Atlas Renewable Energy Halts $1 Billion Solar Projects in Brazil Due to High Curtailment Rates
Atlas Renewable Energy, backed by BlackRock, has decided to freeze $1 billion in planned solar investments in Brazil. The decision comes as a result of high curtailment rates, which have become a significant bottleneck for renewable energy expansion in the country. Curtailment rates for solar projects reached approximately 27% in 2025, significantly higher than the previous year, according to Rystad Energy estimates. The national grid operator's frequent rejection of renewable power has exacerbated the issue, leading Atlas to put on hold 1.5 gigawatts of planned construction. The company, which has one of the largest fleets of renewable energy projects in the Americas, faces challenges due to the lag in transmission infrastructure development, which is unable to keep pace with capacity additions.
