D.    Monthly Rate – A monthly demand credit per kW is to be based on the following matrix:

 Annual Hours of Interruption


Notice Minutes









E.      Determination of Measured Load – Billing Demand

 The monthly billing demand shall be the highest average rate at which energy is used during any fifteen consecutive minute period during the below listed hours:



Hours Applicable for Demand Billing - E.P.T.

November through April

6:00 a.m. to 9:00 p.m.

May Through October

10:00 a.m. to 10:00 p.m.


The interruptible billing demand shall be equal to the amount by which the monthly billing demand exceeds the minimum billing demand as specified in the contract.      


F.      Conditions of Service for Member Contract

 1.       The member will upon notification by the Cooperative, reduce his load being supplied by the Cooperative to the contract capacity level specified by the contract

 2.       The Cooperative will endeavor to provide the member with as much advance notice as possible of the interruption of service.  However, the member shall interrupt service within the notice period as contracted.

 3.       Service will be furnished under the Cooperative’s “Rules and Regulations” except as set out herein and/or provisions agreed to by written contract.

 4.       No responsibility of any kind shall attach to the Cooperative for, or on account of, any loss or damage caused by, or resulting from, any interruption or curtailment of this service.

 5.       The Customer shall arrange his wiring so that interruptible service supplied under this rider shall be separately metered and segregated from firm service.

 6.       The Member shall own, operate, and maintain all necessary equipment for receiving electric energy and all telemetering and communications equipment, within the Member’s premises, required for interruptible service.

 7.      A Member’s plant is considered as one or more buildings which are served by a single electrical distribution system, provided and operated by the Member.  When the size of the Member’s load necessitates the delivery of energy to the Member’s plant over more than one circuit, the Cooperative may elect to connect its circuits to different points on the Member’s system.

 8.    The minimum original contract period shall be one year and thereafter until terminated by giving at least six months advance written notice.  The Cooperative may require a contract be executed for a longer initial term when deemed necessary by the size of the load or other conditions.

 9.      Any transformers required in excess of those used for regular firm power shall be owned and maintained by the Member.

10.    The Fuel Adjustment Clause, as specified in the prevailing rate schedule is applicable.


 G.     Calculation of Monthly Bill  

 The monthly bill is calculated on the following basis:

 1.       Sum of the customer charge, plus

 2.       Minimum billing demand in kW multiplied by the firm capacity rate, plus

 3.       Interruptible billing demand in kW multiplied by interruptible rate, plus

 4.       Energy usage in kWh multiplied by the energy rate.


 H.     Number and Duration of Interruptions

1.    There shall be no more than two (2) interruptions during any 24 hour calendar day.  No interruption shall last more than twelve hours.

2.    Interruptions may occur between 6:00 a.m. and 9:00 p.m. EPT during the months of November through April and between 10:00 a.m. and 10:00 p.m. EPT during the months of May through October.

3.    The maximum number of annual hours of interruption shall be in accordance with the customer contracted level of interruptible service.


I.        Charge for Failure to Interrupt

If the member fails to interrupt load as requested by the Cooperative, the Cooperative shall bill the entire billing demand at a rate equal to five (5) times the applicable firm power demand charge for that billing month.  Uninterrupted load is equal to actual load during requested interruption minus firm load.
