China should accelerate construction of an extra-high-voltage transmission line to deliver power generated by new energy, according to a senior official.

"The so-called overcapacity problem of China's new-energy industry does not refer to energy, but the equipment for new-energy production," said Zhang Guobao, former director of the National Energy Administration under the National Development and Reform Commission, during an interview with Xinhua News Agency.

He said domestic new-energy equipment manufacturing companies have met difficulties in exporting their products, which has resulted in overcapacity in the domestic market, but China's new-energy operators are "doing fine".
