Texas Power Grid Resilience: What's Changed Since the 2021 Ice Storm?

Grid Performance During Winter Storms

• 💡 Energy experts express high confidence that the Texas grid will perform well during the current storm.
• ⚡ The current storm is not expected to last as long as the deadly 2021 storm.

Monitoring Grid Conditions

• 📊 Live grid conditions are monitored via ERCOT's website, focusing on supply and demand of electricity.
• ⚠️ Issues arise when the supply and demand lines get too close, indicated by dropping reserve electricity levels below 3,000 megawatts.
• 📈 Real-time electricity prices, shown on a state map, can indicate localized outages and rising costs if they turn yellow, orange, or red.

Potential for Localized Outages

• ❄️ Experts anticipate that any power outages will likely be localized, caused by ice accumulation on power lines or falling tree limbs.
• 🌳 Utility companies like Oncor have been actively clearing vegetation from power lines to mitigate these risks.
• 🔍 ERCOT's website provides live, updated information that can be monitored online, especially over the next 72 hours.
