In the article the author reveals the most significant methodological problems in this most important area, which is the basis for the reproduction of economic systems, on the basis of considering the most widely used methods of capital investment assessment. The article also provides a brief theoretical characterization of capital investments. It is concluded that the reason for methodological problems in the assessment of capital investments is the issue of the nature of capital, which has not been fully resolved in the field of fundamental economic theory. The author draws attention to the fact that the detailed methods of capital investment assessment for specific conditions of management of individual sectoral economic systems, elaborated in scientific articles, dissertations and other works, do not receive scientific generalization and balanced assessment of the community. In fact, it means that there are no methods proven and used by many researchers and practitioners. It is shown that it is inappropriate to completely identify the investment process, project appraisal and capital investments of enterprises. The author points out the gap between financial and technological efficiency existing in the theory and practice of work with investments. Further, using the example of the Russian electric power transmission industry, the author shows how general methods of capital investment assessment may not be applicable depending on specific industry conditions, and how theoretical and methodological problems in practice turn into a lack of tools for decision-making. In conclusion, based on the consideration of disproportions in the mechanism of capital investment assessment, implementation and regulation, another fundamental issue of the theory arises – the need to change approaches to the conflict of interests and regulation of natural monopolies as a non-cooperative game.

Since the planning of China's urban logistics system does not include end-of-line distribution in the unified planning, and less consideration is given to the cooperative distribution of multiple subjects, resulting in the overall low efficiency of the transportation link; at the same time, considering the impact of the epidemic on logistics distribution, "electric unmanned vehicles" with high efficiency, low cost and no contact characteristics become an important tool for end-of-line distribution. In summary, this paper takes the urban end distribution scenario as the research object, builds a cooperative distribution model among multiple subjects with electric unmanned vehicles as the carrier, and designs an improved algorithm to solve the model; finally, the optimization model proposed in this paper is verified through an example that it can give full play to the advantages of energy saving and emission reduction of electric unmanned vehicles and capital reduction compared with the traditional single distribution and single journey vehicle distribution model, thus promoting urban The model can be used to promote the green, low-carbon and sustainable development of the city.

The increasing demand for energy storage systems (ESSs) alongside the continuous enhancements to storage technology have been of great positive impact on the electric grid. Their unceasing development has been driven by the need to accommodate increased penetration of renewable energy resources and defer capital investments, among other benefits. Moreover, ESSs have played a key role in the grid’s ability to cope with its ever-shifting load profiles, resulting in large economic gain for ESS owners. For this reason, this prospective study was designed to investigate privately-owned energy storage hubs (ESHs) and their interactions with potential customers as well as with the electric grid. This research examined two contrasting interaction approaches for customer-owned stationary energy storage hubs: a cooperative and a non-cooperative game-theoretic approach. The goal of the cooperative technique is to conduce to a correlated equilibrium increasing the social welfare of all players involved using a regret matching algorithm. On the other hand, in the non-cooperative approach, modeled as an ascending price-clinching auction, each player acts greedily, maximizing only their individual welfare. Implementing both case studies resulted in important insights into ESH players’ interactions and provided contrasting methods of modeling their behaviors. Finally, depending on the application at hand, the choice of one approach may be more realistic than the other.

The Tokyo Electric Light Company, Inc., the largest electric power company in pre-war Japan, took an active merger policy and started accounting manipulations to maintain high dividends in the 1920’s. It, however, suffered extensive damage in 1923 when the Great Kanto Earthquake occurred and covered the damage by devising the appraisal profits of its fixed capital, which, though frequent in those days, constituted arbitrary accounting manipulations with no objective criteria. The Great Kanto Earthquake induced moral hazards to its management resulting in normalization of the accounting manipulations in the best interest of high dividends. Such accounting manipulations triggered the intervention of Mitsui Bank, Ltd. in its management, and partly contributed to the government control of electric power. As disasters are likely to show the inherent problems within companies, any temporary solution would instead result in more severe consequences.

The aim of this study is to ascertain how social system norms mediate the relationship between other exogenous variables and Nigerian civil servants' adoption of electric vehicles (EVs). It is a descriptive research design cross-sectional study. Data from a sample of 924 respondents in Abuja, Federal Capital Territory, was gathered through a survey. A 5-point Likert scale was used in the questionnaire's design. The study used structural equation model for data analysis after random sampling was employed to collect the data. The Statistical Package for Social Science (SPSS) and SmartPLS V4.0.9.5 were used to perform both descriptive and inferential statistics. The results indicate that social system norms have a positive and significant mediating function on perceived certainty, ease of use, knowledge, relative advantage, subjective norms, usefulness, and adoption of electric vehicles (EVs), with the exception of perceived compatibility with deviant relationships. We recommend that civil servants be encouraged by government policy to form cooperative societies so they can obtain financing for the purchase of electric vehicles at subsidised prices.

