Vision and Strategy Statement for the Utility of the Future Team
Vision Statement for the Utility of the Future Project Our vision is to transform the operation of our electric power grid
by creating a networked infrastructure capable of delivering and receiving information from intelligent devices distributed across our power system, automating components of the distribution system and leveraging the network for improved operational efficiencies and improved customer satisfaction.
Strategy Statement for the Utility of the Future Project Our strategy is to investigate, select and deploy intelligent devices
across our distribution system which will measure, protect and automate the grid, combined with a communication system linking the intelligent devices in a networked fashion, creating opportunities for system wide load response, enhanced outage management, better asset management, more efficient operations, and empowering customers to use electricity more efficiently.

Distribution Lines 4,160, 12,500, 24,000 Volts
Metering and Sensing Devices Metering and sensing devices will deliver information along a digital communication infrastructure.
Data Collection and TransmissionNodes along the distribution lines will collect data about the system and communicate to the operations center in real time across a digital communication infrastructure
Digital Communication Infrastructure
The communication system will provide a mechanism for transmitting data, controlling and automating multiple devices along the distribution path, including applications behind the meter
Innovations at the TransformerThe transformer will support various endpoint measurement an control,
including potential metering advances.
Creating a Digital Grid
• Digital components are easier to scale as the system grows
• Programmability of digital devices is easier
– Ability to build intelligence into end devices
• Advances in digital technology can be adopted from other industries
• Richness and volume of data available using a digital system is superior to analog
• Digital controls enables near real-time operational decision making
• Automated meter reading at more frequent intervals
• Workforce and work order management is enhanced
• Remote connect and disconnect capability
• More accurate meter reading and billing
• Outage management improvements
• Power quality monitoring
• Asset management
Operations Benefits
The Benefits of the Digital Grid - Operations
• Digital applications are widely supported across industries
• Data communication is easier and faster using digital technology
• Graphical user interface for the utility and utility customers becomes a reality
• A variety of technology solutions, such as wireless, BPL, Wi-max, etc., are available using digital communications
Communications Benefits• Broadens the scope of customers
eligible for demand response programs
• Asset optimization through real time information flow
• Better load forecasting and load study data at more frequent intervals
• Enables real time rate structures
• Load control capability
• Firmware upgrades reducing the potential hardware obsolescence
The Benefits of the Digital Grid – Communication
Revolutionary vs. Evolutionary Changes
One way information flow
Invites tampering
Incremental changes to the meter dictated by existing back office
processes
Metering Today
Electromechanical in a digital age
Networked Communication
Business process dictates meter technology
Bi-directional Information flow from the meter
Meter can be the gateway to home automation
Interface with the utility becomes dynamic creating real time information capabilities
Enables additional utility services
No power data nor control
The meter is another sensor in a wide array of interactive sensors on the network
Connecting the Network
• Higher bandwidth
• Increasing number of communications nodes
• Distributed generation control
• Multiple backhaul paths
• Device interoperability
• Open communications protocols
• Utility price signals to smart appliances
• Meter as a premise “portal”
• Remote connect/disconnect
• Upgradeable firmware

Trends in Network Communication
Integration of Operations and Communications
Selection Criteria and Guiding Principles
• Networking infrastructure project, not just AMI or AMR
• Standards-based hardware and software products
• Operational and business decisions should not be constrained by infrastructure choices
• Guiding principles include:
– Ability to choose products and services from best in class companies
– Communication network can carry information from any device
– Standard connections with minimal integration efforts
– Ability to remotely upgrade and adapt devices
Key Concepts Leading to theUtility of the Future
Utility Head End System
Proprietary network does not “exclude” other utility assets
WAN selection is not dependent on meter technology
Communication to the home can go through or around the meter
Open, IP based standards “invites” innovation from outside the utility industry Multiple
devices can use the WAN

Extending Into the Home
Power lines are the ideal connection into the home– More reliable and economical than RF – ANSI 709 open standard – 1,000+ LonMark Certified products – Secure authenticated and encrypted data exchange
PLC in Meter reaches every home outlet and switch PLC is not blocked by or interfered with existing 2.4GHz home networks PLC is not subject to RF multi-path fading in fixed point communication PLC can be used to bridge to home gateway and RF devices inside the home The NES network provides a low-cost, universal, bi-directional communications
18
Fundamental Design PrinciplesLeverage the power of networks
Data networks share expensive resources to reduce cost per connected point– Networked printers, networked servers, shared broadband
connection, …
Advanced metering networks should too– Spread cost of “expensive” components (e.g., modems, backhaul
connection) across many meters and devices
The NES system is not a “PLC” system
The NES system is not an “RF” system
The NES system is an IP networked system– Leverages the strengths of each to lower deployment cost, lower
operating costs, and lower life-cycle costs
19
Fundamental Design PrinciplesUse best-of-breed standards
Each element of the system uses standards optimized & proven for that application domainMeters built on proven metering standards
ANSI C12.18, ANSI C12.19Networks built on proven networking standards
ANSI 709, TCP/IP IT interfaces built on proven enterprise standards
XML/SOAP (Web services)
Leads to highest quality & security Drives down cost of network connectivity, IT
integration– The largest contributors to total cost of ownership for an
advanced metering system
20
Fundamental Design Principles“Never visit the meter again”
High level of “base” functionality built into every meter Enable/configure functionality remotely instead of
replacing products– Built-in, firmware controlled disconnect in every meter– Hourly metering and multi tariff in every meter– Prepay support in every meter– Power quality in every meter– Multi-channel data logger/load profiling in every meter– …
Remote upgrade rather than replacing products– All components support remote firmware upgrade
Long-lived, reliable products– Designed for >20 year life with <0.3% annual failure rate
21
NES MetersMarket-leading advanced functionality
Detailed electrical measurements– Active and reactive energy– Import and export metering– Flexible time of use metering
Extended information & alarms– Multi-channel data recorder– Power quality data and alarms– Tamper and theft detection– Connectivity to other meters and devices
200A disconnect under glass– On/off– Load limiting/service upgrade to any level– Prepay
“Virtual IP” card in every meter– Share a single physical IP connection– Communicate to in-home devices
Remote firmware download support Designed for >20 year life with <0.3% annual
failure rate Traditional, compact form-factor
22
NES network operating system – Enables choice of off-the-shelf
applications– Supports quick development of
custom applications and integrations
Scalable to millions of devices
Redundant architecture Backward-compatible Standards-based SOA
