How SB 6 Is Shifting the Power Balance in Texas Energy

What Is Senate Bill 6?

Senate Bill 6 (SB 6), passed in June 2025, marks a major change for the Texas electricity market. The law was created in response to repeated threats to grid reliability caused by severe weather and growing demand. Explosive growth in data centers, crypto mining, and other large commercial facilities has stretched the state’s electric grid to its limit. Lawmakers saw these trends as a risk: the increasing size and number of heavy electricity users could put residential and small business customers at risk during periods of high demand or emergency. SB 6 gives grid operators—specifically ERCOT—powerful new tools to protect everyday Texans when electricity supplies are tight.

How SB 6 Expands ERCOT’s Authority

With SB 6, ERCOT (the Electric Reliability Council of Texas) now holds stronger oversight over the state’s largest power consumers:

• Targets large users: Industrial facilities and data centers using 75MW or more are directly affected.

• Emergency disconnection: ERCOT can require large users to disconnect from the grid in emergencies, prioritizing homes and small businesses when electricity is scarce.

• Wider oversight: ERCOT now oversees private supply deals and self-generation (such as on-site generators) used by big customers to avoid grid disruptions.

• New requirements: Large commercial users face stricter standards for operations, timely bill payments, and detailed reporting on energy use and emergency plans.

These rules mean that Texas’s biggest electricity users can no longer operate with the same autonomy during a crisis—they must coordinate closely with ERCOT or risk being shut down to safeguard the grid.

How SB 6 Protects Texas Households

The primary purpose of SB 6 is to protect everyday consumers—those least able to weather power outages—when supply runs short. Here’s how it works:

• Prioritization: In a grid emergency, large industrial users are the first to be curtailed, while residential and small business customers are given priority.

• Reduced blackout risk: By addressing large users first, SB 6 lowers the risk of rolling blackouts for most Texans.

• Faster emergency action: ERCOT can quickly intervene, making the grid more responsive when conditions change fast.

This means that, even as Texas’s energy landscape becomes more complex, homes and local businesses have an improved shield against power interruptions caused by sudden spikes in demand or weather extremes.

What SB 6 Means for Big Energy Users and Grid Operations

SB 6 isn’t just about protecting households; it fundamentally changes how Texas coordinates grid stability as industrial growth accelerates.

For Large Users:

• Compliance: Companies using 75MW+ must be ready for potential curtailment orders and prove they can adjust their energy use quickly.

• Contracts and planning: Many will need to revisit contracts, invest in flexible operations, or build more on-site generation to handle emergency cutoffs.

• Reporting: Documenting energy use and emergency procedures now matters more than ever.

For Grid Operations:

• Greater oversight: ERCOT’s stronger hand helps manage the risk associated with huge new loads from data centers and crypto operations.

• Balancing act: Regulators must still encourage industrial growth while preventing it from threatening grid reliability.

• Collaboration: Ongoing coordination among grid operators, large users, and lawmakers is necessary to keep the system resilient.

Texas still faces big challenges: aging transmission lines, heavy congestion on parts of the grid, and relentless new demand from big tech and industry. SB 6 is a step toward managing these issues, but the situation will continue evolving.

Key Takeaways for Texas Electricity Consumers

• Stronger consumer protections: SB 6 puts everyday Texans first when grid emergencies hit, aiming to keep homes powered even as grid stress increases.

• Adapting to change: With technology and industry demanding more energy, staying informed about legislative updates is crucial—they can impact reliability, rates, and the future of your service.

• Opportunity for savings: Understanding these changes can help you pick better plans and make use of new incentives as the market adapts.
