According to its Wikipedia entry, the plant harnesses the flow of the Paraná River basin to generate electricity for the region.
A Brief History
- Construction Era – The dam was built as part of Brazil’s mid‑20th‑century push to expand renewable energy capacity. While exact dates are not publicly detailed, the plant reflects the country’s broader commitment to hydroelectric development during that period.
- Naming – It bears the name of Mário Lopes Leão, a notable figure in Brazil’s energy sector, honoring his contributions to the nation’s electrification efforts.
Why It Matters
Brazil relies heavily on hydroelectric power, which accounts for roughly 60 % of the country’s electricity generation. Facilities like the Mário Lopes Leão dam play a crucial role in stabilizing the grid, especially in the state of São Paulo, the nation’s most populous and industrialized region. For travelers, the dam provides a tangible glimpse into how Brazil balances modern energy needs with its abundant natural resources.

Best Time to Visit
The climate around Promissão is humid subtropical, with distinct wet and dry seasons. Here’s when you’ll get the most out of your visit:
