Single-Source Contingency

Download a report on single-source contingencies, limits placed on external and generation interfaces in which losing a single piece of equipment could cause a loss of 1,200 or greater megawatts (MW).

The single-source contingency limit is the base limit plus the authorized margin multiplied by the margin sensitivity. The NY Central-East single-source contingency limit is based on the authorized margin divided by the Distribution Factor (0.30). The margin associated with NY Station Voltages has been converted to MW.
