EDISON INTERNATIONAL® SM Agenda CIM implementation History – Timeline CIM Implementation Project Example Current Activities CIM and the SmartGrid

EDISON INTERNATIONAL® SM Timeline 1999 CIM introduced at SCE – Integration Bus (IBUS) Project 2001 Asset Data Exchange between Work Management Systems (WMS) 2002 Asset Data data exchange between WMS and Outage Management System (OMS) 2003 Joined WG Model Driven Integration (MDI) methodology and MDI Workbench was introduced 2004 Work Order data to Ledger Accounting System (LAS) 2005 Joined CIM User Group 2005 Work Order Data exchange for Distribution Service and Pricing System (DSRP) using MDI methodology 2007 Device status data exchange between EMS and OMS 2007 Utilize Enterprise Architecture for CIM management and message creation 2007 AMI Standards 2009 Smart GRID Standards 2010 Smart Grid Information Management

EDISON INTERNATIONAL® SM Key Projects CIM implementation at SCE is evolutionary and project based 1999 : Integration BUS (IBUS) Project – Integrated Power Management System (PMS) and Outage Management System ( OMS). First CIM Project. 2001: Work Management System (WMS) Project – Used CIM messages on IBUS to exchange asset data between New Construction WMS and Maintenance & Inspection WMS. Required CIM extensions. 2002: OMS Project – Utilized the messages (asset data) available on the IBUS and applied XML with DTD. 2004: Ledger Accounting System (LAS) Project – Created CIM messages based on the CIM UML and utilized XML schema. 2005: Distribution Service & Pricing (DSRP) Project – Used MDI Workbench to manage CIM UML and automatically generate CIM messages 2007: Energy Management System (EMS) Project – CIM Message creation process is further refined based on the DSRP experience.

EDISON INTERNATIONAL® SM CIM Implementation Observations The initial implementation of CIM messages was costly and time consuming because: (a) CIM was not mature (b) Lack of SCE experience and (c) Lack of tools Reuse of existing messages on IBUS began to show benefits (OMS Project) Development and maintenance of CIM messages in XML document format using XML editor was extremely time consuming (OMS Project) Utilization of a tool such as MDI Workbench to create CIM messages from the CIM UML was very effective and saved time (LAS Project, DSRP Project) Understand CIM and applying proper CIM objects required experience and CIM consultants played the key role (LAS Project, DSRP Project) Need to have Enterprise approach to make CIM more effective (include application integration road map) Harmonization with other standards is critical (we’ll come back to this).

EDISON INTERNATIONAL® SM CIM/SDLC Methodology Based on the CIM implementation project experience, SCE CIM CoP (Communit of Practice) created the CIM implementation guideline for SCE related to the SCE System Development Life Cycle (SDLC)

EDISON INTERNATIONAL® SM SCE Smart Grid Vision Engineering design for resource integration Protection schemes Storage technologies System stability Real time power measurement Controls Analytics New materials Smarter tools Robotics Remote controlled devices Protective equipment Mobile applications Open standards base Extensible information and communication infrastructure Manage energy use Reduce carbon footprint Plug in electric hybrids Distributed energy resources

EDISON INTERNATIONAL® SM SmartGrid Architecture Drivers –System of everything Many new devices Large volumes of data –More integration –New technologies –Evolution over decades

EDISON INTERNATIONAL® SM SmartGrid Architecture Requirements –Common method of integrating components –Flexible to change over time New components Replace components –Stable complexity over time

EDISON INTERNATIONAL® SM SmartGrid Architecture Approach –System of systems –Service Oriented Architecture –Standards based (e.g. CIM, but that’s not all) –Semantic modeling Integration Database
