What Sentry Electrical Group does
Sentry Electrical Group, Inc. is a private, founder-owned electrical construction contractor headquartered in Lawrenceville, Georgia, that has specialized in renewable energy infrastructure since its 2006 founding by Norm Cowden. The company delivers turnkey electric power construction services — wind turbine tower wiring, medium and high voltage collection systems (underground and overhead), solar photovoltaic EPC, battery energy storage system (BESS) integration, and ongoing operations and maintenance — to utility companies, electric cooperatives, municipalities, renewable energy developers, and Fortune 100 industrial clients across 30 U.S. states. The company reports operational scale of 300+ completed wind projects, 16,500–20,000+ turbines wired since 2008, and 300+ miles of underground collection systems built, and is recognized by Energy Acuity as a top-10 EPC contractor in the renewable energy sector.
The company's service portfolio is organized around four divisions — Wind (including tower wiring and repower), Solar (including medium voltage and battery storage), Collection Systems, and Operations & Maintenance — each staffed by dedicated crews with separate project management. Underlying technical capabilities include medium/high voltage cable installation, pad mount transformer and switchgear installation, fiber optics splicing, and electrical testing (Meger, VLF, Partial Discharge), supported by a proprietary quality assurance program and a 'Family First. Safety Always.' safety culture with OSHA-compliant training led by a dedicated Safety Division Director. Procurement and compliance integrations span Procore, Oracle Textura, Ariba, SmartBid, ISNetworld, Avetta, Veriforce, and ComplyWorks, positioning the company to bid as a sub-tier or balance-of-plant partner on large utility-scale renewable projects.
Sentry generates revenue through project-based construction contracts with custom, quote-based pricing and multi-year contract cadences, sold via direct enterprise field sales and online quote requests. Customers include NextEra Energy, Vestas, Siemens Gamesa, GE, Mortenson, Blattner Energy, Fagen, Wanzek, RES, Acciona, WFEC, PowerSouth, IEA, CEG Engineers, and VeloSolar.

Sentry Electrical Group competitors and assessment
Company assessmentDirect peers
- Mortenson Construction: Mortenson is a top U.S. renewable energy EPC contractor delivering wind, solar, and BESS projects. Sentry is explicitly listed as one of Mortenson's subcontractors on a project page, making them a direct, named peer in the same specialty electrical scope and same customer base.
- Fagen Inc. Fagen is a leading U.S. wind EPC contractor and named Sentry customer. Both firms compete for wind tower wiring and collection-system work on the same developer-led projects.
- MasTec (incl. Wanzek): MasTec, through its Wanzek brand, is one of the largest U.S. utility-scale wind EPC contractors. Wanzek is listed as a Sentry customer and direct rival for wind electrical construction scopes.
- McCarthy Building Companies: McCarthy's Renewable Energy & Storage group builds utility-scale solar, wind, and BESS projects. It competes with Sentry for the same collection-system and BoP electrical scopes on renewable prime contracts.
- RES (Renewable Energy Systems): RES is a global renewable energy developer and EPC contractor delivering wind, solar, and storage projects. As a named Sentry customer and direct competitor on wind/solar collection and BoP scopes, RES is a clear direct peer.
- Blattner Energy (Quanta Services): Blattner Energy is one of the largest U.S. utility-scale wind EPC contractors and is named as a Sentry customer. Both companies compete for the same wind electrical-balance-of-plant work on the same prime-contractor projects.
Broad incumbents
- Burns & McDonnell: Burns & McDonnell is a 100% employee-owned engineering and construction firm delivering T&D, substation, and renewable generation construction. It is a broader incumbent competing for utility-side and renewable electrical scopes that overlap with Sentry's portfolio.
- Quanta Services: Quanta owns Blattner Energy and is the largest specialty utility infrastructure contractor in North America, providing T&D, substation, and renewable construction services. It is a broader incumbent that competes for the same scopes from a much larger balance sheet.
- Pike Electric / Pike Construction Services: Pike is a large specialty electrical contractor delivering T&D, substation, and renewable interconnection work for utilities. It competes with Sentry's utility / collection-system business and benefits from similar utility-side tailwinds.
Others
- Vestas-American Wind Technology: Vestas is a leading wind turbine OEM and a named Sentry customer. While not a direct EPC competitor, it is a key ecosystem participant whose U.S. installation pipeline determines a significant share of Sentry's revenue.
