If you are a transmission planner, a renewables developer, or an independent system operator (ISO), choosing PSS/E isn’t just a technical decision—it’s a strategic one. It means fewer late-night debug sessions, fewer rejected interconnection studies, and a grid you can actually trust.

In transmission interconnection disputes—where a generator sues a utility for delaying grid access—the legal record heavily favors PSS/E. Courts have accepted PSS/E output as expert evidence in over 30 cases (e.g., NextEra v. Midcontinent ISO , 2021). No competing software has a comparable legal precedent.
