The Short Answer
Texas electricity costs more than most Texans expect, and the reasons are structural, not accidental. The state runs a fully deregulated wholesale market with no traditional utility price cap, fuel costs pass directly to consumers, and the grid operates in isolation from the rest of the country. Each of those factors adds to your bill. Understanding them helps you shop more effectively rather than feeling at the mercy of forces you cannot name.
The median listed rate on Choose My Power's plan snapshot (as of October 21, 2026) is 14.7 cents per kilowatt-hour at 1,000 kWh per month across 127 live plans from 17 providers. That figure is a useful baseline because it reflects what real shoppers are actually choosing from, not a theoretical average.
Deregulation Did Not Guarantee Low Prices
When Texas deregulated its retail electricity market in 2002, the promise was competition. Competing providers would fight for customers, prices would fall, and consumers would benefit. That promise has been partially kept and partially broken, depending on how closely you look.
Competition does exist. Shoppers with time and a reliable comparison tool can find meaningful price differences between plans. The gap between the cheapest listed plan on Choose My Power (6.7 cents per kilowatt-hour all-in at 1,000 kWh, from APGE's SimpleSaver 9, in the lowest-cost utility area, as of October 21, 2026) and the median of 14.7 cents is not trivial. That spread is competition working.
But deregulation also removed the regulatory floors that historically kept prices stable in exchange for capping profit. Providers in a deregulated market can pass through wholesale cost spikes almost immediately. When natural gas prices surge, your retail bill follows within a billing cycle or two, especially if you are on a variable-rate plan. Regulated utilities in other states absorb some of that volatility through rate-case proceedings that unfold over months or years. Texas does not have that buffer.
The Public Utility Commission of Texas (PUCT) oversees the retail market and sets rules for disclosure, billing, and provider licensing, but it does not set retail electricity rates. That is a deliberate policy choice, not an oversight.
Natural Gas Prices Set the Floor
Natural gas supplies about 43 to 44 percent of ERCOT electricity generation on an annual basis, with the share running higher in winter and in periods of low wind and solar output and lower on sunny spring and summer afternoons (EIA, ERCOT generation data, 2021-2025). Because natural gas is often the marginal fuel, meaning the last and most expensive source called on to meet demand, its price heavily influences the wholesale clearing price for the entire market.
This creates a direct link between global energy markets and your household bill. When liquefied natural gas exports tighten domestic supply, when a cold snap spikes heating demand across the country, or when pipeline disruptions occur, Texas wholesale prices respond within hours. The February 2021 winter storm (Winter Storm Uri) demonstrated this at an extreme scale: wholesale prices hit the $9,000 per megawatt-hour market cap for extended periods while millions of homes lost power. The retail fallout, including astronomical variable-rate bills for some customers, followed directly from that wholesale structure.
Fixed-rate plans shield you from those spikes during a contract term, which is one reason shopping carefully matters. Variable-rate plans are priced more flexibly but carry the full exposure to wholesale volatility.
The Grid Is an Island
ERCOT operates largely as an electrical island. It connects only minimally to neighboring grids, which limits the ability to import cheaper power from other states when Texas prices spike, or to export surplus when generation outpaces demand.
Most U.S. grids are interconnected through the Eastern or Western Interconnection, allowing power to flow across state lines and smooth out regional price differences. ERCOT's isolation is partly historical and partly intentional: keeping the grid within Texas borders has traditionally allowed the state to avoid federal regulation by the Federal Energy Regulatory Commission (FERC). That regulatory independence has come with a resilience tradeoff.
When a heat wave pushes Texas demand to record levels, Texas cannot easily pull in power from New Mexico or Louisiana at scale. Prices rise, sometimes sharply. When generators fail in cold weather, the same constraint applies. The grid's insularity is not inherently bad engineering, but it means Texas prices are more sensitive to local conditions than prices in more interconnected regions.
The Capacity Market Question
Most deregulated electricity markets maintain a formal capacity market, a mechanism that pays generators to stay available even when they are not running, to ensure reliability. ERCOT does not. Instead, it relies on what regulators call an energy-only market, where generators earn revenue by selling electricity when it is needed and earn nothing when it is not.
The argument for this design is that it avoids paying for idle capacity that may never be needed. The argument against it is that it reduces the financial incentive for generators to maintain or expand supply, particularly for the kind of peaking capacity that only runs during extreme weather.
After Winter Storm Uri, the PUCT and the Texas Legislature proposed a Performance Credit Mechanism, which the PUCT shelved in December 2024, and a dispatchable reliability reserve service, both designed to address the capacity shortfall without building a full capacity market (PUCT, Project No. 52373, 2021-2023). The debate continues. What is clear is that the energy-only design, combined with the grid's isolation, means Texas prices can spike higher and faster than markets with capacity payments and interstate connections.
How Bill Structure Adds a Hidden Cost
Beyond wholesale and structural factors, retail plan design creates its own layer of cost complexity. Sixteen of the 127 plans listed on Choose My Power (as of October 21, 2026) carry a bill-credit cliff, where a household using 500 kWh in a month pays $25 or more above what a household using 1,000 kWh pays. That is not a pricing error; it is a deliberate structure where a large bill credit triggers only at a usage threshold.
A household that keeps its consumption below the threshold, perhaps because of mild weather or efficient appliances, ends up paying a higher effective rate than the advertised number suggests. Comparing only the headline cents-per-kilowatt-hour figure without checking the bill-credit structure leads to genuine financial surprises.
When Switching Does Not Help
If a household is already on a fixed-rate plan priced near the low end of the market, switching carries real costs: early termination fees, administrative time, and the risk of landing on a plan with a worse structure. Switching makes sense when a current contract is expiring, when a variable rate has drifted well above fixed-rate alternatives, or when a plan has a bill-credit cliff that does not fit a household's actual usage pattern.
Switching does not solve the underlying structural factors. Natural gas prices, grid isolation, and market design are not affected by which provider issues the bill. What switching does is allow a household to position itself on the better side of the spread between the cheapest available plan and the median, and that spread, as the October 2026 snapshot shows, is substantial.
What to Take Away
Texas electricity bills are high relative to national medians for identifiable reasons: a fully exposed wholesale market tied to natural gas, a grid that cannot easily import cheaper out-of-state power, a capacity design that concentrates price spikes into short windows, and retail plan structures that reward careful reading over casual shopping. None of those factors are going away in the near term.
The practical response is not resignation. It is using comparison tools that show all-in pricing at realistic usage levels, reading the Electricity Facts Label before signing, and understanding which plan structures fit a household's actual consumption. The structural disadvantages are real, but the spread between the most expensive and least expensive plans in the current market is large enough that shopping well still makes a meaningful difference on a monthly bill.
