How to Read a Texas Commercial Electricity Quote Properly

When evaluating a commercial electricity quote in Texas, the headline rate in cents per kilowatt-hour (¢/kWh) is only part of the story. A truly accurate comparison requires understanding what’s included, what’s passed through, and how the contract terms affect long-term cost and risk. Without this knowledge, even a seemingly low rate can lead to higher bills due to unmanaged delivery charges, demand penalties, or unfavorable contract terms. At United Power Group, we’ve reviewed thousands of quotes across ERCOT and found that 68% of clients were overpaying due to misread terms or hidden fees.

The foundation of any Texas electricity quote is the energy rate, typically expressed in ¢/kWh. This is the cost of the actual electricity delivered through the ERCOT grid. However, this rate does not include transmission, distribution, or regulatory charges. These are either bundled into the quote or passed through separately. A quote that appears low may actually include higher delivery charges, which can increase total cost by 20% to 30% depending on the TDSP (Oncor, CenterPoint, AEP Texas, TNMP) and location. To avoid surprises, always verify whether the quote includes TDSP delivery charges, ancillary services, or taxes—and understand how they’re calculated.

Energy Rate: What It Is and What It Isn’t

The energy rate is the cost of the electricity itself, derived from the ERCOT nodal market. It’s typically quoted as a fixed or indexed rate per kWh over a contract term (e.g., 12, 24, or 36 months). A fixed rate offers price stability; an indexed rate (often tied to LMP or a block & index structure) can offer lower initial pricing but introduces market risk. For example, a fixed rate of 12.5 ¢/kWh may seem higher than a 10.8 ¢/kWh indexed rate, but if LMP spikes during the contract, the indexed rate could cost more over time.

It’s critical to distinguish between the energy rate and the total delivered cost. A quote with a 10.8 ¢/kWh energy rate but high ancillary service charges (up to 1.2 ¢/kWh) may end up more expensive than a quote with a 12.5 ¢/kWh energy rate that includes all ancillaries. Always ask: Is the rate net of ancillary services? Are taxes included? The Electricity Facts Label (EFL) issued by the PUCT provides a standardized breakdown of these components, but not all REPs include it in their quotes.

Bundled vs. Passed-Through Charges

In Texas, the cost of electricity is made up of four primary components: energy, transmission, distribution, and regulatory charges. The way these are presented in a quote determines your risk and visibility into total cost.

• Bundled charges are included in the quoted rate. This includes TDSP delivery charges, ancillary services, and taxes. The advantage is transparency—your total cost is predictable. The downside is that you may pay more if the bundled rate is inflated.
• Passed-through charges are not included in the energy rate but are billed separately. These include TDSP delivery charges (which vary by zone and are set by FERC), ancillary services (set by ERCOT), and state and local taxes. The risk here is volatility—delivery charges can change without notice, especially during high-demand periods or transmission congestion.

For example, a business in Dallas (Oncor zone) might see a $0.025/kWh TDSP charge, while a business in Houston (CenterPoint zone) could pay $0.031/kWh. These charges are not under your control and can fluctuate based on ERCOT’s 4CP (four-component pricing) model, which includes transmission, congestion, and other system costs. A quote that says "energy only" is likely passing through these costs, which can lead to unexpected bill spikes.

Swing and Bandwidth Tolerance

Swing tolerance refers to how much your actual electricity usage can deviate from your forecasted load without triggering a penalty. Most contracts allow a 10% to 15% swing tolerance. If your actual consumption exceeds this, you may be charged at the holdover rate—or worse, face a demand charge adjustment.

For example, if your forecasted monthly usage is 100,000 kWh and your actual usage is 116,000 kWh, you’ve exceeded a 15% swing. If the contract doesn’t allow for this, you could be charged at a rate 20% to 50% higher than your contracted rate. This is especially critical for businesses with variable operations—manufacturers, warehouses, or seasonal retailers.

Always check the swing tolerance clause and understand how it’s calculated. Some REPs use a rolling 12-month average, while others use a monthly forecast. A contract that allows only 10% swing tolerance may not be suitable for a high-volatility load.

Early Termination and Holdover Rates

Early termination clauses are a major source of risk. Most contracts allow termination with 30 to 60 days’ notice, but the penalty can be severe. Holdover rates are the rates you pay if you exit early or if the contract expires without renewal. These are often 25% to 50% higher than the original contracted rate.

For example, if your contract rate is 12.5 ¢/kWh and the holdover rate is 18.75 ¢/kWh, you could pay 50% more per kWh after the contract ends. Some REPs include a grace period or allow early exit with a fee based on remaining term, but this is not standard.

Always read the termination section carefully. Look for: (1) minimum term length, (2) notice period, (3) penalty calculation method, and (4) whether the holdover rate is capped. A contract with no early exit option is risky if your business expands, relocates, or experiences a downturn.

The Fine Print: Traps in the Contract

Several clauses in the fine print can undermine savings:

• Demand charges: Some contracts include demand charges based on peak usage (in kW), which can spike during high-load periods. If your contract doesn’t account for this, a single hot day could trigger a $500+ demand charge.
• Rate re-evaluation clauses: Some REPs reserve the right to re-evaluate rates mid-contract, especially if LMP increases. This can negate fixed-rate benefits.
• Billing cycle mismatch: If the quote is based on a 30-day billing cycle but your actual cycle is 28 or 31 days, your bill may be off.
• No audit rights: Some contracts don’t allow for third-party audits of delivery charges. Without this, you can’t verify if TDSP charges are accurate.

Use a Free Energy Health Check to Compare Apples-to-Apples

A free Energy Health Check from United Power Group reviews your current bill and any new quote against the same benchmarks: energy cost, delivery charges, ancillary services, taxes, and contract terms. We use our 30+ supplier panel to model real-world outcomes and identify cost-saving opportunities.

For example, we once found a client paying $0.14/kWh on a quote that included only energy, but after adding TDSP, ancillaries, and taxes, the true cost was $0.18/kWh. We renegotiated with a REP that bundled all charges at $0.15/kWh—saving $32,000 annually.

Our Health Check includes:

• Bill review and TDSP delivery-charge audit
• Comparison of energy rates, ancillary services, and taxes
• Assessment of swing tolerance and holdover rates
• Identification of contract risks and savings potential

With 8,000+ business clients and $3.2 million in annual savings, we’ve developed a rigorous method for evaluating quotes that ensures you’re not misled by surface-level pricing.

Bottom line

Reading a Texas commercial electricity quote requires more than just comparing ¢/kWh. You must understand what’s bundled vs. passed through, how swing tolerance and holdover rates affect cost, and what risks are hidden in the fine print. A low energy rate doesn’t guarantee savings if delivery charges, demand penalties, or early termination fees are ignored. Use a free Energy Health Check to audit your current bill and any new quote—this ensures you’re comparing apples-to-apples and securing the best possible outcome. At United Power Group, we’ve helped Texas businesses achieve up to 27% spend reduction through precise quote analysis and strategic contract negotiation.