The COVID-19 pandemic has rapidly changed people’s lives, especially technological advancements. Most service industries have opted to adopt online payments since the pandemic happened. Electric utility companies are one of the major industries that utilize online payments as an alternative mode of payment to traditional cash payments to minimize person-to-person contact. The current study aimed to assess electric utility companies’ service quality and customer satisfaction to improve the payment system. The study was conducted in Occidental Mindoro Electric Cooperative, Inc. (OMECO), which utilized an online payment system due to COVID-19-protocol. The research model comprises 60 questionnaires with ten sections developed from the literature and distributed to 400 participants. The data were analyzed using the structural equation modeling and path analysis technique. The results showed that Online Payment Security had the most positive effect on service quality, thus affecting customer satisfaction. Moreover, tangibility, reliability, online payment method, and COVID-19-protocol positively affected service quality. While reliability, assurance, and empathy had a negative effect on the service quality of OMECO. Aligning with the result, OMECO was poorly evaluated by the participants in terms of empathy, assurance, responsiveness, and reliability. Moreover, the result of the study can be used by major electric companies to improve their service in terms of online payment. Finally, the current research is one of the first studies that integrate service quality and customer satisfaction while utilizing the structural modeling approach.

This article presents a close, dialogue-based ethnographic account of a group of contemporary options market makers making a decision about pricing options in Tesla, Inc. Careful attention to their deliberations reveals how the rise of algorithms and automation on financial markets have rendered traders alienated and estranged from the markets they work on for their livelihood. This alienation arises, in part, due to novel cascade effects between futures and underlying equities, which algorithmic and automated trading seems to afford, and which also relate to news events as well as the actions of politicians and prominent business people. Emerging from this alienation, traders produce a critique of how highly automated financial markets allocate capital and how ripe they are for political manipulation.

In recent years, there has been a shift in among Kentucky rural electric cooperatives in regard to their stance on economic development. With this has been the employment of electric cooperative staff to help attract new industries and forge relationships with other local economic development-geared groups to facilitate growth. Cooperative businesses have historically proved their resilience and deep-rooted connections within the communities they serve. In exploring two similar-sized electric cooperatives in Kentucky located in two very different regions of the state, considering socio-economic status, and interviewing key informants with local affiliated economic development groups, it becomes evident that electric cooperatives possess a great potential to serve as a catalyst for economic development within their respective service territories.

The development of Renewable Energy (RE) has become a major societal challenge. Even though RE technology is improving fast, the general public has been slow to adopt it. Meanwhile many RE cooperatives have been created; they act as social entrepreneurs in utilizing the social capital of a community to engage the public. Thus, the purpose of this chapter is to consider how they can contribute to the adoption of RE. The author uses an exploratory research design with a multiple case approach drawing on nine RE cooperatives. The chapter discusses a number of actions implemented by cooperatives in order to develop the adoption of RE. These are related to the diminishing of the RE costs, the use of educational campaigns, and the setting of RE projects at local level; the specific status of cooperatives is another facilitating factor. The author concludes by drawing future directions for research and stressing the cultural challenges for the RE cooperative model.

International city cooperation of sister city partnerships has become one of the important strategies to improve urban competitiveness, promote city development and urban development, as well as to create partnerships that can promote city agendas. Cities across the world have implemented or are implementing the concept of twinning, in which one urban local authority can partner with other local authorities in the world. Several studies have been done on international city cooperation especially in the European context. However, there is a paucity of knowledge on city twinning in Zimbabwe. This chapter seeks to examine the implications on local government operations through the twinning concept, using Harare and Munich as units of analysis. Overall, Harare has since twinned with Munich, in which the two cities cooperate in the areas of human capital development, capacity building, and information technology for cities. This development has seen Harare registering some improvements in terms of local government operations.

