Available in the FUTURE Support for plug-in hybrid electric vehicles Consumer remote control of thermostats and appliances (HAN) Energy management systems 6 Some Components of our Intelligent Grid (IG) Combined with back office computer systems, our IG technology, when fully deployed, will automatically identify the location of power outages, isolate faulted sections of the main feeder portion of the network and re-route power from other sources, essentially automatically restoring as much of the system as possible. 14 2010-2014 Deployment of the Intelligent Grid IG Infrastructure
Automate up to 29 substations Smart Relays & Transformer Monitors 18 substations complete through 9/30/12, remainder by YE 2013 Install about 625 intelligent grid switching devices (IGSD) on about 230 distribution circuits Provide Remote/Automated Switching Capabilities Include Distribution Line Monitoring, Dual Communications Capabilities, Physical & Cyber Security Provisions, etc. 293 IGSDs installed through 9/30/12, 374 by YE 2012, Remainder in 2013 Implement an Advanced Distribution Management System (ADMS) Leverage AMS Communications Investment Common telecommunications backhaul network for AMS and IG AMS meter data feeds outage analysis module of ADMS While Phase 1 covers about 15 percent of CenterPoint Energys service area, some of the improvements will benefit consumers in the entire system. 15 Consumer Benefits of Intelligent Grid View demo at YouTube.com/CenterPointEnergyVid
Initial Benefits More precise identification of outage locations, resulting in faster restoration of electric service Reduction in time required to perform circuit switching to isolate fault Long-term Benefits Improved reliability and faster restoration, especially during major weather events Enhanced and improved customer communications and notifications
Following Hurricane Ike in 2008, the Mayors Task Force concluded that a smart grid offers the best return-on-investment for improving grid resilience and enabling storm recovery system-wide and that [f]inding the means to accelerate CenterPoint Energys deployment of intelligent grid technology in the Houston area is the Task Forces strongest recommendation. It has been estimated that full intelligent grid 16 functionality could improve reliability by up to 30%.

Consumer / Data Privacy Statutes and rules state that meter data belongs to the customer Market rules also recognize various market participants need for meter data in order for the market to function Usage data, including historic data, is available to customer, TDU, and the retailer of record Data is available to other parties only with customer permission Personal information such as social security number is not in the system 15 Components of Cyber Security Strategy
Prevention Detection Identify anomalous behavior Detect malicious code and other events Gather digital evidence Response Reduce risks and vulnerabilities Intervene and stop attempted occurrences Mitigate effects
Address short-term direct effects of incident (public safety et al) Recovery Restore normal operation & Address issues CenterPoint Energys Cyber Security Perspective Collaboration is Key: cyber threats are evolving and require collaboration, information sharing with the government and continued collaboration with the industry to effectively protect the nations critical infrastructure. Our goal is to focus our resources on facing the cyber threat. Our Cyber efforts parallel our corporate philosophy:
Public Safety Energy Delivery Reliability Customer Service Cyber Security Efforts We are entrenching a strong cyber security culture: Protection of customer privacy, and other essential information Cyber security is incorporated into our process, procedures, and operation through various mechanisms over time We have evolved from perimeter defense to defense-in-depth
and maturing to an agile defense posture Established talents and tools to assist our current efforts Continuously educating our workforce Be aware and be the first line of defense We recognize our efforts need to evolve to match ever-changing threats Enhancing system resiliency to cyber incidents Identifying and coordinating activities with the right stakeholders Cyber Security Participant Observations Shared Goals Risk Based Approach Information Sharing and Situational Awareness Leveraging Tools and Techniques Security Clearance
Cyber Security Regime Incident Management Collaboration 24 Whats Next? Smart Meters Are Just The Beginning Smart Meters Smart Meter Texas Portal HAN Devices Smart Appliances Phase 1: Customer Insight Intelligent Grid Price control / load control Electric vehicles Phase 3: Customer Co-Creator of Value 2010
We take seriously the responsibility of protecting our customers, employees, assets, and communities in which we operate, and thus cyber security is a top priority for CenterPoint Energy. We also recognize the importance of critical infrastructure to our national security. Because cyber threats are constantly changing and evolving, we support voluntary programs that encourage partnership, collaboration, sharing of information and technology, and the preparedness necessary to mitigate and respond to the ever changing nature of cyber attacks.

Meter testing by the manufacturer at the plant and by CenterPoint Energy Comparison testing of smart meters vs. traditional meters Independent third-party accuracy tests Digital photos of removed meters to verify final readings Individual smart meter accuracy tests upon customer demand Independent meter software review Comprehensive cyber security program based on national standards
Energy usage data belongs to the consumer: shared only when authorized in writing by the customer or authorized by regulatory authorities as necessary to conduct business (such as for billing). Most likely cause of high bills is increased usage (e.g. heating/cooling) 14 Health and safety cell phone Exposure to RF emissions from digital meters is much less than:
Televisions and remote controls Cellular telephones Bluetooth earpieces and USB Cordless telephones Laptop computers WiFi routers and base stations Wireless smoke detectors Microwave ovens Remote garage door openers Remote keyless automobile systems Motion detectors Hair dryers Wireless baby monitors
