Unit 3 of the Inner Mongolia Huineng Changchuan power project, a key national project under China's 14th Five-Year Plan (2021-25), has been connected to the power grid in Ordos city, Inner Mongolia, with all operating parameters performing steadily.

The unit completed its first grid connection just 20 months after construction began in March 2024 – nearly six months ahead of the standard schedule for coal-fired power projects – setting a new benchmark for safe, high-quality, and efficient construction.

With a total investment of 5.44 billion yuan ($777.14 million), the project comprises two 660 MW ultra-supercritical coal-fired indirect air-cooling units, equipped with flue gas desulfurization and denitrification systems and connected to the West Inner Mongolia Power Grid via 500 kV transmission lines.

Unit 3 features a 20 percent deep peak-shaving capability, enhancing the grid's ability to absorb renewable energy. By adopting an integrated coal-power model with on-site coal conversion, the project reduces coal transport pressure and related pollution, promoting cleaner, more efficient resource use.

Once fully operational, the project is expected to generate 7.2 billion kWh of electricity annually, with an annual output value of about 2.38 billion yuan, tax contributions of 420 million yuan, and nearly 1,000 jobs.

It serves as a key supporting power source for the "West Inner Mongolia–Tianjin South" ultra-high-voltage transmission corridor under China's west-to-east power transmission program, and as a major energy project underpinning high-quality development in the Yellow River Basin.
