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.

How does it work?

The HAN can use ZigBee Wireless Communication protocol with a centralcontroller 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 inUtility’s Demand Response programs 

Via the HAN, consumers are able to cycle back appliances during peak hours andalso 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 adjustedto 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 usepricing

HANs facilitate an

awareness of energy

cost and consumption

and make energy

conservation easy, fun,and engaging

Significant savings for each stakeholder include:

Utility GovernmentConsumer

• Reduce annual energy

usage and cost by 10 -15 %

• 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 withcustomers 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-centeredchallenges

Consumer DataPrivacy

• Usage data

available to

public

• Consumers can

operate in

standalone mode

or communicate

with utility
