New open standard to enable faster roll-out of smart meters

Cambridge Consultants has launched the Universal Metering Interface (UMI), a low power, low cost, open communications standard that promises to speed up the roll-out of smart meters.

UMI enables manufacturers to start rolling out and installing smart-ready meters ahead of decisions about how they should communicate with the grid, appliances, or other devices. It is being offered by Cambridge Consultants as an open standard for the metering industry to help resolve the communications debate that is currently delaying the roll-out of smart meters. The Energy Saving Trust says smart meters can reduce consumer's carbon emissions by up to 10%. The European Commission's 2020 targets require an aggressive schedule for rolling out smart metering technology, but the deployment of these energy saving devices is currently delayed by an ongoing debate about which communication standards should be adopted. Alistair Morfey, technology director at Cambridge Consultants said: "Communications standards are vital to enable smart energy appliances to talk to the meter and the grid, but the RF interfaces which the Home Area Network (HAN) and Wide Area Network (WAN) will use have not yet been selected. "The UK government committed in May 2009 to install smart meters in all 26million homes by 2020, but even if roll-out begins in 2013, which is now the earliest realistic date, there will need to be at least 70,000 smart meter installations per week. Scale this up across Europe and it becomes clear that the debate about communications isn't going to be resolved in time, and that a solution to get things moving is needed. That's exactly what UMI offers." UMI is an ultra low power, low cost and highly defined board-to-board wired interface which will allow standard HAN (e.g. ZigBee or Wireless M-Bus) or WAN (e.g. GPRS) communications modules to be added to any metering product, either during production or in the field, when the communications standard has been agreed. Because the UMI communications module is entirely separate from the MID-approved (Measuring Instruments Directive) metrology components of the meter, there is no need to re-approve the meter when communications interfaces are changed. This drastically extends both the life of the meter and its marketability to different regions, and makes it future-proof for emerging standards and retrofits.
