The One

When the first large-scale hydroelectric power plants were built in Sweden at the beginning of the twentieth century, the waterfall became a twofold symbol of the Swedish nation. On the one hand, the harnessed waterfall promised unlimited energy and economic growth, and thus turned into a unifying symbol of a national productive landscape. On the other hand, the unharnessed wild waterfall, to be enjoyed by tourists seeking refuge from the modern industrial world, became a symbol of a national recreational landscape. This situation, however problematic, did not result in conflict. Taking a look at the first two state-built water power plants in Sweden, I trace how the two contrasting concepts of landscape were harmonized within public discourse. I demonstrate how engineers, architects, conservationists, tourist organisations, and journalists together produced a broad public acceptance of the drastic changes in the national landscape brought about by the construction of these power stations.

Hydroelectric Power Plants

Countries need to develop sustainable energy policies based on the principles of environmental sensitivity, reliability, efficiency, economy and uninterrupted service and to maintain their energy supply in order to increase their global competitiveness. In addition to this impact of sustainable energy supply on the global world, maintenance processes in power plants require high costs due to allocated time, materials and labor, and generation loss. Thus, the maintenance needs to be managed within a system. This makes analytical and feasible maintenance planning a necessity in power plants. In this context, this study focuses on maintenance strategy optimization which is the first phase of maintenance planning for one of the large-scale hydroelectric power plants with a direct effect on Turkey's energy supply security with its one fifth share in total generation. In this study, a new model is proposed for the maintenance strategy optimization problem considering the multi-objective and multicriteria structure of hydroelectric power plants with hundreds of complex equipment and the direct effect of these equipment on uninterrupted and cost-effective electricity generation. In the model, two multi-criteria decision-making methods, AHP and COPRAS methods, are integrated with integer programming method and optimal maintenance strategies are obtained for 571 equipment.

The Southeastern Anatolia Project (GAP), encompassing 27 dams and 19 hydroelectric power plants, is a large-scale water management program aiming at an increase in domestic electricity production and the development of vast irrigation schemes for agriculture. In spite of numerous benefits experienced in the area, there is also a multitude of impacts observed on the environment. The Coruh River is the longest river of the East Black Sea region and is of high economic importance to Turkey because of its largely exploitable hydropower potential. The Coruh project consists of 27 planned dams and hydroelectric power plants. The planned dams have the potential to cause serious environmental effects in upstream Turkey and downstream Georgia. Equitable, rational, and optimal utilization of transboundary water resources can be achieved through a scientific study, which will determine the true water needs of each riparian country. A precise assessment is needed of the economic, ecological, and social problems on the basis of the environmental impact and cumulative effect assessment reports.

In this paper have been considered the basic approaches and main principles of geoengineering. The “geoengineering” term transformation, as well as the term’s specifications of use in the Russian-language scientific literature, and the application area have been demonstrated. In connection with the growing biosphere problems, it has been proposed to classify mining and global pollution (i.e. pollution of atmosphere, hydrosphere and soil) as geoengineering. Special attention has been paid to the possible risks of geoengineering (including at large reservoirs of hydroelectric power plants), and the necessity for detailed study before launching of large-scale projects. The UN approach to geoengineering management has been characterized, and the main principles of geoengineering regulations have been presented. An extended classification of geoengineering technologies has been proposed.

Reliable Power Supply

The prospects for the use of solar power plants in the world of environmental hydraulic engineering are analyzed. Recommendations on the constructive combination of elements of structures of environmental hydro technical complexes with solar photovoltaic installations (SFEU) are presented. The variants of their most rational location on the building of hydroelectric power stations (GES) of different types are considered. It is established that the buildings of small and medium-sized hydroelectric power plants represent significantly more constructive possibilities for combining the GES building with the SFEU. The relationship between the area suitable for placing solar cells and the diameter of the turbine impeller is determined. With a decrease in the diameter of the impeller, the relative surface area suitable for placing solar cells increases. It is noted that it is most appropriate to combine SFEU and small hydroelectric power plants with non-combined buildings with transformers on the downstream side. At medium-sized hydroelectric power plants of various types, the conditions for combining are approximately the same. The results of the work can have an impact on obtaining a reliable power supply system based on renewable energy sources, improving the safety of the GTS (hydro technical structures) of existing hydroelectric facilities in the context of increasing the efficiency of the introduction of ”green“ technologies in the energy sector while reducing biosphere pollution and greenhouse gas emissions, including in hard-to-reach areas of agricultural areas where there are problems with centralized water supply.

The One

The development of small scale hydroelectric power plants in Norway is determined by natural conditions, policies, attitudes and property rights. The owner of the river is the central decision maker. It is he who decides whether he will develop the power plant himself, Whether he wants to enter into a contract with an external investor and let him develop the power plant, whether he will sell his property rights or postpone the decisions. All available choices will involve risk. In order for him to make the best choice he must find the certainty equivalent to each of the choices and choose the one with the highest certainty equivalent. This is the first time the utility theory of John von Neumann and Oskar Morgenstern has been applied to decision makers in the hydro power industry in Norway.
