This is a discussion on the paper titled “Assessing feed-in tariffs on wind power installation and industry development in Taiwan” published by Hsu et al. In the discussed paper, there were several missing variables in the historical test of the system dynamics (SD) model, and thus the test was not integrated and valid. Additionally, the simulated results of the missing variables were used as important indexes to observe the behavior of the SD model. Therefore, it was highly likely that the solution and related policy analysis based on the simulated results were incorrect. Accordingly, the present study illustrated the structure characteristics of the SD model with respect to the fore-mentioned problems, discussed the reason for missing variables and proposed a method to assess whether or not the historical test was integrated. Finally, after a careful analysis, this study offered suggestions to perfect the historical test proposed in the discussed paper. [ABSTRACT FROM AUTHOR]

Recently China's wind power industry is challenged by many problems such as wind power integration and wind curtailment, which seriously hinders the development of onshore wind power. Since China's policy has a direct and significant influence on wind power industry, it is vital to analyze and evaluate published policies. This paper explores in detail 134 China's onshore wind power policies from 2005 to 2015 so as to provide analytical support for future formulation and implementation of wind power policy. Based on policy summary from equipment manufacturing industry, wind farms and power grid industry, this paper evaluates the policies from the perspective of overall plan, support policy and policy implementation using fitting method, game theory and empirical analysis. The results indicate that China's wind policy is gradually becoming perfected, for example, there are more reasonable objectives and improved support policies. However, many problems remain to be solved, like unreasonable planning, imperfect support policies, immature trading systems and uncoordinated actions among interest related parties. Furthermore, combined with international experiences, suggestions on improving China's wind power policy are proposed from seven aspects. [ABSTRACT FROM AUTHOR]

The rapid growth of China׳s installed wind power capacity in recent years is closely related to the wind energy policies issued by the Chinese government. Using content analysis and quantitative analysis methods, this paper studies the historical evolution of Chinese wind energy policies. Based on 72 wind energy policies issued in the past two decades (1995–2014), this paper analyzes the issuing organization, form, number and stringency of wind energy policies and compares different policy instruments in two periods. The results show that the number and stringency of wind energy policies fluctuated greatly from 1995 to 2014 and that more than twenty organizations had independently or jointly issued the policies. The main organization issuing wind energy policies, however, is the department that controls key economic and administrative resources and not the one that is in charge of wind energy. Of the 72 policies issued, twenty-three took the form of notices, and eleven were measures. As to the policy instrument, environmental policies are most widely applied by the Chinese government, and “regulation control” and “goal-planning” instruments are the ones most frequently adopted. Furthermore, the application of supply- and demand-type policies is inadequate, and few effective instruments have been adopted. [ABSTRACT FROM AUTHOR]

This paper is an enquiry into the role of State policies in influencing wind installed capacity. The paper studies the impact of policies on deployment of wind potential across the States of India over two decades. Aggregate indices are computed for each of the seven wind resourceful States of India indicating attractiveness for installed capacity of wind energy. For computing the indices, four policies, Feed-in-Tariff, Renewable Purchase Obligation, Banking facility, and Wheeling charges are considered. Panel data techniques are then employed to investigate the impact of the policy differences on wind potential deployment over the 19 year period (1993–2012) after controlling for three State-specific factors. The controlling factors include per-capita income of the State, power deficit, and ratio of installed capacity of wind to geographic potential indicating unmet capacity. The results show that that policy index positively impacts wind deployment whether control variables are included or not. Moreover, the control factors like the per-capita income of the State and unmet capacity have positive influence over the investment in wind energy. [ABSTRACT FROM AUTHOR]

Abstract: This paper aims to advance research into the effectiveness of policies for encouraging technological transition in the energy sector (in general) and wind power (in particular). It contends that the ineffectiveness of wind power development policy in most nations stems from a linear approach to policy design that is unsuited to complex adaptive markets. The paper argues that in complex adaptive markets, policies are required that foster competition on a level playing field. Insights are extracted from complexity theory to advance four principles for effective wind power policy in such markets. These principles include establishing policy initiatives to: encourage technological diversity, establish clear and progressive short to medium-term targets, enhance environmental monitoring systems and establish a malleable policy regime that directly resolves emergent challenges while simultaneously sustaining market momentum to ensure long-term targets are met. In order to demonstrate the applied relevance of these principles, the paper applies these concepts to a historical analysis of Denmark''s wind power development policies. [Copyright &y& Elsevier]

