Full textAbstract:
Many important issues in modern Chinese history are crucially affected by the magnitude and pattern of economic growth up to 1937. Despite the work of John Key Chang and more recently Thomas Rawski, however, we still know all too little about the quantitative aspects of that growth. All scholars of the period are greatly indebtedto Chang's pioneering and indispensame work on industrial production but, as he himself points out, his index remains tentative and exploratory. Although the compilation of a definitive new index will eventually depend on work by scholars in China, to my knowledge this has not yet got under way. Wherever compiled, any index of industrial output as a whole, or even of national income, will have to be based on better series for individual industries. In such a context, this research note builds on Chang's work by offering a revision of the output series for one very important and rapidly growing industry in pre-1937 China, the electric power industry.

Technical and economic aspects of synthetic liquid fuel and electric power combined production within one energy-technology installation (ETI) are considered. The range of prices for alternative liquid fuel (ALF) produced by the installations, depending on the cost of consumed fuel, price of supplied electric power and level of capital investments, has been ascertained. The studies made suggest the conclusion that combined production of dimethyl ether is more efficient from the energy and economic viewpoints than methanol production. Besides, a certain level of oil prices was identified, its excess implying that production of ALF, i.e. dimethyl ether, will be more economically efficient than production of motor fuel from oil.

A deterministic quantitative model has been developed to compare the technical, economical and environmental feature of various electric power generating plants. The model, which is based on matrix operations, is used in evaluating the various aspects of energy sources available for electricity generation systems in a developing country. Several energy sources which could be considered for production of electricity to meet current and future electricity demands have been chosen. These will include fossil fuel fired, nuclear, and natural-renewable energy power plants. And, a set of criteria for optimized selection includes five area of concerns: energy economy, energy security, environmental protection, socio-economic development and technological aspects for the electric power generations. The model developed in this study is applied to the Indonesian’s electric power sector development. Most of the data required are obtained from various sources related to power industry in Indonesia, such as the electricity generating authority of Indonesia (Perusahaan Listrik Negara, PLN), Government of Indonesia, World Bank, Asian Development Bank, United Nations, and other sources, both in published and public domains. The result of this study will be a ranking of energy sources for Indonesia power generation systems based on the Euclidean composite distance of each alternative to the designated optimal source of energy.

The research considers various aspects of electric vehicle production in some leading foreign countries. Dynamics of specific weight of electric vehicles in total transport and its forecast indices are under analysis considering those of the countries planning complete transition to electric mobility. Urgency of building an expanded network of charging stations of various capacity is pointed out. It is revealed that Volkswagen, the world largest automobile concern, is going to introduce much more new designs of electric vehicles than it considered before – 70 instead of 50 by 2028. It is planned to produce more electric vehicles – from 15 to 22mln in the decade to follow. Besides, the share of electric vehicles in the concern’s total production is to exceed 40% by 2030. It is indicated that 44bln euros will be invested into designing new VW automobiles in the nearest 5 years. It is significant that in many foreign countries there are subsidies and tax reduction for electric vehicle owners which are used as an important tool of the state’ incentives. Besides, special attention is paid to improvement and development of production of batteries for electric cars, especially in the EU countries. The authors suggest schemes of elaborating electric mobile innovations and power supply for electric mobility providing green and economic solutions for generating power for electric cars by wind generators. Potential production of Ukrainian electric cars is under analysis. It is highlighted that electric vehicle production allows combining two economically beneficial factors – innovative character of a product and its large-scale production. In this case, there will be a novelty effect and huge unsatisfied demand as well as scale saving.

Increasing economic importance of the Arctic, further intensification of northern sea routes, and exceptional sensitivity of the arctic natural environment to anthropogenic impacts are fundamental factors for a comprehensive study of environmental aspects in the application of innovative technologies for the development of infrastructure in the Arctic. Despite the growing interest in low-power nuclear power plants as a distributed generation facility, their possible application in technologically isolated power systems does not lose relevance. The development of both the Arctic and Far Eastern regions of the Russian Federation presents great opportunities and demand for the use of nuclear power sources. Also, development programs for the Russian arctic zone imply a significant increase in the role and number of nuclear power facilities, in other words of potential radiation-hazardous facilities. Large-scale use of nuclear-powered installations in the Arctic necessitates advanced development of a scientifically grounded and modern forecasting system as well as assessments of threats and risks in case of possible radiation emergencies at nuclear- and radiation-hazardous facilities. Also, the development of proposals for necessary measures to minimize negative consequences of such emergencies is required. This is especially true for the case of compact placement of industrial, infrastructure and residential facilities in the Arctic in the immediate vicinity of nuclear facilities. The paper demonstrates that the demand for low-power nuclear power plants and their competitiveness will grow steadily in the conditions of electric-power industry decentralization, further spread of distributed generation and the development of technologically isolated power systems. Approaches to the generation of a low nuclear-power system based on the philosophy of industrialization of production and centralized management are presented. Special features of the environmental impact assessment of low-power nuclear power plants for the development of a methodology to study the radio-ecological hazard related problems are provided.

