The implementation of many small power stations compensates the closing of powerful large power plants as part of the German Energy Transition is compensated. It is unclear how site decisions are made, which actors are involved, and which economic, ecological, and social consequences occur. The quantitative study consists of a written postal survey of renewable energy plant operators, concerning central aspects of project development. The study found strong regional disparities concerning the entrepreneurial behavior of plant operators of renewable energies, a low importance of socio-institutional and socio-cultural parameters, a great relevance of micro-social environment during site planning of renewable energy plants, and that plant operators are highly influenced by economic and individual desires. It may be concluded that the perspectives operators have on the Energy Transitions must be more systematically included into the discourse regarding the sustainable deployment of renewable energies, as they reveal significant disparities with topics that are emphasized by the public (e.g., landscape aesthetic, citizens’ participation). It was shown that the challenges and problems that arise in the context of regional energy transformation cannot be generalized beyond regional circumstances; rather, they must be regarded as specific regional phenomena that have to be overcome by means of regionally adapted energy concepts.

An information system, built-up from a database and a multiple criteria decision support system, was developed to collect, process, store, assess and disseminate information on renewable energy power stations in Greece. This system is used to support decision-making, control, analysis and visualization regarding the existent installations, and the middle term forecasting of similar ones. The results show that, at national level, the wind and solar photovoltaic power stations, except the solar systems of private producers, are acceptable investments. The low national level of the capacity factor, 18 % for wind and 11% for photovoltaic power stations, is one of the reasons for their low productivity. The study relates to the prices paid for renewables electricity in Greece. The cost of the electric energy generated, and also the total cost of all wind and solar power stations, are high as compared to those of conventional fuels based systems. The wind power systems have acceptable return of investment (9%/y), internal rate of return (20%/y) and payback period (6-11 y). The solar stations have low internal rate of return (<9%/y) and return of investment (0.57%/y) and long-term payback period (22-35 y). Although the renewables are attractive investments with acceptable nationwide levels of financial indexes, they present high variations from one power station to another. Most wind and solar power plants must increase their competitiveness, and some must revise their feasibility criteria and design of installations. Thus, units with higher profits must be developed to an optimal installed rated power, while others must be reconsidered.

The Impact

The trade-off between economic growth and ecological improvement has always become an important and difficult issue for many countries, especially for developing countries. Due to a long-term extensive economic growth pattern, the regional resource allocation deviates from the optimal, especially the existence of energy misallocation, which hinders the maximization of economic output. Therefore, considering the characteristics and heterogeneity of resource endowments in different regions and increasing renewable energy consumption, that is, promoting energy transition, is it capable of sustainable development under China’s actual conditions? The exploration of the issue is a core step in the research of the impact of renewable energy on industrial green transformation. Based on the panel data of 30 regions in China from 2009 to 2016, this paper constructs a threshold model from the perspective of regional energy misallocation and empirically tests the nonlinear mechanism of renewable energy consumption to promote industrial green transformation. The results show that China’s energy allocation efficiency is low, there is a certain misallocation phenomenon, and the improvement effect in recent years is not satisfactory. Further, the relationship between renewable energy consumption and industrial green transformation is not a simple linear relationship, but a double threshold effect due to regional energy misallocation. In areas with severe energy misallocation, renewable energy consumption does not have a significant boost to industrial green transformation. Finally, this paper proposes the policy enlightenment of promoting industrial green transformation from the aspects of performance evaluation, market reform, and factor flow.

AbstractIn this work we explore the ramifications of incoming changes brought by the energy transition, most notably the increased penetration of variable renewable energy (VRE) and phase-out of nuclear and other conventional electricity sources. The power grid will require additional flexibility capabilities to accommodate such changes, as the mismatch between generation and demand is bound to increase. Through mathematical modeling and optimization, we simulate the German power grid and investigate the requirements of on-grid large-scale storage. Different scenarios are evaluated up to 2050, when 80% of the gross electricity consumption is planned to be provided by renewable energy. Dispatchable power plants will play a key role in the transition to an energy mix with high shares of VRE. Around 120 GW of additional large-scale storage are required until 2050. Between the electrochemical technologies evaluated, lithium-ion was the best candidate. A strong reliance on dispatchables was observed, in case the commissioning of VRE plants goes slower than planned. Energy curtailment increases with VRE shares, with up to 14 TWh curtailed in high VRE scenarios in 2050.

Pakistan is identified to be one of the next-11 the top emerging economies of the world after the BRICS. This emphasizes the establishment of a competitive electricity market that can fulfil the demand of the country considering the environmental concerns. In this scenario reliability of power is something that cannot be compromised. Dispatchable power stations play a major role in balancing supply and demand; this balance is essential for maintaining the power cuts free country. All dispatchable power stations incorporate some form of storage particularly thermal or chemical (i.e. a stored fuel).  Earlier dispatchable power was regarded as the generation which can start quickly and meet the peak demand requirements but arrival of renewables in power system has increased worth of its presence since it has just not to supply peak demand but also to meet during the unavailability of other renewable energy sources because of their intermittent behavior meanly at times of dark hours and slow wind speed. This study considers the viability of Concentrated Solar Thermal Power in Pakistan and thoroughly analyses several characteristics i.e., Availability of fuel, water, road and communication network, flexibility and environmental impacts of the technology for the cite of Tharparkar.

