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.

The Impact

Biodiversity loss is accelerating rapidly in response to increasing human influence on the Earth’s natural ecosystems. One way to overcome this problem is by focusing on places of human interest and monitoring the changes and impacts on the biodiversity. This study was conducted at six sites within the influence area of the Santo Antônio Hydroelectric Power Plant in the margins of the Madeira River in Rondônia State. The sites cover a latitudinal gradient of approximately 100 km in the Brazilian Amazon Basin. The sampling design included six sampling modules with six plots (transects) each, totaling 30 sampling plots. The transects were distributed with 0 km, 0.5 km, 1 km, 2 km, 3 km and 4 km, measured perpendicularly from the river margin towards the interior of the forest. For sampling the ground-dwelling ants, the study used the ALL (ants of the leaf litter) protocol, which is standardized globally in the inventories of ant fauna. For the purpose of impact indicators, the first two campaigns (September 2011 to November 2011) were carried out in the pre-filling period, while campaigns 3 to 10 (February 2012 to November 2014) were carried out during and after the filling of the hydroelectric reservoir. A total of 253 events with a total of 9,165 occurrences were accounted during the monitoring. The ants were distributed in 10 subfamilies, 68 genera and 324 species/morphospecies. The impact on ant biodiversity during the periods before and after filling was measured by ecological indicators and by the presence and absence of some species/morphospecies. This is the first study, as far as we know, including taxonomic and ecological treatment to monitor the impact of a hydroelectric power plant on ant fauna. Until recently, most studies conducted on hydroelectric plants, located in the Amazon Basin, were carried out after the implementation of dams in order to assess their impacts on the environment and biodiversity (Benchimol and Peres 2015, Latrubesse et al. 2017, Sá-Oliveira et al. 2015). Recent studies on dam impacts have begun to be conducted prior to dam implementation (e.g. Bobrowiec and Tavares 2017, Fraga et al. 2014, Moser et al. 2014), thus providing a better overview of the impact and a better assessment of its magnitude.

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>

Choir IR, Iskandar J, Parikesit, Partasasmita R, Husodo T, Kumoro J, Megantara EN. 2018. The local management andsustainability of swidden farming in the Villages of Bojongsalam and Sukaresmi, Upper Cisokan Watershed, West Java, Indonesia.Biodiversitas 19: 1054-1065. In the past, the swidden farming (huma or ladang) system had been predominantly practiced by villagepeople of West Java. Nowadays, however, the huma farming has rarely been practiced by the village people of West Java due to thegovernment policy, and environmental and socioeconomic changes. The local community who reside in the Villages of Bojongsalamand Sukaresmi, the upper stream of Cisokan, West Java, Indonesia, has still practiced both the wet rice field (sawah) and the humafarming in the private land, production forest of a state-owned forest company (Perhutani), and a state-owned electric company (PLN)project land. Recently some areas of the huma land have been used for the project of the Hydroelectric Power Plant of the UpperCisokan Pumped Storage (UCPS). As a result, the sustainability of huma system of the local people of Bojongsalam and Sukaresmi hasbeen seriously disturbed. The aims of this study were to elucidate the local management of the huma farming systems that areundertaken by local people of Bojongsalam and Sukaresmi Villages, and to analyze the sustainability of the huma farming of localpeople of Bojongsalam and Sukaresmi Villages as affected by the UCPS Hydroelectric Power Plant project. The qualitative method wasused, while several techniques of collecting the primary data, namely observation and in-depth interviews with informants were appliedin this study. The results of study showed that the local management of the huma farming has been annually undertaken by the localpeople of Bojongsalam and Sukaresmi, including deciding the location of huma plot, preparing the land (cutting shrubs and burningvegetation biomass), planting rice (ngaseuk) and other annual crops, weeding (ngored) and providing chemical fertilizers (mupuk),controlling pests, harvesting rice (dibuat), and fallowing land. Based on analysis of the emergent properties of the agroecosystem ofhuma farming, it can be predicted that productivity, stability, equitability, and sustainability of the huma farming systems ofBojongsalam and Sukaresmi Villages tend to be low in the near future due to the impact of UCPS Hydroelectric Power Plant project.
