1 Customer Preferences & Solar PV Adoption Jen Robinson Steven Coley Nadav Enbar Behavior, Energy, & Climate Change Conference October 17, 2017

2 The power system is changing Combined Heat and Power Demand Response Home Energy Management Rooftop Solar Electric Vehicles Distributed Solar PV Distributed Energy Resources (DER) Generation Becomes More Flexible Consumers Become Energy Producers T & D Becomes More Controllable and Resilient Power Flow Loads Become More Interactive and Dynamic A More Dynamic End-to-End Power System 2

3 What technology and services do customers want? What will they adopt now? In the future? Generation Planning Time distinct load and availability RPS Management Stock Load Research & Pricing Net premise load shapes Generation Operations Time distinct local load changes Adoption Drivers Preference/ Adoption Models Market Share Estimates Distribution Planning Distribution Operations Localized stock, performance Customer Solutions Marketing Localized net circuit loads Informing program design Targeting programs to customers 3
