How much requested large load in ERCOT reaches approval to energize, and how much is actually drawn?

Requested capacity, approval to energize and observed consumption are different quantities. They are shown side by side from a single source report, never combined into one figure. ERCOT publishes several peak definitions; each is kept separately. ERCOT does not publish these stages by request cohort, so this is a stock view, not a cohort conversion.

From Electric Reliability Council of Texas (ERCOT), report dated 13 Mar 2026.

Requested

238,630 MW

Approved to energize

9,042 MW

Observed peak consumption

5,768 MW · observed energized 3,883 MW · peak nonsimultaneous 3,801 MW · peak simultaneous

All bars share one linear scale from zero. Where the source publishes several definitions of a stage, each is shown as its own bar.
