How to Compare Commercial Electricity Rates in Texas
To compare commercial electricity rates accurately in Texas, every quote has to be normalized to the same load profile, TDU territory, term, and price structure. The five-line worksheet, seven hidden line items, and six common errors that move a comparison from headline-cheaper to actually-cheaper.
To compare commercial electricity rates accurately in Texas, every quote has to be normalized to the same load profile, the same Transmission and Distribution Utility (TDU) territory, the same contract term, and the same all-in price structure. Most buyers shop the headline cents-per-kWh number, miss the base charges and tiered pricing buried in the Electricity Facts Label (EFL), and end up paying 1 to 2 cents per kWh above what a normalized commercial electricity comparison would have produced.
This article walks through the five-line apples-to-apples comparison worksheet that consultants use, the seven hidden line items that have to be unified across quotes, and the six common errors that turn a "cheaper" headline into a more expensive bill. To compare commercial electricity rates Texas businesses are quoted, the worksheet below is the standard tool. For broader context, see the pillar guide on commercial electricity rates in Texas and the electricity rate comparison Texas ERCOT methodology.
Why a Headline Comparison Fails When Buyers Compare Commercial Electricity Rates
When buyers compare commercial electricity rates by headline alone, they miss most of the bill. A 6-cent fixed-rate energy quote in CenterPoint and a 7-cent fixed-rate quote in Oncor are not comparable. Different territories have different delivery tariffs. Different REPs structure base charges and minimum-usage penalties differently. Different EFLs price three different usage tiers (commonly 5,000, 10,000, and 25,000 kWh per month for commercial). A buyer comparing only the energy line is comparing apples to four-fruit smoothies.
The PUCT requires every REP to publish an EFL under Substantive Rule 25.475 and Rule 25.475(c) (formerly 25.37). The EFL is normalized in format but not in load profile. Two REPs can both produce compliant EFLs that look like 6.5 cents per kWh and 7.0 cents per kWh, while the all-in commercial bill for the same load runs $11,200 per year on the first quote and $10,800 on the second. To compare commercial electricity rates correctly requires backing out every line item to the same usage and territory.
The Five-Line Commercial Electricity Comparison Worksheet to Compare Commercial Electricity Rates Texas Buyers Run
Every quote reduces to five lines. Build the worksheet once, run every EFL through it, compare the all-in number.
| Line | Component | Source |
|---|---|---|
| 1 | Energy charge (energy rate x kWh) | EFL energy rate at customer's specific usage tier |
| 2 | Demand charge ($ per kW x peak kW) | TDU tariff for demand-metered accounts; REP if bundled |
| 3 | TDU delivery (fixed customer charge + per-kWh distribution + per-kW transmission) | Pull from the customer's TDU tariff at puc.texas.gov |
| 4 | Base, minimum-usage, and regulatory pass-through fees | EFL base charge, minimum penalty, REP fee schedule |
| 5 | Taxes (state sales tax, gross receipts, ERCOT pass-through fees) | Approximately 6-10% of subtotal |
All-in cents per kWh = Total annual cost / Total annual kWh.
For a 5,000 kWh per month / 50 kW peak commercial load on Oncor, a typical worksheet on a 12-month fixed plan at 6.72 cents per kWh on the energy line:
| Line | Annual amount |
|---|---|
| 1: Energy (6.72 cents x 60,000 kWh) | $4,032 |
| 2: Demand ($6/kW x 50 kW x 12 mo) | $3,600 |
| 3: TDU delivery (3.2 cents/kWh + $10/mo customer + $8/kW transmission) | $4,800 |
| 4: Base + min-usage + regulatory ($10/mo base) | $120 |
| 5: Taxes (8% of $12,552 subtotal) | $1,004 |
| Total annual | $13,556 |
| All-in cents per kWh | 22.6 cents (small commercial) or 9.0 cents if energy-only basis |
Wait, that does not match what most buyers expect. Two issues to flag for the worksheet user.
