Texas Winter Electricity Rates: What to Expect

November is the cheapest month to lock a Texas electricity contract.

Most Texans never notice. They re-shop when their contract expires, whenever that happens to be. Whether they accidentally hit a good window or get stuck with summer pricing depends on luck.

You can do better than luck. The winter rate floor is reliable, the timing window is clear, and the difference between a November lock and an August lock can be $200-$400 over a 12-month contract.

Here's how Texas electricity prices behave in winter, and how to use the pattern.

Why November is the floor

Wholesale electricity prices in Texas track demand. Demand tracks weather. In November, three things are simultaneously true:

• Summer cooling demand is over. Wholesale prices have come off their seasonal peak.
• Winter heating demand hasn't kicked in yet. Most Texas homes don't fire up significant electric heat until December.
• Reserve margins are loose. Generation that was running flat-out in August is mostly available; capacity is abundant.

REPs hedge forward, which means the contract rates they offer in November reflect November's wholesale floor. They're not pricing in much weather risk, because the months immediately ahead (late November, early December) are typically mild.

By late January, the calculus shifts. Cold-weather events start to price in. By March-April, wholesale prices begin pricing in summer demand. By July-August, contract pricing reflects the most volatile months of the year being right around the corner.

The same plan from the same REP often prices 0.5-1.5¢/kWh cheaper in November than in July. On 12,000 annual kWh, that's $60-180/year for the same product.

How big a deal is the winter rate gap?

Comparing fixed-rate plans signed in different months:

• November 2024 signing, 12-month plan at 9.8¢/kWh: $1,176 annual energy charge on 12,000 kWh
• August 2024 signing, same plan now at 11.4¢/kWh: $1,368 annual energy charge

The same plan, same provider, same household — $192/year difference based on timing alone.

Multiply by a 24-month contract and the gap widens further. The market doesn't reset every month; you're locked into November's pricing or August's pricing for the full term.

If your current contract is expiring in August, the right move is often to bridge with a short-term plan (month-to-month or 6-month) until November, then lock the long-term plan at the seasonal floor. Calculate carefully — the bridge plan's higher monthly rate has to be less than the difference between August and November pricing on your 12-24 month plan.

Winter usage patterns: smaller, not small

A typical Texas home uses 800-1,200 kWh in December-February — about 30-40% of August usage. Bills are lower, but not negligible.

Where winter usage comes from:

• Heat pumps and electric heat strips. Modern heat pumps are efficient (3-4× the heat output per kWh of input). Strip heat (the backup or supplemental electric heating in many homes) is 1:1 — expensive.
• Hot water heaters. Electric water heaters work harder when incoming water is colder. December-February water heating uses 20-30% more electricity than May-September.
• Lighting. Days are shorter. Lighting load increases ~15%.
• Cold-snap AC reversal. A 35°F morning followed by an 80°F afternoon makes the AC work hard for a few hours. Texas weather doesn't stop.

A 900 kWh January bill on a 10¢/kWh plan is $90 in energy charges plus TDU pass-through ($45) plus base charges ($5-10) = $140-145 total. Not huge, but real.

Cold snaps and what they do to rates

The big risk in Texas winter isn't average prices — it's tail events. Winter Storm Uri (February 2021) drove wholesale prices to $9,000/MWh for several days. Storms in January 2024 and January 2026 caused short-duration spikes too.

Fixed-rate customers were insulated during all three events. The rate they were paying was locked.

Variable-rate customers got crushed. Indexed-plan customers got destroyed.

The lesson, repeated: fixed-rate is non-negotiable for residential customers. The winter-event risk is the strongest argument against variable pricing, even when variable rates are nominally lower in mild years.

The PUCT after Uri added rules that limit how much wholesale spikes can flow to residential customers on most products, but the "most" qualifier matters. A few indexed-pricing products still pass wholesale risk to customers. Always check the plan structure on the EFL.

Heat-pump homes need different math

Texas has a growing population of all-electric heat-pump homes. For these households, winter electricity usage can match or exceed summer usage.

A 2,000 sq ft heat-pump home in Houston might use:

• May-September: 1,800-2,400 kWh/month (heavy AC)
• December-February: 1,500-2,200 kWh/month (heavy heating)
• October-November / March-April: 800-1,100 kWh/month (mild)

For these households, winter rate locks are even more important. The winter usage is large enough that a poorly-timed contract eats real money during heating months.

If you're a heat-pump household, shop your plan for whole-year usage, not for one season. A bill-credit plan optimized for 1,000-1,999 kWh works for you 5-6 months a year and fails during peak summer and peak winter. The math changes.

Cold-weather disconnect protections

A piece of Texas regulation worth knowing: REPs can't disconnect residential customers for non-payment when temperatures are forecast to drop below 32°F or rise above 100°F in the next 24 hours. The rule applies year-round but matters most in extreme weather.

This isn't a license to skip bills — back charges accumulate, and disconnections happen the moment the weather window closes. But it does mean a single bad month during a cold snap doesn't immediately mean lights out.

The full PUCT rule includes payment plan provisions, deferred payment options, and emergency assistance referrals. For households in financial difficulty during winter, the protections are real but require knowing they exist.

Locking strategy: 12-month vs. 24-month

If you're shopping in November:

• 12-month fixed. Locks the winter rate floor for a year. Re-shop next November. Lowest commitment, requires repeating the exercise annually.
• 24-month fixed. Locks for two years at typically 0.5-1.0¢/kWh lower than the 12-month equivalent. Maximum savings if you're settled. ETF if you move.

For settled households with stable usage, 24-month wins. For renters with shorter horizons, 12-month is the standard.

For households who lock in summer or other "wrong" months, consider:

• 6-month plans as bridges. Most REPs offer them at slight rate premium. Useful for getting from a bad lock window to November.
• Month-to-month variable as a 2-3 month bridge. Higher rate per month but no commitment. Only viable if November is close.

When to stay on your current plan

The November-locking advice assumes you're due to shop. If you're already on a good fixed-rate contract that doesn't expire until next August, don't break it.

The early termination fee ($150-$295) almost always exceeds the savings from re-shopping mid-contract — unless rates have moved dramatically. Calculate before you switch: monthly savings × remaining months vs. ETF.

For most households mid-contract, the right action in November is schedule the re-shop for next year, not actually switch this year.

The honest close

Winter rates in Texas are a structural pattern. Wholesale prices drop after summer demand ends; REP contract pricing follows. November is consistently the cheapest month to lock; late summer is consistently the most expensive.

The savings are real but small per month — about $15-25/month over a year for a typical household. They add up to a 12-month plan that's $180-300 cheaper at the seasonal floor than at the seasonal peak.

The cost of using this knowledge: 30 minutes of shopping in early November. The payback is automatic.
