FlexEnergy Solutions

What FlexEnergy Solutions does

FlexEnergy Solutions designs and manufactures small-scale gas turbine and microturbine power generation systems under the Flex Turbine brand, sold as the Original Equipment Manufacturer (OEM) or leased to industrial and commercial customers. The product portfolio spans 250 kW (GT250S), 333 kW (GT333S), and 2 MW (GT2000S) units, which may be deployed individually or combined into modular FlexGrid microgrids to scale site power from 150 kW up to 10 MW. The technology features wide fuel tolerance (gas from 350 to 2,500 Btu/scf, sour gas with H2S up to 6,500 ppmv, up to 70% CO2), ultra-low emissions of ≤10 ppm NOx and CO, 99.5%+ uptime, and a single annual 8-hour maintenance interval. The company has maintained CARB certification for the GT333S for ten consecutive years, an uncommon regulatory milestone.

The company targets three primary verticals: oil & gas operators (Permian, Delaware, Bakken, Appalachian basins, and historically the Western Canadian Sedimentary Basin), manufacturing, and large commercial/industrial customers, with secondary exposure to data centers/data mining, institutions (hospitals, universities), and wastewater/landfill biogas applications. Revenue comes from three streams: hardware sales (turbine units and skid/trailer-mounted packages), recurring leasing arrangements (flat monthly or kWh-based, with service and maintenance bundled), and managed service operations supported by 24/7 remote monitoring and locally-based service teams. The technology originated from FlexEnergy's 2011 acquisition of Ingersoll Rand's small gas turbine business; Flex Leasing Power and Service and FlexEnergy, Inc. merged in 2018 to form the current entity, headquartered in Centennial, CO. The company is privately held, received equity investment from Intervale Capital in December 2014, and in May 2025 signed a Purchase and Sale Agreement to divest its Canadian operations to focus on U.S. growth. In October 2024, FlexEnergy signed an exclusive deployment agreement with Enterprise Group for Flex Turbine solutions.

Revenue model

1. Gas Turbine Leasing: FlexEnergy leases and services the most resilient, clean gas turbines available for off-grid or grid parallel applications. Lease packages are available at remote sites with highest uptime power with skidded or trailered Flex Turbine options. Leases are structured to right-size project power capacity, helping producers reduce operating costs while meeting capital and operating expense needs. Options include flat monthly lease or kWh energy generated lease. Base lease pricing includes all service and maintenance for leased equipment.
2. Gas Turbine Sales / Equipment: Sale of Flex Turbine power solutions (GT250S, GT333S, GT2000S) as Original Equipment Manufacturer. Multiple Flex Turbine units sold to customers for self-generation and CHP applications, with engineering support provided for electrical and gas system design.
3. Service Operations & Remote Monitoring: 24/7 monitoring, data collection, and service included in lease packages. Locally-based service teams provide critical power site support. Additional fees are added for referral or commission arrangements.

Core offering

FlexEnergy Solutions designs, manufactures, and services the Flex Turbine line of natural gas microturbine and small gas turbine power generators (250 kW, 333 kW, and 2 MW units) for industrial and commercial customers. The company offers these systems through direct sale or multi-year lease packages that include skid-mounted/trailer-mounted deployment, remote monitoring, and 24/7 service operations. Multiple units can be combined into a FlexGrid microgrid to scale power from 150 kW up to 10 MW per site for oil and gas, manufacturing, large commercial/industrial, data center, institutional, and wastewater applications.

Product overview

FlexEnergy Solutions offers a portfolio of gas turbine power solutions centered on its Flex Turbine brand of microturbines and small gas turbines, available in 250 kW (GT250S), 333 kW (GT333S), and 2 MW (GT2000S) configurations. The core Flex Turbine products are modular units that can be deployed individually or combined into a FlexGrid microgrid for scalable power needs ranging from 150 kW to 10 MW. The company provides these systems through sale or flexible leasing arrangements (skid-mounted and trailer-mounted packages) that include comprehensive service operations with 24/7 remote monitoring. Beyond standalone turbine sales, the portfolio includes cogeneration/CHP solutions that capture waste heat for enhanced efficiency, off-grid power systems for remote oil and gas operations, and grid-connect options for parallel operation with utility power. Service offerings encompass factory-trained maintenance teams positioned in key energy-producing regions, backed by real-time performance monitoring capabilities. The product line targets industrial and commercial institutions requiring reliable, clean power in sectors including oil and gas, data centers, manufacturing, and institutional facilities.

Broad incumbents

• Generac: Generac is a leading manufacturer of power generation equipment including natural gas generators and energy storage systems for residential, commercial, and industrial customers. It overlaps with FlexEnergy in commercial/industrial CHP and behind-the-meter applications, increasingly bundling gas generation with storage and solar.
• Siemens Energy: Siemens Energy is a global gas turbine OEM whose small industrial turbine technology underpins FlexEnergy's GT2000S. Siemens competes in the broader industrial and utility-scale gas turbine market and could choose to extend its own small gas turbine offering more directly into FlexEnergy's niche.
• Wärtsilä: Wärtsilä is a global manufacturer of flexible gas engines and balancing capacity plants for grid and industrial applications. Its gas engine portfolio competes with FlexEnergy's CHP and distributed generation offering for large industrial and utility-scale customers seeking low-emission gas-based power.
• Caterpillar (Electric Power): Caterpillar's Electric Power division offers a broad portfolio of gas and diesel generator sets, including gas gensets used in oilfield and industrial applications. While it does not specialize in the microturbine niche, it competes for distributed power RFPs at the upper end of FlexEnergy's range and offers a much larger service network.
• Cummins: Cummins produces natural gas reciprocating generators and power solutions used across data centers, hospitals, and industrial sites. It competes with FlexEnergy in CHP and behind-the-meter applications, leveraging a far larger distribution, service, and balance-sheet footprint.

Direct peers

• Enchanted Rock: Enchanted Rock delivers natural gas-powered backup and continuous power-as-a-service to commercial, industrial, and institutional customers, similar to FlexEnergy's leasing model. It targets behind-the-meter resiliency and competes for the same large-commercial customer base, particularly in Texas.
• Capstone Green Energy: Capstone is the closest direct competitor — a California-based OEM of natural gas microturbines in the 30 kW to 1 MW range serving oil & gas, CHP, and distributed power customers. It competes head-to-head with FlexEnergy's GT250S and GT333S for similar customers, applications, and CARB-certified low-emission positioning.
• Aggreko: Aggreko is the world's largest temporary and mobile power rental provider, offering gas, diesel, and increasingly cleaner-fuel generator solutions to oil & gas and industrial customers. It competes directly with FlexEnergy's leasing model for remote oilfield and industrial temporary power deployments.

Emerging players

• Mainspring Energy: Mainspring Energy develops linear generator technology for distributed power that runs on multiple fuels including natural gas and biogas. It targets commercial, industrial, and utility customers seeking low-emission dispatchable generation — directly intersecting with FlexEnergy's CHP and distributed generation use cases.

Regional players

• Enerflex: Enerflex (formed via the Exterran combination) provides power generation, gas processing, and energy infrastructure solutions to oil & gas and industrial customers across the Americas. It competes with FlexEnergy in oilfield power, particularly across the Western Canadian Sedimentary Basin — the very market FlexEnergy divested in 2025.
