2 INTERCONNECTED SOLAR SOURCED MICROGRIDS: THE ENERNET WHY? WHAT? HOW? EARLY ADOPTERS

3 WE RE AT A TIME OF INCREASING CHALLENGES TO OUR POWER SYSTEMS: FROM POINTS OF GENERATION - TO POINTS OF USE - AND EVERYTHING IN BETWEEN

4 Solar sourced Microgrids can capture the key virtues of the Internet using a similar topology Self Organizing Virtues Presumption of Access Equality of Each Entity Bottom-Up Public Structure Strength of Weak Transactive Cooperation Self Healing = Resilient Solar sourced Microgrids will create a massively distributed mesh network of system sources, storage and loads Estimated # of Interconnected Nodes 1970 Today Internet 50,000 7,500,000,000 Smart Grid 37, ,000 Enernet 37,000 1,700,500,000

5 A Residential Microgrid Operates Independently or in Cooperation with Other Grids Residences: Personal Power System Operate on or off grid(s) Under the owner s total control Conducts power transactions by choice Basic infrastructure node in the Enernet

6 A Residential Solar Sourced Microgrid Operates Independently or in Cooperation with Other Grids Includes: Site Based Solar Energy Production Electricity Storage Co-located Loads Appliances, Devices Intergrid Connection

7 Home Microgrids can be Ener-connected into Community Microgrids

8 Commercial Building Level Microgrids are Similar Commercial: Corporate Power System Operate on or off grid(s) Under the owner s total control Conducts power transactions by choice Basic infrastructure node in the Enernet

9 Commercial Building Level Microgrids are Similar Includes: Site Based Solar and Wind Energy Harvesting/Production Electricity Storage Co-located Loads Appliances, Devices Intergrid Connection Power Storage & Control Office & Occupied Space Factory or Warehouse Data Center

10 Commercial Building Microgrids can be Ener-connected into Commercial Campus Microgrids

11 Community & Commercial Microgrids can be Ener-connected with Utility-Scale Microgrids Peaking Power Plant Sub-station Community Microgrids Solar Farm Commercial Campus Microgrid Wind Farm Sub-station
