SK Hydro also known as Suki Kinari Hydropower Plant, is an under construction, run-of-the-river hydropower project located on the Kunhar river in the Kaghan valley of Mansehra District, Khyber Pakhtunkhwa, which has an installed generation capacity of 870 MW.

The project was first envisaged in 1960, and feasibility studies have been carried out by German GTZ, Quebec based Montreal Engineering and recent detailed design and engineering study was performed by Mott Macdonald of UK.

Khyber Pakhtunkhwa, M/s Al-Jomaih Holding Company, (LLC) (Saudi Arabia), China Gezhouba Group Company (China) and Haseeb Khan (Pvt) Ltd. (Pakistan) are sponsors of the project. “Suki Kinari project is being developed with an investment outlay of US$ 1,800 million through debt equity ratio of 75:25 percent. The lenders for the project include Export-Import Bank of China, and Industrial and Commercial Bank of China (ICBC).”

due to lack of stupid leadership and shortsighted people we have destroyed our future time to wake up from sleep and do what is good for us and our futre we have to live in pakistan these all leaders MNA and MPA will run away in tough times to nation time to stop supporting blindly we are the ones who are responsible for such stupidity and menace situation

jin ki waja se hum marein acha hai wohi mar jain message to stupid leaders

China has successfully inserted a 120-meter straw, more commonly known as steel pipe, into the Himalayas to control silt deposit, enabling increase of power generation capacity in Tarbela dam.

The silt at the bottom of the hydropower station was an impediment that needed to be removed before expansion the dam that was announced in 2013. To combat the issue, Chinese engineers decided made use of airlift for silt removal by inserting a 120 meters’ long pipe, the largest in the world, into the bottom of the hydropower station. The due process took four months to remove about 14,000 cubic meters of sludge.

In 2013, Pakistan had decided to expand the Tarbela Hydropower Station under Chinese assistance as per the initiates of BRI. Tarbela hydropower station is located in the fault zone of the Himalayas, which greatly increases the difficulty of the extension project due to a large inflow of sediments. However, the newly-inserted steel pipe helps to airlift the sediments, increasing approximately 1.41 million kilowatts of electricity subsequently.

The Tarbela 4th extension hydropower station is currently the largest power supply base in Pakistan, with an average annual power generation of 11.5 billion kWh, quoted Chinese media on Monday in local paper.

It also quoted that despite Chinese Three Gorges Dam being the largest hydropower station in the world and the largest hydropower construction project ever undertaken in China, its annual power generation is about 100 billion kWh, amounting to 20% of the national hydropower generation. However, Chinese engineers did not face such an issue with these dams relating to removal of soil or sediment at large.

Regarding the matter, Pakistan Minister for Water Resources Makhdoom Khusro Bakhtiar told Senate earlier that the total sediments deposited in Tarbela reservoir from 1974 to 2017 amount to 4.731 Million Acre Feet (MAF).

Second unit of Tarbela 4th Extension resumes power generation

LAHORE: The second unit of Tarbela 4th Extension Hydropower Project resumed its operation on Friday after engineers removed the fault with its draft tube gates.

Last week, the first unit of the project was put back into power generation after the engineers lifted the draft tube gates that were stuck when silt was piled up because of unprecedented slide of water levels to the dead level and issues with valves on the penstock.

According to an official, the project is required to undergo testing for another 570 days of defect liability period (DLP) with total responsibility of the contractor for its repair, maintenance and replacement. “Tarbela produces more than 3,400MW energy through its 14 units commissioned on its first three tunnels. The project of three units of 470MW each was planned in 2012-13 on 4th tunnel called Tarbela 4th Extension to add 1,410MW to the national grid. A coordinated construction schedule was planned to make full use of flood season of 2018. The first unit was inaugurated on March 10, 2018,” explained a source.

He said that taking full consideration of hydrological data of the last 10 years, the wet commissioning of the first unit was carried out between Feb 20 and March 10. Wet commissioning is about uninterrupted tests, including mechanical speed, balancing of generator and load rejections. Fortunately, there were sufficient water levels and during wet commissioning, the unit remained at different loads till maximum load of 303MW as per water head.

Unprecedented changes in hydrological behaviour, climate change and huge deposits of silt in Tarbela led to lower water levels. Later, the unit was completely flushed, cleaned and shut down on March 11. However, sequel to water levels raise in June, the unit restarted and ran optimally without any trouble, producing 173 million units till July 5.

The official said that following another unprecedented slide of water below the dead level, the unit was again shut down.

He said the movement of pivot of silt delta and a crack in one of the valves (purely a technical issue) led to jamming of draft tube gates. The project is now under testing and the defect liability period. Valves have been replaced. Both the stuck gates had been raised without compromising technical regimes, he added.

A press release issued by a spokesperson for Wapda says that first and second units are adding 300MW and 470MW to the national grid.

“The third unit of the project is also complete and expected to start power generation by the end of this month,” it adds.
