A fully automated systemwhere embedded large pools of sensors in the existing electricity grid systems for monitoring and controlling it by making use of modern information technology is what is known as Smart Grid. By deriving and processing new information from these data in real time it can be made more applicable. Energy consumption prediction, which is a significant part of smart grid, may be difficult to handle with huge energy usage data in the grid. This is because the redundancy from feature selection cannot be avoided. Our aim is to predict the commercial energy consumption by a building based on its previous consumption history. First, we apply a correlation based feature selection method in order to filter out the most relevant attributes. Out of the resulting dataset so formed, for the purpose of dimensionality reduction we use a Kernel Principle Component Analysis methodology. What we obtain will be a set of principal components which will be our new dataset. To predict the energy usage, we use a Support Vector Regression method that uses kernel technique that determines a suitable point as the predicted value. Finally, we evaluate the performance of the predictor based on different evaluators to understand the efficiency of the technique.
