Overview
ERCOT's five-minute real-time system lambda, the system-wide marginal energy component of SCED LMP. For a settlement point or electrical bus in the same SCED interval, LMP minus system lambda is the point's congestion component; ERCOT LMP has no marginal-loss component. This supports point-level congestion rankings and history when joined interval by interval to real-time LMP. It does not identify which binding constraint affected a point without shift-factor or other direct attribution evidence.
