Dallas-Fort Worth Business Electricity

The Dallas-Fort Worth metroplex runs on Oncor, the largest transmission and distribution utility in Texas, inside ERCOT's North load zone. For most DFW businesses that means full retail choice, aggressive supplier competition, and a market where a well-run procurement process reliably beats a renewal letter by double digits.

But DFW has a wrinkle no other Texas metro has to the same degree: a meaningful number of businesses in the region are not in a deregulated territory at all. Before you shop, you need to know which market you are actually in.

First: Are You Even in a Competitive Territory?

Texas deregulation applied to investor-owned utilities. Municipally owned utilities and electric cooperatives were allowed to opt in — and most did not. In and around DFW, that means:

• Oncor territory — competitive. Dallas, Fort Worth, Arlington, Irving, Plano, Frisco, Richardson, Carrollton, and most of the metroplex. Full retail choice.
• Municipal utilities — not competitive. Garland (GP&L), Denton (DME), Greenville (GEUS), and several smaller cities operate their own electric systems. Businesses there buy from the city and cannot shop supply.
• Electric cooperatives — usually not competitive. CoServ, Tri-County, and other co-ops serve fast-growing collar-county areas around DFW. Most have not opted into retail choice.

This matters operationally, not just academically. A DFW company with sites in Plano, Denton, and a distribution center in a co-op territory has three different procurement situations in one portfolio — and the two non-competitive sites still have real levers (rate schedule, demand management, efficiency), just not supplier shopping.

How a DFW Commercial Bill Is Built

In Oncor territory, your bill separates into parts you can negotiate and parts you cannot:

• Supply (negotiable). Sold by your retail electric provider. This is the energy commodity plus the REP's margin, risk premium, and whatever they have or have not fixed for you.
• Oncor delivery (not negotiable, but optimizable). Regulated per-kWh and per-kW charges set by the Public Utility Commission of Texas. You cannot shop these — but you can be on the wrong rate schedule for them, and many DFW businesses are.
• Transmission cost allocation (controllable). Allocated to large interval-metered customers through the Four Coincident Peak method. See below.
• ERCOT fees and ancillary services. Small line items where "fixed price" contracts frequently are not fixed.

When DFW businesses tell us their rate went up mid-contract, the cause is usually one of two things: an Oncor delivery adjustment passing through, or an ancillary services clause in a contract that was sold as fixed. Both are visible in the contract language before you sign. Our guide to reading a commercial electric bill shows where each one lands.

4CP: A Six-Figure Line Item Set by Four Intervals

ERCOT allocates transmission costs to large commercial and industrial customers based on their demand during four 15-minute intervals — the ERCOT-wide system peaks in June, July, August, and September. Your average demand across those four intervals sets your transmission charges for the following year.

DFW's summer peaks are brutal and predictable in shape if not in exact timing, which makes 4CP one of the largest genuinely controllable costs for any interval-metered facility in Oncor territory. A distribution center that can idle conveyors, a manufacturer that can shift a shift, or a campus that can pre-cool has an annually recurring savings opportunity that has nothing to do with supplier price.

The practical problem is timing: you have to act on the right afternoon, and you only find out afterward whether you got it right. That is a discipline question, and it is what peak load management programs exist to solve.

DFW Load Profiles and What They Should Cost

Retail providers price your usage pattern, not your address. The metroplex's major commercial segments each price differently:

• Warehouse and logistics. The I-35E, I-20, and Alliance corridors hold one of the densest concentrations of distribution space in North America. These loads are lighting- and HVAC-driven with dock-equipment demand spikes — often on a suboptimal Oncor rate class and rarely aggregated across sites. See how warehouse energy costs behave for the general pattern.
• Data centers. DFW is a top-five U.S. data center market. Near-perfect load factor makes these the most attractive shape in ERCOT — and their growth is a primary driver of the forward curve every other Texas buyer now prices against. See Texas data center energy costs.
• Corporate campuses and office portfolios. Weekday-daytime load with a poor coincidence to nothing in particular — meaning both good aggregation candidates and good demand-management candidates.
• Manufacturing. High load factor when running multiple shifts, which should earn a tighter supplier margin than most DFW plants are actually getting. See Texas manufacturing energy costs.
• Retail and restaurant chains. Dozens of small meters that individually have no leverage and collectively have quite a lot — the classic case for multi-site procurement.

Where DFW Businesses Lose Money

• Auto-renewing. Evergreen and auto-renewal clauses are common in Texas commercial contracts, and a missed notice window can lock you into another term at a rate nobody negotiated. Know your notice date before you know your renewal price.
• Shopping on price alone. Bandwidth clauses, material change provisions, and pass-through ancillaries make two quotes with the same number into two different products. The cheapest headline rate frequently is not the cheapest contract.
• Leaving the rate schedule alone for a decade. A facility that added or removed load has probably outgrown its Oncor rate class. Tariff optimization costs nothing but analysis and recurs every month.
• Splitting the portfolio. Sites signed at different times with different suppliers give you no leverage and four renewal fire drills a year instead of one negotiation.
• Never auditing. Meter multiplier errors, stale demand ratchets, and misapplied riders survive for years because nobody checks. A bill audit recovers retroactively.

What to Do Next

Start by establishing three facts about every DFW site you operate: which territory it is in, what your contract actually fixes versus passes through, and when your notice window opens. Almost every avoidable cost in this market traces back to not knowing one of those three.

From there, run a real solicitation — identical terms sent to every credible provider on the same day, so the numbers compare — and time it into a window rather than against a deadline. Our guide to when to lock in energy rates covers how to think about the ERCOT forward curve, and RFP versus reverse auction covers how to structure the process itself.

Frequently Asked Questions

Can every Dallas business choose its electricity supplier?

No. Businesses in Oncor territory — which covers Dallas, Fort Worth, and most of the metroplex — have full retail choice. Businesses served by municipal utilities such as Garland Power & Light or Denton Municipal Electric, or by electric cooperatives like CoServ, generally cannot shop for supply.

Is electricity cheaper in Dallas than in Houston?

Not reliably. Both sit in ERCOT and both shop the same wholesale market, but they are in different load zones (North versus Houston), so congestion can push their prices apart in either direction at any given moment. Delivery charges also differ because Oncor and CenterPoint have separate approved tariffs. The gap between two suppliers quoting the same DFW building is almost always larger than the gap between Dallas and Houston.

What is a demand ratchet and does it apply in DFW?

A ratchet means your billed demand for a month is set by a percentage of your highest demand over the prior twelve months, not by that month's actual peak. It appears in some Texas delivery tariffs, and it means one bad fifteen-minute spike can raise your bills for a year. It is a strong argument for demand monitoring on any facility with variable load.

How long should a DFW commercial electricity contract be?

Term length is a market-timing decision, not a policy. Longer terms buy budget certainty and lock in whatever the curve currently prices; shorter terms preserve flexibility to re-price. The right answer depends on where the ERCOT forward curve sits relative to its recent range on the day you sign, and on how much price volatility your business can absorb.

Do I need to notify Oncor when I switch suppliers?

No. Your new retail provider initiates the switch through ERCOT's systems. Oncor continues to deliver power and read your meter exactly as before, and there is no service interruption.
