Constant change in the industry due to continuous technological innovation makes new challenges for Smart grid in this market appear. Except traditional voice, the smart grid will incorporate new networking technology, including sensors and controls that make it possible to monitor electricity use in real time and make automatic changes that reduce energy waste. The smart grid could make the supply of electricity more efficient and reliable, and it could help reduce greenhouse-gas emissions by promoting renewable technologies and reducing overall power consumption.
The smart grid needs equally smart communications to deliver some benefits. The communications network must be as dynamic, secure and reliable as the power grid as the two become increasingly interdependent.
