The Brazilian energy sector is seeing various developments in hydroelectric infrastructure and grid maintenance.

In the Mato Grosso and Goiás border region, Nascente Renováveis has recorded its intent with the National Electric Energy Agency (Aneel) to build the Santa Rita Small Hydroelectric Plant on the Araguaia River. The project aims for a 14,000-kilowatt capacity. Aneel recently denied a competing registration for the same water resource.

In Espírito Santo, Santa Maria Participações is investing R$ 60 million to develop the Km 47 hydroelectric plant on the Cricaré River, which is expected to provide energy for approximately 12,000 homes. Meanwhile, in Rio de Janeiro, Enel Rio is conducting extensive tree pruning operations to improve grid resilience against extreme weather.
