Oncor Electric Delivery Company is the largest utility provider in Texas
Oncor Electric Delivery Company is one of the largest electric utility companies in Texas, along with Centerpoint Energy, which delivers electricity to 2.2 million customers in the greater Houston area. Other utility companies in Texas include Texas-New Mexico Power (TNMP), which is the smallest provider, serving 260,000+ homes and businesses, and AEP Texas, which delivers electricity to over 1 million customers.
As a TDU, Oncor is responsible for maintaining the transmission and distribution of electricity in its service area. This includes the maintenance of poles, wires, meters, and underground cables that bring electricity from generators to homes. Oncor also reads meters and provides this information to Retail Electricity Providers (REPs). REPs are the electricity companies that consumers interact with and purchase electricity from. They handle enrollment, billing, and customer service.
Oncor Electric Delivery Company plays a crucial role in ensuring that electricity is safely and reliably delivered to the homes of over 10 million Texans. While it does not supply the electricity directly, its role as a TDU is essential in the state's electricity market, where consumers can choose their electricity provider.

Retail Electricity Providers (REPs) sell electricity to consumers
Texas has a deregulated electricity market, which means that consumers can choose their electricity provider. There are over 60 Retail Electricity Providers (REPs) in Texas, and they all compete to offer consumers a variety of electricity plans to choose from.
REPs are companies that sell electricity to customers. They purchase electricity from power generators and package it into various plans, which they then sell to consumers. REPs are also responsible for managing customer service, billing, and other customer-facing tasks.
REPs are different from electricity generators, which build and maintain the power plants that feed power into the Texas electricity grid, and from TDSPs (Transmission and Distribution Service Providers), which maintain the infrastructure (like meters, wires, poles, and underground cables) that brings electricity from the generators to your home.
Some examples of REPs in Texas include Pulse Power, Texpo Energy, Cirro Energy, and Discount Power. These companies offer a range of energy plans, from prepaid electricity to fixed-rate plans, month-to-month options, green energy, and commercial electricity plans.
When choosing an REP, it is important to evaluate plan type, length, and supplier reputation to find the best plan for your needs. Additionally, due to the intense competition between REPs, it is important to be aware of potential hidden fees, contract issues, and other unexpected costs.

Transmission and Distribution Service Providers (TDSPs) maintain the infrastructure
Texas has a deregulated energy market, which means that while consumers can choose their electricity provider, they cannot choose their utility company. The largest electric utility company in Texas is Oncor, serving over 10 million Texans.
TDSPs own and operate the equipment and facilities that transmit and distribute electricity in Texas. They are regulated by the Public Utility Commission of Texas (PUCT) and are required to provide non-discriminatory access to the grid. Each entity that operates as a Transmission Service Provider (TSP) or Distribution Service Provider (DSP) within the Electricity Reliability Council of Texas (ERCOT) region must register with ERCOT. ERCOT is the governmental entity responsible for managing the Texas electricity grid and enforcing consumer protection laws.
TDSPs interested in competing in the retail market must be certified by ERCOT. They are also responsible for maintaining the transmission and distribution of electricity within their specific service areas. TDSPs include Oncor Electric Delivery Company, Centerpoint Energy Houston Electric, Texas-New Mexico Power Company, AEP Texas North Company, and AEP Texas Central Company.

Electricity Generators build and maintain power plants
In Texas, the process of electricity supply involves three key players: the electricity generators, the Retail Electricity Providers (REPs), and the Transmission and Distribution Service Providers (TDSPs). While the REPs are the electricity companies that Texas residents interact with for their electricity needs, the electricity generators are the ones that build and maintain power plants that feed power into the Texas electricity grid. This power is then sold to the REPs, who in turn sell it to commercial and residential users.
Electricity generators are responsible for constructing and operating power plants that generate electricity. These power plants, also known as power stations or generating plants, are industrial facilities designed to produce electric power. They achieve this through the use of generators, which are rotating machines that convert mechanical power into three-phase electric power. The generators are powered by various energy sources, with fossil fuels such as coal, oil, and natural gas being the most common globally. However, there is a growing trend towards low-carbon power sources such as nuclear power and renewable energy options like solar, wind, geothermal, and hydroelectric.
The amount of electricity produced by a power plant depends on its electricity generation capacity and the operational time of its individual generators. Power plants with higher generation capacities and longer operational times will generally produce more electricity. For instance, a power plant with a single generator and an electricity generation capacity of 100 Megawatts (MW) operating at full capacity for 24 hours will generate 2,400 megawatthours (MWh) of electricity. However, it is important to note that most power plants do not operate at full capacity every day, and their generation capacities may vary seasonally due to changes in temperature affecting the cooling of the generators.
In Texas, electricity generators work closely with ERCOT (Electricity Reliability Council of Texas), the governmental entity responsible for managing the state's electricity grid. ERCOT forecasts electricity needs and coordinates with generators to ensure a steady and sufficient power supply for Texas residents. This coordination is essential to keep the lights on and maintain a reliable electricity supply across the state.
