Best electricity plan for a home battery in Dallas–Fort Worth (2026): time-of-use & free-nights explained
If you own a home battery in the Dallas–Fort Worth area—or are installing one soon—you have a powerful tool at your disposal. But that tool is only as effective as the "fuel" you buy for it. Pairing your battery with the right electricity plan can transform it from a simple backup device into a money-saving engine.
However, the Texas electricity market is complex. While a Time-of-Use (TOU) or "Free Nights" plan can supercharge your savings, the wrong plan can cost you more than a standard fixed-rate contract.
Here is an independent, plain-English guide to navigating DFW electricity plans with a home battery in 2026.
How Texas retail choice works in DFW
Most of the Dallas–Fort Worth metroplex sits within the Oncor delivery territory. Oncor maintains the poles and wires, but they do not sell you the electricity. Because Texas is deregulated, you must choose a Retail Electricity Provider (REP).
This gives you the power to shop for rates and plan structures that fit your lifestyle—and your battery.
Important Check: Not all of North Texas is deregulated. Some cities are served by municipal utilities or co-ops (like Garland or Denton) that do not offer retail choice. If you live in one of these areas, you cannot switch providers and must use the rate offered by your city.
The 3 main types of electricity plans
When shopping for a plan to pair with a battery, you will generally encounter three structures. Understanding the difference is critical to your monthly bill.
1. Fixed-rate plans
This is the standard "set it and forget it" option. You pay the same rate per kilowatt-hour (kWh) every hour of the day, regardless of demand.
- Pros: Predictable; easy to budget.
- Cons: You miss out on opportunities to buy power when it is cheapest (like overnight).
2. Time-of-use (TOU) plans
TOU plans charge different rates depending on the time of day. Electricity is typically cheaper during "off-peak" hours (late night to early morning) and more expensive during "on-peak" hours (late afternoon and evening, when demand is high).
- Pros: Rates align perfectly with battery storage logic.
- Cons: Requires you to be mindful of when you are pulling from the grid vs. your battery.
3. Free nights / free weekends plans
These are aggressive variations of TOU plans. They offer electricity at $0 or a very low rate during specific windows (e.g., 9:00 PM to 6:00 AM). To offset this, the daytime rate is usually significantly higher than the market average.
- Pros: Maximum savings if you can shift almost all usage to the free window.
- Cons: Highest risk. If you run out of stored battery power during the day, you pay a premium price.
Comparison: plan types for battery owners
| Plan Type | How it Prices | Best For | Watch-Outs |
|---|---|---|---|
| Fixed-Rate | Same price 24/7 | Homeowners who want simplicity and predictability. | You cannot "arbitrage" rates; the battery only saves you money during outages or if you have solar. |
| Time-of-Use (TOU) | Low price at night; High price in afternoon/evening. | Battery owners who can charge overnight and discharge during peak hours. | You must ensure your battery capacity covers your peak usage to avoid high bills. |
| Free Nights | $0 (or near $0) at night; Very high price during the day. | Heavy battery users who can stay off the grid entirely during daytime hours. | Daytime rates are often inflated. If the battery drains too early, savings vanish instantly. |
How a battery works with TOU and free-nights
The economic magic of a home battery lies in energy arbitrage.
If you are on a TOU or Free Nights plan, your battery acts like a savings account for electricity. You "deposit" energy into the battery when the price is low (overnight). Then, when the price spikes in the late afternoon (typically 2:00 PM to 6:00 PM in Texas), you withdraw that energy to power your home. A Texas virtual power plant can add another source of value when compatible programs are available.
With Solar:
If you have solar panels, the strategy evolves. You can store your excess solar generation during the day instead of selling it back to the grid for a low credit. You then use that stored power in the evening when the sun goes down but electricity rates are still high.
The honest math: why "free" isn't always free
It is tempting to sign up for a "Free Nights" plan, but you must do the math. Providers do not give away electricity for free; they make up for it by raising the daytime rate or adding higher base charges (monthly service fees).
To determine if a plan works for you:
- Check the EFL: The Electricity Facts Label (EFL) is the legal disclosure document. Look at the "Average Price per kWh" at 500, 1000, and 2000 kWh usage levels.
- Analyze Your Usage: Look at your past 12 months of bills. How much energy do you use during the specific "free" or "off-peak" windows versus the expensive "on-peak" windows?
- Battery Capacity: Be realistic. Can your battery cover your home's load for the entire peak duration? If your battery dies at 4:00 PM but peak rates last until 6:00 PM, you will pay the high rate for the remaining two hours. Use the battery size and cost calculator to explore the capacity behind that plan.
Availability and terms change frequently. Always compare the current EFLs on the state's Power to Choose website or directly with REPs. Do not rely on advertised marketing alone.
Step-by-step: how to pick the right plan
- Verify Your Utility: Confirm you are in the Oncor territory (deregulated). If you are in a municipal utility area, you cannot switch.
- Review Your Data: Download your historical usage data from your current provider's account portal.
- Filter for TOU/Free Nights: Search for plans that offer low rates overnight.
- Read the EFL: Ignore the big marketing number. Look at the pricing breakdown for the specific months (summer vs. winter) and usage tiers.
- Calculate the Break-Even: Ensure the savings from using stored battery power during peak hours outweigh the higher daytime rates or base charges of the plan. Compare the result with the full installed cost of a DFW home battery.

Electricity plans for home batteries
What is the best electricity plan if I have a home battery?
There is no single "best" plan for everyone, but generally, Time-of-Use (TOU) plans offer the best balance for battery owners. They allow you to charge cheaply at night and discharge during expensive afternoon peaks without the extreme risk of the inflated daytime rates found in "Free Nights" plans.
Do free-nights plans actually save money?
They can, but only if you can shift the vast majority of your energy consumption to the free window. For a battery owner, this means your battery must be large enough to power your home through the entire expensive daytime period. If you draw from the grid during the day on a free-nights plan, you will likely pay more than you would on a standard fixed-rate plan.
Can I charge my battery on free nights and use it during the day?
Yes, this is the intended strategy. You charge the battery from the grid during the free overnight window (e.g., 9:00 PM to 6:00 AM) and then switch the home to run off battery power during the day. However, you must monitor your battery state of charge; if it depletes before the free window starts again, you will be charged the high daytime rate.
Do I need solar to benefit from a TOU plan?
No. You can benefit from a TOU plan with just a battery by charging from the grid. However, solar adds another layer of savings. With solar, you can charge your battery with the sun for free during the day and use that power in the evening, reducing the amount you need to buy from the grid even during off-peak times.
How do I compare Texas electricity plans fairly?
Ignore the "3-month teaser rates" and look at the Electricity Facts Label (EFL). Specifically, look at the average price per kWh at 1000 kWh (a common usage benchmark) and check for cancellation fees or monthly base charges. For battery owners, calculate the specific cost of power during the "charging" window versus the credit you effectively get by avoiding power during the "peak" window.
Note: This guide is for informational purposes only and does not constitute financial advice. Electricity rates and plan availability change constantly. Always verify current terms and conditions in the EFL before signing a contract.
