Today, over 85% of Texas homeowners have the freedom to shop for their own electricity plans, compare rates, and choose their retail providers. This system of consumer choice is widely known as retail electric deregulation.
However, the competitive retail market we navigate today did not happen overnight. It was forged through decades of rapid municipal electrification, grid independence, and sweeping legislative changes designed to break up utility monopolies.
In this guide, we explore the history of energy deregulation in Texas, look at the milestones that created ERCOT, and explain how the market structure directly benefits modern consumers.
The Monolithic Era (1880s – 1970s)
The first electricity generation facility in Texas was established in Galveston in the early 1880s. Over the next half-century, municipal power stations sprouted across major cities, fueled by coal, natural gas, and hydroelectric projects.
During this era, electricity was managed as a regulated monopoly:
- A single utility company owned the generation plants, transmission lines, and the billing relationship with the customer.
- Individual cities regulated these utilities, setting local rates without any state-level coordination.
- Consumers had zero choices; you paid whatever rate your local utility set.
The Birth of ERCOT and PURA (1970 – 1975)
As consumption boomed after World War II, the state needed a unified grid structure. In 1970, the Electric Reliability Council of Texas (ERCOT) was formed to coordinate power transmission and maintain grid reliability.
To bring order to fragmented municipal rate structures, the Texas Legislature passed the Public Utility Regulatory Act (PURA) in 1975. PURA transferred rate-setting authority from individual cities to a newly created state agency: the Public Utility Commission of Texas (PUCT).
While PURA consolidated regulatory control, it did not solve a growing economic problem: building new power plants was expensive, and regulated utility rates began to rise steadily.
Paving the Way for Choice (1995 – 2002)
By the mid-1990s, lawmakers realized that competition, rather than state regulation, was the key to lowering rates.
Senate Bill 7 (1999)
The watershed moment came in 1999 when Governor George W. Bush signed Senate Bill 7. This bill mandated the restructuring of the Texas electric utility industry to introduce retail competition, setting a launch date of January 1, 2002.
Under SB 7, the old vertically integrated utility monopolies were forced to split into three separate, independent entities:
Deregulation Today: Choosing Your Plan
Since the full rollout in 2002, the Texas competitive market has grown to feature over 100 REPs competing for your business. This competition has driven the introduction of innovative plans:
- Green Renewable Plans: Empowering consumers to support 100% solar and wind generation.
- Smart Home Integrations: Offering discounted rates for smart thermostat integration and EV charging.
- Prepaid Options: Allowing consumers to bypass traditional credit check requirements.
Timeline: How Texas Got to Deregulation
- Early 1880s: The first electricity generation facility in Texas is established in Galveston.
- 1970: The Electric Reliability Council of Texas (ERCOT) is formed to coordinate power transmission and maintain grid reliability.
- 1975: The Public Utility Regulatory Act (PURA) moves rate-setting authority from individual cities to the newly created Public Utility Commission of Texas (PUCT).
- 1999: Governor George W. Bush signs Senate Bill 7, mandating retail competition and splitting vertically integrated utilities into generation, transmission and distribution (TDUs), and retail electric providers (REPs).
- January 1, 2002: The competitive retail market officially launches.
- Today: Over 85% of Texas homeowners can choose their provider, with more than 100 REPs competing on price, renewable options, and smart home plans.
What Deregulation Did Not Change
Consumer choice applies only to the retail side of your bill. Three pillars of the old system remain intact:
- TDUs are still regional monopolies. The wires and poles are maintained by regulated transmission and distribution utilities with PUCT-approved flat pass-through delivery fees — you cannot shop for your wires company.
- The PUCT still oversees the market. The agency created by PURA in 1975 continues to regulate the non-competitive side of the industry.
- ERCOT still runs the grid. The council formed in 1970 coordinates power transmission and maintains grid reliability for the state.
Understanding this split explains your modern bill: the delivery charges come from a regulated monopoly, while the energy charges come from the competitive market you are free to shop.

Frequently Asked Questions
When did Texas deregulate its electricity market?
Texas deregulation was set in motion when Governor George W. Bush signed Senate Bill 7 in 1999, mandating the restructuring of the state's electric utility industry. The competitive retail market officially launched on January 1, 2002, splitting the old utility monopolies into generation, transmission and distribution (TDUs), and retail electric providers (REPs).
Which parts of the Texas electricity market are regulated?
Under the post-SB 7 structure, power generation and retail providers (100+ active REPs) compete in a free market, while transmission and distribution utilities remain regional regulated monopolies with PUCT-approved delivery fees. The Public Utility Commission of Texas, created by the Public Utility Regulatory Act (PURA) in 1975, oversees the regulated side, and ERCOT — formed in 1970 — coordinates grid reliability.
Can all Texans choose their electricity provider?
Today, over 85% of Texas homeowners can shop for their own electricity plans and choose their retail provider. That choice has produced green renewable plans, smart home integrations, and prepaid options that bypass traditional credit checks.
