DPL - Metering Technology

• Automated Meter Reading (AMR)
• Read via radio frequency watt hours only,
  one-way only, mobile collector (truck) v. fixed
  network system
• Testing demand meters for use where access is an
  ongoing issue
• 100,000 installed on DPL system
• 15,000-25,000 additional to be installed in 2006
• Business case

DPL - Metering Technology

• Interval Meters
• Records electricity usage for defined intervals
  15 min., 30 min., 1 hour
• On DPL system communication via phone modem
  hard line or cellular
• Addressed in tariff sheets D7, G9
• 640 installed on DPL system for Electric Choice
  customers and internal use.

Meter-based Programs

• Electric Choice
• Certified Retail Electric Suppliers (CRES) can
  offer time-based rates in response to customer
  demand
• Host utility time-based rates may slow the
  development of the competitive marketplace
• Other Meter-based Programs
• Rules governing access for Electric Choice
  created opportunities for other meter-based
  competitive services

PJM Demand Response Programs

• Emergency Load Response Program
• Participants reduce load during emergency
  conditions in exchange for payment
• Economic Load Response Program
• Economic-based program that pays customers to
  reduce consumption when PJM LMP prices are high
  effectively viewing negative load as a generation
  source

PJM Demand Response Programs

• Economic Load Response
• Customers join PJM or use Curtailment Service
  Provider (CSP)
• 20 CSP listed for all PJM states or list Ohio
  specifically
• CI customers can enroll with CSP who is not the
  generation service provider no certification by
  state or utility
• No PJM fee if customer enrolled by CSP
• Real Time Program has no penalties for
  non-performance

Time-based Rates

• Time of Use
• Critical Peak Pricing
• Real-time Pricing

Time-based Rates

• Time of Use
• Rate differs by time of day, day of week and
  season
• Pre-established prices
• Typically on-, off- and mid-peak periods
• Significantly shift energy use to off-peak hours
  savings
• Inability to shift energy use higher cost
• Not for everyone - Schedule Advantagers and
  impact to Rate Class

10
Time-based Rates

• Critical Peak Pricing
• Based on TOU concept with limited,
  condition-based critical periods
• Pre-established prices for non-critical days
• Market prices during critical events
• High degree of automation required to make
  program effective, workable for customers

11
Time-based Rates

• Critical Peak Pricing (continued)
• 2-way communicating interval meter
• Smart thermostat
• Linked load control devices to manage targeted
  equipment (for example, water heater)
• Level of required automation is uneconomic

12
Time-based Rates

• Real-time Pricing
• Rate differs hourly
• Based on Dayton Zone LMP? AEP-Dayton Hub?
• Real Time Market?

Time-based Rates

• Real-time Pricing