Full textAbstract:
The development of the power sector is required to consider not only the environmental factors but also the economic and security factors. Management of electrical energy in Indonesia faced a major problem because of the shortage of energy production demand continues to increase 7.1% annually and the energy production is also very depending on fossil energy sources which dominate 85% of the total power generation. This condition will lead to increasing gas emissions in greenhouse by 78.01 million tons per year. Evaluation of existing plants with a dynamic model of the system will be a consideration for the sustainability of hydropower operation. The simulation results of the Sutami HEPP show more economical and more eco-friendly than fossil energy-based power plant. It is important to build and maintain a HEPP in Indonesia today, due to the potential based on these considerations, the capacity and the reduction of greenhouse gas emissions.

Full textAbstract:
Climate change is one of the major problems that people face in this century, with fossil fuel combustion engines being huge contributors. Currently, the battery powered electric vehicle is considered the predecessor, while hydrogen vehicles only have an insignificant market share. To evaluate if this is justified, different hydrogen power train technologies are analyzed and compared to the battery powered electric vehicle. Even though most research focuses on the hydrogen fuel cells, it is shown that, despite the lower efficiency, the often-neglected hydrogen combustion engine could be the right solution for transitioning away from fossil fuels. This is mainly due to the lower costs and possibility of the use of existing manufacturing infrastructure. To achieve a similar level of refueling comfort as with the battery powered electric vehicle, the economic and technological aspects of the local small-scale hydrogen production are being investigated. Due to the low efficiency and high prices for the required components, this domestically produced hydrogen cannot compete with hydrogen produced from fossil fuels on a larger scale.

Full textAbstract:
Meeting the increasing global energy demand in a sustainable way is a major challenge for humanity. One of the solutions in the transportation sector is ethanol, which is currently the only economically viable direct fuel substitute. In addition to the first-generation technology, which provides the vast majority of production, better results can be continuously realized by using advanced technologies. This study aims to investigate the economic aspects and sustainability issues of ethanol production with a systematic literature review. During the selection process, 64 studies from a total of 16,141 identified articles were analyzed in-depth. There is a consensus that first-generation production methods cannot result in a long-term solution. However, advanced technologies are currently immature, and ethanol production is more expensive with them. The use of wastes/residues and coproducts can improve both the economic outlook and sustainability of the advanced technologies. Overall, the newer generations of technological advancements are constantly improving the environmental performance, whereas the economic performance is deteriorating. Considering low oil prices (0.36 USD/L), none of the ethanol production methods can be competitive on a purely cost basis. This increases the importance of coproducts (further processing and more valuable coproducts). Regarding sustainability, a complex analysis is essential, which must cover at least the environmental, social, and economic aspects. At the methodology level, a complex life cycle analysis seems to be the best tool, as it can take into account these relevant aspects (environmental, economic, and social).

Full textAbstract:
The use of electricity in 21st century living has been firmly established throughout most of the world, correspondingly the infrastructure for production and delivery of electricity to consumers has matured and stabilised. However, due to recent technical and environmental–political developments, the electricity infrastructure worldwide is undergoing major restructuring. The forces driving this reorganisation are a complex interplay of technical, environmental, economic and political factors. The general trend of the reorganisation is a dis–aggregation of the previously integrated functions of generation, transmission and distribution, together with the establishment of competitive markets, primarily in generation, to replace previous regulated monopolistic utilities. To ensure reliable and cost effective electricity supply to consumers it is necessary to have an accurate picture of the expected generation in terms of the spatial and temporal distribution of prices and volumes. Previously this information was obtained by the regulated utility using technical studies such as centrally planned unit–commitment and economic–dispatch. However, in the new deregulated market environment such studies have diminished applicability and limited accuracy since generation assets are generally autonomous and subject to market forces. With generation outcomes governed by market mechanisms, to have an accurate picture of expected generation in the new electricity supply industry, it is necessary to complement traditional studies with new studies of market equilibrium and stability. Models and solution methods have been developed and refined for many markets, however they cannot be directly applied to the generation market due to the unique nature of electricity, having high inelastic demand, low storage capability and distinct transportation requirements. Intensive effort is underway to formulate solutions and models that specifically reflect the unique characteristics of the generation market. Various models have been proposed including game theory, stochastic and agent–based systems. Similarly there is a diverse range of solution methods including, Monte–Carlo simulations, linear–complimentary and quadratic programming. These approaches have varying degrees of generality, robustness and accuracy, some being better in certain aspects but weaker in others. This thesis formulates a new general model for the generation market based on the Cournot game, it makes no conjectures about producers’ behaviour and assumes that all electricity produced is immediately consumed. The new formulation characterises producers purely by their cost curves, which is only required to be piece–wise differentiable, and allows consumers’ characteristics to remain unspecified. The formulation can determine dynamic equilibrium and multiple equilibria of markets with single and multiple consumers and producers. Additionally stability concepts for the new market equilibrium is also developed to provide discrimination for dynamic equilibrium and to enable the structural stability of the market to be assessed. Solutions of the new formulation are evaluated by the use of evolutionary computation, which is a guided stochastic search paradigm that mimics the operation of biological evolution to iteratively produce a population of solutions. Evolutionary computation is employed as it is adept at finding multiple solutions for underconstrained systems, such as that of the new market formulation. Various enhancements to significantly improve the performance of the algorithms and simplify its application are developed. The concept of convergence potential of a population is introduced together with a system for the controlled extraction of such potential to accelerate the algorithm’s convergence and improve its accuracy and robustness. A new constraint handling technique for linear constraints that preserves the solution’s diversity is also presented together with a coevolutionary solution method for the multiple consumers and producers market. To illustrate the new electricity market formulation and its evolutionary computation solution methods, the equilibrium and stability of a test market with one consumer and thirteen thermal generators with valve point losses is examined. The case of a multiple consumer market is not simulated, though the formulation and solution methods for this case is included. The market solutions obtained not only confirms previous findings thus validating the new approach, but also includes new results yet to be verified by future studies. Techniques for market designers, regulators and other system planners in utilising the new market solutions are also given. In summary, the market formulation and solution method developed shows great promise in determining expected generation in a deregulated environment.

