The Impact

Electricity is a necessity that must exist today, its use is always subject to binding. Most of the electricity comes from fossil energy-based power plants such as PLTU. Therefore, a solution was made by making a vortex water turbine to produce electrical energy. Utilizing a river flow with a small head of water, the water will enter the cross section. The flow will form a vortex because the shape of the section and the draft tube makes the lower side of the section have lower pressure. The vortex turbine will be designed to use a permanent magnet 150 watt AC generator. With a cross section of 60 x 55 x 150cm, draft tube 9.6 mm and turbine blade 30 x 50cm made of aluminum. On the framework will be used a 3 x 3.5 cm strip plate which is rolled. In order to withstand the impact of water on the blade, a 7 mm shaft is used and a nominal bearing life of 10274 hours. The resulting rotation is continued with a pulley with a diameter of 30 mm, 180 mm and with a belt type V material JIS K 6323 A 34.

<em>The need for electricity in Indonesia is very important considering the limited resources and the lack of manpower, making Indonesia desperately need to increase electricity generation. One source of energy that can be converted into electrical energy is tidal barrage using the tidal barrage method. The application of this energy is still very small in Indonesia but there are a number of areas that have the potential to be implemented by the power plant. Tidal power plants that utilize the potential energy contained in the differences in tides and tides of sea water by trapping water in dams and then moving water turbines and when the water turbine is connected to a generator can produce electrical energy. Related to how the output of the generated power can it is known by looking at what height the water level drives the turbine. This type of power plant is environmentally friendly because it does not damage the natural ecosystem and the dam can be used for various activities.</em><em></em>

Abstract The impact of post-combustion carbon dioxide capture on the performance of a power plant is evaluated. A model of a coal power plant with post-combustion temperature swing adsorption CO2 capture using sorbent-loaded hollow fibers is presented. The resulting performance and cost of carbon capture are compared with those of other adsorption-based technologies. A parametric analysis of the performance of the power plant with respect to key parameters in the hollow fiber module operation is presented. It is found that electrical energy consumption for the compression of CO2 is a major parasitic load common to all absorption technologies and accounts for almost half of the total parasitic load. The effect of source temperature, flue gas fan and coupling fluid pump flow rates on overall system performance is presented. The impacts of different carbon capture technologies on the same coal-fired power plant are compared. Hollow fiber modules had the lowest parasitic load on the power plant, followed by KS-2 based carbon capture.

The Impact

Cement manufacturing is an emission-intensive process. The cement industry is responsible for 8% of the global CO2 emissions, and produces a ton of cement uses up to 102 kWh of electrical energy, leading to a significant amount of indirect emissions depending on the emission intensity of the electricity source. Captive power generation can be potentially utilised as a mitigation approach to reduce emissions and as well as expenditure on electricity tariffs. In this study, a system dynamic simulation model is built to evaluate the impact of captive power generation on a cement plant’s net emissions and expenditure through electricity use, under different scenarios for carbon-tax, grid emission factor, and electricity tariffs. The model is then utilised to simulate a reference plant under realistic scenarios designed based on the conditions in Germany and United Arab Emirates. Furthermore, the model is utilised to calculate the payback period of investments on captive power plants under different carbon tax scenarios. The study concludes that a carbon tax policy on emissions through electricity utilisation could have an impact on incentivising the use of captive power generation and would lead to fewer emissions and expenditure during the cement plant’s lifetime.

Abstract Small hydroelectric power plants (SHP) have been considered as an alternative for the generation of electricity with reduced environmental impacts. Nevertheless, no studies have addressed changes in a particular kind of river macrohabitat commonly affected by SHPs, the knickzones. This study aimed to assess the impact of a SHP construction on the aquatic macroinvertebrate fauna associated with two basaltic knickzones located in Sapucaí-Mirim River, Southeast Brazil. The first, considered as a functional knickzone, follows the natural dynamics of the river flow and preserves the original rock substrate. The second, considered as non-functional knickzone, was permanently flooded after the SHP construction and the consolidated rock substrate was changed by fine sediment. Sampling was carried out in two seasonal periods and the data were analysed through multivariate analysis. It was observed differences in composition and structure of the macroinvertebrates community between the knickzones and periods. The functional knickzone exhibited a much higher richness, 72 taxa compared to 44 in the non-functional, as well as a large number of exclusive taxa (38, being only nine exclusive to the non-functional). Diversity, equitability and density mean values were also higher in the functional knickzone. The limnological parameters varied significantly between dry and rainy seasons but not between the distinct knickzones. This kind of macrohabitats and its potential role for the rivers biodiversity is practically unknown. In the scenery of fast SHP expansion, further studies and protection measures are necessary.

The Impact

The growth in volatile renewable energy (RE) generation is accompanied by an increasing network load and an increasing demand for storage units. Household storage systems and micro power plants, in particular, represent an uncertainty factor for distribution networks, as well as transmission networks. Due to missing data exchanges, transmission system operators cannot take into account the impact of household storage systems in their network load and generation forecasts. Thus, neglecting the increasing number of household storage systems leads to increasing forecast inaccuracies. To consider the impact of the storage systems on forecasting, this paper presents a new approach to calculate a substation-specific storage forecast, which includes both substation-specific RE generation and load forecasts. For the storage forecast, storage systems and micro power plants are assigned to substations. Based on their aggregated behavior, the impact on the forecasted RE generation and load is determined. The load and generation are forecasted by combining several optimization approaches to minimize the forecasting errors. The concept is validated using data from the German transmission system operator, 50 Hertz Transmission GmbH. This investigation demonstrates the significance of using a battery storage forecast with an integrated load and generation forecast.

The investigation of electrical energy management (EEM) in the industrial and commercial sector determines how energy management affects elec-tricity consumption and what makes its potential for being used to reduce peak demand of utility indus-tries. The aim of this paper is to analyze the contri-bution of electrical energy management in the industrial and commercial sector and highlight its challenges to the Tanzanian utility industry. Energy efficiency technology analyzed in this paper includes energy efficiency lighting and power factor improvement. The analysis found that, if EEM is properly implemented, a significant amount of energy could be saved and could be converted to monetary benefits which might facilitate the devel-opment of other activities. The utility industry can benefit from saving considerable amounts of energy as well as the reduction of peak demand which can minimize the race of stumbling on new energy sources and construction of new power plants. The saved energy can be distributed to other consumers so as to improve accessibility or reliability of the electrical system and consequently minimize the impact of environmental pollution.

The Impact

Reduced availability of the large quantities of water required for traditional wet condenser cooling systems has created a growing market for dry and hybrid cooling for power plants. These technologies significantly reduce overall water consumption, but with large capital cost and heat rate penalties. An important consideration in sizing air-cooled and hybrid condensing systems is the emergence of a spot market for electrical energy. Energy prices can vary over an order of magnitude, and are typically highest during summer conditions. This paper evaluates whether it may be more economical to over-size the cooling system to achieve lower backpressures during the summer and thus generate additional revenue when energy prices peak. A universal methodology for evaluating the impact of cooling system design on operating economics was developed. It consists of a capital cost database for the condensing system, a Gate/Cycle model used to evaluate the effect of cooling parameter selection thermal performance, climatological data to provide representative dry bulb and wet bulb temperatures for typical annualized operating profiles at each plant location, and historical spot market energy pricing for each plant location. Several different design points for the cooling system are examined to determine the optimum selection that maximizes the difference between revenue and cooling system capital cost recovery. A nominal 500 MW coal-burning power plant is used as the study basis to demonstrate the results of this methodology for both northeastern and southwestern sites in the USA.
