Southeast Power Corporation

What Southeast Power Corporation does

Southeast Power Corporation (SEPCO) is a privately held, Florida-incorporated electrical construction contractor founded in 1959 as Mamba Engineering Company and headquartered at 1805 Hammock Road, Titusville, FL. The company serves electric power and utility customers with a full suite of construction and maintenance services: power transmission line construction and maintenance from 46kV to 500kV (including wood pole, tubular steel, concrete, and lattice tower lines), electric distribution systems below 46kV, turnkey substation construction up to 500kV, fiber optic and telecommunications system installation (including OPGW and ADSS), drilled pier and caisson foundations through its Precision Foundations division, storm restoration and emergency response, environmental construction (right-of-way clearing, silt fence, laydown yards), and electric vehicle charging station construction. Field capabilities include barehand energized line work up to 500kV and operations in restricted-access terrain using helicopters and barges. The company runs a 4-year Department of Labor-registered Journeyman Lineman Apprenticeship Program with 640 hours of classroom instruction delivered via Lake Sumter State Community College and 8,000 hours of on-the-job training, and is an active OSHA Electrical Transmission & Distribution Partnership member.

The business model is project-based, one-time, milestone-driven construction contracting rather than recurring subscription or licensing revenue. Southeast Power bids on and is awarded contracts by utility companies, supported by regional offices in Spartanburg, SC (Carolina Division, established 2002, exclusive AFL Telecommunications representative for fiber optic systems nationwide) and Bastrop, TX (Texas Division, established 2010, with a notable $104 million 110-mile 345kV CREZ transmission line project). Go-to-market is direct enterprise sales to utility clients, with project acquisition through competitive bidding and long-standing client relationships (e.g., Florida Power & Light, Orlando Utilities Commission). The company operates an in-house fleet maintained through a partnership with Caterpillar, with most fleet equipment under three years old, and maintains full internal fleet maintenance and transport capabilities.

Ownership history: Southeast Power became a wholly-owned subsidiary of Power Corporation of America in 2013 when PCA was formed by The Goldfield Corporation (NYSE American), and was subsequently repositioned in 2020 as a wholly-owned subsidiary of GridTek Utility Services, where it sits today. Headcount is reported at 251-500 employees, and no revenue, backlog, or financial figures are publicly disclosed in the available source material.
