Release: November 2020
Volume: 25 Pages

An essential guide to the technical and testing obligations for the connection of wind power generators to the transmission network in Brazil
Growing demand, recent regulatory reform, the proliferation of financing options, and maturing supply chains have put wind power at the forefront of Brazil’s necessary energy revolution. Grid connection is the critical step in bringing projects online, where specific technical and testing requirements must be adhered to for projects to avoid delays and additional cost.
