List of Top 7 Biggest Upcoming Wind Farms in Italy 

HyMed Offshore Wind Farm

The HyMed Offshore Wind Power Plant is a proposed floating wind and green hydrogen project planned in ultra-deep waters off the coast of Italy. Developed by Aquaterra Energy and Seawind Ocean Technology, the project aims to become one of the world’s largest floating offshore wind farms.

It will have an installed capacity of 3.2 GW, including more than 1 GW dedicated to green hydrogen production for export. The development aligns with Italy’s growing offshore renewable ambitions and is scheduled to begin production by 2027.

HyMed will use Seawind Ocean Technology’s two-bladed floating wind turbines and Aquaterra Energy’s green hydrogen production systems. The offshore infrastructure will include turbine foundations fixed to the seabed, meteorological equipment, offshore collector substations, inter-turbine cables, and export cables connecting to shore.

Onshore works will feature a transition joint bay, underground cabling, and an onshore substation to support power transmission and hydrogen processing. The hydrogen plant will have an electrolysis capacity of 1,000 MW, enabling large-scale hydrogen generation for transport to shore via pipeline or vessel.

The total investment for the project is estimated at USD 4.8 billion. Development is being pursued privately, and the partners are currently advancing through the first phase of permitting, grid connection, and environmental assessments. Construction is planned to begin in the fourth quarter of 2025, with completion and full operation expected by 2027.

Med Wind Offshore Wind Farm

The Med Wind Floating Offshore Wind Park is one of the largest upcoming floating offshore wind projects in Italy, which will be developed by Renexia. The wind farm has a capacity of 2.8 GW and delivers clean energy to 3.4 million households in Italy. The wind project in the Strait of Sicily will meet about 3% of Italy’s national energy demand and offset 2.7 million tons of CO₂ emissions annually.

The offshore wind farm will feature 148 floating wind turbines, each with an 18.8 MW capacity. Med Wind operates with turbines anchored around 60 to 80 kilometers from the Italian coastline and with water depth between 300 and 600 meters. The project will include offshore substations and a 700-kilometer export cable connecting to mainland Italy to transfer renewable electricity.  

The Italian wind farm will have a turbine layout and foundation design based on Technip Energies’ INO15 floating technology. This will help the wind farm to reduce seabed disturbance and preserve the local marine ecosystem.

In October 2024, Renexia signed a front-end engineering design (FEED) contract with China’s Mingyang Smart Energy. The contract followed the joint signing of a memorandum of understanding (MoU) with the Italian Ministry of Enterprises to develop a factory in Italy for the new 18 MW MySE turbines. Renexia has also signed key contracts with Technip Energies and Aker Solutions for FEED design. 

The Med Wind project submitted its Environmental Impact Assessment (EIA) application in 2024, and construction, along with the final investment decision (FID), is expected to start in 2025. Site construction work is anticipated to be completed by 2026, and the assembly of foundations and turbines is scheduled to begin in 2027. The project aims to achieve full commissioning by 2032.

Barletta Offshore Wind Farm

The Barium Bay Offshore Wind Project, also known as the Barletta Offshore Wind Farm, is a large-scale floating wind development planned in the Adriatic Sea between the cities of Bari and Barletta in Italy’s Apulia region. The project will have a total installed capacity of 2.2 GW and generate more than 3 billion kWh of clean electricity annually, enough to power over one million homes in Italy.

The project is being developed through a joint venture between Galileo Energy and Hope Group. In May 2025, the Italian Ministry of the Environment and Energy Security granted the project a positive environmental impact assessment (EIA) decree. This approval marked a major milestone, as Barium Bay became the largest offshore wind project in the Mediterranean to achieve such clearance.

Following the EIA approval, the project is now eligible to enter the renewable energy auction process under Italy’s FER 2 Decree. This program provides long-term Contracts for Difference for up to 3.8 GW of offshore wind capacity nationwide.

Sardinia North-East Offshore Wind Farm

The Sardinia North-East Offshore Wind Farm is a proposed floating wind project planned in the Tyrrhenian Sea, off the northeast coast of Sardinia. The project is expected to have a capacity between 1.95 GW and 2.15 GW. It remains in the early planning phase, with key site and feasibility studies still underway.

