What is Smart Metering?

• Many different definitions
• Siemens says that Smart Meters “enable” the last mile

– Intelligent monitoring of consumption

– Bi-directional data transmission

– Increased security of supply and higher efficiency

– Variable tariffs dependent on overall consumption and grid load

What Smart Metering Offers

• Provides detailed information on what is being consumed/delivered on a quasi-real-time basis

– Supports in-home displays

• Provides the data for consumers and utilities to make smart energy choices
• Improves utility operations by (for example):

– Identifying where energy is being consumed

– Helps localize outages

– Highlights areas with possible energy theft

• Helps customers deliver energy to grid
• Eliminates the need to change meters when services or features are modified (such as time-of-use)
• Provides a pathway to the Smart Grid

What we can do with Smart metering Applications. Below are few application derived from available large chunk of data from AMI system.

Monthly meter reading – total consumption

• Off-cycle meter reading – total consumption
• Monthly kW demand read
• Static time of use (e.g., peak, off-peak, shoulder)
• Real-time pricing (passive load control)
• Curtailment or interruptible service
• Power quality monitoring
• Outage detection

Advanced Metering Infrastructure (AMI) is a comprehensive, integrated collection of devices, networks, computer systems, protocols and organizational processes dedicated to bi-directionally distributing highly accurate information about customer electricity and / or gas usage throughout the utility and back to the customers themselves.

Key AMI Capabilities:

• Record customer consumption and meter event information hourly   or more frequently
• Remote disconnection and reconnection
• Outage detection
• Quality of supply monitoring
• Demand limiting
• Communication interface to in-house displays, direct load control   equipment etc.
