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)

7

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
