All large commercial customers that exceed seven hundred fifty (750) kW demand during June, July, August, or September will automatically be placed on the Industrial Service Rate. Not available for temporary, standby, breakdown, supplementary, or resale service.
|Monthly Customer Charge||$161.45||$161.45|
|First 750 kW or less billing demand||$16,705.93||$13,316.74|
|All additional kW||$22.27||$17.76|
|All kWh||5.09 cents||4.35 cents|
Billing Demand: The maximum 30 minute kW demand measured during the billing month, but not less than 75% of the maximum billing demand during the billing months of June, July, August and September of the preceding 11 month billing period.
In Lieu Of Gross Receipts Tax and Sales Tax: In addition to the charge based on monthly rates as computed above, the total monthly charge for service shall include applicable sales taxes and an in lieu of gross receipts tax payment equal to 7.5268% of the monthly rate charge. Sales taxes shall be applied to the total of the monthly rate charge and the in lieu of gross receipts tax payment.
Primary Service: When the customer owns and maintains all equipment, except metering equipment, necessary to take service at 13,800 volts or higher, total rate charges will be reduced by ten cents ($0.10) times the highest thirty-minute kW demand during the billing cycle.
Primary Metering: If, at the option of the department, service is metered at primary voltage, the measured demand and kwh will each be decreased by 2%.
Power Factor: The customer will at all times maintain a power factor of not less than 90% lagging. If power factor is less than 90%, the measured kW demand will be multiplied by the ratio of 90% divided by the actual power factor to determine the adjusted measured demand to be used for determination of billing demand. Columbia Water & Light may, at its option, use for adjustment the power factor determined: 1.) By test during periods of maximum demand; or 2.) By measurement of the average monthly power factor.
Load Shedding Program: Any large general service customer may elect to reduce electrical consumption when requested to do so by the utility during load shedding periods. Large general service customers who wish to participate in the utility’s load shedding program shall inform the utility in writing no later than April 15 of each year. The application of this service will be limited to customer’s whose billing demand from one account is 750 kw and above during the summer months of July and August and whose billing demand from multiple accounts is one thousand (1,000) kw and above during the summer months of July and August. More specific terms of the load shedding program shall be defined in a separate agreement between the customer and the city.
Monthly rate: Credit for demand shedding will be computed as follows:
- Performance rate. If the electric utility requests customer to shed load, the performance rate shall be calculated at $3.00 per month for each kW shed on average for the load shedding periods during the months of June through September. If there is no load shedding event in a given year, the credit shall be reduced to 50% of the performance rate and shall remain at that level until the customer sheds demand as part of this program in any subsequent year or until the customer’s participation in the program ends, whichever occurs first.
Metering: The utility will install all recording demand meters to measure the customer’s energy load during the periods the utility requests the customer to reduce the load. The utility shall pay for the first meter installed. Customer shall be responsible for all costs associated with all other recording demand meters installed by the utility for the customer’s participation in the program. Customer, at customer’s expense, shall also be responsible for installing and maintaining a connection to each meter for use by the utility.
A customer participating in the load shedding program shall remain in the program for an initial period of one year.
Energy Storage Rider:
- Available: The energy storage rider is available to any customer receiving electric service under the industrial service rate that has installed energy storage facilities approved by the utility as being capable of sustaining at least five hundred (500) kw in equivalent energy capacity for continued load reduction for a minimum of four (4) hours.
- Energy charge: Energy supplied for the period beginning 12:00 midnight and ending at 6:00 a.m. shall be charged at the rate of 3.76 cents per kwh during the summer months and 3.37 cents per kwh during the non-summer months. Energy charged at this rate will be subject to the fuel adjustment allowance in section 27-118.
- Demand charge: As set forth in separate agreement between the utility and customer, for a period of twenty (20) hours each day the monthly measured demand will be excluded for the purpose of the billing of demand as set forth in subsection (f) while under this rider. Measured demand period will exclude Saturday and Sunday of each week.
- Billing demand: The maximum thirty-minute kw demand measured during the billing month, but not less than seventy-five (75) percent of the maximum billing demand during the billing months of June, July, August and September of the preceding eleven (11) months. If there has been a significant change in operation from the previous year, the director may reduce a customer’s ratchet amount to fifty (50) percent until a new maximum billing demand is set during the forthcoming June, July, August and September.
- Metering: The utility will install all recording demand meters necessary to measure the demand period. The customer shall pay a non-refundable fee to cover the actual costs for the metering required for the energy storage rider.
- Load shedding program: The load shedding program does not apply to the energy storage rider.
- Contract: Customers wishing to receive service on the energy storage rider must first enter into an agreement with the city that includes provisions concerning: emergency use of the system; a description of the energy storage system; listed hours in which demand charges are excluded; and length of the term of the contract.
- In lieu of gross receipts tax payments and sales tax: In addition to the charge based on the rates set forth in this subsection, the total monthly charge for service shall include applicable sales taxes and an in lieu of gross receipts tax payment equal to 7.5268 percent of the monthly rate charge.

Qualifying customers must notify the water and light department, in writing, that the customer wants to receive the off-peak discount.
- Energy charge: Energy supplied for the period beginning 12:00 midnight and ending at 6 a.m. shall be charged at the rate of 3.86 cents per kwh during the summer months and 3.46 cents per kwh during the non-summer months.

At the time of interruption the meter reading for that period should register zero. If the customer is unable to interrupt the total load at the utility’s request, a charge of $36.40 per kilowatt will be charged on the kilowatt load registered on the meter during that period. If the customer continues to violate the terms of the interruptible agreement, the customer will be removed from the interruptible rate and put on a rate based on the customer’s loads during the previous summer period. The customer will not be allowed to reapply for the interruptible rate for one year. Customers with auxiliary power connected to the interruptible load will be allowed up to one percent of the interruptible kilowatt load on the meter before the charge for the auxiliary load will be billed at $36.40 per kilowatt on a monthly basis during the interruptible period.
Monthly rate charge:The monthly rate per kilowatt hour shall be as follows, subject to fuel adjustments as provided in section 27-118:
Summer Non-Summer Customer charge (per month) $60.00 $60.00 Demand charge (per kilowatt) $10.08 $8.07 Energy charge (per kilowatt hour) $0.0469 $0.0438
