Have you had trouble keeping track of smart metering projects? So have we, which is why we're glad to see the Smart Metering Projects Map run by the Energy Retail Association in the UK. The map essentially pinpoints smart metering projects across Europe, North America, Oceania and Asia on a zoom-able Google map. If you click on one of the flags, a few paragraphs pop up explaining the scope and purpose of the project. Distrigaz Sud, for instance, is installing 1.1 gas meters in southern Romania to offset gas network balancing concerns. The meters in the trial utilize snap-on Zigbee devices to permit communication. In Kyrgyzstan, a utility will test out pre-paid gas meters. (Pre-paid gas meters used to be a common fixture in the U.K. after World War II and are going to be trialed in parts of the U.S. for lower-income housing developments.) And my personal favorite, Bosnia Herzegovina's Elektroprivreda HZ HB Mostar is installing meters that communicate through power-line networking provided by Echelon. Echelon has also landed deals, and installed, power line-enabled meters and street lights in Italy, Norway and Texas. Italy already has 30 million smart meters, according to the map, which makes the country one of the more popular nations for smart meters. Elektroprivreda will initially only put in 200 meters but wants to boost the number to 200,000. There are no projects yet, according to the map, in South America or Africa, but there are proposals in the works for South Africa. At the risk of sounding redundant, smart metering will be one of the major issues and market for greentech in 2009 and beyond. Proponents say that smart meters and demand response programs can substantially curb greenhouse gases and energy consumption by more finely controlling the distribution and consumption of electricity, water and natural gas. Electrical grids, water utilities and gas pipelines, however, weren't designed with two-way communication and control in mind so bringing intelligence to these systems will require investments in networking, hardware and software.
