SDG&E’s Vision of the Future

• Fundamental premises

• Build a system supporting both SDG&E and State’s

requirements for reliable electric energy

• Inform our customers on consequences of consuming

energy at peak usage periods

• Work with customers to manage their electric load

• Anticipate technology changes and adopt to them when it

makes sense

• Operate our business efficiently and reliably

SDG&E’s Vision of the Future cont.

• Three primary technologies

• Meter technology both monitors electric consumption and

communicates with consumer; gas modules tie in to


• Two-way communication infrastructure between SDG&E

and all individual electric meters and gas modules

• Software that collects meter data and integrates with other

utility applications

• “Smart Grid”

• As technologies advance we envision Smart Metering as

an enabler for our smart grid roadmap

• Distributed generation (DG), self-healing network, etc.

Vision: Meter/Modules/Enabling Technology

• Meter and meter communication system

• Gateway between the utility and the consumer.

• Remote disconnect.

• View meter communication system as access to the

consumer’s programmable communicating thermostat (PCT)

and other enabling technology.

• PCT functions

• Utility controls load by communicating with PCT

• Grid reliability demand-response (DR) program

• For economics or calls a price responsive DR program

• Two-way communication customer confirms DR event, but

A/C was not on

• Notification PCT no longer receiving/responding to

communication network

Vision: Meters cont.

• Meter must support remote firmware


• Ability to add new features such as power quality, new

markets, distribution system asset optimization, pre-pay

• New customer services, medical alerts, home security,


• Meter also network sensor

• Meter should be capable of not only recognize net

metering, but also participate in distributed generation

Vision: Communications

• Designed for two-way information flow

• New services could be added

• Require high-speed communications

• Home area network (HAN)

• Open industry standards, non-proprietary, inter-operability

• Working with the other CA IOU’s as directed by the CPUC

• Secure means of sending information between SDG&E

and end points (tolerant of attacks)

• Communications infrastructure supports our

long-term vision to collect:

• Power quality information

• New sensor data for smart grid, building automation designs

• Grid state (monitoring, automation)

Vision: Optional Communications Requirements

• Smart Meters also support future technology upgrades and

process improvements to enhance the capabilities of Electric

Operations, Gas Operations, back-office field and mapping

support, and Customer Care, etc.

• Implementing smart enterprise-wide technology and process

improvements that make our operations more efficient

• This would support plans for micro-grid communication and

control, autonomous, self-healing systems

• Other potential benefits: intelligent alarming, electronic maps,

remote SCADA-based controls, restoration switching

analysis, planned switching, etc.

Vision: Software (Application)

• Ability to leverage outage management

systems to detect outages

• Ultimately enable transmission and

distribution (T&D) operations to sense and

review information from many data sources

• Either aggregation or as finely detailed as necessary

• Communicate with consumer whereby

system designed to add new functionality

as customers require

• Provide DR and energy efficiency information to

consumer via PCT, in-home display, other enabling


• May offer consumer centralized energy management

system or allow use of information to manage own


Smart Meters are Foundational









Vision for the

future is to optimize

use of technology to

improve service to

customers and











Smart Meters

Vision: Customer, Customer, Customer

• SDG&E is committed to exceptional customer experience

• Smart Meter success hinges on customers embracing the

data it provides

• Need to make it simple/easy

• Focus on Smart Meter customer benefits

• Enhanced customer service

• Improved outage management

• Greater control over energy usage/bills

• Reduced need to access property

• Looking at services/products can we develop that provide an

exceptional customer experience with Smart Meters

• Potential offerings: proactive notification, personal rate options


• Customer initiatives

• Interaction channels, office of the future, virtual enterprise


• Innovative rate programs

• Peak Time Rebate

• Enabling technology

• Education

Next Steps

• CPUC approved April 12, 2007

• Achieves Demand Response

• California Energy Commission goals

• Full deployment

• Technology and Installation RFP May 10th

• Select technology Q4 2007

• Meter rollout 2008 – 2011

• Continue monitoring market place
