JSC Electric Power Plants (EPP) has awarded a $104 million turnkey contract to a joint venture of GE Hydro (France) and GE Renewables (Switzerland) for modernization of the Toktogul hydropower plant in the Kyrgyz Republic.
The modernization project includes new state-of-the-art units which will improve safety, efficiency, reliability, and availability of the Toktogul project, located on the Naryn River in the Jalal-Abad Province and considered the country’s largest and most important hydropower plant, increasing its overall capacity to 1440 megawatts.
The Asian Development Bank (ADB) and the Eurasian Development Bank (EDB) financed the replacement of four units of the Toktogul, which has been generating about 6000GWh per year for 43 years. Because of aging equipment, however, the plant has experienced increasing number of failures in recent years.
“The phased rehabilitation of the Toktogul plant has been the key priority for ADB’s energy sector support in the Kyrgyz Republic and its timely rehabilitation is key to the country’s plan to export summer surplus to Afghanistan and Pakistan through the CASA-1000 power transmission line”, said Ashok Bhargava, Director for the Energy Division at ADB’s Central and West Asia Department.
EPP commenced phased rehabilitation of the Toktogul HPP project in 2012, starting with the refurbishment of the secondary electrical and mechanical equipment, the rehabilitation of two Toktogul units, and later completed by the remaining two Toktogul units, with an overall target completion by 2024-2026. The latest milestone was a result of the extensive competition among all major players and EPP’s innovative approach to procurement and design, which brought in competitive pricing and accelerated completion of the project by 3 years.
“In 2016, EPP decided to fast track the procurement of the four turbines and generators of the Toktogul HPP through single procurement for economies of scale, resulting to completion three years early. With ADB support, the EPP conducted multiple roadshows to improve the procurement design based on industry feedback and international best practice to increase completion for the project,” said EPP General Director Uzak Kydyrbaev.
GE Capital, the ultimate parent of the GE consortium, has provided a guarantee to support its operation in the Kyrgyz Republic. GE has committed to commission the first unit by November 2020, and one additional unit each year by November 2023.
