How to save money on your electricity bill
The cost of electricity fluctuates, and knowing when to use power-intensive appliances can help you save money. Typically, off-peak hours, when electricity is cheaper, run from 8 pm to midnight and midnight to 4 pm, while on-peak hours, when electricity rates are highest, span from 4 pm to 8 pm. However, the exact timing depends on your location, and the off-peak periods utilities operate. For example, Southern California Edison offers a TOU-D-PRIME rate plan with different peak hours in the summer and winter.
Take advantage of off-peak hours
Use energy-intensive appliances during off-peak hours. Many appliances, including dishwashers, washing machines, and dryers, have scheduling functions, so you can set them to run ahead of time. If you own an electric car, charge it at night during off-peak hours.
Reduce your usage during peak hours
Avoid running high-energy appliances during peak hours, typically in the evening when people get off work. If you can't avoid using appliances during peak hours, try to limit your usage. For example, spread out your laundry loads and turn off lights and appliances when you don't need them.
Improve your home's energy efficiency
- Seal air leaks: Seal air leaks with weather strips and caulk to save up to 20% on your energy costs.
- Replace your air filter: Replacing your air filter every three months can help extend the life of your HVAC system and make it run more efficiently.
- Use natural light: Take advantage of natural light during the day instead of turning on lights.
- Use energy-efficient light bulbs: Energy-efficient LED light bulbs can save households around $225 in energy per year and last up to 25 times longer than incandescent lights.
- Install dimmer switches: Install dimmer switches in the rooms you use the most to reduce your light usage.
- Adjust your thermostat: Dialing down your thermostat by 7-10 degrees for eight hours a day can help you save 10% on your electric bill each year. You can do this manually or buy a programmable thermostat.
- Use ceiling fans: If you're working from home, utilize ceiling fans, which can make a room feel up to 4 degrees cooler with less energy.
- Hang dry your laundry: Instead of using a dryer, consider hang-drying your laundry, especially during the summer months.
- Use solar power: Consider investing in solar panels, which can lead to thousands of dollars in electricity savings over 30 years.
- Use a smart power strip: Plug your devices and appliances into a smart power strip to prevent "energy vampires" from drawing power when not in use.

What are peak hours?
Peak hours refer to the times of day when electricity consumption is highest. These hours vary by region, utility company, and season.
During peak hours, electricity rates are at their highest. This is because, during these times, there is more pressure on the power grid, and it costs more to produce the additional electricity required to meet the demand. Power companies thus charge more for electricity during peak hours.
Peak hours typically occur in the afternoons and evenings, when people are turning on their lights, watching TV, and using appliances like dishwashers and washing machines. In the summer, peak hours usually fall between noon and 6 pm, when businesses, schools, and malls are cranking the air conditioning.
On the East Coast of the US, for example, peak hours are often from 2 pm to 6 pm, while off-peak hours are from 6 am to 2 pm. In contrast, the Central time zone has peak hours from 1 pm to 5 pm and off-peak hours from 5 am to 1 pm.
It's important to note that peak hours can also depend on factors like the weather, generating capacity, and demand patterns in a specific area.

What are off-peak hours?
The cost of electricity is constantly fluctuating, but knowing what time of day to power your appliances can save you money. Off-peak hours are periods when electricity prices are cheaper, and fewer people are trying to access the grid. This is usually during the afternoon and at night, typically from 8 pm to 4 pm, and midnight to 8 am. During these hours, electricity is cheaper because there is lower demand on the grid, and it comes from abundant sources like large wind and nuclear plants.
Demand is higher during peak hours, which usually span from 4 pm to 8 pm, as people come home, run their appliances, and adjust their thermostats. This is also the time when people are turning on their lights, firing up their TVs, and settling into their homes for the night, which requires more electricity than usual. Peak hours also vary by region, utility company, and season. For example, in the Eastern time zone, peak hours are typically from 2 pm to 6 pm, whereas, in the Central time zone, they are from 1 pm to 5 pm.
You can take advantage of off-peak rates by programming smart appliances like washers, dryers, and dishwashers to run during these hours. Additionally, you can set your thermostat a little higher in the summer and lower in the winter before leaving the house for the day. If you own an electric car, you can also plan to charge it at night during off-peak hours.
By timing your energy-intensive tasks to off-peak hours, you can save money on your monthly electricity bill.

How to take advantage of off-peak rates
Off-peak hours are when electricity demand is low, usually in the afternoon and at night. Typically, off-peak hours span from 8 pm to 4 pm, and sometimes from 9 pm to 9 am, and are when electricity is cheapest. On-peak hours usually span from 4 pm to 8 or 9 pm and are when electricity rates are highest.
- Timing your energy-intensive tasks to off-peak hours can help you save money on your monthly energy bill. This includes running large appliances such as dishwashers, washing machines, and dryers, which have scheduling functions that allow you to set the time for them to run ahead of time.
- Charging electric vehicles during off-peak hours can be a great way to take advantage of lower rates.
- Using energy-efficient appliances, such as smart thermostats, can help you save money, regardless of the time of day.
- Installing solar panels can lead to significant electricity savings over time, as you generate your own power instead of buying it from a utility company.
- Using a backup battery to store electricity purchased during off-peak hours can help you use that cheaper energy during peak hours.
- Adjusting your thermostat during peak hours can also help reduce costs. Setting your air conditioner to 78 degrees or above, especially during peak hours, can help keep costs down.
- Utilizing "sleep" mode on electronics such as computers and TVs ensures they aren't using unnecessary electricity during peak hours.
- Unplugging appliances not in use during peak hours is another way to minimize electricity usage during the most expensive times.
- Using motion sensors for your lights can ensure they only turn on when you are home and moving around, reducing unnecessary electricity usage during peak hours.
- Waking up early to start household chores that require electricity can help shift your energy usage to off-peak hours.
- Checking with your electricity provider to see if they offer time-of-use plans and when their off-peak hours are can help you plan your energy usage accordingly.

Time-of-use plans
Time-of-use (TOU) plans are a rate structure that shifts the cost of electricity to be more dependent on your peak usage as a utility customer. The wholesale market price of electricity varies throughout the day based on factors including supply, demand and weather. By offering you, as a customer, prices that differ based on time periods, retail providers give you the chance to adjust your usage to shift it to lower-priced times.
TOU plans are beneficial for customers who can manage the timing of their electricity use to make the rates work in their favour. Demand for electricity isn't consistent during the day. People use more electricity when businesses are operating and when HVAC systems are running. At night, most people are sleeping, and most businesses are idle. Demand typically goes down during this time. With a TOU rate plan, the price you pay for energy depends on when the energy is being used. Your rate will generally be lower during off-peak hours, such as at night and on weekends, meaning you can reduce your electricity costs by performing your most energy-intensive tasks during these times.
Electricity companies offer TOU plans because it helps them avoid buying more electricity during times of high demand when it can get quite expensive. TOU plans can also help flatten demand throughout the day, causing less stress on the electrical grid infrastructure.
In places like Michigan and Missouri, TOU plans are mandated for residential customers. In California, anyone who gets solar panels installed must switch to a TOU plan, and there are optional plans for people with electric vehicles and other home electrification. Southern California Edison offers one of the most popular TOU plans in the country. The rates differ by time period, weekday, and season. For example, on summer weekdays, there are just two time periods: On-Peak, from 4 pm to 9 pm, and Off-Peak during all other hours.
