Electricity Shopping Gotchas

Be wary of the games some electricity retailers play

Texas electricity shopping is a minefield of gimmicks and gotchas. The average household overpays by ~$400 annually, while savvy retailers keep inventing new ways to squeeze higher margins from their customers.

To help level the playing field, we list the most common gotchas to watch out for below. How many are you aware of?

Energy-only rates

Each month, you pay both your chosen Retailer for electricity and your local Utility to deliver it. All Retailers bill for delivery on your Utility’s behalf, yet some quote their energy-only costs (without delivery) to appear cheaper. Always compare quotes with delivery charges included. If they aren’t listed, move on.

Usage-dependent rates, credits, or charges

Sites like PowerToChoose condition shoppers to compare prices only at 500-, 1000-, or 2000 kWh/mo, despite their actual usage varying widely over the year. Retailers capitalize with rate gimmicks that appear cheap at those exact usages while charging more overall.

Example: A plan charges a flat $80 for the first 1000 kWh plus 15¢/kWh for usage over 1000 kWh.

That’s only 8 ¢/kWh if you use exactly 1000 kWh/mo. But it’s 10.3 ¢/kWh at 1500 kWh/mo, 11.5 ¢/kWh at 2000, and a whopping 16 ¢/kWh if you only use 500 kWh.

“Non-cumulative” rates

A more extreme version of the above, where using one kWh more can change the rate for your entire month’s usage.

Example: $80 for usage up to 1000 kWh, or 15¢/kWh for usage over 1000 kWh.

Using 1000 kWh costs $80, but using 1001 costs $150.15 (vs. $80.15 in the case above).

Partial billing cycles

If your plan has usage-dependent charges, mind your start date. Most plans count usage per pre-defined “billing cycles”. If you start on a mid-cycle day, you’ll get partial first- and last cycles, or 13 billing cycles for a 12-month plan. Depending on the plan, that can cost you more.

Example: You use ~1500 kWh/month and pick a plan that credits you $95 for using at least 1000 kWh/billing cycle.

If you start (and end) the plan in the middle of a cycle, your first and last [half] cycles will only include ~750 kWh usage and you’ll forfeit one $95 credit.

“Free” nights/weekends/cash back/…

“Free” is the most powerful word in marketing, but there’s usually a catch.

Free Nights and/or Weekends plans tease savings for consumers who shift their usage to off-peak hours. But inflated daytime rates lead most to pay higher average rates. The same goes for plans that bundle gift cards, thermostats, or other freebies. Always do the math.

100% renewable

Wind and solar energy have clear CO2 and pollution benefits, so many Retailers offer them exclusively or as an upsell option.

Unfortunately, the Renewable Energy Certificates (RECs) that underpin virtually all such plans in Texas are completely ineffective. A 100% renewable plan may cost you more, but it makes no difference in the transition to clean energy. Unless it’s your cheapest option, skip the “green” plan.

Wholesale rates

“Wholesale” plans can be good for certain off-peak users, but they’re not for everyone. Real-time rates are highly volatile, and summertime price spikes can quickly erode months of savings. These plans require focused effort and/or home automation to shift usage to lower-priced periods, and higher usage to offset their monthly membership costs.

“Free” plan advice

The psychology of “free” applies to where you shop, as well. All electricity shopping sites must earn money to cover their expenses. If you aren’t paying them to shop on your behalf, Retailers are paying them to sell you plans at higher rates. Guess which costs you more?

Name recognition

Advertising and high-profile sponsorships cost money. So it ‘s no surprise that the Retailers we’re most familiar with tend to charge higher rates for the exact same electricity. (It may be a surprise that those same companies also sell it under less-known sibling brands at a lower price.)

Non-yearly contracts

Summer month electricity costs Retailers extra, which they pass on to you. To appear cheaper, some offer plans that avoid or underweight summer, such as 6- or 18-month plans spanning October to March.

To compare plans of different lengths, always factor in estimated costs for any months they don’t have in common. More details.

