Why Published Rate Data Matters for Texas Commercial Energy Buyers

Commercial electricity procurement in Texas operates in an information gap. While residential buyers have Power to Choose, commercial buyers navigate a fragmented market with no centralized pricing data.

The Commercial Rate Visibility Problem

Texas deregulated its electricity market in 2002, creating one of the most competitive retail energy markets in the world. For residential customers, the Power to Choose website (run by the PUC) provides a centralized comparison tool. Commercial buyers have no equivalent.

The Public Utility Commission of Texas (PUCT) mandates that Retail Electric Providers (REPs) file Electricity Facts Labels (EFLs) for plans serving customers under 50 kW demand. But there is no centralized commercial rate database. ERCOT handles wholesale operations, not retail pricing. The EIA publishes state-level averages, not plan-level comparisons.

This means commercial electricity buyers, property managers, and energy procurement teams are negotiating contracts with limited visibility into what other REPs charge for comparable service.

What Published Rate Data Reveals

Not all commercial electricity pricing is hidden behind custom quotes. A meaningful segment of the market, roughly 19 active REPs and over 40 published plans, offers transparent pricing for small to mid-size commercial customers (typically under 50 kW demand).

This published rate data shows:

  • Rate ranges by TDU territory: Pricing varies significantly across Oncor, CenterPoint, AEP North, AEP Central, and TNMP service areas due to different delivery charges.
  • Contract term structures: Fixed-rate plans from 12 to 36 months, variable/month-to-month plans, and hybrid block-and-index structures.
  • Competitive positioning: Which REPs consistently offer below-median rates, and which are positioned as premium providers.
  • Price movement trends: How rates shift in response to wholesale natural gas prices, seasonal demand, and ERCOT market conditions.

Impact on Your Next Contract

Benchmark Before You Negotiate

If you know the median published rate in your TDU territory is 8.5 cents/kWh and your REP quotes 11.2 cents/kWh, you have leverage. Published rate data gives procurement teams an independent benchmark that does not rely on the broker or REP providing it.

Timing Matters

Commercial rates in Texas correlate with ERCOT wholesale prices, natural gas futures, and seasonal demand patterns. Locking a 36-month contract during a price dip can save thousands per year. Conversely, renewing during a summer peak may lock in elevated rates for years.

TDU Delivery Charges Are Not Negotiable

Your TDU (Transmission and Distribution Utility) sets delivery charges that are the same regardless of which REP you choose. What varies is the energy rate, base charges, and contract terms. Understanding the full cost breakdown prevents comparing apples to oranges.

What You Should Do

  1. Check when your contract expires. Start evaluating alternatives 60 to 90 days before expiration to avoid automatic renewals at higher rates.
  2. Know your TDU territory. Your delivery charges are fixed by territory. Compare energy rates within your TDU for meaningful comparisons.
  3. Request EFLs from multiple REPs. Ask for the Electricity Facts Label, not just a quote. EFLs standardize pricing disclosure.
  4. Compare total cost, not just energy rate. Base charges, minimum usage fees, and early termination penalties all affect total cost of ownership.
  5. Track market trends. Published rate data shows whether the market is trending up or down, informing whether to lock in now or wait.

Questions to Ask Your REP or Broker

  • How does your proposed rate compare to the median published commercial rate in my TDU territory?
  • What is the early termination fee, and is it per remaining month or a flat charge?
  • Does this rate include all TDU pass-through charges, or are those billed separately?
  • What happens to my rate at contract expiration if I do not actively renew?
  • Are there any demand charges or capacity fees that apply above a certain usage threshold?

Frequently Asked Questions

What is a TDU and why does it affect my rate?

A Transmission and Distribution Utility (TDU) owns and maintains the power lines in your area. In Texas, the five major TDUs are Oncor, CenterPoint, AEP North, AEP Central, and TNMP. Their delivery charges are regulated by the PUCT and are the same regardless of which REP you choose. Your total electricity cost is your REP's energy rate plus TDU delivery charges.

How many REPs publish commercial rates?

Currently, about 19 REPs publish standardized commercial electricity rates. This covers primarily small to mid-size commercial customers under 50 kW demand. Larger industrial customers (1 MW+) typically receive custom quotes that are not published.

How often do published commercial rates change?

Rate changes vary by REP. Some adjust monthly based on wholesale market conditions. Others maintain rates for extended periods. On average, meaningful rate shifts occur every 2 to 4 weeks across the market.
