Global Challenge Focus beyond the here and now Executives must focus concurrently on 3 time horizons: 1. They must make the present business effective. 2. They must identify and realize the potential of the business. 3. They must make the present business into a different business for a different future. - Peter Drucker 7 Copyright 2010, SAS Institute Inc. All rights reserved.

Implement Advanced Metering System (In Progress) Implement a Grid Automation System(In Progress) Combine these into an Intelligent Grid Solution What is the Intelligent Grid? The Intelligent Grid links electricity with communications and computer control to create a highly automated, responsive and resilient power delivery system. EPRI 2005 CenterPoint Energy s Response: We are building the most sophisticated customer service system in the world. CenterPoint Energy Confidential 17

It is not the technology that makes a utility Smart it is the innovation in its application. Smart Utility Systems are founded on the basic principle of maximizing customer service. Smart Utilities are comprised of Informational and Operational technologies but they are neither independent or fully distinguishable within the system. Conduit (Communications) and Content (data) provide both the interoperability and the inherent value in a Smart Utility System. CenterPoint Energy Confidential 18

Smart Utilities operate in four dimensions: Device Data Determination Decision System State Demand Dynamics Consumer Behavior The Role of Data Analysis, Intelligence, and Events in a Smart Utility System is to support decision making in such a manner as to ensure the objectives of the system are consistently and predictably met. Visibility, Sensing, & Responding Across the Grid is Key we needed to create Intelligence through End-to-End Data Integration CenterPoint Energy Confidential 19

12 Points Scalability is critical for success. OSIsoft can run 20 million data streams (tags) of time series data at AMI 5 minute scan rates on a single Intel quad processor server. End-to-end visibility of the electric network is a significant value proposition that SmartGrid initiatives must capitalize on. OSIsoft is the preeminent historian supplier to utilities and interface with all the major SCADA vendor products. We re present in nearly all the largest utilities in North America. We see AMI data as an extension of operational data within the utility. SmartGrid Data needs context. We provide Analysis Framework (AF) which is a relational database meta-data and connectivity modeling environment that can associate PI Tags to elements in the AF models and link other applications such as GIS to the real-time source for advanced applications, event notification, and spatial viewing. AF scales to millions of elements in a network model on a single server. 37 Energy Central Webcast - 2010 Copyright 2010, OSIsoft Inc. All rights Reserved.

12 Points cont d Historical SmartGrid data is not useful operationally if the network model changes are not kept in history. AF supports versioning and maintains any changes as the network grows or is reconfigured. No one can sort through all this data manually. OSIsoft provides event notification, and analysis tools such as our Advanced Compute Engine which can associate stored exception rules to AF elements and PI Tags. No one should manually maintain the association of new meters added to the Head End systems and new AMI meter instances in the MDMS. We provide Auto Point Sync with our interfaces to automatically create new PI Tags and AF elements as meters are added. 38 Energy Central Webcast - 2010 Copyright 2010, OSIsoft Inc.

12 Points cont d Utilities must keep SmartGrid options open. The SmartGrid is evolving even as work begins. Today s decisions should not preclude alternatives in the future. OSIsoft builds interfaces (we have over 500 in our standard set today) to the major SmartGrid & AMI Systems and we ll continue to maintain these and create new ones as the market matures. We also are creating and will maintain Web Services to major Analytics, ERP and EAM systems such as SAS, SAP, and Maximo. OSIsoft is a secure infrastructure company. OSIsoft is all about secure infrastructure! We regularly submit new product releases to the Idaho National Labs and other agencies for thorough security evaluations. We are a primary generator and utility solution for meeting FERC CIP requirements for secure data management at utilities. SmartGrid should be considered strategic. We provide High Availability, Automatic failover, data buffering with every interface, and balancing of end user loading on the PI and AF servers. This is something we ve done for SCADA Operations Users and should be no less for SmartGrid users. 39 Energy Central Webcast - 2010 Copyright 2010, OSIsoft Inc. All rights Reserved.

12 Points cont d Systems should be supported by the experts. For our part, OSIsoft provides Managed PI with every Enterprise Solution we sell. Our 7x24 Network Operations Center monitors the health and welfare of our customers PI servers, interfaces, and other critical components of the SmartGrid system in a non-invasive manner. We automatically maintain version releases, notify of any failure in the system and can provide automatic recovery as well. No customer should have to count tags, interface instances, number of servers or number of client licenses. OSIsoft offers an Enterprise Agreement. This is unlimited use of our products for the purposes of SmartGrid. Customers should have access to industry knowledge. OSIsoft has created a Center of Excellence which we have staffed with people who have a wealth industry best practices and OSIsoft product knowledge. OSIsoft is not primarily a services provider but can be counted on to be part of our customers initial design and system architecture meetings to help make the most out of the products we offer. 40 Energy Central Webcast - 2010 Copyright 2010, OSIsoft Inc.
