Utility Meters view of DR DR from a utility
meter perspective

• Utility Meter provides the measurement and data
  that can support DR programs
• Meter is normally the responsibility of the
  regulated distribution utility
• NU Example
• Dave Scott Manager Meter Engineering Systems
• Responsible for distribution, transmission
  metering related systems in CT and MA
• Billing, ISO-NE Settlement, ISO-NE Control
• Customer and Supplier metering needs
• To help support DR and Restructuring, NU offers
  metering choices for Customer and Suppliers

Silver, Gold and Platinum NUs Meter/Data
Options supporting DR

• Flex-AMR Standard Silver service
• Reliable monthly reads via AMR technologies
• Gold metering service options (for a fee)
• Incremental cost paid for by customer that
  benefits
• Advanced Metering (Interval Metering read daily)
• Hourly Data used for Settlement
• Customer energy management system interface
• Real time load pulse output
• Interfaces with EMS and/or ISO-NE DR equipment
• Platinum data service options (for a fee)
• MDATA On-line Internet access to meter load data

6
Platinum ServiceNear Time Internet Meter Data

• NUs - MDATA Online Data Services
• Near Time data up to midnight the previous day
• 24-Hour Profile for the last 13 months
• Peak day Demand
• Daily Peaks and/or Totals
• Detail 15 minute resolution profile
• Statistics
• Download data
• Access with ID/password using any standard web
  browser

MDATA Supports DR Providing Load Profile Data to
the End-User

• Managing load
• First the End-User has to understand their load
• MDATA provides that means
• Then they can make decisions to manage loads
• Demand Response is one of the customers/suppliers
  drivers for managing loads
• Improve efficiency to lower energy/equipment
  costs
• Customers shopping for suppliers
• Compare usage to standard load curves
• Get better information for smarter shopping
• Some suppliers also use this data
• Read-Only access to meters

MeteringFunctions Recording and Communications

• DR usually requires some level of recording and
  communication from the meter
• Recording kWh Usage vs Time
• Interval data (Recording Data)
• Hourly data
• 15 Minute data
• 5 Minute data
• Profiled from standard load shapes
• Based on rate, day and monthly kWh usage
• TOD
• On-Peak, Off-Peak, Shoulder-Peak

11
MeteringFunctions Recording and Communications

• DR requires some level of recording and
  communication from the meter
• Communications Monthly to Real-Time data
• Manual - Sneaker-Net (Meter Readers)
• Daily Communications
• Via Phone Modem in the meter
• PLC and/or Private Networks (IE DCSI, CellNet)
• Wireless Public Networks (IE Analog, Paging,
  Digital)
• Near-Time Communications
• E-Mail frequent phone calls
• Real-Time Communications
• Load-Pulse output
• Telemetering (load-pulse interface with ISO)
• RS232, Modbus
• Ethernet connection

12
Data FlowPurpose Control vs Settlement

• DR Data frequency/timeless is dependent on the
  purpose of the data
• Control
• ISO Operations and Control Center
• Near to Real Time Data needed
• Interval Real, 5 minute or 15 minute
• Settlement
• Billing and Payments
• Day later
• Months later

13
Technology vs NeedMatching Metering/Data to DR
programs

• Example ISO-NE Programs
• Real Time Demand ( Value)
• Blocks of load expected to reduce in 30 or 120
  minutes
• ISO-NE Control needs to see load reduction within
  5 minute of actual load reduction Settlement in
  36 hrs.
• Real Time Price ( Value)
• Volunteer load reductions based on price signals
• No Control monitoring Payments based on actual
  hourly recorded load reduction from base reported
  within 36 hours (Low Tech) or 90 days Super Low
  Tech).
• Real Time Profile ( Value)
• Required load reductions based on ISO events
• No Control monitoring Payments based on
  statistical data reported within 36 hours.

FutureCommunications and Control

• Improved communications for control purposes
• Either ISO-NE Control Room or Control of
  Customers Loads
• ISO-NE Control Room (5 minute data available to
  ISO during event)
• Public network communications directly from the
  meter
• Digital Wireless technologies
• Lower data cost with digital 1XRTT, GPRS systems
• NU is piloting this technology with NERTEC and
  Schlumberger meters
• Internet Communications
• NU is piloting this technology with Power
  Measurement meters
• Control of Customers Loads
• Via Internet (Provider or customer control)
• NU is working with Lanthorn and Itron
• See example