Thesis (MBA)--Stellenbosch University, 2011.Gaia Power is a South African start-up in the renewable energy industry. Among other products, they developed a wave energy converter, which is a device used to extract energy from ocean waves. This research deals with the economic feasibility study of the wave energy converter. Wave energy is a young field of research, especially in the South African context. Therefore sources for multiple angles of the project had to be found, analysed and brought into the Gaia Power context. Understanding the cost drivers of a wave energy plant was the foundation of the research itself. The Gaia Power specific levelised cost of electricity generation was calculated based on actual supplier quotes, reference costs found in the literature as well as assumptions. Still, such a calculation is actually more an estimation due to a high uncertainty level in all cost components. Especially the construction cost as well as the discount rate used have therefore been tested for sensitivity. Gaia Power‟s target production cost was R0.54 kWh, which equalled the Eskom tariff at the time of this research. Taking into account a R0.10/kWh fee payable to Eskom, the target cost sank to R0.44, which is about 25 percent lower than the minimum value for electricity generation cost found in the literature. This target was therefore expected to be and proved to be difficult to reach. The calculated levelised electricity cost was R0.99/kWh, with a possible range of R0.54/kWh to R1.60/kWh observed in the sensitivity analysis. These results show that the Gaia Power wave energy converter in the given specifications was not economically feasible. It was therefore recommended to rethink the specifications in order to reduce construction cost, which proved to be the largest cost driver. Besides the quantitative findings, this research also has a strong qualitative side. During the whole research it became obvious that there was an overall high risk level in the project due to the lack of experience with wave energy in general and in South Africa specifically, as well as the high impact of weather on the construction. Those risks were identified, analysed and recommended mitigation actions were derived.

