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
While Phase 1 covers about 15 percent of CenterPoint Energy’s service area, some of the improvements will benefit consumers in the entire system.
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

Consumer Benefits of Intelligent GridView 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 Mayor’s 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 Energy’s deployment of intelligent grid technology in the Houston area is the Task Force’s strongest recommendation.”
It has been estimated that full intelligent grid functionality could improve reliability by up to 30%.16

Challenges
● First-of-a-kind deployment● Performance at operational scale● Knowledge transfer
Subject matter expertise
● Volume of data● Business transformation● Process change activities
Need to consistently engage employees
● Consumer education and myth-busting

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

Components of Cyber Security Strategy
Prevention Reduce risks and vulnerabilities Intervene and stop attempted occurrences Mitigate effects
Detection Identify anomalous behavior Detect malicious code and other events Gather digital evidence
Response Address short-term direct effects of incident (public safety et al)
Recovery Restore normal operation & Address issues
CenterPoint Energy’s 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 nation’s 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

Conclusion
“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.”

Smart meters are accurate and secure
CenterPoint Energy takes the accuracy of its meters very seriously, which is why we have in place a rigorous testing and quality assurance process: 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
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
