Energy monitoring is one of the important applications arising from research in Internet of Things (IoT). Smart meters allow us to obtain periodic updates of energy consumption data that can be analyzed to provide important insights into energy usage. However, design limitations in smart meters only allow the monitoring of the aggregated consumption data instead of real-time consumption data.
Increasing cost and demand of energy has led many organizations to find smart ways for monitoring, controlling and saving energy. A smart Energy Management System (EMS) can contribute towards cutting the costs while still meeting energy demand. The emerging technologies of Internet of Things (IoT) and Big Data can be utilized to better manage energy consumption in residential, commercial, and industrial sectors.
