What Thermoflow does
Thermoflow Inc. is a privately held U.S. software company founded in 1987 and headquartered in Jacksonville, Florida, that develops a specialized suite of thermal engineering programs for designing, simulating, and economically evaluating power generation systems. The portfolio comprises nine modules anchored by dedicated expert systems for gas turbine combined-cycle and cogeneration plants (GT PRO, GT MASTER, PDE), conventional Rankine-cycle steam plants (STEAM PRO, STEAM MASTER), repowering (RE-MASTER), renewable and storage systems (NOVO PRO), a general-purpose network tool with 200+ components (THERMOFLEX), and a cost-estimation add-on (PEACE). Each dedicated expert program contains 3,500-4,000+ user-adjustable inputs and embedded thermodynamic and equipment-sizing knowledge built up over 200,000+ development hours, allowing users to generate complete plant designs, heat balances, and cost estimates in minutes rather than months. The suite integrates with Microsoft Excel via the ELINK add-in, enabling models to exchange inputs and outputs with in-house economic and correction-curve tools.
Thermoflow serves engineering, procurement, and construction firms (Bechtel, Fluor, Jacobs, Black & Veatch), power generation OEMs and utilities (Siemens Energy, GE Vernova, Mitsubishi Power, ABB, EDF, Duke Energy, Southern Company, Eskom, KEPCO), energy majors (Shell, BP, ExxonMobil), and research and academic institutions (EPRI, MIT) across 140+ countries. The company sells through a direct sales-led model staffed by regional managers and marketing consultants across Europe, the Americas, China, Southeast Asia, Brazil, Turkey, and ANZ, supported by trade show presence (ASME Turbo Expo, Carbon Capture Technology World Expo), recurring Users' Meetings, and structured training programs. Revenue is generated primarily through perpetual software licenses with multi-year contracts and modular add-ons (notably the PEACE cost-estimation module), with pricing kept confidential and negotiated enterprise by enterprise.

Thermoflow product offering
Product offeringCore offering
Thermoflow develops and licenses a suite of expert system software for the design, conceptual engineering, performance simulation, cost estimation, and economic analysis of power generation systems. The software covers gas turbine combined cycle, conventional steam, cogeneration, repowering, renewable energy (solar, wind, storage, hydrogen), and emerging thermal technologies such as carbon capture. The suite is sold via direct licenses, with the optional PEACE module providing bottom-up cost estimation and cash-flow analysis.
Product overview
Thermoflow offers a comprehensive suite of power plant design and simulation software comprising dedicated expert systems and a general-purpose program. The product portfolio includes: NOVO PRO (renewable energy systems), GT PRO/GT MASTER/PDE (gas turbine combined cycle and cogeneration plants), STEAM PRO/STEAM MASTER (conventional steam plants), RE-MASTER (repowering), THERMOFLEX (general-purpose thermal system modeling with over 200 components), and the PEACE module (preliminary engineering and cost estimation). GT PRO, GT MASTER, STEAM PRO, STEAM MASTER, and RE-MASTER are specialized expert systems with 3,500-4,000+ user-adjustable inputs each, designed to automate plant creation with intelligent built-in logic. THERMOFLEX serves as the general-purpose heat balance program, while PEACE adds engineering and cost estimation capabilities across all programs. Models can be exchanged between programs, and Excel integration is available via the ELINK add-in.

Thermoflow competitors and assessment
Company assessmentBroad incumbents
- ANSYS (Synopsys): ANSYS provides CFD, FEA, and system simulation (now part of Synopsys). It is used by power-generation engineers for fluid and thermal analysis that overlaps with Thermoflow's domain, though Thermoflow sells a more specialized heat-balance and plant-design product.
- MathWorks: MathWorks (MATLAB and Simulink) is widely used by power-systems engineers for plant modeling, control design, and optimization. It is a horizontal platform that competes for budget alongside Thermoflow's purpose-built plant-design expert systems.
- Siemens Simcenter: Siemens Simcenter is a broad multiphysics simulation portfolio sold into power and process industries. As a peer to Thermoflow it overlaps in thermal, structural, and system-level modeling for power-plant design, even though its scope is much wider than a single plant-design suite.
- Hexagon PPM: Hexagon's PPM division (CAESAR II, PV Elite, Smart 3D, HxGN SDx) provides plant-engineering and pressure-vessel design software to power and process customers. It overlaps with Thermoflow at the plant-level engineering and economics workflow.
Direct peers
- SoftInWay: SoftInWay's AxSTREAM platform is a dedicated turbomachinery design and simulation suite for turbines, compressors, and pumps. It competes with Thermoflow's GT PRO/STEAM PRO/THERMOFLEX in the same engineering workflow used by power and aerospace engineers.
- Aspen Technology (AspenTech): AspenTech (aspenONE, HYSYS, Aspen Plus) provides process and power-plant simulation software to engineers and operators. Like Thermoflow, it sells design, optimization, and economic-analysis tooling for thermal systems to the same EPC, utility, and OEM buyer base.
- GSE Solutions: GSE Solutions delivers power-plant simulation software and high-fidelity operator training simulators (including nuclear and conventional plants). It serves many of the same utility and EPC customers as Thermoflow and competes for power-systems modeling budgets.
- Concepts NREC: Concepts NREC provides AXIAL, CENTRIPAL, and other turbomachinery design and analysis tools. It is a niche specialist comparable to Thermoflow's GT PRO/PDE for engineers designing gas turbine, steam turbine, and compressor equipment.
- Honeywell UniSim: Honeywell UniSim offers process simulation and operator training for refineries, petrochemical and power plants. It overlaps directly with Thermoflow's combined-cycle and steam-plant modeling use cases and sells to many of the same utilities, EPCs, and OEMs.
Emerging players
- COMSOL: COMSOL Multiphysics is an emerging multiphysics platform used by engineers to build custom heat-transfer, fluid, and chemical-reaction models. It competes indirectly with Thermoflow when customers opt for a flexible modeling environment in place of a domain-specific plant-design suite.
