This document discusses using Hadoop for smart meter data analytics. Smart meters track energy usage and send data to utility servers. Analyzing large volumes of smart meter data presents challenges due to data growth rates. Hadoop can help by reducing data loads and improving query performance due to its scalability. The document outlines how Hadoop can enable demand response analysis, time of use tariff analysis, and load profile analysis. It also provides diagrams of a Hadoop cluster and data flow for smart meter data analytics.
