The Electric Reliability Council of Texas (ERCOT)
Texas's electric grid is not connected to the rest of the national grid. The Texas Legislature and the Public Utility Commission of Texas (PUC) have primary jurisdiction over ERCOT. ERCOT was created in 1970 to comply with NERC requirements and was the successor to the Texas Interconnected System (TIS). TIS was formed at the beginning of World War II to provide power for aluminium smelting companies located along the Gulf Coast and to support the war effort. Recognising the reliability advantages of remaining interconnected, TIS members continued to operate and develop the interconnected grid even after the war.
In 1981, ERCOT became the central operating coordinator for Texas electricity. Later, in 1996, ERCOT became the original electric utility industry Independent System Operator (ISO) in the U.S. 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 also removed the limits on rate increases, leading to a 64% increase in residential electricity rates between 1999 and 2007.
In September 2003, the state legislature and PUC ordered ERCOT 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 throughout the state. In 2005, Texas became the top wind-producing state in the U.S., maintaining this lead in 2007 after producing more than 8,000 megawatts (MW) of wind power. In December 2010, ERCOT’s wind output reached a record high of 25.8 percent of the company’s load (9,528 MW).

Public Utility Commission of Texas (PUC)
The Public Utility Commission of Texas (PUC) is a state agency that regulates the state's electric, telecommunication, and water and sewer utilities. The PUC was established in 1975 when the Texas Legislature enacted the Public Utility Regulatory Act (PURA), charging the agency with providing statewide regulation of the rates and services of electric and telecommunications utilities. The PUC's mission is to "protect customers, foster competition, and promote high-quality infrastructure".
The PUC is headquartered in the William B. Travis State Office Building at 1701 North Congress in Austin. It is governed by a five-member commission, appointed by the Governor of Texas. The commission regulates the rates and services of transmission and distribution utilities where there is competition, investor-owned electric utilities where there is no competition, and incumbent local exchange companies that have not elected incentive regulation.
Over the years, the PUC's mission and focus have shifted from upfront regulation of rates and services to oversight of competitive markets and compliance enforcement of statutes and rules for the electric and telecommunication industries. This shift has been driven by the introduction of competition in the local and long-distance telecommunications markets and the wholesale and retail electric markets. The PUC played a key role in overseeing the transition to a competitive energy market, ensuring that customers received the benefits of competition.
The PUC has also been involved in proposing changes to the state's electricity market to incentivize the development of new gas-fired plants or extend the lifespan of existing ones. In the wake of the February 2021 North American winter storm, the PUC faced lawsuits alleging that its actions led to a spike in electricity prices. However, the Supreme Court of Texas ruled in 2024 that the PUC acted within its authority as a state agency and was immune from suit.

Deregulation and consumer choice
Deregulation of the Texas electricity market began in 1995 with Senate Bill 373, followed by Senate Bill 7 in 1999, and the independence granted to the Electric Reliability Council of Texas (ERCOT) in 2002. These milestones allowed for the separation of electricity generation and distribution, creating a competitive landscape with numerous electricity providers and plan options for consumers.
The Texas electricity market is unique in its comprehensive deregulation, lacking a government-backed utility, which has resulted in a diverse range of energy plans and types. This deregulated market gives consumers the freedom to choose their energy suppliers and plans based on their specific needs and budgets. The competition among providers is intended to drive down prices, increase plan options, and improve customer service.
In a deregulated market, consumers can shop for plans, compare prices, and select a retail electric provider (REP) that suits their requirements. This freedom of choice allows customers to tailor their electricity choices to their budgets and lifestyles. For instance, consumers can choose a provider based on their renewable energy portfolio, enabling them to support green energy sources.
However, it is important to note that deregulation also comes with certain risks. Consumers in deregulated markets may experience price volatility, misleading marketing practices, and reduced consumer protection. Additionally, as seen in Texas' 2021 Winter Storm crisis, deregulation can sometimes lead to infrastructure issues.
Despite these challenges, the Public Utility Commission of Texas (PUCT) is the state agency responsible for regulating and overseeing the Texas electricity market, including ERCOT. PUCT ensures compliance with regulations, while ERCOT manages the state's power grid and sets electricity prices based on a competitive wholesale bulk-power market.

