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

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

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

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).
