Microgrids Attract Private Investment in Security and Grid Services
• Police/Fire• Medical Center• Assisted Living• Schools• Communications• Shelters• Hotels• Fuel Stations• Water, Waste
Water, Flood Protection
• Residential Towers
Grid Services
• ISO ancillary Services
• Price response
• Utility grid support (voltage, VAR’s)
Customer Services
• Renewable generation
• Higher levels of power energy efficiency
• Providers of islanding capability if grid is lost
• Power Key Facilities and services when the grid is lost
• Provide services to protect the grid• Lower statewide peak demand & prices• Improve power efficiency and emissions
