Smart Meter National Programme

Working to rapidly establish its stated goal of pan-India universal electricity access, the government of India is enabling Smart Grids which can offer affordability and other benefits to consumers. The first step towards realising Smart Grids is the implementation of Advanced Metering Infrastructure (AMI).

The Smart Meter National Programme is being implemented to deploy smart meters across the country. The scheme is being implemented by Energy Efficiency Services Limited (EESL), a JV of PSUs under Ministry of Power.

Advanced Metering Infrastructure

AMI (Advanced Metering Infrastructure) is the collective term to describe the whole infrastructure from Smart Meter to two way-communication network to control center equipment and all the applications that enable the gathering and transfer of energy usage information in near real-time. AMI makes two-way communications with customers possible and is the backbone of smart grid. The objectives of AMI can be remote meter reading for error free data, network problem identification, load profiling, energy audit and partial load curtailment in place of load shedding.

Building Blocks of AMI

AMI is comprised of various hardware and software components, all of which play a role in measuring energy consumption and transmitting information about energy, water and gas usage to utility companies and customers. The overarching technological components of AMI include:

  • ​Smart Meters - Advanced meter devices having the capacity to collect information about energy, water, and gas usage at various intervals and transmitting the data through fixed communication networks to utility, as well as receiving information like pricing signals from utility and conveying it to consumer.
  • Communication Network - Advanced communication networks which supports two way communication enables information from smart meters to utility companies and vice-versa. Networks such as Broadband over PowerLine (BPL), Power Line Communications, Fiber Optic Communication, Fixed Radio Frequency or public networks (e.g., landline, cellular, paging) are used for such purposes.
  • Meter Data Acquisition System - Software applications on the Control Centre hardware and the DCUs (Data Concentrator Units) used to acquire data from meters via communication network and send it to the MDMS
  • Meter Data Management System (MDMS) - Host system which receives, stores and analyzes the metering information.

Benefits

The benefits of AMI are multifold and can be generally categorized as:

  • Operational Benefits – AMI benefits the entire grid by improving the accuracy of meter reads, energy theft detection and response to power outages, while eliminating the need for on-site meter reading.
  • Financial Benefits – AMI brings financial gains to utility, water and gas companies by reducing equipment and maintenance costs, enabling faster restoration of electric service during outages and streamlining the billing process.
  • Customer Benefits – AMI benefits electric customers by detecting meter failures early, accommodating faster service restoration, and improving the accuracy and flexibility of billing. Further, AMI allows for time-based rate options that can help customers save money and manage their energy consumption.
  • Security Benefits-AMI technology enables enhanced monitoring of system resources, which mitigates potential threats on the grid by cyber-terrorist networks.

Challenges

Despite its widespread benefits, deploying AMI presents three majors challenges that include high upfront investments costs, integration with other grid systems, and standardization.

  1. High Capital Costs:A full scale deployment of AMI requires expenditures on all hardware and software components, including meters, network infrastructure and network management software, along with cost associated with the installation and maintenance of meters and information technology systems.
  2. Integration: AMI is a complex system of technologies that must be integrated with utilities' information technology systems, including Customer Information Systems (CIS), Geographical Information Systems (GIS), Outage Management Systems (OMS), Work Management (WMS), Mobile Workforce Management (MWM), SCADA/DMS, Distribution Automation System (DAS), etc.
  3. Standardization: Interoperability standards need to be defined, which set uniform requirements for AMI technology, deployment and general operations and are the keys to successfully connecting and maintaining an AMI-based grid system.

AMI in the Indian Context

Modernizing India's grid system by investing in AMI promises to mitigate a number of strains placed on the grid due to growing demand for electric, gas and water resources. In particular, AMI will improve three key features of India's grid system including:

  1. System Reliability: AMI technology improves the distribution and overall reliability of electricity by enabling electricity distributors to identify and automatically respond to electric demand, which in turn minimizes power outages.
  2. Energy Costs: Increased reliability and functionality and reduced power outages and streamlined billing operations will dramatically cut costs associated with providing and maintaining the grid, thereby significantly lowering electricity rates.
  3. Electricity Theft: Power theft is a common problem in India. AMI systems that track energy usage will help monitor power almost in real time thus leading to increased system transparency.

Implementation of SMNP

The SMNP aims to replace India’s 250 million conventional meters with smart meters. The smart meters procurement will be procured by EESL. To begin with, the programme is initiated for the states of Haryana and Uttar Pradesh, states with AT&C losses as large as 28.42% and 34.36% respectively.

EESL's proven model of bulk procurement, aggregation of demand, and monetisation of savings will be the approach to roll out smart meters. This roll-out is proposed under the Build-Own-Operate-Transfer (BOOT) model, wherein EESL will undertake all the capital and operational expenditure with zero upfront investment from states and utilities.

EESL, on its investment, shall earn a nominal Internal rate of return (IRR) through a mutually agreed automated payback structure during the concession period, along with payment security mechanism from state governments and utilities.

Installation of these smart meters along with its associated communication and IT infrastructure will enable the DISCOMs to obtain real time energy consumption data of each consumer for subsequent analysis and will pave the way for initiating various smart measures by DISCOMs like Time Of Day (TOD)/Time Of Use (TOU) billing, prediction and management of peak demand, providing real time energy consumption data to consumer, prepaid billing facility, remote connection and disconnection of load, accurate billing, etc. Installation of these meters will also obviate the need for the meter reader’s visit to each and every consumer.
