12 Audience Poll #2 How big was the U.S. solar market in 2013? 12

13 Trends Driving The Smart Inverter Market 13

14 Professional Investing Era Has Started “SunEdison up 9% on ‘yieldco’ IPO news” “NRG Yield IPO ‘could transform access to capital’” “SolarCity Securitization Deal Jolts Solar Energy Industry” “SolarCity Announces Pricing of Second Securitization”

15 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.

16 Most Capital Unavailable to RE Investment Source: The CityUK

17 Public Capital Vehicles Could Lower LCOE 8-16% Source: Financing U.S. Renewable Energy Projects Through Public Capital Vehicles: Qualitative and Quantitative Benefits (2013); Mendelsohn, M. Feldman, D.

18 Early Commercialization Finance Gap Transitional Assistance Needed

19 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:

20 Concerns About Grid Imbalances Are Growing

21 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

22 Smart Inverters & Storage Coming Together Demand Response StorageGeneration Voltage Support Regulation Fast Ramping Frequency Response Peak Load Reduction Dispatchable Quick Start Dispatchable Solar/Wind Wider Operating Range (lower Pmin) Over Generation Mitigation Load Shift

23 EPRI/SunSpec California Solar Initiative Smart 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

24 Opportunities for Integrators 24

25 Early Smart Inverter Projects  Cooperate with utilities  Build revenue models  Showcase expertise

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

27 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

28 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
