# California ISO Adds Siemens’ Real-Time Contingency Analysis Software to Manage Full Network Model

California Independent System Operator Corporation (ISO) has extended its partnership with Siemens to include Real-Time Contingency Analysis software as well as Siemens’ Energy Market Management system.

The software, a component of Siemens Spectrum Power™ transmission network applications, supports the growing ISO Full Network Model, which provides a detailed and accurate representation of the power system, ensuring California ISO has a more accurate assessment of real-time system conditions.

The Real-Time Contingency Analysis software simulates mores than 2,000 separate equipment failures in the ISO’s footprint and neighboring areas every two minutes, alerting the system operator of potential issues.  Ultimately, California ISO will be able to identify potential transmission system problems earlier, allowing grid operators more time to take preventative actions, ensuring reliability.
