Integrate to cut energy wastage
Print Edition
A new report says China should pilot renewable energy integration policies similar to those used in Germany and Texas in the Beijing-Tianjin-Hebei region to transmit excess energy and cut wasted wind power.
Renewable energy integration will be fundamental to China’s transition to a low-carbon economy. Although China now leads the world in installed capacity of wind and solar power, curtailment — or energy waste — remains a severe challenge preventing its full use, said a report released by the Paulson Institute, a think tank devoted to sustainable growth.
The report pointed out that the wind and solar energy output of Hebei Province’s Zhangjiakou outweighs the small city’s demand, leading to high rates of curtailment. The city, located near Beijing, is China’s first nationally designated renewable energy demonstration zone.
The institute suggested China could learn from Germany and Texas by establishing Beijing-Tianjin-Hebei as a pilot for regional renewable energy integration, explicitly linking renewable energy produced in Zhangjiakou with centers of high electricity demand such as Beijing and Tianjin.
Germany and Texas achieved very low rates of curtailment last year, 1 percent and 0.5 percent respectively, as they reformed transmission planning, power dispatch and spot markets, the report said.
