Getting Ready for Advance MeteringInfrastructure
AMI by definition
•Infrastructure of metering systems
•Automates most of the metering centred repetitiveactivities
•Collects granular consumption data to deploy dynamicpricing mechanisms
•New payment and customer service options
•Control of electrical load control within the home and orbusinesses to improve system diversity
The communications hardware , software, associated system anddata management software that creates a network betweenadvanced meters and utility business systems which allows collectionand distribution of information to customers and the utility.
Is AMI same As AMR
AMR is primarily focusedon the ability to collectdata
Primary purpose of AMRsystems is customerbilling, and reduced costsof meter reading.
AMR systems typicallycomprise of static metersfitted with communicationdevices, communicationnetwork (media) as well assupporting software tomanage the data.
AMI includes not only AMR,but, a system that collectstime-differentiated energyusage from advanced meters.
Capable of providinginformation which enablesutilities to provide demandresponse products &customers participation.
System supports otheroperational and customerservice, e.g. outagemanagement,connect/disconnect, customerload management etc.

Benefits of AMI - Utility
•Elimination of manual metering capital costs
•Fewer meter reading related issues and call center traffic.
•Utilities can have innovative time-of-use price offers to suitconsumers’ needs; and
•Interval data collection also helps to detect supply faultsand respond to them more quickly – Faster outagedetection and proactive restoration
•Flexible billing cycle – Improved cash flow
•Daily energy balancing for each DT
•Transformer load management

AMI Components
•Advance Meter
•In Home display
•Suitable two way communication system
•Network management system (NMS)
•Meter Data Management (MDM)
AMI Components – Advance Meter
•Electronic meter with
•two way communication,
•time differentiated registers
•price based demand
•connect / disconnect
•load Control,
•interface with In-Home devices.
•AMI / Smart Metering with variouscommunication technology.
•The products are 1Phase, 3Phase,CT/PToperated meters.
AMI Components: In-Home Display
•A device which details the usage data in a graphical anduser friendly manner.
•The inhome display device can be connected to a meterto create a Home Area Network via
–Zigbee communication device
–Hardwire connection between the meter and IHD
Secure Meters Limited
Network management System
•NMS is a combination of Hardware and Software used tomonitor and administer a network.
•This NMS needs to be linked to the ERP system
•What this system needs to do?
–Manage connect/ disconnect
–Manage alarm, events and other notifications
Meter Data Management (MDM)
•The definition of a meter data management solution canvary based upon the implementation.
•At a minimum, MDM provides a database repository andutility-specific business logic to:
–Automate and streamline the complex process of collecting meterdata from multiple meter data collection technologies
–Evaluate the quality of that data and generate estimates whereerrors and gaps exist
–Deliver that data in the appropriate format to utility billing systems
•The critical role of an MDM system is to pre-processgranular interval meter data at large volumes very quickly.

Technical Architecture / Landscape
AMI in India
What are the main drivers –
Demand shortage
Theft management
Load control
System automization
Better system economics
Govt. has taken a step forward in long term AMI direction,by defining a sort of similar system in RAPDRP.
Combination of RF, DLC, GPRS communication networkseems to be favorable for most of the areas.
More work needs to be done wrt - detailing out systemfunctionalities, overall implementation and technology trials.

Planning AMI Deployment
Identify the current challenges of your business process.
Identify the future challenges that your business, yourcustomer and the society may encounter.
Define AMI vision statement based upon the above.
Start with a pay-back analysis. Telescopically plan yourAMI rollout keeping the most rewarding benefits in thefirst few phases.
Don’t re-invent the wheel; take suitable help fromvendors and consultants as the cost of advice isinsignificant in terms of benefits and avoiding rework.
Planning AMI deployment
Select communication technology and backend system onthe basis of above mentioned parameters.
Define specification accordingly.
Bids to be called on the basis of clear understanding ofrequirement of system NOT only product.
Bids selection should be on the basis of complete systemimplementation.
