• An Electrical Engineer with African roots created Vianne. He traveled the world and came to the simple conclusion that without a continuous and reliable source of electrical energy, sustainable development is impossible. Vianne Inc. was established in the USA in October 2009. The initial years were focused on activities in the USA. There, we learned and understood the high standards and professionalism that we have been applying in Africa since 2012.
