A smart grid uses analogue or digital information and communications technology to gather and act on information, such as information about the behaviors of suppliers and consumers, in an automated fashion to improve the efficiency, reliability, economics, and sustainability of the production and distribution of electricity.
The information flows in the electricity cables, or with wireless commun
If you follow the energy sector, you’d be aware that the word “smart” gets bandied about quite a lot. Smart meters, smart cities and smart grids are all the rage. New South Wales based retailer and distributor EnergyAustralia has picked up a neat $100M as the winning bidder for the "Smart Grid, Smart City" project.
Logica has followed up its October 2009 survey the smart grid industry in Australia with new survey that shows significant progress in the last 12 months but identifies massive challenges for the energy sector in developing the more intimate customer relationships and developing the new business models that smart grids will engender.
While there’s a vigorous debate in Australia about the rising cost of electricity, and the introduction of smart meters, the global smart meter industry continues to gain steam, with meter manufacturers shipping nearly five million meters in the first quarter of this year.

Also, the mains voltage here is 220V but it comes weak mostly, 180 and lower and even down to 100!
