The Decision That Locks In Your Next 12 to 36 Months

Texas businesses approaching contract renewal face a critical decision. You can lock in certainty with a fixed rate, bet on market movement with a variable rate, or explore a third option most businesses don’t know exists. With the EIA forecasting a 45% price increase in ERCOT for 2026 after a 21% jump in 2025, the choice you make this year will impact your operating budget for the next 12 to 36 months.

The problem isn’t the math. It’s incomplete information. Most rate shopping produces sticker shock because you compare quotes without seeing what you’re comparing. Fixed rates look expensive. Variable rates look flexible. Neither reveals the full picture: when each one wins, why suppliers price them the way they do, or how market timing transforms the math.

This guide reveals what rate structure actually fits your business. You’ll see the wholesale market data behind the quotes, discover why competitors’ bills might be half yours, and know exactly when to lock in a rate versus when to stay flexible.

What Is a Fixed-Rate Electricity Plan?

Fixed rates lock the same price per kilowatt-hour for your entire contract term (typically 12, 24, or 36 months). Once you sign, your rate doesn’t change. Wholesale prices can climb, demand spikes can hit the market, but your bill stays the same.

When a provider quotes you a fixed rate, they’re not pulling that number from today’s market. They’re looking 12 to 36 months forward, estimating where wholesale prices might go, adding a risk premium to cover their uncertainty, and locking you in at that higher price.

That premium exists because suppliers have to hedge their exposure. They’re betting on market conditions. If they guess wrong and wholesale prices drop, they lose money. If they guess right and prices rise, you’ve paid for that certainty. You’re not paying for today’s electricity. You’re paying for insurance against tomorrow’s price spikes.

Fixed rates shine in one specific scenario: when you care more about predictable costs than finding the lowest price. Budget certainty lets facilities managers project annual expenses with confidence and eliminate monthly surprises.

What Is a Variable-Rate Electricity Plan?

Variable rates change monthly. No long-term contract locks you in, and switching providers takes days, not weeks. Your rate adjusts based on wholesale market conditions, and you can switch providers each month if you want to chase lower rates.

In theory, this creates optionality. In practice, it creates exposure.

When wholesale prices fall, variable rate customers benefit immediately. ERCOT’s System-wide Real-Time prices dropped from an annual average of $48/MWh in 2023 to $26/MWh in 2024. A business on a variable rate would have captured that 46% cost reduction. A business locked into a fixed rate from 2023 would have sat with regret.

But the flip side dominates the conversation once it happens. During the February 2021 Texas freeze, wholesale prices spiked to $9,000/MWh (compared to the normal $50/MWh baseline). A facility using 50,000 kWh/month with a typical $2,500 bill faced a potential $450,000 bill in that one month if rates tracked wholesale spot prices.

Variable-rate plans don’t protect you from this. They pass the volatility directly to you. For businesses with tight budgets or critical operations that can’t absorb a 10x cost increase, variable rates create structural risk. For businesses with flexible budgets and sophisticated energy management, variable rates offer upside capture when prices dip.

What Are Index or Wholesale-Rate Plans (The Third Option)?

Most businesses comparing electricity rates in Texas see two choices: fixed or variable. A third exists but rarely gets explained.

Index rates tie your per-kWh price to a specific market index. That might be PUCT electricity indices, natural gas prices, ERCOT hub-specific Locational Marginal Prices (LMPs), or other transparent benchmarks. Instead of a supplier quoting you an opaque “market rate” that adjusts monthly, you get pricing explicitly tied to a public reference.

This matters because it forces transparency. You can watch the index yourself. You see exactly how the supplier is calculating your rate. There’s no hidden markup hiding in “market adjustment” language.

Index plans sit between fixed and variable in terms of risk exposure. You still experience wholesale price volatility, but you see exactly where it’s coming from. For businesses with energy management teams sophisticated enough to monitor markets and optimize operations, index plans can be more efficient than pure variable rates because you’re not paying supplier margin on top of price volatility.

The weakness: index plans still require you to absorb price swings. You’ve traded supplier opacity for market transparency. The risk remains the same, but visibility improves.

