DELTA STAR, INC.
LYNCHBURG, VA

Delta Star, Inc., originally founded as Delta-Star Electric in Chicago in 1908, specializes in manufacturing equipment crucial for the electrical generation, transmission, and distribution sector. Over its extensive history, it evolved significantly after being acquired by H.K. Porter Company in 1950, eventually becoming a standalone entity through an Employee Stock Ownership Plan in 1988. The company is renowned for its construction of transformers capable of managing voltages up to 315,000 volts and maintaining a Basic Insulation Level (BIL) rating up to 900. Its product offerings extend across utility applications, such as power, distribution, generator step-up units, UAT grounding units, voltage regulators, and autotransformers, as well as industrial uses including secondary load centers and hazardous location transformers. In addition to stationary products, Delta Star is a leader in building mobile transformers, which serve critical roles during emergencies or in remote installations. These mobile solutions are versatile with capacities reaching up to 100 MVA and can handle various voltage requirements on both high and low sides. Quality control is paramount at Delta Star; the company designs and manufactures its critical components in-house to ensure each product meets specific customer needs, establishing robust trust among global utilities. This self-reliance extends to creating their transformer tanks, switches, and tap-changing equipment using high-quality materials and processes—such as double-shielded MIG welding for weld seams—to guarantee exceptional performance. As an only North American manufacturer providing a full suite of power products like auto transformers, voltage regulators, and mobile substations, Delta Star upholds its legacy through innovation in control cabinet design and nitrogen systems. The company's commitment to quality is further evidenced by its use of a rigorous paint system developed to withstand extreme environmental testing. Based in Lynchburg, Virginia, with an office number 3550 Mayflower Drive and additional headquarters at 1001 Corporate Parkway West Suite 400 in Belmont, California, Delta Star remains committed to technological advancement and customer satisfaction. Incorporated in Florida as For-Profit status on September 2, 2014, it continues to thrive under leadership from CEO Jason Greene and CFO James Mott, among others.
