A Time For Transformation
28‐Mar‐19Transmission Roadmap 2
The energy utility landscape is going to transform more in the next ten years than it has in the previous one hundred. Somehow the utilities have to transform their operations, improve network efficiency and reduce cost… while never letting the lights go out.

Extensible FEP
Supported Operating Systems• Microsoft® Windows Server 2016• Linux 7
HTML5 Web‐based UI
Supports integrating with multiple host systems (e.g. primary site, backup site, QA)
Protocols this year• DNP3 (serial, TCP/IP, and secure)• IEC 870‐5 101 and 104• IEC 61850 client (telecontrol use case)
More will follow• ICCP• OPC‐UA
28‐Mar‐19Transmission Roadmap 7
Providing a common software based FEP that is used across the existing 4 platforms will eliminate the need to develop new protocols multiple times, thereby reducing cost (to GE and our customers) and accelerate the availability of new protocols to our customers.
