Price Overview

DIgSILENT PowerFactory pricing policy depends on the needs of a particular customer. The required functionality, completeness of licenses and, accordingly, the price depend on several factors:

  • Type of license: single-user, multi-user or server versions.
  • Functions required. There are standard sets of PowerFactory software package: Basic, Distribution networks, Transmission networks, Industrial enterprises, Business (design organizations). In addition, it is possible to create a personal package of functions or supplement the standard set with the advanced ones.
  • The number of nodes at the user's choice: 100, 250, 500 and an infinite number of nodes.
  • Number of licenses purchased: each next license costs significantly less.
Thus, an individual pricing policy allows the consumer to choose the most suitable option in each case, taking into account the individual needs and form a package of modules that meets the exact customer’s requirements.
