Overview

This is the live operational view of where power is actually coming from at any moment, the faster companion to the settlement-grade Fuel Mix Report. It lets operators, traders, and researchers watch the resource mix shift in near real time, track renewable ramps and gas response intraday, and see how generation composition moves with load and prices. The official upstream source is ERCOT report NP6-788-CD (Fuel Mix Report). The SQL agent queries this through the unified `ercot_fuel_mix` view (quality='live') rather than this table directly.

Query contract
Select one exact event_time snapshot. Each fuel column is the ERCOT-wide net output for that interval.
Analysis rules
For a current fuel mix, use every fuel column from the same latest event_time; do not combine values from different snapshots.Calculate shares against the algebraic sum of all returned fuel columns at that snapshot.
Interpretation
storage_mw is net fleet output: positive is discharging into the grid and negative is charging from the grid.A single snapshot supports the observed mix and storage direction, but not a ramp, daily pattern, cause, or forecast narrative.
