Nicolas Schmutz, Founder and CEO of Reuniwatt

In 2010, solar energy was developing very fast in Reunion Island. The grid operator was worried about the potential impact on the grid stability, and stopped connecting new solar plants to the grid. Something had to be done to offer a safe and massive penetration of solar on the grid. That’s when Reuniwatt was founded.
As a pioneer in solar forecasting, it was Nicolas’ goal to develop the best skills in earth observation in order to deliver the best in class irradiance reconstruction. He strives to implement original thinking in the technical field: Innovation is the cornerstone of Reuniwatt’s strategy, which is why we’re always engaged on R&D partnerships and perform hands-on research at Reuniwatt.