Abstract: Since 2005, there has been dramatic progress in China''s wind power industry. The annual growth rate of newly constructed capacity reached a miracle of 105% and the total installed capacity has increased from 1.27GW in 2005 to 44.73GW in 2010, which has exceeded the target of China''s energy long-term planning for 2020. During the 11th Five-Year-Plan (FYP), the Chinese government has issued a series of polices to promote and regulate the development of wind power industry, which is the underlying force driving its rapid development. This paper is a systematical review on the current status and policies of wind power industry in China. Firstly the current status including achievements and shortcomings is presented, and then the relevant polices and regulations released during the period of 11th FYP are reviewed. Meanwhile, the main approaches of the policies and regulations in promoting the development of wind power industry are discussed and the issues of the current policies are analyzed. Finally, the paper concludes on the perspectives of wind power policies in China. [Copyright &y& Elsevier]

South Korea's new energy transition policy was declared in 2017 as citizen demand grew for solutions to safety problems caused by successive earthquakes affecting areas with many nuclear power plants in 2016 and 2017 as well as health problems caused by coal-fired power plants contributing to high condensable particulate matter in spring. This policy focuses on both a reduction in nuclear and coal-fired power plants and further development of eco-friendly and sustainable power generation and supply. The South Korean government is thus planning a large-scale transition toward improved energy efficiency as well as safe and clean energy sources. Its announced goal is to supply a 20% share of renewable energy in the national energy mix, including 37 GW of photovoltaic power, 3 GW of onshore wind power, and 13 GW of offshore wind power by 2030; the latter is expected to play a strategic role in the Renewable Energy 2030 plan. As South Korea's geographic conditions enable large-scale offshore wind farm projects that are relatively free from complaints and visual effects caused by transportation, installation, noise, vibration, and damage to natural environments, it is highly likely that wind power will become one of the nation's major renewable electricity sources. This paper discusses the potential for developing offshore wind farm projects in South Korea with particular focus on analyzing offshore resources and reviewing government policies and support programs that could limit or otherwise challenge the deployment of such projects, with further considerations of policy choices that could improve the deployment of offshore wind power. As the greatest hindrances to offshore wind power development are frequently-changed government policies and support programs, the adoption of consistent, stable, and efficient guidelines and supports would be most beneficial for meeting South Korea's goals of increased offshore wind energy supplies. • A broader approach to analyze the S. Korea's offshore wind energy policy, regulatory frameworks, supports and supply chain. • An overview of the offshore wind energy potentials and the current projects in South Korea. • Identifies the key barriers faced by the offshore wind energy industry. • Emphasizes the importance of the government's policy development to achieve the offshore wind power deployment target.

Offshore wind energy generation has experienced an important growth in the last five years, reaching currently an installed capacity of almost 8000 MW. The most important references in this type of technology are Denmark, Holland, Sweden, Germany and United Kingdom. In Spain, previsions for technology, have been set at around 750 MW of installed power during the period 2011–2020. However, Spanish coastal features, social opposition to installations near the coast and lack of a stable regulatory environment guaranteeing the investments are factors which are restraining the development of this technology. This paper presents a brief review of the state of the art of offshore wind technology and it describes the most frequently used types of turbines, transmission systems and support structures in Europe. It also presents the current situation and the expected growth of offshore wind power facilities, introducing the characteristics of the operational – and under construction – windfarms. Finally, it analyses particular problems and solutions for its development in Spain which can be extrapolated to countries with similar circumstances. [ABSTRACT FROM AUTHOR]

Acceptance plays an important role in the successful adoption of wind energy technology. This article identifies factors influencing the acceptance of wind energy and selects those factors which have the highest relevance for wind energy acceptance in Bavaria. We decided to analyze the Federal State of Bavaria in Germany as its current policy governance decelerates the building-up of wind turbines in this federal state. Using a qualitative approach, the results indicate that the perception of political processes, such as the recent enacting of the 10-H regulation in Bavaria, influences the acceptance towards wind energy, as trust and transparency in political processes are essential. In addition, the paper reveals the importance of the distributive justice, focusing in particular on the subitem envy, which can be considered on a neighboring or regional level. Additionally it reveals additional factors which are relevant for wind energy acceptance in the specific case of the analyzed federal state. [ABSTRACT FROM AUTHOR]

