What Frank Lill & Son, Inc. does

Frank Lill & Son, Inc., founded in 1922 and headquartered in Victor, New York, is a privately held specialty mechanical contractor serving the power generation industry across North America. The firm operates as a single-source prime contractor across EPC/design-build, general contracting, construction management, and prime mechanical scopes, complemented by outage and aftermarket maintenance, in-house fabrication, emissions compliance, controls upgrades, and commissioning services. Core technical capabilities include HRSG and OTSG installation across turbine sizes from under 7MW to over 200MW, advanced multi-process welding (SMAW, GTAW, Flux Core, Orbital, MIG) on a wide range of alloys, and BIM-enabled construction planning for logistically constrained sites. Backed by a self-perform direct-hire workforce and a 40,000 sq. ft. fabrication facility completed in 2013 with 35-ton bridge crane capacity, the company has delivered reference projects including the 650MW Kleen Energy Center combined cycle plant, the 400MW York Energy Center simple cycle plant (with continued minority ownership), the 100MW Waterbury Generating Station, the 150MW UGI Hunlock Creek repower, and recurring central plant work for Cornell, Penn State, University of Virginia, and Iowa State.

The company serves utilities, independent power producers, universities, government and military installations, and industrial clients in petrochemical, manufacturing, food and beverage, and aerospace. Revenue derives from project-based contracting across multi-year EPC and design-build engagements, fixed-price and negotiated general contracting, construction management fees, and recurring outage/maintenance service work. Go-to-market is exclusively enterprise-direct sales through competitive bid, RFP response, and relationship-driven repeat business with no public consumer marketing. The firm operates regional branches in Philadelphia (Mid-Atlantic) and Tennessee to serve Northeast and Southeast markets, and historically maintains long-tenure service relationships (e.g., 30-year emergency maintenance at Cornell; work at Eastman Kodak since 1987; ongoing TVA outage work at Cumberland).

• Primoris Services Corporation: Primoris' Power, Industrial, and Engineering segments deliver utility-scale power construction (turbine, HRSG, BOP, emissions), heavy civil, and outage services to utilities and IPPs across North America. Direct competitor for the EPC, mechanical, and outage scopes Frank Lill & Son pursues.
• Sargent & Lundy: Sargent & Lundy is an engineering and EPC firm focused almost exclusively on power and energy projects, including fossil, nuclear, and transmission. Direct overlap with FLS on combined-cycle, simple-cycle, and repowering EPC/design-build for utilities and IPPs.
• Zachry Group: Zachry Group's Power Division is one of the largest heavy industrial mechanical contractors in North America, executing EPC, direct-hire craft, and outage work on utility power plants (gas, coal, nuclear). FLS and Zachry frequently compete for the same prime mechanical and outage scopes for utility and IPP clients.
• Bernhard Capital Partners / Bernhard MCC: Bernhard is a privately held energy and infrastructure services firm delivering mechanical, electrical, and energy-efficiency EPC for utility, institutional, and industrial clients. Comparable to FLS as a mid-sized, multi-trade EPC focused on power and central-plant projects with strong outage/maintenance practice.
• Burns & McDonnell: Burns & McDonnell is a 100% employee-owned EPC firm with deep power generation practice covering simple-cycle, combined-cycle, and emissions retrofits. FLS is frequently subcontracted to Burns & McDonnell on design-build power projects, and the overlap in turbine, HRSG, and boiler scope makes them a directly comparable EPC competitor.

Broad incumbents

• AECOM: AECOM's Energy practice delivers engineering, EPC, and construction services across fossil, nuclear, transmission, and renewables. Significantly larger than FLS, but a comparable counterpart on utility-scale EPC, repowering, and outage work for the same North American utility and IPP clients.
