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

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
