ORDINANCE NO. 4483
AN ORDINANCE TO AMEND CHAPTER 28, UTILITIES,
DIVISION 1, ELECTRIC OF THE MUNICIPAL CODE OF THE
CITY OF AMES, IOWA, BY ENACTING A NEW SECTION
28.106 AND AMENDING SECTION 28.108 FOR THE PURPOSE
OF COMMERCIAL ELECTRIC VEHICLE CHARGING RATE
AND INDUSTRIAL TIME-OF-USE ELECTRIC RATES AND
CHARGES; REPEALING ANY AND ALL ORDINANCES OR
PARTS OF ORDINANCES IN CONFLICT TO THE EXTENT
OF SUCH CONFLICT; AND ESTABLISHING AN EFFECTIVE
DATE.
BE IT ENACTED
, by the City Council for the City of Ames, Iowa, that:
Section One. The Municipal Code of the City of Ames, Iowa shall be and the same is hereby
amended by enacting a new Section 28.106 and amending section 28.108 for the purpose of commercial
electric vehicle charging time-of-day rate and industrial time-of-use electric rates and charges as follows:
“…
Sec. 28.105. COMMERCIAL RATE.
…
Sec. 28.106. COMMERCIAL ELECTRIC VEHICLE CHARGING RATE.
Availability.
(1)The “Commercial Electric Vehicle Charging Rate” is solely for the
charging of electric vehicles. The rate shall be voluntary for any non-residential customer whose
consumption in any billing period exceeds 10,000 kWh, or whose metered demand at any time exceeds 55
kVA. Any customer who elects the Commercial Electric Vehicle Charging Rate shall not switch rates
more than once in a period of twelve (12) months. Any customer on Commercial Electric Vehicle
Charging Rate who has a metered demand of less than 55 kVA, or a consumption of less than 10,000
kWh, for twelve (12) consecutive months, shall be changed to the Small Commercial Rate.
Intent:
(2)Electric Services is a summer peaking electric utility, and as such, the cost to
deliver electricity is generally most expensive during hours of greatest demand. The utility benefits when
large electric users reduce their demand during these times. A time-of-day rate is a pricing strategy
whereby Electric Services may vary the price of electricity depending on the time-of-day it is delivered to
the customer. Energy pricing can encourage the customer to use electricity during times of low demand
and discourage use during the peak times of the day. Time-of-day pricing allows Electric Services to better
control costs and mitigate any negative system impacts related to times of peak demand. Additionally,
offering off-peak rates encourages broader adoption of electric vehicles by allowing low-cost, off-peak
energy for customer vehicle charging.
Definitions:

