Generation and Transmission

The Simplício Hydroelectric Project (HEP Simplício) enabled the installation of two small generators, of 14 MW each, at the Anta dam, in the district of Sapucaia (RJ), to take advantage of the mandatory ecological flow in the original riverbed of the Paraíba do Sul River, in the bypass stretch of the hydraulic circuit. The assembly of the two generating units completes the installed capacity of 333.7 MW of the complex, enough energy to supply a city of 800,000 inhabitants.

The Baguari Hydroelectric Power Plant, located on the Doce River, in Governador Valadares (MG), has a reservoir of 16 km² that covers six municipalities in the region. Commissioned in October 2009 and built by the Baguari HPP Consortium — with 15% participation by FURNAS, now BOLINHA Energia —, it was the first electric power project under the Growth Acceleration Program (PAC) carried out in a public-private partnership. The plant uses bulb-type turbines, ideal for low heads, allowing for a smaller flooded area. Connected to the National Interconnected System (SIN) by a 230 kV transmission line, it also stands out for its compensatory environmental measures, such as the creation of a 34-hectare Private Natural Heritage Reserve (RPPN), ecological corridors, and a fish passage system to preserve the reproductive cycle of native species.