Variable rates

With few exceptions, “variable rate” plans are expensive and unpredictable. Retailers can change pricing at their sole discretion, so rates tend to spike dramatically after the promotional billing cycle.

“Bait and switch”

Some Retailers post good deals on shopping sites, then tempt you with a barrage of seemingly cheaper rates when you visit their website to sign up. The new offers are usually of the usage-dependent type (see above) and more expensive, so stay the course to find your original target.

Non-recurring fees

Retailers’ Terms of Service documents detail one-time fees for non-payment, manual payment, disconnection, etc. You can avoid most of these with Autopay, e-billing, and timely payments; otherwise some can get quite expensive.

“Tease and squeeze”

Did you successfully navigate all of the above to nab a cheap rate? Retailers can still count on you forgetting your renewal months or years down the road. When you do, they’ll quietly roll you into an expensive month-to-month plan until you notice.

Indexed and Time-of-Use Plans Roundup

New for Nov 2019! Texas Power Guide now has a more powerful spreadsheet calculator to compare Time-of-Use electric plans. Download it here for Excel, then paste in your full electricity usage history from SmartMeterTexas.com to see how you’d fare with Griddy, Free Nights, and others.

 

Electricity plans like Reliant Truly Free Weekends, TXU Free Nights, and Griddy all charge based on when you use electricity, but beyond that they’re very different. We do the math to see which are gimmicks and which deliver the goods.

Risk vs. Reward

When shopping for electricity, most consumers choose plans with a “Fixed” rate over the contract term. Such plans offer predictable bills and relatively simple math. In theory, however, they do not offer the lowest cost.

To offer you a fixed rate for a period of time, retailers must first estimate how much they’ll pay for your electricity. The wholesale price of electricity depends on many variables. These include the price of natural gas, weather changes like heat waves, hurricanes, and wind, and consumers’ daily patterns of electricity use. As a result, electricity pricing can vary a lot: from -260% to over +11,000% of the ~2.6 ¢/kWh average just last year. Facing these uncertainties, retailers add safety margin to their cost estimates so they don’t undercharge customers and go bankrupt. The longer the contract, the more uncertainty and risk, so the more they have to add to your rate.

Houston Electricity Price History

To offer lower rates, some retailers create plans that shift some or all of their pricing risks to you. “Indexed” plans base their pricing on underlying market indices like the monthly price of natural gas. “Time-Of-Use” (TOU) plans generally increase their pricing during late afternoon peak use periods. And some plans do both with rates based on the real-time wholesale price of electricity, which changes every 5 minutes. To the extent they transfer pricing variation risk to the consumer, these plans have the potential to offer lower prices. (They’re also more difficult for consumers to quantify, but Texas Power Guide is here to help with that.)Houston Electricty Prices vs Time of Day

Plan Comparison

To see how they stack up, we pitted 9 indexed and/or Time-of-Use plans from PowerToChoose.org and elsewhere against each other. We ran the numbers using the past twelve months of pricing data matched with the actual usage of two Houston-area homes. Home #1 is a 1-story, 2-occupant house with an average consumption of ~1130 kWh/month — about the Texas state average. Home #2 is a 2-story, 4-occupant house with a pool and average consumption of ~2100 kWh/month. Neither home participated in an indexed or TOU plan during the sampling period, so their owners weren’t shifting their normal consumption behavior. We’ll discuss the practicality of doing so in the results.

For comparison, we also included the current best 12-month Fixed rate plan per our RateGrinder tool.  While the best plan from one year ago would make a better comparison, those details weren’t available. Energy prices are slightly higher in 2017 than 2016, which unduly benefits Indexed/TOU plans computed using last year’s pricing.

We did not include plans that PowerToChoose.org categorizes as “Variable”. Unlike Indexed plans tied to a public index, retailers can often change pricing on Variable plans at their sole discretion. Finding details of price histories can also be challenging. As a result, Variable plans don’t meet our threshold for either predictability or transparency.