Fixed vs. Variable at The Direct Comparison

Here’s what matters in the decision: fixed rates prioritize certainty at a cost. Variable rates prioritize flexibility with risk exposure. Neither is universally better. Both are right in different scenarios.

Fixed rates win when you operate on tight budget margins where cost surprises create problems. You value knowing your exact electricity expense for the next 24 months. You run critical operations (hospitals, data centers, manufacturing) where billing volatility creates operational headaches. You’re approaching contract renewal while forward markets are pricing electricity higher (like now, in 2025-2026). You want to stop watching the market.

Variable rates win when you have budget flexibility to absorb monthly rate changes. You want to chase potential savings when wholesale prices drop. You’re willing to actively switch providers to capture better rates. You can operate profitably even if electricity costs spike 10-15% in a given month. You want maximum contractual flexibility.

The math works differently depending on your risk tolerance. A healthcare facility protecting against supply-chain disruption should lock fixed rates despite the premium. A small retail operation with variable demand and flexible budgeting might capture more savings on variable rates by switching during shoulder seasons.

But there’s a timing layer most businesses miss.

Why Contract Timing Changes Everything

Texas electricity rates follow a seasonal rhythm driven by cooling demand. Summer months (June through August) see the highest electricity demand as air conditioning systems work at full capacity. Spring and fall shoulder seasons (February through May, September through November) experience lower demand and lower rates.

Spring rates average 8 to 12 cents per kilowatt-hour. Summer rates climb to 15 to 20 cents per kilowatt-hour or higher. Peak summer usage runs more than 50% higher than cool spring periods. A facility that renews a contract in spring locks in rates for a year when demand patterns are low. That same facility renewing in summer locks in rates that reflect peak demand spikes.

If your current contract ends in July (peak summer), you have options. Option one: sign a fixed-rate contract during summer highs, locking in expensive rates for the next 12-36 months. Option two: sign a short-term variable plan through September, then renegotiate in October when shoulder season rates have already begun falling.

Most REPs allow rate locks 60 to 90 days before your contract actually expires. This window is your leverage point. If you plan ahead, you can shift your renewal window.

For 2025-2026 specifically, timing carries extra weight. ERCOT forward contracts are trading above $50/MWh for calendar years 2025 through 2028. Summer on-peak months are pricing in at $110 to $165/MWh in some hubs, compared to August 2024 averages in the mid-$40s/MWh. If you lock now during shoulder season, you capture lower rates before the summer peak hits.

How Demand Charges Complicate the Decision

Most businesses overlook the fact that their electricity bill has two separate components: supply charges and demand charges.

Supply charges are what you’ve been reading so far: fixed or variable rates based on your total kilowatt-hour consumption. A facility using 100,000 kWh at a variable rate of 12 cents per kWh pays $12,000 for supply.

Demand charges are different. They’re based on the maximum amount of power (measured in kilowatts) that you draw during any single interval (typically 15 minutes) during the billing period, multiplied by the demand charge rate ($/kW).

Picture it this way: imagine you run 30 kW of power continuously all day. Your peak 15-minute interval might spike to 35 kW because of an equipment startup. That 35 kW peak becomes your billable demand for the entire month, and you pay the demand charge rate applied to 35 kW, not 30 kW.

This matters because demand charges apply regardless of whether your supply rate is fixed or variable. You’ve focused on choosing a rate structure for supply. You have zero control over whether demand charges go on top of that structure.

If you lock in an attractive fixed supply rate but ignore demand charges, your bill surprises will come from the demand component, not the supply component. A facility with poor load management that spikes to 40 kW during startup could be paying demand charges on 40 kW all month even though average usage is 28 kW.

When evaluating fixed versus variable, recognize that both choices sit on top of pass-through demand charges. Your rate type decision and your demand optimization are separate problems.

Hybrid and Blended Rate Structures

Some businesses split the difference. A common structure locks 70% of expected usage at a fixed rate and lets 30% float on index rates. This approach balances budget certainty with savings upside.

If a facility averages 100,000 kWh per month, they might fix 70,000 kWh at a locked rate and let 30,000 kWh trade on an index rate. During months when wholesale prices drop, the 30,000 kWh portion captures savings. During months when prices spike, only 30% of the bill experiences the shock. The fixed 70% provides a cost floor.

