Activities of interest
PSERC
• Reviewing project progress in separate meetings (using
distance conferencing or net facilities/services) that will
take place in-between the IAB meetings (42)
• Making sure the final reports for completed PSerc
projects are properly reviewed and advertised (37)
• Producing a list of research areas of interest for the
solicitation of new proposals (37)
• Conducting the review process and ranking of the
proposals (32)
• Initiating review of the Statement of Work (SOW)
documents for the projects in similar research areas
making sure the coordination of the research activities is
optimized (18)

New Efforts
PSERC
• Engaging experts from industry members
• Establishing field data repository for
evaluation of new concepts
• Creating field demonstration site for PSerc
“show-case”
• Providing financial means for moving from
concepts to practice
• Branding and marketing PSerc T&D
