Abstract. Vertical hollow shaft motors are commonly used for vertical turbine pumps for irrigation. They are a specialty motor which has been exempt from the Department of Energy (DOE) requirement for improved energy efficiency. We evaluated the payback and net present value (NPV) of standard efficiency, energy efficient, and premium efficiency motors for motor sizes used in irrigation. For motor sizes between 22 and 56 kW (30 and 75 hp), the NPV and payback analysis indicated that premium efficient motors are more advantageous than standard efficiency. In motor sizes greater than 75 kW (100 hp) standard efficient motors are more cost effective than replacing a motor with a premium efficiency motor. When considering a repair or rewind of a motor, the result is highly dependent on the quality, and the resulting efficiency expected after the repair. If a repaired motor nameplate efficiency could be attained after rewinding and repair, then rewinding is most cost effective. However, if original nameplate efficiency is not attained, then it may be more cost effective to purchase a premium efficiency motor over rewinding. New DOE requirements may be advantageous for irrigators even though capital costs will be higher for new motors. Keywords: Motor rewind, Net present value (NPV), Payback period, Premium efficiency motor.

The Cost

In this article the technique of determination of payback period of investments taking into account capital costs and economy of means at the expense of implementation of energy saving actions for warming of external protecting designs is considered. Presented in the article the method of assessing the return on investment in the implementation of energy-efficient solutions of facade insulation is only evaluative. For more accurate calculations it is necessary to take into account the discount rate. Nevertheless, the main factors that have a positive impact on reducing the payback period of investments in the renovation of facades are identified. Only an integrated approach to improving the energy efficiency of buildings can not only reduce the cost of operation of buildings, but also provide a reduction in the payback period of investment in the implementation of energy efficiency measures.

An economic study for the photovoltaic (PV) projects by the PV installer is essential to avoid the risk that may incur from the investment. This paper discusses the economic analysis of PV installations specifically for the grid connected (GC) systems. The case study is the 9 kW Solar-Home UTM system which is planned to be a showcase GC zero energy house. The house will be able to sell the excess energy back to the grid according to the Malaysian Feed-in Tariff (FiT) implemented in 2012. The economic study conducted is based on the Net Present Value (NPV) and the Pay-Back Period to determine the profitability and viability of the project. The study is believed to encourage and initiate the public to build a successful investment and contribute in the development and deployment of new clean energy sources.

Steam turbine cogeneration analysis (STuCA) is a quasi-static steam cogneration plant modelling tool, which has been developed and applied to the Auckland Hospital energy centre at Auckland, New Zealand. The STuCA code consists of four submodels, namely a load, a system, a plant and an economic model. The load model was developed using historical data and drove the system model, which consisted of heat exchangers. The system model output was then used to drive the plant model that modelled the turbine and boiler and predicted the primary energy flows and cash flows at the site. Economic analysis tools including thermodynamic, thermoeconomic and economic performance measures such as the payback period and the net present value used these data to analyse the economic performance measures such as the payback period and the net present value used these data to analyse the economic performance of the site. The STuCA model output correlated to site data to within 10 per cent and provided data that could be used by the economic analysis tools. The application of the STuCA model to the hospital site proved that it could be used to design cogeneration plants, to analyse retrofit, to upgrade proposals and to study the effects of changing site loads on plant performance.

This paper presents the results of the technological and economic analysis of mine water treatment systems before their discharge into the environment. The following analysis enabled us to determine the profitability of the investment, taking into account the TSS (total suspended solids) concentration in mine water. The simulation results showed that it is economically profitable to apply a water treatment system if natural sedimentation carried out in underground mine water passages, or in sedimentation tanks located on the ground, is ineffective for TSS removal. Economic and financial parameters allow us to conclude that all analyzed variants of the application of a pre-treatment system are characterized by high economic effectiveness. This mainly results from the high profitability of an analyzed investment, comparatively low capital expenditure, and present low market percentage rates. The most profitable variant (TSS concentration is 1000 mg/dm3) brings significant economic indicators, i.e., high NPV–Net Present Value (100 319 270.28 PLN), a high NPVR–Net Present Value Ratio (8.96 PLN/PLN), and a short discount payback period (1 year 236.6 days). A high internal rate of return (157.8%) for this variant reduces the risk of losing profitability in a situation of growing capital costs in the monetary market.

The fish shelter port (TPI) is a need that needs to be prepared by local village officials and the government for every coastal village in Bengkalis Regency. This research was conducted in the Berancah village of Bantan District. The analysis in this study describes the economic feasibility mathematically for the construction of a fish storage port (TPI) by calculating the cost ratio (B / C ratio) benefit analysis, payback period (PP), net present value (NPV), and internal rate of return ( IRR). The results obtained from the NPV value (3,661,267,645), BCR value (0.943), IRR value of 10.01%, and PP are in the period of 30 years. Taken as a whole by standardizing the calculations, it can be concluded that the planned construction of a fish shelter in Berancah village is considered not economically feasible, but economic analysis is not merely a benchmark for feasibility, reviewed for the future many benefits will be received by the community around the location of the development plan so that it can improve the welfare of the community in Berancah village.
