Automated Meter Reading (AMR)
• Once meter data is available in electronic form, it becomes feasible to add
communications to the meter, allowing the meter to use automatic meter
reading (AMR) to access data remotely via the communication link.
• Meter manufacturers have developed different system architectures for
remote reading, broadly classified as walk-by, drive-by, or networked
systems.
• Data can be measured and stored at specific intervals, allowing the utility
to offer price plans based on time-of-day of usage. This allows consumers
to save money by running major appliances, such as washers and dryers,
during lower-cost, off-peak periods; and utility companies can avoid
building new power plants because less capacity is required during peak
periods.

AMR to AMI
Initially, replacing manual reading with AMR systems was seen simply as a
way to reduce labour costs, but this is changing as the industry recognizes
that AMR allows utility companies to conveniently provide higher order
benefits and services, such as real-time pricing to promote better energy
efficiency, instant reporting of fault detection, and more accurate data for
profiling usage within the network. AMR is sometimes replaced with
Advanced Metering Infrastructure (AMI) to highlight the evolution from
simple remote meter reading. AMI system can be implemented using
technologies ranging from satellites to low-cost radios.

Features of Smart Meters
•
•
•
•
•
•
•
•
•
•
Remote Connect / Disconnect
Meter functionality to operate as normal from remote perspective when
disconnected
Meter Configurations Load limiting capability with disconnect when set load
is crossed and reset button to reconnect
Remotely Configurable for Tariff and energy consumption calculation, and
other functionality to be date bound – ‘effective from’ or ‘effective to’ where
appropriate
Remote load setting
Capability to store meter data for specific duration with sufficient on-board
memory (2 months of 30 minutes / 15 minutes interval data)
Provide on- demand readings
Send readings according to schedule configured
Event of meter diagnostic alerts, network parameters, tamper
Data items stored within the meter, e.g. serial number, year of manufacture,
etc,

15
Features of Smart Meters – Data Security
• Include data security measures/protocols to protect data from fraud,
tamper and unauthorized access
• Issue alerts when unauthorized access is detected
• Meter data, events, fault and tamper logs accessible only by access levels
• Sent events and alerts both based on event and as configured schedules
• Appropriate data security protocols to ensure data is protected during
communication
• Provisions to ensure meter functionality configuration is subject to
appropriate access control

Meter Data Acquisition System
• Communication with Smart Meters through GPRS / PLC
•
•
interfacing with GPRS based smart meters
communicating smart meters based on IEC 62056 / DLMS protocol
• Data collection facility on Scheduled frequency, considering
•

Meter Data Management System
• Meter Data Repository – the database that houses the meter reading
data.

one location, the MDMS brings
simplicity and value
• By maintaining historical changes
over time, reporting and trending
becomes much easier

Overview
Smart Metering / Grid is a complex exercise. There are challenges related
with the right products or suppliers’ availability in the Indian market,
infrastructure availability, regulatory framework etc. In view of the same,
it has been decided that this initiative will be carried out in a phased
manner.
• Pilot Smart Grid Project ADR-AMI integration is in progress. In this
project Auto Demand response (ADR) and Advanced Metering
Infrastructure (AMI) will be integrated with each other, connecting
around 250 Industrial and Commercial Consumers through Smart
Meters. Deployment is in progress at Lawrence Road and Narela Industrial
areas.
• Proof-of Concept on Smart Metering using Power Line Communication
over LT lines (LT-PLC) has been done thro’ underground. Trial is in progress
on composite network also.
• This initiative will help TPDDL, in successfully demonstrating the benefits
of AMI and Smart Metering in reducing peak demand and respond to any
emergency situation related to power availability.