This paper deals with the simultaneous scheduling of electrical vehicles and responsive loads to reduce operation cost and emission in presence of wind and PV powers in microgrid. In the proposed method, the electrical vehicles are used for peak shaving and load curve modification while the responsive loads are employed to supply the reserves needed to compensate the intrinsic uncertainties of wind and PV powers. Furthermore, a developed two-stage model is proposed to determine the expected operation cost of microgrid (energy and reserve). In the first stage, the generation and reserve power costs are minimized while in the second stage, the costs associated with unit scheduling changes resulting from wind and PV power variations are minimized. The proposed model is implemented in a microgrid with various distributed generations. The simulation results have shown that the incorporation of electrical vehicles and responsive loads leads to decrease the system operation costs and emissions while the uncertainties related to wind and PV are compensated.

This study focuses on the problem of generation expansion planning and the integration of an increasing share of renewable energy sources (RES) technologies in the power grid. A survey of papers addressing the use of optimization models for electricity generation planning is presented. From this, an electricity planning model able to integrate thermal and RES power plants was proposed. An analysis of different electricity scenarios for a mixed hydro–thermal–wind power system is presented using the proposed mixed integer optimization model. The results show the importance of these tools to support the strategic energy policy decision making under different regulatory or political scenarios. The expected impacts in terms of costs and CO 2 emissions are evaluated for a 10 year planning period, and a set of optimal scenarios is analyzed. The use of the model to obtain and characterize close to optimal scenarios is shown to be strategically useful. In particular the impact of different wind power scenarios is addressed, demonstrating the relevance of assessing other possible strategies that, despite not being original Pareto solutions, may be worth considering by the decision makers.

In recent years, the Malaysian government has attempted to develop renewable energy (RE) through newly introduced regulatory supports after 30 years of failure to achieve a greater than one percent non-hydroelectric RE share in the total power mix. The government is currently assessing the onshore wind energy potential in Malaysia to determine the possibility of including wind energy in its FiT scheme. However, wind energy development in this low-energy location is not as straightforward as it would seem. Many previous wind studies in Malaysia have relied on poor data and simplistic or inadequate methodologies, resulting in grossly inaccurate estimates of wind potential. Moreover, two wind turbine generator demonstration projects executed by the government have failed. However, above all, the greatest factor impairing the progress of RE development in Malaysia is the weak and uncertain political support of these efforts. This lack of robust support is particularly true where fossil fuels are still heavily subsidised amid the subsidy reform in 2013. A review of global wind energy development shows that successful projects depend heavily on a sound and robust regulatory framework supported by strong and consistent political will. This dependence is not observed in Malaysia, where the government continues to subsidise private independent fossil fuel power producers but levies taxes on electricity consumers to fund RE development. These levies do not effectively support RE development, given the magnitude of the RE fund compared to fossil fuel subsidies. In the absence of strong and sincere political will, the progress of RE development in Malaysia has been notably slow. As a result, the prospect of wind energy development in Malaysia currently remains vague. This paper discusses the above issues in detail and recommends selected regulatory mechanisms based on the global experience of supporting RE development in Malaysia. [ABSTRACT FROM AUTHOR]

With the rapid development of human society, the demand for energy has accordingly increased, and along with this increasingly serious energy and environmental crises have developed. Many countries have been focusing on new energy resources to combat these crises, and offshore wind energy resources are especially attractive; they are safe, non-polluting, renewable, and widely distributed with large reserves, which has made them become the focus of developed countries. However, the distribution of wind energy has strong regional and seasonal differences, which determines the success and efficiency of wind energy developments. Therefore, there is a clear need for “resource evaluation and planning in advance” in the wind energy development. Previous research has made a great contribution to the evaluation of offshore wind energy resources, mostly through analysis of the climatic characteristics of wind energy. In the actual development process of wind energy resources, these analyses of the climatic characteristics of wind energy provide a reference for site selection. However, after constructing wind farms, to aid their operation, there needs to be a more comprehensive understanding of other factors, such as the short-term forecasting and medium- to long-term predictions of wind energy. This paper reviews the research progress of the wind energy resource evaluations, and then considers where future research needs to focus, for the evaluation of wind energy resources. This mainly includes further analyses of the climatic characteristics of wind energy, short-term forecasting, medium- to long-term predictions, early disaster warning systems, the establishment of a wind energy development index (WEDI) and an integrated application system, in hope of providing a reference for offshore wind power generation, seawater desalination and other wind energy resource developments, and accelerating the industrialization and utilization of offshore wind energy. Doing this will alleviate the energy and environmental crises, and promote the sustainable development of human society. [ABSTRACT FROM AUTHOR]

