🏭 ERCOT, Oncor & you: Part 2

Part 1 outlined ERCOT’s role in maintaining a stable grid.

  • Let’s take a closer look at what the grid actually is.

Why it matters: Knowing the different pieces of the Texas Electricity Market can help you understand where to turn for information during an outage.

👉 It starts with power generation —> hundreds of power plants in Texas produce more than twice the electricity of the next highest state in the U.S, Florida.

  • Luminant’s natural gas power plant in Forney or the Comanche Peak Nuclear Power plant in Somervell County are two examples.

👉 The grid is then made up of transmission and distribution lines, substations and transformers.

  • Transmission lines are the large high voltage steel towers you see in green belt areas.
  • Distribution lines are lower voltage lines that deliver the electricity to your house.

👉 Companies that own and operate these lines are called Transmission and Distribution Utilities (TDUs).

  • Oncor is the largest TDU in North Texas.
  • Utility co-ops like CoServ also operate throughout North Texas.

👉 Your TDU owns and monitors your meter.

  • They are the ones you call when your power goes out.

✅ For your Smart Homeowner list

  • Make sure you know who your TDU is, so you know where to turn for information during an outage or in the event of a downed power line or transformer.
