(Discontinued further AMR deployment 2007)
 140 residential electric meter AMI pilot deployed January 2008.
 Completed AMI Business Case December 2009.
 $19,500,000 SGIG from DOE & $1,240,000 EECBG from State
 Vendor selection completed… working on Best and Final Price
Thoughts on Where to Start
 Identify YOUR one or two Biggest Issues
 Power Supply Costs
 Reliability
 Workforce Retention
 System Losses

Startling Realization
 All kilo-watt-hours are:
NOT CREATED EQUAL - Cost Differences
Energy Rate ≈ $0.05 / kWh
Peak Hour ≈ $20.05 (400 x)
Gas: $3.50 / gal.
Peak Hour: $1,403.50 (400 x)
 The lowest cost kilo-watt-hour is:

Where Did We Start?
1. Developed a Vision
2. Identified 4 Broad Goals
3. Focused efforts on developing Strategies
Leesburg’s 2020 Vision
Leesburg will operate the best and most secure electric
grid available in the country by the year 2020 by
incorporating information and control technologies
that can support four goals:
 (1) empowering consumers,
 (2) rewarding conservation and energy efficiency,
 (3) improving distribution reliability and resiliency
 (4) expanding the use of renewable energy, distributed
generation, and alternative technologies.

AMI Evaluation &Vendor Selection
 Began with very comprehensive and detailed proposal
 Selected top four proposals for final consideration
 Weighted Score used to Rank final four vendors
 Final four presented a 3 day AMI demonstration
 Demonstration script and DA controllers
 Major emphasis on demonstrating ability to deliver
Distribution Functions
 Secondary emphasis on gaining a better understanding
of the technology and observing team interaction and
problem solving

Business Case & Cash Flow
 Desire project AMI elements to have good payback
 DA equipment treated as Capital Improvements
 Original AMI Business Case prepared in 2009
 First 2011 Project Cash Flow – Breakeven in year 19
 A dagger to the heart
 Revised 2011 project Cash Flow – Breakeven in year 6
 Working to be cash positive in year one!
 Customer Participation Required for Success!!!
Next Steps
 Finalize Communications/Marketing Plan
 Replicate successes of others
 Finalize Rate and Rebate offerings
 Share the savings
 Revise business processes for operational benefits
 One of the AMI elements
 Revise business policies for operational benefits
 Changing what we do as well as how we do it
Closing Thoughts to Consider
 Attack your biggest issues – our needs are different
 Focus on your Consumer - not the technology
 Create a Vision and Goals - to drive your strategies
 Prepare a Business Case – you may be surprised
 Smart Grid entry points – start with what you have
 AMI or Distribution Automation
 Learn from others – Good, Bad, and Ugly
 Replicate only the GOOD
 Your business model will change – back office impacts
 You must take action to compete!
