Capstone manufactures microturbines used for on-site electricity generation by commercial and industrial customers. These small, gas-fired power generators operate similarly to jet engines and range from 65 kW to multi-megawatt configurations. Capstone's systems feature fuel flexibility, running on natural gas, hydrogen blends, and biogas. The company utilizes proprietary air bearing technology to eliminate oil and lubricants, reducing maintenance needs and improving uptime. Capstone targets sectors including data centers, hospitals, and oil and gas operations where reliability is critical. Capstone generates revenue through three primary streams: equipment sales, recurring maintenance agreements, and Energy as a Service (EaaS) offerings like rentals and power purchase agreements. Capstone sells products through a global distributor network and a growing direct sales presence. Capstone's growth strategy focuses on addressing power demand from AI data centers and utility grid constraints through integrated equipment packages and high-voltage DC outputs. With over 10,800 units shipped to 89 countries, Capstone prioritizes combined heat and power (CHP) applications that capture waste heat to increase total system efficiency.
