South America is set to see significant growth in onshore wind capacity over the next decade, with 40 GW of new capacity expected to be installed by 2033, doubling the region's cumulative installations to 79 GW. Brazil leads this expansion, followed by Chile and Argentina, supported by commercial and industrial power purchase agreements. The region faces limited growth due to policy-driven renewables overbuild in Brazil and Chile, necessitating grid upgrades and increased power demand to drive market recovery. Wind and solar power projects in Brazil, predominantly in the northeast region, are thriving due to tax incentives, technology cost reductions, and ESG guidelines, contributing to an energy surplus with potential expansion into green hydrogen and datacenter markets.
