An energy management system using big data analytics can help lower energy prices for commercial microgrids. Sensors can be installed on lights and ATMs to monitor energy consumption data. By analyzing this data, issues like lights running during the day or AC units left on after hours can be identified and corrective actions taken to reduce consumption. Predictive analytics can also determine which lights may need replacing or use the most electricity. This solution helped one company save 25-30% on energy costs and lower overhead by 9.48% in just one year.
