The countries signed a memorandum of understanding in April for the 7.6-gigawatt (GW) project, but many Peruvians are opposed to it. The agreement proposes allowing Brazil to study, finance, build and operate the plants in Peru, with most of the energy destined for Brazil.

“We do not want, we will not accept, we firmly reject the Brazilian model for the Amazon region,” says Alfredo Novoa-Peña, president of the Peruvian renewable-energy association, Apeger.
