5PHI Smart Grid - Key Components
- Putting decision making in the hands of customers
- Provide improved information, programs and
pricing options that will allow customers to make
informed energy choices - Give customers better information about their
service and use - Automatically accommodating changing conditions
- Isolate fault, expeditious automatic restoration
- Reroute power flows, change load patterns,
improve voltage profiles - Minimal workforce intervention, auto notification
for corrective actions and maintenance activities - Design and operate with greater efficiency
- Better asset management optimize grid design
- Optimized grid operations
- Greater reliability and security
- Promote green energy initiatives and enable
distributed, renewable energy resources to
participate
Many of these key components focus on energy
efficiency and conservation while improving
customer service.

10Connect/Disconnect Switch Example FOCUS
AX-SDRelay Motor Sub-Assy
- Proven technology - same relay used in AMPY
prepay meter - Contact actuation is cam-driven by relay motor
- Cam-drive provides higher force compared to
spring contacts on solenoid disconnect switches. - High contact force greatly reduces welded
contacts due to surge currents.

11Connect/Disconnect Switch ExampleLine/Load
Blade Assemblies
- Copper current blade width 5/8
- Line side of relay has 3 flexible contacts
- Contact material is silver (low resistance)
- One-piece current coil construction no welds
- Load side of switch has fixed silver contacts

12Connect/Disconnect Switch Example Motor Control
Board
- Solid-state low voltage DC motor drive
- Energy to activate switch stored in capacitor
no large current surge - Switch can be reliably activated on any test
board - Switch activation works under low-line
conditions unlike AC solenoid designs

13Benefits
Quantified Benefits in Business Case Substitute
a remote disconnection and reconnection for a
field visit on a past due account. PHI
completes about 135,000 field visits per year
with about 53,000 cuts and 22,000 field
collections. Close to 90 of the field visits
are to residential premises. Substitute a remote
disconnection and reconnection for a field visit
for a customer requested turn-on or turn-off.
Two of PHIs three operating companies follow a
hard disconnect policy. As a result about 33,000
labor hours per year that are expended on field
visits to conduct this type of work could be
eliminated. Other Potential Benefits Reduction
in uncollectible expense and aged receivables by
disconnecting service at lower account balance
levels. For example, automatically disconnect
past due accounts when they reach some threshold
such as 200 dollars rather todays balances
which, on average, run in the range of 900 to
1,100 for residential customers. Remotely
configurable load limiting. Prepaid
functionality, for example in college areas where
a parent could pay for power for a semester up
front.

16Labor Implications
- Will only need field collection personnel for the
AMI meters without the remote disconnect switch
(greater than 200 AMP) - Opportunity to increase field personnel dedicated
to revenue protection investigation work. - May need fewer back office clerical personnel but
may want to add more decision support analysts.
17Regulatory Issues
- Requirement or past practice of collecting past
due accounts at the customers premises or
otherwise visit the customers premises prior to
disconnection. - Perceptions of impacts on low income customers or
other customers with financial hardships. - Pizza box story
18Defining Revenue Assurance
RPS
- Administrative losses uncollected debt, customer
on wrong tariff - Commercial losses theft from known accounts,
unmetered accounts - Technical losses Line losses, pipeline leakage
and vented gas

20How does RPS work?
Revenue Investigator can filter candidate list by
different parameters such as of tampers,
deviation from baseline consumption, and more.
Nightly automated process analyzes consumption
data and compares effective usage to baseline
usage, then merges results with tamper
information.
Sort suspect list by route, ZIP code, and more to
create report, or export file for field
investigation.
