Interruptible rates are available to customers with a demand of 50KW or greater. Under this rate, the customer must agree to have their electric service disconnected when the Utility’s electric system is approaching or in danger of reaching a peak condition. The Utility will give a 15-minute warning before disconnecting the load. Customers must remain in this rate class for a minimum of 12 months.

LOAD FACTOR ADJUSTMENT – If the customer’s load factor for the month (as determined by measurement) is less than 55%, the billing rate will be increased by multiplying the energy and demand rates by 55% and dividing by the average monthly load factor expressed in percent as illustrated in this formula:
If LF<55%, then Adjusted Energy & Demand Billing
Rate = (Billing Rate x 55%)/LF

Notwithstanding the prior calculation, the maximum applicable energy rate shall be $0.095/KWH and demand rate shall be $21.20/KW. Otherwise, the Billing Rate = Billing Rate.

Monthly Surcharge 2023 Bond Issue
$2.450/100 cubic feet

*Surcharge 2023 Bond Issue: In 2022, BMU issued bonds to finance a new water treatment plant and numerous large piping projects. Customer bills will include a monthly surcharge for the financing obligation for the length of the bond issue, which is 30 years.

Each customer will be assigned a Summer Peak Usage Adjustment Level (SPUAL). The SPUAL will be set at an amount equal to 300% of the greater of the Winter Residential City Monthly Average (WRCMA) or the average of the customer’s most recent monthly usage for the months of December through March at the customer’s current residence. The WRCMA will be calculated each year (rounded to the nearest tenth) after the billing cycle is run in March from usage data for the December through March billing periods of the immediately preceding three years. Any customer who does not have water usage history with the utility at the address at which service is requested shall be assigned the WRCMA for purposes of computing their SPUAL.

All water consumed above the assigned SPUAL on bills dated July, August, and September will be billed at the rate of two times the published rate and two times the surcharge rate per 100 cubic feet of water.

Irrigation water rates are determined by multiplying the applicable consumption rate and service charge by a factor of 1.40. The service charge shall be $7.00 per billing cycle for the billing months of November through April for irrigation meters left in place during those months.

Rural water rates are determined by multiplying the applicable consumption rate and service charge by a factor of 1.10.

A $50.00 fee shall be applied when any water meter is reinstalled.
