We optimize how large batteries in the grid buy and sell energy. As the grid increasingly shifts to renewable energy from wind and solar, more and more large battery systems are needed to store that energy for times when there’s huge demand for energy but not enough supply. As a society, we have all the physical battery technology needed to do this, but the software technology that figures out when and how to optimally use the battery is still in its infancy. We’re developing self-optimizing, self-adapting systems that redefine how these large batteries are optimized so the grid can run on more clean energy.
