Headquartered in Greater Portland, Oregon, Powin is a global provider of scalable battery energy storage systems. Powin's business model, which spans from battery cell procurement through project operation, allows the company to control the full integration of its systems, closely manage assembly costs, control quality, and have certainty around supply chain. To date, Powin has installed or delivered over 4 GW of battery storage projects, and coupled with its contracted sales pipeline.

The Powin Stack™ and StackOS™ battery energy storage platform is a vertically integrated and purpose-built solution for the demands of utility-scale, commercial and industrial, and microgrid applications. Powin's Stack hardware also features a modular architecture and streamlined installation process allowing for efficient scaling from MWh to GWh scale. Behind Powin's products there is almost three decades of supply chain management expertise and extensive battery management software (BMS) development proficiency.

Fully-integrated Powin battery energy storage systems are priced per kWh.

Powin's Performance Guarantee is included with each full deployment and allows flexibility on applications and usage for the life of the system.

Beyond Powin's Performance Guarantee, Powin's Long-Term Service Agreement offering can provide more predictable project performance through the availability guarantee, capacity maintenance, and O&M services.

Powin Stack hardware and StackOS™ software are built to work better together as an all-in-one storage platform built from end-to-end. Powin's hardware products include both batteries (Stacks) and smart enclosures, or modular Centipede Stacks. Powin hardware is coupled with software (StackOS) featuring both on-site and remote access.

The modularity of Powin's Stack eases installation, simplifies maintenance, reduces downtime, and lowers operation costs.

Typically serving large C&I and Utility-Scale applications in the 20MWh+ range, Powin systems can scale easily to multiple MW systems for indoor and outdoor environments. Stack architecture also allows for energy capacity management made simple by augmenting fully integrated Stacks to DC bus.

Powin provides large-scale energy storage systems for utilities, IPPs and project developers.
