: Unlike Version 34, which relied on the deprecated Python 2.7, Version 36 uses current Python 3.x standards for its 2,000+ open APIs , improving both security and productivity.
: Version 36.3.1 adds support for the Intel® oneAPI Toolkit 2025.1.0 Fortran Compiler (IFX), keeping the tool aligned with modern development standards. psse latest version

: The software now includes automatic model format upgrades , reducing the manual effort required when migrating legacy project data (such as older .raw or .dyr files) to the latest version [11, 22]. Pros and Cons
To find the latest version of PSSE (Power System Simulation for Engineering), which is a tool used for power system analysis and simulation developed by Siemens, I recommend checking the official Siemens website or their support and download pages.

Pre-configured data files for simulating large solar and wind farms.
As of my latest knowledge (early 2026), the newest version of (Power System Simulator for Engineering) is version 35 . It is developed and maintained by Siemens PTI (now part of Siemens Digital Industries Software).
Siemens PTI has moved away from annual major releases to a continuous delivery model. Users with active maintenance contracts (SWPC) automatically receive updates. Always check the official Siemens support portal for the exact build number (e.g., 35.2 Build 02).
To satisfy stringent regulatory standards like NERC TPL-007-02, the GIC module has been updated with optimized Alpha and Beta benchmark event scaling profiles [1.11]. Through automated python hooks via the gicdata module, users can instantly scan worst-case geomagnetic storm orientations and variations, computing the exact DC injection profiles impacting power transformers, switched shunts, and load shunts [1.11].

Siemens has focused the latest releases of PSS®E on addressing industry pain points such as model migration, user experience, and the computational demand of large-scale, complex simulations.
PSS®E 36.3.1 and later offer full support for the Intel® oneAPI Toolkit Fortran Compiler, ensuring blazing-fast execution times for large-scale network simulations.
The latest version includes native "aggregate DER" models. As distributed energy resources (rooftop solar, batteries, EVs) bid into wholesale markets, you need to model their aggregate impact on transmission. Old versions can't handle the node count.
Here is everything you need to know about the latest state of PSS®E.
: Version 36.3.1 recently added support for the Intel® oneAPI Toolkit 2025.1.0 Fortran Compiler (IFX).