Weatherization of power infrastructure
In Texas, the Electric Reliability Council of Texas (ERCOT) manages the flow of electric power to over 27 million customers, which is about 90% of the state's electric load. ERCOT is a membership-based nonprofit corporation, overseen by the Public Utility Commission of Texas and the Texas Legislature.
In February 2021, Texas experienced a severe winter storm that disrupted the state's power infrastructure. The storm caused power outages across the state, leading to millions of homes and businesses losing power. This event highlighted the need for weatherization of the power infrastructure in Texas to prevent similar incidents from occurring in the future.
Following the 2021 winter storm, the Texas Legislature directed the Public Utility Commission to ensure that power generators prepared their infrastructure for extreme weather. As a result, new weatherization standards for energy facilities were approved in May 2021. The Public Utility Commission was responsible for creating and implementing requirements for power plants, while the Texas Railroad Commission, the state's oil and gas regulator, developed requirements for natural gas facilities. These new rules aimed to address the shortcomings exposed by the winter storm and improve the resilience of the power infrastructure in Texas.
The weatherization standards require power plants and natural gas facilities to be able to continue operating during extreme weather events, such as freezing temperatures. This includes insulating and replacing water pipes, winterizing wind turbines, and using heat tracing to prevent pressure sensors from freezing at natural gas and nuclear power plants. While the majority of thermal power plants stayed online during the 2021 winter storm, there were still failures, and natural gas production faced significant challenges.
The Texas power grid remains vulnerable to extreme weather events, and there are concerns about its resilience. While the grid has seen improvements since the 2021 winter storm, there are still critical gaps in weatherization and infrastructure resilience. The increasing reliance on renewable energy sources, such as wind and solar power, also adds complexity to the energy mix, and thermal power reliability becomes crucial.
To enhance the weatherization of the power infrastructure in Texas, improved enforcement of weatherization standards, incentives for thermal power plant development, and enhanced demand-response programs are recommended. These measures aim to ensure that the power infrastructure can withstand extreme weather events and maintain reliable power supply to Texas residents.

Natural gas industry oversight by the Texas Railroad Commission (RRC)
The Electric Reliability Council of Texas (ERCOT) manages the flow of electric power to over 27 million customers in the state, representing about 90% of Texas's electric load. ERCOT is subject to oversight by the Public Utility Commission of Texas and the Texas Legislature.
The Railroad Commission of Texas (RRC) is the state agency that regulates the oil and natural gas industries, natural gas utilities, pipeline safety, and the natural gas and hazardous liquid pipeline industry. The RRC, through its Oil and Gas Division, regulates the exploration, production, and transportation of oil and natural gas in Texas. The division accomplishes these goals by implementing permitting and reporting requirements, conducting field inspections and testing programs, and monitoring industry activities. It also has programs to remediate abandoned wells and sites through fees and taxes paid by the industry.
The RRC is responsible for research and education to promote the use of liquefied petroleum gas as an alternative fuel. It is the oldest regulatory agency in Texas and was established in 1891 to regulate the railroad industry. The commission began to regulate oil production in the early 20th century as the industry started booming in Texas. By the mid-1930s, Texas dominated world markets, leading to a global oil price plummet. This prompted the federal government to grant the RRC the responsibility to impose limits on oil production at each well.
The RRC has an annual budget of $79 million and focuses on oil, gas, mining, propane, and pipelines, setting monthly production quotas. Waste Haulers can submit various forms online to the RRC using the Railroad Commission State Tracking and Reporting (LoneSTAR) portal. The RRC will continue to accept hard copy filings of these forms until July 1, 2025, after which they must be filed online through LoneSTAR.
