Joe is an expert on infrastructure for power grid operations including communication networks, SCADA, EMS, and data acquisition systems.  At Electric Power Group, he has been responsible for the WECC Phasor network project for real-time monitoring of the Western Grid and to install a monitoring system at CAISO.  He has:

Assisted the CAISO to acquire and install a Phasor Data Concentrator (PDC) and a display workstation.

Assisted the CAISO to request from the WECC Data Exchange Working Group (DEWG) permission to temporarily use the existing inter-utility WECC ICCP network to exchange phasor data between BPA, SCE, PG&E and the CAISO.
