1 Automatic Meter Reading Technology with benefits Peter Kjeldmann Development Adviser

2 Content Why AMR What is AMR? AMR technology Advantages of AMR Sarfannguaq and Qinngorput Perspectives of AMR

3 Reasons for AMR Relatively old meter park Difficult meter readings in some areas Time consuming manual labour Weak quality control of readings Minimal collection of data

AMR - 101 The ability to read meters automatically Readings arrive automatically at HQ More precise and

4 AMR The ability to read meters automatically Readings arrive automatically at HQ More precise and modern meters Elimination of predicted use billing Easier/better collection of consumption and production data

5 AMR - Technology Every meter contains a radio communication module Including logger module Data collection units placed in strategic areas Communication to central server via IP or GPRS

6 Logging module Event log Power outs Phase detection Cheating detection Monthly log One reading the last day of the month Daily log One reading each day at Hourly log One reading every hour or every 15 minutes

7 Meter readings Meter readings from all meters in a matter of hours Immediate reading of óne meter in a matter of seconds One reading of every electricity meter each day exported to billing system

8 Transmission of data Meter Server Server

9 Costumer advantages Predicted use billing eliminated More understandable bill Higher degree of correct readings Access to own meter through website Readings Statistics Better understanding of consumption

10 Company advantages Easier detection of fraud Collection of consumption and production data Reading of meters in hours in stead of weeks/months Grid analyses Loss analyses Replacement of old meters Savings in administration

11 Sarfannguaq Sarfannguaq 69 electricity meters Readings every 15 minutes 21 water meters Readings every month (battery life time) 2 concentrators Almost daily readings from June 2007 Started as a small development project

12 Data collection units Electricity meter Water meter

13 Electricity meter Water meter

23 Energy awareness Higher interest in energy Increasing energy prices Greater transparency in consumption First location of AMR

24 Inspiration for larger project AMR Sarfannguaq has resulted in using same system for rest of Greenland Over meters Done before 2014

25 Qinngorput 680 electricity meters Readings every hour 50 water meters Reading every month 2 concentrators

28 Perspectives Tool for: implementing renewables energy saving campaigns

29 Implementation of renewables Consumption must be known in detail Installation size Wind turbines Solar panels Hydro power How much storage is needed Electricity (VRB) Heat

30 Demand curve without industry

Implementation of renewables - Without industry 60 kw 99,99 % of consumption (115 MWh) 50 kw 99,8 % of consumption (114 MWh) 40 kw 98 % of consumption (112 MWh) 30 kw

31 Implementation of renewables - Without industry 60 kw 99,99 % of consumption (115 MWh) 50 kw 99,8 % of consumption (114 MWh) 40 kw 98 % of consumption (112 MWh) 30 kw 88 % of consumption (100 MWh) 20 kw 65 % of consumption ( 74 MWh) In 5 months from September to February Winter time with possible no hydro power Minimum of sun Wind?

32 Demand curve with industry

33 Implementation of renewables - With industry 120 kw 99,99 % of consumption (234 MWh) 100 kw 99,9 % of consumption (233 MWh) 80 kw 97 % of consumption (228 MWh) 60 kw 88 % of consumption (205 MWh) 40 kw 64 % of consumption (150 MWh) In 5 months from September to February Winter time with possible no hydro power Minimum of sun Wind?

34 Energy savings Forthcoming energy saving campaign Savings can be seen directly on Energy saving tips also on AMR will be linked directly to the energy savings
