What AUI does

AUI Partners is a Fort Worth, Texas-based private partnership operating as a full-service commercial and renewable energy construction contractor since 1983. The firm delivers projects through multiple procurement models — Construction Manager-at-Risk (CMAR), Design-Build, Competitive Sealed Proposal, Negotiated, and Hard Bid — serving municipal and government clients (school districts, cities, counties) as well as private enterprise customers across retail, healthcare, education, industrial, and non-profit sectors. AUI self-performs civil, structural, and electrical work and operates a formal QA/QC system with dedicated quality personnel on every project.

The company's renewable energy division, launched in 2006, provides turn-key EPC services for solar PV, battery energy storage systems (BESS), and wind projects, and has cumulatively installed over 4,000 MW across the United States. Disclosed experience includes 100+ PV projects, 25+ wind projects, and a multi-gigawatt utility-scale pipeline scheduled for 2025–2027 with developers including NextEra, Lydian, X-Elio, and Nexus. Separate BESS and Distributed Generation (DG) Solutions business units extend the renewable product set beyond utility-scale solar.

Revenue is generated on a project-bid basis under multi-year contracts, with pricing determined per project scope and delivery method; no standard pricing is publicly disclosed. Customer relationships are direct (no channel intermediaries), with marketing driven primarily by portfolio reputation, Solar Power World Top Solar Contractor recognition spanning nine consecutive years, and industry association memberships. AUI operates from Fort Worth, TX (headquarters) and Fargo, ND (secondary office), with active project delivery spanning all major US regions.

Direct peers

• MYR Group: MYR Group's subsidiaries (The L.E. Myers Co., Huen Electric) provide electrical construction including substations and BESS interconnect work for utility-scale renewable projects. Overlaps with AUI's self-perform electrical scope and renewable developer clients.
• Mortenson Construction: Mortenson is one of the largest US EPC contractors for utility-scale wind, solar, and BESS projects. Direct comparison to AUI's renewable EPC services: same delivery model, same developer customers (including NextEra), and a comparable self-perform civil/structural/electrical approach.
• McCarthy Building Companies: McCarthy is a national EPC combining commercial/municipal construction with a renewable energy division covering solar PV and BESS. Directly comparable to AUI's two-pronged commercial + renewable model and CMAR/Design-Build delivery on municipal work.
• Primoris Services Corporation: Primoris operates a Utility-Scale Solar, BESS, and Power Delivery segment with full EPC and self-perform civil/electrical capabilities. Directly comparable to AUI's three-mode renewable offering and renewable developer customer base.
• Wanzek Construction: Wanzek is a MasTec-owned utility-scale wind, solar, and BESS EPC contractor serving the same developer customer base as AUI (including past relationships with NextEra). Closest direct match to AUI's renewable BoP EPC delivery and self-perform model.
• Swinerton Incorporated: Swinerton combines a national commercial/municipal construction practice with a dedicated Renewables group executing utility-scale solar and BESS. Closely mirrors AUI's commercial + renewable dual focus and CMAR delivery.

Broad incumbents

• Burns & McDonnell: Burns & McDonnell provides full-service EPCM (engineering, procurement, construction management) for utility-scale renewable projects. Comparable delivery model on the engineering and owner-side CM work; broader portfolio across power, transmission, and federal.
• Fluor Corporation: Fluor is a global EPC major with a dedicated Energy Solutions business covering utility-scale solar, BESS, and wind. Overlaps AUI's renewable EPC scope, but Fluor also operates across LNG, mining, and government services at vastly larger scale.
• Quanta Services: Quanta is the largest pure-play utility infrastructure contractor in North America, with growing utility-scale renewable energy and BESS exposure. Overlaps with AUI's renewable BoP work but operates at much broader scale across transmission and distribution.
• MasTec (IEA subsidiary): MasTec, through Infrastructure & Energy Alternatives (IEA), is a Tier-1 utility-scale renewable EPC with wind, solar, and BESS capabilities. Overlap with AUI is direct on the renewables side; MasTec is significantly larger, giving it better cost-of-capital and balance sheet capacity to win 100MW+ projects.