First: the "9.0 cent all-in" figure most consultants cite is the energy line plus delivery only, divided by kWh. That number lines up with the EIA's 8.6 cents commercial average but ignores demand charges. On a demand-metered account, the demand component frequently runs 30-50% of the bill and shows up only on Line 2. Always run the worksheet two ways: energy-only-plus-delivery, and full-bill-divided-by-kWh.
Second: for sub-50 kW small commercial customers, Line 2 disappears entirely. The all-in becomes Lines 1+3+4+5, which produces a much cleaner 8.5-11 cents per kWh result. The worksheet structure is the same, but the components shift.
Seven Hidden Line Items to Unify
The line items that move a commercial electricity comparison from "headline cheaper" to "actually cheaper" are buried in the EFL and the TDU tariff. Pull each one and unify.
1. Base Charge
The fixed monthly fee, separate from kWh consumption. Typical commercial range: $5 to $20 per month. A "low-rate" plan with a $25 base charge can cost more annually than a higher-rate plan with no base.
2. Minimum Usage Fee
Triggers if monthly kWh falls below a threshold (commonly 500-2,000 kWh for small commercial). Range: $0 to $50 per month. Critical for seasonal businesses, vacation rentals, or companies with multiple locations including some small ones.
3. Tiered Pricing
The headline rate often applies only at a specific usage tier. A 9.3 cents per kWh plan might apply only at 1,000-1,999 kWh; usage at 875 kWh could trigger a 22.3 cents tier and a 15.3 cents tier might apply above 2,000 kWh. Always verify the rate at the customer's actual monthly usage.
4. TDU Delivery Differences
Oncor, CenterPoint, AEP Texas Central, AEP Texas North, TNMP, and Sharyland each set delivery tariffs separately. CenterPoint's commercial delivery in 2026 runs about a half cent per kWh higher than Oncor on the same usage. A 7-cent CenterPoint rate is not comparable to a 7-cent Oncor rate without the TDU adjustment.
5. Demand Charge Structure
Demand-metered accounts pay $4 to $15 per kW per month based on peak demand. Some REPs quote energy-only and pass through TDU demand at the regulated tariff; others bundle demand into the energy line at a flat estimate. The first structure exposes the customer to demand-charge variability; the second smooths it. Compare on identical assumptions.
6. Demand Ratchet
Some commercial accounts pay a "ratcheted demand" charge based on the highest peak in the prior 12 months, even in months where actual demand is lower. A 50 kW peak last August continues to drive billing through the next 11 months. The ratchet is set in the TDU tariff and rarely appears in the EFL; verify it.
7. Auto-Renewal and Variable Rollover
The EFL discloses the early termination fee but not the post-term rate. After a fixed plan expires, the default rollover is to a variable rate at REP discretion, often 15-25 cents per kWh. The "2-year savings" projected from a 12-month quote disappears in month 13 if the renewal does not get shopped.
Six Common Errors When Buyers Compare Commercial Electricity Rates in Texas
These errors recur in PUCT complaints and broker post-mortems. They are the difference between a successful and a failed commercial electricity comparison.
1. Using a Single Bill for Forecasting
A January bill on a Texas commercial account understates summer load by 30-50%. Forecasting from one bill produces a contract too small for July, triggering bandwidth penalties or higher-tier rates. Pull at least 12 months, ideally 24, before quoting.
2. Comparing Different Contract Terms
A 12-month fixed at 6.97 cents and a 24-month fixed at 7.05 cents are not directly comparable. The 24-month locks more risk for less premium. Decide the term first based on the forecast horizon and forward curve shape, then compare REPs at that term.
3. Ignoring Base Charges
A 5.9 cents per kWh plan with a $20 base charge versus a 6.5 cents plan with no base, on a 5,000 kWh per month load:
- Plan A: (5.9 x 60,000) + $240 = $3,780
- Plan B: 6.5 x 60,000 = $3,900
Plan A wins by $120 per year. But on 25,000 kWh per month, Plan B wins because the base charge is amortized over higher volume. Always run the math at the customer's actual usage.
