(A) Applicability. Interruptible service is available to any retail customer capable of meeting the terms and conditions listed below. The retail customer shall enter into a contract with the Indiana Municipal Power Agency (IMPA) and the municipal utilities for an interruptible load of at least 500 kW. The customer shall be billed according to the terms and conditions of the applicable retail service schedule and this section shall be applied as a credit to the bill determined under that schedule.
(B) Terms and conditions of service.
(1) The customer shall enter into a contract with IMPA and the utility for a specific amount of firm load and an additional amount of interruptible load greater than or equal to 500 kW.
(2) IMPA reserves the right to request interruption of the customer's interruptible load at any time at its own discretion subject to the limitations listed below.
(3) The number of interruptions shall not exceed one per day, and the total hours of interruption shall not exceed eight hours per occurrence or 250 hours per year.
(4) IMPA and/or the utility will attempt to provide as much notice as possible of pending interruptions, however, the customer shall interrupt service within 30 minutes if requested to do so.
(5) The customer shall enter into a contract with IMPA and the utility specifying the firm load, the interruptible load and the terms and conditions of service. The initial contract shall be for a term of three years.
(6) Neither IMPA nor the utility are responsible for any loss or damage to the customer's products or equipment as a result of an interruption under this schedule.
(C) Monthly capacity credit.
(1) During months when the customer's interruptible load is interrupted during the hour of the utility's billing demand, IMPA will credit to the utility and the utility will credit to the customer an amount equal to $2.50 per kW times the interruptile billing demand. The interruptible billing demand is the four hour average of the customer's 60 minute demands prior to the hour of interruption minus the greater of the customer's contracted firm load or the customer's actual metered load during the hour of the utility's billing demand.
(2) During months when there is no interruption during the hour of the utility's billing demand, IMPA will credit to the utility and the utility will credit to the customer an amount equal to $2.50 per kW times the customer's 60 minute demand minus the customer's contracted firm load during the hour of the utility's billing demand.
(D) Failure to fully interrupt.
(1) During any month, if the customer fails to reduce its total load to no more than its contracted firm load plus 10% of its contracted interruptible load when requested to do so, the customer will incur a penalty for such failure. Such penalty will be in addition to the regular charges payable under the utility's applicable rate schedule.
(2) The penalty will be an additional fee per kW applicable to the customer's metered kW during the hour of the utility's billing demand less the sum of the customer's contracted firm load and 10% of the customer's contracted interruptible load. During any 12 consecutive months, this additional fee will be $2.50 per kW for the first month, $5.00 per kW for the second month and $15 per kW for all subsequent months of such failure to interrupt. This additional fee will be billed by IMPA to the utility and by the utility to the customer.
(E) Request for/acknowledgment of interruption. Requests for interruption and permission to terminate interruption will be made, at IMPA's option, by telephone or by electronic signal at the customer's premises. Specific procedures for requests for interruptions and acknowledgment of such requests shall be included in the customer's contract with IMPA and the utility.
(F) Metering. The customer will provide space, facilities and cost reimbursement to the utility for a utility-provided recording demand meter to measure the customer's 60 minute integrated demand. IMPA and the utility shall have the right to obtain meter readings and inspect and test meters at all times.
(G) Other. All other provisions of the utility's applicable retail rate schedule apply to this section.
