BPLC Introduction
Pilot wire used for transmission line protection is failing
17% failure rate according to an SEL study
Copper based wire is aging and deteriorating due to corrosion
Copper theft is an increasing problem Phone companies are phasing out the service
Many utilities lease the pilot wire lines
2Confidential Overview
erna ves are er or conven ona
Today only 9% of US substations are connected by fiber
Replacing pilot wire with fiber is very expensive and requires along deployment process
BPLC costs 10% of fiber and deploys in days compared to weeks
Amperions BPLC technology was developed jointly with AEPto solve this problem
Available now - no need to wait for fiber

BPLC Enables Better Protection
BPLC can be used to connect substations over transmission,sub-transmission and distribution lines
Transmission protection is implemented today with analog
relays using POTT and DCB schemes Protection schemes can be enhanced with the new generation of digital relays
that support multiple options including current differential
At the Distribution level coordination will become more difficult with more
22Confidential Overview
distributed generation and multiple terminal points Current differential is the most accurate and reliable
protection scheme But requires a reliable and fast communications channel
Fiber is too costly for lower voltage substations and notalways available BPLC is the next generation PLC and provides a ready-to-deploy cost effective
alternative

Summary
Over 622,000 transmission miles in the US require an investment of $36Band decades to deploy fiber to every substation
67% of the US transmission lines are at 138kV or below (sub-transmissioncategory) and are potential candidates for the BPLC technology
Deploying BPLC instead of fiber costs less than 10% and can beaccomplished in a much shorter timeframe
Substation automation requires a reliable broadband communications
23Confidential Overview
c anne to ac au cr t ca ata n rea t me
BPLC can be used to enable station retrofit projects that include upgradingsubstation equipment and supporting new smart grid applications
BPLC can also be used on distribution lines enabling accurate and costeffective current differential protection over short distances
Initial applications for BPLC will be pilot wire replacements, leased linereplacements, PLC upgrades, fiber extensions and fiber redundancy and
back up options
