Most months, a Texas electricity bill is about as interesting as a parking receipt, same range, same shrug. Then the weather does something nobody planned for, and that whole assumption falls apart in a matter of hours. February 2021 is still the clearest example of just how fast.
When the Grid Nearly Broke
A cold snap that severe doesn’t come around often. Power plants froze. Natural gas wellheads froze. And right as that supply was disappearing, millions of Texans were cranking their heaters as hard as they’d go just to stay warm.
The grid operator ended up minutes away from a total collapse. Regulators’ fix was blunt: push wholesale electricity prices all the way to the legal ceiling, around $9 per kilowatt-hour, and leave them there for days.
More than two-thirds of Texas households lost power at some point that week. Pipes burst in houses never built for that kind of cold. Grocery shelves went bare. Some people genuinely burned furniture just to stay warm through the night.
The storm was already a genuine humanitarian crisis before anyone even opened their next electricity bill.
For most Texans, none of that touched their bill directly. Fixed-rate customers, the large majority of the state, kept paying whatever rate they’d already locked in, storm or no storm.
The Customers Who Felt Every Spike
A smaller group wasn’t so lucky.
Some residential plans passed the real-time wholesale price straight through to the customer, no markup, no fixed rate, just whatever the market happened to charge that hour. In calm weather, that structure could genuinely save money. During the freeze, it did the opposite.
Customers on one widely reported plan of this type saw bills climb into the thousands of dollars for a handful of days, in some documented cases reaching five figures.
The Griddy story became one of the defining consumer accounts of the storm, and it wasn’t really about one company behaving badly so much as a plan structure that worked fine right up until the exact moment it didn’t. The Texas Legislature responded within months, banning residential plans built directly on wholesale, real-time pricing.
The Real Differences Between Plan Types
That legislative response is worth understanding, because “best electricity plan” means something different depending on which of these you’re weighing:
| Plan Type | How It Prices | Weather Risk |
| Fixed-rate | Locked rate for the contract term | Stays the same regardless of grid conditions |
| Variable-rate | Rate can change monthly at the provider’s discretion | Can rise with market conditions, though within normal bounds |
| Indexed / wholesale-passthrough | Tracks the real-time wholesale market directly | Historically the most exposed to extreme price spikes (now banned for most residential accounts) |
| Prepaid | Pay in advance, balance draws down with usage | Depends on the underlying rate type; exposure varies |
Fixed-rate plans trade a bit of flexibility for predictability.
A variable-rate plan can move with the market, sometimes favorably, sometimes not, but nowhere near as violently as the wholesale-passthrough plans that made national headlines in 2021, since those are no longer sold to most residential customers in the first place.
Prepaid plans deserve a separate mention here too, mostly because they get lumped in with “risky” options they don’t always deserve to be grouped with.
A prepaid plan’s exposure to extreme pricing depends entirely on what rate structure sits underneath it. A prepaid plan built on a fixed rate carries none of the volatility that made 2021 so painful for wholesale-passthrough customers; it’s really the underlying rate type, not the prepaid billing model itself, that determines the risk.
Reading the Coverage, Not Just the Rate
None of this means “best” always equals “fixed.”
Someone with genuine flexibility to switch providers quickly, watching the market closely, has occasionally done well on a variable plan during calm stretches.
What changed after 2021 wasn’t that variable pricing disappeared; it’s that the most extreme version of it, direct wholesale exposure for residential accounts, largely got regulated out of existence for good reason.
Texas Tribune’s ongoing coverage of the storm’s aftermath documented the legislative response in detail, including the specific bill banning residential wholesale-indexed plans, one of the first pieces of storm-related legislation to reach the governor’s desk that year.
So What Does “Best” Really Mean Now
Mostly, it means matching the plan structure to how much price uncertainty someone is really willing to sit with. A household on a tight, fixed monthly budget has a very different definition of “best” than one comfortable absorbing some rate variation in exchange for potentially lower average costs over a year.
A few questions worth asking before signing anything:
- How would this plan have behaved during an extreme weather event, not just a normal month?
- Can this rate change mid-contract with just 30 days’ notice, or is it locked in for good?
- Buried in the Electricity Facts Label, what’s the worst-case price this plan could ever charge?
None of these questions require predicting the next winter storm. They just require picking a plan structure that someone can live with regardless of what any particular February decides to do.
It’s worth saying plainly that most winters in Texas pass without anything close to a repeat of 2021.
That’s exactly the point, though. A plan’s behavior in a calm, ordinary month says almost nothing about how it holds up the one time conditions turn extreme, and extreme weather is precisely when a household can least afford an unpredictable bill.
The Real Lesson From 2021
The freeze didn’t prove that Texas’s deregulated market is broken. It proved that a handful of specific plan structures carried risk most residential customers never fully understood until it cost them thousands of dollars in a single week. That gap between what a plan promised and what it could really do under stress is exactly what “best” should account for.
Deregulation itself weathered the crisis in the sense that it survived, and the legislative fixes that followed targeted the specific plan structure that failed rather than the broader idea of letting customers choose a provider. That distinction gets lost in a lot of retellings of 2021, which tend to blame “deregulation” broadly for a problem that came from one narrow corner of it.
For anyone genuinely weighing options in Texas, figuring out the best electricity plan Texas households can rely on usually comes down less to chasing the lowest number on a given day and more to understanding what that number is capable of becoming under pressure.
A slightly higher fixed rate that stays boring in February is, for most households, worth more than a lower one that occasionally isn’t.
