Qinghai province use wind energy for 9 consecutive days
Wang.C.S  2018.07.02



China has set a world record in Qinghai province, where 6 million people used nothing but clean energy for nine consecutive days - a testament to China's commitment to a low-carbon future.

The trial lasted from June 20 to midnight on June 28 in the province. During the 216-hour trial, the province ran solely on electricity generated from wind, solar and hydropower stations.

It was the second clean energy trial for the whole province. In June last year, it relied solely on renewable energy for seven consecutive days, beating Portugal's 107-hour clean energy effort in May 2016.

According to China State Grid's Qinghai branch, electricity consumption during the nine days totaled 1.76 billion kilowatt-hours, equivalent to coal use of 800,000 metric tons, and cut emissions of 1.44 million tons of carbon dioxide.

China is spearheading the global fight against climate change by enforcing strong environmental policies. According to the commitment it made in the Paris Agreement, it will cut carbon emissions per unit of GDP by 60-65 percent by 2030 from 2005 levels.

Qinghai's efforts represent a nationwide shift toward low-carbon energy use. During the nine-day period, hydropower stations supplied around 80 percent of the electricity, with the rest produced by solar and wind power facilities, said Qi Taiyuan, general manager of State Grid Qinghai Electric Co.

Around 3 percent of the power generated during the period was from coal-fired plants and was transmitted to neighboring Gansu province, Qi said. A minimal amount of coal-fired power plants were kept running because they were needed to stabilize the grid in case of fluctuations and to avoid damaging electrical infrastructure, he said.

"During the nine days, we achieved zero emissions related to power use in Qinghai," said Xu Yourui, director of the company's coordination center.

Encompassing the headwaters of three major rivers - the Yellow, Yangtze and Lancang - Qinghai has abundant hydroelectric and solar-power facilities.

"Environmental protection is critical in Qinghai because of the river sources. There are strong reasons for China to cut emissions in Qinghai, and to promote clean energy and maximize the efficiency of clean energy facilities," Qi said.
