2. Energy Policy Makers Promoting Advanced Metering
Support for Smart Meters
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
(2005 Federal Energy Policy Act)
Advanced Metering OIR
Goal
“Issue decisions on the proposals for statewide installation of AMI for all small commercial and residential customers by early 2006”
(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)

5. AMI Meter Design Objectives
Expand meter metrics and analytics beyond the revenue cycle to distribution power characteristics and operational information
Extend SCE’s data and controls network to 5 million nodes (WAN)
Leverage sensor technologies for customers and utility distribution (LAN/HAN)
Metrology &
Intelligence
Telecom
Open Design
& Standards
Demand
Management
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
Create a durable design to match 15–20 year lifecycle based on interoperability and open standards

6. 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.
Illustrative Example

7. 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
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
Durable open design that will support a solid positive business case that provides customer value

Customer Interface
Delivery
Energy Procurement
Field Services/System Recovery
Installation & Maintenance
Multiple clients read demand and energy data automatically from customer premises
Customer reduces demand in response to pricing event
Distribution operator curtails customer load for grid management
Real-time operations curtails (or limits) load for economic dispatch (ES&M)
AMI system recovers after power outage, communications or equipment failure
Utility installs, provision and configure the AMI system
Utility remotely limits or connects/disconnects customers
Customer reads recent energy usage and cost at site
Distribution operations optimize network based on data collected by the AMI system
Utility procures energy and settles wholesale transactions using data from the AMI system --
Utility maintains the AMI system over its entire life-cycle
Utiltiy detects tampering or theft at customer site
Customer uses pre-payment services
Customer provides distributed generation
Utiltiy upgrades AMI system to address future requirements
Meter reading for gas and water utilities
Multiple clients use the AMI system to read data from devices at customer site
Distribution operator locates outage using AMI data and restores service - -

10. Technology Assessment/Procurement Plan
Goal:
Competitive commercial products available from at least three meter and three communication vendors that meet SCE’s minimum requirements for performance and price by the end of Phase I
Objectives:
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
Identify Potential Vendors Worldwide
