Microgrid Market Shifts
► Aging transmission/distribution► Regulatory and financial obstacles to upgrade systems► Increased vulnerability/impact of severe weather► New man-made threats to the grid► High penetration of PV in some markets shifts peaks► Customers demanding grid services
Power Delivery Challenges
► Reduced reliance on backup generators► Any generation source could be integrated► New features focused on grid-tied operation► Optimization of efficiency and cost/revenue in both grid-tied
and islanded modes of operation
Microgrid Evolution
5
Drivers for Military Microgrids► Warfighting takes place remotely► Cyber threat to electrical grid is significant threat► Traditional backup power systems intended for 8-24 hours;
new threats could impact installations for 6-9 months► Policy-driven increase in renewable generation; stranded
assets when utility fails► Lack of O&M funding, system training degrading on-base
systems
6
Moving Beyond Pilots and Demonstrations► SPIDERS Phases 1, 2 and 3 (ECIP)► FDA White Oak Campus CHP-based microgrid (ESPC)► MCAGCC Twenty-nine Palms (ESTCP, expansion via MILCON)► Tooele Army Depot renewables/energy storage (ECIP)► Schofield Barracks utility peaking plant (EUL)

Current Challenges► Understanding ownership of assets and rights of access• Utility, customer, third-party PPA
► Understanding impacts to utility rate schedule• Demand charges based on power export?
► Minimizing operational impacts during implementation► Increased complexity of distribution operations• Changes in safety protocols• Preparedness for infrequent events
