Grid Modernization: Metrics Analysis (GMLC1.1) - Sustainability; Reference Document, Volume 5

This report summarizes the accomplishments of a three-year project funded by the U.S. Department of Energy (DOE) titled "Grid Modernization Laboratory Consortium (GMLC) 1.1: Metrics Analysis." It first describes the importance of metrics for grid modernization and then introduces the six categories of metrics DOE has developed to guide the Grid Modernization Initiative. It then describes the approach the Grid Metrics team took to working directly with industry stakeholders to develop new grid metrics and demonstrate their use. This report is accompanied by six separate reports that provide more detail about the work of the Grid Metrics sub-teams on each of the six metrics categories and to assess the current uses of metrics in these categories to inform grid modernization decisions.
