The $960 mistake most Texans make
Sign up for lights in July when rates are high, and you lock in 18 cents per unit for 12 months. Wait until April when rates drop to 10 cents, and you pay 44% less for the exact same power.
For a typical home using 1,000 units per month, that is $80/month or $960/year in savings just by knowing when to shop. This guide shows you the pattern so you never overpay again.
Why Texas Light Rates Follow Seasons
Texas runs on its own power grid (ERCOT), and prices move with demand. When everyone cranks their AC in July, demand spikes and wholesale power costs jump. Light companies know this, so they raise retail rates to cover their risk.
When the weather is mild in April or October, demand drops. Power is cheaper to generate, and light companies compete harder for customers. Rates fall 30-50% compared to peak summer months.
The pattern repeats every year. Once you see it, you can time your switching to lock in the lowest rates and ride them out through the expensive months.
The Four Seasons of Texas Light Rates
Five Years of Data: The Pattern Holds
From 2021 through 2026, Texas light rates followed the same seasonal cycle. Summer peaks. Spring dips. Fall offers a second window. Winter fluctuates based on cold weather.
Historical Rate Ranges (2021-2026)
What changed from 2021 to 2026: Overall rates increased due to inflation, natural gas prices, and grid infrastructure costs. In 2021, spring rates averaged 7-9 cents. By 2026, that range shifted to 8-12 cents. But the seasonal pattern stayed the same.
The key insight: Even as absolute prices rise, the seasonal spread remains consistent. Summer rates are still 50-100% higher than spring rates. That gap is your opportunity to save.
Exception: Winter Storm Events
During extreme cold snaps like Winter Storm Uri (February 2021), wholesale prices spiked to historic levels. If you were on a variable-rate plan during Uri, your bill could have been 10-20x normal. This is why we recommend fixed-rate plans locked during low-rate seasons—you are protected when chaos hits.
How ERCOT Demand Drives Your Light Bill
ERCOT (Electric Reliability Council of Texas) manages the Texas power grid. When demand is high, power plants have to fire up expensive backup generators. Wholesale prices spike. Light companies pass those costs to you.
Summer Peak Demand
85,500 MW
Record summer peak (2023)
Peak hours: 3-7 PM when AC usage maxes out across the state. Wholesale prices during these hours can jump 300-500% above off-peak rates.
Winter Peak Demand
78,138 MW
Record winter peak (January 2025)
Winter demand is growing faster than summer. ERCOT projects winter peaks may surpass summer before 2050 as more Texans use electric heating.
Why spring and fall are cheap: Demand drops to 50,000-60,000 MW during mild weather. Power plants run at lower capacity. Wholesale prices fall to $20-40 per megawatt-hour (MWh) instead of $100+ during peak months. Light companies lock in these low wholesale rates and offer competitive retail rates to attract customers.
Wind generation impact: Texas generates significant wind power, especially at night and during windy seasons. When wind is strong, wholesale prices drop further because wind energy is essentially free once turbines are built. This amplifies the spring and fall advantage—wind is often strongest during these shoulder seasons.
Demand Pattern Breakdown
Shopping for lights? Check all your options first.
Seasonal rates matter for traditional plans. But if you need lights without a deposit, we can help you find options beyond prepaid. We check multiple light companies to see if you qualify for $0 deposit on a traditional plan (8-13¢/kWh, subject to seasonal rates). Many people find at least one option. Can't promise it'll work, but worth checking. If no traditional option works, prepaid lights are always available — $40-75 to start, flat rate year-round (no seasonal spikes).
Your Switching Strategy: Lock Low, Ride High
The goal is simple: lock in a fixed-rate contract during low-rate months, then ride that rate through the expensive months. Here is how to execute it.
Target Your Shopping Window
Best months to shop: April, May, October, November
These months offer the lowest rates and highest competition among light companies. If your contract expires in these months, you are in luck. If not, plan ahead.
Use the 14-Day Rule
Texas law lets you switch light companies during the final 14 days of your contract without paying early termination fees. Mark your calendar 60-90 days before your contract ends, start watching rates, then lock in during your final 14 days when you find a good deal.
Pick the Right Contract Length
If you lock in during April at 10 cents per unit, choose a 12-month contract. This carries you through expensive summer (June-August) and brings your renewal back to April 2027—another low-rate window.
Advanced move: If your contract expires in July (bad timing), consider a short 8-10 month contract to shift your next renewal into spring. You might pay slightly higher rates for those months, but you set yourself up for better timing long-term.
Avoid Peak Shopping Months
Worst months to shop: July, August, January, February
If your contract expires during peak months, you have two options: (1) Pay the early termination fee to switch early during a low-rate window, or (2) Ride out a month-to-month variable rate until the next shoulder season, then lock in.
What If You Need Lights Right Now?
If you are in crisis mode—lights already off, moving this week, no deposit money—timing does not matter. Get connected with whatever is available (usually prepaid or no-deposit plans).
Once your lights are on and you are stable, watch for the next low-rate window (spring or fall) to switch to a better plan. Prepaid plans have no contracts, so you can switch anytime without fees.
Timing Strategy for Prepaid Lights
Prepaid plans work differently. You are not locked into a contract, so you can switch anytime without penalties. This gives you flexibility traditional plans do not have.
Prepaid Advantages
- + Switch anytime—no early termination fees
- + No contract means you can jump on seasonal rate drops immediately
- + Get connected fast during crisis, optimize timing later
Prepaid Limitations
- - Base rates are typically 30-50% higher than traditional plans
- - Seasonal rate drops are smaller because you start from a higher baseline
- - Switching requires proactive monitoring—no one reminds you
Best strategy for prepaid: Use prepaid to get your lights on when you need them, regardless of season. Once you are stable, set calendar reminders for April and October. Check rates during those months and switch to a better prepaid plan if available. Or, if your credit has improved, use those low-rate windows to transition to traditional plans.
Prepaid Switching Checklist
What is Coming: 2026-2027 Rate Forecast
Overall rates are trending up. Here is what is driving the increase and when you should act.
2026-2027 Forecast Summary
Key drivers pushing rates higher: Natural gas prices are rising due to increased LNG exports. ERCOT demand is surging from new data centers and cryptocurrency operations. Grid infrastructure costs are climbing as Texas adds capacity to prevent blackouts.
What this means for you: Even though overall rates are rising, the seasonal pattern will persist. Spring 2026 rates (April-May) will still be significantly cheaper than summer 2026 rates (July-August). The savings gap may actually widen as volatile summer demand pushes peak prices even higher.
Action Plan for 2026-2027
- → February-March 2026: Wait if possible. Rates should drop in April.
- → April-May 2026: Prime window. Lock in a 12-month fixed rate to protect against summer spikes.
- → June-September 2026: Avoid shopping unless urgent. Ride out your locked rate.
- → October-November 2026: Second window. If you missed spring, lock now before winter.

The Bottom Line
Texas light rates follow a predictable seasonal pattern. Spring (April-May) and fall (October-November) offer the lowest rates. Summer (July-August) and winter extremes (January-February) push rates to their peaks.
By timing your shopping and contract renewals to low-rate windows, you can save $300-500 per year compared to someone who shops randomly or renews during peak months.
If you are on prepaid or have no contract, use your flexibility. Set alerts for April and October, check rates, and switch when you find better deals. If you are on a traditional contract, use the 14-day rule to switch penalty-free at the end of your term. Plan your contract length to land renewals in shoulder seasons.
