Client Challenge

High energy bills from a combination of consumption and demand charges are a concern for our clients at Southern Illinois University. There are multiple buildings with high power requirements, and demand becomes a large part of their bill when a lot of power is used over a short period of time.


Our solution is a sustainable, wireless communication Battery Energy Storage System that is a superior alternative to diesel-powered generators. A solar PV was integrated with a Battery Energy Storage System to ensure application of solar PV at its highest efficiency. The power generated can respond to the unpredictable nature of peak demand.



TROES was the best choice to build a hybrid Battery Energy Storage System that worked together with on-grid solar. It will provide power during peak hours while charging or support the load at night. This will be the source of power when there is a blackout.
