Texas has its own electrical grid, managed by the Electric Reliability Council of Texas (ERCOT), which supplies power to 90% of the state. The Texas grid is independent from the country's two other electrical grids, which cover the eastern and western United States. Texas has long refused to connect its decentralized grid to the two national power networks, but some experts argue that doing so would allow the state to buy and sell energy with the rest of the country and provide backup connections during times of crisis. While Texas has connections to the Eastern Interconnect and the power grid in Mexico, these ties only allow for the transfer of small amounts of power.

What You'll Learn
Texas' independent power grid
Texas is the only state in the continental US with its own electrical grid, known as the Texas Interconnection. The Electric Reliability Council of Texas (ERCOT) manages the flow of electric power on the Texas Interconnection, which supplies power to 26 million customers, or about 90% of the state's electrical load.
The Texas Interconnection is one of three minor grids in the North American power transmission grid. The other two minor interconnections are the Quebec Interconnection and the Alaska Interconnection. The two major interconnections are the Eastern Interconnection and the Western Interconnection. The Texas Interconnection is maintained as a separate grid for political, rather than technical reasons. By not crossing state lines, the synchronous power grid is in most respects not subject to federal regulation by the Federal Energy Regulatory Commission.
The Texas grid is independent from the country's two other electrical grids, which cover the eastern and western United States. An EPA map shows that most of the Texas Panhandle and parts of eastern Texas are part of the Eastern Interconnection, and the El Paso area is part of the Western Interconnection. The rest of Texas is in what is called the Texas Interconnection.
The Texas Interconnection can draw a small amount of power from other grids using direct current DC ties. There are connections to the Eastern Interconnection and the power grid in Mexico, but these connections can only transfer small amounts of power. For example, 800 MW per day can be transferred through connections to the eastern grid, and 400 MW per day can be transferred through the Mexican grid.
The primary driver for Texas to have its own grid was to be removed from the federal government's purview. Texas power companies agreed not to sell power outside of Texas, which allowed them to avoid federal regulation. Texas is a very large state with two time zones, which means that the demand for energy is staggered. When people in East Texas wake up and turn on their lights, many people in West Texas are still asleep, so the grid is not overloaded.
Solar power and wind power in Texas have the potential to allow the state to remain an energy-exporting state over the long term. The western portion of the state has abundant open land areas with some of the greatest solar and wind potential in the US. In 2017, wind power accounted for at least 15.7% of the electricity generated in Texas.

The Electric Reliability Council of Texas (ERCOT)
ERCOT was formed in 1970 to comply with NERC requirements. It is the first independent system operator (ISO) in the United States and one of nine ISOs in North America. ERCOT works with the Texas Reliability Entity (TRE), which is one of eight regional entities within the North American Electric Reliability Corporation (NERC) that coordinate to improve the reliability of the bulk power grid.
The Texas grid is independent from the country's two other electrical grids, which cover the eastern and western United States. The entire grid is contained within Texas, and Texas power companies agreed not to sell power outside of the state, allowing them to avoid federal regulation. The Texas Interconnection is one of three minor grids in the North American power transmission grid, along with the Quebec Interconnection and the Alaska Interconnection. The two major interconnections are the Eastern Interconnection and the Western Interconnection.
The Texas grid is not subject to regulation under the Federal Power Act, as it is an intrastate grid for the purposes of that law. The deregulation of the Texas electricity market occurred in two phases: the wholesale generation market in 1995 and the rest of the sector in 1999. The 1999 deregulation was aimed at counteracting a shortage of generation capacity in the state.
In 2003, ERCOT was ordered to transition from a wholesale electric market with four large regions to a marketplace made up of more than 4,000 nodes throughout the state. This undertaking, called the Nodal Project, aimed to improve the efficiency of the grid by having more specific information for different locations. In 2005, Texas became the top wind-producing state in the U.S., and in 2007, ERCOT maintained this lead by producing more than 8,000 megawatts (MW) of wind power.

