Business Case for AMI

1. Business Case for AMI Andrew Chastain-Howley

2. part 1•Utility drivers• AMI Solution

3. Water Utility drivers for AMI Water resource management • Water resource conservation • Nonrevenue water usage reduction Customer engagement • Access to timely and reliable usage information to consumers • Improved meter reading • Education through information Infrastructure management • Extending the life of existing infrastructure assets • Enhanced targeted maintenance activities • Improved prioritization of investments

4. Water resource management Impact of irrigation inefficiencies Impact of customer leaks 5-10% waste 90 gallons a day or more via leaks Fixing leaks in 5% of American homes can save 177 billion gallons of water annually Consumers generally more concerned about the waste of water than the bill impact of leaks Source of all statistics on page: U.S. Environmental Protection Agency, WaterSense, Statistics and Facts, http://www.epa.gov/WaterSense/resources/facts.html

5. AMI Driving Changes Insert Graph Source: Pike Research Report on Smart Water Meters Published 3Q 2010 AMI based water meters that deliver hourly consumption data via a fixed-network communications system • 2009: 8% of the 39 million water meters read remotely in the US and Canada • 2016: estimated to grow to 26%. Growth driver: Water conservation 36 U.S. states will face water shortages by 2013, according to government projections AMI provides a water agency with a wealth of new information and new engagement capability

6. Evolution of Metering for WaterMetering technology capability has evolved over time AMR • Single ping based reads • Single consumption values • Walk-up/Drive by reads • Meter to Collection Device one-way communication • Focus on meter reading & data collection AMI • Time interval based reads • Multiple consumption values • Fixed network reads • Metering end points to utility two-waycommunication • Focus on water management & monitoring

7. Battery powered devices Battery Life: A major difference between electric smart meters and gas or water meters Water striving for 20 year battery life Strategies to conserve power • Highly efficient power management • Low power radios • Battery devices may not act as full nodes in mesh smart meter networks Challenges • Fewer facilities available for placement than other utilities • Transmission/Distribution infrastructure underground • Data need to be transmitted from indoor or pit water meters to the collectors Lithium batteryLong-life

8. Meter Data Management systemsWhat is an MDMS? MDMS is a software system that provides • Meter read/consumption data exception management • Automated data analytics • Data driven support for improved operational focus Supports customer engagement strategies

9. Capabilities —Water Focus Scale of meter data with an AMI at hourly interval read capture • 720 reads a month (for one meter) • 7.2 million reads a month (for 10,000 meters) • State of California (10 million meters) 7.2 billion reads per month… MDMS provides a database repository and utility-specific business logic • Automate and streamline the complex process of storing AMI water meter data • Evaluate the quality of that water data and generate estimates of read exceptions and gaps • Deliver that data in the appropriate format to utility water billing system & to end users The critical role of an MDMS is to pre-process granular interval meter data at large volumes very quickly

16. SESSION 4•AMI/MDMS Case Studies

17. Coachella Valley Water District (CVWD) Time Of Use Study City of Palm Desert, served by Coachella Valley Water District Funded by the California Energy Commission PIER (Public Interest Energy Research) Program Purpose • Determine if water customers will shift water use out of peak period (Southern California Edison peak period weekdays, noon-6pm, June-September) • Determine if on peak water savings will result in on peak electrical savings by water agency

18. Leak Detection During study, approximately 30% of residences experienced leaks (defined as continuous water flow for 24 hours) 28% of residential leaks required component repair or replacement Residential leaks totaled 165,000 gallons per month, 7% of total participants water usage.

19. Customer Water Usage Reductions Customers that participated reduced water consumption as compared with control group Large on-peak reduction and smaller total reduction

20. CVWD tou study REsults Residential customers reduced peak use and also reduced overall consumption Reduced CVWDs peak period electricity demand by about 6.5kW No statistically significant shift in Commercial, industrial and irrigation water peak or total usage; however these groups benefited from the leak detection • 30% of business participants had leaks, wasting about 6% of their total water use • About 15% of irrigation class experienced leaks, wasting about 3% of total water use

21. Sydney Water, Australia Service area is in New South Wales, Australia where the government was encouraging electric smart meter systems. Provides water and wastewater service to 1.8M properties. Study was designed to look at synergies between water, electric and gas AMI. Initial study looked at benefit opportunities. The study initiated further trials of smart metering including a 1,000 household collaborative study with Energy Australia.