Ötsch, Rainald. "Stromerzeugung in Deutschland unter den Rahmenbedingungen von Klimapolitik und liberalisiertem Strommarkt : Bewertung von Kraftwerksinvestitionen mit Bayes’schen Einflussdiagrammen." Phd thesis, Universität Potsdam, 2012. http://opus.kobv.de/ubp/volltexte/2014/6905/.
Full textAbstract:
Mit der Liberalisierung des Strommarkts, den unsicheren Aussichten in der Klimapolitik und stark schwankenden Preisen bei Brennstoffen, Emissionsrechten und Kraftwerkskomponenten hat bei Kraftwerksinvestitionen das Risikomanagement an Bedeutung gewonnen. Dies äußert sich im vermehrten Einsatz probabilistischer Verfahren. Insbesondere bei regulativen Risiken liefert der klassische, häufigkeitsbasierte Wahrscheinlichkeitsbegriff aber keine Handhabe zur Risikoquantifizierung. In dieser Arbeit werden Kraftwerksinvestitionen und -portfolien in Deutschland mit Methoden des Bayes'schen Risikomanagements bewertet. Die Bayes'sche Denkschule begreift Wahrscheinlichkeit als persönliches Maß für Unsicherheit. Wahrscheinlichkeiten können auch ohne statistische Datenanalyse allein mit Expertenbefragungen gewonnen werden.
Das Zusammenwirken unsicherer Werttreiber wurde mit einem probabilistischen DCF-Modell (Discounted Cash Flow-Modell) spezifiziert und in ein Einflussdiagramm mit etwa 1200 Objekten umgesetzt. Da der Überwälzungsgrad von Brennstoff- und CO2-Kosten und damit die Höhe der von den Kraftwerken erwirtschafteten Deckungsbeiträge im Wettbewerb bestimmt werden, reicht eine einzelwirtschaftliche Betrachtung der Kraftwerke nicht aus. Strompreise und Auslastungen werden mit Heuristiken anhand der individuellen Position der Kraftwerke in der Merit Order bestimmt, d.h. anhand der nach kurzfristigen Grenzkosten gestaffelten Einsatzreihenfolge. Dazu wurden 113 thermische Großkraftwerke aus Deutschland in einer Merit Order vereinigt. Das Modell liefert Wahrscheinlichkeitsverteilungen für zentrale Größen wie Kapitalwerte von Bestandsportfolien sowie Stromgestehungskosten und Kapitalwerte von Einzelinvestitionen (Steinkohle- und Braunkohlekraftwerke mit und ohne CO2-Abscheidung sowie GuD-Kraftwerke).
Der Wert der Bestandsportfolien von RWE, E.ON, EnBW und Vattenfall wird primär durch die Beiträge der Braunkohle- und Atomkraftwerke bestimmt. Erstaunlicherweise schlägt sich der Emissionshandel nicht in Verlusten nieder. Dies liegt einerseits an den Zusatzgewinnen der Atomkraftwerke, andererseits an den bis 2012 gratis zugeteilten Emissionsrechten, welche hohe Windfall-Profite generieren. Dadurch erweist sich der Emissionshandel in seiner konkreten Ausgestaltung insgesamt als gewinnbringendes Geschäft. Über die Restlaufzeit der Bestandskraftwerke resultiert ab 2008 aus der Einführung des Emissionshandels ein Barwertvorteil von insgesamt 8,6 Mrd. €. In ähnlicher Dimension liegen die Barwertvorteile aus der 2009 von der Bundesregierung in Aussicht gestellten Laufzeitverlängerung für Atomkraftwerke. Bei einer achtjährigen Laufzeitverlängerung ergäben sich je nach CO2-Preisniveau Barwertvorteile von 8 bis 15 Mrd. €. Mit höheren CO2-Preisen und Laufzeitverlängerungen von bis zu 28 Jahren würden 25 Mrd. € oder mehr zusätzlich anfallen.
Langfristig erscheint fraglich, ob unter dem gegenwärtigen Marktdesign noch Anreize für Investitionen in fossile Kraftwerke gegeben sind. Zu Beginn der NAP 2-Periode noch rentable Investitionen in Braunkohle- und GuD-Kraftwerke werden mit der auslaufenden Gratiszuteilung von Emissionsrechten zunehmend unrentabler. Die Rentabilität wird durch Strommarkteffekte der erneuerbaren Energien und ausscheidender alter Gas- und Ölkraftwerke stetig weiter untergraben. Steinkohlekraftwerke erweisen sich selbst mit anfänglicher Gratiszuteilung als riskante Investition.
Die festgestellten Anreizprobleme für Neuinvestitionen sollten jedoch nicht dem Emissionshandel zugeschrieben werden, sondern resultieren aus den an Grenzkosten orientierten Strompreisen. Das Anreizproblem ist allerdings bei moderaten CO2-Preisen am größten. Es gilt auch für Kraftwerke mit CO2-Abscheidung: Obwohl die erwarteten Vermeidungskosten für CCS-Kraftwerke gegenüber konventionellen Kohlekraftwerken im Jahr 2025 auf 25 €/t CO2 (Braunkohle) bzw. 38,5 €/t CO2 (Steinkohle) geschätzt werden, wird ihr Bau erst ab CO2-Preisen von 50 bzw. 77 €/t CO2 rentabel.
Ob und welche Kraftwerksinvestitionen sich langfristig rechnen, wird letztlich aber politisch entschieden und ist selbst unter stark idealisierten Bedingungen kaum vorhersagbar.Power plant investors face large uncertainties due to ongoing liberalization, climate policy, and long investment horizons. This study provides a probabilistic appraisal of power plant investments within the framework of Bayesian decision theory. A Bayesian influence diagram is used for setting up a discounted cash flow model and analysing the profitability of power plants. As the study explicitly models merit order pricing, the pass-through of random fuel and carbon costs may be analysed. The study derives probabilistic statements about net present values of single investments and company portfolios and explores the sensitivity of profits to variations of select input variables. In the majority of cases, an increase in the price of emission allowances also increases the net present value of existing power plant portfolios. A substantially increased carbon prices also is the prerequisite to diversify power plant portfolios by gas and CCS plants. For the currently prevailing German electricity market, we argue that investors may lack incentives for new investments in fossil generation, a finding that holds true also with implementation of CCS. Our estimates are conservative, as profitability will further deteriorate with the build-up of renewables.

