Formosa 2

Formosa 2 Offshore Wind Farm Profile

Location

The Formosa 2 offshore wind farm is situated in the Taiwan Strait, approximately 3.8 to 9.5 kilometers off the west coast of Miaoli County, Taiwan. It is located near the Formosa 1 wind farm.

Ownership and Development

The project is jointly developed by:

• JERA Co., Ltd. (49% ownership)
• Macquarie’s Green Investment Group (26% ownership)
• Synera Renewable Energy, a subsidiary of Swancor Holding (25% ownership).

Capacity and Turbines

The Formosa 2 wind farm has an installed capacity of 376 MW, comprising 47 wind turbine generators (WTGs). Each turbine is a Siemens SG 8.0-167 DD model, with a nominal power of 8 MW, a rotor diameter of 167 meters, a hub height of 116.4 meters, and a blade length of 81.5 meters. These turbines are installed on jacket foundations in water depths of approximately 55 meters.

Construction and Milestones

• Construction Start: Onshore construction began in November 2019, and offshore installation activities started in 2020.
• Foundation Installation: The installation of the jacket foundations was completed in 2022.
• Turbine Installation: All 47 turbine installations were completed by January 2023, and all turbines were connected to the grid by March 2023.
• Commercial Operation: The wind farm commenced full commercial operation in September 2023.

Power Purchase Agreement

The power generated from the Formosa 2 wind farm is sold to Taiwan Power Company under a 20-year power purchase agreement at a rate of $0.188 per kWh. The contracted capacity is 376 MW.

Environmental Impact and Benefits

The Formosa 2 wind farm is expected to generate enough electricity to power approximately 380,000 households per year. It is projected to offset 18,750,000 tons of carbon dioxide emissions annually, contributing significantly to Taiwan's transition towards renewable energy.

Contractors and Suppliers

Several contractors and suppliers were involved in the project:

• Jan De Nul Group: Responsible for the engineering, construction, and installation of the foundations and subsea cables.
• Saipem and Sembcorp Marine: Fabricated the jacket foundations.
• Tarpon Energy Services: Undertook electrical installation works.
• Fortune Electric: Supplied the onshore power system.
• Taiwan International Ports: Provided the assembly pier rental.
• JF Renewables’ subsidiary, EDS HV Group: Provided high-voltage support services.
• DORIS: Provided consultancy services including WTG technical and commercial package management, foundation design, and site investigation.
• EEW Group: Supplied foundation components.
• MMA Offshore: Conducted pre-installation noise mitigation surveys.
• Correll Group: Provided cable repair services.

Local Engagement and Training

The project has a strong focus on localization, working closely with local consultancies such as Unitech, CECI, and Sinotech. It has also collaborated with universities like National United University, National Cheng Kung University, and National Taiwan Ocean University for site surveys and analyses. Additionally, Formosa 2 has established the “Formosa 2 offshore wind expertise program” and marine mammal observer training programs for local fishermen.

Regulatory Approvals

The project obtained necessary approvals, including the System Impact Analysis (SIA) with Taiwan Power Company YingPan substation, the Environmental Impact Assessment (EIA) process, the Establishment Permit (EP), and the Construction Permit (CP) from the Ministry of Economic Affairs.
