China’s biggest onshore wind farm has gone into operation in Zhangjiakou, Hebei province. It’s part of a national effort to increase the use of renewable energy. The 160-meter high turbines are intended to ensure that all the power supply for venues in Zhangjiakou for the 2020 Winter Olympics will come from clean energy. The generator has been integrated to the national power grid. Its intelligent control system can ensure smooth distribution of electricity to the entire grid.

Capacity is three times that of the unit formerly deployed across China. The unit generates 5,000 kilowatt-hours of electricity an hour. Daily maximum power generated reaches 120,000 kilowatt-hours. That amount could meet the demand of nearly 10,000 households. The city is part of the integration plan of Beijing-Tianjin-Hebei.

It’s the only demonstration city for renewable energy in the country. Zhangjiakou plans to increase its share of renewable energy from 7 percent in 2014 to 30 percent by 2020. It hopes renewable energy can meet half of the city’s needs by 2030. That would mean a reduction of 85 million tons of carbon dioxide and sulfur dioxide.