Full textAbstract:
The dissertation uses the lens of electricity provision to examine processes of state formation in Somaliland, an unrecognized, self-declared independent state in the northwest of the former Somali Republic. The dissertation focuses on Hargeisa, the capital city at the heart of Somaliland's state-building project. After the collapse of the Somali state in 1991, private companies arose from the ruins of Hargeisa and turned the lights back on, navigating a fragmented post-war landscape by mobilizing local connections and transnational ties. However, being dependent on the political settlement that engendered the peace necessary for business, emerging private power providers were tied into a state-building project. The dissertation analyses the resulting tensions at the heart of this project, by examining the struggle to define the role, extents and limits of an emerging state in an interconnected world. Based on interviews in Somaliland and a survey of news media and grey literature, the dissertation has three aims. First, it provides a view into how social order and service provision persist after the collapse of the state. Secondly, it investigates how patterns of provision emerging in the absence of the state shape subsequent processes of state formation. Finally, it discusses how patterns of provision affect the interaction of state-building and market-making. In order to fulfil these aims, the dissertation examines how people invest in the project of building a state, both materially and discursively. The chapters present a narrative history of the electricity sector, explaining the attempts of both private companies and the government to claim sovereignty over the market and shape statehood in their own interests. The struggles shaping Somaliland's economic order reveal the contemporary significance of transnational connections, interconnected systems of capital flows, and the rise of corporate business actors. At the same time, they underline the abiding power of social structure, local identities, and historical memory.

Awarded by:University of New South Wales. School of Electrical Engineering & Telecommunications, 2005. http://handle.unsw.edu.au/1959.4/20834.
Full textAbstract:
The restructuring of many national and state electricity industries over the last two decades has created new sets of laws and regulations, market design and participants. Along with those changes, industry risks have also been transformed significantly. Prior to restructuring, government-owned or carefully regulated monopoly private utilities would manage most of these industry risks. With restructuring, however, both the government, through their market regulators, and industry participants need to manage a range of previous,, yet also now new, risks. While the government???s risk management strategy is focused on the industry as a whole, participants are naturally more concerned with their individual risks. The Australian National Electricity Market (NEM) is one of the many electricity markets that were formed through the restructuring process underway worldwide. It created a number of new types of market participants facing different sets of risks. The main objective of this thesis is to examine the management of market risk by these different NEM participants. The methodology used in the thesis involves developing a fundamental understanding of electricity restructuring, the NEM and the various risks faced by the different NEM participants. Data on NEM spot prices, ancillary costs and forward prices are analysed to gain a better understanding of its relationship with market activities. Different risk management strategies, both proactive and reactive, that can be taken by the participants are discussed This thesis has highlighted some of the complexities involved in managing risks in a restructured electricity industry. Risks are never static and changes in market conditions alter the risk exposure of the participants. Therefore, participants will need to constantly monitor their risk exposure and update their risk management strategies. The Cash-Flow-at-Risk methodology is introduced as a possible tool to measure risk and analyse risk management options for different NEM participants.

AbstractClimate change contributes significantly to the looming food insecurity in the rain-fed agricultural countries of Africa, including Nigeria. There is a gender dimension in climate change impacts and adaptation strategies along Agriculture Value Chain (AVC) in Nigeria. The chapter gender analyzed the aspects of climate change impacts; identified the indigenous and expert-based artificial adaptation strategies; assessed the gender differences in the adaptation strategies; and provided the gender implications of the indigenous adaptation strategies among actors along the AVC. The chapter adopted a value chain-based exploratory design with gender analysis as the narrative framework with Gender Response Theory as the theoretical background. There were gender differences in the production, economic, and social dimensions of the climate change impacts along the AVC. The indigenous climate change adaptation strategies were availability, low cost, and easily accessible; hence they were popularly adopted by male and female AVC actors. The adopted indigenous adaptation strategies challenged the social relations, influenced reordering of social and gender relations, participation, and power relation among the male and female actors along the AVC.

Chapter 1 situates Palestine in the context of British colonialism and technology transfer. The character of the electric power system that was built in Mandate Palestine was influenced by a prevailing logic of colonial development. Large technological systems were designed to facilitate the movement of people and the production, circulation, and consumption of things, information, and capital on the world market, on the assumption that global free trade would yield economic growth and civilizational advancement the world over. In this way, British policy in Palestine reflected an empire-wide agenda of economic development.

Hybrid energy systems (HESs) are an excellent solution for electrification of remote rural areas where the grid extension is difficult or not economical. Usually, HES generally integrate one or several renewable energy sources such as solar, wind, hydropower, and geothermal with fossil fuel powered diesel/petrol generator to provide electric power where the electricity is either fed directly into the grid or to batteries for energy storage. This chapter presents a review on the solution approaches for determining the HES systems based on various objective functions (e.g. economic, social, technical, environmental and health impact). In order to take account of environmental and health impacts from energy systems, several energy optimization model was developed for minimizing pollution and maximizing the production of renewable energy.

