He further honed his regulatory and technical expertise through advanced training in two internationally recognized programs: the PURC/World Bank International Training Program on Utility Regulation and Strategy (University of Florida, 2018) and the KOICA Fellowship on Renewable Energy Development (Korea Institute of Construction Technology Education, 2015).
Throughout his career, Ambrose Tillett has consistently demonstrated a deep commitment to expanding energy access, promoting sustainability, and upholding regulatory integrity. His interdisciplinary experience and leadership continue to make a significant impact on Belize’s energy transformation and regional regulatory development.
