Demand Electric Service Rate Minimum Bill: Maximum billing demand during previous twelve months times 3.0%of the demand charge, or the actual demand multiplied by the demand charge, whichever is greater plus$1.00 per kVA per month of excess transformer capacity requested by customer. Determination of Billing Demand:The billing demand shall be the highest measured demand (corrected for power factor if required) during any fifteen (15) minute period occurring in the current billing period. But in no month shall the billing demand be greater than the value in kW determined by dividing the kWh sales for the billing month by 75 hours per month. This billing adjustment applies only if the customer's peak demand DOES NOT occur between the hours of 3:00 p.m. and 10:00 p.m. Fluctuating Loads: Customers operating equipment having a highly fluctuating or large instantaneous demand,such as welders and X-ray machines, shall be required to pay all non-betterment costs of isolating the load from the balance of Elk River Municipal Utilities' system so that the load will not unduly interfere with service on Elk River Municipal Utilities' lines. In addition,Customers who fail to provide adequate corrective equipment shall be required to own and maintain their own transformers. No motor larger than ten (10) HP (or 7.355 kW)will be allowed to be across-the-line started without notification and written authorization from Elk River Municipal Utilities. Power Factor Adjustment: For loads of 50 kW or more, or at the option of Elk River Municipal Utilities for loads of less than 50 kW, power factor adjustments may be made in the billing demand,when the power factor, as determined by test, at the time of the Customer's maximum use is less than 95%. If the power factor, as measured by Elk River Municipal Utilities' electric department, is lower than 95%,the monthly demand charge may be multiplied by the ratio 95%divided by the measured power factor, or at Elk River Municipal Utilities option,the power factor may be corrected at the Customer's expense.
