Introduction: The System Operator Transmission Owner Code (STC) has been amended recently to include, for future requirements, the transfer of elements of Phasor Monitoring Unit (PMU) data directly to the National Grid System Operator. SSEN presently views PMU data on the Secondary Operational Network (2nd OTN) by directly contacting the PMU. SSEN has no facility to actively gather the PMU data, nor is it possible to make elements of PMU information available to a third party.

Objectives: Produce a report that outlines the different system architectures options available for managing PMU information.
