DC Tie Flows is a graphical representation of the four non-synchronous transmission interconnections (Direct Current Ties) between ERCOT and non-ERCOT electric power systems.
The times and the Last Updated timestamp displayed in this dashboard are presented in Central Daylight Time (CDT) (UTC -5). If you are viewing from another time zone, the times are not automatically converted to yours at this time. This is a known issue that ERCOT is working to correct.
This dashboard provides a view of recent DC Tie activity at four interconnections. A negative number in the DC Tie Flows indicates an import to the ERCOT region; a positive number indicates an export from the ERCOT region.
The following report provides similar data points, but since the minimum data refresh rate of this dashboard is every 5 minutes, the data in the reports may not provide a one-to-one match with the values currently displayed in the dashboard:
