In an earlier paper (Kosnik, 2008), the potential for small scale hydropower to contribute to US renewable energy supplies, as well as reduce current carbon emissions, was investigated. It was discovered that thousands of viable sites capable of producing significant amounts of hydroelectric power were available throughout the United States. The primary objective of this paper is to determine t...

This paper contributes towards exploring the technical and institutional feasibility of small hydropower storage and pumped-storage schemes in Switzerland. Within the European and Swiss context of the facilitation of renewable energy technologies, which includes small hydropower (SHP), intermittent sources such as solar and wind increase the need for additional energy storage capacities. Hydrop...

Introduction According to the Swiss Energy Strategy 2050, which takes into account the phase out of the existing nuclear power plants, the mean annual hydropower production must be increased by 1.5 TWh/a under present framework conditions, eventually reaching 3.2 TWh/a if conditions are optimized (SFOE, 2016). In view of environmental and socio-economic constraints, this foreseen increase is ex...

1 Recent droughts and heatwaves showed the vulnerability of the electricity sector to surface water 2 constraints with reduced potentials for thermoelectric power and hydropower generation in different 3 regions. Here we use a global hydrological-electricity modelling framework to quantify the impacts of 4 recent drought and warm years on hydropower and thermoelectric power usable capacity worl...

In this paper a day-ahead planning algorithm for a multi-reservoir hydropower system coordinated with wind power is developed. Coordination applies to real situations, where wind power and hydropower are owned by different utilities, sharing the same transmission lines, though hydropower has priority for transmission capacity. Coordination is thus necessary to minimize wind energy curtailments ...

For 7-8% growth rate that India is aspiringfor, its energy needs will increase correspondingly. The challenge is to provide desired quality power in a sustainable manner and at reasonable cost. Small hydropower has the potential of about 15000 MW in India and considered to be a reliable source of electricity generation. Three run-of river small hydropower projects in India has been identified a...

Energy storage is a key issue when integrating large amounts of intermittent and nondispatchable renewable energy sources into electric power systems. To be able to maintain the instantaneous power balance and to compensate for the influence of power fluctuations that might result from renewable sources, flexible capability for power control is needed. Therefore, sufficient energy storage with ...

This paper presents results from a seismic vulnerability analysis of the components of hydropower systems in Canada. A number of dams and their associated components (hydropower plants, switchyards, transmission towers, and supplementary equipment) at selected locations in western and eastern Canada were analyzed in the study. The seismic vulnerability for a given hydropower component was estim...

Hydropower represents approximately 20% of the world’s energy supply, is viewed as both vulnerable to global climate warming and an asset to reduce climate-altering emissions, and is increasingly the target of improved regulation to meet multiple ecosystem service benefits. It is within this context that the recent decision by the United States Federal Energy Regulatory Commission to reject stu...
