The 2026 ESIG Spring Technical Workshop will be held at the Loews Ventana Canyon Resort in Tucson, Arizona.

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). This new positioning fulfills ESIG’s commitment to create a vibrant, compelling, and sustainable professional association that provides our members with the timely sharing and distribution of information, research, analysis, operations knowledge and peer-to-peer networking required by the changing global energy industry and the future industry landscape. ESIG does this by providing:

• Collaborative thought leadership at the forefront of energy systems integration and operations.

• Technically-grounded information and education without lobbying, selling or advocating.

• Timely review and distribution of research on emerging technologies and practices.

• Solutions that maximize asset utilization and optimize profits.
