Potencia Partners Inc is pleased to announce Rogelio Carlos Martinez Villarreal as Technical Director and Senior Transformer Consultant.
Rogelio brings over four decades of transformer engineering, R&D, and production leadership to Potencia, with senior roles at Virginia Transformer, Georgia Transformer, GE, Siemens Transformers Mexico, and Prolec-GE. His expertise spans dry- and oil-type transformer manufacturing, advanced plant automation, and large-scale optimization across Latin America and the U.S.
As Technical Director at Virginia Transformer West, Rogelio oversees Quality, Engineering, Production, and Testing across both plants, while supporting the CTO group in detailed failure analysis, technology development, and customer support for new projects.
Previously, as Engineering Director at Georgia Transformer, he led a 22-engineer team responsible for the design of power and autotransformers up to 450 MVA, 500 kV, and 1550 kV BIL. He implemented full 3D mechanical and electrical design automation to ensure dielectric clearances and eliminate interferences, reducing non-conformance reports by 80% year over year.
Earlier at GE, Rogelio served as Technology Manager, directing major R&D programs totaling over $7 million in DOE-backed investment and achieving $9 million in design and efficiency savings between 2009 and 2016. He introduced new ultra-efficient 300 kVA and 750 kVA transformer lines and led development of harmonic-resistant designs.
During his decade at Siemens Transformers Mexico, Rogelio managed a team of 46 engineers and served on Siemens’ global Engineering Steering Committee, coordinating design practices across 19 plants worldwide. He implemented optimization systems that reduced material use by 3%, trained engineers in Six Sigma methodology, and oversaw R&D projects that made the Mexico plant technically independent from its Canadian counterpart in 2000.
At Prolec-GE, where he began his career, Rogelio developed design optimization programs for power and autotransformers up to 500 kV, prepared complex proposal designs, and represented the company in technical meetings across the Americas.
Recognized for bridging design innovation with manufacturing excellence, Rogelio continues to advance reliability, safety, and cost efficiency throughout the global transformer industry.
