What is a HAN? A Home Area Network (HAN) is a residential local area network (LAN) for communication between digital devices typically deployed in the home, usually a small number of computers and printers and mobile computing devices. “ ” Source: Wikipedia

How does it work? The HAN can use ZigBee Wireless Communication protocol with a central controller that communicates with appliances. The central controller collects appliance information wirelessly and presents the state of the household on a dashboard.

Why implement a HAN? Show consumers their wasteful habits… …and empower them with real-time data to save energy Currently With HAN Consumer can get their energy usage instantaneously and act on their wasteful habits Previously Consumer serious interest in energy savings Consumer had to wait one month for their energy bill

HANs create an opportunity for customers to engage in Utility’s Demand Response programs Via the HAN, consumers are able to cycle back appliances during peak hours and also turn off non-essential devices during peak hours. Consumers are now able to shift appliance energy usage patterns over time. As a result, home energy consumption is monitored and adjusted to achieve the desired level of energy and financial savings. Customers Can: “Set it and forget it” Realize energy savings and compare against peers in their community Establish a savings goal and view progress towards achieving that goal

The benefits of HAN technology are expansive Consumers are provided data and metrics on: Hourly / weekly usage Peer to peer comparison HANs provide real- time information on: Detailed energy usage information by device Energy savings Temperature / Weather Curtailment messages from Utilities Time of use pricing HANs facilitate an awareness of energy cost and consumption and make energy conservation easy, fun, and engaging Awareness Real Time Info Analytics

Typical communication environment with Utility

Significant Energy Savings for each Stakeholder GovernmentUtilityConsumer Stakeholders

Significant savings for each stakeholder include: UtilityGovernmentConsumer Reduce annual energy usage and cost by % Remotely control appliances / devices View energy usage and percentage of total consumption for each appliance / device Automatically reduce energy usage of appliances during peak hours Instantaneously view energy usage instead of waiting for next month’s bill Reduce peak demand Improve customer service by providing load control Faster outage detection Include residential and commercial customers in DR programs Communicate with customers instantaneously Eliminate manual, on-site meter readings Reduce the need to build new power plants Reduce carbon footprint Reduce air pollution Decreased dependence on foreign energy Preserve the environment

Implementation of HANs could result in some data-centered challenges Consumer Data Privacy Usage data available to public Consumers can operate in standalone mode or communicate with utility Data Tsunami Massive amounts of usage data Opportunities for software vendors to provide creative programs to customers Consumer Interest Savings main driver Green planet Challenges are an opportunity for companies

Time-of-Use Pricing will influence consumer behavior Utilities will communicate with customers in real time Customers will respond to utilities in real-time Dynamic Time-of-Use Pricing results in adjusted consumer behavior
