Machine learning energy consumption forecasting system

Technology #cu13111

By using initial energy usage data from a given manufacturing facility, as well as seasonal patterns and weather predictions, the machine learning forecasting system can predict the facility’s future electricity consumption. The system ties into electric vehicle (EV) recharging infrastructure associated with the facility, optimizing EV recharging loads and schedules based on usage and weather information. By comparing actual usage with usage predictions, the forecasting system continues to learn from the manufacturing facility it monitors, becoming more accurate and saving additional money and energy the longer the forecasting system is used.

A continuously learning energy forecasting system is scalable and saves costs over time

The feedback loop built into the machine learning forecasting system scores the accuracy of its own predictions, minimizing errors and inefficiencies over time. The system thus gets better at helping manufacturing facilities and companies avoid peak consumption penalties. It allows companies to more efficiently use their capital assets, extending the lifetime of those assets and reducing expeditures. The system is scalable to hundreds of EVs associated with the manufacturing facility, and has been demonstrated in a package delivery facility that processes tens of thousands of packages per day.