The wind farm will use floating turbine foundations suited to the deep waters of the Tyrrhenian Sea. The project is being developed by AvenHexicon Srl, a joint venture between Sweden-based Hexicon AB and Italy’s Avapa Energy, with Hexicon holding a 50% share. The partnership combines expertise in floating wind technology and local energy project development.

Sardinia North-East is currently at the “announced” stage and has not yet advanced into Italy’s active offshore project pipeline. Earlier plans suggested construction could begin in 2025, followed by commercial operation in 2029, though this schedule is subject to revision as permitting and planning progress.

Nereus Offshore Wind Farm

The Nereus Offshore Wind Farm is a large-scale floating wind project planned for the Southern Adriatic Sea off the coast of Puglia, Italy. Developed by Nereus S.r.l., with involvement from Nexta Capital, the project is designed to reach a total capacity of 1,800 MW. It will feature 120 turbines, each rated at 15 MW, making it one of the most ambitious offshore wind projects in Italy.

The wind farm will be located offshore with a grid connection planned near the municipality of Barletta. Its strategic position in the Adriatic Sea is expected to take advantage of consistent offshore wind conditions, enabling stable power generation.

Nereus has been highlighted in several research studies focusing on offshore wind development and optimization in Italy. The project remains under development as technical, environmental, and permitting processes continue to progress.

Abruzzo 1 Floating Wind Farm

The Abruzzo I Floating Offshore Wind Farm is a 1,760 MW offshore wind project planned in the Adriatic Sea. The wind farm is located approximately 20 nautical miles (32 km) off the coast of Abruzzo, Italy. The wind farm is developed by AGNES, Qintx Holding, and Saipem, each holding a 33.33% ownership stake.

The project is currently in the announced stage, and construction is expected to begin in 2025. The wind farm will feature 160 floating wind turbines, each with an 11 MW capacity.

The floating wind turbines have a height of 170 meters with a rotor diameter of 260 meters, designed to capture strong offshore winds. The wind farm is expected to be completed in 2029.

ABEI – Puglia Offshore Wind Farm

The ABEI – Puglia Offshore Wind Farm is a proposed large-scale wind project planned in the Ionian Sea, approximately 28 kilometers off the southern coast of Italy’s Puglia region. The development will consist of 115 offshore wind turbines, each with a capacity of 15 MW, for a total installed capacity of 1,725 MW.

The project is being developed by AEI Wind Project VI S.r.l. and includes all related grid connection works to the Italian National Transmission Network (RTN). It will be located offshore between the municipalities of Salve, Morciano di Leuca, and Patù in the province of Lecce, with onshore connections extending across several nearby municipalities, including Gallipoli, Ugento, and Presicce.

AEI Wind Project VI S.r.l. submitted its request for a maritime concession on 24 August 2023 to enable the construction and operation of the wind farm. The project entered the scoping phase under the PNIEC-PNRR procedure later that month, initiating the environmental and technical assessment process.

Conclusion

Italy's offshore wind sector now has 81.3 GW under environmental review, spread across 128 projects, demonstrating remarkable growth in just a few years. Leading the charge are Regolo Renovables Srl (6,264 MW), AvenHexicon Srl (5,550 MW), Acciona Energía (4,995 MW), Ninfea Renovables Srl (4,545 MW), and Renexia SpA (4,173 MW) companies that together account for a substantial share of the national offshore pipeline.

Despite this momentum, challenges remain. The connection of new wind farms to the national grid, limited port capacity for assembly and logistics, and lengthy environmental permitting continue to slow progress. Italy’s Integrated National Energy and Climate Plan (PNIEC) targets 2.1 GW of offshore wind by 2030, while the EU’s Fit for 55 initiative sets a more ambitious 8.5 GW target for the same period. Bridging this gap will require faster approvals and stronger infrastructure planning.

The Apulia region, with 3.8 GW of projects currently under evaluation, stands out as a strategic hub for Italy’s offshore wind expansion. As permitting advances and investments accelerate, these projects are set to transform Italy’s coastlines into a cornerstone of Europe’s clean energy future.