4. Missing the Bandwidth Penalty
A 90-110% bandwidth on a 100,000 kWh per month commitment exposes the customer when load drifts. A retail business closing for two weeks at Christmas falls below 90,000 kWh; the deficit gets bought back at index, billed at potentially higher than contract. Negotiate to 80-120% before signing.
5. Not Normalizing for TDU Territory
A buyer with locations in Houston (CenterPoint), Dallas (Oncor), and Corpus Christi (AEP Texas Central) cannot compare a single REP's quote against another's without breaking out the TDU layer. Each TDU charges differently for the same kWh.
6. Comparing Teaser Rates
Promotional rates with introductory pricing for 3-6 months that step up to a higher rate for the balance of the term. The EFL discloses the structure, but a buyer scanning the headline number can miss the step-up. Always read the "average price per kWh at 1,000 kWh per month" line on the EFL, which includes the step-up math.
Tools to Compare Commercial Electricity Rates Texas Owners Can Use
No PUCT-sponsored commercial price comparison portal exists (see the Power to Choose for business analysis for why). The available tools fall into three categories.
Direct REP EFLs
Pull the EFL from each REP listed in the PUCT REP directory. TXU Energy, Reliant, Direct Energy, Champion, APG&E, Gexa, Cirro, Constellation, and ENGIE all publish current commercial EFLs. The EFL is the canonical disclosure. This is the cheapest, slowest path: 5-10 EFLs to read carefully.
PUCT-Registered Brokers
Brokers compare across 20-50 REP partners and run the comparison worksheet for the buyer. The broker registry is searchable at the PUCT broker directory. Cost: 0.1-0.5 cents per kWh embedded in the contract rate. PUCT Project No. 49947 requires registered brokers to disclose commission in writing.
Third-Party Aggregators
ElectricityPlans.com, ChooseTexasPower.org, ChooseEnergy.com, and ComparePower.com offer commercial price comparisons. None are official; all reflect partner-REP relationships. Useful as a benchmark; not a substitute for direct quotes or broker engagement.
Frequently Asked Questions About Comparing Commercial Electricity Rates
What is the best way to compare commercial electricity rates in Texas? Build the five-line worksheet (energy + demand + TDU delivery + base/minimum/regulatory + taxes) and run every EFL through it on the customer's actual 12-24 month load profile. Compare the all-in annual cost, not the headline cents-per-kWh.
How do I get apples-to-apples EFLs from multiple REPs? Specify the same usage profile (monthly kWh, peak kW), the same start date, the same contract term, and the same TDU territory in every quote request. Sign a Letter of Authorization for each broker or REP under PUCT Rule 25.475 if historical usage data is required.
What is the standard commercial electricity comparison Texas consultants use to compare commercial electricity rates Texas REPs quote? The five-line worksheet above is the methodology used by most procurement consultants. The 5-line normalization process is documented in detail in the electricity rate comparison Texas ERCOT methodology.
Why do EFLs disclose only three usage tiers? PUCT Rule 25.475(c) standardizes EFL disclosure at three reference usage points. For commercial accounts, those are typically 5,000, 10,000, and 25,000 kWh per month. The buyer must interpolate or extrapolate to their actual usage; the EFL math does not always linearly extend.
Should I always work with a broker for a commercial electricity comparison? Not always. For loads under 100,000 kWh per year, direct REP shopping often produces the lowest rate because it avoids broker commission. For loads above that, broker leverage typically pays back the embedded commission. Use the worksheet either way; the broker only changes who runs the math.
What to Do Next
Pull the most recent business electricity bill, identify the ESI ID and contract end date, and request three to five EFLs on the customer's actual usage profile. Run the five-line worksheet. The pillar guide on commercial electricity rates in Texas covers the underlying rate stack, the retail electric provider Texas pillar lists the active commercial REPs, and EIA Form 826 commercial data sets the 8.6 cents per kWh sanity-check benchmark for any quote.
