The GEISA project is working on several products that would enable grid edge interoperability that consists of:

  • GEISA Specification (Draft Target 6/30/2025) for:

    • ADM: Application & Device Management

    • API: Application Programming Interface

    • EE: Execution Environment

  • Sample Implementation (Target Q3 2025) for a GEISA API and Execution Environment

  • Conformance Tests (Target Q1 2026) for each of the above specification

The specification should be sufficiently defined that a conformance test can be performed for each component of the specification. The above products define the minimal set of requirements to provide basic interoperability and a consistent environment for edge application developers.

Beyond GEISA 1.0

Future iterations of GEISA would expand the definition to increase interoperability and capability across the edge environment

  • GEISA 1.x

  • GEISA 2.0

    • Native Implementation as opposed to containerization

    • Move towards Build Once vs. Write Once

    • More API’s for other types of hardware support
