Mauricio Tolmasquim is a member of the Board of Directors at Eletrobras. He previously served as the first Chief Energy Transition and Sustainability Officer at Petrobras, where he established and structured the new directorate.

He was CEO of Empresa de Pesquisa Energética (EPE) for more than 11 years, leading studies to support national energy planning across electricity, oil, gas, and biofuels. Under his leadership, Brazil successfully held 37 energy auctions, contracting over 92 GW of new generation capacity. He also coordinated the studies that underpinned Brazil’s Nationally Determined Contributions (NDCs) submitted to the UNFCCC in 2015 and supported the development of the regulatory framework for the pre-salt oil sector.

Earlier in his career, Tolmasquim served as Deputy Minister and Interim Minister of Mines and Energy, where he led the technical group that designed Brazil’s 2004 power sector reform — shifting the market model toward long-term competitive contracting. He also served on Brazil’s National Energy Policy Council and the Power Sector Monitoring Committee.

He was a visiting researcher at the Inter-American Development Bank (IDB) and at Harvard Kennedy School’s Electricity Policy Group. Before joining Petrobras, he was a Full Professor in the Energy Planning Program at COPPE/UFRJ, where he supervised more than one hundred master’s and doctoral theses and lectured at over a thousand national and international events.

Tolmasquim has served on the boards of several major companies and institutions, including Itaipu Binacional, Furnas, EPE, Vigor, and the Fiscal Council of Klabin. He holds degrees in engineering and economics, a master’s in energy planning from COPPE/UFRJ, and a PhD from the École des Hautes Études en Sciences Sociales (France).

He has received numerous honors, including the title of Grand Officer of the Order of Rio Branco from Brazil’s Ministry of Foreign Affairs and election to the Brazilian Academy of Engineering. He was named one of Latin Trade Magazine’s “25 Transformative Leaders in Latin America,” among the “100 Most Influential in Energy” (Sustainability category, 2024), recognized by Recharge magazine as a Thought Leader, and ranked among the 30 most influential global figures in the wind sector by Wind Power Monthly.
