Free Nights & Weekends Plans — Worth It?

How Free Nights Plans Work

Free nights plans are a type of time-of-use plan. Instead of charging one flat rate around the clock, they split the day into two windows: off-peak (night) and on-peak (day). During the off-peak window, the energy charge on your bill drops to zero. During the on-peak window, you pay a higher-than-normal rate.

The typical split looks like this: nights run from 9 PM to 6 AM on weekdays, and some plans extend free hours through the entire weekend. The exact hours vary by provider, so always check the Electricity Facts Label (EFL) before you sign up.

Here’s the part that trips people up: “free” only applies to the energy charge. Your TDU delivery charges — the cost of moving electricity through the wires to your home — still apply 24 hours a day, 7 days a week. Delivery charges run about 3.5-4 cents per kWh depending on your utility. So even at 2 AM, you’re still paying something for every kilowatt-hour you pull from the grid.

The Catch

The daytime rate on a free nights plan is significantly higher than what you’d pay on a standard fixed-rate plan. That’s how the math works for the provider. They’re giving you free energy at night, so they make it up during the day.

On a typical fixed-rate plan, you might pay 10-12 cents per kWh around the clock. On a free nights plan, the daytime rate often lands between 15-20 cents per kWh. That’s a 50-100% premium during peak hours.

Now think about what actually runs in your home during the day:

• Air conditioning accounts for 40-60% of a typical Texas summer electric bill. Your AC runs hardest between noon and 7 PM, right in the middle of the on-peak window. You can’t shift this to nighttime without coming home to a sauna.
• Refrigerator runs 24/7. Half its cycle falls during peak hours.
• Cooking — dinner prep, oven use — almost always happens during peak hours.
• Laundry and dishwasher can be shifted to nighttime, but they’re a relatively small part of your total consumption.

The appliances that consume the most electricity are the ones you can’t easily move to off-peak hours.

The Math — When They Save Money

Let’s run the numbers with a concrete example. Say your home uses 1,200 kWh in a month.

Standard fixed-rate plan at 11 cents per kWh: 1,200 kWh x $0.11 = $132.00 per month

Free nights plan (assuming 40% of your electricity falls in the free window, 60% during the day):

• Night: 480 kWh x $0.04 (delivery only) = $19.20
• Day: 720 kWh x $0.17 (energy + delivery) = $122.40
• Total: $141.60 per month

That’s $9.60 more per month on the free nights plan. Not less — more.

The 40/60 split is realistic for a household that sleeps at night and works during the day. Your AC, fridge, and cooking don’t care about your plan structure.

To actually break even on a free nights plan, you’d need about 55-60% of your total electricity consumption to fall in the off-peak window. That’s a hard number to hit for most households. It means running your AC primarily at night, doing all laundry and dishes after 9 PM, and being away from home most of the day so nothing is drawing power.

Who Actually Benefits

Free nights plans aren’t a scam. They’re just designed for a specific kind of household. You might actually save money if:

You work night shifts. If you sleep during the day and are active at night, your natural schedule aligns with off-peak hours. Your AC runs less during the day because you keep the house warmer while you sleep, and your lights, TV, and cooking all happen during the free window.

You have solar panels. Solar panels generate electricity during the day, offsetting your highest-cost hours. At night, when your panels produce nothing, the electricity is free. This combination can genuinely slash your bill — but only if your provider offers both solar buyback and free nights on the same plan.

You charge an EV overnight. An electric vehicle charging at home can add 300-400 kWh per month to your bill. If all of that charging happens during the free window, that’s real savings. At $0.04/kWh delivery-only versus $0.11/kWh on a fixed plan, you’re saving $21-28 per month just on the car.

You’re an empty nester who travels. If your home sits mostly empty during the day — minimal AC, no cooking, no laundry — and you’re mainly home in the evenings and mornings, more of your consumption naturally falls into the off-peak window.

The Verdict

For the typical Texas household, free nights plans cost more, not less. The higher daytime rate eats up the nighttime savings because most of your electricity consumption happens during peak hours. Air conditioning alone makes the math hard to overcome in summer.

A straightforward fixed-rate plan at a competitive rate is usually the cheaper and simpler option. You don’t have to think about when you run the dishwasher or whether your AC is costing extra because it kicked on at 3 PM.

If you do think your household fits one of the scenarios above, run the math with your actual electricity patterns before switching. Pull your smart meter data (available from your TDU’s website) to see what percentage of your consumption falls during the off-peak hours. If it’s consistently above 55-60%, a free nights plan could work for you. If it’s below that, stick with fixed.
