THE CHALLENGE

A small electric cooperative in Arkansas wanted to deploy two front-of-the-meter (FOM) storage systems, co-located with PV, to reduce their overall system peaks and increase the stability of the grid. Today's Power, a renewable energy company that developers, owns, and operates renewable assets was in search of a solution that would be able to accomplish that goal and also give the customer the ability to schedule the dispatch when they needed to. The customer specifically requested the ability to take full control and manually schedule the dispatch of their storage system on-demand. 

THE SOLUTION

Energy Toolbase's Acumen EMS™ controls software was integrated with two Sungrow energy storage systems, which utilize Samsung battery modules with a combined capacity of 9.6 megawatt-hours. The solution also included a license to the ETB Monitor platform, which provides a secure, web-based portal to view real-time performance, create alerts, and for the customer to schedule dispatch commands and override events.  The systems reduce yearly grid-level demand, minimize wholesale power costs, and increase grid stability for their customers were delivered on time and on budget.
