Na Intersolar South America, no Brasil (25 a 27 de agosto), cerca de 20 empresas chinesas de armazenamento de energia expuseram. A Chuneng New Energy assinou acordos com quatro parceiros, incluindo memorandos de entendimento com a Intermepro, da Argentina, e a ION Energy e a JSN Energia, do Brasil, além de um acordo-quadro de 1,5 GWh de células com a Windey Energy para fornecer células para sua primeira planta de armazenamento no exterior, na Bahia, Brasil. Com uma rede frágil, uma taxa de corte de 20,6% e os segundos preços residenciais de eletricidade mais altos do mundo, o Brasil lançará o maior leilão nacional de armazenamento da América Latina (cerca de 18 GW na primeira rodada) em dezembro de 2026, atraindo CATL, Trina, Hithium, CLOU, Gotion e Great Power a expandirem-se localmente.
