Dams for water supply usually represent an untapped hydroelectric potential. It is a small energetic potential, in most situations, usually requiring a particular solution to be viable. The use of pumps as power turbines often represents an alternative that enables the power generation in hydraulic structures already in operation, as is the case of dams in water supply systems. This potential can be exploited in conjunction with the implementation of PV modules on the water surface, installed on floating structures, both operating in a hydro PV hybrid system. The floating structure can also contribute to reducing the evaporation of water and providing a small increase in hydroelectric power available. This paper presents a pre-feasibility study for implementation of a hydroelectric power plant and PV modules on floating structures in the reservoir formed by the dam of Val de Serra, in southern Brazil. The dam is operated to provide drinking water to about 60% of the population of the city of Santa Maria, in the state of Rio Grande do Sul, in southern Brazil. The pre-feasibility study conducted with Homer software, version Legacy, indicated that the hydroelectric plant with a capacity of 227 kW can operate together with 60 kW of PV modules. This combination will result (in one of the configurations considered) in an initial cost of USD$ 1715.83 per kW installed and a cost of energy of USD$ 0.059/kWh.

“…The size of the bubbles indicates population. However, evidence is growing in the literature [11,12] that distributed generation options represent cost optimal solutions for many rural areas in Sub-Saharan Africa as the grid extension options represent more expensive electricity provision for places far away from the existing power grids [6,7]. This could especially appear to be the case for the island states which are even more distant from fuel supply sources than most of the rural African communities.…”

Abstract:The study presents a cost effective electricity generation portfolio for six island states for a 20-year period . The underlying concept investigates whether adding sizeable power capacities of renewable energy sources (RES) options could decrease the overall costs and contribute to a more sustainable, indigenous electricity generation at the same time. Often, island states rely on fossil fuels which, apart from dependence on foreign resources, also includes an additional, significant transport cost. This is an extra motive to study the extent in which island states represent primary locations for RES technologies. For the aims of the present study an optimization model has been developed and following numerous runs the obtained results show that installing PV and battery capacities can delay-reduce the huge investments in fossil options in early periods. Thus, investment on RES can have a positive, long-term effect on the overall energy mix. This prompt development can happen without adding new subsidies but there is a need to address the existing socio-economic barriers with intelligent design of financing and economic instruments and capacity building as discussed in the conclusions.

“…However, Hall et al in [165] arrive at only about 0.6 PWh/y for all (small and large) hydro resources for the US. Interestingly, mainly developing countries would benefit from future hydropower development, such as the Democratic Republic of the Congo and Cameroon which feature Africa largest hydropotential resources [166]. In fact, there are plans for two new hydroelectric stations at the Congo River with a combined output of more than 40 GW, producing 370 TWh annually.…”

“…The latter are applied in very small communities, often in remote areas that would be uneconomic to supply from a grid. Small hydro projects are characterized by small infrastructure and hence low construction cost and low environmental impact, which makes the ideally suited for deployment in developing countries where electrification is still low (see case studies from Cameroon: [166]; India: [49,163]). The International Energy Agency has formed working group called the Hydropower Implementing Agreement with a common interest in advancing hydropower worldwide (www.ieahydro.org).…”

Electricity is perhaps the most versatile energy carrier in modern economies, and it is therefore fundamentally linked to human and economic development. Electricity growth has outpaced that of any other fuel, leading to ever-increasing shares in the overall mix. This trend is expected to continue throughout the following decades, as largeespecially rural-segments of the world population in developing countries start to climb the "energy ladder" and become connected to power grids. Electricity therefore deserves particular attention with regard to its contribution to global greenhouse gas emissions, which is reflected in the ongoing development of low-carbon technologies for power generation. The focus of this updated review of electricity-generating technologies is twofold: (a) to provide more technical information than is usually found in global assessments on critical technical aspects, such as variability of wind power, and (b) to capture the most recent findings from the international literature. This report covers eight technologies. Seven of these are generating technologies: hydro-, nuclear, wind, photovoltaic, concentrating solar, geothermal and biomass power. The remaining technology is carbon capture and storage. This selection is fairly representative for technologies that are important in terms of their potential capacity to contribute to a lowcarbon world economy.
