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.
