PGEs SmartMeter Program
  • Automated meter reading for all customers
  • 10 million meter upgrades
  • A communications network
  • IT systems
  • Frequent meter reads - daily for gas, hourly or
    15 minute interval for electric
  • Enhanced customer benefits over time
  • Automated meter reading
  • Secure online access to detailed energy usage
    data
  • Better billing reduction in call volumes
  • Outage management
  • Remote connect / disconnect, load-limiting
  • Home area networking

SmartMeter Timeline
10.1 million meters installed
Key Functionality Milestones 2007 Replatform IT
systems for high data volumes Anchor bill on
automated reads 2008 Bill on interval reads (for
select customers) Secure customer online access
to interval usage data Successful rollout of
SmartRate (res. CPP) 2009 (targeted) Outage
management Electric remote connect / disconnect
December 2008 1.7 million meters installed
Millionth meter installed 9/5/08

SmartMeter Deployment Challenges
  • Meter Issues
  • Meter access
  • Obstructed meters
  • Multiple meter designs
  • Handling for special meter types (e.g. TOU
    meters)
  • Evolving Electric Technologies
  • Maintaining deployment momentum
  • Vendor Issues
  • Ramping supply chain to deliver required volumes
  • Deployment vendor resource flexibility
  • Network Siting
  • Availability of overhead structures for RF
    network equipment
  • Optimizing Realization of Program Benefits

SmartMeter IT Challenges
  • Scale Complexity
  • Establishing IT platform to handle huge volumes
    of data
  • Scaling meter data management
  • Integration complexity many system interfaces
  • Standards
  • Immature industry standards
  • Driving an open, standards-based solution with
    multiple vendors
  • Vendors
  • Vendors early-stage products limited experience
    and resources
  • Distributed Computing
  • How to best leveraged distributed processing
    capacity
  • Ensuring robust security

Successful deployment of SmartRate pricing plan
  • Recruitment
  • 10,000 voluntary participants in summer 2008
  • Experience
  • Across 9 called events, achieved average
    residential customer reduction of 16.6, and an
    average non-CARE residential customer reduction
    of an impressive 22.6
  • 7 of 10 customers saw a reduction in their
    cumulative summer bills
  • Retention
  • 90 of customers intend to stay on the plan in
    2009

11
Online Customer Access to Usage Information
  • Displays energy usage by billing cycle, month, or
    week
  • Displays hourly electric usage by day
  • Ability to overlay temperature
  • SmartRate customers view usage framed by peak
    periods
  • Customer service reps able to view same graphs
    online

Home Energy Management
Advanced
Enhanced
Basic
  • Fully automated intelligent energy management
    system
  • Other automated/ programmable appliances
  • Electric vehicle charging / storage
  • Distributed generation and storage
  • More comprehensive in-home displays (usage, cost,
    time)
  • Programmable Communicating Thermostat (PCT)
  • Simple high-low indicator
