  11. Audience Poll #2How big was the U.S. solar market in 2013?

  12. Trends Driving The Smart Inverter Market

  13. Professional Investing Era Has Started “SolarCitySecuritization Deal Jolts Solar Energy Industry” “NRG Yield IPO ‘could transform access to capital’” “SolarCityAnnounces Pricing of Second Securitization” “SunEdisonup 9% on ‘yieldco’ IPO news”

  14. U.S. RE Industry Needs A Lot Of Capital Source: Financing U.S. Renewable Energy Projects Through Public Capital Vehicles: Qualitative and Quantitative Benefits (2013); Mendelsohn, M. Feldman, D. http://www.nrel.gov/docs/fy13osti/58315.pdf

  15. Most Capital Unavailable to RE Investment Source: The CityUK Source: The CityUK

  17. Early Commercialization Finance Gap Transitional Assistance Needed

  18. Solar Access To Public Capital Initiative • Goals • Cover early commercialization gap • Investigate way to expand capital base • Lower costs of RE financing • Results • Identified public market mechanisms • Securitization • Master Limited Partnerships • Delivered standard documents & processes • Engaged 250 investors & developers • Initiated “mock” securitization Download: http://www.nrel.gov/docs/fy12osti/55021.pdf

  19. Concerns About Grid Imbalances Are Growing

  20. California Rule 21 Changes Coming • Rule 21 defines how solar plants connect to the grid • New revision permits smart inverters • To “support” the grid • Enable new services & revenue streams • Set stage for U.S. rollout

  21. Smart Inverters & Storage Coming Together Generation Storage Wider Operating Range(lower Pmin) Voltage Support Regulation DispatchableSolar/Wind Fast Ramping FrequencyResponse Over GenerationMitigation Dispatchable Quick Start Load Shift Peak Load Reduction Demand Response

  22. EPRI/SunSpec California Solar InitiativeSmart Inverter Test & Certification Program • Supported by leaders • SMA, Fronius • SCE, SMUD • Sandia, UL • Demo full integration • Technical controls • Market signals • Utility networks • Enables broad deployment • Sets stage for U.S. roll out • Harmonizes safety standards

  23. Opportunities for Integrators

  24. Early Smart Inverter Projects • Cooperate with utilities • Build revenue models • Showcase expertise

  25. Last Mile Network Integration Private Cloud Grid Operations Utility/ISO Inverter Tracker Plant Controller Meter String Public Cloud Module Plant Controller IPP O&M Storage Enviro End-To-End Security, Monitoring & Control Solar Plant Applications

  26. PV + Storage Solutions • California mandate to add 1,325 MW storage by 2020 • Cal ISO enabling “Flexible Ramping” product sales • “Second Life” EV batteries driving economics

  27. Summary • Smart inverter era has started • Opportunities emerging • New deployment scenarios • New revenue & product/service opportunities • Broader utility cooperation • Act now to lead this exciting field
