The following 6 area system will be used to evaluate a MW transfer from Area A to Area F.
The following table describes the PTDF's, the ALC's and the inter/intra-area ATC's required to evaluate a MW transfer from Area A to Area F.
| Inter/Intra-Area Interface | Network Response PTDF (%) | Available Loading Capacity (ALC) on Limiting Facility (MW) | Inter/Intra-Area ATC (MW) | Area A to Area F System ATC (MW) |
