Predicting the 630__B Constraint With Transmission Impacts in ERCOT
Over the last seven days, the Enverus ERCOT P&R forecast has accurately predicted the 630__B constraint (KLNSW-HHSTH 138 kv with contingency DSALKLN5) in ERCOT. While it is fundamentally driven by high wind and solar generation, there were two transmission outages responsible for increasing flow on the constraint by 50%, while other longer term transmission outages also had a smaller impact on the same constraint.
