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

Rollout follows SmartMeter program deployment
