Review: TXU Free Nights & Solar Days plan

TXU’s “Free Nights & Solar Days 18” is the most expensive Time-of-Use electricity plan we currently track, costing the average homeowner nearly double the best fixed-rate plan.

Lately you can’t watch TV for an hour without seeing a commercial for this plan. It touts “free” electricity from 9 p.m. until 6 a..m., with the rest as renewable solar and wind. Together, that’s the trifecta of red flags in our “How to Shop for Electricity in Texas” article. But let’s start with the math…

For simplicity, we took TXU’s own EFL usage and average price claims at face value. Then we compared them to the cheapest 18-month, fixed-rate, 100%-renewable plans on PowerToChoose.org using our RateGrinder tool, including typical month-to-month usage variations:

TXU Free Nights & Solar Days (DFW/Oncor area)
Avg monthly usage (kWh)
500 1000 2000
Average rate (¢/kWh) 15.2 13.7 12.9
18-month cost  $1,368  $2,466  $4,644
 – Lowest-cost fixed-rate competitor  $707  $1,318  $2,544
 = TXU cost premium  $661  $1,148  $2,100
+93% +87% +83%

Like most “free” weekends/nights plans, TXU’s Free Nights & Solar Days jacks up the base rate more than enough to compensate for the free periods. In this case, it’s upwards of 18.5 ¢/kWh after TDU charges. For comparison, the best alternatives above averaged <7.7 ¢/kWh annually. So a house that averages 1000 kWh/month usage would pay an extra $1,148 over 18 months. If you try to change your mind, you’ll encounter a $295 cancellation fee, the highest of any 18-month plan we currently track.

Can savvy consumers make up the difference by deferring their electricity usage until the free periods? Not likely. As the largest electricity retailer in Texas, TXU knows how much their customers use from 9 p.m. to 6 a.m. Their EFL “average rate” math above already assumes 32.7% is free. Their press release claims “customers on these plans received nearly 40 percent of their energy usage for free”1. But even that extra 7.3% barely dents the 83%+ cost premium.

Think you’re up for deferring YOUR usage enough to come out ahead? It is theoretically possible. Sweltering without air conditioningBut you’ll be plenty hungry waiting in the dark until 9 p.m. to cook canned soup for dinner because you have no fridge or freezer. And without AC your stagnant, algae-filled backyard pool will offer little relief from the Texas heat. Get the picture? Yes, your dishwashing and laundry can be put off until nighttime, but that difference is relatively small. If you really want to do the math on your house’s usage, we’ve posted a tool to help in our “Indexed and Time-of-Use Plans Roundup“.

Finally, TXU has added “Solar Days” to their prior Free Nights offering, via purchases of solar power and solar and wind renewable energy credits (RECs). But as “Green Energy Plans: The Reality” notes, RECs in Texas are sadly too cheap to do much more than boost retailer profits. Perhaps TXU’s “purchases of solar power” include more meaningful Power Purchase Agreements with generators, but that information is lacking. (If so, we welcome TXU to provide details in the comments below.)

Don’t pay the price for marketing gimmicks like Free Nights & Solar Days. To find the lowest cost options for your home, just plug your monthly electricity usages into TPG’s RateGrinder tool. You won’t find a cheaper rate easier anywhere else.

The Problem with ‘Power To Choose’

Shop Compare Lose

PowerToChoose.org oversimplifies electric plan shopping in a way that is neither effective nor honest. Its superficial search results ignore the hidden rate games that retailers have played for years. As a result, the Texas PUC’s “official and unbiased” site misleads trusting consumers into overpaying by hundreds or thousands of dollars per year.

Consider this example: The average Texas home uses from 840 kilowatt-hours (kWh) of electricity in April to 1740 kWh in August, or about 1200 kWh/month annually. For such a home, PowerToChoose lists these 12-month plan options:

Can you tell the cheapest plan from the one that costs an extra $576? At 1000 kWh/month, all ten plans claim retail rates well below the wholesale price of ~7.5 ¢/kWh. Some users might notice different prices for 500- and 2000- kWh/month and mentally average those three prices over their actual monthly usages. But that approach is futile, and here’s why…

Texas retail electricity providers can define any pricing profile they want in a plan’s Electricity Facts Label (EFL). The EFL must list the price at 500-, 1000-, and 2000 kWh/month, but pricing at any other usage (even 999- or 1001 kWh) can vary wildly. The chart below shows the full rate profiles for the first six plans above. All charge a 3.2 ¢/kWh “teaser” rate in the rare case you use exactly 1000 kWh in a month, which is how they win the search game. But your usage and rate vary each month, which is how they make money.

You cannot tell a good plan from an overpriced gimmick from just the three “Price/kWh” numbers on sites like PowerToChoose. Even deciphering the full rate profile often isn’t enough: Outdated delivery charges, non-cumulative charges, non-recurring fees, and partial billing cycles add layers of confusion and expense that are rarely discussed, except by us.

The Right Way

The only effective way to compare plans is to compute your total cost across each of your usages (NOT their average). This means reading the rate terms in each EFL’s fine print and making a spreadsheet. Doing so reveals that Plan #11 — on page 2 of the results — is the cheapest. Plan #9 is close, but the others on the first page cost up to $580 more.

Plan # Annual Cost Amount You’d Overpay
1  $    1,440  $        375 +35%
2  $    1,299  $        234 +22%
3  $    1,590  $        525 +49%
4  $    1,414  $        349 +33%
5  $    1,180  $        115 +11%
6  $    1,116  $          51 +5%
7  $    1,305  $        240 +22%
8  $    1,528  $        463 +43%
9  $    1,069  $             4 +0%
10  $    1,645  $        580 +54%
11  $    1,065  $           – +0%

All of this is arguably more work than countless Texans should have to do to get a competitive electric rate. That’s why we built and maintain Texas Power Guide’s RateGrinder tool to do the heavy lifting for you. Click below to give it a try. By educating and enabling consumers to find their electric plan, we hope you can put the time and money you save to better use.

Although PowerToChoose serves a valuable role as the marketplace for many low cost plans, consumers today have better options. PTC’s crippled search engine and guidance to compare pricing at only 1000 kWh ignore longstanding evidence that such an approach is broken.1 2 As a publicly-funded site with a stated mission to “protect customers”, they have the power to choose to offer a better solution.

This article was updated on 2/7/2018.

Oct ’18 update: After years of neglect, on 8/20/18 the PUC updated PowerToChoose.org to limit the number of plan listings per REP and filter out usage-dependent rates by default. We applaud these changes, as the average PTC user is now less likely to fall victim to gimmicky rates.

However, the changes don’t fix the underlying EFL price disclosure issues noted above, so gimmick rates remain one click away on PowerToChoose, and are still prominently featured on dozens of other shopping websites. Time will tell what, if any, effect the PUC’s changes have on average retail prices, but additional reforms are still needed.
