  • This slide shows Oncor’s AMS deployment profile: Currently, we’re one of the largest deployment in the U.S., installing up to 3.2 million meters by 2012 and serving about 7 million people in our service area. Eventually, we’ll ramp up to about 800,000 to 900,000 meters a year until all meters are installed.
  • Let’s talk about “Smart Texas.” What is it? And where does Smart Grid and AMS fit in? Here you can look at the definition of each.
  • What are the components of Smart Grid? Smart Grid includes substations and advanced meters—which are the heart of AMS. It also includes SCADA—you may have heard of that. We have data in the field and we need to get that back to the office. We do that through backhaul communications such as satellite, radio frequency, and cellular. We have many IT applications and distribution automation. All this is to support Oncor and the market. Smart Grid leads to better system integrity and reliability.
  • How did we get here? Back in 2005, we started our automated meter (AMR) initiative. We put in 600,000 automated meters. Then, the Texas Legislature passed a law that basically said, “We want advanced meters.” In May 2007, the PUC issued a rule defining requirements for those meters. Our AMR meters were not compliant with the new requirements, so we cancelled the program and started AMS, with the PUC’s approval.
  • The Oncor advanced meters meet all PUC technical and functional requirements.
  • So what are the components of AMS? The program provides funding for in-home devices for qualified customers. If you look at the IT infrastructure, essentially all Oncor IT applications have been touched, so modifications are required there, including new and revised business processes. We now have a common portal that all REPs, consumers, and ERCOT will use. There’s a telecommunications component to get the meter data to and from the office. It’s critical to make sure consumers understand the benefits these meters provide and how they can leverage this information, so we have a customer education program that includes before and after installation, as well as the MEC. And then, of course, there’s the meter installation itself.
  • Why are we doing AMS? It allows us to know more about how the system is performing. Consumers are able to know and observe more about their energy consumption. We know when and where to spend money on improvements. It provides new opportunities for rates and pricing plans. All of this leads to a better system design.
  • Let’s go ahead and look at some of the details. (Let them read and perhaps talk about a few bullets based on audience interests.) We now have nearly 3,000 reads per month per meter. The safety of our employees has increased because we no longer have to send them out to read the meters or perform disconnects and reconnects. We can now quickly reconnect those with prepaid pricing plans. Customer load control will be opt-in (e.g., ERCOT-directed load shedding). Since deployment began, we’ve prevented more than 2 million truck rolls, saving approximately $16-20 million in people, truck, and fuel costs.
  • With AMS, we know when a outage occurs and we know when it’s restored. It narrows down where the problems are. We can read meters on demand. HAN devices allow you to read energy consumption and estimate what your bill will be. Everyone in Texas will go to the same site for account maintenance.
  • Some of our key milestones: The program started in 2009 and the plan is to finish by 2012. If you look, there are some interim regulatory commitments, plus numbers to hit.
  • Let’s talk briefly about how AMS works. We read the meter, collect the data, and make sure it’s accurate. Then we send the meter data to where it’s needed—either to billing or to the market.
  • Let’s discuss how the meter data gets from the meter to the market: Again, we read the meter and that data flows inside your house and to the RF mesh, which is Landis+Gyr’s Gridstream network. L+G is our primary AMS vendor, supplying our meters and the related network equipment. The second box shows the data flow through the mesh—it might be through multiple meters or a series of routers. Eventually it goes to a collector at a substation and to the Head End, the software application that controls the meter and provides a way for us to get the data back to the home office. Once it’s at the back office, we validate and process the data through some of the applications shown here. Then, we transmit the data to the parties that need it—in this case, ERCOT, REPs, and consumers.
  • This is a more detailed breakdown of what’s happening: An important note on the HAN. There are no production HAN devices available today. Our validation team is testing several pre-production models to ensure they work with our system. We expect to see some models in production this year. ZigBee is a low-frequency radio in the meter—similar to Bluetooth—and is the standard for in-home area network devices.
  • The router acts like a cell phone tower—sending the signal where it needs to be relayed. As many as 10,000 to 15,000 meters could route signals to a single collector. From there, the data is sent to the backhaul network and the back office, as shown here. Again, Head End is the vendor software that talks to and controls the meter.
  • This is just another picture of the RF mesh: It’s a 900 MHz proprietary network that uses meters or routers to get the signal to the collector. The collectors are normally in substations so we have a power supply and can get the data to the back office, as shown here. In addition to the RF mesh: The intent is to incorporate a power line carrier (PLC) network for rural areas. This is dependent on vendors developing a PLC-compliant advanced meter.
  • MDMS does the validating and produces billing-quality data. LCIS provides the premise and billing data. AMS ODS provides our long-term storage and provides data for reporting. AMS Maximo manages our assets. Our internal Web portal is used for reporting and analysis.
  • Once the meter data is valid and bill quality, we store it a data repository that can be accessed through the customer portal or Web services, which allows the REPs or ERCOT to access large amounts of data and register HAN devices.
  • This slide shows some of our partners for the AMS implementation.
  • If you look at the deployment, you’ll see that we actually have metropolitan and non-metropolitan areas. If you have a question about your deployment, you can go to, put in your ESI ID, and see when your meter will be installed.
  • Here we can see what’s deployed outside of the D/FW area.
  • If you have questions about AMS, there’s quite a bit of information on our website. We’re also on Twitter!

    6. 6. AMS Background “…put information and control into the hands of the consumer,Oncor’s AMS initiative has evolved as a with integrated technologies that enable individuals to obtain timelyresult of PUC regulations: information on energy use, manage their own consumption patterns and reduce costs.” – PUC Oncor launches its automated meter reading initiative and begins 2005 replacing traditional meters with automated meters. The Public Utilities Commission of Texas (PUC) adopts its advanced meter 2007 ruling, including specific technical and functional requirements for meters. Oncor’s automated meters are not compliant with the PUC’s new regulations and as a result, Oncor revises its automated meter reading initiative to become an advanced metering system that is PUC-compliant. The PUC approves Oncor’s AMS program filing, including a surcharge to 2008 recover implementation costs.Oncor Electric Delivery CONFIDENTIAL – FOR INTERNAL USE ONLY 6