Renewable energy can play a strategic role in India in meeting the country’s growing energy demands, as well as combating climate change. Policymakers have recognized this potential and over the last decade have intensified their efforts towards creating a conducive regulatory and policy framework. Policy instruments such as renewable obligations, feed-in-tariffs and generation based incentives have specially aided the transformation towards large scale generation, enabling higher efficiency and lower costs of generation. However, financing has emerged as a significant barrier for sustaining the momentum gained in recent years. Given this background this paper provides an overview on the evolution of large scale generation and the consequent changes in financing requirements. It further reviews the emerging trends and barriers in the financing landscape and analyses the impact of policy performance in this context. Finally, it considers the design of a national renewable finance framework complete with targeted finance push instruments that can complement existing demand pull policies in facilitating investment.

Integrating variable and non-dispatchable renewable power generation into existing power systems will have consequences for their operation and future expansion. These impacts will depend on two factors: (1) the variability of the total renewable power generation on different time scales and (2) the possibilities of accurately forecasting these fluctuations. In this paper, previous research on variability assessment and forecasting of solar, wind, wave and tidal energy resources is reviewed. The aim is to summarize the state of knowledge in each area and to compare the approaches used for the respective resources. For temporal variability, methods and models used for assessing the variability are surveyed, as well as what is known about the variability at individual sites and for larger aggregates of sites. For forecasting, an overview of forecasting methods for the different resources is made, and selected forecasting methods are compared over different time horizons. An important finding is that it is hard to draw strong conclusions from the existing studies due to differences in approaches and presentation of results. There is a need for further, more coherent studies that analyze the variability for the different resources in comparable ways, using data with the same resolution, and for studies that evaluate the smoothing effect and complementarity of combinations of several renewable energy resources. For forecasting, future research should suggest ways to evaluate forecasts from different renewable energy sources in easily comparable ways, using data from the same locations or regions, with the same temporal and spatial resolution, and with comparable metrics for the forecasting errors.

In recent time, the concern for grid integration of wind power has been a subject of discussion in the academic community. At present, the penetration level is still moderate for most grids to accommodate. As the penetration level increases, wind power may cause additional problems to the grid due to its intermittent nature. One of the intending solutions to this problem is the adoption of energy storage. This paper examines the state of the art energy storage technology options that are capable of mitigating wind power intermittency on the grid and their challenges. It also highlighted the existing policies that aided the development of wind power and discusses the limitations of its integration into the grid. It was found that, the ability of storage technology to be effectively utilised in mitigating the wind power intermittency depends on the ramp rate of the technology, response delay time, duration of storage, maturity of technology, installation cost, efficiency of the technology, its environmental impact and the suitability of the site topology. Therefore, no single storage technology is capable of providing total solution at mitigating the effect of wind power intermittency on the grid. The effectiveness of the storage technology lies in the hybridization of the storage technologies depending on the level of cost and technical requirements. [ABSTRACT FROM AUTHOR]

A significant number of Life Cycle Assessment (LCA) analyses of renewable energy technologies is available in the literature, even though there is a lack of consistent conclusions about the life cycle impacts of the different technologies. The reported results vary consistently, according to the size and the technology of the considered plant, thus limiting the utility of LCA to inform policy makers and constituting a barrier to the deployment of a full awareness on sustainable energies. This variability in LCA results, in fact, can generate confusion regarding the actual environmental consequences of implementing renewable technologies. The article reviews approximately 50 papers, related to more than 100 different case studies regarding solar energy (Concentrated Solar Power, Photovoltaic), wind power, hydropower, and geothermal power. A methodology for the harmonization of the results is presented. The detailed data collection and the results normalization and harmonization allowed a more reliable comparison of the various renewable technologies. For most of the considered environmental indicators, wind power technologies turn out to be the low end while geothermal and PV technologies the high end of the impact range where all the other technologies are positioned.

