Texas and Ohio are two of the largest deregulated electricity markets in the United States. Both give consumers the power to choose their electricity provider, but the way each market is structured can lead to very different experiences. If you are shopping for electricity in either state, here is what you need to know about how they compare.
Different Grids, Different Rules
The most fundamental difference is the grid itself. Texas operates its own independent power grid managed by ERCOT (the Electric Reliability Council of Texas). This grid is almost entirely contained within the state and is not subject to federal oversight by FERC, the Federal Energy Regulatory Commission.
Ohio, on the other hand, is part of the PJM Interconnection, a regional grid that spans 13 states and the District of Columbia. Because PJM crosses state lines, it is regulated by FERC. This means Ohio's wholesale electricity market operates under a different set of rules than Texas.
How You Shop for Electricity
In Texas, the shopping experience is fully retail-driven. You choose a retail electricity provider (REP) that handles your supply, billing, and customer service. Your local utility, such as Oncor or CenterPoint, only manages the physical delivery of electricity. You typically never interact with the utility directly for billing purposes.
In Ohio, the process is a bit different. You choose a competitive retail electric service (CRES) provider for the supply portion of your bill, but your local utility still handles delivery and often sends a combined bill that includes both the supply and delivery charges. This dual-billing structure means your utility remains a more visible part of the relationship.
Plan Variety and Flexibility
Texas tends to offer a wider variety of plan types. You will find fixed-rate plans, variable-rate plans, time-of-use plans, free nights and weekends plans, prepaid plans, and 100 percent renewable options. The sheer number of providers competing in the Texas market drives innovation in plan design.
Ohio's market is competitive but generally offers fewer exotic plan structures. Most Ohio plans are either fixed-rate or variable-rate. Renewable energy options exist but are less common than in Texas. Contract lengths in Ohio tend to be shorter, and the overall selection is more straightforward.
Default Rates and Safety Nets
If you do not choose a provider in Ohio, you default to your utility's Standard Service Offer (SSO), which is a rate set through a competitive auction. This provides a built-in safety net that ensures you are still getting a market-based rate even without actively shopping.
In Texas, there is no equivalent default rate in the same sense. If you move to a new address and do not choose a provider, you may be placed on a Provider of Last Resort (POLR) rate, which is typically much higher than standard market rates. This makes it more important to actively shop when you are in Texas.
Price Volatility
Texas is known for more dramatic price swings in the wholesale market, driven by its isolated grid and extreme weather. Summer heat waves and winter storms can cause wholesale prices to spike sharply, which can affect variable-rate customers almost immediately.
Ohio's connection to the broader PJM grid provides more stability. The ability to import power from neighboring states helps cushion the impact of local supply disruptions. That said, Ohio is not immune to price fluctuations, particularly during periods of high demand or when natural gas prices rise.
Regulation and Consumer Protection
Both states have regulatory bodies that oversee consumer protection. In Texas, the Public Utility Commission of Texas (PUCT) sets the rules for the retail market. In Ohio, the Public Utilities Commission of Ohio (PUCO) serves a similar function. Both require providers to disclose key plan details, but the specific requirements differ. Texas, for example, requires an Electricity Facts Label on every plan, which provides a standardized way to compare costs.
What This Means for You
Whether you live in Texas or Ohio, the ability to choose your electricity provider is a valuable tool. The key is to understand how your specific market works so you can make informed comparisons.
