Hydropower represents an interesting technology: affordable, renewable, and flexible. However, it must cope with climate changes and new energy policies that jeopardize its future. A smooth transition to sustainability requires decision makers to assess the future perspectives of hydropower: about its future revenue and related uncertainty. This investigation requires a multidisciplinary approach as both streamflow and energy mix will evolve. We simulated future streamflow based on eight climate scenarios using a semi-distributed hydrological model for our case study, the Tremorgio hydropower plant located in southern Switzerland. Next, using a hydropower management model we generated income according to these streamflows and twenty-eight electricity price scenarios. Our results indicate that climate change will modify the seasonality of inflows and volumes exploitable for hydropower generation. However, adaptive strategies in the management of reservoirs could minimize revenue losses/maximize revenue gains. In addition, most market scenarios project an increase in revenues, except in the case of high wind and solar energy penetration. Markets do not provide the right incentive, since the deployment of intermittent energy would benefit from more flexible hydropower.

Tajikistan has formulated the strategy to rejuvenate the country through hydropower. The Rogun hydropower plant (HPP) is designed as the highest hydropower station, while its sustainability is also questioned due to a lack of comprehensive sustainability evaluation. Considering that the external environment of Rogun HPP is complex and changeable, its sustainable performance will be fragile and inconstant. To comprehensively assess the sustainable performance, an integrated evaluation framework, covering the current and dynamic sustainable performance, is urgently established. Therefore, this paper firstly explored the hydropower sustainability assessment indicators which can conform to Tajikistan’s situations and further examined the current sustainable performance of Rogun HPP. The case study found that Rogun HPP’s current financial viability, involuntary resettlement, the measures to prevent corruption, and information disclosure were seriously deficient. The SWOT analysis indicated the external factors, such as the Belt and Road Initiative, improving business environment, and easing geopolitical disputes, can eliminate weaknesses and improve the sustainable performance of Rogun HPP. At the same time, tight fiscal allocations and economic downturns will have negative influences on the sustainable performance. The integrated evaluation tool established in this paper can not only evaluate the current sustainable performance but also consider the impact of external factors on sustainable performance from a dynamic perspective. This paper contributes to the current knowledge system by establishing the hydropower sustainability assessment system which is suitable for Tajikistan’s conditions. Moreover, the results are informative for the decision-makers to have a better understanding of Rogun HPP’s current strengths and weaknesses, valuable opportunities, and potential threats.