This requires active contract management. You need to calculate your actual baseline usage accurately, establish how contract true-ups work if you exceed the fixed block, and review the split at each renewal to adjust based on actual demand patterns.

Load-following blocks offer another variation: instead of a fixed percentage, you might set the fixed block to match your consistent baseline load (the power you draw every hour regardless of season) and let usage above that baseline float on variable rates. This more precisely matches your rate structure to your actual consumption pattern.

Hybrid structures work best for facilities with sophisticated energy management teams. They require ongoing monitoring and willingness to actively manage the contract. For businesses preferring simplicity, pure fixed or variable is cleaner.

Market Conditions in 2025-2026 and Why They Matter Now

Wholesale electricity prices in ERCOT are projected to rise 45% in 2026 after climbing 21% in 2025. Forward contracts for 2025 through 2028 are trading above $50/MWh overall. Summer on-peak months reach $110 to $165/MWh in some hubs. These are actual market prices that suppliers are using right now to calculate the fixed-rate quotes they’re sending you.

What’s driving this? Electricity demand in ERCOT is expected to grow at 11% annually in 2025 and 2026, driven primarily by data center and cryptocurrency mining facility additions. ERCOT is adding 26.8 GW of new capacity in 2025 (12.3 GW of solar and 11.8 GW of energy storage), but demand growth is outpacing supply additions. That supply-demand gap is structural.

S&P Global energy research forecasts that high temperatures and strong natural gas costs could push August 2025 prices to triple digits, compared to August 2024 averages in the mid-$40s/MWh. The data center boom isn’t slowing down. Supply additions help but don’t fully close the gap.

This market context creates a window. If you’re shopping for contracts now during shoulder season prices before the summer peak, you’re locking in rates before the market fully prices in 2026’s expected 45% increase. If you wait until summer to renew, suppliers will be quoting you fixed rates that already reflect that full increase.

For fixed-rate customers, the math is clearer. Certainty becomes more valuable when prices are expected to rise significantly. For variable-rate customers, the message is stark: these are not years to ride variable rates blindly.

Real Business Scenarios at When Each Rate Type Wins

A healthcare facility running 24/7 operations with stable load usage faced exactly this decision in 2024. Their facility consumes roughly 80,000 kWh per month. They locked in a fixed-rate plan through 2024, protecting against wholesale volatility. When the February 2021 Texas freeze spiked wholesale prices to $9,000/MWh, their fixed rate protected them. Variable-rate customers on similar profiles faced bills in the thousands or millions of dollars in that single month. The healthcare facility’s fixed-rate premium suddenly looked like a bargain.

Compare that to a small retail operation with highly seasonal demand and flexible cost structure. Peak summer demand runs 30% higher than spring baseline. This retail owner switched providers in May 2024 (spring shoulder season) to a variable rate at 10.2 cents per kWh. In September 2024, rates had fallen to 9.8 cents per kWh, so they switched again. In March 2025, rates were back around 10 cents/kWh. Over 12 months, their blended cost was lower than fixed-rate quotes for the same period because their high flexibility let them chase shoulder season rates.

A large commercial campus with stable load benefits from fixed rates despite premium pricing. Demand spikes only occur during peak cooling or heating seasons. The facility’s core load is predictable. Fixed rates eliminate the burden of monthly rate monitoring and let the operations team focus on efficiency.

A data center with sophisticated energy management and a dedicated efficiency team can benefit from index/wholesale rates. They monitor ERCOT pricing daily, optimize workload timing to run during lower-price windows, and adjust consumption patterns based on market signals. Their team has capacity to actively manage pricing risk. Index rates give them transparency into wholesale moves.

A commercial customer facing 2025-2026 contract renewal encounters sticker shock immediately. Wholesale prices have more than doubled over the last 48 months. But this sticker shock is exactly why fixed-rate locking looks attractive despite premium pricing. The market is telegraphing sustained elevation. Locking now captures the low end of the expected range.

A facility splitting load 70% fixed / 30% variable achieves balance. Their 70% block provides budget certainty on core costs. The 30% variable portion captures savings during low-price windows (spring, fall, solar-heavy days) while limiting exposure to spikes.

