2026 Event Schedule

Meter vendors have offered many new innovations with AMI 2.0 devices.  New meters are capable of analyzing waveform data and providing power quality, enabling utilities to get much more value out their meter fleet.  Most AMI 2.0 devices are capable of running applications at the edge.  Unfortunately, these application environments are not interoperable.

To address this, in 2024 Southern California Edison partnered with the Linux Foundation to define an interoperability specification for the grid edge:  GEISA, the Grid Edge Interoperability & Security Alliance.  SCE has been working with supporting utilities, including Duquense Light, National Grid,  Portland General Electric and San Diego Gas & Electric  to define the requirements, and with platform vendors including Aetheros, Honeywell, Itron, Kalkitech, Landis + Gyr, Sense, and Utilidata to device the technical specification.

GEISA specifically address the execution environment for edge applications, a common API allowing them to access meter data and functions, and a common approach to management.  When complete, GEISA will allow utilities to deploy apps from different vendors to devices from different vendors, using a common management platform.  Importantly, GEISA will allow this interoperability to occur in a secure manner, using consistent vetted approaches to cybersecurity

In this talk, Michael & Richard will explain what the GEISA specification covers, how it meets utility needs, and how it can advance interoperability at the grid edge.  Michael & Richard anticipate being able to demonstrate initial GEISA implementations.
