MARY HELEN PARKEY

Mary Helen Parkey specializes in the manufacture and supply of critical electrical infrastructure components for federal energy and defense systems, with deep expertise in high-voltage power transmission equipment. The contractor delivers specialized products including power transformers, switchgear, circuit breakers, disconnect switches, instrument transformers, lightning arresters, and high-voltage bushings—components essential for substation reliability and grid resilience. Their technical focus centers on precision-manufactured electrical systems that meet stringent federal performance and safety standards, particularly where original equipment manufacturer (OEM) compatibility is required and competition is not feasible due to technical exclusivity or urgent operational needs. The contractor’s ability to source and supply mission-critical, non-standard components under tight timelines demonstrates a unique capacity to support infrastructure modernization and emergency restoration efforts. They maintain consistent engagement with the Department of Energy and the Department of Defense, providing components for power distribution networks, switchyards, and transmission systems that support national energy security and military base operations. Work for the Southwestern Power Administration and Western regional entities further underscores their role in maintaining federal hydropower and grid infrastructure. Their solutions are often deployed in remote or high-voltage environments where reliability and OEM alignment are non-negotiable. The contractor’s industry focus lies in electrical equipment manufacturing under NAICS 335311 (power and specialty transformers), 335313 (switchgear), and 335999 (miscellaneous electrical components), with additional experience in industrial control systems and power transmission equipment. They serve as a niche supplier for hard-to-source, high-reliability components used in utility and defense-grade applications. As a Women-Owned Small Business certified under the SBA’s 8(a) and WOSB programs, Mary Helen Parkey operates from Middlesboro, Kentucky, positioning itself as a trusted small business partner in federal energy and defense supply chains. Their certifications and technical specialization enable them to compete for set-aside contracts requiring verified small business status and domain-specific manufacturing capability.
