Cangnan #1 - phase 1

Project Overview

• Name: Cangnan No.1 Offshore Wind Power Project
• Location: Yanting, Cangnan, Wenzhou, Zhejiang, China, in the East China Sea.

Ownership and Operation

• Owner: China Resources Power Investment Co., Ltd., a wholly owned subsidiary of China Resources Power Holdings Co., Ltd..
• Operator: China Resources Offshore Wind Power (Cangnan) Co., Ltd..

Capacity and Turbines

• Total Capacity: The entire project has a planned installed capacity of 400 MW, but Phase 1 specifically involves:
  • 24 Turbines: Each with a nameplate capacity of 6.25 MW, supplied by Envision Energy.

Construction and Operation Timeline

• Construction Start: The project construction commenced in 2021.
• Commercial Operation: The project was expected to enter into commercial operation by the end of December 2022.

Technical Details

• Foundation Type: The turbines are mounted on fixed monopile foundations.
• Inter-array Cable: The turbines are interconnected by 35kV inter-array cables.
• Annual Power Generation: The entire project is expected to generate 1.2 billion kWh (1,200,000 MWh) of electricity annually, though this figure includes both phases.

Environmental Impact

• Carbon Emissions Reduction: The project is expected to offset 800,000 tons of carbon dioxide (CO2) emissions per year.
• Resource Savings: Compared to conventional coal-fired thermal power units, the project can save about 422,000 tons of standard coal and 4 million cubic meters of fresh water annually.

Geographical and Sea Conditions

• Area: The project is spread over an area of 63.7 km².
• Sea Conditions: The project is one of the most complex offshore wind power projects in China due to its sea conditions and sea area geology.

Additional Phases

• While Phase 1 involves 6.25 MW turbines, Phase 2 will be equipped with China Shipbuilding Group Haizhuang Wind Power H210-10 MW turbines, consisting of 25 turbines.
• A Phase II expansion, adding another 204 MW, commenced in Q1 2024 and is expected to be completed by Q4 2027.
