  • West charleston hydro - Case study

    In 2004, Great Bay Hydro Corporation acquired four generating facilities in Vermont, including the West Charleston Hydro plant which had been out of operation and abandoned for a number of years. The West Charleston plant was built in the early 1900s and is located on the Clyde River in the town of Charleston, Vermont. In 2010, as part of the re-permitting process and in order to meet current ...

  • Namewaminikan hydro development - Case study

The Namewaminikan hydro project was optimized to reduce ...

  • Lockhart minimum flow - Case study

    Lockhart Power is the owner and operator of a number of hydro projects located in South Carolina. In 2011, CHC provided two water-to-wire packages for two new Lockhart hydro sites: a 1250 mm vertical axial flow Propeller minimum flow unit with generator and controls for the Lockhart Minimum Flow project and a 1700 mm axial flow Kaplan turbine with generator and controls for the Upper Pacolet ...

  • 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, ...

  • Minimum Flow Units - Case Study

    Environmental regulations are becoming more stringent and the minimum by-pass flow requirements are generally increasing in North-America. Many of our small hydro technologies are perfectly suited for this type of application whether it is to replace an existing pressure reducing valve or implement a new turbine upstream of the by-passed reach of an existing hydro plant. Shown below is an example ...

  • Research on joint generation scheduling of cascade hydro plants in the dry season

    As more and more reservoirs are built, concentrated water releasing in the dry season will bring about additional flow compensation and the joint operation of cascade hydro plants is quite important. This paper discusses the water level decline strategy of four cascade hydro plants in the Jinsha River and analyses the relationship between guaranteed output and total power generation. ...

  • Pumped hydro storage softens blow of wind imbalance penalties

    Quarry Battery is developer of the £160 million ($249.2 million) Glyn Rhonwy pumped hydro facility in Wales which will be the UK’s first grid-scale electricity storage facility for decades. The facility will produce nearly 50 MW of electricity using pumped hydro technology. As more fossil fuel-fired generation is taken offline and wind capacity grows, grid operators will ask wind ...

  • Canada’s Other Energy Boom – Energy infrastructure is on the move.

    When it comes to energy infrastructure, Canada is on the move. Of course, that may seem like nothing new, given Canada’s lengthy energy history, particularly in the oil and gas industries. In this latest chapter, however, electricity is playing a major role. A confluence of factors have helped spur the need for more generation, which in turn is driving still another form of energy ...

  • Generating Ecological Gains from Hydro-Electric Power - Case Study

    NCC has worked with Eskom to mitigate the environmental impacts of the Ingula Pumped Storage Scheme on a sensitive wetland site in the Little Drakensberg/Escarpment, including creating and managing a new conservation area. South Africa’s energy demand is growing at rates of around 5% a year, placing enormous pressure on Eskom not only to create new generating capacity, but also to manage ...

  • Negative Power Generation Aspects of Adopting Renewable Sources

    Renewable energy resources are all the rage nowadays on a global scale with the biggest benefit of providing unlimited access without any fear of depletion or running out in the near future. It also provides the edge of saving the continuously decreasing fossil fuel reserves and to protect the planet against the harmful pollution caused by the burning of all non-renewable resources. Some common ...

  • Saving Renewable Energy for a Rainy Day

    Despite advances in renewable energy technologies, one of the largest hurdles in their widespread adoption has been their intermittent reliability. Energy is only useful if it is available as the grid demands it, which is why concerns about carbon emissions are overridden in favor of the more dependable oil, coal and gas for baseload power. In order for renewable sources such as wind and solar ...
