Description:

ATC and TTC results are computed using power flow analysis tools. The ATCs computed honor thermal limits, contract limits, voltage limits, and test levels performed in the VAST Studies. On & Off Peak ATC calculations use the expected peak load for a given period. The effect of each transmission reservation on ATC is calculated based on the given source and sink. Sources and sinks are grouped on a control area basis.

The above assumptions may change in the future if the calculated ATCs do not accurately reflect our operating experience. More detailed modeling may be required for specific transmission requests.


Network and Firm Reservation Studies:

The most recent changes are shown  in Red.

The Duke Energy Carolinas Independent Entity (Midwest ISO) will process all Generator Interconnection requests and Network and Frim Reservation studies on Nov 1, 2006. All such requests on or after Nov 1, 2006 will be the responsibility of the Independent Entity.
