SDG&E Smart Meter Program

Challenges:• Rate Challenges:

• Communicating CPP for > 200 kW

• 1 year bill protection between CPP and TOU

• On-line rate comparison available

• Averaged 1 hour for Account Executives to explain rate to customers

• CPP for > 20 kW C/I customers (20,000 customers w/o Account Executives)

• Rate design will be simpler (lower CPP rate)

• 12 month data available before CPP rate offered

• 1 year bill protection between CPP and TOU

Wave 1 – Meter Installation Support Application Development and Integration (March, 2007 – July, 2008)

Wave 2 – Billing & Remaining AMI Functionality Application Development and Integration (January, 2008 {estimate} – January, 2009)

Interface taken off the scope as the result of Phase 0 analysis.

Pending interface, needs verification from business process workshop and final business case decisions.
