What are demand charges?
Demand charge. Demand is the rate at which you consume electricity – or the amount needed to power your business at any given point in time. Demand charges are based on the highest level of electricity you demand at one time during the billing period and at the time of day it’s needed by your business.
How do demand charges work?
To help lower peak demand, consider:
- Installing energy-efficient equipment and finding other smart ways to reduce your energy usage in business.
- Downsizing your equipment to fit the job.
- Rescheduling your company's most energy-intensive activities at lower-load times of the day.
How does APS calculate demand charge?
It is your demand (your highest hour of energy use during on-peak hours, measured in kilowatts or kW), multiplied by a charge per kilowatt. The charge per kilowatt varies by season. For example, in summer the demand charge is $16.870 per kilowatt on our Time-of-Use 4pm-7pm with Demand Charge plan.
How do demand charges work?
The demand charge is a monthly fee that you pay as part of the cost of maintaining the electric utility's infrastructure required to deliver electricity to your building.

How to save on energy costs?
You can save on your energy costs by shifting your usage from on-peak to off-peak hours, such as: Setting your dishwasher to run on a delay cycle. Running your pool pump during the day before 3 p.m. Do your laundry on the weekends.
How does demand charge work?
Instead of total consumption, a household’s demand charge is based upon the maximum amount of power required over a single hour (or fifteen minute period) in a given month. Because your demand charge is set based upon your maximum hourly power requirement, there is less incentive to reduce your overall usage throughout the month, but rather to adjust how much electricity you require at once. If you’re on a demand charge electric rate, the only way to decrease your electric bill is to use less power all at once.
Why are demand charges being proposed?
Utilities are proposing demand charge rates for a reason: to incentivize electricity customers to think not just about how much electricity they use over an entire month, but about when and how much they are using at once.
What happens to demand charge on electric bill?
As a customer on a demand charge rate, you will still be billed for your monthly consumption as well as for your demand. However, in comparison to a purely volumetric bill, the balance of your bill will shift from being driven by your overall consumption to being driven by your peak demand. To offset the increase in the fixed charge portion of your electric bill, the increase in the demand charge is necessarily met with a reduction in the volumetric rate, meaning consumption will be billed at a much lower rate than on a typical residential electric bill.
How do utilities recover costs?
Providing all of these services costs money. Historically, utilities recovered costs through volumetric billing – billing each customer for the quantity of electricity they use in a given month or year, measured by consumption (kWh). But with demand charges, utilities hope to shift to billing customers based upon their share of the total peak demand for energy on the system, measured in power requirement, kW instead of kWh.
What is a volumetric electric bill?
A typical volumetric electric bill is made of fixed and variable charges that are combined into two separate pieces of a bill: a transmission and distribution charge (T&D) that keeps the poles and wires that connect houses to the grid operational; and a supply charge that represents the cost of generating the electricity we consume.
What is demand charge?
At its core, a demand charge shifts the charge on your electric bill from how much electricity you consume over an entire month to the maximum electricity you need at a single point during the month. Demand charges have historically been used for larger industrial electric customers, but are beginning to appear for residential customers.
How much does solar energy reduce your electricity bill?
If, for instance, your solar array is sized to provide 80 percent of your generation every month, then you will reduce your electricity bill by 80 percent every month, because you avoid purchasing electricity from the grid.

Why is the price of electricity higher during the weekdays?
The price is greater during the on-peak hours of 3-8 pm on weekdays, and lower at all other times. This is because between 3 and 8 pm more energy is used. As a result, more energy needs to be produced and energy therefore costs more, while during off-peak hours less energy is used and it costs less.
Is energy lower during off-peak hours?
Days are divided into off-peak and on-peak hours, for purposes of these plans. During off-peak hours, the price for energy is lower than the standard plans; it is higher during on-peak hours. You can save money on a time-of-use plan by using less energy during the higher-cost hours.

How to determine demand charge?
To determine the demand charge for a given month, the maximum power demand is multiplied by the demand charge rate of the prevailing utility rate. While the exact billing approach varies by utility, some rate structures include multiple types of demand charges, with higher charges during hours of peak demand, and lower charges during “partial-peak” or “off-peak” hours (time of use rates). For customers, whose utility rates include them, demand charges can contribute significantly to monthly electric bills.
How does solar energy affect demand?
How Does Solar Affect Demand Charges? The impact of solar is relatively straightforward when it comes to consumption charges: by producing electricity from a solar installation, a commercial customer can reduce the amount of energy they must buy from the utility and thereby reduce utility bills.
Why do utilities charge demand?
This is because utilities must maintain enough generation and distribution capacity to meet the needs of all customers during the points in time when the most energy is drawn from the grid (such as a hot day when most customers are using air conditioning). This means that a large amount of expensive equipment, such as power plants, must be kept on standby for these rare peak demand periods. Through demand charges, customers that draw a lot of power over short periods of time contribute more to the costs of building and maintaining the necessary infrastructure needed for peak times.
