A grid (electrical) that is capable of being electronically controlled and that grid is used for connecting transmission, power generation, distribution (of electricity) as well as consumers using communication and or along with information technologies is called Smart Grid. Information flow that is Bi-directional in nature between the one that provide utility and the one that consumes electricity is one the key feature characteristic of the smart grid. This interaction that is two way in nature permits real time generation of electricity orin real-real--time period based on the demands of the consumer and requirement requests for power. The result of which is, privacy of the client becomes a vital importance and concern, when the usage data that is related to energy is collected with adoption as well as the deployment of smart grid technologies. For the protection of such sensitive data and information (related to consumer), it makes the use of mechanism that are used for privacy protection very much imperative or important for the protection the of smart grid user’s privacy. This paper proposes an analysis related to the privacy mechanisms and solutions of the smart grid that are recently proposed and intern identifying their weaknesses as well as strengths in terms of their efficiency, complexity of implementation, simplicity and robustness.
