Energy Systems Integration Group

The Energy Systems Integration Group (ESIG), previously known as the Utility Wind Integration Group (UWIG), was established in 1989 to provide a forum for the critical analysis of wind for utility applications. Initially focused on wind power, UWIG expanded its focus to include solar power and distributed generation and become known as the Utility Variable-Generation Integration Group in 2011. In 2018, driven by the economics and growth of renewable energy and the interdependent nature of the global energy industry, the association expanded its focus beyond the electricity system of today. These expanding perspectives around energy, and the growing need for coordination across the ways that we produce, convert, deliver and use energy, are the reasons we have become the Energy Systems Integration Group (ESIG).