Premium Hours
(a): Monday through Friday between the hours of 9:00 am and
9:00 pm, excluding federally observed Holidays:
Economy Hours
(b): All remaining hours
Billing Demand
(c) :
The “billing demand” shall be the greater of:
⦁
The peak fifteen (15) minute demand measured during the premium hours
of the current monthly billing period;
⦁
Thirty percent (30%) of the peak fifteen (15) minute demand measured
during the economy hours of the current monthly billing period;
⦁
Seventy-five percent (75%) of the greatest billing demand for the summer
period during the prior eleven (11) billing periods;
⦁
Sixty percent (60%) of the greatest billing demand during the prior eleven
1
(11) billing periods;
⦁
40 kVA.
Rate Per Billing Period:
(4)For each monthly billing period, a customer
participating in the Commercial Electric Vehicle Charging Rate shall be
charged:
(a)the Service Charge of two hundred fifty dollars ($250.00).
(b)the Demand Charge and the Energy Charge for the billing period as follows:
(i)for bills mailed on or between July 1 and October 31 (summer period),
a customer shall be charged a demand charge of $10.71 per kVA of billing demand
(ii) for bills mailed on or between November 1 and June 30 (winter
period), a customer shall be charged a demand charge of $8.01 per kVA of billing
demand
(iii) a customer shall be charged an energy charge of:
$0.12 per kWh during “premium” hours
$0.04 per kWh during “economy” hours
(c)all charges above shall also be subject to the applicable Energy Rate
Adjustment (ERA) per Sec. 28.102.
Sec. 28.107. INDUSTRIAL RATE.
…
Sec. 28.108. INDUSTRIAL TIME-OF-USE ELECTRIC RATE AND CHARGES.
Availability:
(1)The Industrial Time-of-Use Electric Rate shall be voluntary for any
customer whose metered demand at any time exceeds 2,500 kVA. Service under this rate schedule is
billed on a Time-of-Use basis as provided under these rules. The Industrial Time-of-Use Electric Rate is
an alternative to Section 28.107 (1) Availability, at the customer’s discretion. Customers opting for
inclusion on Industrial Time-of-Use Electric Rate are required to remain on the rate for a period no less
than twelve (12) consecutive calendar months.
Intent:
(2)Electric Services is a summer peaking electric utility, and as such, the cost to
deliver electricity is generally most expensive and detrimental to generation and distribution systems
during hours of greatest demand. The utility benefits when large electric users are encouraged to reduce
their demand during these times. A Time-of-Use Rate is a pricing strategy whereby Electric Services may
vary the price of electricity depending on the time-of-day it is delivered to the customer. Prices encourage
the customer to use electricity during times of low demand and discourage use during the peak times of
the day. Time-of-Use (TOU) pricing allows Electric Services to better control costs and mitigate any
negative system impacts related to times of peak demand.
Definitions:

hour day used for establishing a pricing strategy aimed at reducing the overall demand for electricity.

Interruptible Option -Availability:
(5) Service under this rate shall be available for customers
with monthly demands of 2,500 kilovolt-amps (kVA) or greater. Service under this rate schedule is
interruptible and customers must agree to interrupt electric service as provided under these interruptible
rate rules.
⦁
A minimum interruptible load of 500 kVA is required to qualify for interruptible
service.
⦁
Electric Services shall verify Customer compliance with this requirement through
the use of customer-specific interval demand meters.
⦁
Any customer eligible for the interruptible rate who wishes to participate shall
establish an interrupt amount based on their previous summer’s average peak kVA demand (the average
billed demand of bills mailed in July, August, September, and October).
⦁
The interrupt amount shall be agreed upon by the customer and City of Ames
Electric Services.
⦁
Load interruptions are only requested during the months of June, July, August, and
September.
⦁
Customer shall be given a minimum of 4 hours notification on the day of
interruption.
⦁
Customer must interrupt at the agreed upon elected amount between the hours of
3:00 pm and 8:00 pm, or shorter duration as determined by the City.
⦁
Customer shall not be interrupted on more than three consecutive days, and no
more than five (5) times in a billing period.
⦁
Customer credits for participating in the interruptible rate option shall be applied to
the customer’s bills mailed out in July, August, September, and October. Customer participation credits
are applied irrespective of a request to interrupt.
⦁
Any customer on this rate will be given a credit of $2.60 per elected kVA as a
participation incentive on bills mailed out in July, August, September, and October.
⦁
In addition to the participation credit, a customer will be given a compliance credit
of $2.60 per elected kVA for successfully lowering its demand by at least the amount of the elected
interruptible demand. The amount of participation credit applied to the billing demand is based upon the
largest interruption response of the billing period. Failure to curtail the full elected amount will result in
no compliance credit.
3
⦁
In the event a participating customer is unable to interrupt load, a non-compliance
penalty will be charged to the billing period’s demand in the amount of $12.00 per kVA for each kVA
short of the elected amount. The amount of noncompliance charge applied to the billing demand is based
upon the largest noncompliance of the billing period. The compliance credit is equal to the elected
participation minus the amount of noncompliance. Such charge shall be in addition to any charges
otherwise payable to City of Ames Electric Services for electric service under this rate schedule. The
payment of this noncompliance penalty shall not be considered a substitute for any other remedy available
to Electric Services including, but not limited to, reduction of service.
