12 Seattle s AMI Strategy Deploy pilots in new development areas (2006) Complete a Business Case (2006). Evaluate the pilots (2007) Work with Utility management and City governance to evaluate AMI for funding Formulate a go forward AMI plan

13 About Our Pilots High Point Pilot (700 residential meters) Outsourced except for end points Validate monthly versus bi-monthly billing impact 1-way RF, both water and electric South Lake Union (1,000 meters) Own everything 2-way RF technology Mix of customers (commercial, high-rise residential) Geographical challenges (Seattle hills, urban canyons) Electric distribution system: both downtown network and radial

Production Network: South Lake Union / Denny Triangle 1 UtiliNet Take Out Point (TOP) 16 UtiliNet concentrator/repeaters 2-way electric: form 12S meters (455) 2-way electric: polyphase meters (32) 1-way water: residential and commercial (30) 3. Test Network: North Service Center 1 TOP 1 UtiliNet concentrator/repeater Test meters: 2-way electric (9) and 1-way water(3)

23 Why SPU/Water is dropping out The Pilot tests both water and electric Water requirements vary greatly from the electric: 1-way is adequate Electric utility has a business case that supports going on our own with 2-way technology RF Network for 2-way only is less expensive to deploy and operate

24 Business Case Results Say Go! Capital Investment = $59 million Deployment interval = 5 years AMI system (model) life = 15 years Annual Benefits, 100% installed = $ 9 million Discount Rate Net Present Value Benefit / Cost Ratio Internal Rate of Return 3% $ 32.7 M %

25 The Benefits Are Many ($ millions) 22% 11% 13% Net Present Value of Benefits 1% 1% 24% 28% Meter Reading Account Services Meter Accuracy Revenue Recovery Cash Flow Call Center Distribution Ops NPV of Benefits NPV of Capital NPV of Operating Cost NPV of AMI Project NPV $ $ $32.7

26 A Word about the Financial Model Financial planning is important Discussions regarding numbers bring out the real issues which are about people, jobs and change The pilot doesn t confirm all the financial assumptions We became comfortable with installation cost We became confident about capital cost We understand we will have to manage labor transitions We re not yet confident about the cost to interface into legacy systems

27 Recommended AMI Strategy Complete meter and billing systems Meter data management in 2007 (in progress) Replace complex billing system for time based rates in 2008 Rollout AMI to 100% of meters, area-wide Start soon (2008 or 2009) Complete rollout in 5 years or less Improve other processes using AMI data Outage Management (OMS) and GIS Asset Management, Load Flow, Distribution System Planning Customer Billing/Relationships (CIS/CRM)

33 Windstorm December 14-23, % of customers out 95% restored in 3 days We could have used restoration management information during this big storm if we d had it. System Operations Center Dispatcher, Jan. 2, 2006

34 Opportunities and Challenges Resource Requirements rapid installation will mean outsourcing installations Workforce Transition Plans 55% of the benefits result from personnel reductions These FTE reductions are in excess of normal attrition Major Business Process Changes

35 Focus on Accountability Use the business plan as a benchmark for accountability achieve the benefits The better our labor transition plan (the faster we reduce labor cost) the better the ROI for the project The expansion will require that we re-bid the technology to the vendor community

36 Seattle City Light - Vision The best customer service experience of any utility in the nation. Billing and Payment Options Rapid Power Restoration Information Help customers manage their energy use Business process efficiencies support lower rates

37 Seattle City Light The Green Utility The best customer service experience of any utility in the nation.
