OpenIBR is a universal, open-source grid-forming controller for inverter-based resources (IBRs) and large electronic loads, built on three principles: simplicity, grid-forming controls, and transparency. Verifiable and aligned with IEEE 2800 and UNIFI, it's designed to behave predictably in both simulation and the field.

Heron Power is the initial developer and steward of OpenIBR today, with the intent of growing it into an open, community-governed standard. We welcome contributions and feedback from grid modelers, developers, utilities, and researchers across the industry.
