The company provides installation, maintenance, and fabrication services for natural gas distribution systems, trenchless underground infrastructure (horizontal directional drilling), distributed power generation, and data center infrastructure across approximately 25 U.S. states and Canada. Its customer base comprises investor-owned and municipal natural gas distribution utilities, industrial energy users, and data communications sector clients, with strategic alliances held since the early 2000s with the largest natural gas providers in Utah and Illinois.
The company holds ASME S, ASME U, and National Board R Stamp certifications for fabrication of pressure-bearing components, and operates a fleet of more than 13,000 assets deployed in field operations. Service lines include natural gas distribution construction, horizontal directional drilling, emergency response and storm restoration, NBC-class traffic control, and in-house fabrication supporting infrastructure deployment. In 2025, the company opened a 70,000-square-foot fabrication facility in Greenwood, Mississippi, expanding its manufacturing footprint into the Southeast U.S. utility corridor.
The business model is project- and contract-based, generating revenue through long-term master service agreements with IOUs and municipal utilities, multi-decade strategic alliances with major gas providers, and project-based work for industrial and data communications customers. The company is supported by more than 9,600 employees through its parent organization, enabling round-the-clock field deployment and emergency mobilization across geographically dispersed service territories.

National competitors and assessment
Company assessmentDirect peers
- Quanta Services: Largest pure-play U.S. utility infrastructure services company, providing electric and natural gas transmission and distribution construction, HDD, and emergency storm restoration. Highly comparable across NPL's core service lines, with deeper electric infrastructure exposure and broader scale.
- MasTec: Diversified infrastructure construction firm serving utilities, oil and gas pipelines, and communications, including HDD and pipeline distribution work through subsidiaries such as IEA Construction. Directly comparable business model with multi-utility exposure and national footprint.
- IEA Construction: Subsidiary of MasTec providing utility construction services including natural gas distribution, HDD, and pipeline installation. Highly comparable on service mix, though not independently traded and operates as part of a larger parent.
- Primoris Services Corporation: Infrastructure construction company serving utilities, energy, and civil markets, with pipeline, distribution, and storm restoration capabilities. Direct peer across natural gas distribution construction, fabrication-adjacent services, and emergency response.
- MYR Group: Specialty contractor focused on electric transmission and distribution construction, with commercial and industrial electrical work. Comparable as a national utility infrastructure construction peer, though more electric-skewed than NPL's gas-heavy mix.
- Miller Pipeline: Utility pipeline construction company specializing in natural gas distribution and pipeline integrity services. Closely comparable core service offering, though smaller and more regionally focused than NPL's national footprint.
- Snelson Companies: Pipeline construction and infrastructure services firm with natural gas distribution and HDD trenchless installation capabilities. Direct peer in gas distribution construction, though smaller in scale than NPL's Centuri-affiliated platform.
Broad incumbents
- EMCOR Group: Large mechanical and electrical construction services provider serving commercial, industrial, and utility markets. Adjacent peer with infrastructure construction exposure but with broader commercial/industrial mechanical focus rather than NPL's utility pipeline specialty.
- NEUCO: Utility construction services company and sibling brand within Centuri Group. Provides natural gas distribution and related construction services with overlapping capabilities to NPL, though serving different customer relationships and geographies.
- Riggs Distler & Company: Utility construction and infrastructure services company, operating as a sibling brand under Centuri Group alongside NPL. Overlaps in gas, electric, and HDD services but covers the Northeast and Mid-Atlantic regions and serves investor-owned utilities from a different geographic base.
