  • Powering Renewable Programs: The Utility Perspective

    When considering how to build out a renewable energy portfolio, there are a lot of factors and many points of view to consider. For purposes of this narrative, we will take the point of view of the electric utility itself. Your electricity providers are quite familiar with the concept of a “smart grid.” According to the Department of Energy (DOE), a smart grid “generally refers ...

  • Application of the Most Recent Monitoring Systems in Hydro Power Plants

    Abstract The paper describes main reasons for refurbishment of hydro power plants and summarizes the most frequent works during refurbishment. A special attention is paid to the process of refurbishment of the electric equipment, in the first line generators and excitation systems, and integration of the most contemporary monitoring system. The paper talks about some of the methods of ...

  • 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 ...

  • Integration of pump storage hydro with wind energy

    Renewable energy has significant advantages as it does not contribute to Greenhouse Gases (GHG). Wind energy is a renewable energy alternative that is being installed worldwide. However, wind energy is unpredictable and thus, unavailable as compared to conventional generation. The availability of wind energy compared to conventional power plants is a cause of contention. Currently, the rate of ...

  • 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 ...

  • Hydro Polymers: Searching for a More Sustainable PVC

    Over the last five years, the European PVC industry has been forced to reassess the environmental impact of its products in the face of continuing pressure from environmental groups, governments and end users. Hydro Polymers, one of two PVC manufacturers in the UK, is forging ahead of its competitors through a partnership with sustainability consultancy The Natural Step. The company is launching ...

  • Case study - UV systems for spas & hydro pools

    With the rise of health centres and leisure clubs throughout the UK, a key feature in many modern facilities is the inclusion of spas and hydro pools.  As a specialist aquatic application, spas and hydro pools feature high turnover rates, high bather loads, increased turbulence and water temperatures above 35oC.  This combination of factors provides a perfect breeding ground for harmful ...

  • The Flakt-Hydro process: flue gas desulfurisation by use of seawater

    ABB's seawater scrubbing process (the Flakt-Hydro process) for flue gas desulfurisation has recently triggered much interest among power producers because of its simple operating principle and high reliability. The process uses seawater to absorb and neutralise sulfur dioxide in flue gases. The absorbed gas is oxidised and returned to the ocean in the form it originated in the first place, namely ...

  • Kelag demonstrates hydro power know-how in Bosnia-Herzegovina

    Austrian energy companies are increasingly helping to expand the hydro power capacities in the Balkans. On the River Ugar, which today marks the border between the Federation of Bosnia-Herzegovina and the Republic of Srpska, the Novakovici runof- river power plant has been delivered by a subsidiary of the Carinthian utility company Kelag, InterEnergo. In a normal year, the high-pressure plant, ...

  • Hydro-Transporting Food: best practices for food processing pumps

    Processing plants look for continuous and trouble-free operation from a pump capable of transporting even the most delicate whole food products or processed foods, while keeping product damage to a minimum. This ensures the highest profits for the plant. Cornell pumps help hydro-transfer systems to clean and convey potatoes, carrots, cranberries, pickles, cherries, beans, peppers, leafy ...

  • Manic 5 and Manic 5 PA (Hydro Québec), Quebec case study

    Part of an hydroelectric complex counting four dams, Manic 5 and Manis 5 PA are two power houses installed in the valley of the Manicouagan river, north of Québec. Unveiled in 1970, this plant represents the higher multiple-arch and buttress dam in the world. For the Manic 5 and Manic 5 PA sanitary water treatment, Hydro-Québec mandated the Groupe-conseil TDA to find a compact ...

  • Installing an ESD LH1000 A Micro hydro Evolution Article describing the installation of an ESD LH1000 low head machine

    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. ...

  • Short-term hydro thermal generation scheduling using modified invasive weed optimisation algorithm

    This paper presents a radical methodology to find the solution of optimal short-term hydrothermal generation scheduling problem using modified invasive weed optimisation algorithm (MIWOA). The hydrothermal system is highly non-linear and non-convex due to its constraints, making the optimal scheduling difficult. In this paper, a modified invasive weed optimisation algorithm with parallel ...