Abstract: Wind power is one of the world׳s major renewable energy sources, and its utilization provides an important contribution in helping solve the energy problems of many countries. After nearly 40 years of development, China׳s wind power industry now not only manufactures its own massive six MW turbines but also has the largest capacity in the world with a national output of 50millionMWh in 2010 and set to rise by eight times of that amount by 2020. This paper investigates this development route by analyzing relevant academic literature, statistics, laws and regulations, policies and research and industry reports. The main drivers of the development in the industry are identified as technologies, turbines, wind farm construction, pricing mechanism and government support systems, each of which is also divided into different stages with distinctive features. A systematic review of these aspects provides academics and practitioners with a better understanding of the history of the wind power industry in China and reasons for its rapid development with a view to enhancing progress in wind power development both in China and the world generally.

Abstract: In addition to providing a review of electricity generation developments in China, this paper features the development of a framework for understanding the socio-political economy influencing electricity market development. It documents and presents a critical evaluation of the social, technological, economic and political forces which influence electricity generation policy in China. The analysis provides insight into why China's electricity generation shopping basket is being filled with both coal and CO2-reduced electricity generation technologies. It concludes that installed capacity of hydro power, wind power, nuclear power and solar PV power will outpace government projections due to inter alia a proclivity on the part of the Chinese government to set conservative (and achievable) targets, waning apathy toward pollution associated with coal-fired power, progressive improvements in grid connection and resilience, increased economic viability of these alternative energy sources and government support for these industries as strategic commercial sectors.

Abstract: Wind power installation in China has increased rapidly since 2004. However, wind power usage remains relatively low resulting in a lot of idle capacity beginning in 2007. In this paper, we determine the main framework of China's current wind power policies and illustrate how these policies led to the rapid installation expansion accompanied by large idle capacity. Building on this, we explore how to alleviate the high installation low wind power usage conflict in China. We establish optimal models to (i) analyze wind power and power grid company behavior; (ii) demonstrate the impact of China's current policies on power and grid companies; and (iii) clarify the causes and mechanisms resulting in high growth and low wind power capacity usage. Our analysis shows that the incentive incompatibility of current policies, which enticed power companies to pursue installation expansion regardless of quality while inhibiting grid companies from improving connectivity, transmission and scheduling technology, is the primary cause for such large-scale idle capacity. The results of our study suggest that the fundamental way to scale up wind power utilization is to enhance policy incentive compatibility, which mainly includes (i) distributing revenues and diversifying risk fairly between power and grid companies; and (ii) motivating power companies to address demand fluctuation actively.

Abstract: Global exploitation of renewable energy technologies is increasing rapidly due to the concern in global warming and dwindling supplies of fossil fuels. Most of the countries in the world are blessed with two or more renewable energy sources (RES) and hence have formulated policies to boost the utilization of RES for their electricity production. An assessment of renewable electricity scenario is essential for research and development related works in the field of renewable energy technologies in order to further develop the renewable energy industry. Recent developments in installation capacities, costs and reductions in electricity costs of major RES based electricity generation methods are discussed in this paper. It also includes the past growth and future expectations of renewable electricity production. The analysis shows that if the current developments in renewable industry continue, then a major share of global electricity production in the future could be supplied by renewable energy technologies. The analysis further shows that a significant amount of fuel cost and pollutants emission can be reduced by the increased use of RES based electrical power production technologies.

Abstract: Over the centuries, energy has been supplied by wood, coal, oil and natural gas, as well as by uranium. All these energy sources are limited and create pollution problems. This has led countries to focus on a sustainable and cleaner energy sources. Wind energy is rapidly emerging as one of the most cost-effective forms of renewable energy with very significant increases in annual installed capacity around the world. In this paper, authors have tried to review the current state of wind power utilization in Ethiopia. First, a brief overview is given on the Ethiopian electric power sector in order to gain insight into the main energy sources of the country and installed electric power capacities. Wind energy potential and current energy policy in Ethiopia were discussed respectively in the subsequent sections. Finally, short reviews of the ongoing and planned wind energy together with other renewable energy projects are given. Ethiopia, a country that relies on hydroelectric plants for the bulk of its power, is now developing significant wind energy capacities. Lack of reliable wind data covering the entire country has been one of the reasons for limited application of wind energy in Ethiopia, but recently studies have shown that Ethiopia has substantial potential to generate electricity from wind, geothermal and hydropower. Considering the substantial wind resource in the country, the government has committed itself to generate power from wind plants by constructing eight wind farms with total capacities of 1116MW together with a number of hydropower plants over the five year Growth and Transformation Plan (GTP) period from 2011 to 2015. This development of wind power is a part of the current energy sector policy of the country that aims at a five-fold increase in renewable energy production by the end of 2015.

