The first unit of the Suki Kinari Hydropower Project in northwest Pakistan was successfully connected to the national grid on Monday, marking a significant milestone in the China-Pakistan Economic Corridor (CPEC) initiative.

The project, located in the Mansehra district of Khyber Pakhtunkhwa province, is being developed by China Energy Construction Overseas Investment Company Ltd. Once fully operational, the 884MW plant will generate approximately 3.21 billion kilowatt-hours of electricity annually, supplying affordable clean energy to over 1 million households.

Suki Kinari is expected to play a key role in addressing Pakistan’s electricity shortfall, reducing coal consumption, and lowering carbon dioxide emissions by an estimated 2.52 million tons per year. Construction began in January 2017, and the facility is scheduled to become fully operational later this year.

At the heart of the Suki Kinari project are four Pelton turbine generators, each with a capacity of 221MW, collectively contributing to the total capacity of 884MW. The hydropower plant boasts a maximum net head of 922.72m and a minimum head of 845.76m.

The reservoir’s operating parameters are set with a maximum level of 2233m and a minimum level of 2223m, holding a storage capacity of 10.37 million m3 below the minimum operating level. The project also features an underground powerhouse located approximately 400m deep and a tailrace tunnel extending about 1583m.

CPEC, launched in 2013 as part of China’s Belt and Road Initiative, focuses on enhancing energy, transportation, and industrial infrastructure in Pakistan. The successful connection of the Suki Kinari project’s first unit to the grid is seen as a critical step toward its commercial operation.
