Understanding Your Electricity Bills and the Basics of Energy Billing

The first step to understanding your electricity bills is to define them. An electricity bill is a periodic statement reflecting the cost of the electricity consumed within a specific timeframe. Usually, this timeframe is a month or even two, but it can vary based on the plan and provider you choose. You will encounter specific industry terms or jargon when examining your electricity bills.

Unfortunately, understanding the electricity bill is only possible if you know these terms or jargon. For instance, the billing cycle is one of the terms you are likely to encounter if you are trying to optimize your energy consumption habits. So, before we discuss the various components of your electricity bill, let's first discuss the essential electric company jargon.

Common Terms and Jargon Used by Electric Companies

Below are some standard terms and jargon you must familiarize yourself with to understand your electricity bills and expenses fully. 

Billing Cycle

The billing cycle is the period for which your energy usage is measured. Although the most common billing cycle is one month, it is only sometimes the case.

Meter Multiplier

When the usage is too large to display on the meter, a "meter multiplier" is applied to recalculate the actual energy consumption. In such cases, the meter shows a fraction of the actual use, and the electric company uses the meter multiplier to arrive at the correct reading. 

Meter Reading Type

It indicates how the reading of your electric meter is obtained. There are three ways to acquire this reading, which are listed below. 

  • Directly by a utility representative (Actual)
  • Self-reported by the customer (Customer), 
  • Based on past data (Estimated)

Metering Charge

It is the fee associated with maintaining and monitoring your electricity meter to ensure accurate energy usage tracking.

Purchased Electricity Adjustment

It is an adjustment that corrects discrepancies between the rate charged for you and the actual cost to the supplier used by some electric companies.

Customer Charge

A fixed administrative fee is designed to cover the cost of customer service, independent of your energy usage.

Consumer Education Charge

It is a monthly fee charged by some companies for providing consumers with ongoing education about their bills, selecting electricity providers, and learning energy-efficient practices.

Distribution Charge

Distribution charges are often fees related to the infrastructure that delivers electricity to your home, including local wiring and transformers.

Environmental Cost Recovery Adjustment

Electric companies may charge you compensation for the utility's environmental initiatives or activities aimed at environmental improvement.

Franchise Cost

It is the charge electric companies use to offset the utility fees paid to the municipality for the privilege of operating within its jurisdiction.

Energy Efficiency Programs

Electric companies recover the costs associated with mandated green initiatives to promote energy conservation and efficiency via this fee. 


Breaking Down Your Electric Bill

The simple way to break down your electric bill is to split it into two—supply charges and delivery charges. The logic behind these charges is the same as when you place an Uber Eats order, where you pay for the food and the delivery. Similarly, your electric bill consists of payment for the energy producer and the company that delivers the energy from the provider to your home.  

Supply Charges

The supply charge is the cost of generating electricity. Two types of entities can supply electricity to your household or business. 

Your local electricity utility company that is responsible for delivery electricity in your area. They typically offer a default supply rate that adjusts periodically with the market for those customers who do not switch to a competitive energy supplier. (Eg: Eversource in Massachusetts)
Or a competitive supplier. (Eg: Clearview in Massachusetts)

Fun Fact: In the deregulated areas of Texas, customers are actually mandated to switch to a competitive supplier. Their local electricity utility companies do not offer a default supply rate. 

Delivery Charges

The second key element of your bill is the delivery charge. It encompasses the following charges. 

Transmission Charges: This fee supports the transmission system's construction, maintenance, and operation, transporting electricity from power generators to local distributors.
Distribution, Operations, and Service Charges: These include the costs of delivering power to homes, maintaining infrastructure, customer service, and enhancing grid reliability.
Public Policy Charges: These charges fund initiatives such as energy efficiency, renewable energy, electric vehicle programs, and distributed solar projects.

It is critical to note that delivery service rates can vary depending on the location. For instance, electricity rates in Texas differ from those in other parts of the U.S. due to its deregulated energy market. In a deregulated market, electricity rates in cities such as Houston and Dallas are likely to be lower and highly competitive compared to other regions.

What are the Factors Affecting Your Electric Bills?

Several factors can significantly influence the total amount on your electricity bill. These factors can broadly fall into three categories as listed below.

  • Energy consumption habits or patterns.
  • Utility provider's pricing structure.
  • Energy efficiency measures.