Decision Framework at How to Choose

Start with your budget constraint. Can you absorb a 20% increase in your monthly electricity bill without operational impact? If no, you’re a fixed-rate candidate regardless of market outlook. If yes, you can entertain variable or hybrid options.

Next, assess usage stability. Facilities with stable load (24/7 operations, consistent process demand) favor fixed rates because you can accurately predict your annual cost. Facilities with seasonal or variable demand have more flexibility to time contract renewals and can potentially capture savings on variable rates by switching during shoulder seasons.

Then evaluate your organizational capacity. Do you have a facilities manager or energy team with bandwidth to monitor electricity markets and switch contracts actively? If yes, variable or index rates unlock value. If no, fixed rates simplify your life.

Calculate your risk tolerance in dollar terms. A 50,000 kWh facility at $0.12/kWh pays $6,000 monthly. If rates spike 50%, that’s a $3,000 increase. Can you absorb that as an operations team?

Look at historical rates for your facility over 12-24 months. What’s your seasonal pattern? When do peaks and valleys occur? If your contract is ending in July, can you negotiate a renewal in May or shift to a short-term plan? Timing alone can save 5-15% depending on market conditions.

Get quotes for both fixed and variable structures. Compare the all-in cost: not just the per-kWh rate, but the demand charges, any minimum charges, and early termination fees. Our business electricity contract guide breaks down every line item. Many businesses compare only the base rate and miss the true cost of switching.

Finally, consider this year’s market context. Prices are rising. Forward markets expect continued elevation through 2028. Locking fixed rates now captures value that won’t exist in six months. But if your facility works best on variable rates, recognizing the risk (triple-digit wholesale prices are possible during peak demand) lets you make that choice with eyes open.

Frequently Asked Questions

The Bottom Line

Fixed and variable electricity rates serve different needs. Fixed rates provide certainty and budget predictability by locking rates for 12-36 months. Variable rates offer flexibility and potential savings by adjusting monthly with wholesale markets. Neither is universally better. Both are right in different scenarios.

The decision hinges on three questions: How much budget flexibility does your business have? How stable is your usage? Do you have the organizational capacity to actively manage electricity contracts?

But there’s a timing layer that will matter more in 2025 than it will in 2026. Wholesale prices are rising. Forward markets expect sustained elevation. If fixed-rate certainty aligns with your needs, locking now during shoulder season (before summer demand hits) captures value you won’t see later in the year. If variable rates work for your profile, recognizing the real risks (triple-digit wholesale spikes are possible) lets you make that choice with clarity.

The Benchmarks Your Provider Will Never Share

The Texas commercial electricity average is 9.12 cents/kWh for the energy-only portion. If your rate is below that, you are ahead of the majority. If your rate is at 6 cents or below, you are in the top tier of Texas commercial accounts. But “good” depends on three variables that generic rate comparisons ignore: how much electricity your business uses per month, which TDU territory your meter sits in, and whether the number you are comparing is the energy-only rate or the all-in cost that includes delivery charges.

Most business owners compare the wrong number. They look at their total bill, divide by kWh, and compare that blended rate to the energy-only rate advertised by providers. That comparison always makes your current plan look expensive and the advertised plan look cheap. Here is how to benchmark your commercial electricity rate against what Texas businesses actually pay, broken down by the factors that determine whether your rate is competitive.

Where Your Business Falls

Texas commercial electricity rates cluster into three tiers based on monthly consumption. Your tier determines what “good” looks like.

Small commercial (under 50,000 kWh/year or roughly under 4,200 kWh/month): Energy-only rates for this tier run 8 to 11 cents/kWh. A good rate is anything below 9 cents. An excellent rate is below 7.5 cents. This tier pays the highest per-kWh energy rates because providers build more margin into plans for smaller accounts. The fixed costs of servicing an account are roughly the same whether that account uses 3,000 kWh or 30,000 kWh per month, so the per-unit overhead on small accounts runs 2 to 3x higher.