Texas' energy market is deregulated
Texas has a deregulated energy market, which means that the government does not intervene, and the market drives competition among providers. The state's energy market is unique in several ways. Firstly, it is the most populous state with a deregulated energy market, with over 29 million people. Secondly, Texas does not have a government-backed utility, allowing for a wider range of energy plans and types. Thirdly, Texas has its own energy-governing agencies, the Electric Reliability Council of Texas (ERCOT) and the Public Utility Commission of Texas (PUCT). ERCOT manages the state's power grid, which covers around 90% of the state's electrical load, while PUCT oversees electricity providers, ensuring compliance with regulations.
The Texas energy market became deregulated in stages, starting with the passage of Senate Bill 373 in 1995, followed by Senate Bill 7 in 1999, and the granting of independence to ERCOT in 2002. This process allowed for the separation of electricity generation and distribution, giving customers the freedom to choose their energy suppliers.
One of the goals of deregulation is to increase competition and provide consumers with more choices. In the first decade of retail electric deregulation in Texas, the market experienced significant growth in the number of firms active and the variety of products offered. For example, in the Dallas-Fort Worth area, the number of retail electric providers offering price plans to residential customers increased from 10 in 2002 to 45 by the end of 2012.
However, there are also risks associated with a deregulated energy market, such as price volatility, misleading marketing practices, and reduced consumer protection. Additionally, in some cases, deregulation can lead to infrastructure issues, as seen during Texas' 2021 Winter Storm crisis, when wholesale electricity prices surged by up to 10,000% in some areas.
Texas' energy market is also unique because it is disconnected from other intercontinental grids. The state has its own electrical grid, known as the Texas Interconnection, which is one of three minor grids in the North American power transmission system. This grid is managed by ERCOT and is maintained separately from other states' grids for political reasons, allowing Texas to avoid federal regulations.

Texas' power grid is decentralized
Texas has a decentralized power grid, which is managed by the Electric Reliability Council of Texas (ERCOT). ERCOT is the first independent system operator (ISO) in the United States and one of nine ISOs in North America. The Texas Interconnection, as it is called, is a wide-area synchronous grid that covers most of the state of Texas.
The Texas power grid is independent from the country's two other electrical grids, which cover the eastern and western United States. The Texas grid is maintained as a separate grid for political, rather than technical reasons. By not crossing state lines, the Texas power grid is not subject to federal regulation by the Federal Energy Regulatory Commission (FERC). This allows Texas power companies to avoid federal laws that dictate how energy can be bought, sold, and distributed.
The Texas grid is tied to the Eastern Interconnection with two DC ties, and to the Western Interconnection and the Mexican grid with DC ties. However, these ties only allow for the transfer of small amounts of power. For example, 800 MW of power can be transferred per day through connections to the eastern grid, and 400 MW per day through the Mexican grid.
Texas's decision to maintain a separate power grid has led to energy problems in the state. In February 2021, a massive ice storm hit Texas, causing a surge in demand that surpassed the state's capacity to generate electricity. This resulted in rolling blackouts that affected over 4 million people and led to the deaths of 246 people, most of whom died from the cold.
Despite weatherization efforts, the Texas power grid remains vulnerable. ERCOT's January 2025 Monthly Outlook for Resource Adequacy (MORA) reported an 80% risk of rolling blackouts if a winter storm similar to Uri were to hit Texas again.

Texas' power grid is separate from the two larger national grids
Texas has its own power grid, separate from the two larger national grids in the United States. This means that Texas and its grid operator, the Electric Reliability Council of Texas (ERCOT), are not under the jurisdiction of the Federal Energy Regulatory Commission (FERC). The Texas grid is also referred to as the Texas Interconnection, which covers most of the state.
The Texas power grid is independent for historical and political reasons. In 1935, President Franklin D. Roosevelt signed the Federal Power Act, which gave the federal government the authority to regulate power companies that engaged in interstate commerce. Texas power companies agreed not to sell power outside of the state, allowing them to avoid federal regulation. This decision was influenced by the desire of Texas power companies to avoid federal laws dictating how energy was bought, sold, and distributed, as well as the state's abundant natural resources for fuel.
The Electric Reliability Council of Texas (ERCOT) manages the flow of electric power on the Texas Interconnection, supplying power to approximately 26 million customers, which represents about 90% of the state's electric load. ERCOT is unique in that it serves as both a balancing authority and an interconnection. However, because ERCOT is an interconnection itself, it cannot manage the transfer of electricity from other balancing authorities. This means that Texas cannot borrow power from other states' grids during times of high demand or crises, such as the 2021 winter storm that led to deadly power outages.
While there have been discussions and proposals to connect the Texas grid to the surrounding states, as of February 2022, there were no plans to change the status of the grid.
