How Free Nights and Weekends Plans Work
Free nights and weekends plans give you zero-cost electricity during specified hours—usually evenings, overnight, and weekends. The catch? Higher rates during peak hours.
Plan structures:
| Plan Type | Free Hours | Trade-off |
|---|---|---|
| Free Nights | 8pm-6am (or 9pm-6am) | Higher daytime rates |
| Free Weekends | Saturday & Sunday | Weekday rates apply |
| Free 3-Day Weekends | Friday evening - Monday morning | Premium weekday rates |
The "free" electricity isn't technically free. Providers build the cost into your peak-hour rate:
- Use 20¢/kWh power all day → you're overpaying
- Shift 50%+ of usage to free hours → you come out ahead
The arbitrage: Can you use more power when it's free than when it costs 18-22¢/kWh? For night owls and shift workers, the answer is often yes.
TDU Charges Still Apply (The Fine Print)
Here's what the advertisements don't emphasize: TDU delivery charges still apply during "free" hours.
Your Transmission and Distribution Utility charges about 5-6¢/kWh for delivery regardless of when you use power. That charge doesn't go away during free hours.
So "free nights" really means "5-6¢ nights" after TDU charges. Still a good deal compared to 18-20¢ peak rates, but not actually free.
Example calculation (1,000 kWh monthly, 60% shifted to free hours):
| Usage Period | kWh | Rate | Cost |
|---|---|---|---|
| Free hours (TDU only) | 600 | ~5.5¢ | $33 |
| Peak hours | 400 | 20¢ | $80 |
| Total | 1,000 | — | $113 |
Compare to flat 12¢/kWh plan: $120 total
The free nights plan saves about $7/month—only if you shift enough usage.

Who Benefits Most from Free Nights Plans
Free nights plans aren't for everyone. They work best for specific lifestyles:
| Lifestyle | Why It Works | Free-Hour Advantage |
|---|---|---|
| Night Shift Workers | Active at night, sleeping during day | Cooking, laundry, charging—all free |
| EV Owners | Significant charging needs | Fuel your car for just TDU costs |
| Weekend-Only Home | Work outside home weekdays | Free weekend plans align perfectly |
| Pool Owners | Pool pumps run 4-6 hours daily | Program pump for overnight runs |
| Night Owl Families | Naturally stay up late | More usage falls in free hours |
Night Shift Workers: If you're home during the day sleeping and active at night, you naturally use more power during free hours.
EV Owners: Electric vehicles take significant power to charge. Set your EV to charge overnight during free hours and you're essentially fueling your car for just TDU delivery costs.
Pool Owners: Pool pumps run several hours daily. Program your pump to run overnight (free) instead of afternoon (peak rate). Easy savings.
Who Should Avoid Free Nights Plans
These plans can cost you more if your usage pattern doesn't match:
| Lifestyle | The Problem | Better Alternative |
|---|---|---|
| Work-From-Home | Computer, AC, appliances running all day | Flat-rate fixed plan |
| Daytime-Heavy Families | Kids home, retirees, activity peaks in day | Low fixed rate |
| Heavy Summer AC | AC runs hardest during peak hours | Avoid unless willing to precool |
| Low-Usage (<700 kWh) | Not enough volume to shift meaningfully | Simple low-rate plan |
Work-From-Home Professionals: If you're home running a computer, AC, and appliances all day, you're using peak-rate power constantly. A flat-rate plan is almost certainly cheaper.
Heavy AC Users in Summer: Texas AC runs hardest during hot afternoons—exactly when peak rates apply. Unless you're willing to precool your home at night and let it warm during the day, summer bills can spike dramatically.
Low-Usage Households: If you only use 500-700 kWh monthly, you don't have enough usage volume to shift meaningfully. A simple low-rate fixed plan is better.
How to Calculate If Free Nights Will Save You Money
Before signing up, do the math for your household:
Step 1: Get Your Usage Data
Register at SmartMeterTexas.com. Download your 15-minute interval data for the past month. You'll see exactly when you use power.
Step 2: Calculate Your Usage Split
Add up kWh used during free hours (e.g., 8pm-6am). Divide by total usage. If 50%+ falls in free hours, these plans might help.
Step 3: Model Both Scenarios
Free nights plan calculation:
- Free hours kWh × TDU rate (~5.5¢)
- Peak hours kWh × peak rate (~20¢)
- Add monthly fees if any
Flat-rate alternative:
- Total kWh × flat rate (e.g., 11¢)
- Add monthly fees if any
Step 4: Add a Cushion
Peak rates can change. Usage patterns shift seasonally. Build in 10-15% cushion before committing.
Tips for Getting the Most from Free Time Plans
If you decide a free nights plan fits your lifestyle, maximize your savings:
Quick wins for free-hour optimization:
| Strategy | What to Do | Savings Potential |
|---|---|---|
| Shift Appliances | Dishwasher, laundry, dryer during free hours | High |
| Pre-Cool Home | Lower thermostat before peak starts | Medium-High |
| Charge Overnight | All devices, EVs, power tools | High |
| Smart Automation | Programmable thermostats/plugs | Medium |
| Monitor Bills | Track first 2 months closely | Critical |
Shift Discretionary Usage: Run dishwasher, laundry, and dryer during free hours. Use delay-start features.
Pre-Cool Your Home: Lower thermostat during free hours (morning before peak starts) so your house is cold heading into the hot afternoon.
Use Smart Home Automation: Smart thermostats, smart plugs, and programmable timers automate the shift without constant manual management.
Monitor Your Bills Closely: Your first two months will show whether the plan actually saves money. If peak-hour usage is higher than expected, switch to a flat-rate plan before you're locked in.
