Overview
Capstone Green Energy Holdings, Inc., which officially rebranded as Capstone Energy+, Inc. in April 2026, is a key developer and provider of clean, behind-the-meter, microturbine-based distributed energy solutions. Headquartered in Van Nuys, California, the company addresses the global energy trilemma: the simultaneous market demand for power generation systems that deliver operational resiliency, cost affordability, and environmental sustainability. Capstone develops and manufactures oil-free, friction-free microturbines that operate on a highly flexible array of gaseous fuels, including pipeline natural gas, liquid petroleum gas (LPG), biogases, flare gases, and hydrogen-blended fuels without requiring hardware modifications. The company generates revenue across three primary business segments: Product and Accessories, Parts and Service, and Rentals and Energy-as-a-Service (EaaS). Geographically, Capstone's global footprint spans 89 countries with more than 10,800 units shipped, with core markets in North America and expanding channels across Europe, Latin America, and Asia. Capstone’s customer base comprises commercial and industrial entities where power quality and constant operational uptime are mission-critical. Key end markets include high-density artificial intelligence (AI) data centers, hospitals, hospitality resorts, agricultural processors, municipal wastewater plants, and remote oil and gas extraction sites. Customers prioritize Capstone over traditional reciprocating internal combustion generators because of its patented air-bearing technology, which eliminates routine maintenance downtime, operates quietly, produces ultra-low emissions, and minimizes the total cost of ownership.
