Demand Charges: What Are They?

Demand Charges Explained: What Are They, and How Do They Work?

Understanding the basics of energy billing is the first step to properly managing your facility’s energy usage. Commercial electricity bills consist of more than the total energy expenditure over a set billing cycle — they also include demand charges. 

In certain rate classes, territories and months of the year, demand charges could make up more than half of your bill.

This post will explain the demand charges in kilowatts (kW) on your electricity bill, how it relates to electricity usage in kilowatt-hours (kWh) and how you can use this information to benefit your business. 

 

What Is a Demand Charge?

The rate at which energy is consumed is a demand charge. These charges, measured in kilowatts, are based on the amount of energy consumed within a demand interval — these stretches last 15 or 30 minutes — and represent the high costs electric companies have to pay for transmission and generating capacity that, for the most part, sits idle. 

Demand charges can significantly rack up monthly electric bills for customers whose utility rates include them. These charges generally apply to industrial and commercial customers, who tend to have higher peak power demand or peak loads than residential customers. 

A utility company will scrutinize the maximum amount of power that a customer used in any interval during the billing cycle to apply demand charges. 

Consumers will know the power demand they are allowed to have based on the utility rates specified by their provider. Exceeding this demand for several months in a row can result in higher demand charges and a changed rate. 

 

How Can You Benefit From Understanding a Demand Charge Rate? 

Understanding the role demand charges play in your electricity bill can help you lower costs. These charges can comprise a significant portion of your statement as a commercial customer. 

If not managed, demand charges can make up a significant portion of your energy bill. In some cases, it can even exceed the amount spent on usage. With this in mind, monitoring and controlling your peak usage can help you lower your electricity bill. You can do this by managing your highest points of demand. Identify peak times and spread out your usage throughout the day to avoid spiking usage at one point in time.

 

How Do Utilities Charge for Electricity?

To determine the demand charge for a given month, utilities multiply the maximum power demand by the demand charge rate of the prevailing utility rate. 

A utility’s precise approach to billing will vary. For example, some rate structures include a multitude of demand charges, with lower rates during off-peak or partial-peak hours. 

 

Usage vs. Demand Charges

Your energy bill can be made up of both usage and demand charges. Usage charges are determined based on the average amount of energy used over a time period, while demand charges are calculated based on energy use at one point in time. If your demand at one time is much higher than your typical energy usage, it will probably reflect in your bill.
