  • Health and environmental impacts of the hydroelectric fuel cycle

    The impacts on health and the environment and the associated damage costs caused by the hydroelectric fuel cycle are assessed in this paper. To this purpose, a large hydroelectric project along the Nestos river in northern Greece has been selected as an example. A large number of impacts have been identified. Occupational accidents, impacts on agriculture and forests, noise produced during the ...

  • 1997 IFAI award devil Canyon hydroelectric power plant, San Bernardino, California - Case Study

    Constant demands for water and electricity in heavily populated areas in California prompted the Devil Canyon Power Plant project. Constructed from 1969 to 1974, the power plant is located at the San Bernardino Mountains near the mouth of Devil Canyon. With two pipelines carrying water from Silverwood Lake, an elevation drop of almost 1500 ft (460 m) between the lake, and four Pelton wheel ...

  • Economic analysis of the environmental and social impacts of the Nam Theun 2 Hydroelectricity Power Project

    The Nam Theun 2 Hydroelectricity Power Project (NT2), located in the Khammouane Province of central Lao's People Democratic Republic (Lao PDR), aims to produce electricity with a generating capacity of 1,070 MW. Most of the electricity generated (995 MW) will be sold to the Electricity Generating Authority of Thailand (EGAT) and the remaining (75 MW) sold to Electricite du Laos (EDL). The primary ...

  • Continuous Quality Surveillance Scheme to minimize the Cost Of Poor Quality in the construction of hydroelectric powerplants - IDRA 2012

    During the construction of hydroelectric plants, poor quality can have a hugely negative impact on construction time, on plant performance and on safety. We propose a method of keeping under control the manufacturing of the most critical components, such as pressure parts, rotors and valves, with a view to minimizing the Cost of Poor Quality (COPQ). This method is known as the Continuous Quality ...

  • The ABCs of small hydro upgrade and automation

    Abstract - Small hydroelectric is increasingly depended on to provide regional power capacity, as municipalities seek more sustainable sources of energy. Yet, hydroelectric or hydro power has some negative perceptions. Other sustainable sources of energy like wind and solar power are early in their equipment and technology life cycles. Hydroelectric facilities are typically older and operate with ...

  • Risk sharing in hydropower development: case study of the Chukha Hydel Project in Bhutan

    The Himalayan rivers have an enormous hydropower potential that is still not exploited fully for the benefit of the region. Bhutan and Nepal together have an economically feasible potential of 60,000 MW of hydroelectric power generation capacity but are too weak financially to bear the risks associated with the development of their hydro resources alone. India is the only potential market for ...

  • 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 ...

  • A novel technique proposed for automatic control of small hydro power plants

    A new scheme is proposed for the speed control of hydro turbines. Power can be controlled by controlling the rotary motion of the spear valve or linear motion of the sluice gate. In this paper, necessity for speed control, various function of governors, types, speed regulation of micro-hydroelectric power plants, functional block diagram of power generation and control system general models for ...

  • A method for the study of cascading effects within lifeline networks

    The following research is in keeping with the current international and national trend to establish effective facility management plans, based on antagonistic notions of maximal production and minimal risks. The application of this approach to lifeline networks is complex, considering that the failure of these networks can cause extensive consequences for populations and upon socio-economic ...

  • 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 ...

  • No Place Is Too Far

    The remote location of hydropower stations is often a great challenge when major repair work is necessary. The refurbishment of a large generator in the Scottish Highlands shows how Sulzer finds cost-effective service solutions even in places miles from nowhere. Much of the UK hydroelectric capacity was built during the 1950s. These installations have performed extremely well, especially ...

  • Wind Energy Production Estimates: Moving Beyond Time Averages

    No need to be a statistician to see that averages are often useful to compare different things. And yet, they often fall short as a true measure of performance. For instance, we use averages to compare the current weather against the climate normals or to get a sense of how our favorite sport team or player is doing. Team (player) statistics are a concise way of combining the scores from many ...

  • How to make hydropower more environmentally friendly

    Hydropower provides 85 percent of the world’s renewable electricity, but comes with a hefty environmental price tag. Here’s what some are doing to fix that. Humanity got its first large-scale electricity thanks to hydropower. On Aug. 26, 1895, water flowing over Niagara Falls was diverted to spin two generators, producing electricity to manufacture aluminum and carborundum. Since ...

  • Implementation strategies and a cost/benefit comparison for compliance with an environmental flow regime in a Mediterranean river affected by hydropower

    Compliance with the Water Framework Directive (WFD) of the European Union requires water managers to establish environmental flow regimes (EFR) in rivers across the continent. Few water agencies have examined the economic and social welfare impacts of implementing environmental flow requirements. We present the approach used by the Catalan Water Agency to calculate an EFR and estimate the ...
