What is Smart Metering?

Systems that measure, collect and analyze energy usage and interact with smart meter through various

communication media either on request or predefined schedules. The infrastructure include hardware,

software, communications medium and electricity meters

Level of Application For

Home Energy Management (HEM) / Demand Side Management (DSM)

Slide |17

Level of Applications for HEM / DSM

Level Item DSM Features Description Ranking of

Implementation

1 Utility Meter Provide Info through In Home

Display (IHD) Unit

Customers decide and do manual individual

load switching

Minimal cost to utility to implement, IHD can be owned

by customer 2

2

Utility Meter Provide Info to feed into

Customer HEM/DSM System

Auto DSM load switching by Customer

owned HEM

Minimal cost to utility, compatibility of meter with

Customer HEM is the key. Intel is currently developing HEM on

a similar platform

Implementation

Utility Meter Provide the Communication

Gateway for DSM Application

Customers Do the switching for DSM

remotely or automatically through

energy Meter as Gateway

Bandwidth is the key to implementation, can be costly

4

Utility Control the Customers Load for Demand Control/

Loadshed purposes

Special Agreement with Customers needed (e.g.

incentives for customers)

Can be costly to utility to control individual customer loads, operational limitation

and business case not clear to utility.

If utility want to control/load shed the whole supply to a

particular customer, it is possible through the Remote

Disconnect Feature (but not for individual customer load).
