What You'll Learn
Time-of-use plans can help reduce overall costs
Time-of-use plans are designed to help reduce your overall electricity costs. These plans are based on the understanding that electricity rates fluctuate throughout the day, with higher rates during peak hours when demand is high, and lower rates during off-peak hours when demand is low. By choosing a time-of-use plan, you can take advantage of the varying rates and adjust your electricity usage accordingly.
Typically, electricity is cheaper late at night or early in the morning, as these are off-peak hours when fewer people are using electricity. On the other hand, peak hours usually occur during the afternoon and early evening, when people are at home from work and school, and using more electricity. For example, on the East Coast of the US, peak hours often fall between 2 pm and 6 pm during the summer months when air conditioning systems are in heavy use.
Time-of-use plans allow you to benefit from lower rates during off-peak hours by encouraging you to shift your electricity usage to these times. For example, you could run high-energy appliances, such as laundry machines or dishwashers, overnight or before peak hours begin. Similarly, you can reduce your energy usage during peak hours by turning off appliances, lights, and electronics when not in use, or by adjusting your thermostat by a few degrees.
These plans can be especially beneficial if you have solar panels installed on your property. Solar panels generate the most electricity during off-peak hours when the sun is high in the sky, and this solar energy can be used to power your home or sold back to the grid during peak hours. Some utilities even offer special time-of-use rate plans for customers with solar panels or battery storage systems, providing additional cost savings.
However, it's important to note that time-of-use plans may not always result in significant cost savings. Before switching to a time-of-use plan, compare the rates with your current plan to determine if the off-peak rates are significantly lower. Additionally, consider your flexibility in changing your electricity usage habits, as it may not be feasible to eliminate electricity usage during peak hours entirely. Nonetheless, time-of-use plans can be a great way to reduce your overall electricity costs if you're able to align your usage with the off-peak hours.

Off-peak electricity is usually cheaper at night
Time-of-use (TOU) plans are becoming increasingly popular with utility companies and allow customers to take advantage of lower rates during off-peak hours. These rates are designed to give customers the option to save money by adjusting their usage patterns to use more electricity during off-peak hours and less during on-peak hours. On-peak periods are when the demand for electricity is highest, and the costs to generate and deliver energy are greater, so the rates are higher. Conversely, when demand is low, the cost of electricity is generally lower because there is less stress on the electricity grid, and cheaper energy sources, such as wind power, are more available.
For example, in Colorado, the on-peak rate is 2.7 times higher than the off-peak rate during the summer months. Similarly, in California, the highest rates are between 4 pm and 9 pm on weekdays, and the daily basic charge is $0.53, with no minimum daily charge or baseline credit.
If you're looking to save money on your electricity bill, it's worth considering a TOU plan and adjusting your habits to use more electricity during off-peak hours, such as running your laundry or dishwasher overnight. However, it's important to note that TOU plans can be complicated, and you should first compare the rates under a TOU plan with your current rate plan to ensure you'll make significant savings.

Peak hours vary by region and season
The time of day that electricity rates are cheapest depends on your location and the off-peak periods utilities operate. Peak hours vary by region and season, and the exact timing of these peak hours depends primarily on your location. For example, on the East Coast of the US, it tends to be hottest after 2 pm, so the peak hours in this region are often from 2 pm to around 6 pm during the summer months. In contrast, during the winter, peak hours shift to the early morning as homeowners and businesses turn up the heat to keep their living and work spaces comfortable.
Time-of-use (TOU) plans, where the rate you pay for electricity depends on the time energy is drawn from the grid, are becoming increasingly popular for utilities to offer to their residential customers. Under TOU rates, you get billed different amounts for usage at different times of the day. These rates are designed to give electric utility customers options to save money by adjusting their use patterns to use more electricity when the rate is reduced and less during on-peak hours. On-peak periods are set when demand is highest and costs are greater to generate and deliver energy. When demand is low, the cost of electricity is generally lower because there is less stress on the electricity grid and cheaper energy sources are available. For example, wind-generated electricity is typically more available and less expensive to produce and distribute overnight.
In California, some time-of-use rate plans include a demand charge, which encourages businesses to spread their electricity use throughout the day. When businesses spread their electricity use throughout the day, California's supply of electricity is more reliable. This demand charge is calculated using the 15-minute interval in each billing month when a business uses the most electricity. If businesses can lower their highest usage in that 15-minute interval, they can save money.

Solar panels can be beneficial for those on Time-of-Use rates
The cost of electricity varies throughout the day and night, with the highest rates typically charged between 4 pm and 9 pm on weekdays. These periods of high demand are known as "peak hours", and the rates during these times are often double the price of "off-peak" hours.
Time-of-Use (TOU) plans are designed to give customers the option to save money by adjusting their electricity usage patterns to take advantage of off-peak rates. Under TOU rates, customers are billed different amounts depending on the time of day. While TOU rates are not mandatory, they are becoming increasingly popular, and in some places, such as California, solar panel customers are required to sign up for TOU rates.
It is important to note that the effectiveness of solar panels can be impacted by factors such as shading from trees or other obstructions. Before switching to a TOU plan, it is recommended to compare the current rate you are paying for electricity with the TOU rates offered by your utility provider. Additionally, consider the flexibility of your everyday habits and whether you can realistically adjust your electricity usage to align with off-peak hours.

Demand charges encourage businesses to spread electricity use
Energy consumption is usually the most expensive during peak hours, which are typically in the afternoon and early evening. This is when most people are using electricity, so there is more stress on the electricity grid, and the cost of electricity is higher.
Demand charges are fees paid by commercial and industrial customers based on their highest usage in a 15-minute or one-hour interval during the billing period. They can constitute 30% or more of a customer's bill and are designed to give electric utility customers the option to save money by adjusting their usage patterns. Demand charges can be the most expensive part of a monthly electric bill, and they are based on the rate of energy consumption, which is measured in kilowatts (kW).
Demand charges encourage businesses to spread out their electricity use by modifying their energy loads or changing which equipment is running simultaneously. For example, a bakery that turns on its ovens, lights, and HVAC each morning can generate a spike in demand by powering these appliances at the same time. By staggering these activities, the bakery can reduce its peak demand and minimize demand charges.
Businesses can also reduce demand charges by scheduling energy-intensive activities during off-peak hours. For instance, running electric pumps for irrigation at night instead of during high-demand periods can lower demand charges. Similarly, using renewable energy sources, such as solar power, during the daytime can help businesses take advantage of lower electricity rates while the sun is shining.
