ERCOT Sets Records: How Energy Storage is Shaping Texas’ Grid

Source: ERCOT

The Texas power grid is evolving rapidly, and February 2025 has already set new milestones. ERCOT (Electric Reliability Council of Texas) recently met record electricity demand while integrating an unprecedented level of renewable energy. According to Spectrum News, a combination of wind, solar, and battery storage played a critical role in maintaining grid reliability during peak usage.

Wind farms are now the second-largest power source in Texas, behind only natural gas. Along with solar farms, they accounted for a record average share of 29.8% of total electricity production in 2024, according to the latest data from energy think tank Ember (Reuters). This share is expected to grow in March as seasonal winds strengthen, further increasing wind energy’s role in the ERCOT generation mix. The rise of renewables is also helping to stabilize electricity prices by reducing reliance on costly natural gas during peak demand.

Perhaps the biggest game-changer, however, is the rapid deployment of battery storage. Batteries are increasingly stepping in when the sun sets and wind generation fluctuates, ensuring a smoother supply of electricity. Energy storage resources are already helping to mitigate price volatility and prevent grid disruptions. And the momentum is only building—by the end of 2025, Texas is set to add even more solar and battery assets, reinforcing its position as a leader in the energy transition (Latitude Media).

As Texas continues to push the boundaries of renewable energy integration, storage technologies will be essential in balancing supply and demand. The grid of the future is here, and ERCOT is proving that a cleaner, more resilient system is possible.
