Stakeholder Technical Working Group Documents
The Stakeholder Technical Working Group (STWG) streamlines the previous working group structure by combining the previous working groups, Forecast Assumptions, Distribution Planning, Solution Evaluation and Optimization, and Grid Services Working Groups. Combining and streaming the working group structure will help to focus stakeholder time and efforts, provide opportunities for stakeholder presentations and allows for robust and comprehensive discussion and collaboration on various technical topics. The STWG will be utilized to address input and feedback on technical issues and increase transparency in the IGP process. For example, this technical working group could be used to solicit feedback on NWA opportunities, other acquisition of grid services, modeling sensitivity results, inputs and assumptions, among others.
