Direct Energy Twelve Hour Power Review: Free 9 p.m. to 9 a.m., 34.5 Cents the Other 12 Hours

The biggest free window in Texas

Direct Energy's pitch is one sentence long: free electricity every night from 9 p.m. to 9 a.m. Twelve full hours. Half of every day. No other free-nights plan we have reviewed offers a window that large; TXU's free nights and Reliant's both cover less of the clock. As of August 2026 the plan sells in 12-month and 24-month terms; directenergy.com pitches the 24 up front, and the 12-month EFLs on Direct Energy's own document server are dated as recently as August 1, 2026.

Direct Energy is not a scrappy independent making a desperate offer. It has been owned by NRG Energy since January 2021, when NRG paid $3.6 billion for it. NRG also owns Reliant, Green Mountain Energy, and Cirro, which means one company now sells free-time structures under several brand names, including Green Mountain's Free Nights. The structure keeps getting rebuilt because it keeps working, and it works because the number that funds it is hard to find.

Twelve Hour Power has two siblings on the same frame: Free Power Weekends, free from 6 p.m. Friday to 11:59 p.m. Sunday, and Free Days, free from 9 a.m. to 5 p.m. every day. Direct Energy has also marketed 24-month "On Us" versions that bundle an Amazon Prime membership on top of the free window. As of August 2026 that campaign page had been taken down; the plain Twelve Hour Power 24 stands in its place. Wherever the Prime bundle resurfaces, remember that a membership is a real cost, and its cost lives in the rate.

Claims vs. fine print

Four claims on the front. Four footnotes on the back. Here they are, side by side.

The rate Direct Energy shows only after your ZIP code

directenergy.com will not quote you a price until you hand over a ZIP code. But the Electricity Facts Labels sit on Direct Energy's own document server, and we pulled four of them, one for each major utility territory where the plan sells. They agree with each other almost to the decimal.

The Oncor EFL, dated August 1, 2026: energy charge 34.5 cents per kWh from 9 a.m. to 9 p.m., 0 cents from 9 p.m. to 9 a.m., base charge $9.95 a month, Oncor delivery $4.06 a month plus 6.0 cents per kWh billed on daytime usage only. Advertised average at 1,000 kWh: 23.5 cents. CenterPoint (dated June 1, 2026) runs a 35.4-cent day rate and averages 23.6 cents. AEP Texas Central (May 15, 2026): 34.8 cents, averaging 23.5. AEP Texas North (March 20, 2026): 35.0 cents, averaging 23.5. Every version carries a $150 termination fee, a 12-month term, and 22% renewable content against a 37% statewide average.

One more finding from our side: Twelve Hour Power does not appear in the live marketplace feed we run across all five Texas utility territories. Direct Energy lists its flat and bill-credit plans there, Bright Secure 12 at 15.8 cents all-in on Oncor among them, but the free-nights plan sells only through Direct Energy's own site. When a provider keeps a plan off the comparison shelf, side-by-side math is exactly what the plan is being protected from. Note what that means: Direct Energy's own Bright Secure 12 undercuts Twelve Hour Power's advertised 1,000-kWh EFL average by 7.7 cents.

How the free window works

This is a time-of-use plan, which we explain in full in our time-of-use guide. Your smart meter records usage in intervals. Anything you use between 9 p.m. and 9 a.m. bills at 0 cents, and, unusually for this plan class, the utility's delivery charges are waived during the window too. The EFL is explicit: "the customer will not be billed for any TDU delivery charges during the Designated Free Period." Credit where due; most free-window plans keep charging delivery on the free hours.

Everything else about the frame is standard. The $9.95 base charge bills every month regardless of when you use power. Usage from 9 a.m. to 9 p.m. bills at the full 34.5-cent energy charge plus delivery. A provisioned smart meter is required. And the timing matters more than the hour count suggests: the paid window holds the hours when homes use the most, the afternoon air-conditioning slog and the 6-to-9 p.m. peak of cooking, laundry, and screens. Free starts at 9 p.m., after the expensive part of your evening is already on the bill.

The EFL also carries an interval-data clause worth reading twice. If the utility fails to record complete smart-meter data, usage can be estimated from history, or reported as zero and re-billed later once real data arrives. On a flat-rate plan a data gap barely matters. On a plan where the price of a kWh depends entirely on when you used it, estimation and after-the-fact re-billing are how your bill gets revised weeks later.

Do the math on 12 free hours

Start with the EFL's own honesty. The window covers half the clock, but Direct Energy's average-price math assumes 45% of your usage lands in it, not 50%, because homes run heavier during the day: afternoon air conditioning and the evening rush through 9 p.m. outweigh anything your house does at 3 a.m. That 45% assumption is fair, even mildly generous. And with it, the EFL's own bottom line at 1,000 kWh is 23.5 cents.

Hold that against the market on the day we published. The cheapest flat-rate, no-gimmick Oncor plan on our live feed was 12.8 cents all-in at 1,000 kWh. At the EFL's own assumption, Twelve Hour Power costs about $235 a month at 1,000 kWh against $128 on the flat plan: a $107-a-month premium, roughly $1,280 a year, for the feeling of free. A daytime kWh on this plan runs about 40.5 cents once delivery is added, more than three times the flat plan's all-in rate.

To merely tie the 12.8-cent flat plan, you would need about 71% of your monthly usage between 9 p.m. and 9 a.m., against the 45% Direct Energy itself assumes. To tie Direct Energy's own Bright Secure 12 at 15.8 cents, about 64% at night. To tie the 7.0-cent bill-credit leader, about 85%, a profile that belongs to almost nobody with a pulse and a daytime life. We ran the same math on every free-window plan we have reviewed, from Champion's weekends to Reliant's nights, and the pattern is the pattern: the free hours are funded by the hours you cannot avoid. A bigger window just needs a bigger day rate to pay for it, and 34.5 cents is what half a day free costs.

What to do instead

For contrast, here is the live Oncor market on the day we published (August 7, 2026). The cheapest all-in plan at 1,000 kWh was 7.0 cents per kWh, but it earns that number with a bill credit that punishes low-usage months; bill-credit plans cut both ways. The cheapest flat plan with no credits, no tiers, and no free windows was 12.8 cents at 1,000 kWh, 10.7 cents under Twelve Hour Power's own advertised average. Every plan below publishes its full Electricity Facts Label before you enroll.
