Portugal aims to stage a debut floating wind power auction this summer, its environment and energy transition minister told media.

The Iberian nation plans to promote projects to put in place 3 to 4 gigawatts of capacity by 2026, Joao Matos Fernandes told Reuters news agency.

"Portugal wants to become a major exporter of renewable energy in the future and therefore has to bet on wind offshore," he reportedly said, adding that floating projects in deep waters could avoid the environmental permitting challenges seen for onshore renewables.
