7 Surprising Facts About the Texas Electricity Grid That Will Shock You

Think you know everything about how your lights stay on? Texas electricity is unlike anywhere else in America. From a rebellious history to record-breaking renewable energy, here are seven facts that might just surprise you.

1. Texas Has Its Own Power Grid (And It's on Purpose)

While the rest of the country runs on two major power grids—the Eastern and Western Interconnections—Texas marches to the beat of its own drum with the Texas Interconnection.

Why? It all goes back to the 1930s. Texas utilities realized that if they kept electricity generation and transmission entirely within state borders, they could avoid federal regulation. No crossing state lines means no Federal Energy Regulatory Commission (FERC) oversight.

This independence is managed by ERCOT (Electric Reliability Council of Texas), which became the first independent system operator in the United States.

2. We Power More People Than Many Countries

The Texas grid serves more than 27 million people—about 90% of the state's electricity demand. To put that in perspective, our annual electricity consumption is comparable to entire nations like Great Britain and Spain.

ERCOT manages an impressive infrastructure:

• 54,000+ miles of transmission lines
• 1,200+ generation units
• Enough capacity to power one of the world's largest economies

3. The Famous "Midnight Connection" Incident

Here's a piece of Texas electricity lore that sounds like it belongs in a movie.

On May 4, 1976, a utility company called Central Southwest Holdings pulled off what became known as the "Midnight Connection." Under cover of darkness, they briefly connected the Texas grid to Oklahoma.

Their goal? Force the issue of whether this would trigger federal regulation. Lawsuits flew, but ultimately courts ruled that the brief connection wasn't enough to bring FERC into the picture. Texas remained independent, and the legend of the Midnight Connection was born.

4. Texas Is America's Wind Energy Champion

For a state famous for oil and gas, Texas has quietly become the nation's leading producer of wind electricity. We generate more wind power than any other state—and it's not even close.

Recent developments are even more impressive:

• ERCOT had 11 GW of grid batteries by 2025 (up from just 2 GW in 2022)
• Texas expects to add another 5 GW of battery storage this year
• The famous "duck curve" is reshaping how we think about energy, with solar creating abundant midday supply

5. You Have More Than 100 Electricity Providers to Choose From

Thanks to deregulation in 2002, Texans in competitive areas can choose their electricity provider. The Texas electricity market is now the largest deregulated energy market in the United States, serving over 26 million consumers.

Consider this growth:

• 2002: Dallas-Fort Worth had 10 providers with 11 price plans
• 2012: 45 providers with 258 price plans
• Today: 100+ retail electricity providers competing for your business

That competition means 75% of ERCOT's load is competitively served—making Texas the most comprehensively deregulated market without a government-backed utility in the nation.

6. ERCOT Just Launched a Game-Changing Technology

On December 5, 2025, ERCOT announced a major milestone: the successful launch of Real-Time Co-optimization Plus Batteries (RTC+B).

This technology allows the grid to optimize electricity generation and battery storage in real-time, making the entire system more efficient and reliable. It's a significant step forward for grid stability, especially as Texas continues adding renewable energy sources.

---

7. We Run an "Energy-Only" Market

Unlike other electricity markets that pay generators to maintain extra capacity "just in case," Texas operates as an energy-only market. Power generators get paid only for the electricity they actually produce and sell.

This approach encourages efficiency and keeps costs competitive. It also means Texas electricity prices can spike during extreme weather when demand outpaces supply—which is why shopping for the right electricity plan matters more here than almost anywhere else.

What This Means for Your Electric Bill

Understanding how unique Texas electricity is can help you make smarter choices:

• Shop around: With 100+ providers, competition works in your favor
• Consider renewable plans: Texas's wind and solar abundance means competitive green energy rates
• Watch peak hours: Our energy-only market means prices can vary significantly by time of day
