Objectives
1. What is “smart metering”?• Differentiation from AMR• Infrastructure requirements
2. What applications can be enabled by smart metering?• Demand response is just one of these applications• The business case should consider all the potential
benefits for all the stakeholders

The Energy Independence and Security Act of 2007
Today, President Bush signed the Energy Independence and Security Act of 2007, which will improve vehicle fuel economy and help reduce U.S. dependence on oil.
The bill the President signed today responds to the challenge of his bold "Twenty in Ten" initiative, which President Bush announced in January. It represents a major step forward in expanding the production of renewable fuels, reducing our dependence on oil, and confronting global climate change. It will increase our energy security, expand the production of renewable fuels, and make America stronger, safer, and cleaner for future generations

Dilemmas
• Dilemma Number 1– Many of the benefits of AMI require implementation
of the virtually the entire infrastructure (e.g. widespread demand response).
• Dilemma Number 2– Many different stakeholders may benefit from
advanced metering applications. It is complicated to build a model that effectively allocates the benefits between stakeholders.
• Dilemma Number 3– Solutions that meet the needs of short term
objectives may not be the best solution when applications that benefit all stakeholders are considered.

Why AMI?
• Operational Benefits– Automated meter reading– Remote
connect/disconnect– Theft of power detection– Interface to automation
systems (future)• Reliability Improvement
– OMS integration– Outage location– Improved restoration
procedures
• Energy Efficiency– Customer response to
information– Support for automation
systems to improve efficiency
• Societal Benefits– Response to emergency
conditions (load control, demand response)
– Information services– Advanced consumer
services– Improved security of
service

Distribution System Applications
• Fault Location• Outage Management• Optimize efficiency, voltage control,
var management, power quality• Demand control at the distribution
level (optimize investment)• Support system reconfiguration –
reliability improvement• Asset management support
(accurate loading information, operations information)
• Support Integration of distributed resources
What applications are possible when we have a database of load profile information from EVERY customer on the system and the ability to communicate with these meters for other information?

Conclusions
• Many AMI applications• Benefits to many different stakeholders• Requirements development process is based on the
applications• Different versions of AMI may be appropriate in different
situations– System characteristics– Customer characteristics– Load characteristics
