Ever want to ride a rocket ship? Ever want to do hard work that will make a REAL difference in the world? Do you want to solve some of the most difficult problems with a team of exceptional players at a company that does not believe in impossible?


Powin is a leading producer of a utility scale modular battery energy storage system (complete with a patented, advanced, cloud-based monitoring/control system). That means we build power plants out of batteries that put coal and gas generators out of business and enable sustainable viability for renewable energy sources like solar and wind.

Powin is, and will continue to be, one of a handful of companies that will provide the equipment necessary to make this happen. Powin has distinct competitive advantages: cost-effectiveness; reliability; scalability; ease of deployment; and operational sophistication. Every day we work to ensure that we maintain these competitive advantages and our position as a global leader in providing turnkey, battery energy storage solutions for utility-scale, commercial and industrial, and microgrid applications.
