8 Technology Decision Considerations  Spectrum Availability No licensed spectrum available from FCC Unlicensed spectrum used heavily in Houston Metro 25 kHz bandwidth licensed spectrum not sufficient for throughput needs  Performance Requirements Throughput speeds greater than 100 kbps required 99.9 % Reliability  Environmental Requirements Ambient Temperature range: -30 to +60 degrees Celsius Relative Humidity: 95% non-condensing Relative  Technical Requirements Ethernet Port Remotely managed  Product Availability Product had to be currently available Product had to be previously deployed 8

9 Evaluation Criteria  Evaluated based on: Technical capabilities of proposed solution Scalability of proposed network Overall, per-site and performance cost basis Longevity and market stability of proposing company Security compliance and capability 9

10 Technology Wireless Cellular Hardline Most Geographic Coverage (typically) No additional infrastructure for backhaul Broadband coverage Rapid deployment Engineer accordingly to requirements Build for the future (higher bandwidth) Potential for synergies within field network Rapid deployment (once in place) Proven technology Able to configure/size accordingly BPL\PLC Utilize existing infrastructure The “Broadband” promise Large “theoretical” geographic coverage Benefits Most deployments rely on multiple technologies to achieve a full coverage cost effective solutions High variable expense cost for data usage Reliance on cellular infrastructure Rapidly changing environment and technologies Infrastructure cost Achieving coverage, i.e., geographies, meter density in certain areas Permitting High fixed expense cost Difficult to manage individual circuits Reliance on carrier infrastructure Long Installation timeframes Frequency interference High price point Limited success in the field trials Challenges Communication Components Considered 10

11 AMS Communication Network Components  Hybrid Backhaul Solution AMS Backhaul (Radio/Wireless) PRIMARY Communication Path  This portion of the communication network connects the “take-out” points to/from the cell relay devices in the field  Bandwidth – 128 Kbps (minimum requirement)  Utilizes a new “purpose-built” WiMAX infrastructure (GE MDS Mercury 3650 Radio System)  Operates in the lower 3.65 GHz Band  WiMax 802.16d Standard  Redundant configuration  Ethernet Interface, 10/100BaseT, RJ-45  Point to Multi-Point Design, Access Point to Remotes  3 Sectors per Tower AMS Backhaul (Cellular) SECONDARY Communications Path  This portion of the communication network connects the cell relays to the data center via the AT&T cellular network  Bandwidth is adequate  Meter Communications Smart meters operate in a Mesh Network The Cell Relay is the Master Meter of the Mesh Network 11

15 Agenda  CenterPoint Energy Smart Grid Communication Network Overview Technology Decision Solution Architecture  Deployment and Operation Lessons Learned Deployment Considerations Keys to Success  Question and Answer 15

16 Deployment Considerations….. The communications network deployment must be closely coordinated with the meter deployment. Cell Relay Site Selection Take Out Point Site Selection “Network communications in place 3 months ahead of meter deployment” Design ratio of 400:1 Meter to Cell Relay/ collector Meter Deployment Map 16

17 Deployment Considerations….. Be prepared to utilize creative design and installation solutions to meet aggressive timelines. Cell relay site selection process In the absence of a permanent TOP A temporary TOP was paced on top of a 150’ “Condor” crane at the Dunlavy substation to test signal strength at proposed cell relay sites near Memorial Park. 17

18 Deployment Considerations….. Complete the design up front, integrate components into an overall architecture, analyze/test all materials, complete construction standards, and prove installation procedures via testing/training 18 Proto-type: Test fit, constructability, parts list. Final Construction Standard: DSM approved. Install procedure developed. Installed Cell Relay Site 123 18

19 Deployment Considerations….. Manage materials and multiple service suppliers closely and establish strong field coordination along with detailed construction and performance acceptance / testing processes. Major equipment and long lead items such as cell relays, radios, network electronics, towers and buildings need to be specified, bid and ordered. 19

20 Deployment Considerations….. Analyze, select, implement network management tools early as they are used for both construction and operations. 20

21 Deployment Considerations….. Communication solutions developed ahead of time to address the network coverage needs for remote and low meter density areas.  The last 1% of meter coverage requirement  Tools on the bag – communication solutions RFLAN range extenders - meter collector mesh network extensions 900MHz systems – provide extended coverage areas WiMax Repeaters – provide additional WiMax coverage  Solution and combination of solutions are selected for application based on network availability, environmental and meter density WiMax RFLAN RFLAN Mesh RFLAN Range Extenders Example 21

22 Deployment Considerations….. Leverage a common communications infrastructure. The IG Network is built on the AMS Communications Infrastructure. AMSIG Fiber backhaul Microwave backhaul WiMAX (Primary) GSM (back-up) Satellite (back-up) 22

23 Deployment Considerations….. Consolidate equipment in field. Communications equipment is integrated with distribution electronics into a common enclosure. Communications Equipment 23

24 Some Keys to our success thus far… 1. Apply a proven network architecture method to ensure coverage of network design issues. 2. Develop solid business and technical requirements and ensure agreements with all stakeholders. 3. Strong Governance processes. A strong PMO utilizing proven governance methodology is essential to overall success. 4. Integration and close alignment of all project areas and support functions. Procurement, IT, distribution standards, systems development, communications infrastructure, meter deployment, suppliers, etc., must all work together in a coordinated fashion and not in silos. 5. Material contracts. Managing material contracts closely and maintaining sufficient material inventories is critical. 6. Design & Installation Standards & Procedures. Efficient, safe and cost efficient designs and installation standards need to be in place to meet schedules, minimize costs and provide for on- going required maintenance. 7. Solid Deployment Strategy. The meter deployment strategy and schedule must be in synch with the communications infrastructure build schedule to meet aggressive timelines and performance expectations. 8. Exception Management. Even small percentages of exceptions – like access or design issues can be disruptive if not handled expeditiously. 9. Operational Strategy. Soon after deployment begins and the first device goes into production, a plan must be in place to operate and maintain the equipment and systems. 24
