Microgrid Market Shifts

3. ► 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

4. ► 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. 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. 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. 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
