en.Wedoany.com Reported - A key milestone was recently achieved for the Morro do Chapéu project in Brazil's Bahia state, with the official commissioning of the 500-kilovolt Medeiros Neto II–João Neiva 2 power transmission line. This new infrastructure, stretching 283 kilometers with a total investment of approximately R$480 million, marks the completion of the second batch of projects under the 2020 power transmission auction.

The transmission line project primarily addresses the growing demand for regional power flow, especially for the transmission of electricity from newly built wind and solar power plants. With the continuous increase in renewable energy installed capacity, the transmission system requires upgrades and modifications to ensure the safe and efficient transmission of the additional power. The new line also enhances power supply reliability, reducing the risk of voltage fluctuations or emergency load shedding in southern Bahia during unforeseen events.

The Morro do Chapéu project comprises four main transmission lines with a total length of 1,061 kilometers, along with the construction of a new substation providing an additional 300 MVA of capacity. Synchronous compensators are also being installed to maintain system stability. These facilities are distributed across the states of Bahia, Minas Gerais, and Espírito Santo, forming part of the New Growth Acceleration Program, which allocated approximately R$2 billion for this set of projects.

The newly operational 500-kilovolt line connects the Medeiros Neto II substation in Bahia to the João Neiva 2 substation in Espírito Santo, creating a more robust and resilient transmission corridor. This connection strengthens the stability of the Brazilian power grid, creating better conditions for sustainable growth and ensuring the seamless integration of the expanding renewable energy sector into the national electricity system.
