This article highlights that integrating renewable energy sources into the Brazilian electrical system requires an innovative approach tailored to its unique characteristics. Given the country's vast territorial expanse and the complexity of its transmission system, there is a need to reformulate the interconnection process to accommodate the growth of intermittent sources such as wind and solar. The proposed solution emphasizes the implementation of an auction procedure for connecting to transmission points. This "competitive capacity" method, which includes a participation deposit by generators, aims to ensure more equitable and efficient access to the transmission network. This approach seeks to improve transparency and predictability in the process, while mitigating speculation and optimizing the use of available transmission capacity. This proposed model could serve as a reference for other countries facing similar challenges in incorporating renewable energies into their electrical systems.