Full textAbstract:
The economic contribution that OTEC will make to the solution of the nation’s energy problems depends on its perceived merits relative to existing and alternative sources of energy and fuels. The previous chapters have shown that OTEC technology is ready for large-scale demonstrations that will provide a firm basis for commercial development. OTEC can have a large impact on U.S. energy needs by supplying liquid fuels for direct use in transportation, or for electric power production via fuel cells. Its commercial development will depend finally on political and other factors that cannot be assessed quantitatively. The national security and environmental impacts of continuing dependence on oil should receive major emphasis in decisions to implement new processes for fuel production. In this chapter we review the estimated sales prices of fuels and electric power from existing and proposed sources and compare them with OTEC prices. Actual manufacturing costs are generally unavailable and are highly dependent on the financing methods and resources of the individual producer. However, an objective comparison of the sales prices of fuels produced by proposed processes can be made by using the Mossman financial analysis method to estimate the sales price of fuel or electric power that must be charged for profitable operation. This requires only information on the plant investment, input fuel costs, and operation and maintenance costs. The sensitivity of the product costs to changes in the estimates in plant investment can then be displayed in a suitable graph. With this procedure the alternatives can be equitably compared from a uniform point of view. This includes costs of related facilities as well as the plant investment. See the discussion in Section 7.3. These costs vary with time in an unpredictable manner. Past forecasts have been in error by large factors. These costs are a small part of the total, typically a few percent of plant investment for capital-intensive projects. Environmental impact costs have usually been ignored. These items are a few percent of plant investment. State and local property taxes will be zero for sea-based OTEC systems.

Full textAbstract:
The agricultural operations in India are suffering from a serious problem of shortage of electrical power on one side and economic and effective disposal of agriwaste stuff on the other. India being agriculture based country, 70% of its main income (share in GDP) comes from agriculture sector. Any enhancement of income from this sector is based upon adequate supply of basic inputs in this sector. Regular and adequate power supply is one such input. But, the position of power supply in our country defies both these characteristics. With a major portion of power produced being sent to the industrial and urban consumers, there is a perennial shortage of power in the agriculture sector. Consequently, there is an emergent need to produce more power in order to fulfil the needs of this sector effectively. One way of accomplishing this is setting up captive, preferably rural based, small power generation plants. In these power plants, instead of water-head, diesel oil or coal, we can use agri-residue to produce electricity. One such power plant (1–2 MW capacity) can satisfy the power need of 25 to 40 nearby villages. The agriwaste like rice straw, sugarcane-trash, coir-pith, peanut shells, wheat stalks & straw, cottonseed, stalks and husk, soyabean stalks, maize stalks & cobs, sorghum. Bagasse, wallnut shells, sunflower seeds, shells, hulls and kernels and coconut husk, wastewood and saw dust can be fruitfully utilized in power generation. This stuff is otherwise a waste and liability and consumes a lot of effort on its disposal; in addition to being a fire and health hazard. Agriwaste stuff which at present is available in abundance and prospects of its utilization in producing energy are enormous. This material can be procured at reasonably low rates from the farmers who will thus be benefited economically, apart from being relieved of the responsibility of its disposal. Agri-residue has traditionally been a major source of heat energy in rural areas in India. It is a valuable fuel even in the sub-urban areas. Inspite of rapid increase in the supply of, access lo and use of fossil fuels, agri-residue is likely to continue to play an important role, in the foreseeable future. Therefore, developing and promoting techno-economically-viable technologies to utilize agri-residue efficiently should be a persuit of high priority. Though there is no authentic data available with regard to the exact quantity of agricultural and agro-industrial residues, its rough estimate has been put at about 350 mt per annum. It is also estimated that the total cattle refuse generated is nearly 250 mt per year. Further, nearly 20% of the total land is under forest cover, which produces approximately 50 mt of fuel wood and with associated forest waste of about 5 mt.(1). Taking into account the utilization of even a portion (say 30%) of this agri-residue & agro-industrial waste as well as energy plantation on one million hectare (mha) of wastelands for power generation through bioenergy technologies, a potential of some 18000 MW of power has been estimated. From the foregoing, it is clear that there is an enormous untapped potential for energy generation from agri-residue. What is required is an immediate and urgent intensification of dedicated efforts in this field, with a view to bringing down the unit energy cost and improving efficiency and reliability of agri-waste production, conversion and utilisation, leading to subsequent saving of fossil fuels for other pressing applications. The new initiatives in national energy policy are most urgently needed to accelerate the social and economic development of the rural areas. It demands a substantial increase in production and consumption of energy for productive purposes. Such initiatives are vital for promoting the goals of sustainability. cleaner production and reduction of long-term risks of environmental pollution and consequent adverse climatic changes in future. A much needed significant social, economic and industrial development has yet to take place in large parts of rural India; be it North, West, East or South. It can be well appreciated that a conscious management of agri-residue, which is otherwise a serious liability of the farmer, through its economic conversion into electric power can offer a reasonably viable solution to our developmental needs. This vision will have to be converted into a reality within a decade or so through dedicated and planned R&D work in this area. There is a shimmering promise that the whole process of harvesting, collection, transport and economic processing and utilisation of agri-waste can be made technically and economically more viable in future. Thus, the foregoing paras amply highlight the value of agri-residue as a prospective source of electric power, particularly for supplementing the main grid during the lean supply periods or peak load hours and also for serving the remote areas in the form of stand-alone units giving a boost to decentralised power supply. This approach and option seems to be positive in view of its potential contribution to our economic and social development. No doubt, this initiative needs to be backed and perused rigorously for removing regional imbalances as well as strengthening National economy. This paper reviews the current situation with regards to generation of agriwaste and its prospects of economic conversion into electrical power, technologies presently available for this purpose, and the problems faced in such efforts. It emphasizes the need for an integrated approach to devise ways and means for generating electrical power from agriwaste; keeping in mind the requirements of cleaner production and environmental protection so that the initiative leads to a total solution.

