Investments in hydropower pumped storage projects (PSP) are subjected to a high degree of uncertainty. In addition to normal uncertainties in hydropower schemes, the profit of a pumped storage scheme is dependent on the margin between power prices for buying and selling, which is difficult to predict without a power purchase agreement (PPA). A PSP without a PPA and without known construction costs requires quantification of the uncertainties in order to make qualified decisions before investing in such projects. This article demonstrates the advantages of using Monte Carlo (MC) simulations as a tool in the economic analysis of PSPs. The method has been tested on a case study, namely the Tamakoshi-3 Hydropower Project (HPP) in Nepal. The MC method is used to calculate the probability distribution of the net present value of installing reversible units in the Tamakoshi-3 HPP. The calculations show that PSPs may be profitable in Nepal, given a beneficial development of the power market. The MC method is considered to be a useful tool for economic analysis of PSPs. In this case study of installing reversible units in the Tamakoshi-3 HPP, there are many uncertainties, which the MC simulation method is able to quantify.

AbstractMultiple trait introgression is the process by which multiple desirable traits are converted from a donor to a recipient cultivar through backcrossing and selfing. The goal of this procedure is to recover all the attributes of the recipient cultivar, with the addition of the specified desirable traits. A crucial step in this process is the selection of parents to form new crosses. In this study, we propose a new selection approach that estimates the genetic distribution of the progeny of backcrosses after multiple generations using information of recombination events. Our objective is to select the most promising individuals for further backcrossing or selfing. To demonstrate the effectiveness of the proposed method, a case study has been conducted using maize data where our method is compared with state-of-the-art approaches. Simulation results suggest that the proposed method, look-ahead Monte Carlo, achieves higher probability of success than existing approaches. Our proposed selection method can assist breeders to efficiently design trait introgression projects.

The objective of this work is to establish a framework for the development of an economic analysis tool for floating offshore wind platforms built in concrete. The operation and usefulness of the beta version of a software, called Arcwind, is explained. It calculates the main economic aspects of offshore wind platforms built in concrete considering different locations in the European Atlantic Arc. This software allows the user to select different input parameters such as: the type of platform, the installation area of the farm, its specific location and in this way create different analysis scenarios. This paper analyzes the case study to install TELWIND® offshore concrete floating platforms in the Canary Islands, in Spain. The software provides data on the main economic parameters of the farm, such as Levelized Cost Of Energy (LCOE), Net Present Value (NPV), Internal Rate of Return (IRR), Pay-Back Period (PBP), as well as the main costs: cost of conception and definition, cost of design and development, cost of manufacturing, cost of installation, cost of operation and cost of dismantling. Using these parameters, a first analysis of the viability of this type of floating technology built on concrete is shown.

Aims: This study analyses the economic performance and gender distribution of the small-scale aquaculture of Ghana using Net Present Value (NPV), Internal Rate of Return (IRR), Cash flow as well as gender distribution of the small-scale aquaculture of Ghana.  Study Design: This study is exploratory in its design. The study identified certain relationships and associations. Data was gathered from a sample drawn from a population.  Questionnaire-based interview was designed and administered to the small scale fish farmers in the Sunyani metropolis. Both quantitative and qualitative research methods will be employed for the study. A case study method will also be used due to the fact that it has the benefit of permitting for an intensive collection of data required to fulfil the goals of the research Place and Duration of Study: The study was conducted at the Sunyani Municipality in the Brong Ahafo Region of the Republic of Ghana between November 2017 and February 2018. Methodology: The study randomly selected 20 farms out 40 farms and farmers interviewed using questionnaire. A 600 m2 pond was further selected as a model of the small-scale aquaculture and used to perform the economic analysis. Results: The total start-up capital for a 600-meter square pond is estimated at $2693.15. Huge part, 56.9 percent, of the amount goes into fixed investment like pond construction, acquisition of land, and farm buildings. The economic analysis shows a viable industry with an estimated NPV of $605.4484 and IRR of 24.19 percent.    With gender, the study reveals a huge gap in man-woman distribution in the fish farming trade. Majority of the farms surveyed did not females, with the male having 77 against the female with 23%. Conclusion: The study has found a viable aquaculture industry with high profitability that can improve the livelihood of fish farming households.

This paper proposed an approach to evaluate the economics of pumped-storage unit from the perspective of the power system. An MIP-based unit commitment model with multi-type units was established, which integrated thermal, CCGT, hydro, wind, nuclear and pumped-storage units. Based on the model the net present value of pumped-storage per megawatt was calculated and compared with the capital cost per megawatt, which produce the economic result of pumped-storage. The case study proved the feasibility of the above model and approach. Furthermore, the change of economic result of pumped-storage over system variables like nuclear capacity, wind capacity and regulating capacity of thermal unit was analyzed. The case study showed that with the increase of nuclear capacity, wind capacity and minimum output of thermal units, the economics of pumped-storage was improved.

The purpose of this case study is to conduct an economic analysis to calculate the proper terminal capacity of automated container terminal (ACT) investment from the perspective of the public sector. As a key element of smart port, the ACT is an important terminal operating facility for import/export and transshipment cargo between countries and must have facilities with sufficient capacity to load/unload export/import cargo in a timely manner according to the user’s request. Recently, the method of calculating the capacity of seaport infrastructure is changing from the method of applying the maximum capacity to the method of applying the proper capacity. Therefore, it is desirable to expand port facilities by investigating proper capacity rather than expanding port facilities based on the maximum performance. This study is a case study focusing on the new port of Busan introducing the ACT. From the perspective of national fiscal income and national economy from the ACT investment, this study determines the proper terminal capacity for each berth. As a result of economic analysis, the break-even terminal capacity to secure economic feasibility is from 544,272TEU of the nine berths to 600,138TEU of two berths applying a 2.96% discount ratio. In a sensitivity analysis considering the social discount rate and the change in the size of berths, the net present value has a positive value from a minimum of 530,000 TEU (nine berths with 1.96% social discount ratio) to a maximum of 620,000 TEU (three berths with 3.46% social discount ratio).

In many occasions severe water leakage problems are faced in shotcrete lined or unlined water tunnels that not only reduce stability of the rock mass but also result in loss of valuable water in conveying tunnel systems. Such leakage causes safety risks and increases the potential for huge economic loss to the hydropower projects. On the other hand, use of full concrete lining as final support increases the construction cost and time considerably. The best way to reduce leakage control and construction costs and time is the use of pre-injection grouting in the headrace tunnels. This paper discusses the role that post-injection grouting has played for controlling leakage through shotcrete lined/unlined low pressure headrace tunnel of the 60 MW Khimti I Hydropower Project in Nepal.
