Siemens planned an orderly migration. Version 34 supported both SafeNet and CodeMeter concurrently. However, starting with version 35.0, CodeMeter is mandatory. Users still on SafeNet must contact Siemens support to transition their licenses before they can install or run v35 or v36. Additionally, the CodeMeter Runtime shipped with PSSE 36.0.1 was updated to version 8.00 to address potential licensing issues.
The — 35.2 as of early 2025—represents a generational leap in power system simulation. From true 64-bit processing to grid-forming inverter models, Siemens PTI has addressed the most pressing needs of modern grid planners. However, the upgrade requires careful license management and model validation.
As the global energy sector faces an influx of renewable energy, data center loads, and decentralized grids, the latest version of PSS®E addresses these modern challenges. It introduces . Core Evolutionary Upgrades in the Latest Version 1. Version-Independent Dynamic User Models (VINDP)
Siemens manages its power system software using a strict development and maintenance schedule. System planning coordinators, utilities, and external consultants must closely monitor these lifecycles to maintain standard compliance. PSS E Version 36 - Siemens psse latest version
Recognizing the need for scalable, collaborative, and high-performance computing, Siemens introduced . This cloud-native iteration of the platform offers a transformative set of capabilities:
: AEMO's transition period began in August 2025, with full industry-wide adoption expected by Drivers for Change
As the energy landscape shifts toward renewables and decentralized power, the latest release of PSS®E introduces critical enhancements designed to handle the complexity of the modern grid. What is the Latest Version of PSS®E? Siemens planned an orderly migration
: PSS®E 36 supports dynamic user model DLLs that are version-independent. This means you can reuse models across future releases without constant recompilation.
PSS®E continues to be the "industry standard" for a wide range of analytical functions: PSS®E Version 36 - Siemens
PSSE’s Python API (formerly psspy ) has been optimized for Python 3.11. Key improvements include: Users still on SafeNet must contact Siemens support
The PSS®E 36 series remains the actively recommended, feature-complete release version for consultants and utilities running short-term and active grid studies. With the rollout of v37, the v36 series will enter a maintenance phase, locking out new features but providing limited security fixes and bug patches for six months.
Siemens has established a clear support roadmap for the year: PSS®E Version 36 - Siemens
