1. Getting Ready for Advance Metering Infrastructure

2. AMI by definition Infrastructure of metering systems
Automates most of the metering centred repetitive activities
Collects granular consumption data to deploy dynamic pricing mechanisms
New payment and customer service options
Control of electrical load control within the home and or businesses to improve system diversity
The communications hardware , software, associated system and data management software that creates a network between advanced meters and utility business systems which allows collection and distribution of information to customers and the utility.

3. Is AMI same As AMR
AMR is primarily focused on the ability to collect data
Primary purpose of AMR systems is customer billing, and reduced costs of meter reading.
AMR systems typically comprise of static meters fitted with communication devices, communication network (media) as well as supporting software to manage the data.
AMI includes not only AMR, but, a system that collects time-differentiated energy usage from advanced meters.
Capable of providing information which enables utilities to provide demand response products & customers participation.
System supports other operational and customer service, e.g. outage management, connect/disconnect, customer load management etc.

5. 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 suit consumers’ needs; and
Interval data collection also helps to detect supply faults and respond to them more quickly – Faster outage detection and proactive restoration
Flexible billing cycle – Improved cash flow
Daily energy balancing for each DT
Transformer load management
Much more…………………
Other benefits –
Reduction in “high bill” complaints as the customer can be notified should their consumption rise above the credit threshold.
Opening avenues of consumer segmentation by capturing load profile data and doing load research.
Cost free meter re-reads
Flexible billing cycle, matching the consumer’s cash flow
Billing adjustmentsImproved metering accuracy.
Faster outage detection and proactive restoration.
Faster response to power quality problems like low voltage, neutral floating.
Reduction in false outage dispatches
Increased revenues from more rapid outage restoration (reduced loss of sales)
Daily energy balancing for each distribution transformer
Better data for use in optimizing planning and operations Voltage monitoring
Transformer load management
Reduction in load research costs
System planning benefits
Efficient revenue protection, immediate alarm in case of an attempted tamper resulting in immediate redress versus waiting for tamper discovery during monthly/ bi-monthly reads.
Reduction in uncollectible accounts: very few estimated bills which reduces re-billing.
Reduction in revenue losses from unoccupied premises owing to remote disconnect and monitoring kWh increments in unoccupied premises.

6. AMI Components Advance Meter In Home display
Suitable two way communication system
Network management system (NMS)
Meter Data Management (MDM)

7. 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 various communication technology.
The products are 1Phase, 3Phase,CT/PT operated meters.

8. AMI Components: In-Home Display
A device which details the usage data in a graphical and user friendly manner.
The inhome display device can be connected to a meter to create a Home Area Network via
Zigbee communication device
Hardwire connection between the meter and IHD
Secure Meters Limited 8

9. Network management System
NMS is a combination of Hardware and Software used to monitor 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 9

10. Meter Data Management (MDM)
The definition of a meter data management solution can vary based upon the implementation.
At a minimum, MDM provides a database repository and utility-specific business logic to:
Automate and streamline the complex process of collecting meter data from multiple meter data collection technologies
Evaluate the quality of that data and generate estimates where errors and gaps exist
Deliver that data in the appropriate format to utility billing systems
The critical role of an MDM system is to pre-process granular interval meter data at large volumes very quickly.

12. 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 network seems to be favorable for most of the areas.
More work needs to be done wrt - detailing out system functionalities, overall implementation and technology trials.

15. Planning AMI Deployment
Identify the current challenges of your business process.
Identify the future challenges that your business, your customer and the society may encounter.
Define AMI vision statement based upon the above.
Start with a pay-back analysis. Telescopically plan your AMI rollout keeping the most rewarding benefits in the first few phases.
Don’t re-invent the wheel; take suitable help from vendors and consultants as the cost of advice is insignificant in terms of benefits and avoiding rework.

16. Planning AMI deployment
Select communication technology and backend system on the basis of above mentioned parameters.
Define specification accordingly.
Bids to be called on the basis of clear understanding of requirement of system NOT only product.
Bids selection should be on the basis of complete system implementation.

17. Few Similar Projects executed
Northern Ireland: over 220,000 meters deployed
India: Largest grid metering project at MSETCL
