Commercial Electricity Rates in Texas

What does a small business actually pay for electricity in Texas? Between 4.8¢/kWh on Oncor’s territory and 5.4¢/kWh on AEP Texas — an average of 5.1¢/kWh across the 3 utilities serving the state.

That’s just the energy line. Demand charges, customer charges, and riders sit on top — the part most quotes leave out. This page breaks down the full picture and points you to where to shop.

How Texas bills commercial electricity

Texas runs the most open commercial electricity market in the country. Your transmission and distribution utility (TDU) — Oncor, CenterPoint, or AEP Texas — delivers the power and files delivery tariffs with the PUCT, but every kilowatt-hour of supply gets sold competitively by a Retail Electric Provider. For a small business, that means two cost layers: a fixed delivery tariff (set by the TDU) and a market-priced energy contract you negotiate with a REP.

Commercial rate schedules look different from the residential one you might know. Three pieces show up on almost every small-business bill: a flat customer charge ($10-$50/month regardless of usage), an energy charge measured in cents per kWh, and — once you cross a size threshold — a demand charge measured in dollars per kW based on your single highest 15-minute usage spike during the billing month. The demand charge surprises new business owners more than anything else, because one bad afternoon of running every machine at once can spike a whole month’s bill.

Many Texas utilities also enforce time-of-use pricing for commercial customers above a certain demand level. Energy used during summer afternoon peaks (typically 2-7 PM on weekdays) costs more than energy used overnight or on weekends. For businesses with flexible schedules, shifting heavy loads to off-peak windows is one of the cleanest ways to cut a bill without changing suppliers.

Small-business rates vs. residential rates in Texas

Commercial energy rates are usually lower per kWh than residential rates — but the demand charge and customer charge can erase that headline savings if your business has spiky load. Here’s the comparison for each utility, using the most common small-business rate schedule (typically GS-1, G-1, or equivalent) versus the same utility’s residential rate.

Utility Small-business Service area
Oncor 4.8¢ North, Central, and West Texas (Dallas-Fort Worth, Waco, Tyler, Midland)
CenterPoint 5.1¢ Greater Houston area and Gulf Coast
AEP Texas 5.4¢ South Texas (Corpus Christi, Laredo, Harlingen) and parts of West/North Texas (Abilene, Vernon)

Energy rates shown reflect the most recent small-business tariff filing for each utility. Demand charges, customer charges, and riders are billed separately — see the per-utility page for the full structure. Residential rate is a Texas-wide average for comparison only.

What separates commercial rates from residential

If you’ve only ever shopped a residential plan, four things will feel new on a commercial tariff. Get clear on these before you compare quotes.

1. The demand charge ($/kW)

Once your business pulls more than 10 kW (in most Texas territories), the utility bills you on your single highest 15-minute usage spike during the month — not your average usage. A bakery that turns every oven on at 6 AM for one hour can pay for that peak all month long. Spreading load across the day cuts this bill more than any rate shopping.

2. Time-of-use is often mandatory

Texas utilities push commercial customers onto time-of-use schedules above a size threshold (around 700 kW). That means summer-afternoon kWh cost 2-3× more than overnight kWh. Restaurants, manufacturing, and refrigeration-heavy businesses watch this number closely; office users mostly absorb it because their load matches the peak window anyway.

3. Riders and adjustments stack up

Beyond energy + demand + customer charge, commercial bills carry riders for transmission, ancillary services, renewable mandates, and utility recovery clauses. These can add 1.5-3¢/kWh on top of the headline energy rate and they’re often quoted separately in supplier offers. Always ask suppliers to quote all-in, not just the energy component.

4. REPs sell longer terms

Commercial REPs quote 12-, 24-, and 36-month fixed contracts and price each one against the forward power curve at quote time. A 36-month contract isn’t automatically cheaper — it just locks you in longer. Get quotes from three REPs on the same usage profile before signing.

Most Texas business owners also pay a residential bill at home. These tools and pages cover both sides.
