revenues, two types of cost tables were developed for each consumer class. One cost table shows $/consumer/month at several KWH usage levels, while a second cost table shows $/KWH for the same KWH usage levels. The data from these cost tables was then plotted for graphic comparison with revenues from current rates and with revenues from proposed rates.
REVENUE ANALYSIS: CURRENT RATES
The current COP retail electric structure was applied to the five consumer
classes as follows:
Residential $12 per month service charge,
plus $0.091 per KWH used over 50 KWH
Small Commercial $12 per month service charge,
plus $0.091 per KWH used over 50 KWH
Large Commercial $3.85 per month per KW of peak demand,
plus $0.088 per KWH used
Boat Harbor same as residential and small commercial
Street Lighting $9.00 per month per 100 watts
Revenue tables for the test year at current retail rates were developed for
each consumer class to show $/consumer/month and $/KWH per month at several
KWH usage levels. Data from these tables was then plotted along with the cost
curve data to show graphically how revenues at current rates would match test
year costs.
In addition, revenues at current rates for the projected test year consumption
were calculated for each class and both dollar and percentage excesses or
deficiencies from required funds (costs) were determined. This data is
presented in the Cost of Service Summary - Current Rate - Table in Section II.
REVENUE ANAYSIS: PROPOSED RATES
During a two day rate design workshop session involving COP Municipal Power
and Light Department staff, COP Utility Board and City Council members, and
POWER Engineers, several declining block rate schedules were formulated, and
projected revenues were calculated using POWER Engineers revenue test computer
program. The following declining block rate schedule was identified as
meeting the objectives of equability of cost recovery amongst consumer classes
and incentive for increased consumption:
Residential $8.00 per month service charge
$0.095 per KWH for 0-500 KWH
$0.091 per KWH for 501-1000 KWH
$0.065 per KWH for all over 1000 KWH
Smal] Commercial $8.00 per month service charge
$0.098 per KWH for 0-1500 KWH
$0.096 per KWH for 1501-3000 KWH
$0.065 per KWH for all over 3000 KWH
2249S 2
Large Commercial $25 per month service charge
$3.85 per month per KW at peak demand
$0.089 per KWH for 0-30,000 KWH
$0.087 per KWH for 30,000-60,000 KWH
$0.065 per KWH for all over 60,000 KWH
Boat Harbor $8.00 per month service charge
$0.098 per KWH for 0-500 KWH
$0.096 per KWH for 500-1000 KWH
$0.065 per KWH for all over 1000 KWH
Street Lighting $9.00 per month per 100 watts
Revenue tables for the test year at these proposed rates were developed for
each consumer class to show $/consumer/month and $/KWH per month at several
KWH usage levels. Data from these tables was then plotted along with the cost
curve data to show graphically how revenues at the proposed rates would match
test year costs.
In addition, revenues at these proposed rates for the projected test year
consumption were calculated for each class and both dollar and percentage
excesses or deficiencies required funds (costs) were determined. This data is
presented in the Cost of Service Summary - Projected COP 1 Rate - Table in
Section II.
DATA PRESENTATION
The tables and graphs included in this rate review are presented in the
following format:
Section II contains revenue test summary tables for current and proposed
rate schedules. It also contains cost of service summary tables for
current and proposed rates, plus a table showing the allocation of
operating expenses by consumer class.
Sections III through VII are by consumer class. Each consumer class
section contains cost and revenue tables and graphs organized in the
following manner:

CONCLUSION
Test year costs will be recovered by either the current rate schedule or the
proposed, declining block rate schedule. The declining block rate schedule
may be advantageous in that it should allow the City of Petersburg to
experience the positive effects of demand elasticity. That is, the lower
rates for higher usage should be incentive for more consumption of
electricity. Present consumers may expand usage and some new users may be
attracted. This will allow fixed costs to be spread over more units of
consumption which will enhance the performance of the declining block rate
schedule as a revenue recovery vehicle.

SECTION VII
STREET LIGHT DATA
POWER Fnaineers inenrnarat. ad
STREET LIGHTS
Street lights are not metered and are billed according to wattage. They are,
thus, best discussed in terms of $/watt. Cost and revenue analyses based on
$/consumer/month and $/KWH/month are not as meaningful for the street lighting
class as they are for other classes. Therefore, cost curve and revenue curve
tables and graphs have not been included for this class. However, the costs
and revenues associated with street lighting were determined and are included
in the rate review Summary tables in Section II. This information is
summarized below.
Installed street light wattage: 72,450
Estimated annual hours use 4188
Estimated annual street light usage (KWH): 304,000
Estimated average annual load factor: 0.48
Test year costs allocated to street lighting: $44,632
Cost per month per 100 watts: $5.13
Current billing rate (implemented 7/86): $9.00 per 100 watt
Proposed rate schedule for street lighting: Retain current rate
Test year street light revenues, at current and proposed rates
Sales revenue $78 ,082
Other revenue 8,540 Total operating revenue $86,622