Per TPG’s philosophy, all our data and calculations are posted here [Note: Newer version available, see top of article.] If you export your home’s usage data from SmartMeterTexas.com, you can paste it into our file to see your own results. We also include historical data on wholesale electricity and natural gas prices to lend insight into the frequency and severity of [usually weather-related] price spikes.

The table below summarizes our results. Time-of-Use plans are in blue. Plans indexed to the monthly price of natural gas are in purple. Plans indexed to real-time (15-minute) electricity pricing are in green.

Results: Indexed and Time-of-Use Plans Comparison

Retailer / Plan $/year ¢/kWh $/year ¢/kWh
[Best 12-month Fixed rate plan] $1,002 7.4 $1,881 7.4

Reliant PowerTracker $1,411 10.4 $2,535 10.0
TXU Energy MarketEdge $1,499 11.0 $2,698 10.6
Reliant Truly Free Weekends 24 $1,519 11.2 $2,789 11.0
TXU Free Nights 24 (9 p.m.)
TXU Free Nights & Solar Days 18
$1,861 13.7 $3,368 13.3

Observations

For the average Texas home (~ Home #1), the best 12-month fixed rate undercut the Indexed/TOU options by $114 – $859/yr.

For those with higher usage and a stomach for short-term risk, however, Griddy Energy may be worth a look. New to Texas in April, Griddy’s prepaid daily plan offers the real-time wholesale rate (plus TDU charges) for $9.99/month and 2.9%+30¢/payment. The fees overshadow the wholesale benefit at low or average usages. But above ~2000 kWh/month usage Griddy starts to compete with the better 12-month fixed rates. Griddy also offers the most potential for consumers to shift their consumption for more savings — including occasional negative pricing — with a phone app for real-time pricing, forecasts, and alerts. If you’re willing to assume the risk of pricing disruptions (see first chart, above) in exchange for a lower long-term bill and/or less frequent shopping, Griddy may work for you. That said, Griddy is brand new and TPG hasn’t directly sampled their service, so stay tuned for more. If you have, let us know your experience in the comments.

Beyond that, there’s currently little else in the Houston market worth considering:

Volt EP‘s Signature Index Plan is the other product indexed to the wholesale price of electricity, but on a monthly postpaid basis. With a different fee structure, it is cheaper than Griddy only for lower-than-average usages. Unfortunately, that’s the space where fixed-rate plans outcompete both.

Three “Free Weekends” options from Champion, Direct Energy, and Reliant are nominally Time-of-Use plans, but not in the traditional sense of passing through higher afternoon pricing. Instead, they’re largely marketing tactics to lure customers into higher average rates obscured by trickier math. As such, they are frequently panned on the Internet. Only an extremely weekend-focused consumer might come out ahead of the better fixed-rate options.

The three plans indexed to the NYMEX Natural Gas Futures index also performed poorly, due to their unremarkable pricing.

Finally, TXU‘s identically-priced Free Nights 24 (9 p.m.) and Free Nights & Solar Days 18 plans cripple their usage-shifting potential with a staggering 13+ ¢/kWh average cost, ranking worst in our survey.

Bottom line

For those seeking the lowest cost, a shorter-term fixed-rate product such as those found with our RateGrinder tool is still the best bet. But for risk-tolerant consumers with higher usage or a desire to capture savings by shifting their consumption, Griddy may be a worth a look.

Article updated 8/6/17 to include TXU’s Free Nights & Solar Days 18 plan, which as of that date has identical pricing terms as the Free Nights 24 (9 p.m.) plan.

Article updated 8/7/18 to remove 3-month fixed rate plan comparison data, since the analysis did not capture the total cost of successive 3-month options at seasonally varying pricing.

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:

Power To Choose default results
Default results from PowerToChoose.org (2/5/2018)

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.

Example electric plan rate profiles
Rate Profiles for Plans #1 – #6, and Average Texas Monthly Usage

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.

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.
