A Modular Approach to HAN Connectivity Barry Haaser Lakeview Group
Agenda How important is consumer choice in the value proposition? Which standards are likely to find consumer acceptance? What role will gateways and energy system interfaces play in the home? How do modular interfaces fit into the picture?
Home Area Network Status Over 30 million smart meters are installed in the US Most meters contain HAN interface Only 2% of meters are HAN activated Energy System Interface (ESI) Smart meter or broadband device? Good dialogue regarding HAN interoperability Is interoperability achievable?
HAN Outlook
Consumer Energy Attitudes 80% of broadband households invested in energy savings 40 50% of consumers find residential energy management solutions appealing 62% of consumers take steps to save money 10% of respondents are attracted to energy management services if offered by their electricity supplier Consumers expect 15 20% discount on their electricity bill Consumers interested in electricity plans with free devices saving 15% off monthly bills Source: Parks Associates
Utility Options for Energy Savings Source: Ecoalign
Enabling the HAN SEP Smart Meter Utility vs. service provider AMI vs. broadband Wired vs. wireless SEP 2.0 vs. OpenADR2.0 Self vs. professional installation Secure vs. unsecured devices In-home display vs. ESI OpenADR IP OpenADR Residential Gateway SEP Smart Meter
Communication Options
Demand Response Empowering the consumer: New rate plans and programs Customer incentives Customer installable Works everywhere Eliminate stranded assets Enable standards development process Still viable in 30 years 9
Customer Choice In-Home Displays Energy Gateways Communication Modules Load Control Thermostats Appliances
Home Area Network Connectivity Smart Meters Utility HAN Devices HVAC & Hot Water White Appliances Consumer Electronics/PCs Home Automation Energy Displays Pools & Spas Electric Vehicles Renewable energy Irrigation Etc.
HEM Networks Home Area Network (HAN) Utility term for home energy network Energy System Interface (ESI) is the meter HAN devices communicate with smart meter Focused on demand response or pricing program
Which HAN Standards Will Succeed?
HEM Networks Independent Residential Energy Management (irem) Offered by service provider Ranges from simple Programmable Communication Thermostats (PCTs) to complex energy management systems Can be part of a larger system for home automation, security, entertainment, lighting, etc.

Conclusion Dominant HAN standard will take years to achieve It s not all about utilities Demand response and dynamic pricing programs will drive consumer market USNAP clarifies demarcation point of Utility Program/Consumer HAN, reduces risk of stranded assets We need to enable customer choice, innovation & open competition unknown unknowns the ones we don't know we don't know
