The chapter focuses on explaining the construction of author's own engineering-level model which calculates energy production based on historical water level and flow rate readings as well as economic factors such as net present value of the proposed investment on the example of a HPP on the Wkra River. The model methodology assumes the identification of location's hydrological features and translates them into a set of contingency scenarios. Various internal costs, such as maintenance or labor costs, related to normal HPP activity and taxation are discussed and incorporated into the economic part of the model. Test case results indicate that for a series of good years in terms of water flow and electricity production, full repayment of initial investment costs is possible after less than three years. Results for the chosen modernization parameters indicate that within 10 years of installing a new turbine, even the most pessimistic case would bring added value to the real estate valuation.

Resource Function

One of the promising areas for the development of renewable energy in Ukraine could be the expansion of the small hydroelectric power plant (HPP). The main obstacle to this is the absence of a sharp increase in the profitability of such facilities, since the operation of small hydropower facilities is based on the use of only one of their resource function, which is not consistent with the need to intensify the use of nature and integrated use of natural resources. The most expedient direction of increasing the efficiency of functioning of small hydropower facilities, increasing their economic, social and ecological significance is the organization of regional natural-economic complexes (RPGK) whose activity is based on the combination of electricity production, maintaining the sustainability of the recreation ecosystem, can significantly increase their market value. Also important is the issue of software to solve this problem.

Maintenance Plan

<p>This article presents a guide to designing a maintenance plan for any industrial system. As an example, it develops a maintenance plan for highly reliable equipment, such as a hydroelectric power plant, where instant availability and reliability are crucial in its operation. The development of the proposal serves as a basis for the transversal development of any industrial system that has the same operational objectives (manufacturing lines), transport (trains, aircraft) and also involves safety and environmental aspects in its proper functioning. Today’s society requires that there are more and more industrial processes in which the maximum availability of the systems must be guaranteed, and at the same time there must be a minimum number of incidents that prevent the unavailability of the process. The methodology used has consisted firstly of dividing the complex industrial system into systems to be analysed on the basis of the functions they have to perform, then on the basis of the fault history a list of potential faults to be analysed has been determined, taking into account the risk of the system itself. From here, the systems of the hydroelectric plant have been classified to determine the priorities of actions. The different maintenance techniques to be applied have been carefully considered, focusing on the need to analyse condition-based maintenance techniques, such as predictive techniques, which allow us to define the point of potential failure based on parameters, and thus be able to plan maintenance actions in a justified manner. In the specific case of a hydroelectric generation plant, the fundamental objective is based on the commitment to<br />operate in the electricity market (high reliability and immediate availability), and the performance of maintenance actions imply in most cases the shutdown of the plant and therefore the loss of income from electricity production. Finally, a design of a justified maintenance plan for a hydroelectric power plant has been proposed based on the methodology explained.</p>

Shed Light

Recent developments of the Grand Ethiopian Renaissance Dam aiming to utilize the River Nile’s water for electricity production sparked serious debates in Africa. Under construction since 2011, the project has severe geopolitical consequences not only in its immediate neighbourhood but also in the downstream countries such as Sudan and Egypt that are almost exclusively reliant on the river’s water for industrial, agricultural, and household purposes. Although the Nile is the longest river on Earth, its water is shared by tens of millions of users in a region characterized by water scarcity. Therefore, the Ethiopian dam, with its potentially negative consequences, is considered an existential threat for Egypt and contributes to the political tensions between the two distant countries.This analysis aims to present the political choices behind this megaproject focusing on Egypt, Sudan, and Ethiopia and the impacts that different scenarios of water usage (how fast the reservoir behind the Dam is filled) may have on the downstream countries. In this sense, negotiations on the completion of the Dam and the hydroelectric power plant are crucial for Egypt’s water resources. My analysis tries to shed light on the importance of this topic in the Egyptian political discourseand show the changes in the political leeway of Egyptian leadership since 2011. As the case provides yet another illustration of interconnected environmental issues, my research also highlights the political and economic dilemmas embedded in similar situations.

The Impact

When planning the construction of a hydroelectric power plant, an important segment is adequate monitoring of water quality. With an appropriate monitoring program, the multifunctional use of artificial lakes is enabled. Eutrophication (nutrient over-enrichment) of water in a lake is a phenomenon that has been noticed in all lakes. The consequence of eutrophication is the endangerment of the aquatic ecosystem. Eutrophication is a phenomenon that occurs as a response of the aquatic ecosystem to the increased concentration of nutrients, phosphorus (P) and nitrogen (N), due to natural and anthropogenic activities. Recent research indicates a correlation between local climate change and water circulation and the impact of climate change on all phenomena in the hydrological cycle. Temperature fluctuations, huge amounts of rain when precipitation is analysed, constant heating and increase in humidity all affect more intense eutrophication. The key conclusions of the research dealing with the construction of the hydroelectric power plant in Komarnica are: to introduce monitoring (permanent control) of water quality in lakes in order to minimize or control, even prevent eutrophication. Each artificial lake has its own unique characteristics. The dependence of chlorophyll, phosphorus and lake volume varies depending on the month, season and year. The proposal for the lake that will be built on Komarnica, which is part of the future hydroelectric power plant, is a monthly monitoring of the concentration of chlorophyll, nutrients and the volume of the lake. Seasonal monitoring depends on precipitation, hydrological and limnological characteristics and trends of dry and rainy episodes. Analyzes and previous research have shown that the introduction of mandatory parameters for monitoring water quality does not increase the cost of electricity production and energy conservation, but significantly improves and enhances the quality of the environment.

Impacts Of Climate Change

Climate change is a major threat to industrial development because of its adverse effects on the energy sector, especially hydroelectric power plants. This paper focuses on the analysis of the impact of climate change on the Mono River basin and the implications for the electricity production of Nangbéto Hydroelectric Power Plant. The approach consisted of combining historical hydrological data and physical, technical, and economic information to analyze the extent to which variations in average rainfall and global warming impacted the operation of the Nangbéto Hydroelectric Power plant. Based on the curves obtained, the impacts of climate change on the Mono River and on the operation of the Nangbéto Power Plant were recorded. Also, the management of the Nangbéto dam water retainer by the current operator was analyzed to highlight the strengths relating to the optimization of electricity production and the economic profitability of the plant. Keywords: Climate change, hydropower plant, optimization, hydrological data.
