NEW: The GSF libraries are being migrated to .NET Core as the Gemstone Libraries


The Grid Solutions Framework (GSF) is an extensive open source collection of .NET code used by electric power utilities and various open source projects. GSF contains a large variety of code useful for any .NET project consisting of hundreds of class libraries that extend or expand the functionality included in the .NET Framework with a focus on tools and protocol parsers that are useful for the electric power industry.

  • Security framework for implementing role-based security in ASP.NET, WCF, WPF, Windows Forms and Windows Services
  • Windows Service Template for quickly developing windows services with remoting capability
  • Base WCF service for creating WCF services that can be self-hosted in Windows Service, Console, WPF or Windows Forms application

The Grid Solutions Framework, administered by the Grid Protection Alliance (GPA), is a combination of the existing Time Series Framework and TVA Code Library projects that were hosted on CodePlex. In creating the GSF, new code components have been added and the libraries have been refactored to make this integrated framework more secure and significantly better performing.

The open Phasor Data Concentrator (openPDC), Secure Information Exchange Gateway (SIEGate) and open Historian are examples of projects that use the Grid Solutions Framework.
