  • Rogun Hydropower Project, Tajikistan

    Huckbody Environmental has been commissioned by the World Bank to undertake an HSE due diligence analysis of the Rogun Hydropower project in Tajikistan. According to the current conceptual design Rogun would be a reservoir type HEPP with a dam height of about 335 m X ca.1500m at its base. The reservoir would have a total storage volume of 13.5 million cubic meteres and an active storage volume of ...

  • Factsheet: Hydropower and ecology

    Accounting for 20% (around 3,400 TWh) of global electricity production – even though its contribution to gross final energy consumption is only about 2% – hydropower plays a vital role. This is largely due to the fact that it can be readily regulated to meet fluctuations in demand and substantial reserves can be stored in reservoirs. Hydropower supplies around 56% of Switzerland's ...

  • Hyporheic water exchange in a large hydropower-regulated boreal river – directions and rates

    Widespread river regulation is known to modify river-aquifer interactions, influencing entire watersheds, but knowledge of the hyporheic flowpath along regulated rivers is limited. This study measured the hydraulic conductivity of the river bed and the aquifer, water levels and seepage fluxes in the heavily regulated Lule River in Northern Sweden, with the aim of characterising water exchange ...

  • Large-scale hydropower system optimization using dynamic programming and object-oriented programming: the case of the Northeast China Power Grid

    This paper examines long-term optimal operation using dynamic programming for a large hydropower system of 10 reservoirs in Northeast China. Besides considering flow and hydraulic head, the optimization explicitly includes time-varying electricity market prices to maximize benefit. Two techniques are used to reduce the ‘curse of dimensionality’ of dynamic programming with many ...

  • 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 ...

  • 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 ...

  • 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 ...

  • The potential impacts of climate change on hydropower generation in Mid Wales

    Hydropower is a potential large source of electricity supply in Wales. The Upper River Severn in Mid Wales is a typical stream where a high head hydropower scheme could be developed and the river system at Plynlimon has some of the longest records for weather and flow in Wales. A micro-hydropower potential of 99 kW is demonstrated at Plynlimon and the potential impacts of climate change are ...

  • Website offers global view of small hydroelectric projects

    It is now easier to access reliable data on small hydropower projects globally following the launch of a website designed to promote this technology, says a UN body. The UN Industrial Development Organization ...

  • Power from closing the Red Sea: economic and ecological costs and benefits following the isolation of the Red Sea

    The closure of the Red Sea at its southern entrance (the Bab-al-Mandab Strait) could well lead to the world's largest hydropower generation, in the order of 50 000 MW. The cost and time-scales involved are beyond normal economical considerations. Macro-engineering projects of this size cause a massive destruction of existing ecologies. On the positive side of the environmental scale, however, are ...

  • Long Tan Hydroelectric Dam

    Black & Veatch is the design and construction consultant for the world's largest roller-compacted concrete dam, which will be the world's fourth largest hydropower station and protect 12 million people from flooding. China must create urban infrastructure for the equivalent of the city of Houston, Texas, every month for the next 30 years to accommodate the relocation of 280 million rural ...

  • 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 ...

  • World Wind Power Poised to Bounce Back after Slowing in 2013

    At the end of 2013, the wind farms installed in more than 85 countries had a combined generating capacity of 318,000 megawatts, which would be enough to meet the residential electricity needs of the European Union’s 506 million people. New data from the Global Wind Energy Council show that wind developers built 35,000 megawatts of new generating capacity worldwide in 2013. This was down ...

  • Want a better way to power your car? It`s a breeze

    Legendary Texas oilman T. Boone Pickens is half right. We do need to harness this country's wind resources for a homegrown source of electricity, as he has been urging this summer in expensive television ads. And we do need to reduce the $700 billion we may soon be paying annually for imported oil. But part two of Pickens's plan--to move natural gas out of electricity production and use it to ...

  • As Global Demand for Electricity Grows, Geothermal Energy Heats Up

    January 9, 2017 — At 2:46 p.m. local time on Friday, March 11, 2011, Japan was rocked by the largest earthquake ever to strike its shores. The 9.1 magnitude quake triggered a devastating tsunami that killed more than 15,000 people. It also took out the back-up emergency generators that cooled the reactors at the Fukushima Daiichi nuclear power plant complex, causing a series of ...
