Standard Commercial / Industrial Rates

Large Commercial and Multi-Family Service (4.8kV)

The rates shown below are the total costs as shown on your bill. To view the individual Adjustment Factors, please go to Commercial Adjustment Billing Factors.

To view the individual components that make up this rate, please go to Rate Ordinance.

Winter rates are effective October through May, and summer rates are effective June through September.  If your billing read dates cross over a price change, your costs will be adjusted based on the number of billing days used in each month.

These rates are for commercial services delivered from the Department's 4.8kV system and with facility demands greater than 30 kW.

Large Commercial and Multi-Family Service (4.8kV) Time-of-Use Rate A-2B

Adjustment Billing Factors: *Adjusted in January, April, July and October

In addition to the charges above, reactive charges will be added to the bill based on the meter configuration. If the meter cannot measure kVarhs then use Table 1 below. If the meter can measure kVarhs, then use Tables 2 and 3 below.

Table 1 – Reactive Charges Based on kWh (Meter does not measure kVarh)

Table 2 – Reactive Charges Based on kVarh (Meter measures kVarh) 
Summer (June through September)

Table 3 – Reactive Charges Based on kVarh (Meter measures kVarh) 
Winter (October through May)

General Conditions:  
a.    Reactive Energy Charge  
       The Reactive Energy Charge shall be based on the lagging kilovar-hours (kvarh) recorded during each Rating Period, dependent upon the High Peak Period Power Factor. If reactive energy is unknown or unmetered, then the Reactive Energy Charge shall be replaced by additional kilowatt-hour charges. 

b.    Maximum Demand 
       The Maximum Demand is the average kilowatt load to the nearest one-tenth kilowatt during the 15-minute period of greatest use during a billing period, as recorded by the Department's meter. Demand is another term for power and is expressed in units of kilowatt.

In cases where demand is intermittent or subject to severe fluctuations, the Department may establish the Maximum Demand on the basis of measurement over a shorter interval of time or the kilowatt-amperes of installed transformer capacity required to meet the customer's load.

c.    Demand Charge  
       The Demand Charge shall be based on the Maximum Demand recorded at any time during the billing month.

d.    Facilities Charge  
       The Facilities Charge shall be based on the highest demand recorded in the last 12 months, but not less than 30 kW.

e.    Load Factor 
       Load factor is a ratio between average usage and peak usage over a given period. A high load factor has a relative low kW demand with higher kWh usage, which leads to an overall lower cost per kWh. A low load factor has a relatively high kW demand with lower kWh usage, which leads to an overall higher cost per kWh. Commercial customers may be able to save money if they can improve their load factor. 

f.     Electric Vehicle Discount 
       Owners of licensed passenger or commercial electric vehicles shall be entitled to a discount on the block of energy designated by the Department as necessary for basic vehicle charging. Proof of vehicle registration and charging location is required. 

g.     Metering 
        Metering of energy and demand shall normally be provided by the Department at the primary side of the transformer, or at the Department’s option, on the secondary side of the transformer and compensated by instruments or loss calculations to the primary side of the transformer, as provided in the Department’s Rules. 

h.     Selection of Rates 
        Customers shall be placed on the applicable rate under Schedule A-1 if demand, as determined for the Facilities Charge, drops below 30 kW.
