Orangeburg High-Voltage Cable Manufacturing Plant

The Okonite Company announced a new approximately 552,000-square-foot high-voltage cable manufacturing plant on its existing property at 2276 Rowesville Road in Orangeburg, Orangeburg County, South Carolina. The $400 million project is expected to create 105 permanent jobs. Construction is expected to begin in Q4 2026 and take roughly two to three years, so the expected opening (approximately 2029) is uncertain. This is a new plant on existing company property and is not merged with any unrelated earlier expansion.

This project also meets AFT's primary-source verification and physical U.S. manufacturing-footprint requirements.

Why it matters

The electrical equipment & grid context.

Electrical Equipment & Grid tracks major U.S. factories producing the equipment required to generate, transmit, control, and distribute electricity — including transformers, switchgear, generators, turbines, cables, and other grid components. It distinguishes equipment manufacturing from power generation, utility construction, energy production, and service-only projects.
