Energy Exchange: Federal Sustainability for the Next Decade

Technology Improvements Enable Efficiency

• DOE provides R&D, Test facilities, and limited demonstration and development support

IT, RE, and power electronic improvements are shifting how electricity is generated, distributed, and consumed

• Old: Customer load dictates Utility generation• New: Customer owned generation, utility/customer

communication enables collaboration, efficiency, and resiliency

Energy Exchange: Federal Sustainability for the Next Decade

Utility Example

Hawaiian Electric Company (HECO) and SolarCity• SolarCity sponsored inverter load rejection

overvoltage (LRO) tests in ESIF, results allow HECO to double allowable rooftop PV on distribution system

• Benefits to military housing and installation

Energy Exchange: Federal Sustainability for the Next Decade

Government Microgrid Example

Marine Corps Air Station (MCAS) Miramar microgrid project to increase energy security, provide islanding capability, and reduce energy use & costs • Raytheon leading project to integrate Zn/Br flow battery and Intelligent

Power and Energy Management (IPEM) technologies • IPEM controller tested in both grid-connected and islanded modes with

generation, energy storage, and load simulators in NREL’s Energy Systems Integration Facility in 12/14

• Demonstration at MCAS Miramar is anticipated to be in 2015
