2 Outline Perth H2omeSmart Program The Smart Meter Trial Implementation Participating households Engagement Strategies Data Analysis Participant feedback Future Lessons 2

3 Perth H2omeSmart Aim: 12% water use reduction in 10,000 households Methods: Target 18 high use suburbs Database 33,000 O/Os Apply CBSM techniques July 2011 Aug 2012 Invitation to participate, media Meter reading, feedback letters, eco-coaching Waterwise fixtures retrofit for pensioners Outcomes: Projected savings 10% by 10,949 households.

4 CBSM methods Typically, 4-6 rounds over 6-12 months

5 CBSM 0: Recruitment

6 CBSM 1: Reading your meter

7 CBSM 2: Data Analysis

8 CBSM 3: Feedback Letter Total savings by H 2 ome Smart households How use compares to others Raw data & water use calculations Agreed actions

9 CBSM 4: Eco-coaching

10 Prizes, newsletter, media promotions Before After

11 Start again: Read meter

12 Benefits of Smart Metering Utility Eliminate manual meter reads Ability to bill more frequently Integrate asset management, customer account & billing systems in one database. Customer Identification of leaks Improved customer service experience Water consumption more tangible 12

13 Smart or Advanced Metering Infrastructure (SMI or AMI) All of the hardware, software and connectivity required for a fully functional smart metering system. 13

14 The Water Meter 14

15 Smart Water Meters 15

16 Wireless Smart Water Meters No cabling from meter back to switchboard. Reduces installation costs (No trenches or fixed wiring). 16

17 Value in CBSM BCPs Actions can be directly linked to their consumption Flexibility in level of engagement Eco-coaching can be personalized and targeted In-house displays provide real-time data WATER SAVINGS! 17

18 The H20me Smart Trial 1. Test how real-time water use monitoring and online feedback could be integrated into the Perth BCP. 2. Test the use of real-time comparative/ normative feedback. 3. Greensense was the industry partner. 18

19 Implementation - Technology Greensense Platform is a multi-utility service. Greensense Process three parts; 1. Collection of data 2. Processing in real time 3. Present data on GreensenseView dashboard 19

20 Implementation - Data Collection Pulse head & data logger installed onto water meter at house. Logger notes a pulse every 1L or 5L used. Sends data through mobile 3G network 20

21 Implementation - Greensense View Launch Smart Meter Challenge dashboard Extract water consumption & # occupants data in number of formats. Compare water consumption between weeks through a weekly profile 5-minute interval profiles that showed specific end-uses to be identified (e.g. distinguishing toilet flush from shower from garden irrigation) 21

22 Implementation - Quintile module

23 Implementation - Heatmap Report

24 Implementation- Online Dashboard Water use in real time Daily weather/ quintiles Waterwise tips Competition between households 24

25 Participating Households Selection criteria, Selected participants offered meters. 9 households accepted the offer Pulse head and data logger also installed at Josh Byrne family home, ABC TV s Gardening Australia. 25

26 Results: Engagement Engagement with dashboard lower than expected; Letter & info packs sent as physical reminder of smart meter challenge (Round 4). Phone calls to prompt dashboard use (Rounds 4 and 5). Letter insert in response to participants forgetting log-in details/or not logged on to their dashboards (Round 5). 26

27 Results: Data Analysis Heat Maps - help identify anomalies & patterns of water use. Weekly Profile Comparison Reports - water use averages & maximums tabulated & graphed for 2 periods of time. Nature of this program means water reduction cannot be solely attributable to real-time data through online dashboard. 27

28 Results - Water Savings Most households made a water savings! Note: Season effect on consumption - large decrease in consumption coincides with winter & not direct result of smart meter installation. 28

29 Participant Feedback Initial feedback encouraging: We have been using the dashboard for just over a week now and have been checking the dashboard on a daily basis. Seeing how we compare to other households is very motivating. When we first logged in we were above the average now we are below and trying to get lower - I don't know how they can use so little water - if you have some insights please pass it on!. My partner has become very competitive about what we are calling the "Shower Peaks" on the graph; he is trying to use less water than me for each shower. When we first started I used considerably less water than him for showers now we are about even. So I think this Greensense meter has really helped him monitor his water usage because where I always think about my water usage he never did so it really has improved his water usage. 29

30 Lessons for the future Understanding meter limitations Visual display of real-time data & analysis for households must be used carefully. Effort required for successful engagement Carefully integrate the dashboard & data into ecocoaching Future programs can fully integrate smart metering with a CBSM BCP 30

31 THANK YOU ANY QUESTIONS? 31

Did you know a utility provider s sewer rates are typically 3-5 times higher than their water rates?

Did you know a utility provider s sewer rates are typically 3-5 times higher than their water rates? Why am I being billed? Utility costs are rapidly increasing. The owner of your community has chosen to have the residents pay for their utilities separately, which in the past were built into rent. Billing