Abstract GIS-based analysis of energy demand facilitates the planning and implementation of renewable energies in urban space. The process of preparing an urban energy concept concerns many actors and facilities, but increases also the acceptance of the energy transition in the proximity. A calculation of energy potentials in the city of Augsburg (Germany) illustrates an usual way of spatial energy planning.

The paper considers the problems of designing autonomous power supply systems using the renewable energy resources. The efficiency of using energy resources in conditions of growing prices for electricity brings significant saving of both energy and financial factors. The analyses show that the main losses of energy resources are the result of inefficient use, distribution and consumption of electrical energy. There has been stated one of the most important problems of energy saving: many existing consumers are located at a significant distance from centralized power supply systems. Today connecting such consumers to large power grids is economically inexpedient. These facilities are supplied from the stand-alone power plants. According to the program of energy saving and energy efficiency improvement of FGC UES, PJSC, reducing electricity consumption for auxiliary needs of transformer substations is one of the main mechanisms for the program implementation.

The Impact

The operation of large power plants, including power stations, and combined heat and power stations, causes the emission of significant amounts of gaseous pollutants into the environment. As a result, in the urban and agricultural areas occurs a pollution of undesirable gaseous substances, such as nitrogen and sulfur oxides. This is especially dangerous for living organisms, soil and water, because, in combination with water vapor, these pollutants are the cause of acid rain. In addition, nitrogen oxides participate in the formation of ground-level ozone, which affects both human health and the condition of existing vegetation. Therefore, the distribution of air pollutants (NO2, SO2 and O3) in the selected urban and rural areas, under the influence of power plants, located in the Lodz Voivodeship, in Poland, in Central-Eastern Europe, was analyzed for a 10-year period (2007–2016). As a result, it was possible to evaluate the impact of the entry into force of Directive 2008/50/EC of the European Parliament and of the Council of 21 May 2008 “on ambient air quality and cleaner air for Europe” on the changes in emissions and concentrations of pollutants in selected locations. As a result of the analysis, a significant decrease in the concentration of SO2 (by 75% in the urban area and by 59% in the rural area), and small changes (from - 8% to + 12%) in NO2 and O3 concentrations in ambient air were found. This indicates the effectiveness of actions aimed at reducing SO2 emissions, however the influence of the power plants on the concentration of air pollutants in these areas is not clear. At the same time, considering the criterion of permissible concentration of ozone and nitrogen dioxide, although the air quality did not improve, the air quality index can be considered as being in the category of "good".

Planning Processes

Abstract. The number of actors in the German Energy Transition as well as the planning complexity increases and new spatial implications emerge in contrast to the conventional energy system. In planning processes for Renewable Energy Technologies mostly economic approaches are chosen, but simultaneously the number of social conflicts related to wind power plants or solar energy plants is on an all-time high. The aim of the study is therefore to identify the essential parameters of a sustainable expansion of renewable energies from the diversity of potential influencing factors and to illustrate them using a regional case study and GIS. The analyses reveal the great regional assertiveness of photovoltaics, whereby wind energy can assert itself due to social parameters also at some locations. Beyond this, it is to be stated that renewable energies find themselves in intense economic and social competition for space, although the most compatible spatial solutions have not always been able to prevail so far. Nevertheless, the presented approach offers a sophisticated method to minimize the social conflicts that arise in the context of the energy system transformation.

Negative Effects

The economic impacts of the German Renewable Energy Act (EEG) are of considerable importance for the discussion of the energy transition in Germany (Energiewende). The Energiewende implies structural changes of the energy system by deploying Renewable Energy (and energy efficiency) Technologies (RET), but it also may induce structural changes for the overall economy, with uneven effects on a sub-national level. North-Rhine Westphalia (NRW) is an ideal case to study such regional disparities, since this federal state has scarce per-capita renewable energy sources, whereas it stands out for its energy intensive industry and fossil-fuel based power plants. In order to support renewable energy policies, mostly gross impact assessments of RET deployment have been carried out both on national and regional levels. By definition, such analyses result in positive assessments, since only expansionary effects resulting from additional demand for RET are accounted for. This paper, in contrast, presents a net impact assessment of the EEG on the NRW economy of both expansionary and contractionary effects. The latter consist of negative income effects, increased production costs and, the crowding-out of conventional energy due to the renewable energy financing mechanism (i.e., electricity surcharge), as well as its preferential status for feed-in. Our findings show how North-Rhine Westphalia, with regard to the operation of RET, suffers disproportionally from negative effects in relation to the value addition of its economy in comparison to the rest the country, whereas it benefits marginally from the production of such facilities.
