Smart Grid : An opportunity for FPGAs in Home Appliance space?

According to this EEtimes article, the Association of Home Appliance Manufacturers (AHAM) took the opportunity of being at the United Nations Climate Change Conference in Copenhagen to release a very well written 25 pages document titled “The Home Appliance Industry’s Principles & Requirements for Achieving a Widely Accepted Smart Grid“. In this document, the AHAM – based on its unique perspective to the Smart Grid Vision – is intended to provide three essential requirements for the Smart Grid’s interaction with consumers in order for the Smart Grid to be successful. Among those three requirements, the second one is the most interesting from a technological (embedded systems) perspective :

Communication Standards must be open, flexible, secure, and limited in number

This requirements then splits in four requirements : open, flexible, secure and limited in number.

From a FPGA perspective, flexible sounds very familiar because its embedded in the name of the technology itself : Field-Programmable. But is this flexibility may solve problems and help the development of Smart Grid enabled homes ? According to the authors,

Smart Grid enabled homes will have varying levels of sophistication, depending on the type of appliances, devices, and networks that are installed. There are many configurations, combinations, and options for energy management inside the home. Some possibilities could include a simple email notice for a manual demand response by the consumer, a smart meter directly communicating with a specific appliance to ask it to turn on and off, or a meter communicating with a Programmable Communicating Thermostat allowing for temperature adjustment.”

From now to the moment that every appliance is going to talk the same language – even with such standardization, that is limited to the US only – one can think that this is going to be long and costly. This process has been started since a long time on industrial side (with many types of protocols) and there is still no single communication standard. Altera and Xilinx are actually taking advantage of this massive willingness to connect but protocol-segmented environment. Their programmable chip solutions enables them to sell a platform on which industrial equipment manufacturers can then use to build their own platform which is going to be finally customized with a regional/market-specific set of IP blocks. This approach enables flexibility while also reducing costs and time to market.

Is the same idea is going to happen in Home Appliance space ? As we all know, this high-volume market is very focused on costs. Not considering smart grid, a chip to chip price analysis would probably give only small chances to FPGAs. But considering that :

– according to a recent Whirlpool survey, 84% of consumers choose energy – not water or time – as most important when it comes to home appliance efficiency, and that

– according to Electric Power Research Institute, the implementation of Smart Grid technologies could reduce electricity use by more than 4 percent by 2030 providing a mean savings of $20.4 billion for businesses and consumers,

… there may have an opportunity there for FPGA chip manufacturers. Among the most important ones, Altera is already there.
