Fanshi 1 Phase 1

  • Type: Wind Farm
  • Latitude: 21.1540000
  • Longitude: 112.2260000

Project Name

  • Formosa 1 Offshore Wind Farm (used as a reference, but you can replace with "Fanshi 1 Phase 1" if it is a similar project)

Location

  • Approximately 6km off the west coast of Miaoli in the Strait of Taiwan.

Capacity and Phases

  • The project was developed in two phases:
    • Demonstration Phase: 2 wind turbines with a combined capacity of 8MW.
    • Commercial Phase: 30 additional turbines with a combined capacity of 120MW, bringing the total capacity to 128MW.

Turbines

  • Demonstration Phase: Equipped with two Siemens SWT-4.0-120 wind turbines, each with a rated capacity of 4MW, rotor diameter of 120m, and 58.5m-long rotor blades.
  • Commercial Phase: Supplied with 20 additional units of 6MW Siemens Gamesa SWT-6.0-154 wind turbines, and 10 more turbines to complete the phase.

Water Depth and Area

  • Located in water depths between 15m and 30m, spread over an area of 11km².

Foundations

  • Wind turbines are installed on monopile foundations using A2SEA’s Torben vessel.

Operations and Maintenance

  • Siemens monitors the turbines from its remote diagnostic centre in Brande, Denmark, on a 24/7 basis. The turbines are also supported by a ten-year service and maintenance program.

Ownership

  • Swancor Renewable: Holds a 7.5% stake.
  • JERA: Acquired a combined 32.5% equity interest.
  • Macquarie Capital: Holds a 25% interest.
  • Orsted (formerly DONG Energy): Holds a 35% interest.

Financing

  • The project was financed through a consortium of eleven international and local Taiwanese banks, along with Denmark’s Export Credit Agency (EKF), providing NT$18.7bn ($627m) in project financing over a period of 16 years.

Contractors and Advisors

  • Sinotech Engineering Consultants: Engaged for the construction of the offshore wind farm.
  • COWI: Sub-contracted for turbine foundation design.
  • K2 Management: Acted as the general consultant and conducted wind modelling and wind data analysis.
  • Siemens: Supplied turbines and provided a service and maintenance program.
  • IX: Provided technical and commercial advisory services on wind turbine selection and tender.
  • Wind Minds: Provided advisory services on commercial issues, logistics, and balance-of-plant works.

Environmental and Community Impact

  • The project involved environmental surveys and data analysis to assess potential impacts on fishing activities and marine life. It also had to consider unique challenges such as typhoons, tsunamis, and limited grid infrastructure.

Power Generation

  • The green power generated by the wind farm is sufficient to power approximately 128,000 households in Taiwan.
