Availability:

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.

Rate:

Demand Charge	Summer	Non-Summer
First 750 kw or less billing demand	$14,887.50	$11,910.00
All additional kw	$19.85	$15.88
Energy Charge	Summer	Non-summer
All kwh (cents/kwh)	4.434 cents	3.8 cents

Billing Demand: The maximum 30 minute kw demand measured during the billing month, but not less than 75 per cent 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 thirteen thousand eight hundred (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 two (2) per cent.

Power Factor: The customer will at all times maintain a power factor of not less than ninety (90) per cent lagging. If power factor is less than ninety (90) per cent, the measured kw demand will be multiplied by the ratio of ninety (90) per cent divided by the actual power factor to determine the adjusted measured demand to be used for determination of billing demand. The department 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 industrial customer may elect to reduce electrical consumption when requested to do so by the utility during load shedding periods. 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 is seven hundred fifty (750) kw or above during the summer months. 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 three dollars per month for each kw shed consistently during the utility's system peak periods. The shedding period shall be from June through September.
Metering: The utility will install a recording demand meter to measure the customer's energy load during the periods the utility requests the customer to reduce the load.
Demand reduction: The customer shall receive a credit on the monthly bill beginning in October of each year based on the customer demand shedding ability (not to exceed fifty (50) percent of the normal load prior to shedding).
A customer participating in the load shedding program shall remain in the program for an initial period of one year.

Thermal Storage Rider: The thermal storage rider is available to any customer receiving electric service under the industrial service rate that has installed thermal storage facilities that conform to the utility's load shedding program. Customers interested in this option should contact the department for further information.

Off-Peak Discount: The off-peak discount is available to any customer receiving electric service under the industrial service rate that has an annual load factor of 75% or greater. Customers interested in this option should contact the department for further information.

Interruptible Service Rate: Customers under the Large General Service or the Industrial Service Rate that have at least 500kw of load that can be interrupted by Columbia Water and Light are eligible for the Interruptible Service Rate. Customers on this rate will have a contracted firm demand charge. Interruptible loads are specific areas of a customers service that can be metered and can be entirely removed from service during periods requested by Columbia Water and Light. Arrangements for interruptible service require a signed agreement between the customer and the city. The rate is not available for temporary, standby, breakdown, supplementary or resale service.
