  • Data Highlight: Hydropower Continues Steady Growth

    World hydroelectric power generation has risen steadily by an average 3 percent annually since 1965. In 2011, at 3,500 billion kilowatt-hours, hydroelectricity accounted for roughly 16 percent of global electricity generation, almost all produced by the world’s 45,000-plus large dams. Graph ...

  • Africa’s hydropower future

    From Côte d’Ivoire in the west to Ethiopia in the east, Africa is home to some of the world’s fastest growing economies. Debates often proclaim a new era of economic boom, innovation and social opportunity for the continent. But beyond the hype, millions of people remain affected by severe poverty, and at the root of this lies a perennial problem: energy poverty. Could ...

  • Energy recovery in the water industry using micro-hydropower: an opportunity to improve sustainability

    The water industry as a whole consumes a considerable amount of energy in the treatment and distribution of water and wastewater. Like all sectors of society today, the industry is focusing efforts on reducing its CO2 emissions and improving the sustainability of its systems and practices. One way of achieving this is through the use of micro-hydropower (MHP) installations in water ...

  • Modeling future changes in the North-Estonian hydropower production by using SWAT

    Climate change is altering temperature, precipitation, and other climatic parameters, affecting sectors dependent on water resources, e.g. energy production. The purpose of this study is to analyze the possible influences of climate change on hydropower potential in North Estonia. In Estonian run-of-river hydropower plants, energy comes mainly from water volume. Thus, changes in hydropower ...

  • Evaluation of precipitation forecasts from NOAA global forecast system in hydropower operation

    Forecasts of 10-day average inflow into the Ertan hydropower station of the Yalong river basin are needed for seasonal hydropower operation. Medium-range inflow forecasts have usually been obtained by Auto-Regressive-Moving-Average (ARMA) models, which do not utilize any precipitation forecasts. This paper presents a simple GFS-QPFs-based rainfall - runoff model (GRR) using the 10-day accumulated ...

  • Energy recovery potential using micro hydropower in water supply networks in the UK and Ireland

    The supply and treatment of water is a highly energy intensive process, resulting in large amounts of greenhouse gas emissions as well as incurring large economic costs. Both governments and water service providers worldwide recognise the need for more sustainable water supply systems. In recent years, the use of hydropower turbines within water supply networks has been shown as a viable option ...

  • A non-linear rainfall-runoff model applied to Amazon small catchments with limited data to simulate the flow duration curves

    In Amazon, hydroelectric power production excludes ungauged small catchments. Thus, the main objective of this paper is the implementation of a non-linear rainfall-runoff model on small catchments in the Amazon region to simulate flow duration curves for the hydropower production. Because the rainfall-runoff process is non-linear, modification is applied to a simple linear model based on the ...

  • SHP stations and integrated rural development: a multivariate statistical approach

    The multi-functional role of the rural space is gradually being enhanced in recent decades, as agriculture seems to be losing its leading position. The diversification of local economies through the exploitation of natural resources is being highlighted as a fundamental driving force for development. Renewable Energy Resources (RES) and, more specifically, the establishment of Small Hydropower ...

  • A Bayesian approach to probabilistic streamflow forecasts

    One-month-ahead streamflow forecasting is important for water utilities to manage water resources such as irrigation water usage and hydropower generation. While deterministic streamflow forecasts have been utilized extensively in research and practice, ensemble streamflow forecasts and probabilistic information are gaining more attention. This study aims to examine a multivariate linear ...

  • Integrating water resources management in eco-hydrological modelling

    In this paper the integration of water resources management with regard to reservoir management in an eco-hydrological model is described. The model was designed to simulate different reservoir management options, such as optimized hydropower production, irrigation intake from the reservoir or optimized provisioning downstream. The integrated model can be used to investigate the impacts of ...

  • Chile Renewables Report Q1 2013

    We have downgraded our non-hydropower renewable generation growth forecast for 2013 from 6.2% to 5.6% due to new data from the government. Conversely, we have revised up our long-term growth forecast from 5.5% to 6.3%, due to our expectations of economic growth and the country’s current power situation. That said, we note that economic viability could be lacking in many renewable energy ...


  • Developing reservoir operational decision rule by genetic programming

    The reservoir operational decision rule is an equation that can balance reservoir system parameters in each period by considering previous experiences of the system. That equation includes variables such as inflow, volume storage and released water from the reservoir that are commonly related to each other by some constant coefficients in predefined linear and nonlinear patterns. Although ...

  • Stochastic simulation of daily streamflow sequences using a hidden Markov model

    Estimation of daily streamflow time series is of paramount importance for the design and implementation of river engineering and management projects (e.g., restoration, sediment-transport modelling, hydropower). Traditionally, indirect approaches combining stochastic simulation of rainfall with hydrological rainfall–runoff models are used. However, these are limited by uncertainties in model ...

  • Renewable energy and energy efficiency in Bulgaria

    The interest in renewable energy sources (RESs) utilisation and energy efficiency improvement programmes in Bulgaria reflects the changes in the field of energy policy worldwide and in Europe. Now energy management becomes a great problem of inner policy of Bulgarian government. In the last few years there has been a growing attention to the RESs applications. Bulgaria has one of Southern ...

  • Mount Kenya biosphere reserve

    Mount Kenya rises to 5199 m. a.s.l. and thus a major landmark. The mountain is a Pleistocene composite dormant volcano. It is a major water-tower that serves lowland inhabitants up to the Indian Ocean. It was protected as National Park in 1949 and in 1978, its summit and the Park became a BR and a World Heritage Site in 1999. Its main virtues include a rich biodiversity and the only glacial ...

  • Renewables account for 11%+ of U.S. electricity production

    Renewable energy, including wind, solar, biomass, biofuel, geothermal, and hydroelectric sources, accounted for 11.14% of U.S. electricity production during the first six months of 2010, according to the most recent issue of Monthly Energy Review by the U.S. Energy Information Administration (EIA). The 11.14% figure marks continued growth for U.S. renewable energy, which accounted for 10.71% of ...

  • Impacts of Danjiangkou reservoir on sediment regime of the Hanjiang River

    With population increase and economic growth, the development of water resources and hydropower resources of the Hanjiang River has been intensified by dam building, and consequently the sediment regime of the Hanjiang River has been altered to some extent. To assess dam-induced alterations in the sediment regime of the Hanjiang River quantitatively, we selected three key hydrological stations ...
