Live ERCOT Grid Status & Texas Fuel Mix

Below are live visuals for Texas grid conditions. Data is pulled every 5 minutes from ERCOT dashboards and includes grid health indicators plus generation share by fuel type (wind, solar, nuclear, natural gas, and others). You can also explore historical intraday behavior using Any Day starting from March 2026, when data collection began.

This page is for informational purposes only. The landscape animation reacts to live values: more wind means faster turbine rotation, and plant effects (like smoke/steam) change with output. You will also find a historical fuel mix chart showing how renewable generation has increased significantly over the last decade.

Frequently Asked Questions

These notes explain how to read the live ERCOT grid visuals, reserve conditions, and fuel mix behavior.

Where does this data come from?
This data comes directly from the ERCOT public API. To keep everything accurate and live, our systems ingest raw values every 5 minutes for current conditions. We use these real-time dashboards for current status and official yearly data for historical trends.
What are Operating Reserves and why do they matter?
Think of Operating Reserves as the grid safety cushion. It is extra power available right now that is not being used, but is ready to respond if a plant fails or demand spikes. Depending on the reserve level, ERCOT moves through different condition stages:
  • Normal Conditions: Grid is healthy (typically above 3,000 MW).
  • Advisory / Watch: Reserves are tightening and ERCOT is monitoring closely.
  • EEA Level 1: Reserves below 2,500 MW; ERCOT brings all available generation online.
  • EEA Level 2: Reserves below 2,000 MW; ERCOT may reduce power to large industrial loads.
  • EEA Level 3: Reserves below 1,500 MW; controlled rolling outages can become necessary to avoid total grid collapse.
What is the difference between "Power in Use" and "Total Available"?
This is the balance of demand vs. supply. Power in Use is real-time consumption (what Texans are currently using). Total Available is the maximum power currently-online plants can produce.
What is Power Storage and why is the value sometimes negative?
Power Storage represents utility-scale battery fleets. When the value is negative, batteries are charging (taking power from the grid for later use). When it is positive, batteries are discharging (sending power back to the grid). ERCOT often uses storage around sunrise and sunset transitions, and during high-stress periods, to quickly stabilize supply and demand.
