AN ORDINANCE TO AMEND THE MUNICIPAL CODE
OF THE CITY OF AMES, IOWA BY REPEALING
SECTIONS 36-8002, 36-8003 and 36-8004
THEREOF AND ENACTING NEW SECTIONS
36-8002 , 36-8003 and 36-8004 FOR THE
PURPOSE OF REVISING THE RATES OF THE
MUNICIPAL ELECTRIC UTILITY; REPEALING
ALL ORDINANCES OR PARTS OF ORDINANCES
IN CONFLICT HEREWITH TO THE EXTENT OF
SUCH CONFLICT IF ANY ; AND ESTABLISHING
AN EFFECTIVE DATE
BE IT ENACTED, by the City Council for the City of
Ames , Iowa:
Section One . The Municipal Code of the City of
Ames, Iowa shall be and is hereby amended by repealing sec-
tions 36-8002 , 36-8003 and 36-8004 thereof as said sections
have existed heretofore.
Section Two . The Municipal Code of the City of
Ames , Iowa is amended further by enacting new sections
36-8002 , 36-8003 and 36-8004 , said new sections to read as
follows :
"Sec. 36-8002 . Rates Established
The rates at which charges will be made
for electric energy and service rendered
to consumers by the electric utility of
the City are established by Sections
36-8003 and 36-8004 hereof. The net
monthly billing based on said rates will
be increased or decreased by an amount
corresponding to the increase or decrease
in the average cost to the City for power
plant fuel in the preceding month. The
incremental charge will be computed by
multiplying the number of kilowatt hours
used by a customer by . 016 times the
difference between the base fuel cost and
the average fuel cost of the preceding
month. The base fuel cost is $1 . 2375 per
million BTU. The average fuel cost shall
be determined by dividing the total cost
of fuel burned in the city-owned generat-
ing facilities in the preceding month by
the total heating value of the fuel burn-
ed in the same period in BTU (British
Thermal Units) times one million. In the
event all or any part of the energy sup-
plied is generated in facilities not
owned by the City and obtained by the
City through power purchases or plant
participartion agreements , the fuel price
adjustment shall be modified to account
for the fuel price adjustment affecting
the generation cost of non-owned generat-
ing facilities .

factor adjustment may be made, at
the option of the city, when the

times 1 . 5 times (Current Month
Measured Demand)
(7) Service facilities : The city shall
furnish as a standard installation
facilities adequate to supply ser-
vice at a single point of delivery
to a normal load equal to the maxi-

include , where necessary, facili-
ties for one standard transformation

rental payable by the customer
shall be that portion of the
total rental which is reasonably
assignable to the customer.
(9) Multiple metering: Where two or
more demand metering installations
are provided, the maximum 30-
minute demand shall be determined
by adding together the separate
demands at each metering installa-
tion. However, primary metering
may be installed to measure the
total demand at one point , if
feasible. Where two or more
watthour metering installations
are provided, the total Kwh used
for billing purposes shall be
determined by adding together the
Kwh metered at each installation.
However, the maximum demand and
Kwh supplied at two or more pre-
mises will not be combined for
billing purposes hereunder.
(10) Primary service: Customers who
take service at primary voltage
shall be granted discounts as
follows :
-7-
(a) 1-1/2% of the demand and
energy charge where meter-
ing is on the high voltage
side of the city-owned
transformers.
(b) 5% of the demand charge and
1-1/2% of the energy charge
where metering is on the
high voltage side of customer-
owned transformers.
(11) Conditions :
(a) General condition (a) as set
forth in section 36-8005 applies .
(b) The following specific con-
ditions also apply:
(1) The customer ' s total
usage on a single premise
shall determine whether
the customer qualifies
for service under this
rate structure. In no
event will the customer
be billed on both the
general power and large
power rates. A premise
:is defined as the main
building of a commercial
or industrial establish-
ment, and shall include
the outlying or adjacent
buildings used by -the
same provided the use of
service in the outlying
buildings is supplemental
and similar to the service
used in the main building.
(2) Before the space heating
rider is put into effect,
the heating system shall
be inspected and approved
by the City of Ames
Electrical Utility.
(3) Fluctuating loads . If
use of energy is inter-
mittent or subject to
violent fluctuation, the
city may base the metered
demand upon a 10-minute
demand period, or add to
the 30-minute measured
demand an amount equal
to 65% of the rated
capacity in Kw of appa-
ratus which causes such
fluctuations. "
