Rehabilitating a hydropower plant in Tajikistan
Our investment in the rehabilitation of the Qairokkum hydropower plant in Tajikistan is an excellent example of how the EBRD can integrate climate resilience into an infrastructure investment.
In 2014 we launched one of our largest projects in Tajikistan’s energy sector to date, with a US$ 50 million (€41 million equivalent) loan to fund the modernisation of the Qairokkum hydropower plant. The first phase of the programme will consist of installing two new and larger turbines, which will increase the plant’s current capacity from 126 MW to 142 MW. This will prevent wasteful water spills and generate more electricity with the same flow of water, thereby maximising the plant’s efficiency. The investment will also finance the installation of modern equipment that will raise safety levels and strengthen the plant’s resilience against the impacts of climate change.
The project design was based on detailed climate change and hydrological models. Projections were made of the Syr Darya river basin’s future hydrological conditions, based on an analysis of 16 climate change models running nine different hydro-climatic scenarios and three greenhouse gas emission scenarios. The potential energy output of three different turbines was also modelled across the same range of scenarios. The turbine upgrade option showing the lowest maximum regret value was identified as the most climate-resilient option and used in the investment design. Climate change considerations were also used to inform dam safety upgrades.
