Our utility paradigm is changing… will YOU be ready? Paul Kalv Smart Grid Research Consortium Electric Director October 20, 2011 Chief Smart Grid Systems Architect City of Leesburg, Florida

Leesburg Overview 23,000 electric customers also provide gas, water & internet. 9,700 (42%) AMR electric – 18,900 (34%) AMR total meters. (Discontinued further AMR deployment 2007) 140 residential electric meter AMI pilot deployed January Completed AMI Business Case December $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 ???

Top Priority... Reduce Peak Demand 2007

What was Bad… is getting Worse!

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

Charges Based on Coincident Peak

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.

Focus - Empowering Consumers AMI Related Technologies Advanced Metering Infrastructure ( Focus: Consumer Needs not Technology ) Smart Meters. Communications network, or 2 or 3 or 4…. or more Meter Data Management System Communications infrastructure and meter installation Enterprise Service Bus Field Acceptance Testing Home Area Network In Home Display and web portal Programmable Communicating Thermostat Direct Load Control Pay-as-you-go

Focus: Rewarding Efficiency & Conservation Energy Efficiency & Conservation Initiatives Consumer Education & Information to change behavior Communications Plan Who to notify When to notify How to notify Create Focus Groups to receive consumer input Time Differentiated Rate Schedules – offer choices TOU, PTR, Direct Load Control, Other Utility control or Consumer control Security and Personally Identifiable Information(PII)

Focus – Improving Reliability and Resiliency Reliability and Resiliency Initiatives (Automation) Cyber Security Substation Power Transformer w/Smart Grid monitoring Distribution Transformer Monitoring Integrated Distributed Generation Communicating Distribution Automation equipment SCADA Upgrades Communicating Faulted Circuit Indicators Trip Saver Cutouts Integrated Volt/VAR Control

Focus – Expanding the use of Renewable Energy, Distributed Generation, and Alternative Technologies “Preparing for the Future” Initiatives - ( Complete) Integrating customer owned Solar PV systems Integrated Distributed Generation – Utility and Customer “Preparing for the Future” Initiatives - ( Future) Integrating PHEV Load and Storage 2 MW Battery Storage at each of our 5 substations ???

Current and Emerging Technologies Ready Now: Demand Response DG & Renewable Resources Distribution Automation Metering – (Reliability and remote upgrade issues) Meter Data Management Systems Outage Management Systems Field Installation Services Business Process Change Management Pay-as-you-go

Current and Emerging Technologies Good Improvement and Choices – will become better: AMI Communications – (DA monitoring and control?) DAN Communications Customer Web Portal In Home Display ZigBee vs. WiFi Storage – huge potential for reliability and DR benefits

Current and Emerging Technologies Future – Not yet ready for prime time: Home Area Networks Standards are slow to emerge Smart Appliances

Leesburg’s DR Strategy To Date Strategies Conversation Voltage Reduction (CVR) Integrated Distributed Generation - City Gensets (IDG) Partnering with hospital and two Supermarkets (LRCR) Results Saved $1 st MM in 14 months Saved $2 nd MM in 7 months and 3 rd MM in 7 months CVR IDG LRCR FY MW $591 K 35.2 MW $654 K11 MW $222 K FY MW $492 K 42.8 MW $861 K15 MW $304 K

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

Final Evaluation Spreadsheet

8 Field Demonstration Sites

DA Controllers at each Site

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!
