Texas Market Independent generator Competitive market Sells at wholesale Not regulated for price Monopoly utility Transmission services Distribution services Measurement services Delivery services are REGULATED REPs pay for delivery Prohibited from generating, owning, or selling electricity Competitive market Sells at retail NOT REGULATED for price, rate structure, or service offerings May sell other services to consumers Bills & collects payments for total monthly electric bill, REGULATED for certain consumer protections
Texas Market (cont.) The consumer may own a HAN and related devices to monitor and manage energy usage, or may obtain them via service or other business arrangement from REPs or 3 rd parties No PUC requirements will be established for in premise functions, beyond the meter to HAN function Usage data capture within the HAN directly from the meter or the SMT portal are the customers, and they have responsibility for such data, including how they secure it, with whom and how they may share it Much like WiFi based HANs already in homes today REPs may utilize any communication they choose to implement demand response or other energy service functions The utility AMS system is one avenue for the defined set of functions Consumer broadband or other communication networks may also be utilized

Oncor HAN Testing Program (cont.) Worked interactively w/ami vendor and HAN equipment vendors to resolve errors found during testing Differences in interpretation of SEP v1.0 Specifications Chasing bugs HAN device firmware Meter firmware AMI headend software SMT software
Testing goal: Make sure the AMI headend and meter firmware can successfully respond to all interpretations of the SEP v1.0 specification Ultimate goal: Through interaction w/the ZigBee Alliance, work to drive out the variability in the SEP 1.0 specification Any HAN device with the ZigBee Smart Energy seal can be successfully provisioned and operate with any compatible Smart meter in Texas, California, or the country

ZigFesTx Oncor and CenterPoint are sponsoring a series of ZigBee test events in Texas Two testing stages Preproduction equipment testing against the standard ZigBee SEP 1.0 test harness Hardware w/production security certificates testing end to end through the SMT portal and L+G and Itron AMI headends and meters Multiple meters and multiple devices in a simulated production environment
ZigFesTx Test teams met in Houston the last week of April to write the test scripts First event was held in Ft. Worth last week 10 vendors in attendance XX devices tested Several additional events planned for this summer and fall fll
HAN Device Deployment Oncor is deploying small numbers of HAN devices w/employees for field tests Oncor will be deploying 500 IHDs throughout its deployed service territory in early July to help publicize the Smart Grid RFP issued for a Texas (ERCOT) wide low income program to issue IHDs to qualified residents to allow them to take advantage of available smart grid information
The Texas Market Several Retail Electric Providers are planning production deployments of HAN devices this summer.
Final Thoughts: Smart Energy Profile v1.0 HAN devices work in production environments Th T k i ih 1 illi The Texas market is open with over 1 million smart meters in sockets
