Public company traded on the New York Stock Exchange (CNP) Headquartered in Houston, TX Operating 6 business segments in six states Electric transmission and distribution Natural gas distribution Interstate pipelines and natural gas gathering Serving 5.4 million electric & gas customers $20 billion in assets $8.7 billion in revenue 8,843 employees Over 130 years of service to our communities Minneapolis Little ock Houston To be recognized as America s Leading Energy Delivery Company and more Natural Gas Distribution Interstate Gas Pipelines Electric Transmission & Distribution

4 WHO IS CENTEPOINT ENEGY ELECTIC? Houston Electric Division (CEHE) Houston (4th largest city in the US) Houston Metro Area (6th largest in US) 5,000 square mile service area Approximately 2.1 million electric meters Houston Electric Delivers 77 Megawatt hours yearly for about 100 certified etail Electric Providers Transmission and Distribution System 3,754 miles of transmission lines 48,232 miles of distribution lines 233 substations Electric Challenge: Effectively monitor and control millions of meters, line devices and miles of delivery wire which, if laid end to end, almost circle the earth twice around the equator

7 CNP S SMAT GID: TWO PATS 1. Advanced Metering System (AMS) 2.2 Million Advanced Meter System (AMS) meters to be installed during at a cost of $540 million inclusive of a $150 million DOE fund contribution AMS will provide for two-way communication between customers and market participants (i.e., EP, QSE, Aggregators, Authorized 3 rd Parties, and TDSPs) 2. Intelligent Grid Initial implementation of Intelligent Grid (IG) by 2012 at a cost of $100 million inclusive of a $50 million DOE fund contribution IG is comprised of system sensors, monitors, high-speed communications and data-trending software designed to real-time insight and analysis of distribution system to provide greater reliability, safety, choice and flexibility Vision: CNP seeks to enable the Texas electricity market to extract the full functionality of the Smart Grid by supporting individual management of electricity consumption, fostering adoption of market-driven programs and achieving maximum operational readiness and efficiency 7

8 CNP S VISION FO THE SMAT GID Advance Metering Systems (AMS) will provide: 1. Detailed information on usage, 2. Significantly faster and less intrusive service for reads, 3. Faster remote turn on/off, 4. Meter checks for functionality working, removal, tilt 5. Two-way communication between customers and market participants (i.e., EP, QSE, Aggregators, Authorized 3rd Parties, and TDSPs) 6. Back office systems to analyze, retry for missing, estimate accurately, prepare for the market 7. Everyman s portal to access the data Cost: 2.2 Million Advanced Meter System (AMS) meters to be installed during at a cost of $540 million inclusive of a $150 million DOE fund contribution 8

11 CNP S INTELLIGENT GID (IG) VISION Intelligent Grid is comprised of 1. System sensors & monitors, 2. Field communications 3. Data-trending software to provide real-time insight the distribution system 4. Provide greater safety and reliability 5. Provide proactive customer notification of planned and unplanned outages 6. Improve customer satisfaction Cost: Initial implementation 15% of CNP territory with IG by 2012 at a cost of $100 million inclusive of a $50 million DOE fund contribution 11

12 INTELLIGENT GID What Should We Do? Goal 1 Detect fault Goal 2 Isolate the faulted section Goal 3 Locate the cause Goal 4 Characterize fault type Goal 5 Monitor Assets How do we do it? with TECHNOLOGY Accurate sensing High esolution Event ecording Automated Switching Devices emote Control estoration Automated Fault location Fault characterization IG Self Diagnostics

24 FUTUE FUNCTIONALITY BEING EXPLOED 1.

Customer Notification for unplanned (and eventually planned) events Notify customers via , text or phone call of unplanned or planned outage situation with status updates, pending service orders, emergency situations 3. emote monitoring and control of street, guard and parking lot lights Notify Have the sensor notify a central control of lamps not working or lighting during the day. Turn off or dim certain lights at times desired. Measure and bill on individual lamp usage 4. Automated remote phasing determination We have an idea but are stuck on technical functionality. Most utilities seem to be brute forcing via field trips. Is anyone doing automated remote phasing determination? Please see me afterwards. 24

25 FUTUE FUNCTIONALITY BEING EXPLOED TAKE ADVANTAGE OF THE INFASTUCTUE Others (not enough time): 5. Notification Transformer and facility overload predictive analysis Aggregate 15 minute loads to determine peak loading levels and duration to determine if transformers (and potentially other equipment) should be replaced prior to failure 6. Sensing plus usage analysis to quickly determine diversion eceive a notice from the meter about unplanned outage with a tilt and then usage drops off from norm, investigate tampering Numerous additional initiatives being considered taking advantage of the Smart Grid infrastructure, functionality and data 25
