Sustainable Electricity: One Step Closer to a Green Future
The continuous rise in carbon dioxide emissions for the last 30 years has led to increased atmospheric temperatures today. And the environment is getting more and more polluted due to the rapid industrialization and usage of fossil fuels for energy production. That is why there is a growing global demand for sustainable electricity, ensuring access to clean and affordable energy in order to stop ...

Enerdu plant expansion - Case study
Located in the picturesque town of Almonte, on the North bank of the Mississippi River, the Enerdu redevelopment project involves expanding the footprint of the original powerhouse out into the river to accommodate larger turbines and to increase the plant’s generating capacity by 70%. CHC provided a water-to-wire equipment package including two 2000 mm Axial Flow Kaplan pit units with two ...

Curtis hydro redevelopment - Case study
The Curtis Palmer hydro facility consists of two run-of-river hydroelectric generating stations located on the Hudson River, in Corynth, NY. In 2014, CHC provided two 2250 mm vertical axial flow Kaplan open flume turbines to replace two of the five horizontal units located in the Curtis powerhouse, which were running but in poor mechanical condition. The existing generators were removed, ...

Black river falls hydro - Case study
CHC provided a complete water-to-wire equipment package to the City of Black River Falls, Wisconsin, for the upgrade of its Black River Falls Hydroelectric Dam, located on the east bank of the Black River in Jackson County, Wisconsin. This historic dam rebuilding project was completed in June 2012, and involved the installation of an additional low-flow generating unit. The water-to-wire ...

Microhydro Evolution - Installation of a Low Head Hydro System
Every morning, before brushing teeth or having a look at the weather outside our Victoria, Australia, off-grid home, my wife Carrie or I pad downstairs to the battery room to check the meters that monitor our electrical system. The reading determines whether we use the propane stove or the electric jug to heat water for our tea. Since our microhydro plant upgrade, it’s usually the jug. ...

Framing the Brahmaputra River hydropower development: different concerns in riparian and international media reporting
Development of the Brahmaputra River, which links China, India and Bangladesh, has been hindered by significant challenges, particularly political challenges. News reports can mirror the perceptions of political actors, but are, owing to the complexity of the issue, complicated and unstructured. We present a comparative content analysis of the overall framing in news reports of the ...

Idaho Water District’s new Hydroelectric project - case study
This Irrigation District north of Twin Falls installed a new run of the river hydroelectric facility. In order to protect their new turbines, they installed this Traveling Water Screening System. The majority of debris consists of weeds, tumbleweeds, aquatic plants and urban debris. The 5 screens at this location drop debris on a 60’ long conveyor. The conveyor carries the debris to an ...

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 ...

Micro-Hydros Earn First Carbon Revenue in Nepal
MICRO-HYDROS EARN FIRST CARBON REVENUE IN NEPAL While the rugged mountains of rural Nepal don’t lend themselves to grid-fed electricity, their rivers, lakes, and glacial melt offer plenty of renewable resources for energy. Between 2007 and 2014, over 400 micro run-of-the-river hydropower plants were built by the Nepali government with help from the World Bank as part of the Nepal ...

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 ...

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 ...

Hydropower ambitions of South Asian nations and China: Ganges and Brahmaputra Rivers basins
This paper analyses the current status of hydropower development in two major rivers basins in South Asia, the Ganges and the Brahmaputra. The total drainage area of the basins is about 1,660,000 km² shared by China, Nepal, India, Bhutan and Bangladesh. These two basins are blessed with ample water resources and huge hydropower potential. The abundant hydropower potential of these rivers basins ...

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 rates ...
