PAAC (PowerGEM AFC / ATC Calculator)

PAAC is software for calculating NERC MOD 30-compliant Available Flowgate Capability (AFC) and path Available Transfer Capability (ATC) values. It is a key part of the electricity transaction management system that coordinates existing schedules and future reservations within the bounds of the grid capability and established business rules. Calculated values are ready for OASIS posting for all standard time horizons and products. The PAAC Viewer is a user-friendly Excel-based interface that is used to study and document PAAC calculations in a more interactive manner.