This research aims to analyse the situation in Maiduguri, capital of Borno State, northeastern Nigeria, one of the areas hardest hit by the violence perpetrated by the terrorist group Boko Haram, which has led to the forced displacement of thousands of people who have fled their homes to safer places such as camps for internally displaced persons or refugees. Using a qualitative methodology, within the interpretative paradigm, the aim is to find out whether actions are being developed to promote gender equality and equal opportunities, to analyse the degree of involvement and awareness of the community regarding the importance of gender equality and finally, and how we could contribute from international development cooperation to improve the situation of displaced women. Thanks to the needs assessment carried out in this research, it is possible to detect existing shortcomings and draw conclusions that will serve as a basis for the design of a proposal for social intervention aimed at achieving gender equality through the promotion of women's autonomy in the Maiduguri IDP camp.

This paper presents preliminary engineering results for a 50 MW Compressed Air Energy Storage (CAES) plant for the Alabama Electric Cooperative, Inc. (AEC). The CAES plant would improve AEC’s power generation mix in two ways: (a) it would provide needed peaking/intermediate power (otherwise purchased) and (b) it would increase the load factor of economical baseload units. The paper presents the following: a. Comparative trade-off analysis of various conceptual arrangements with underground storage depths ranging between 1000 feet and 4000 feet. (The most economical concept is selected based on the consideration of economics of the overall plant including underground storage). b. Engineering and cost data, performance data, construction schedule and environmental data for the selected CAES plant concept. The results of this preliminary engineering effort prove that a CAES plant is a cost effective addition to AEC’s installed power generation plants.

Abstract This study builds a decision support tool to evaluate when it is a good economic decision (least cost with minimum discomfort) for the residential customer to invest in distributed energy resources (DERs) based on different electricity rate structures, DER ownership frameworks, and DER rebates offered by electric utilities. The tool is demonstrated using empirical electricity consumption data from Pecan Street Inc. (a non-profit entity based on Austin, Texas), residential rates from Austin Energy (the municipal electric utility in Austin, Texas), DER ownership costs from various nationwide pilot programs, and incentives offered by electric utilities in the United States. Results show that for constant electricity rates, the overall expenditure is least when the customer owns solar panels without storage, while for time-varying pricing structures, the least expensive scenario is one where the customer does not own any DERs. As the capital costs for DERs decline, utilities incentivize customer ownership of DERs, and more residential customers face the decision of whether to invest in DERs, this study aims to be a key tool in aiding that decision-making process.

Future fossil-fueled power generation systems will require emission control technologies such as carbon capture and sequestration (CCS) to comply with government greenhouse gas regulations. The three prime candidate technologies which permit carbon dioxide (CO2) to be captured and safely stored include pre-combustion, post-combustion capture and oxy-fuel (O-F) combustion. For more than a decade Clean Energy Systems, Inc. (CES) has been designing and demonstrating enabling technologies for oxy-fuel power generation; specifically steam generators, hot gas expanders and reheat combustors. Recently CES has partnered with Florida Turbine Technologies, Inc. (FTT) and Siemens Energy, Inc. to develop and demonstrate turbomachinery systems compatible with the unique characteristics of oxy-fuel working fluids. The team has adopted an aggressive, but economically viable development approach to advance turbine technology towards early product realization. Goals include short-term, incremental advances in power plant efficiency and output while minimizing capital costs and cost of electricity. Phase 2 of this development work has been greatly enhanced by a cooperative agreement with the U.S. Department of Energy (DOE). Under this program the team will design, manufacture and test a commercial-scale intermediate-pressure turbine (IPT) to be used in industrial O-F power plants. These plants will use diverse fuels and be capable of capturing 99% of the produced CO2 at competitive cycle efficiencies and cost of electricity. Initial plants will burn natural gas and generate more than 200MWe with near-zero emissions. To reduce development cost and schedule an existing gas turbine engine will be adapted for use as a high-temperature O-F IPT. The necessary modifications include the replacement of the engine’s air compressor with a thrust balance system and altering the engine’s air-breathing combustion system into a steam reheating system using direct fuel and oxygen injection. Excellent progress has been made to date. FTT has completed the detailed design and issued manufacturing drawings to convert a Siemens SGT-900 to an oxy-fuel turbine (OFT). Siemens has received, disassembled and inspected an SGT-900 B12 and ordered all necessary new components for engine changeover. Meanwhile CES has been working to upgrade an existing test facility to support demonstration of a “simple” oxy-fuel power cycle. Low-power demonstration testing of the newly assembled OFT-900 is expected to commence in late 2012.

