DC Lighting and Building Microgrids: Opportunities and Recommendations



Cover of white paper

Supported by the U.S. Department of Energy, Pacific Northwest National Laboratory (PNNL) conducted research to characterize the current state of DC lighting and building microgrid market and technologies. This research included extensive literature reviews, interviews of 28 subject matter experts and manufacturers, and a formal Request for Information (RFI) to DC lighting and microgrid controller manufacturers. The RFI was released April 23, 2020, and garnered 46 responses over 9 weeks. PNNL’s research identified a growing market of available technologies along with significant potential benefits including energy savings, resiliency, reliability, and reduced costs. This white paper explores the findings of this research and offers recommendations for stakeholders concerning moving forward with these beneficial technologies.