There exists a widespread interest in the application of gas turbine Power Augmentation Technologies (PATs) in both electric power generation and mechanical drive markets. This interest is attributable to liberalization in the power generation sector, increased electric rates during peak demand period and need for a proper selection of the gas turbine in a given application. In the Part II of this study, an analytical evaluation of the ambient temperature effect on gas turbines performance is presented. Further, the achievable power boost due to the installation of the most adopted PAT strategies is deeply investigated. Considering a whole year of operation for a large number of worldwide locations, also the behavior change — due to the use of the PATs — on both the energy production and the economic aspect will be analyzed and discussed.

A deterministic quantitative model has been developed for use to compare the technical, economical and environment feature of various electric power generating plants. The model, which is based on matrix operations, is used in evaluating the various aspects of energy sources available for the electricity generation systems in a developing country. Several energy sources are chosen which could be considered for production of electricity to meet current and future electricity demands. A complete set of energy sources will include fossil fuel fired power plants, nuclear power plants, and natural-renewable energy power plants. A customized computer code is developed to evaluate the overall function for each system from the performance corresponding to the selected energy attributes includes five area of concerns; energy economy, energy security, environmental protection, socio-economic development and technological aspects for the electric power generations. The model developed in this study is applied to the Indonesian’s electric power sector development. Most of the data required for the model application are obtained from various sources related to power industry in Indonesia, such as the Electricity Generating Authority of Indonesia (Perusahaan Listrik Negara, PLN), Government of Indonesia, World Bank, Asian Development Bank, United Nations, and other sources, both in published and public domains. The optimization technique is kept flexible so that it can accommodate other attributes that will be found to be important according to the decision maker’s preference. By so doing, the model virtually can be used to attack any decision problem with various different attributes to reach an optimal decision concerning the selection of energy sources for electricity generation. The result of this study will be a rank of energy sources for Indonesia power generation systems based on the composite distance of each alternative to the designated optimal source of energy.

Full textAbstract:
Abstract Polygeneration improves energy efficiency and reduces both energy consumption and pollutant emissions compared to conventional generation technologies. A polygeneration system is a variation of a cogeneration system, in which more than two outputs, i.e., heat, power, cooling, water, energy or fuels, are accounted for. In particular, polygeneration systems integrating solar energy and water desalination represent promising technologies for energy production and water supply. They are therefore interesting options for coastal regions with a high solar potential, such as those located in southern Peru and northern Chile. Notice that most of the Peruvian and Chilean mining industry operations intensive in electricity and water consumption are located in these particular regions. Accordingly, this work focus on the design and integration of a polygeneration system producing industrial heating, cooling, electrical power and water for an industrial plant. In particular, the design procedure followed in this work involves integer linear programming modeling (MILP). The technical and economic feasibility of integrating renewable energy technologies, thermal energy storage, power and thermal exchange, absorption chillers, cogeneration heat engines and desalination technologies is particularly assessed. The polygeneration system integration carried out seeks to minimize the system total annual cost subject to CO2 emissions restrictions. Particular economic aspects accounted for include investment, maintenance and operating costs.

Full textAbstract:
Renewable power production is both variable and difficult to forecast accurately. These traits can make its integration into an electric grid problematic. But because its “fuel” is free, it makes economic sense to utilize renewable energy whenever it is available. When a power grid is unable to accommodate low marginal cost renewable energy due to a generator fleet that lacks sufficient flexibility, the energy is usually wasted and dispatchable fossil fuel generators are utilized instead. However, if a pumped hydroelectric storage (PHS, see the glossary for definitions of select terms) facility is used to time shift the renewable power production, the energy is transformed into a dispatchable resource. Because of this dispatchability, the power can be sold as “firm” generation which typically gets a higher price on the wholesale electricity market. This paper will address the financial aspects of using PHS to firm and time shift the inherently variable wind and solar power generation in the Mid-Atlantic States. The benefits that a PHS facility can offer to renewable power generators are many, but the biggest drawback to doing so is the high capital cost of PHS. In order to study the revenue streams of both PHS facilities and renewable power generators a computer model with one minute granularity was constructed. Electricity demand, power prices and wind power production were obtained from PJM’s website for the year 2010. The NREL program PVWatts v.1 was used to generate the simulated solar power production which was combined with the PJM data and used as input to the model. Currently, various PHS configurations are being tested in order to determine their effects on the profits of the PHS facility and the profits of renewable generators. Preliminary results show that the relationship between PHS owners and renewable power generators could be beneficial for both parties. The extents of the financial benefits are largely determined by the dynamics of the applicable wholesale electricity market, the accuracy of the power production forecast for renewable generators, the power capacity, the energy capacity and the round trip efficiency of the PHS facility.

