About Us

Our Foundation

Trecento was founded in July 2014 by Carmen Williams, a financial manager with extensive experience in the South African electrical industry. Carmen’s knowledge of the power generation sector led to a productive partnership with Simon Guidetti, who is a veteran engineer and transformer specialist.
