Iberdrola added to its growing offshore wind ambitions in Asia with a deal that could see it join up to 3.5GW of Philippines projects.

The Spain-based green power giant has taken an option to enter five projects under development by Swiss group Stream Invest and local player Triconti ECC Renewables.

The early-stage projects have all secured a wind energy service contract – a key permit to begin development activities from the Philippines Department of Energy, said Iberdrola.
