Smart Grid
A smart grid delivers electricity from suppliers to consumers using two-way digital technology to control appliances at consumers' homes to save energy, reduce cost and increase reliability and transparency. Such a modernized electricity network is being promoted by many governments as a way of addressing energy independence, global warming and emergency resilience issues. Smart meters may be part of a smart grid, but alone do not constitute a smart grid.
A smart grid includes an intelligent monitoring system that keeps track of all electricity flowing in the system. It also incorporates the use of superconductive transmission lines for less power loss, as well as the capability of integrating alternative sources of electricity such as solar and wind. When power is least expensive a smart grid could turn on selected home appliances such as washing machines or factory processes that can run at arbitrary hours. At peak times it could turn off selected appliances to reduce demand.
Gnrgy is working towards the home/enterprise smart grid future enabling any entity (individual, business, government, and corporation) to manage all of its energy and other resources individually and/or in collaboration with the utility provider. Gnrgy expects that energy management networks will be a standard overlay of the wireless networks that today exist as local wireless internet networks, acting as private smart grids. A resources private network that will be either self managed or shared management between the entity and the utility company/management company.
Utility companies have a strong need for such a solution as the Smart Grid revolution will not evolve without the ability to reach to the end device at home or office. Currently, utilities focus on smart metering as the major issue of Smart Grid but already started focusing their attention to the end user management network, including HAN/BAN. This is a critical part for the success of other key features of Smart Grid such as DMS (Demand Response), EMS (Energy Management Systems), price plan adaptation and carbon reduction. Moreover, utilities will have to manage huge amounts of private smart grids and the real time data from each and therefore will have to integrate new middleware which will be capable and oriented to handle large amounts of real-time information in order to make DMS and peak shaving decisions.
