Texas's unique power grid
Texas has a unique power grid system that operates independently from the rest of the United States. This grid is known as the Texas Interconnection and is managed by the Electric Reliability Council of Texas (ERCOT). The Texas Interconnection is one of three minor grids in the North American power transmission grid, alongside the Quebec Interconnection and the Alaska Interconnection. The other two major interconnections are the Eastern Interconnection and the Western Interconnection.
The Texas grid's independence from federal regulation has its roots in the early 20th century, when small generating plants began to spring up across the state, bringing electric light to cities. During World War I, these utilities started to link themselves together, and these connections expanded during World War II with the formation of the Texas Interconnected System. This system allowed utilities to connect to the large dams on Texas rivers and provide electricity to support the war effort. However, a key priority for the Texas Interconnected System was to remain free from federal regulation. In 1935, President Franklin D. Roosevelt signed the Federal Power Act, which provided for oversight of interstate electricity sales, but Texas avoided this regulation by not crossing state lines with its power grid.
The Electric Reliability Council of Texas (ERCOT) was formed in 1970 following a major blackout in the Northeast in 1965. 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 a membership-based nonprofit corporation, governed by a board of directors and subject to oversight by the Public Utility Commission of Texas (PUC) and the Texas Legislature. Its members include consumers, electric cooperatives, generators, power marketers, and various electric utilities.
Texas's power grid has faced challenges, particularly during extreme weather events. In 2021, a winter storm caused widespread outages as natural gas infrastructure and wind turbines froze. This crisis highlighted the need for improvements to the grid's reliability and resilience. Since then, efforts have been made to winterize infrastructure, diversify energy sources, implement advanced grid monitoring, and develop energy storage solutions.
Texas leads the nation in energy production and has abundant renewable energy resources. Wind power in Texas consists of over 40 wind farms, with a total nameplate capacity of over 30,000 MW as of 2020. Texas also has significant solar energy potential due to its many sunny days and is among the leading states in solar energy generation. The state also has geothermal resources suitable for power generation in eastern and southern Texas.

Oil and natural gas
Texas is the top oil and gas state in the US. In 2019, Texas produced 41% of the country's crude oil and 25% of its natural gas. In 2021, these figures rose to 42% and 27% respectively. Texas also has 32 petroleum refineries, the most of any state, which can process more than 5.9 million barrels of crude oil per day (32% of US refining capacity).
Texas has a unique power grid that is different from other national grids. The Texas power grid is managed by the Electric Reliability Council of Texas (ERCOT), which oversees the flow of electricity for most of the state. Texas has its own electricity grid because it is not part of the federal power grid. The federal government does not have the same authority over Texas' grid as it does over the grids in other states.
Texas has moved away from coal and towards renewable sources of energy like wind and solar power. However, oil and gas are still vital for Texas' energy industry, with many sectors of manufacturing, such as the auto industry and petrochemical and plastics production, dependent on them.

Wind power
Texas has a unique power grid that relies on an abundance of natural resources for its energy supply. Wind power is a significant component of Texas's energy mix, with the state producing the most wind power of any US state. In 2017, wind power accounted for at least 15.7% of the electricity generated in Texas, and this figure has continued to grow. Texas is the national leader in wind power generation, comprising about 28% of national wind-powered electrical production in 2019 and 26% in 2021.
The development of wind power in Texas has been driven by several factors. Firstly, the state has favourable wind resources and land availability, with many areas possessing wind conditions suitable for wind power generation. Additionally, Texas has set targets for renewable energy, and the cost efficiency of developing and operating wind farms has made it a profitable enterprise for landowners and wind farm operators. Farmers can lease their land to wind developers, creating a new revenue stream without impacting traditional farming practices.
However, wind power in Texas also faces several challenges. One issue is the transmission capacity of the state's grid, which has struggled to accommodate the surplus electricity generated by wind turbines. Additionally, opponents of renewable energy argue that wind power is unreliable, pointing to instances like the blackouts during Winter Storm Uri in 2021. The state's growing hostility towards renewables is influenced by the powerful fossil fuel industry, with organizations like the Texas Public Policy Foundation playing a significant role in promoting fossil fuels over renewable sources.

Coal
Texas is the nation's largest coal consumer, with almost all of the coal used to fuel the state's power plants. Texas has long been a leader in the energy industry, with its abundance of fossil fuels and renewable sources generating electricity for the state and making substantial contributions to the Texas economy.
In 2022, Texas coal-fired power plants had an installed capacity of nearly 20,000 megawatts of electricity, with coal-fired electricity generation accounting for 16.6% of the state's energy production that year. However, the use of coal as a power source for electricity generation has been declining in Texas. In 2021, coal generated 88.8 million megawatt-hours of energy, a significant decrease from the 138 million megawatt-hours produced a decade earlier in 2012. This decline is due in part to the increasing uneconomical nature of coal as a fuel source, with costs associated with compliance with federal environmental regulations like the Clean Air Act. As coal-fired plants have closed, many have been converted to natural gas plants.
Despite the overall decline in coal industry employment, Texas had nearly 7,000 coal-related jobs in 2022, including coal-fuel and coal-power generation occupations. Coal mining and coal mining support activities contributed approximately $659.5 million to Texas's gross domestic product in 2021. Coal mining jobs located in rural parts of the state provide economic opportunities to communities in need.
