Fuel Charge/Retail Energy Adjustment Charge

The fuel charge encompasses the cost of fuel to produce electricity and the cost of electricity we buy from other entities. These costs are reduced by the profit we make selling electricity to wholesale entities, such as neighboring utilities, municipalities and power marketers. 

Westar submits an estimate of the fuel charge to the Kansas Corporation Commission. The charge adjusts quarterly.

  • Annually, Westar will compare the estimates with the actual costs and make an adjustment to ensure customers are paying only actual fuel costs. 
  • The adjustment will be paid or credited over the next 12 months.

Cold Weather Rule and heat moratorium

The Kansas Corporation Commission has established the Cold Weather Rule for Kansas residential customers who cannot fully pay their winter electric bill. The Cold Weather Rule will be in effect from November 1 to March 31.

How it works

For residential customers, the Cold Weather Rule generally prohibits any disconnection of service when the local National Weather Service forecasts that the temperature will drop below 35 degrees or will be in the mid-30s or colder within the following 48 hours.

In order to avoid having service disconnected when the temperatures are forecasted to be above 35 degrees or to reconnect service regardless of temperature, a customer shall:

  • Inform Westar if you are unable to pay the bill in full.
  • Provide enough information to allow Westar to make a payment agreement.
  • Make an initial 1/12 payment of the total energy charges, plus the full amount of any required disconnect and reconnect fees, plus applicable deposit. Pay agreements allow the unpaid balance to be divided and paid in equal amounts over an 11 month period. Customers may pay bills during the payment agreement under an average payment plan in addition to the portion of the unpaid balance each month.
  • Apply for federal, state, local or other assistance funds for which the customer is eligible.
To ensure customer safety, Westar will:
  • Inform customers of organization where funds are available to assist with payment of utility bills.
  • Contact customers prior to disconnection:
  • When an account is past due, we mail a disconnect notice along with the current statement. The disconnection notice indicates the date payment needs to be received to avoid interruption of service. From when the disconnect notice is sent, it is approximately 10 business days until we will disconnect service.
  • A few days before service is scheduled to be disconnected, we will place a collection call from 800-383-1183. If you are concerned the call is not legitimate, please hang up and call 800-383-1183.
  • The service person in the field will knock on the door and attempt to collect before physically disconnecting service. Service persons generally will not enter the home. Payment should be made to Westar Energy. Company employees wear a shirt with the Westar logo, oftentimes have a hard hat, and will not hesitate to show company identification.
  • Customers may also take part in third party notification if there are problems receiving bill statements.
Heat Moratorium

Westar Energy keeps a close eye on forecast temperatures. We may voluntarily stop disconnection activity if the Heat Index is 105 degrees or above during the day and 80 degrees or above as an overnight low. Normal collection/disconnection activity will resume when temperatures drop.

Kansas Corporation Commission (KCC)

Under Kansas law, the Commission oversees the rates utilities charge their customers and the service provided.

The KCC protects public interest through impartial and efficient resolution of all jurisdictional issues. The KCC sets the rates Westar charges its customers. It also reviews the service and safety of public utilities in Kansas.

Complaint Procedure

Should you have questions or concerns regarding electric service, Westar hopes that you will contact us and give us the opportunity to find a solution before exercising your right to file a complaint with the KCC.

If we are unable to resolve your concerns to your satisfaction, you may file a complaint with the KCC.

Federal Energy Regulatory Commission (FERC)

The Federal Energy Regulatory Commission, or FERC, is an independent agency that regulates the interstate transmission of electricity. As part of that responsibility, FERC: 

  • Regulates the transmission and wholesale sales of electricity in interstate commerce.
  • Reviews certain mergers and acquisitions and corporate transactions by electricity companies. 
  • Reviews the siting application for electric transmission projects under limited circumstances.
  • Reviews officer and director positions held between top officials at utility companies and certain firms with which they do business.
  • Protects the reliability of the high-voltage interstate transmission system through mandatory reliability standards.
  • Monitors and investigates energy markets. 
  • Enforces FERC regulatory requirements through imposition of civil penalties and other means. 
  • Administers accounting and financial reporting regulations and conduct of regulated companies.
