China's Largest Overseas Greenfield Hydropower Project in Pakistan Starts Generating Electricity
TapTechNews August 12th news, China Energy Construction Group Co., Ltd. announced today that the largest overseas greenfield hydropower investment project of Chinese enterprises, the SK Hydropower Station in Pakistan, the first unit officially grid-connected and generated electricity on August 12 local time.
According to the introduction, the SK Hydropower Station is controlled and invested by China Energy Construction Overseas Investment Co., Ltd., participated in the investment by Gezhouba International Company, and constructed by Gezhouba Third Company and Gezhouba Electromechanical Company. The power station is located on the Kunhar River in Khyber Pakhtunkhwa Province, Pakistan. It is a diversion hydropower station with a long tunnel and extremely high head. The power station has a total investment of 1.962 billion US dollars, a head of more than 900 meters (about 2952.76 feet), 4 impulse turbines are installed in total, with a total installed capacity of 884 megawatts, and a total reservoir capacity of 13.45 million cubic meters.
The SK Hydropower Station has the largest impulse hydro-generating unit with the largest single capacity overseas and the world's deepest pressure shaft group. At the same time, the SK Hydropower Station is also the largest hydropower station invested and constructed by China Energy Construction overseas.
The first unit of the SK Hydropower Station completed the anhydrous commissioning test on May 25; the water commissioning test was completed on June 16; the overspeed test of the unit was completed on June 20; all electrical tests were completed on July 1, meeting the conditions for grid connection and power generation; the reverse power transmission test was completed on August 7, achieving one-time installation completion, one-time start-up success, one-time commissioning success, and one-time trial operation success for the first unit.
According to TapTechNews' inquiry, after the full commissioning and power generation of the project, it is expected that the annual power generation can reach 3.212 billion kWh, which can save about 1.28 million tons of standard coal and reduce about 3.2 million tons of carbon dioxide emissions every year, providing economical and affordable clean electric power for more than 1 million Pakistani households.
The SK Hydropower Station in Pakistan was o fficially approved and started construction on December 31, 2016, and it is expected to achieve full unit commissioning and power generation by the end of August 2024. During the construction process of the project, the constructors of China Energy Construction have created engineering miracles such as the world's deepest shaft group with the highest head under construction, with a downward excavation depth of more than 240 floors and a diameter of less than 6 meters (about 19.69 feet).
