GENERAL CONDITIONS FOR ELECTRIC RATES. The following general conditions are applicable to the following as indicated in each rate schedule: (1) Service shall be provided subject to Ames Municipal Electric System rules, regulations, and the tariff filed with the Iowa State Commerce Commission. (2) The schedule will be applied to each meter and point of delivery and in no event will meter readings be combined. (3) Where a residence and a business are combined on one premises, service for the combined use will be considered residential only if the predominant use is for residential purposes. If the use is predominantly for business purposes, the customer is required to take all service under the applicable General Power or Large Power rate. (4) The standard approved type of electric water heater shall have a single 120 volt heating element no larger than 1500 watts or shall have multiple thermostatically controlled noninductive 240-volt heating elements of not more than 5000 watts per element with such multiple elements connected interlocking so that only one element may operate at a time. (5) The utility may assess an excess facilities charge when necessary to meet costs of an unusual installation. Sec. 28.2. ENERGY COST ADJUSTMENT. The net monthly billing based on rates will be increased or decreased by the an amount corresponding to the increase or decrease in the average cost to the Ames Municipal Electric System for power plant fuel in the pre- ceding month. The incremental charge will be computed by multiplying the number of kilowatt-hours used by the customer times the difference between the base fuel cost and the average fuel cost of the preceding month. The base fuel cost is $0.0272 per kilowatt-hour. The average fuel cost shall be determined by multiplying the unit fuel cost in the previous month times the quantity of fuel used in the twelve (12)-month period prior to the previous month divided by the actual kilowatt-hour sales during the same period. 2 In the event of energy purchases and/or sales with facilities not owned by the Ames Municipal Electric System through interchange agreements, plant participation agreements, or steam sales by the Ames Municipal Electric System, the energy cost adjustment shall be modified to account for said purchases and/or sales. Energy cost revenues shall be reconciled with actual energy costs on an annual basis. Sec. 28.3. RESIDENTIAL ELECTRIC RATES. (1) Availability: Electrical energy and service shall be available at the "Residential Rate" for all single-phase domestic uses in separately metered, dwelling units that are intended for occupancy by a single family as defined by the Ames Zoning Ordinance, as distin- guished from group domiciles such as rooming houses, fraternity or sorority houses, supervised group homes, and residential care facilities of various kinds. (2) Rate per billing period. For each monthly billing period a residen- tial rate customer: (a) shall be charged three dollars and fifty cents ($3.50) as a customer service charge, and (b) in addition, shall be charged for energy consumption during the billing period as follows: (i) for bills mailed on or between July 1 and October 31 (summer period): $0.082 per Kwh for the first 400 Kwhs $0.078 per Kwh for the next 600 Kwhs $0.072 per Kwh for all Kwhs over 1000 Kwhs, or (ii) for bills mailed on or between November 1 and June 30 (winter period): $0.073 per Kwh for the first 400 Kwhs $0.062 per Kwh for the next 600 Kwhs $0.059 per Kwh for all Kwhs over 1000 Kwhs, and (c) shall be charged any applicable energy cost adjustment per Sec. 28.2. (3) Minimum bill: The minimum charge per billing period shall be three dollars and fifty cents ($3.50) .

(1) Availability: Electrical energy and service shall be available at the "General Power Rate" to all customers except those that qualify for another rate schedule, for all single-phase or three-phase, single- metered usage, where the metered demand does not exceed 50 Kw. (2) Rate per billing period: For each monthly billing period a general power rate customer: (a) shall be charged five dollars ($5.00) as the customer service charge; and, (b) in addition, shall be charged for energy consumption during the billing period as follows: (i) for bills mailed on or between July 1 and October 31 (summer period): $0.087 per Kwh for the first 2000 Kwhs $0.075 per Kwh for the next 5000 Kwhs $0.073 per Kwh for all Kwhs over 7000 Kwhs. For customers with demand meters and who have a consump- tion over 7,000 Kwh in a month, the above rate will apply to the first 400 hours use of metered demand. For Kwhs use over 400 hours use of metered demand, the additional Kwhs shall be charged at $.060 per Kwh. (ii) for bills mailed on or between November 1 and June 30 (winter period): $0.069 per Kwh for the first 2000 Kwhs $0.058 per Kwh for the next 5000 Kwhs $0.056 per Kwh for all Kwhs over 7000 Kwhs. For customers with demand meters and who have a consump- tion over 7,000 Kwh in a month, the above rate will apply to the first 400 hours use of metered demand. For Kwhs use over 400 hours use of metered demand, the additional Kwhs shall be charged at $.050 per Kwh. (c) shall be charged any applicable energy cost adjustment per Sec. 28.2. (3) Minimum bill: The minimum charge per billing period shall be five dollars 5.00). 4 (4) Conditions: The general power rate shall be subject to: (a) the general conditions of section 28.1 (1), (2), (3) and (5); and, (b) the following specific conditions: (i) Unless three-phase service is determined by the Ames Municipal Electric System to be economically available, motors up to and including 5 hp shall be single-phase. Motors above 5 hp shall be three-phase. Three-phase service will normally be 120/208 volt, 4 wire.

(ii) Fluctuating loads. Loads requiring excess transformer capacity because of large momentary current require- ments, or to provide close voltage regulation, shall be subject to an additional charge of $0.30 per rated Kva of capacity above normal capacity requirement for the diversified demand. The Kva subject to an additional charge will be adjusted no more than once a year. No charge shall apply if the customer furnishes the trans- formers. (iii) Should the electrical energy furnished under this schedule for any reason be metered on the primary side of the service transformers, the energy metered shall be reduced by 1-1/2 per cent before calculating the energy charge. Sec. 28.5. LARGE POWER RATE. (1) Availability. The Large Power rate shall be optional for any non-residential customer whose consumption in any billing period exceeds 10,000 Kwh. The Large Power rate shall be mandatory for any non-residential customer whose metered demand at any time exceeds 50 Kw. If at any time, a non-residential customer's metered demand exceeds 50 Kw, all consumption for the billing period in which that occurs, and for the next succeeding eleven billing periods, shall be charged at the Large Power rate. Any customer for whom the Large Power Rate became mandatory, who subsequently has a metered demand of less than 50 Kw for 12 consecutive months, will again become an optional Large Power customer with a choice between General Power and Large Power rates.
