Why Standards?Standards ensure reliabilityFirst and foremost, meter readings have to be reliable. In order to gain confidence inthe benefits of smart meters, consumers must understand that these devices providevaluable tools that enable them to more effectively manage their consumption.Proper management will result in lower bills. At the same time, utilities need toknow that each kilowatt is accounted for. To date, there are many standards that areused to measure the accuracy of the metrology portion of the meter; however, assmart meters become integral parts of an ecosystem that gathers remote telemetricinformation on network conditions such as voltage, power factor and line anomalies,many of these standards are still emerging. Since many meters also have the abilityto report sensed outage conditions, basic metrics for establishing a common set ofcriteria for reporting of these still remains undefined.“Whether you are dealing with a traditional meter or asmart meter, you need to be sure that what it says isaccurate.”— Bartjan Kaptein, Manager,DNV KEMA Calibration & Metering Lab“For a multi-vendor solution, open (international)standards are preferable—it’s the only way to ensureinteroperability.”— Maurice Adriaensen, DNV KEMA12Smart meters and standardsSmart meter rollout34Why standards?The right stepswww.dnvkema.com4
Why Standards?Standards ensure effective communicationwhile lowering riskA meter is only ‘smart’ if it can communicate effectively with other equipment.Because multi-vendor solutions are inevitable, clear communication criteria needto be defined in advance, specifically how meters, data concentrators, and centralsystems will work together. In Italy and Sweden, proprietary standards are usedfor communication between meters and central computer systems. However, asincreasing layers of technology are added, a network of meters built on proprietarystandards alone poses risks for effective, system-wide communication. As newtechnologies and vendors come into the market, there is no way to guarantee thatthey will communicate with older technologies or each other, making their integrationinto the grid a longer, more expensive process.Components of the Smart Grid“An energy company that’s got hundreds of thousands– or even millions – of meters clearly doesn’t want toreplace the whole lot.”— Maurice Adriaensen, DNV KEMA12Smart meters and standardsSmart meter rollout3 Why standards?4 The right stepswww.dnvkema.com5
