  • Anyone seen one of these?
  • A bit about the Texas marketDeregulatedOncor and, also Centerpoint are T&D only companies – in the yellowCompetitive market for generation and retail electric serviceThe TDSPs are the FEDEX for electric transport, the enablers for the marketDo not directly own the customers but often take care of their concerns
  • Flexible, modular design97 interfaces
  • Flexibility of designWhere it makes sense, keep the bulk loads, otherwise run it through the bus.
  • Now we have a common portal for all TDSPsCommon interfaces for REPs, customers, ERCOT, and third partiesCurrently Oncor, Centerpoint are members, AEP joins next week, TNMP soon based on AMS filingCosts are determined annually & readjusted by meter count
  • Flexible, modular design97 interfaces
  • Gives the customers and REPs information about usageAllows for more informed energy usageData is available on a “one day” later, i.e. last nights data would appear todayNow we provide data on an FTP site to REPs
  • Consumer education is a key focus for Oncor’s AMS initiative. It is critical to make sure that consumers understand the benefits these meters provide and how to leverage the information they are gaining with the new system. Our communications team has devised a comprehensive plan with multiple touch points using a variety of marketing tactics to effectively reach consumers prior and during the deployment of their new advanced meters. Oncor will conduct telephone polling of consumers in our service area before and after the advanced meter deployment to measure awareness and perceptions about the new advanced meters and the ongoing consumer education campaign. Consumers will be notified in advance and the day of their meter install via door hangers in English and Spanish. These door hangers outline key benefits they will receive and will include a letter from the PUC Chairman, Barry T. Smitherman. Oncor is executing an aggressive media plan with print, theater, bill board and online advertising. We are also continuing our tours of the Mobile Experience Center that were started last year by taking the exhibit to the communities we serve for a combination of meter deployment events and local fairs and festivals. And finally, we will continue to generate consistent media coverage in our metering districts as we deploy that will also help build awareness.
  • The advanced meters are deployed by metering districts in a sequence that will enable Oncor to eliminate manual meter readings in an entire meter reading district. AMS will be deployed in metro areas and non-metro areas concurrently for operating efficiency and so that both urban and rural areas will essentially have equal access to advanced meters. A deployment plan approved by the PUC is available on our Web site at There will be a monthly surcharge of $2.19 per residential consumer to be paid once a month over the next 11 years. Three important areas were considered by the PUC when determining this surcharge: estimated capital costs, estimated operating and maintenance costs and estimated savings to be realized over the surcharge period. The $2.21 a month is one of the lowest in the nation and a minimal investment compared to the savings we can expect from reducing our demand. Consumers will be able to completely off-set this cost with the easy replacement of a 100 watt light bult for an Energy Star CFL light bulb.
