What components are done to calculate my electric bill?

General Power Service TGSA2 is defined as:

  • Monthly usage setting a Max Demand of 50kW or greater.
  • Any customer who is a GSA1 customer meeting the above criteria will be moved to the GSA2 class.
  • Any customer establishing service must complete a BCES Load Sheet.


New Commercial and Industrial Rates for GSA2/GSA3 Class Summary
Effective October 1, 2015

Benton County Electric System is moving toward a cost causation rate philosophy; modeling our electric rates after TVA’s new Strategic Pricing Model. TVA will begin billing on October 1, 2015. At this time we will also align our retail electric rates based on the TVA model.

This is a great opportunity for your industry or business to use techniques to manage and minimize your energy charges. All billed items are a pass through of TVA charges except your Base Customer Charge and Monthly Maximum Demand charge. These two charges are used to cover the infrastructure and cost associated with delivering electricity to your location, known as distribution cost recovery. At any given time BCES has to be able to serve the demand of your organization at its full transformer capacity size throughout its infrastructure.


What will change?

Your bill will only consist of 6 billing factors defined below; and all detail billing will be provided on page two of your bill. Base Energy Rates vary monthly due to the TVA Monthly Fuel Cost (TMFC).

Monthly Bill Components

  • Base Customer Charge
      • Base Charge to deliver and maintain power to your service location.
  • Maximum Demand (kW)
      • The Customer’s maximum billing demand for any month shall be the highest average during any 60-consecutive-minute period of the month of the load metered in kW.  
      • The Customer’s maximum billing demand for any month shall in no case be less than the higher of the currently effective contract demand or the highest maximum billing demand established on or after October 1, 2014.
  • CP Maximum Demand (kW)
      • The Customer’s contribution to Benton County Electric’s Peak during the exact date and time of BCES’s System Demand for the highest level of energy consumed in 60 minute intervals.
      • TVA Pass-through of cost to BCES
  • CP Maximum Demand during On-Peak Period (kW)
      • The Customer’s contribution to Benton County Electric’s Peak during On-Peak period at the exact date and time of BCES’s System Demand as indicated on the bill.
      • On Peak Period for Demand
          • April-October –Summer 1PM-7PM
          • November-March—Winter 4AM-10AM
      • BCES is billed by TVA for our Monthly Maximum Demand during the On-Peak Period for the highest level of energy consumed in 60 minute interval
      • TVA Cost Pass-through to BCES
  • On-Peak Energy (kWH)
      • 1000 Watts of energy consumed in one hour = 1 Kilowatt Hour
      • Energy consumed during the following hours:
        • November – March 4AM-10AM
        • April – October 1PM -7PM
        • **April/May/October/November--Transition Rates
        • Weekends/NERC Holidays, usage will be counted as Off-Peak Energy

          • Manage Existing Service
          • Power Billing Information and History
      • TVA Cost Pass-through to BCES
  • Off-Peak Energy (kWH)
  • Reactive Power Penalty if applicable (Power Factor)
      • Power factor is a correctable item that is a measure of how efficient your organization uses electrical energy. Typically, power factor is corrected by customer installing capacitors on site.
      • A poor power factor means BCES must deliver more energy than necessary to do the same amount of work efficiently and causes a greater demand on the system overall. Measured in KVA by your meter.
      • BCES can assist customers with action items necessary to correct their reactive power penalty through our Comprehensive Services Program with TVA.


Our cost causation rate philosophy is to give customers the opportunity to manage their energy needs. Previously, the rates were shared among the power service classes. We believe this rate model will offer customers options to minimize and manage their energy needs.

In What Way can my Organization Change to reap the largest benefits from this rate change?


      • Minimize demand loads during BCES Max Peak load time or BCES Max Peak Load during On-Peak Period time
      • Minimize energy (kWh) usage during on-peak intervals.
      • If your organization cannot change your schedules or maintenance windows to satisfy some of the conditions, then the Energy (kWh) and CP Demand (kW) are a direct pass through at cost from TVA.


How will BCES assist my organization?


      • BCES will post and provide historical information regarding our peak load times for the CP Maximum Demand and CP Maximum Demand during the on Peak Period for your organization’s review to curtail energy load when necessary. The customer is ultimately in control of their energy needs and demands.
      • The historical data will be available via our website at under “Manage Existing Service”
      • BCES will be available upon request to discuss energy management strategies and utilize and/or make available any available resources through TVA to provide the analysis and assistance you may need.


If you have any additional questions, please contact our office at 731-584-8251.


CP= Coincident Peak

kW= Kilowatt = 1,000 Watts (Demand, highest level of energy consumed during a 60 minute interval)

kWh= Kilowatt Hours, Energy Consumed by customer. 1,000 watts consumed in one hour equals 1 kWh

Pass-through= TVA Direct bill charge with no additional charges added by BCES.

TMFC = Total Monthly Fuel Cost
