5 ENERGEX & Metering Dynamics ENERGEX is a Distribution Utility in South East Queensland covering mi with 3800 staff servicing 2.8M customers Metering Dynamics is a commercial business unit of ENERGEX Metering Dynamics provides Metering and Data Collection to : 1. ENERGEX, 2. Australian National Electricity Market participants 3. Direct to Private Customers

8 METERING THE AUSTRALIAN CONTEXT Australia operates a Contestable Electricity Market All Consumers in the Eastern States can choose their retailer. Competition has be foremost in the design of the market place to provide the best choice and value to consumers. ELECTRICITY Distribution and Transmission is regulated as these are natural monopolies.

9 AUSTRALIAN CONTESTABLE MARKET Market Participants consist of: Unregulated Customers Retailers Sells power and collects revenue from customers Distributors Poles & wires Generators Regulated MP ( Meter Provider) supplies, installs and maintains meters and comms Market Regulator ( NEMMCO now AEMO) MDP ( Meter Data Provider) read data, process and validate data and push to market.

10 MARKET BACKGROUND The Contestable Market in Australia is relatively mature (10 years +) Most Meter Data Providers (18) in Australia use MV90 to collect meter Data. Metering Data (15min) is collected, validate, processed and delivered to the market daily by 8 am for previous day. Communications - GSM/3G used for ~95% of all Aust remote metering ENERGEX has been using MV90 since 1986 ENERGEX s MV90 System is relatively large with dialling capability of 90 concurrent CSD and 20 IP sessions. Metering Dynamics is the 2 nd largest by volume Meter Provider & Meter Data Provider in Australia and the Largest by Area Serviced. Metering Dynamics Takes Pride In being #1 in Data Quality Delivery performance in the Aust Market

11 Electricity Market Responsibilities Australian Contestable Electricity Market Place has well defined roles, responsibilities and rules for market participants. Part of those responsibilities relates to the quality of data from the electricity meter and its operation Market Rules state The Metering Data Provider must maintain and operate a system to undertake remote acquisition and data collection services. Systems and processes must be in place that enable; (a) The commissioning of each metering installation into the Metering Data Provider s metering database; (b) The remote communication with the metering installations at each site; (c) The remote collection of interval metering data from the metering Installation inclusive of any assigned significant metering data alarms; and, (d) The storage of metering data from the metering installation in the Metering Data Provider s metering database.

12 Electricity Market Responsibilities Australian Contestable Electricity Market Place has well defined roles, responsibilities and rules for market participants. Part of those responsibilities relates to the quality of data from the electricity meter and its operation Market Rules state (c) The remote collection of interval metering data from the metering Installation inclusive of any assigned significant metering data alarms.

13 Commercial Impacts of NEM rules MDP is commercially responsible for delivery / action of significant meter events and alarms. Failure to meet this responsibility for more than 6 months exposes the business to full cost recovery of lost market revenue caused by any meter problem. This can run into millions of $$$ dollars on some sites. AS A RESULT In the Australian context meter alarm and events are as important as the interval data itself.

14 METER DATA COLLECTION MV90 collects a variety of information while undertaking interrogations. TOU data, Interval data and events are some of the things collected. The TIM is the primary mechanism that controls what is collected. Meters in the Field

15 ALARMS What Are Critical ALARMS Example (Ram/Rom, VT Fail, Clock Fail, Calibration, Analogue Reference, A/D Converter) Metering Dynamics has categorised alarms into two categories. Billing Those alarms that have a direct Metrological Measurement impact. Asset Management Those alarms that don t have a direct impact on billing data, but require some action to remediate (e.g. Battery Fail)

16 METER STATUS, EVENTS AND INTERVAL STATUS Various Meters have various methods to indicate a metrological or health issue. Today s Modern meters usually support at least two of these methods. Events Generally the meters event log which contains a history of important events in the meters life this varies from user logon to phase failure, clock fail etc. Meter Status Typically real time status at the time communications occurs. These are now mapped using New TIMS into MV90 s Event logs as statuses. Channel Interval Status Many modern meters now provide extensive channel and interval statuses Validation report, one of the outputs of these alarms.

17 ALARMS AND SPECIFIC METER TYPES Each Meter Type and TIM has different capabilities and functionality in reporting alarms. The ability to successfully detect alarms and events depends on The Meters Functionality and Capability The TIM s Implemented Functionality The configuration of the MV90 system Business Rules and Processes. Itron Have added NEW Functionality into MV90XI SP1+ of advanced TIM Specific Events Validation. TIM Documentation is the best Place to Start

18 Example of Modern Meters with sophisticated event and alarming capabilities. TIMS AND DOCUMENTATION

19 TIMS AND DOCUMENTATION Example of Modern Meters with sophisticated event and alarming capabilities. Interval Status Mapping

20 TIMS AND DOCUMENTATION Example of Modern Meters with sophisticated event and alarming capabilities. Event Codes Note Extensions used

21 TIMS AND DOCUMENTATION Example of Modern Meters with sophisticated event and alarming capabilities. Some TIMS and meters are very limited however in identifying critical Meter Alarms.

22 EXAMPLE OF ADVANCED METER WITH CONFIGURABLE ALARMS This Meter has sophisticated alarm Configurability. The alarms are programmable as to their function and trigger points. MV90 including Interval Status alarms are also configurable.

23 CONFIGURING MV90 TIM SPECIFIC EVENTS New Functionality in MV90 XI SP1 + Patches provides the ability to customise validation processing TIM Specific Events now function with Ext Now supports Events and Status Alarms Each alarm can have processing rules defined. ( Ignore, Reject, Warn)

24 INTERVAL STATUS ALARMS Load Surveys in many advanced meters Have Status flags at the end of every interval. MV90 survey status has 7 Mappable Meter Flags Today's Advanced Meters can have Many Interval Status Flags CRC data error RAM / ROM Meter error Clock Error Alarm Watch Dog Timer Harmonic Distortion TIM developers with the meter manufacture try to map these alarms to the MV90 representation of these but this can be challenging

29 EXPERIENCES Meter setup and configuration can significantly effect the ability of a meter to present alarm conditions. Meter Firmware versions can significantly effect how alarms operate and are presented in MV90. TIM s Implemented functionality and operation determines success. Regression testing of older firmware is rarely undertaken by Manufactures. Validation testing of events and alarms is essential

30 SUMMARY Successful implementation of Advanced Events and Alarms Processing will: Provide considerable improvement in data delivery quality Reduce lost revenue Improve customer bill accuracy Provide better asset management capability

31 FUTURE - AMI MV90 is Playing a pivotal role in AMI The biggest Benefits of AMI is not reading meters For most utilities around the world Demand Reduction followed by additional energy services Interval data will be used to support these initiatives Additional interval statuses and events will be needed in the future to inform participants of the engagement of various initiatives.
