ERCOT Launches Real-Time Co-Optimization: What the New System Means for Texas Electricity Prices and Grid Reliability

As of December 5, 2025, ERCOT, the operator of Texas’s independent power grid, has rolled out one of its most significant market updates in years: Real-Time Co-Optimization (RTC). This new approach is designed to make the state’s power market more efficient, reliable, and affordable for millions of homes and businesses.​

What is Real-Time Co-Optimization—and Why Now?

RTC combines energy and crucial “ancillary services” (like frequency balancing and backup reserves) into a single, real-time bidding process, ensuring the lowest-cost resources are dispatched first. ERCOT’s leaders and independent analysts project that this change will:​

• Streamline power system operations, using advanced software and battery storage to fine-tune resource allocation.

• Increase competition, lower wholesale market inefficiencies, and pass along as much as $1 billion per year in savings to Texas consumers.​

How Will This Affect Texans’ Electricity Bills?

Initial forecasts show that residential electricity rates across Texas will remain in the 15–18¢ per kWh range into 2026. However, the enhanced efficiency and flexibility of RTC are expected to curb price spikes, especially during high-demand events like cold snaps or heatwaves. Consumers with fixed-rate plans should see the most stable benefits, but long-term competition could improve rates for everyone.​

Will Grid Reliability Improve?

ERCOT’s rollout of RTC comes alongside continued investment in solar, wind, and battery storage—a response to Texas’s explosive demand driven by population growth, data centers, and new industry. The new system should help manage these challenges by optimizing how and when different resources respond to changing demand. ERCOT’s December resource outlook reports “sufficient generation” for winter 2025 under normal conditions, though risks remain during rare severe weather events.​

What Should Texas Consumers Do?

• Compare electricity rates and plan options this winter to benefit from improved market competition.

• Monitor ERCOT and utility updates heading into winter, as RTC’s first operations will be closely watched for real-world performance.

• Consider fixed-rate electricity plans and seasonal efficiency upgrades to lock in the greatest cost stability.
