The world faces a fundamental challenge: meet the growing global demand for affordable electricity to power economies and eradicate poverty, while drastically reducing carbon emissions and safeguarding the world’s rivers, wetlands and forests and the communities that depend on them. The reality of climate change demands the world to transition to a more sustainable energy future.
Hydropower is a key low-carbon option, but its use has often been linked to high social and environmental impacts —such as the displacement of communities and the loss of many of the world’s rivers and their diverse ecosystems and benefits. Hydropower development faces the challenge to propose credible alternatives to diminish the need for such high-impact dams.
A basin-level or system-scale approach to hydropower development is required to ensure sustainable results of hydropower projects across the world. Landscape planning approaches, integrating environmental demands and other uses and users, can sustain ecosystem services and offer the potential for broad economic benefits in addition to energy generation, such as water supply, flood-risk management, irrigation, and habitat for migratory fish and biodiversity. Additionally, it provides a platform to better engage projects with stakeholders, and other projects operating in the same basin. To support a system-scale approach, basin-level water resources assessments are needed, accounting for these possible benefits.
FutureWater applies a state-of-the-art toolset, including tools that are being developed in-house, to a wide range of sustainable hydropower projects. Depending on the context and issues of concern, a tool and data sources are selected, including remote sensing datasets on glacier extent for high mountain areas, reanalysis datasets for a consistent global climate data, and hydrological models.
For example, for small hydropower run-of-river projects in high mountain areas, typically the glacio-hydrological model SPHY is applied to assess flow duration curves and floods extremes. The same model, in combination with climate model ensemble outputs, can be used to assess climate risks, climate change impacts and to evaluate the scope for increasing climate resilience to hydropower assets.
For basin-level and landscape-planning approaches, FutureWater has extensive experience with assessing the potential for Sustainable Land Management activities in a catchment, its costs and benefits, its impact on hydropower generation and demands and supplies of other uses and users and environmental flows. To support the dialogue with stakeholders and provide quantitative evidence on possible business cases for revenue sharing schemes, return-on-investment analysis can be performed and presented in ways that are digestible for a wide public.
Hydropower production in Indonesia is the main renewable energy source in the country. There is a potential to double the capacity by building new hydropower plants and to optimize current plants. PLN is the main hydropower company in the country. The project aims at enhancing the capacity of its staff…
The objective of this project was to develop a hydrological assessment for two potential hydropower plant locations in the Mestiachala basin in Georgia. The availability of observed river discharge data is limited. Hence the assessment was developed based on hydrological simulations of the basin using the SPHY model (Terink et…
This study assessed the impacts of various investment portfolios for catchment management activities on the cost-benefits of small hydropower schemes, in two case study catchments in Kenya and Tanzania, and analyzes the return-on-investment for the hydropower developers. Catchment degradation trends, climate change impacts and socio-economic changes increasing competing water use…
The novel methodology that is piloted by the World Bank for assessing climate risks versus other risks on water resource projects, called the Decision Tree Framework (DTF), is applied to two two planned investments: (1) flood protection infrastructure and irrigated cropland expansion on the Nzoia river, Kenya; and (2) the…
A hydrological assessment was carried out for two sites where run-of-river hydropower plants are planned, in the southwestern part of Georgia. Only very limited streamflow data were available, so the assessment was based mainly on hydrological modelling of the basin upstream of the points of interest. Principally global datasets were…
Following the successful development of hydropower facilities in Indonesia, a new project was established to study the potentials for the development of a hydro-electric power plant in the Tripa Basin, North Sumatra, Indonesia. To make a go/no-go decision of a more detailed feasibility study, a pre-feasibility study is undertaken to…
The overall objective of this project is to improve the understanding of the expected impacts of climate change on water availability in the context of potential hydropower development in the Tamakoshi River Basin. Specifically, the project aims to (i) Understand the current baseline hydrological regime of the Tamakoshi River Basin,…
FutureWater provided a comprehensive review study on climate change and the impacts on cryosphere, hydrological regimes and glacier lakes in the Indus, Ganges, and Brahmaputra river basins. This review study was done in the context of future hydropower development in the region.
The objective of this study was to support the “Central Asia Regional Energy Sector Vulnerability Study” led by Industrial Economics (IEc) and funded by the World Bank, by carrying out an expanded risk assessment for water availability and water related energy sector impacts in Central Asia. The work built on…