Mid-market commercial (50,000 to 500,000 kWh/year or roughly 4,200 to 42,000 kWh/month): Energy-only rates for this tier run 6 to 8 cents/kWh. A good rate is below 7 cents. An excellent rate is below 6 cents. This is the tier where rate shopping delivers the largest absolute dollar savings. A 1-cent/kWh improvement on 20,000 kWh/month saves $200/month or $4,800 over a 24-month contract.

Large commercial (over 500,000 kWh/year or over 42,000 kWh/month): Energy-only rates for this tier run 4.5 to 6.5 cents/kWh. A good rate is below 5.5 cents. An excellent rate is below 5 cents. At this volume, businesses typically work with brokers or negotiate directly with retail electricity providers. Custom pricing replaces published rate plans, and the purchasing power from high volume pushes rates well below what small and mid-market accounts can access.

These tiers are not arbitrary. They reflect the economic reality of how Texas retail electricity providers price commercial accounts. Higher volume means lower per-unit costs for the provider, which translates to lower rates for the customer.

Energy-Only vs. All-In and the Comparison Most Business Owners Get Wrong

The single biggest source of confusion in commercial electricity pricing is the difference between the energy-only rate and the all-in cost per kWh. Every advertised rate, every provider quote, and every “low rate” claim refers to the energy-only portion. Your actual cost per kWh is 40 to 60% higher than that number.

Your total electricity bill has two main components. The energy charge comes from your retail provider and reflects the per-kWh rate you shopped for. The delivery charge comes from your TDU (Oncor, CenterPoint, AEP Texas, or TNMP) and covers transmission and distribution of electricity to your meter. The delivery charge is identical regardless of which provider you choose. It is regulated by the Public Utility Commission of Texas and passed through dollar for dollar.

When delivery charges are included, the all-in cost for Texas commercial electricity typically runs 11 to 15 cents/kWh. If your energy-only rate is 7 cents/kWh, your all-in cost is probably 11 to 13 cents/kWh depending on your TDU and rate class.

Here is the comparison that matters: pull your total bill, divide by total kWh consumed, and that is your all-in rate. Then compare that number to these all-in benchmarks by tier.

Small commercial all-in: 12 to 16 cents/kWh. Good is below 14 cents. Mid-market all-in: 10 to 13 cents/kWh. Good is below 12 cents. Large commercial all-in: 8 to 11 cents/kWh. Good is below 10 cents.

If your all-in rate falls within the “good” range for your tier, your plan is competitive. Switching providers changes only the energy portion, not the delivery portion, so the potential savings from switching are limited to the 50 to 60% of your bill that represents the energy charge.

How Your TDU Territory Affects What “Good” Means

Texas has five TDU territories, and each one charges different delivery rates. Two businesses with identical energy-only rates can have all-in costs that differ by 1 to 3 cents/kWh purely because of their TDU assignment.

Oncor (Dallas-Fort Worth, much of North Texas): Oncor delivery charges are moderate, making all-in costs roughly 3 to 5 cents above the energy rate. Oncor serves the largest number of commercial accounts in Texas and offers the widest selection of competing providers after CenterPoint.

CenterPoint (Houston metro): CenterPoint delivery charges run slightly higher than Oncor. Houston businesses should expect all-in costs 3.5 to 5.5 cents above their energy rate. The tradeoff is that CenterPoint territory has the deepest pool of competing providers in the state, which drives energy-only rates lower.

AEP Texas (South Texas, West Texas, Corpus Christi): AEP delivery charges vary more by rate class but are generally comparable to CenterPoint. Businesses in AEP territory often have fewer provider options, which can push energy-only rates 0.5 to 1 cent higher than DFW or Houston.

TNMP (scattered areas across Texas): TNMP territory includes parts of Central Texas and the Gulf Coast. Delivery charges are competitive with Oncor in most rate classes.

Lubbock Power & Light: Lubbock operates its own municipal utility and is not part of the deregulated ERCOT market. Lubbock businesses cannot choose their electricity provider and pay rates set by the city utility.

Your TDU territory is determined by your physical location. You cannot change it. But knowing your TDU’s delivery charge structure helps you calculate whether a lower energy rate from a new provider actually reduces your all-in cost enough to justify the switch.

