Siemens Elevates Industry Trusted Transmission Planning Software, PSS®E, to the Cloud

Dallas, TX  |  May 23, 2022

  • Launches the first cloud-integrated grid simulator software for transmission planning
  • Leverages the same trusted software and user interface, with more than 2,000 APIs and use of existing scripts
  • Provides scalable computation power, a secure collaboration environment, flexible remote working, and more
  • Now available in U.S. and Canada with future global rollout planned

Siemens has launched its time-tested transmission grid simulation software, PSS®E, to the cloud. Today, transmission grid planners and their IT departments are facing increasing pressure with growing simulation requirements due to the rising number of renewables, changing energy consumption and generation patterns, and new workforce expectations. With PSS®E Cloud, users will be able to better address today’s grid planning challenges in a familiar software, while providing the flexibility to accommodate future needs of the energy transition.


Cloud capabilities provide transmission utilities with better visibility into operations and planning of the power grid. Planners can run a countless number of scalable what-if scenarios in only a fraction of the time it used to take. In addition, planners can tackle extensive simulations with more complicated and varied scenarios that were previously not practical due to time constraints, such as some of the large-scale renewable integration studies required for today and in the future.


In addition to accelerated simulations, PSS®E Cloud also helps alleviate process inefficiencies. Planners can spend less time crunching data (e.g., preparing data for the simulations, waiting for results, etc.) and more time interpreting it. For example, typical planning studies that are accelerated by almost seven times can save engineers up to 85% of wait time. And since it is available in the cloud, they can securely store, share, and sync model data from any location – even when working remotely.


“PSS®E Cloud is a value-driven and low-maintenance offering that saves users time, money, and headaches,” says Rafael Da Silva Ozaki, business unit head of Grid Software at Siemens Smart Infrastructure USA. “It balances the need for speed with the accuracy required for compliance studies and security measures, while also helping utilities navigate the complexity and unpredictability of the grid.”


Moving grid simulation to the cloud also has many IT benefits. Individual users no longer need to worry about the complex IT installation and approval processes that are associated with maintaining local licenses and downloading the newest version to access the latest enhancements. IT personnel do not need to anticipate regularly upgrading and replacing servers and other IT infrastructure to keep pace with increased use-demand, peak computation power, or updated system requirements.


Utilities may be able to realize reduced CAPEX expenditures by leveraging a cloud infrastructure. In addition, cloud deployment significantly minimizes the return to operation window after an event occurs compared to an on-premises system.


The Siemens Cloud Operations' secure-by-design infrastructure is proven by deployments around the world. The infrastructure adheres to most cybersecurity best practice standards, including certifications by Fedramp, NIST, and ISO27001 compliance, and demonstrates additional compliance with CCM and CSTAR registry.


PSS®E Cloud uses AWS cloud platform to host utilities’ data. For customers that prefer a different hosting mechanism, PSS®E can also be self-hosted within customers’ own data centers or on other cloud platforms.
