Renewables & Distributed Generation (RE/DG)

The RE/DG work group delivers tools and products that provide guidance in renewables, energy storage, and distributed generation adoption and deployment by building and maintaining an advanced business and technical knowledge base through partnerships and focused research. The unique role of this work group, together with other internal and external stakeholders, helps co-ops understand the opportunities and challenges, and engages the co-op communities around the issues of renewables, energy storage, and distributed generation. Ultimately, these resources and tools assist electric co-ops in being industry leaders in renewables through well-informed decisions and responsible investments in renewable technologies that affect their future growth.
