What this shows
The live mix
ERCOT's latest generation by fuel, the same measure ERCOT's own fuel mix report publishes, in megawatts and as a share of the total.
How the renewable share is measured
Each month's share is that fuel's generation divided by all generation, battery charging excluded, from ERCOT's Fuel Mix Report. Months the report has not yet published come from ERCOT's 5-minute fuel mix and are marked provisional until it does.
Why the mix moves through the day
Solar rises to an afternoon peak and drops away at sunset, wind often strengthens overnight, and gas and battery storage fill the gap as demand peaks in the evening.
What people ask
What is ERCOT's largest source of electricity?
Over a year, natural gas. In individual hours wind or solar can lead. The panel above shows the current leader and its share.
What share of ERCOT's power comes from wind and solar?
The monthly table above gives wind, solar and their combined share for every recent month, and the yearly table every full year since 2007. The share swings with the seasons: spring is windiest, and summer brings the most solar.
Does storage count as generation?
Only while batteries discharge. Charging draws power from the grid, so it shows up as demand rather than as negative generation.
