The Agência Nacional de Energia Elétrica (ANEEL) and the Abradee Institute have opened registration for the 5th edition of the National Energy Efficiency Olympiad (ONEE) 2026. The competition aims to promote sustainability, conscious energy consumption, and natural resource preservation among students in Brazil. For this edition, the target audience has expanded to include students in the 1st and 2nd years of high school, alongside the existing participation of 8th and 9th-grade elementary students from both public and private schools. The program seeks to engage up to 660,000 participants. The competition structure consists of two main phases: online gamified digital challenges focused on sustainability and safety, followed by an objective theoretical exam. Participants can earn gold, silver, and bronze medals. Top performers in each state may receive prizes such as notebooks and all-expenses-paid trips to Brasília for the Olympic Week. New details indicate that the initiative is promoted through the Energy Efficiency Program (PEE), with Equatorial Piauí acting as the proposing company. The 2026 edition has also allocated over R$ 250,000 to reward teachers. Educators can be recognized in four categories based on pedagogical work and school engagement, with prizes including vouchers and participation in the BETT Brasil 2027 innovation event. Outreach efforts have already begun, such as a campaign by Equatorial Pará at the Marechal Rondon Basic Education School in Itaituba. Institutions must complete registration through the official portal by September 15. ## Timeline ### 2026-09-10: National Energy Efficiency Olympiad 2026 targets students and teachers in Brazil The National Energy Efficiency Olympiad (ONEE) 2026 is engaging Brazilian students and teachers through educational challenges and over R$ 250,000 in prizes to promote sustainable energy use. 3 sources. https://clstr.news/cluster/national-energy-efficiency-olympiad-2026-targets-students-and-teachers-in-brazil ### 2026-08-17: National Energy Efficiency Olympiad opens registration for 2026 Registration is open for the 2026 National Energy Efficiency Olympiad (ONEE) in Brazil, now including high school students to promote sustainability and conscious energy use. 3 sources. https://clstr.news/cluster/national-energy-efficiency-olympiad-opens-registration-for-2026 ### 2026-07-29: Brazil opens registration for 5th National Energy Efficiency Olympiad Brazil's ANEEL opens registration until 15 Sept for the 5th National Energy Efficiency Olympiad, targeting up to 660 000 students and culminating in a November awards ceremony in Brasília. 7 sources. https://clstr.news/cluster/brazilian-students-to-compete-in-international-ai-olympiad-in-kazakhstan --- Cite as: Brazil National Energy Efficiency Olympiad 2026.
