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 ...

A conceptual framework for real time estimation of WFP for small hydroelectric power plant
It is believed that the power sector, particularly hydroelectric power, contributes to a very high consumption of fresh water in terms of evaporation from storage reservoirs. Robust methods of water footprint (WFP) assessment will eventually help in the pricing of water and energy. Conventionally, WFP for hydropower plants is estimated by dividing the gross/net evaporation losses by power ...

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 (UNIDO) and the International Center on Small Hydro Power (ICSHP), a China-based, non-profit body that promotes this form of energy worldwide, launched the site last month (13 February). ...

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 ...

The institutional co-evolution in diffusion of hydroelectric power technology
The introduction and significant momentum on diffusion of wind power as a new technology for energy production involve a push for changing the institutional framework in the energy sector. The introduction of hydro (electric) power technology and the following institutional change process may be compared to the introduction of wind power 90 years later. In this paper, the main focus is on the ...

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 ...

SHP stations and integrated rural development: a multivariate statistical approach
The multi-functional role of the rural space is gradually being enhanced in recent decades, as agriculture seems to be losing its leading position. The diversification of local economies through the exploitation of natural resources is being highlighted as a fundamental driving force for development. Renewable Energy Resources (RES) and, more specifically, the establishment of Small Hydropower ...

Understanding water-society nexus: insights from Turkey's small-scale hydropower policy
Turkey's recent venture involving the construction of hundreds of small-scale hydropower projects is a significant trend, both in regard to its contribution to Turkey's hydroelectricity production and the social and environmental impact of these projects at the local level. Turkey's hydropower policy was premised on a conventional understanding of water driven by science, technology, and the ...

Forecasting monthly energy production of small hydropower plants in ungauged basins using grey model and improved seasonal index
A first-order one-variable grey model (GM(1,1)) is combined with improved seasonal index (ISI) to forecast monthly energy production for small hydropower plants (SHPs) in an ungauged basin, in which the ISI is used to weaken the seasonality of input data for the GM(1,1) model. The ISI is calculated by a hybrid model combining K-means clustering technique and ratio-to-moving-average method, ...

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 ...

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 ...

Renewable Energy Market in Indonesia
The development of renewable energy in Indonesia has stalled in recent years, especially wind and solar PV power. By the end of 2018, cumulative installed solar and wind capacity in Indonesia just reached 136MW, which is at a relatively low level compared with other Southeast Asian countries. It is a recognized fact that 2019 was the year of Vietnam’s renewable energy explosion, with a new ...
