In Turkey, the 558MW Yusufeli Dam project in northern Artvin province was officially inaugurated in November by President Recep Tayyip Erdogan. The Yusufeli dam and hydroelectric power project


is located on the Çoruh River, upstream of the Borçka, Muratli, and the Deriner hydroelectric power plants. The project comprises a 275m tall double curvature concrete arch dam and a power plant equipped with three 186MW vertical-axis Francis turbine units. Each turbine unit is designed to operate at a rated head of 191m and a rated discharge of 107m3 The Yusufeli Dam created a 33.63km2


/sec. reservoir


area with a total storage capacity of approximately 2.2 billion cubic metres. The maximum crest elevation and the crest length of the dam are 715m and 490m respectively. The dam project also involves four balanced cantilever viaducts, including the 644m-long Tekkale viaduct, the 695m-long Yusufeli viaduct, the 340m-long Yusufeli dam viaduct, and the 530m-long Silenkar viaduct, along with the construction of 110km of roads, 45 tunnels, 22 bridges, and 92 culverts. The other components of the project include the main power transformers, a 380kV switchyard, along with measuring and protection equipment.


Projects in Pakistan The 800MW Mohmand dam project on the River Swat in


Pakistan’s Khyber Pakhtunkhwa Province is likely to be completed in 2026, the Water and Power Development (WAPDA) has announced, confirming that construction is underway on all 11 sites at the project. During a recent site visit, Chairman WAPDA Engineer Lt Gen Sajjad Ghani (Retd) was told that the diversion system is scheduled for completion in November this year, with the project looking likely to complete in 2026. The Chairman reviewed construction work on


different sites, which included the re-regulation pond, main dam, spillway, diversion tunnels, access tunnel, power intake, power house, switch yard and irrigation system etc. He was briefed that most of the damage caused to the diversion system during last summer’s flood were repaired by December. At present, the construction work is progressing ahead on all 11 sites of


the project, day and night on the sites where feasible. Mohmand Dam is a multi- purpose project which


will store 1.2 MAF of water and help mitigate floods in Peshawar, Charsadda and Nowshera. Besides supplementing 160,000 acres of existing land, it will also irrigate 18,237 acres of new land in Mohmand and Charsadda. Installed generation capacity of Mohmand Dam is 800MW. It will contribute 2.86 billion units of low-cost and environment friendly hydel electricity per annum to the National Grid. The project will also provide 300 million gallons water per day to Peshawar for drinking purpose. Estimated annual benefits of the Project stands at Rs. 51.6 billion. A sum of Rs. 4.5 billion has been earmarked for Confidence Building Measures (CBM) in the project area for socio- economic development of the locals. Another project for which construction is underway in earnest in Pakistan is the 4320MW Dasu hydropower project. The critical diversion system which forms a key part of the project in Pakistan is to be completed in May this year, with power generation expected at the project by the end of 2026, developer WAPDA has said. Dasu Hydropower Project is planned to be completed in two stages. At present, WAPDA is constructing stage-I with installed generation capacity of 2160MW and annual energy generation of 12 billion units of low-cost and environment-friendly electricity. Stage-II, once implemented, will also provide 9 billion units to the National Grid.


On completion of both stages, Dasu will produce 21 billion units on average. WAPDA is spending Rs. 17.34 billion on schemes relating to resettlement, environmental management and social development in the project area. About 3722 jobs, including 1945 for locals, have so far been created, which will increase to around 8000 during peak construction of the project. The project is being by WAPDA on River Indus


upstream of Dasu town in the Upper Kohistan district of Khyber Pakhtunkhwa province.


Milestone in Malaysia A key milestone for the 1285MW Baleh Hydroelectric


Project was achieved in September last year with the beginning of works for the Concrete Faced Rockfill Dam (CFRD). To date, the project’s construction has reached 33% completion. The commencement


f 2023 World Hydropower Congress to be held in Bali, Indonesia


The Government of the Republic of Indonesia will host the 2023 World Hydropower Congress alongside its electricity utility PLN and the International Hydropower Association (IHA) in Bali from 31 October to 3 November 2023. Announcing the Congress during his visit to Abu Dhabi for the IRENA Assembly, Minister of Energy and Mineral Resources, Arifin Tasrif


said: “To assure energy stability, security and growth in the long term, our challenge is to promote renewable energy and energy efficiency as critical tools. Indonesia has enormous potential to drive its industrial development through renewable energy sources, especially hydropower. We are therefore delighted to bring the world together at this year’s Congress.” The World Hydropower Congress will bring together decision-makers within and outside the hydropower industry to address how sustainable hydropower can help ensure energy security and reach global net zero emissions. The Congress is organised biennially by the IHA. This year it will have a principal theme of ‘Powering Sustainable Growth’. The Government of Indonesia’s hosting of the World Hydropower Congress follows their successful G20 Presidency during 2022. “Indonesia has demonstrated strong leadership and commitment to the sustainable energy transition, including plans to use its vast


potential of hydropower and other renewables to drive its economic development,” said Eddie Rich, IHA CEO. “Its Energy Sector Roadmap to Net Zero Emissions is perfectly aligned with the Congress’s theme of Powering Sustainable Growth. I’d like to thank the Indonesian Government and PLN in advance for their hospitality and their support for this event.”