Full textAbstract:
Economic reasons, leading to the use of coal and the environmental concerns, call for clean technologies for the electric power production. Accordingly the adoption of Integrated Gasification Combined Cycle (IGCC) plants with Carbon Capture and Storage (CCS) has been pushed. Such a technology is promising but it still shows some critical aspects. Some of them are related to stable and controllable operations of commercially available Gas Turbines (GTs) designed to be fed with Natural Gas (NG) once the original fuel is replaced by the hydrogen-rich syngas produced in an IGCC-CCS plant. The thermo-physical properties of the H2-rich syngas require investigations and modifications of the combustor and of the turbomachines to meet stable and safe GT behaviour. Such properties strongly affect the matching between GT compressor and expander. To run the GT with the syngas, various options can be taken into account. Some of them do not require GT flow function modifications, while other options involve compressor and expander structural changes. In the present paper some compressor modifications that can be adopted to maintain an F Class GT performance and stability are explored. Such modifications have been analysed by means of a high fidelity quasi-one-dimensional model based on an Elemental Component Finite Volume approach for the GT sizing and analysis. Results have been compared and deeply discussed.

Full textAbstract:
DOW (Deep Ocean Water: The sea water below 200m depth) which has three major characteristics, Low Temperature, Rich Nutrient and Very Clean, is expected as a future renewable resources in the ocean. Toward the era of environment and low carbon, utilizing the ocean renewable resource is absolutely important because the land base resources are now peaking out. In order to making use of DOW effectively and economically, multi-purpose utilizing of DOW is recommended because it has many aspects of characteristics and advantages. First, Electric Power generation by OTEC (Ocean Thermal Energy Conversion) is carried out using the difference of water temperature between the cold DOW (5°C) and the warm surface water (25°C). Second, a fresh water generation by a desalination of the sea water is carried out using residual difference of temperature after OTEC operation. Third, the DOW after discharging cold temperature in the heat exchanger of fresh water generator is scattered into a photosynthetic surface layer in the sea and its nutrient enhances primary production of the sea and eventually make a rich fishing ground. Forth, Lithium and some other rare metal are absorbed from DOW by putting special filters in the continuous large quantity flow of DOW. In this paper, the multi-purpose DOW platform which generates the electric power, the fresh water, the fishes and the Lithium from only DOW and surface water is proposed as a supplier of infra-structure for an isolated island. Technical and economical feasibility study is carried out and the result is that the enough sized multi-purpose DOW platform is very feasible for the forthcoming environment era.

Full textAbstract:
Wind power is a source of clean, nonpolluting electricity, which is quite competitive, if installed at favorable wind sites, with fossil fuel and nuclear power generation. Wind power is an intermittent electricity generator; which does not provide electric power on an “as needed” basis. The major challenge in wind energy assessment is how accurately the wind energy can be predicted and the capital investment cost is estimated. Therefore, wind energy is subject to some uncertainties, which must be accounted for to provide meaningful and reliable estimates of performance and economic figures-of-merit. Off-peak power from wind farms can be utilized for hydrogen production using water electrolysis. This study applies methods of risk analysis to evaluate the simultaneous effect of multiple input uncertainties, and provide an assessment of the-techno-economic viability of offshore wind farms for electrolytic hydrogen production. The capacity factor of wind turbine has a dominant effect on the wind power economy.

Full textAbstract:
The Smart Energy Design Assistance Center assessed the administrative, technical, and economic aspects of feasibility related to the procurement and installation of photovoltaic solar systems on IDOT-owned buildings and lands. To address administrative feasibility, we explored three main ways in which IDOT could procure solar projects: power purchase agreement (PPA), direct purchase, and land lease development. Of the three methods, PPA and direct purchase are most applicable for IDOT. While solar development is not free of obstacles for IDOT, it is administratively feasible, and regulatory hurdles can be adequately met given suitable planning and implementation. To evaluate IDOT assets for solar feasibility, more than 1,000 IDOT sites were screened and narrowed using spatial analytic tools. A stakeholder feedback process was used to select five case study sites that allowed for a range of solar development types, from large utility-scale projects to small rooftop systems. To evaluate financial feasibility, discussions with developers and datapoints from the literature were used to create financial models. A large solar project request by IDOT can be expected to generate considerable attention from developers and potentially attractive PPA pricing that would generate immediate cash flow savings for IDOT. Procurement partnerships with other state agencies will create opportunities for even larger projects with better pricing. However, in the near term, it may be difficult for IDOT to identify small rooftop or other small on-site solar projects that are financially feasible. This project identified two especially promising solar sites so that IDOT can evaluate other solar site development opportunities in the future. This project also developed a web-based decision-support tool so IDOT can identify potential sites and develop preliminary indications of feasibility. We recommend that IDOT begin the process of developing at least one of their large sites to support solar electric power generation.