The U.S. Department of Energy (DOE) Office of Fossil Energy has established projects to develop highly efficient turbines for coal-based fuels in integrated gasification combined-cycle applications. These fuels include coal-derived synthesis gas and pure hydrogen. The projects, with both General Electric and Siemens, have specific performance goals they must strive to attain. In order to ascertain the actual performance improvements that must be realized in these projects to reach the project goals, existing turbine baseline performance must be established. This paper will present the work conducted to establish the baseline performance parameters, and the values of these parameters. Performance parameters and values reported in the open literature will be presented. Parameters that are not available in the literature are also reported and were obtained by using ASPEN PLUS (Aspen Technology, Inc.) and GT-PRO (Thermoflow, Inc.) simulation software. A survey was conducted to obtain available process conditions and parameters related to Simple-Cycle (SC) and Combined-Cycle (CC) gas turbine performance in integrated gasification combined-cycle (IGCC) applications that use coal as the primary fuel source. Information sources include commercial IGCC plants funded through the Clean Coal Technology (CCT) Demonstration Program, a proposed greenfield IGCC plant, NETL system studies, and other open literature sources. The report results can be employed to assist DOE in establishing a “Baseline IGCC Plant Performance Model” for comparisons with future improvements. The year 2010 IGCC performance goals include 45-50% HHV efficiency, $1,000 / kW total capital costs, and near-zero emissions. Contributions toward this goal are provided by DOE’s Gasification and Advanced Turbines programs. Contributions from the Turbines program are targeted to provide 2-3 percentage points improvement in combined-cycle performance by 2010 for synthesis gas applications, and 3-5 percentage points (total) by 2015 for hydrogen fuels. The results are summarized in a series of tables that highlight the information identified that includes gas turbine type, turbine simple-cycle and combined-cycle efficiencies, turbine temperatures (e.g., firing temperature, exhaust temperature), pressure ratio, diluents, fuel composition, ASU integration, coal analysis, emissions, and the overall plant efficiency. The turbines and plants assessed to determine this baseline performance included the U.S.-based GE 7F frame turbines at the Wabash IGCC, Tampa IGCC, and Ashtabula IGCC (Nordic Energy - proposed 2002, Ashtabula, Ohio), as well as two European IGCC plants based on Siemens-Westinghouse V94.2 / V94.3 frame turbines located at the Buggenum IGCC (Netherlands) and Puertollano IGCC (Spain).

Since 1984, TEPCO (Tokyo Electric Power Co., Inc.) has been conducting a cooperative research program to apply ceramics to power generating gas turbines with three Japanese gas turbine manufacturers (Toshiba Corporation, Mitsubishi Heavy Industries, Ltd., and Hitachi, Ltd.). The goal of the program is development of a 20MW class gas turbine with turbine inlet temperature of 1,300C (1,573K) to improve the efficiency of coal gasification combined cycle power generation. Preliminary design of the gas turbine was conducted during 1984–1985 and basic design criteria, such as desired configuration and material properties, were established. Based on the results of the preliminary design, it was decided to apply ceramics to the liner and transition piece of the combustor, the 1st and 2nd stage nozzles and 1st stage rotor in a three stage turbine. As for the rotors, development efforts were also applied to thermal barrier coatings on conventional metal blades. Parallel efforts have been conducted on the development of each ceramic component since 1986. This paper will review the design of ceramic components from structural and material standpoints, and present results obtained from tests conducted under various operational conditions.

Alfalfa processing facilities separate the fibrous stem material from the protein-rich leaf fraction. The resulting alfalfa leaf meal (ALM) is further processed into a variety of valuable livestock feed products. Alfalfa stem material is gasified using air-blown fluidized bed technology to produce a hot, clean, fuel gas. The fuel gas is fired in a combustion turbine and the exhaust heat is used to produce steam to power a steam turbine. At base load, the electric power plant will consume 1000 tons per day of biomass fuel. This paper briefly describes the project development activities of the alfalfa feed trials and the combined cycle power plant. This commercial scale demonstration represents an important milestone on a continuing pathway towards environmentally and economically sustainable energy systems.

