50 years of PSSE

Powering the future of grid planning

For half a century, PSS®E has delivered the precision, stability, and trust essential for mission‑critical transmission planning and analysis.

Discover PSS®E

50 years proven reliability in power system simulation

For 50 years, PSS®E has set the standard for power system simulation - delivering the precision and stability mission‑critical transmission planning demands. Built alongside the engineers who rely on it, PSS®E has shaped every major era of grid modeling, evolving from early transmission studies to today’s data‑driven, automation‑powered workflows.

With standardized models, benchmark‑quality performance, and unmatched analytical depth, PSS®E is trusted by a global community of grid planners. As grids grow more complex and the industry moves toward autonomous, intelligent networks, PSS®E bridges past and future - trusted for decades and built to power what comes next in grid planning.

Celebrating the founders of PSS®E

Long before PSS®E became the industry standard, it began as something simpler — and far more powerful: a tool created by engineers who needed answers. Not a product roadmap. Not a business strategy. Just brilliant minds tackling urgent power system challenges with rigor, ingenuity, and a deep commitment to the grid. Today, we honour the original pioneers whose vision shaped PSS®E and the modern era of grid simulation: Lionel Barthold, Dag Reppen, Paul De Mello, Robert Ringlee, Dale Hedman, Allen J. Wood and Wayne B'Rells.

PSS®E isn’t just software — it’s the engine that has built, and continues to build, the world’s power systems. For decades, every power systems engineer has relied on it to plan, operate, and shape the grids that power global prosperity.
