  • Intro to Hydropower Part:2 Measuring head & flow

    Measuring the stream course—Anna and Joe work downstream, shooting vertical drop (head) with a sight level, and getting a rough measurement of the pipe run at the same time. Small-scale hydro is the only renewable energy source that works for you 24 hours a day, 7 days a week. In the first article in this series (HP103), I explained the basics of hydroelectric system theory, and ...

  • Control systems for small hydropower plants: a review

    Hydropower is emerging as a major contributor to world energy requirement. It is inexhaustible, clean and has many other benefits like flood mitigation, water supply, irrigation, etc. However, large-scale hydropower generation suffers from inherent disadvantages, such as massive financial outlays, long gestation periods, geological surprises, environmental factors and rehabilitation of the ...

  • 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 ...

  • 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 ...

  • Full-energy-chain greenhouse-gas emissions: a comparison between nuclear power, hydropower, solar power and wind power

    Fair comparison of the climate impacts from different energy sources can be made only by accounting for the emissions of all relevant greenhouse gases (GHGs) from the full energy chain (FENCH) of the energy sources. FENCH-GHG emission factors of most of the non-fossil fuel energies are lower than those of the fossil fuels that are in the range of 500-1200 g CO2/kW h(e). The improvement ...

  • Assessing the viability of microhydropower generation from the stormwater flow of the detention outlet in an urban area

    Small-scale hydropower is the generation of electrical power of 10 MW or less from the transformation of kinetic energy in flowing water to mechanical energy in a rotating turbine to electrical energy in a generator. The technology is especially useful when installed with a stormwater infrastructure in countries teeming with abundant rainfall. It is upon this concept that this study is being ...

  • Control of dynamic effects in small hydro with long hydraulic circuits

    Lab tests in a long hydraulic circuit were developed to analyse hydrotransients induced by waterhammer effects under runaway conditions. The definition of suitable design criteria in hydraulic systems is of utmost importance and has become a priority for good design implementation. The dynamic behaviour of turbo-generators of small reaction turbines and the interaction with long hydraulic ...

  • Discharge Measurement in a Short Intake with a Converging Section – a Case Study

    In the context of a planned retrofit and upgrade of the hydropower plant Wettingen, operated by the Elektrizitätswerke Zürich, three intakes were equipped with acoustic transit time flow measuring devices. Since the flow meters are installed in a converging section, downstream of a pier, it became necessary to perform numerical flow simulations in order to weight the acoustic path ...

  • New Italian norms to regulate the non-destructive inspections in the manufacturing and in the maintenance of parts of hydraulic machinery

    Introduction This paper presents two proposals of norms (standards) which have been discussed by a Working Group of UNI (Ente Italiano di UNIficazione, Italian expression of ISO) during 1998-2000, and will be soon submitted to examination by the technical verification commission of UNI. These proposals aim to provide procedures to perform and evaluate inspections on parts of hydraulic machinery ...

  • 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 ...


  • Oil and water don`t mix

    Small spots of motor oil on your driveway look tacky enough. Leaks of hydraulic oil from the hydro turbine of a big pumped-storage plant are not only more noticeable, but they also could end up in the facility's sump or in its reservoir, as well. At the Blenheim-Gilboa Pumped Storage Power Project in New York's Catskill Mountains, there's another reason leaks are unacceptable. The New York Power ...

  • Water sustainability decision-making for electric utilities case study

    The electric power generation sector uses approximately 41% of all freshwater withdrawn in the United States—more than any other water use sector. The Electric Power Research Institute (EPRI) conducts research and development to help address challenges in electricity generation, delivery, and use, including water sustainability issues. On behalf of EPRI, LimnoTech conducted research and is ...

  • Renewable Energy to secure our future

    Clean energy is being talked about these years. From private blogs to various commercials, posters and mailings, people everywhere seem to be concerned about it. Even President Obama attached greater importance to a sustainable development than his predecessors. However, clean energy can refer to several subjects. What is clean energy referring to? How does clean energy benefit you? Does clean ...