Future fossil-fuel-based power generation systems must include decarbonizing technologies to capture and store (CCS) carbon dioxide (CO2). Oxy-fuel (O-F) combustion-based power systems are uniquely capable of capturing almost all CO2. In the O-F power plant cycle, fuel and nearly pure oxygen, delivered from an air separation unit (ASU), are burned to form a working fluid composed primarily of steam and CO2. Clean Energy Systems (CES), Siemens Energy, Inc. and Florida Turbine Technologies, Inc. (FIT) are jointly developing turbomachinery systems driven by O-F working fluids and have adopted a stepped development approach to advance the technology toward product realization through an initial proof-of-concept phase and subsequent development of 1st and 2nd generation power plant systems. Specific goals and objectives target incremental advancements of power plant efficiency and output while reducing capital costs and cost of electricity. In the initial proof-of-concept phase, bench-level research was performed on a primary combustion system. A 20MWth development gas generator was used to explore operability and performance limits while operating on a variety of fuels over a wide range of conditions. Further, the working fluid produced by this combustor was used to drive an existing turbine/generator set at CES’ Kimberlina prototype power plant located near Bakersfield, California. This paper summarizes the recent follow-on work to develop and demonstrate 1st and 2nd generation O-F power plant systems. Successful completion of the proof-of-concept phase led to the development of the 1st generation power plant system. Specific equipment required for this operation included a larger 170MWth combustor, which was constructed to produce additional power in this phase. An existing General Electric GE-J79 turbine was modified to extract power from this unit. All equipment required for this system has been assembled at CES’ Kimberlina power plant. In addition, a reheat combustion system is being developed to enhance the 1st generation power plant cycle. In a logical next step, a larger power output, increased-efficiency 2nd generation power plant system was defined. For this application, the Siemens SGT-900 gas turbine was selected as the basis for the Intermediate Pressure Turbine. Conceptual design studies were performed to identify the modifications needed in order to adapt the hardware to accept O-F drive gases. Specific challenges related to the mechanical design configuration, and thermal/structural behaviors of the system are delineated. Testing is being performed to characterize the behavior of materials when exposed to the steam/CO2 working fluid environment. Necessary development of long-lead items required for this system is also described.

To cope with the increasing demand of electric power, many research and development programs have been performed in the field of electric power industry. Among them, the application of highly thermal resistive ceramics to hot parts of the gas turbines is one of the most promising ways to raise the thermal efficiency of the gas turbine, and several projects have been executed in the U.S.A., Europe and Japan. Tokyo Electric Power Co., Inc. (TEPCO) also has been conducting a research project to apply ceramic components to hot parts of a 20MW class gas turbine with a turbine inlet temperature of 1300C. In this project. TEPCO and Hitachi have been conducting the cooperative research work to develop a first stage ceramic rotor blade. After several design modifications, it was decided to select ceramic blades attached directly to a metal rotor disc, and to insert metal pads between the dovetail of the ceramic blade and metal disc to convey the centrifugal force produced by the blade smoothly to the metal disc. The strength of this ceramic blade has been verified by a series of experiments such as tensile tests, room temperature spin tests, thermal loading tests, and high temperature spin tests using a high temperature gas turbine development unit (HTDU). In addition, the reliability of the ceramic blade under design and test conditions has been analyzed by a computer program GFICES (Gas turbine - Fine Ceramics Evaluation System) which was developed on the basis of statistical strength theory using two parameter Weibull probability distribution. These experiments and analyses demonstrate the integrity of the developed ceramic rotor blade.

A program has been underway since 1986 by Westinghouse Electric Corporation, Textron, Inc., and the sponsoring agency, the Morgantown Energy Technology Center (METC) of the U.S. Department of Energy (DOE), as participants, to establish the technology base for coal-fired combustion turbines targeted for power generation (50 to 150 MW size units). The developed system must be able to burn unbeneficiated, low-cost, utility-grade coal and meet the EPA New Source Performance Standards (NSPS) for coal-fired steam generators (Thoman et al., 1987). Development of a high pressure (12 to 16 atms) slagging combustor is the key to making a direct coal-fired combustion turbine a commercial reality. In testing to date, a 6 atm slagging combustor, rated at 12 MMBtu/hr (12.7 MHkJ/hr) has demonstrated its ability to handle high- and low-sulfur bituminous coals, and low-sulfur subbituminous coal. The program objectives relative to combustion efficiency, combustor exit temperature and pattern factor, NOx emissions, carbon burnout, and slag rejection have been met. Today, Northern States Power, working with Westinghouse with assistance from Textron is developing a plan to commercialize a direct coal-fired advanced combined cycle (DCFACC). Included in this plan is a pilot plant (which does not include a combustion turbine) and a demonstration plant that would utilize a 50 MW combustion turbine. The first commercial DCFACC, which would Include a 100 MW combustion turbine, is scheduled to be operational by the year 2001. The cooperative effort among Northern States Power, Westinghouse, and Textron is financially independent of the work now sponsored by DOE/METC. This paper presents the status of the pressurized slagging combustor development program including recent work to reduce alkali, particulates and SOx levels leaving the combustor and gives an overview of our commercialization process and plan.
