Since the start of the Utility Variable-Generation
Integration Group (UVIG) in 1989, it has adapted as the industry has evolved
from an initial focus on the analysis of wind for utility applications to
impacts of increased solar and other distributed generation to now other energy
sources, such as battery systems. This
advisory reviews the evolution of this organization, and how UVIG is now
changing its name to the Energy Systems Integration Group (ESIG) to keep up with industry changes.
