Partnership for Portuguese floating offshore wind tender

Ocean Winds, the international company dedicated to offshore wind energy, and Martifer Renewables & Energy, a key industry player, are thrilled to announce their strategic partnership to jointly participate in Portugal's first tender for offshore wind farms.

This collaboration brings together Ocean Winds' extensive international experience in developing and operating offshore wind farms, including the unique operating floating offshore wind farm in Portugal, WindFloat Atlantic; with Martifer Renewable & Energy's in-depth knowledge of the Portuguese market, supported by the industrial leadership of Martifer Group. By developing together cutting-edge floating offshore wind farms that will provide sustainable and clean energy solutions, they aim to contribute significantly to Portugal's renewable energy targets of 2 GW by 2030, aligned with the National Energy and Climate Plans (NECPs) of the European Union.

STRATEGIC PARTNERSHIP

ENERGY | HYDROGEN

GREEN.H2.ATLANTIC

It aims at the production of green hydrogen in Sines, with a 10% participation of Martifer Group, through the conversion of the old coal-fired plant into a green hydrogen production centre.

Application to the EU programme "Innovation Fund Large Scale Projects - Innovative Electrification in Industry and Hydrogen" was approved for funding, around 62 million Euros. In addition to the 30 million Euros already granted by the "Green Deal - Horizon 2020" programme.

Total planned funding of around 92 million Euros compared to the investment volume of more than 150 million Euros.

The financial contribution will substantially strengthen the viability and financial strength of the project, whose final investment decision (FID) is scheduled for late 2025, or early 2026.

The project was recognised by the Portuguese Trade & Investment Agency (AICEP) in September 2022 as a Potential National Interest project.
