What nootereriksen does

NOOTER/ERIKSEN is an employee-owned thermal design and heat transfer specialist, headquartered in St. Louis, Missouri, with a European headquarters in Milan, Italy, and operating as a subsidiary of CIC Group Inc. Founded in 1987 through the merger of ERIKSEN Engineering (Tulsa, Oklahoma) and the NOOTER Cogen Group (St. Louis, Missouri), the company has grown into the world's leading supplier of Heat Recovery Steam Generators (HRSGs), with more than 1,000 HRSGs installed across 55 countries. Its customer base spans electric utilities, independent power producers, oil & gas operators (enhanced oil recovery), waste-to-energy and biomass facility developers, concentrated solar power developers, and industrial process steam users, with major disclosed relationships including Calpine, Siemens, Mitsubishi, FP&L, Toshiba, Black & Veatch, and ENI.

The company's core technology centers on custom-designed, natural-circulation HRSGs featuring horizontal exhaust flow and vertical tube design, supported by multiple proprietary innovations including external heat exchangers for cold-end corrosion prevention, multi-drum designs for high ramp-rate cycling, supercritical evaporators with horizontal exhaust gas paths, high-efficiency stainless-steel feedwater heaters, and a patent-pending Low Low Temperature Economizer (LLTE) using thermoplastic tubes for sub-dew-point operation. Beyond HRSGs, the product portfolio now includes fired boilers (up to 500 t/h, 565°C, 150 barg), waste-to-energy and biomass grate combustion boilers, simple cycle exhaust treatment systems with SCR/CO catalyst, enhanced oil recovery once-through steam generators, and molten salt receivers for CSP tower plants. The company is qualified under ASME, CE/PED, EN12952, Canadian TSSA, Japanese METI, Australian, and Russian GOST codes, and was the first US HRSG supplier to obtain ISO 9001 certification in 1993.

NOOTER/ERIKSEN generates revenue through custom equipment manufacturing contracts with utilities and power producers, recurring aftermarket services (component fabrication, engineering inspections, replacement parts, design enhancements) across its installed base, and technology licensing and royalty arrangements with five regional manufacturing partners (Calgary, Istanbul, Chennai, Monterrey, Hangzhou) plus the N/E-CCT joint venture covering the EU, Middle East, and North Africa. Go-to-market is enterprise field sales targeting utilities, IPPs, EPCs, and GT OEMs, supported by 19 remote sales representatives across the US, Italy, the UK, South Korea, Thailand, the UAE, and China. Pricing is project-specific and not publicly disclosed. Distribution combines direct sales, licensed regional manufacturing, and a joint venture, with sister companies Wyatt and NOOTER providing construction capabilities and CIC Group providing financial backing for turnkey EPC delivery.

Scale indicators11 records

Recent moves9 records

Expansion highlights6 records

Direct peers

• Vogt Power International: Vogt Power (part of Babcock Power Inc.) designs and manufactures HRSGs for combined-cycle and simple-cycle plants globally. Closest direct competitor to N/E in custom-engineered HRSG supply to utility-scale gas turbine projects.
• Optimus Industries: Optimus Industries fabricates custom HRSGs, heat exchangers, and industrial boilers. Comparable in product scope (HRSGs, industrial boilers) and customer base to N/E, with similar custom-engineering model.

Broad incumbents

• Babcock & Wilcox (B&W): B&W is a large diversified boiler and steam-generation incumbent serving utility, industrial, and environmental markets. Overlaps with N/E in fired boilers and steam generation but is much broader in scope and includes a captive HRSG supply chain via Vogt Power.
• Mitsubishi Heavy Industries (Power Systems): Mitsubishi manufactures heavy-duty gas turbines and has captive HRSG capabilities. Both a customer (43 HRSGs from N/E) and a competitor in the HRSG market via OEM-aligned supply.
• Siemens Energy: Siemens Energy supplies gas turbines and competes in adjacent thermal equipment markets. Both a major customer (58 HRSGs) and a competitor with potential captive HRSG capabilities.
• Cleaver-Brooks: Cleaver-Brooks manufactures industrial boilers, heat exchangers, and related equipment. Overlaps with N/E's fired boiler and industrial steam generation product lines, though Cleaver-Brooks skews more toward packaged firetube/watertube commercial-industrial boilers.
• Wood Group (formerly Foster Wheeler): Wood Group's heritage Foster Wheeler business designs and supplies utility and industrial boilers, including CFB and waste-to-energy units. Comparable in scale and scope on the fired boiler and WTE/biomass side of N/E's portfolio.

Emerging players

• Thermax Limited: Indian-headquartered Thermax designs and manufactures boilers, heaters, and energy solutions. Comparable in fired boiler and waste-heat boiler categories, though with stronger domestic Indian positioning and more packaged-boiler orientation than custom HRSGs.

Regional players

• SolarReserve (Crescent Dunes peer set): SolarReserve is a CSP project developer rather than a direct HRSG competitor, but is a strategic partner (Crescent Dunes) and benchmark for the molten-salt receiver market where N/E competes. Useful as a channel/customer-adjacent comparable.
• Doosan Enerbility (formerly Doosan Heavy Industries): South Korean power plant OEM that manufactures boilers, steam generators, and turbines. Regional competitor with comparable HRSG and utility boiler capabilities in the Asian market where N/E has licensee partnerships.
