China's largest offshore project now online

CHINA: Longyuan Power last week connected to the grid 99.3MW of wind turbines in a pilot intertidal wind farm in Rudong, Jiangsu province. Added to the 32MW already online since September, this makes Rudong the largest offshore wind farm in the country.

Longyuan, which is China's largest wind-power developer, started building the Rudong project in June 2009. Its first stage — 150MW at a cost of CHY 2.5 billion ($397 million) — is due for completion in March, according to Zhang Gang, general manager of Longyuan Jiangsu Offshore Wind Power.

Zhang said the wind farm would generate 330 gigawatt hours of electricity for the grid, avoiding up to 267,000 tonnes of CO2 emissions.

Xie Changjun, general manager of Longyuan, said: "Our construction of the Rudong pilot intertidal wind farm will lead the way for China to develop offshore wind power, particularly in site selection, planning and design, and installation and maintenance." He added that China would soon be able to develop offshore wind power on a large scale.

China's only other offshore wind farm in commercial operation is the Shanghai East Sea Bridge, with 102MW. It went into operation in June 2010.

According to the National Energy Bureau, China will construct 5GW of offshore wind projects by 2015, representing 5% of its total wind installed capacity. The country aims to have 30GW of offshore wind by 2020.

Update 11 January — among the 99.3MW recently connected to the grid, about 50MW came from Siemens in the form of its 2.3MW turbine. The rest came from Sinovel.

The previous 32MW turbines were made by Guodian United Power, Sinovel, Mingyang, Shanghai Electric, Goldwind, Envision Energy, Sany Electric, and Chongqing Haizhuang as part of a trial to judge performance.
