Discover Why We Are Passionate About Transforming the Edge of the Grid

Our passion for transforming the edge of the grid stems from our belief that the future of energy lies in agile, distributed solutions. By turning everyday resources—like agricultural pumps and smart thermostats—into powerful grid assets, we unlock new possibilities for utilities and their customers alike.

We combine cutting-edge software, real-time analytics, and intuitive controls to deliver practical results today while paving the way for tomorrow’s energy demands. Every device at the grid edge contributes to a more sustainable, reliable, and cost-effective power system—one that benefits utilities, communities, and the environment at large.
