What is AEP’s grid. SMART Initiative? sm • A multi-year initiative that includes a suite of customer programs and advanced technology initiatives that will transport us into a new era of energy delivery and customer service. • grid. SMARTsm components, include: – Customer programs: Energy efficiency and conservation opportunities and options. – Distribution grid management and advanced metering: New technologies that improve service reliability by quickly identifying and possibly reconfiguring the distribution circuit to minimize the impacts of certain service interruptions; advanced data and communications systems that provide customers and AEP with real-time use and pricing information to facilitate usage decisions that immediately impact the monthly electric bill; and installation of new technologies that will allow AEP's facilities to accommodate customers' new technologies. – Distributed resources: Energy storing and energy producing devices located throughout the distribution system that respond quickly to local needs and conditions for greater service reliability. – Internal efficiencies: AEP demonstrates its commitment to grid. SMART by implementing numerous efficiency improvements within its own operations - from lighting efficiencies in office buildings to variable-speed motors in power plants. 3

Meter Status • WSDL Location: http: //xxxx/grid. Smart. Adaptationwar/Meter. Status. WService? wsdl • Description – The purpose of this service is to provide a "ping" capability, allowing back-office applications to contact a device in the field and confirm if it is energized. The operation is asynchronous in nature, in that back-office applications must "provision" a job(s) in the AMI system(s) to perform the meter status operation. When the AMI system(s) complete processing the request, a call back service in the back-office application (called a "deliver" message) will return the results. – This message supports requesting Meter Status operations for multiple devices. For the Indiana Pilot, the element will not be supported. – The Response type for this service contains a standardized Acknowledgement message. Embedded in the acknowledgement is a Context. ID field, which represents an AMI head-end system agnostic identifier for the requested operation, along with a timestamp marking when the operation was started. If the operation was targeted as multiple devices, a collection of elements is also returned, indicating the success/failure to submit jobs to the AMI system for each unique device identifier (m. RID). 8

How do you to prepare yourself and your companies? • Educate yourself – EPRI Resources – Grid Interop 2007 http: //www. gridwiseac. org/historical/gridinterop 2007/forum_p apers. aspx • Join the UCA - http: //www. ucaiug. org/default. aspx – Join the CIM UG - http: //cimug. ucaiug. mobi/default. aspx – Read IEC 61968 – It will be available • Purchase a Tool that you can actually look at the CIM – Power. Point's don’t tell the entire story • Figure out how you change your organization to be a Semantics friendly, model driven integration, standards involved Utility. • Get Buy in from the Right Levels – you will need to be an Educator/Advocate of Utilizing CIM in your company 17
