System functionality over view of key functions
System functionality – over view of key functions

  • Full Pay As You Go functionality

    • Tokenless prepayment in the future enabling phone or internet based vending

  • Remote reconfiguration between credit and Pay As You Go mode

  • Customer budgeting information

  • Demand response

    • Critical peak pricing

    • Time of Use pricing

    • In-home display

  • On-line enquiries

    • Easier query resolution

  • Load profiling

    • 15 minute interval data collected remotely

  • “Last gasp” power outage notification

  • Compatibility with expected requirements of the OEB



Point to multi point advantages
Point to Multi-Point Advantages

  • For pay as you go applications, a single concentrator can control large geographic area of meters.

    • Long range communications -

      • Lower number of concentrators

      • Lower number of backhaul connections

      • Many 1000s of meter controlled by one base station

    • Does not require saturation installation of meters

      • Consistent with Pay As You Go being used for a proportion of customer base

      • System can start working as soon as the first base station is installed

    • Proven technology

      • Used in UK metering trials (100,000 units)

      • Rolled out in car tracking (Lo-jack)


Point to multi point
Point to Multi-Point

  • How it works -

    • Uses Ultra Narrow Band Telemetry (gives better S/N ratio)

      • Enables long range from low power, low cost endpoints

      • Endpoint uses Very Narrow band radios

      • Base Station uses wideband radio

        • Digital Signal Processing subdivides received signal into many narrow bands

          • Allows Base Station to receive many transmissions at the same time

    • “Find a Friend” feature enables one hop to cope with difficult sites


Assessment of typical installation
Assessment of typical installation

  • Assumptions

  • Base Station Antenna Height 10m (30ft.)

  • Meter Height 1.5 (3-4ft.)

  • Real world propagation study at SRP: on average, 3,800 meters controlled by each concentrator without load profiling

Radio performance
Radio Performance

  • Main Performance Criteria –

    • On demand read Performance


Radio performance1
Radio Performance

  • Prepay transaction

  • Demand response

    signalling

  • Power outages



Modes of operation
Modes of Operation

  • Four Modes of Operation -

    • 2-Way Smart meter with remote disconnect/reconnect

      • Meter fitted only

    • 2-Way Smart meter,remote disconnect/reconnect and budgeting information to customer

      • Meter and in-home display fitted

    • Pay-as-you-go

      • Meter and in-home display fitted

    • Demand Response

      • Meter and in-home display fitted

      • No disconnection (meter can be reconfigured remotely)


Meter specification
Meter Specification

  • Fitted with Radio Module and PLC as standard

  • Features –

    • Internal Contactor

    • Load Profiling

      • Stores 15, 30 or 60 minute profiles

      • Optional collection

    • Outage Detection

      • Sends ‘Last Gasp’ on power loss

      • Optional

    • Approval to FM 12S (network)


In home display specification
In-home display Specification

  • In-home display fitted with ‘Traffic Light’ system to show tariff level

    • Tariff band can be switched between different preset tariffs according to normal, peak or critical pricing

      • Global Broadcast message for tariff groups

      • Three lights on in-home display facia (green, amber, red) show tariff level


Base station
Base Station

  • Base Station Consists of –

    • Radio DSP Board

    • Single Board PC

    • Power Supply

    • Modem

  • Weatherproof Housing

  • Antenna

    • Omni directional antenna, length 3-4 ft

    • Height assumed to be 30 feet above ground

  • Backhaul

    • Any broadband connection (GPRS, ADSL, landline, fibre, etc.)


System specification
System specification

  • New development will build on existing features of AMS software

  • Either stand alone operation or integration with existing CIS

  • Will work within the competitive market in Ontario as part of Woodstock’s development with Systrends


Summary
Summary

  • New development offers highly featured system:

    • Pay As You Go, including tokenless

    • Demand response

    • On-line enquiries

    • Customer information inside the home

    • Compatibility with expected OEB requirements

  • Architecture is simple

    • Suitable for both saturation and partial roll-out

  • Initial roll-out with SRP

  • Available from late 2006
