What’s up with the HomePlug Powerline Alliance‘s dream of connecting the smart grid through household wiring? The 70-member group is working to bring HomePlug — a powerline networking standard with some 215 devices certified and 50 million chips deployed — into interoperability with a host of smart grid networking technologies, including ZigBee and the IEEE 1901 powerline networking standard. On Tuesday, the alliance named three chipset vendors – Atheros Communications, Gigle Networks and SPiDCOM  — participating in an interoperability “plugfest” this week in Tours, France. HomePlug is mainly used in broadband, video and home automation systems, but its Green PHY is aimed at smart grid applications, and is being used to connect homes to smart meters in Australia and Germany.
