Texas Slashes Summer Blackout Risk with Solar and Battery Storage

Texas has significantly lowered the risk of summer power outages-from 16-percent last year to under 1-percent this summer-thanks to nearly 10 gigawatts of new utility-scale solar and battery storage capacity added since last year. This boost comes as the state anticipates one of its hottest summers ever. CEO Pablo Vegas of ERCOT credits these clean-energy gains for bolstering grid reliability during evening demand peaks.

Capacity Additions Fuel Resilience

Since last summer, Texans have benefited from 5,395-MW of solar, 3,821-MW of battery storage, and 253-MW of wind capacity. This infusion helps cover the critical "evening ramp" when solar production drops but demand remains high.

Out with the Old, In with the New

Despite retirements and downgrades totaling 366-MW of natural-gas capacity, grid emergency risk still plummeted. On several June days, renewables met over half of peak power demand in ERCOT's.

What's Next for Texas Energy

With around 400-GW of generation requests in the interconnection queue - 40-percent each from solar and storage?renewables continue to drive grid transformation. Yet, the state also introduced a $5-billion Energy Fund loan for new gas plants, including a 122-MW facility expected by mid-2027, as part of its capacity diversification strategy.

Long-Term Grid Planning Challenges

ERCOT must now balance a cleaner energy mix against dwindling gas reserves. Optimizing system projections and operational flexibility - such as load shifting at peak hours - will be essential to maintain reliability.

Broader Implications

Texas' success provides a real-world example that utility-scale solar and battery storage can sharply reduce blackout risk - even under extreme heat and rising demand. For grid planners nationwide, it confirms the role of renewables as not only sustainable, but also resilient energy solutions.
