Cal MicroTurbine

What Cal MicroTurbine does

Cal MicroTurbine is a California-based (Costa Mesa) distributor and integrator of Capstone oil-free microturbine power systems, founded in 2016 and operating with 11-50 employees. Its core offering is fuel-flexible on-site generation technology ranging from 65 kW to multi-megawatt configurations, including named products such as the C1000S high-pressure natural gas generator, the C800S and C800S Signature Series microturbines, and trailer-mounted mobile EV charging units. Underlying technology centers on proprietary oil-free architecture that enables quiet operation, ultra-low maintenance, and the ability to combust natural gas, biogas, hydrogen blends, renewable natural gas, and waste gas fuels. Combined cooling, heating, and power (CCHP) configurations achieve up to 95% total efficiency through thermal capture, with modular deployments scalable without expanding site footprint.

The company monetizes across three revenue streams: hardware sales of microturbine products, the Energy-as-a-Service (EaaS) / rental model offering capex-light deployment, and recurring parts sales and service agreements tied to the installed fleet. Its customer base spans oil & gas operators, data centers and other critical power users, agricultural biogas facilities, real estate developments, and EV charging infrastructure — with documented enterprise deployments such as PSECU (data center UPS), Costa Group (agriculture), Biokurasix Handa (biogas in Japan), and an unnamed compression plant achieving 100% energy independence.

Cal MicroTurbine was acquired by Capstone Green Energy Holdings, Inc. (NASDAQ: CGEH, now Capstone Energy+) in Q2 FY2026 (completed by quarter-end September 30, 2025; announced November 13, 2025) as part of Capstone's strategy to strengthen its distributor network and drive Microturbine Products and EaaS revenue. Post-acquisition, the entity operates within the parent company's distribution ecosystem, contributing to the parent's reported 33% year-over-year quarterly revenue growth and seventh consecutive quarter of positive Adjusted EBITDA. Leadership consists of Ryan Brown as CEO and managing partner.
