Vanguard standards for DC and hybrid AC/DC microgrids.
EMerge Alliance leads the adoption of safe, resilient, economical and sustainable distributed energy power systems for buildings and communities — through open standards and market development, with members across industry, government and academia.
Why direct current
The three pillarsResiliency
Adapt to changing conditions, and withstand or recover rapidly from disruptions — power that stays on when the grid does not.
Savings
Manage energy sourcing, storage, conversion and use to achieve the greatest total-cost-of-ownership savings.
Sustainability
Cost-effective, efficient system integration of sustainable energy resources, from rooftop solar to community microgrids.
Flagship standard · IDM v1.2
A common data language for every microgrid device.
The Interoperability Data Model (IDM) Standard defines an open JSON schema for the critical power-flow characteristics of microgrid devices — sources, conversion, storage, distribution, protection and loads. Open-source licensed, on GitHub for public review, and feeding the RE+Source PRO product catalog.
- OEMs register device data models in an open public library
- Non-proprietary data, readable by AI-enabled and traditional design tools
- Committee meets the second Friday of each month — members shape every revision