When Contract Timing Determines Whether Your Rate Is “Good”

The same energy rate can be excellent or mediocre depending on when you locked it in. Texas commercial electricity rates fluctuate based on natural gas prices, ERCOT wholesale market conditions, seasonal demand, and forward price expectations.

Rates locked during winter months (November through February) have historically been 10 to 20% lower than rates locked during summer months (June through August). This is not a rule. It is a pattern driven by the fact that summer demand tightens ERCOT supply margins, which pushes forward prices higher. Providers price summer risk into every contract offered between May and September.

If you locked a 24-month contract at 7 cents/kWh during March 2025, that was a competitive rate at the time. If the market has since dropped to 5.5 cents/kWh for similar terms, your rate is no longer “good” by current standards, but you are locked in and should not pay an early termination fee to chase a marginally better rate. The math rarely works out.

The honest assessment: a rate locked 12+ months ago may look expensive compared to today’s market. That does not mean you made a bad decision. It means the market moved. The question is whether the gap between your rate and the current market justifies an early termination fee and a new contract.

For most businesses, the answer is no unless the gap exceeds 2 cents/kWh and you have more than 12 months remaining on your current term. At 2 cents/kWh on 10,000 kWh/month, you save $200/month. If your early termination fee is $1,500 and you have 18 months left, you save $3,600 minus $1,500, netting $2,100. That math works. At 0.5 cents/kWh, the same calculation nets $400 over the remaining term. That does not justify the hassle.

What the National Average Tells You (and What It Hides)

The U.S. average commercial electricity rate is approximately 14.12 cents/kWh. The Texas average is 9.12 cents/kWh. Texas commercial rates run roughly 35% below the national average.

This gap exists because Texas operates its own deregulated wholesale market (ERCOT), has abundant natural gas supply, massive wind generation capacity, and growing solar capacity. The combination of competition among retail providers and low-cost generation sources keeps Texas commercial rates well below states like California (22 to 28 cents/kWh), New York (18 to 24 cents/kWh), and Connecticut (20 to 26 cents/kWh).

But the national average is not a useful benchmark for Texas businesses. Comparing your Texas rate to the national average creates a false sense of comfort. You are not competing against California businesses for electricity costs. You are competing against the other Texas business on your block that may be paying 2 to 3 cents/kWh less for the same commodity.

The relevant comparison is always within Texas, within your TDU territory, and within your usage tier. A 9-cent rate looks great next to the national average. It looks less impressive when the best available rate for your usage level is 5.5 cents in the same territory.

How to Determine If Your Current Rate Is Actually Good

Five steps. Ten minutes. No provider calls required.

Step 1: Find your energy-only rate. Look at the energy charges section of your bill. Divide total energy charges by total kWh. This is your effective energy rate. Ignore any “average price per kWh” that includes delivery, as that is your all-in rate, not the number you compare to advertised plans.

Step 2: Identify your usage tier. Add up your annual kWh consumption from the last 12 bills. Under 50,000 kWh/year is small commercial. 50,000 to 500,000 is mid-market. Over 500,000 is large commercial.

Step 3: Compare to your tier benchmark. Is your energy-only rate below the “good” threshold for your tier? If yes, your rate is competitive. If your rate exceeds the tier average, the gap between your rate and the benchmark represents your potential savings per kWh.

Step 4: Calculate the dollar impact. Multiply the gap between your rate and the benchmark by your monthly kWh. Then multiply by your remaining contract months. This is the total cost of staying at your current rate versus what a competitive plan would cost.

Step 5: Check your contract end date. If your contract expires within 60 to 90 days, comparing new plans now captures current market pricing. If expiration is 6+ months away, set a calendar reminder for 90 days before renewal.

The Bottom Line on What Constitutes a Good Rate

A “good” Texas commercial electricity rate is below 9 cents/kWh energy-only for small businesses, below 7 cents for mid-market, and below 5.5 cents for large commercial accounts. But the number that determines your actual electricity cost is the all-in rate, which runs 3 to 6 cents/kWh higher than the energy-only rate depending on your TDU territory.

If your energy rate is competitive for your tier and your contract timing was reasonable, you are paying what the market supports. If your rate exceeds your tier benchmark by more than 1.5 cents/kWh and your contract is expiring soon, the savings from switching are real and quantifiable.
