Did you know adjusting when you use electricity can cut your energy bill by 20–40%? With time-of-use (TOU) tariffs, utilities charge different rates based on demand—rewarding those who shift usage to cheaper “off-peak” windows. Pair this strategy with a NextG Power Home Battery to automate savings and maximize renewable energy use. In this guide, we’ll decode peak vs. off-peak times, reveal the cheapest hours to power up, and show how TOU tariffs and home batteries put money back in your pocket.
What Are Peak and Off-Peak Electricity Times?
Electricity demand fluctuates daily, creating peak (high-demand, high-cost) and off-peak (low-demand, low-cost) periods:
Peak Hours
When: Typically 4 PM – 9 PM on weekdays (when homes/offices use the most power).
Cost: 2–3x higher than off-peak rates.
Why: High demand strains grids, raising wholesale prices.
Off-Peak Hours
When: Usually 10 PM – 6 AM and weekends.
Cost: 50–70% cheaper than peak rates.
Why: Low demand = surplus energy sold at discounts.
Example TOU Rates (U.S. Average):
| Period | Cost per kWh |
|---|---|
| Peak |
0.40 |
| Off-Peak |
0.15 |
How Time-of-Use (TOU) Tariffs Work
TOU plans incentivize shifting energy use to off-peak hours. Key features:
Dynamic Pricing: Rates change hourly based on grid demand.
Savings Potential: A family could save $300+/year by running appliances at night.
Smart Meter Required: Tracks usage in real time.
When Is the Cheapest Time to Use Electricity?
The cheapest electricity times vary by region and utility, but generally:
Late Night to Early Morning: 10 PM – 6 AM (ideal for charging EVs, dishwashers, laundry).
Weekends/Holidays: Many utilities treat weekends as off-peak all day.
Pro Tip: Use your utility’s app or website to view exact TOU schedules.
How to Capitalize on Off-Peak Rates
Shift High-Energy Tasks:
Run washing machines, dryers, and dishwashers overnight.
Charge EVs during super off-peak hours (e.g., 12 AM – 5 AM).
Use Smart Plugs/Timers: Automate devices to power on during cheap rates.
Pre-Cool/Pre-Heat: Set thermostats to cool/heat homes before peak rates kick in.
Invest in a NextG Power Home Battery:
How It Works: Charge the battery during off-peak hours (when rates are lowest) and use stored energy during expensive peak times.
Benefits:
Slash peak-hour usage by up to 90%.
Seamless integration with solar panels for 24/7 renewable energy.
Automate savings with smart energy management software.
Real-World Savings: A Case Study
A California household saved $450/year by:
Shifting 70% of their energy use to off-peak hours.
Installing a smart thermostat to pre-cool their home by 2 PM.
Adding a NextG Power 10 kWh Home Battery, which reduced peak-hour grid reliance by 80%.
Supercharge Savings with a NextG Power Home Battery
A home battery isn’t just backup power—it’s a TOU tariff game-changer:
Maximize Off-Peak Rates: Store cheap nighttime energy for daytime use.
Avoid Peak Penalties: Power your home during 4–9 PM without grid costs.
Solar Synergy: Pair with rooftop solar to store excess energy and avoid selling it back at low rates.
ROI: Most users break even in 5–7 years, with savings accelerating as energy prices rise.
Example:
Battery Cost: $8,000 (after incentives).
Annual Savings: $1,200 with TOU + solar.
Payback Period: 6.6 years.
Drawbacks of TOU Tariffs
Risk of Higher Bills: Unchanged habits (e.g., evening AC use) can backfire.
Limited Flexibility: Missed savings if your schedule conflicts with off-peak windows.
Is a TOU Tariff Right for You?
Best For:
Night owls or households with flexible schedules.
EV owners needing overnight charging.
Solar owners storing energy in batteries (like NextG Power) for peak times.
FAQs
Q: How does a home battery help with TOU savings?
A: It stores off-peak or solar energy for use during peak hours, bypassing high rates.
Q: Can I use a NextG Power battery without solar?
A: Yes! Charge it via the grid during off-peak hours and discharge during peak times.
Switching to a time-of-use tariff isn’t just about saving money—it’s about smarter energy use. By aligning your habits with off-peak hours and investing in a NextG Power Home Battery, you’ll reduce bills, ease grid strain, and achieve energy independence.
