HydroRenewable

Promissão (Mário Lopes Leão) ranks as Brazil's 146th largest power generation facility, contributing 264 MW to the country's extensive energy portfolio. This hydroelectric plant, commissioned in 1975, is part of Brazil's commitment to renewable energy, particularly with hydro as the dominant fuel source, accounting for a remarkable portion of the national capacity of 250,382 MW. With a ranking of 93rd among 720 hydro plants, Promissão holds a vital position within the hydroelectric landscape of Brazil. The facility's generation technology harnesses the power of flowing water, providing a sustainable and efficient means of electricity production. Promissão is strategically located near several other plants, including Nova Avanhandava (Rui Barbosa), which has a capacity of 347.4 MW, and various biomass plants like Chapadão Agroenergia (92 MW) and Equipav II (80 MW). This clustering of energy facilities underscores the regional reliance on diverse renewable resources, enhancing grid stability and energy security. Although Promissão represents only 0.11% of Brazil's total capacity, its role in the renewable energy sector is significant as the country aims for a greener energy future. The operator's long-standing experience since 1975 ensures that Promissão remains a reliable contributor to the national grid. Looking ahead, as Brazil continues to invest in renewable energy infrastructure, Promissão is well-positioned to bolster the country's efforts toward sustainability and environmental responsibility.
