Powin Energy

What Powin Energy does

Powin Energy was a Portland, Oregon-based integrator of utility-scale battery energy storage systems (BESS), founded in 2013 and operating until its June 2025 Chapter 11 filing. The company's core offering centered on containerized lithium-ion BESS products, culminating in the Pod Max — a 6.26 MWh per-unit system introduced in May 2025 — designed for grid-scale applications including renewable integration, peak shaving, and grid stability. Powin acquired Spain-based EKS Energy in September 2022 and GPTech in December 2022 to vertically integrate power conversion and grid optimization capabilities into its hardware stack. The company sold primarily through enterprise field sales to utilities, independent power producers, and project developers, securing reference deployments with BHE Renewables (Berkshire Hathaway Energy), DTE Energy, Galp in Portugal, and an undisclosed titanium producer in West Virginia. Geographic reach spanned more than 10 countries with over 2 GWh deployed across North America, Europe, and Brazil.

Powin's go-to-market was project-based and hardware-led, with revenue driven by custom quote-based contracts for utility-scale installations rather than recurring software or service revenue (though a services entity was formed during bankruptcy to maintain installed systems). The company raised $135 million in growth equity from GIC in July 2022 and secured a $200 million revolving credit facility from KKR in October 2024, but was unable to convert capital into a sustainable operating model. Powin held approximately $300 million in unsecured debt and approximately 250 jobs at the time of its Chapter 11 filing, citing high interest rates, import tariffs, and federal policy uncertainty as proximate causes. In August 2025, FlexGen Power Systems acquired Powin's intellectual property, hardware, software, IT systems, and spare parts inventory out of bankruptcy for approximately $36 million, with Powin ceasing to operate as an independent entity.
