Review of small hydropower technology
Renewable and Sustainable Energy Reviews, 2013
This paper gives a review of small hydropower technology. A Small hydropower (SHP) plant uses impulse or reaction turbines and is mainly 'run-off-river'. SHP technologies currently used in generating electricity for rural electrification in both developed and underdeveloped countries are helping to slow down climatic change, creating employment opportunities, and are having low maintenance costs (but high capital costs).
Small hydro power: technology and current status
Hydropower, large and small, remains by far the most important of the "renewables" for electrical power production worldwide, providing 19% of the planet's electricity. Small-scale hydro is in most cases "run-of-river", with no dam or water storage, and is one of the most cost-effective and environmentally benign energy technologies to be considered both for rural electrification in less developed countries and further hydro developments in Europe. The European Commission have a target to increase small hydro capacity by 4500MW (50%) by the year 2010. The UK has 100MW of existing small hydro capacity (under 5MW) operating from approximately 120 sites, and at least 400MW of unexploited potential. With positive environmental policies now being backed by favourable tariffs for 'green' electricity, the industry believes that small hydro will have a strong resurgence in Europe in the next 10 years, after 20 years of decline. This paper summarises the different small hydro technologies, new innovations being developed, and the barriers to further development.

There is no universal standard definition of small hydro development. Different country adopts different specifications. Definition of SHP varies worldwide. In India install capacity less than 25MW is considered as small hydro. Although SHP technology is considered as a matured, reliable, environmental friendly and do not create any pollution during operation and offer highly reliable power with low running and maintenance cost. But India is lacking in implementing such projects effectively in spite of having good potential of 20,000 MW.India is need to go for structural change in SHP investment policies and funding practices for research and development in SHP in order to reach parity with China which is fastest growing country in overall hydro power sector including SHP. The paper is addressing present scenario of SHP in India, about its achievements, gaps in harnessing the untapped potential and emerging technologies. Furthermore it also emphasis on existing policies and its impl...
Energy Generation By Using Small Hydro Power-An Analysis
IRJET, 2022
Small or micro hydropower projects (SHP or MHP) are helpful for the solution of sustainable, eco-friendly, longterm, and renewable resources of energy for the future. Most of the electricity shortage is on the rural side of every country, so the alternate energy source for household power requirements is essential. Also, this source must be portable and easily operated by the common man. This paper shows different types of micro-hydro turbine which can be used in remote areas nearby river or water resources that should be more efficient and some studies also has analysis.

An overview of research and energy evolution for small hydropower in Europe
Renewable and Sustainable Energy Reviews, 2016
Europe has a large tradition of Small Hydropower stations (SHP); these proliferate wherever there was an adequate supply of moving water and a need for electricity. As electricity demand grew many of these plants were abandoned. Today with the rising price of energy, SHP can be a solution to help rural electrification, furthermore SHPs do not consume the water that drives the turbines. The advantage of this technology is extremely robust and systems can last for 50 years or more with little maintenance. This paper summarizes an overview of SHP Hydropower in Europe. Hydropower on a small scale, or micro-hydro, is one of the most cost effective energy technologies to be considered for rural electrification in less developed countries. Europe is a market leader of SHP technology. Optimal turbine designs are available and new technical developments offer automated operation of SHP. The present role of SHP in Europe in the development of renewable energy sources is discussed through this paper. The main producers of SHP electricity in Europe are Italy, France, Spain, Germany and Sweden. On the other hand, 10 European countries are ranked based on the total numbers of SHPs: Germany (7,512), Italy (2,427), France (1,935), Sweden (1,901), Spain (1,047), Poland (722), Romania (274), Portugal (155) and UK (120). The research shows that there is a considerable scope for development and optimization of this technology. This opens new perspectives because it has a huge, as yet untapped potential in most areas of Europe and can make a significant contribution to future energy needs.

Eastern Asia: Recent reports show that Asian continent has the highest potential of SHP (114,851 MW) based on the 10-MW definition compared with other regions of the world (Tables 1.1 & 1.2). Eastern Asia (excluding North Korea) has the highest SHP potential of 75.196 GW with the installed capacity of 40.48 GW. China belongs to Eastern Asia ranked first in the world for small hydropower potential (63,429 MW) that is about 55.2 % and 36.4 % of regional and global potentials respectively (Table 1.1). Further, Eastern Asia has installed 53.8 % (40,575 MW) of total SHP potential, which is the highest in the world. Central Asia: Of the Asian sub-regions, the Central Asia has the lowest SHP potential (4880 MW) with Kazakhstan having the largest potential (2707 MW) of which only 78 MW have been tapped. The overall exploitation in Central Asia is 8.4 % of the total sub-regional potential.
The Selection of a Small Hydro Power Plant (SHPP) Solution in Line with the Ecosystem
Facta Universitatis, Series: Working and Living Environmental Protection, 2019
Population growth and new forms of energy use have the effect that the energy demand grows year after year. The harmful influence of the use of fossil and nuclear fuels has influenced the intensive development of renewable energy sources (solar energy, small hydro power plants, wind energy, bio-renewable sources - biomass, geothermal energy). This paper gives an overview of the choice of design solution, technical parameters and the efficiency of small hydro power plants (SHPP) on small watercourses. Special attention in these considerations is dedicated to harmonization of selected solutions with natural resources and protection of ecosystems. In order to define the technical solution of one small HPP on a small watercourse, the following analyzes and studies need to be done: Hydrological study; Analysis of the available hydro potential; Pre-feasibility study of the chosen technical solution; Study on Environmental Impact Assessment; Analysis of the investment value of the elements...
