ERCOT manages the flow of power to 27+ million Texans — about 90% of the state's load — and runs the competitive market that lets businesses in deregulated areas choose their electricity provider. Elite Energy Consultants helps you navigate that market and source rates from 25+ REPs.
Get A Free QuoteERCOT — the Electric Reliability Council of Texas — is the independent system operator (ISO) that manages the grid serving about 90% of the state's electric load. It is a membership-based 501(c)(4) nonprofit overseen by the Public Utility Commission of Texas (PUCT) and the Texas Legislature. Every five minutes, ERCOT balances supply and demand across more than 1,460 generation units and 55,000+ miles of transmission lines, and it runs the competitive market where over 8 million premises can choose their electricity provider.
Just as important is what ERCOT does not do: it doesn't sell power, doesn't own the wires, and will never send you a bill. In the deregulated market, Retail Electric Providers (REPs) sell electricity and Transmission and Distribution Utilities (TDUs) deliver it — see the difference between a REP and a TDU, or our Texas electricity glossary for any term on this page.
If your business operates anywhere in ERCOT's deregulated territory, the market ERCOT runs sets the backdrop for every supply contract you sign — which is why understanding it pays off when you shop commercial electricity rates in Texas.
The continental United States runs on three power grids: the Eastern Interconnection, the Western Interconnection, and Texas. Because the ERCOT grid stays within state lines, it largely escapes federal (FERC) rate jurisdiction — Texas writes its own market rules.
The independence is older than the agency: Texas utilities banded together as the Texas Interconnected System during World War II (1941) to power Gulf Coast war production, ERCOT was formed in 1970 to manage the grid, and Senate Bill 7 (1999) opened retail competition on January 1, 2002 — the moment Texas businesses gained the right to choose their electricity supplier. Here's how deregulation works in Texas in detail.
For your business, independence means three things: market rules are set in Austin, not Washington; market changes roll out faster than anywhere else in the country; and price signals — not regulated rates — drive everything from generator investment to the offers REPs put in front of you.
Generators sell power into day-ahead and real-time markets where prices settle every 15 minutes at thousands of points on the grid — and can spike sharply when reserves run thin. Read how ERCOT wholesale pricing works for the full mechanics.
REPs buy wholesale power and compete for your supply contract — that's the rate you shop. Your TDU still delivers the power over its wires and charges regulated delivery fees that are identical no matter which REP you choose.
Real-Time Co-optimization + Batteries went live December 5, 2025 — ERCOT's biggest market redesign in 15 years. It prices energy and reserves together every five minutes and is projected to save the market $1B+ per year.
Driven by data centers and electrification, ERCOT forecasts record demand through 2032 — summer 2026 peak load is projected at 90.5–98 GW against the all-time record of 85.5 GW. Growing demand shapes the prices behind every contract offer.
You never pay ERCOT directly — but the market it runs sets the price behind every contract a REP will offer you.
Wholesale conditions — fuel costs, weather, reserves, summer peaks — determine the futures prices REPs use to build their offers. The same business can see offers swing 20%+ depending on when it goes to market.
A fixed rate locks your price for the term; an index plan floats with the market. Larger loads also carry 4CP and demand charges shaped by load factor and demand charges — often the hidden lever in your bill.
We compare 25+ REPs against your load profile and time your renewal to market conditions. We're paid by the REP you choose — not by you — and we work the market daily so you don't have to.
About 85% of Texans live in deregulated areas — 173 of 254 counties, with retail choice since January 1, 2002. Six utilities deliver the power; find yours below.
Dallas–Fort Worth and North, Central & West Texas — the largest TDU in the state.
Greater Houston and the upper Gulf Coast.
Corpus Christi, Laredo and the Rio Grande Valley.
Abilene, San Angelo and the Big Country of West Texas.
Gulf Coast south of Houston, plus North Central and West Texas pockets.
Lubbock — a municipal utility that voluntarily joined ERCOT retail choice.
* Served by two utilities — different parts of the city fall under different wires companies. † Parts of the city are served by a municipal or non-ERCOT utility. TDU boundaries don't follow city limits, so the only reliable answer is an address-level (ESID) check — send us your address and we'll verify it for free.
Who can't choose: Austin (Austin Energy), San Antonio (CPS Energy), El Paso (El Paso Electric), Amarillo and the north Panhandle (Xcel), Beaumont–Port Arthur and much of East Texas (Entergy), northeast Texas (SWEPCO), and electric co-op territories are outside retail choice. If your business is anywhere in the six territories above, we can shop the market for you.

Common questions from Texas business owners about ERCOT, the grid, and what deregulation means for their electricity bill.
ERCOT stands for the Electric Reliability Council of Texas. It is the independent system operator that manages the flow of electricity across about 90 percent of the Texas grid, serving more than 27 million customers. ERCOT schedules power across 55,000+ miles of transmission lines, operates the wholesale electricity market where prices settle every 15 minutes, and administers the retail switching system that lets businesses in deregulated areas choose their own electricity provider.
No. ERCOT does not sell electricity, own power lines, or bill customers. It is a nonprofit grid and market operator. In the deregulated Texas market, Retail Electric Providers (REPs) sell you electricity, and your local Transmission and Distribution Utility (TDU) — such as Oncor or CenterPoint — delivers it over its wires and maintains the meter.
The continental U.S. runs on three power grids: the Eastern Interconnection, the Western Interconnection, and ERCOT. Texas utilities deliberately kept their grid within state lines so it would not cross state borders and fall under federal rate regulation. Because ERCOT is intrastate, it operates largely outside FERC jurisdiction — Texas sets its own market rules, which is why the state could open retail competition in 2002 and continues to redesign its market faster than other regions.
Deregulation follows utility service territory, not city limits, so the only reliable check is at the address level. Every meter in the ERCOT market has an ESID (Electricity Service Identifier) that tells us exactly which utility serves it and whether the location can choose a provider. Send us your address or a copy of your bill and we will verify it for free. Residential customers can also check powertochoose.org, the PUCT's official shopping site.
If you are on a fixed-rate plan, your price per kWh is locked for the contract term — daily ERCOT wholesale swings do not change your rate. Where the market matters is at renewal: the futures prices REPs use to build their offers move with ERCOT market conditions, so the timing of your renewal can swing your next contract rate significantly. That is why we track the market and start shopping your renewal months before your contract ends.
Yes. Lubbock Power & Light moved its load onto the ERCOT grid and opened its market to retail competition in January 2024, making Lubbock the newest deregulated city in Texas. Lubbock businesses can now choose from competing providers for the first time.
