Analyze & Visualize Thousands of Contingencies in Minutes

ETAP Contingency Analysis (CA) allows users to define component outage and failure scenarios. From the user-defined scenarios, system N-1 and N-2 contingencies are studied. ETAP contingency analysis employs a fast screening or ranking algorithm to select a ranked contingency list for detailed studies.
