World's largest double-row turbine arrangement, the Lijiaxia Hydropower Station, went into operation on Tuesday in northwest China's Qinghai Province, with a full capacity of two million kilowatts.

Located at the border of Jainca County and Hualong County in northwest China's Qinghai Province, Unit 5 of Lijiaxia Hydropower Station passed a 72-hour trial operation and was officially put into production at 10:16 p.m. on Tuesday, China Media Group reported.

It marks the first time that China has adopted a double-row turbine arrangement, which is also the world's largest of its kind.

The Lijiaxia Hydropower Station has a single unit capacity of 400,000 kilowatts. Unit 5 uses an evaporative cooling scheme of a new domestic cooling medium, which can effectively reduce stator temperature rise to further improve the peak and frequency regulation capabilities of the power station.

In addition, Unit 5, as an important supporting power supply for an ultra-high voltage transmission channel, mainly cooperates with the intermittent power supply operation of photovoltaic and wind power generation.

It stabilizes the output variations of wind and photovoltaic power generation, and then converts new energy power generation into safe, stable and high-quality power to deliver clean energy.

By the end of September, the Lijiaxia Hydropower Station had generated a cumulative power generation of 142.482 billion kilowatt hours.
