  • 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 ...

  • Small hydro projects – renewable or ruinous?

    With thousands of rivers and streams running through British Columbia, small hydro energy projects seem like a significant source of renewable energy. Although such projects have low environmental impacts compared to major hydro-electric dams, they face a significant level of opposition from the public. ...

  • Implementation of a small hydro power project in India: issues and lessons

    In this paper, we present a longitudinal case study of a power sector start-up in India. Using the case as a starting point, we carefully analyse and explore the opportunities and challenges of implementing a small hydro power project in India. Using this case study, we identify the key success factors for a company to succeed in this sector. Based on first-hand observation of the progress of ...

  • Control of dynamic effects in small hydro with long hydraulic circuits

    Lab tests in a long hydraulic circuit were developed to analyse hydrotransients induced by waterhammer effects under runaway conditions. The definition of suitable design criteria in hydraulic systems is of utmost importance and has become a priority for good design implementation. The dynamic behaviour of turbo-generators of small reaction turbines and the interaction with long hydraulic ...

  • 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 ...

  • Hydro energy: techno-economic and social aspects within new climate regime

    Small hydro systems can provide electricity for: central-grid, isolated-grids, and/or remote power supplies. Small hydraulic power also provides an extra contribution to national electrical production in the case of consumption peaks. Although hydro is currently the second most used renewable energy source in the world, still there is a significant unexploited potential. The clean development ...

  • Techno-economics of micro-hydro power plants for remote villages in Uttaranchal in India

    Results of a techno-economic feasibility evaluation of some micro-hydro power (MHP) plants being planned and implemented for remote village power supply in the state of Uttaranchal in India are presented. The capital cost of MHP plants in the capacity range of 20–100 kW (including cost of local transmission and distribution system), investment requirement per unit of rated capacity, and relative ...

  • 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 ...

  • Micro and Mini Hydro Technologies-Vulnerabilities and Adaptation to Climate Change

    Micro hydro is one of the most mature decentralised energy technologies used in developing countries like Nepal. Micro hydro as “social infrastructure” supports in development of isolated off-grid electricity through community participation, which increases the capacity of rural communities to understand the dynamics of rural development and needs of social cohesion for expected ...

  • Hydro Nano Gas could be the Answer for Neutralizing Carbon Fuel Emissions

    Hydro Infra Technologies (HIT), a Swedish clean tech company based in Stockholm, has developed an innovative patent pending approach for neutralizing carbon fuel emissions by generating a novel gas called Hydro Nano Gas (HNG). In spite of all the advancement happening in the energy sector, globa economies are ...

  • Grid Connection An open letter to those on grid considering pursuing hydro power

    Many people contact us concerning the possibility of using a power source that is either connected to the commercial power grid or feeding power to a house that is. While this may be possible, it is not likely to make economic sense. Over 99% of our customers are off-grid and there are reasons for this. The question is then more like: ’Can I put in a small hydro system or should I spend ...

  • 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 ...

  • Small hydropower projects and sustainable energy development in Sri Lanka

    Sustainable development has evolved to encompass three major viewpoints: economic, social and environmental. Given the wide-ranging potential impacts of energy on national sustainable development, we review the linkages between these two topics. In the Sri Lanka case study presented here, the Sustainomics framework is used to assess the role of small hydroelectric power projects in sustainable ...

  • Hydro-geochemical characteristics of groundwater of Sirhind Nala sub-basin (Ghaggar river basin, India) in relation to salinity hazard

    Hydro-geochemical investigation of groundwater of Sirhind Nala sub-basin of the Ghaggar river basin (Southwest Punjab) has been carried out to study the distribution and sources of various dissolved ions. The levels of EC indicated that high salinity of groundwater was confined to small patches. The variations in EC levels seem to be related to non-flushing of water entrapped by clay beds, ...

  • Multicriteria decision analysis for the selection of a small drinking water treatment system

    The selection of a small drinking water treatment system for a hydro-electrical plant is addressed within a multicriteria and participatory decision analysis process. As a first step, based on problem constraints, we identified and retained three water treatment systems alternatives. In close collaboration with the stakeholders, we then defined and obtained weights for criteria that take into ...
