JINAN -- East China's Shandong province has put 1,507 charging stations for new energy vehicles (NEVs) into service as of the end of May, the State Grid Shandong Electric Power Company said on Thursday.

A total of 9,396 charging piles have been installed so far, covering all 16 cities across the province, which plans to build up to 100,000 charging piles by 2022.

Consisting of four charging piles, a vertical axis wind power generator, a solar photovoltaic station and balance of plant, a self-consistent high-power charging station on microgrid technology, first of its kind in China, went into operation earlier this week, the company said.

Shandong currently has about 250,000 NEVs, according to statistics from the provincial department of industry and information technology.

Under China's 13th Five-Year Plan (2016-2020), the country, with more than 600,000 charging piles installed so far, will build a nationwide charging station network to power 5 million NEVs by 2020.
