Distribution Operations of the Future
AEP Ohio believes that utilities must begin preparing their businesses for a future state that integrates many technologies not present today, and requires a more advanced state of monitoring, communications & control.

gridSMART Capabilities & Requirements
● Advanced Meter Infrastructure (AMI) Network Two way communications network with sufficient bandwidth to support AMI
and future gridSMART applications Remote connect/disconnect on all residential meters Downloadable firmware in each meter ANSI standard data tables Revenue protection advanced reporting Communication path to a Home Area Network (HAN) Standard protocols used and supported Minimum of 128-bit AES encryption Radio must have upgradeable firmware All meter tables are extractable

gridSMART
AEP Ohio - Proposed Deployment Strategy
● Overall Plan District by district roll out over a seven year period
Capability for 100% remote reconnect/disconnect on all residential meters (200 amp and below)
Capability for 100% interval data recording
Deployment of Web Portal
Deployment of Distribution Management System
Deployment of Meter Data Management System
Distribution automation projects to follow the same district deployment path
SCADA at all distribution stations Automated switches and reclosers for Urban, Large Rural and Medium Rural
circuits Small Rural circuits would not be automated at this time Automated capacitor banks for monitoring and control

gridSMART
AEP Ohio - Proposed Deployment Strategy
● Post-deployment Areas of Focus Home Area Network Equipment
Smart thermostats Load controllers In-home displays
Customer Information System Replacement/Augmentation AEP’s core CIS to be extended by the addition of integrated components Future pricing models will require new billing capabilities
● Effective Financial Modeling Will Require New Thinking McKinsey Model will be used to assist the PUCO for cost/benefit order of
magnitude and utility comparison purposes Results will be based on 20 YR net present value, which may not be
appropriate for all investments More appropriate models should be used for regulatory recovery
Need to determine how to value the benefits yet to be uncovered Distribution grid management and analytics Reliability improvements T&D efficiency gains

AEP Ohio – Distribution Grid Management Overview
● Benefits Operating Cost Benefits
Improved safety Less field trips Reduced fuel and vehicle expenses Reduced restoration expenses Capital avoidance due to proactive maintenance
Reliability Improvements Reduced customer outage minutes - What is the value? Varying levels of automated system reconfiguration during
disruptions Real time knowledge of system performance
T&D System Efficiency Improved volt/var management Reduced losses on the distribution system caused by our design
practices and how we operate the system Improved capital investment decisions based on system
intelligence
Distribution technology system design, costs and benefits are still being refined; we don’t know what we don’t know

gridSMART Recommended Next Steps
• City Scale gridSMART Initial Phase• AEP Ohio will continue technology evaluations, make initial
selection(s), and secure pricing in 2008• AEP Ohio recommends continued dialogue followed by
filings that will lead to regulatory approval to install both AMI and distribution automation technology with implementation beginning by early 2009
• Evaluate results and determine appropriate pace of future deployments
• PUCO approves cost recovery for AMI implementation for all of AEP Ohio which will result in all meters being converted to AMI by 2015
• Development and regulatory approval of new demand response and tariff offerings in conjunction with the AMI deployment
