Huaneng Power International, one of China's largest listed power producers, has completed a 168-hour trial run of its 600MW ultra-supercritical coal-fired generating unit three at the Huaneng Yingkou power plant, which is located in Yingkou city in the Liaoning province of China.
Unit three at the Yingkou power plant is the first domestically made ultra-supercritical coal-fired generating unit that has a generating capacity of 600MW. The smooth operation of unit three marked China’s progression to a new stage in the design, manufacturing, installation and testing of 600MW generating units.
To date, Huaneng Power International, which constructs, operates and manages large-scale power plants across China, has seen total generation capacity on an equity basis increase from 28,187MW to 28,787MW.
The company wholly owns 17 operating power plants and has controlling interests in 12 operating power companies, as well as minority interests in five operating power companies.
