ERCOT LMP by Bus
ERCOT real-time LMP at every electrical bus, set by SCED roughly every five minutes: the finest public view of where Texas prices differ.
About this data
Each row is the real-time price at one ERCOT electrical bus for one SCED interval, a finer grid than the settlement points. It is the most detailed public view of where ERCOT prices separated across the network. A spread between two buses shows that prices diverged, not which constraint drove it. People use it for bus-level ranking, price history and basis analysis.
What people use it for
- Look up the real-time price at a specific bus
- Rank buses by price over an interval or a day
- Analyze basis between buses
