This newsletter recaps key accomplishments in 2023, the second year of the UNIFI consortium operation. Reading on, you will learn all about our recent push towards long-term organizational sustainability, our contributions to modeling and simulation, our effort in driving consensus on specifications, the unique 1 MW multi-vendor demonstration at the Energy Systems Integration Facility (ESIF) in the National Renewable Energy Laboratory (NREL), and how we continue to push education and outreach for this technology. A bonus article looks back into history on other multi-vendor experiments.
