The electric power industry in China is working on improving its operational performance to save energy and reduce emissions. A new study looked at how effective and efficient different regions are at generating electricity. They found that it's important for power plants to not only be efficient but also effective in meeting electricity demand. By analyzing data from 2006 to 2010, the researchers discovered that improving electricity sales is crucial for enhancing effectiveness. Overall, efforts to transmit and reallocate electricity between regions in China are effective, and increasing electricity generation can help boost sales.
