PSS®E Xpress

PSS®E Xpress - The Essential Power Flow Toolbox!

In recent years, major blackouts around the world have increased awareness regarding the benefits of accurate modeling for improved system planning. Municipalities and cooperatives that have traditionally relied on regional independent system operators (ISO) or transmission owners (RTO) to provide planning modeling, need to be more actively involved to ensure the accuracy of their own system representation. To streamline the process of exchanging data with their ISO, RTO, or other governing body, utility companies, municipalities and cooperatives need a solution to perform essential tasks in a cost-effective manner.

To address these challenges Siemens PTI offers PSS®E Xpress. Derived from our market-leading PSS®E transmission planning software and a 40-year heritage, PSS®E Xpress includes essential functions for modeling and data exchange.
