Energy Policy Makers Promoting Advanced Metering
Support for Smart Meters
Advanced Metering OIR
The policy of the U.S. is to
encourage time-based
pricing and other forms of
demand response and that
deployment of devices to
enable consumers to
participate in these
programs be facilitated,
and that unnecessary
barriers be eliminated
Goal
“Issue decisions on the
proposals for statewide
installation of AMI for all
small commercial and
residential customers by
early 2006”
(2005 Federal Energy
Policy Act)
(EAP II Draft, June 8, 2005)

Demand Response
“…begin implementing a
large-scale rollout of
advanced metering
systems for smaller
customers, targeted first
to areas of the state with
the highest peak
demand.”
(2004 Integrated Energy
Policy Report Update)

SCE AMI Business Case – Directional Cost/Benefit
Address fundamental cost drivers for last
business case
– Telecom network coverage, performance,
reliability and system management
– Meter failures and life-cycle performance
– Interoperability & system security
– End-to-end data management
Re-evaluate Aug 1st added functionality
– Interface to A/C load control thru PCT
– Remote service turn on/off

• Extend SCE’s data and
controls network to 5
million nodes (WAN)
• Leverage sensor
technologies for
customers and utility
distribution (LAN/HAN)
• Enable CPUC price response
requirements
• Interface with load control
technologies like CEC’s PCT
• Integrate programmable turn
on/turn-off switch
• Interface with home
information, automation &
control technology

Conceptual AMI System
SCE AMI system seeks to leverage a 2-way communications infrastructure
with 5 million intelligent devices on our distribution network for our
customers directly and our operations.

Utility Driven Meter Development Challenges
Achieve the right balance among Marketability, Functionality and
Openness
Develop a specification that is supported by multiple meter and
communications vendors and is commercially viable in the NA
utility market
Marketability
Leverage OpenAMI, Intelligrid,
Gridwise, CEC PCT, ANSI &
other standards and reference
design initiatives
Engage other utilities & vendors in
development process to generate
interest and feedback
Functionality
Openness
Durable open design that will support a solid
positive business case that provides customer value

available from at least three meter and
three communication vendors that meet
SCE’s minimum requirements for
performance and price by the end of

Product Selection
•
© Copyright 2006, Southern California Edison
Proactively engage in a close collaborative
process with selected vendors with the most
promising products in development
Rationalize the number of vendors that SCE
wants to engage on product development
In recognition of long procurement cycle (3-4
years), provide on-ramp for promising
products and off ramp for non-performing
products
Ensure level playing field for relevant vendor
information such as requirements,
architecture and future procurements
