High-voltage switchyard and electrical substation equipment

Electrical Engineering

Power systems designed for safe and dependable plant operation

PASAPCO provides electrical engineering for industrial projects, from concept development through commissioning. We establish how power is distributed across a facility, assess its operating and fault conditions, and develop the designs needed to supply and protect plant equipment. Our scope also extends to procurement and site activities, so electrical requirements are carried through equipment selection, installation, and energization.
