There shall be added to or deducted from the net monthly bill $0.00001 per Kilowatt-hour for each $0.00001 increase above or decrease below $0.01692 in the energy supply cost per Kilowatt-hour sales.

The energy supply cost adjustment for each billing month shall be derived from the following formula:

Monthly Adjustment = Fm/Sm – 0.01692

Where:

Fm is total fuel and purchased economic power cost and Sm is total kWh sales (retail sales plus firm municipal sales) for the first two months of the three month period immediately preceding the billing month, all as defined below.

a.Fuel and Purchased Economic Power Cost shall be the sum of the following:

1.The fossil and nuclear fuel consumed in the Company’s generating stations, including the Company’s share of fuel consumed in jointly owned or leased generating stations, as recorded in Accounts 151 and 518,

d.Total Cost of the Purchase is all charges incurred in buying economic power and having such power delivered to the Company’s system.  The total cost includes, but is not limited to capacity or reservation charges, energy charges, adders, and any transmission or wheeling charges associated with the purchase.

e.Total Avoided Variable Cost is all identified and documented variable costs that would have been incurred by the Company had a particular purchase not been made.  Such costs include, but are not limited to, those associated with fuel, start-up, shut-down or any purchases that would have been made in lieu of the purchase made.

f.Under the Mid-Continent Area Power Pool (MAPP) Agreement, Company is required to own, or have available to it under contract, sufficient generating capability to supply its monthly adjusted net system demand while maintaining a reserve capacity obligation equal to 15% of the annual adjusted net system demand.  If Company does not own sufficient generating capacity to meet this obligation, Company will obtain seasonal capacity commitments from other utilities which are party to the Agreement.  If such capacity is not available, Company will obtain needed capacity from an outside party.  The MAPP Agreement also requires Company to meet a daily operating reserve obligation equal to a prorated share of the Pool Total Operating Reserve which is an amount equal to 150% of the capability of the largest generating unit in operation on the interconnected systems of the Pool participants.  Additionally, the MAPP operating reserve requirements states that the spinning reserve portion of the operating reserve shall not be less than 75% of the capability of the largest generating unit in service.  Company’s percentage of Total Operating Reserve is calculated by giving one-third weight to the capability of the Company’s largest unit divided by the sum of capability of each participant’s largest unit and a two-thirds weight to the Company’s Annual System Demand divided by the sum of the Annual System Demands of all participants.  If it is determined that Company cannot, in any hour of the day, meet its load and operating reserve requirements with Company generating resources, owned or under contract, then arrangements will be made to purchase energy from within MAPP to meet such needs.  If sufficient resources are not available from within MAPP, Company will arrange a purchase from a party outside of the Pool.  Purchase will be considered a reliability purchase if required to meet the conditions outlined above.