Abstract: It is highly significant for China to improve its development of wind power. In order to promote the sustainable development, a more comprehensive evaluation of factors affecting the effectiveness of investment in the industry wind power is required to be conducted to formulate a relatively stable policy supporting mechanism for the development of wind power. Based on the green accounting framework, this paper evaluates a typical wind power project from economic, environment and energy alternative respects comprehensively. We simulate the main factors influencing cost and benefit of the wind power investment with the Monte Carlo method. Finally, we discuss how to promote wind power with respect to the concern of government, investors and environmentalists. [Copyright &y& Elsevier]

Abstract: Over the last decade there has been a rapid global increase in wind power stimulated by energy and climate policies. However, as wind power is inherently variable and stochastic over a range of time scales, additional system balancing is required to ensure system reliability and stability. This paper reviews the technical, policy and market challenges to achieving ambitious wind power penetration targets in Ireland’s All-Island Grid and examines a number of measures proposed to address these challenges. Current government policy in Ireland is to address these challenges with additional grid reinforcement, interconnection and open-cycle gas plant. More recently smart grid combined with demand side management and electric vehicles have also been presented as options to mitigate the variability of wind power. In addition, the transmission system operators have developed wind farm specific grid codes requiring improved turbine controls and wind power forecasting techniques. [Copyright &y& Elsevier]

Abstract: With regard to energy conservation and the reduction of emissions, China is dedicated to facilitating the development of renewable energy in order to fulfil its international responsibility. In recent years, the installed wind power capacity in China has increased rapidly due to its large scale and centralization. The high penetration of wind power has brought about a series of problems such as the wind energy utilization and curtailment, auxiliary services and the pricing mechanism. The resolution of these problems needs policies which will provide more support than the current technologies and standards for wind power. This paper takes the evaluation of capability of accepting large-scale wind power in China as its object of study. According to the analysis of such risk factors as the influence of the grid on wind power integration, wind power itself, the market and policy, an evaluation model of the ability of accepting large-scale wind power is established based on risk theory. Then, the estimation of the ability to accept wind power in Gansu Province is used to testify to the effectiveness of this model. Finally, a series of reasonable policies for wind power are proposed.

Abstract: The growth of the renewable energy sector in the world in the first decade of the twenty-first century was rapid. Wind energy sector was one of the fastest growing renewable energy technologies. In this paper, authors have tried to review the current state of wind power utilization in Serbia as one of the most penetrating RES technologies in the world. The brief overview of electric power sector in Serbia was given in order to describe the environment for emerging wind energy sector development. Sufficient wind energy resources were identified in several regions of the country. Current energy policy in Serbia was reviewed in terms of the regulations that have to be followed in order to meet the requirements for RES power plants, i.e. wind power plant construction. In subsequent section short reviews of wind energy projects which are in their initial phases are provided. The wind energy sector in Serbia is emerging despite the difficulties faced by the investors, regulatory bodies and other shareholders, in the course of the past several years. There is an urgent need of a broader transfer of specific knowledge and technologies related to wind farms and wind turbines in order to speed up the current wind energy sector development.

Abstract: Wind power has a significant contribution to make in efforts to abate CO2 emissions from global energy systems. Currently, wind power generation costs are approaching parity with costs attributed to conventional, carbon-based sources of energy but the economic advantage still rests decidedly with conventional sources. Therefore, there is an imperative to ensure that wind power projects are developed in the most economically optimal fashion. For wind power project developers, shaving a few tenths of a cent off of the kilowatts per hour cost of wind power can mean the difference between a commercially viable project and a non-starter. For civic authorities who are responsible for managing municipally supported wind power projects, optimizing the economics of such projects can attenuate stakeholder opposition. This paper attempts to contribute to a better understanding of how to economically optimise wind power projects by conflating research from the fields of energy economics, wind power engineering, aerodynamics, geography and climate science to identify critical factors that influence the economic optimization of wind power projects.

Abstract: A widely accepted premise regarding wind power development policy is that implementation of economic policy instruments, which are designed to close the cost gap between wind power and entrenched fossil fuel power generation technologies, will significantly catalyze enhanced levels of wind power development activity. This paper contests this premise by arguing that non-economic barriers to wind power development have the capacity to significantly inhibit wind power development in industrialized nations despite the implementation of economic policy instruments. Forces which deter wind power development in four economically advanced economies that exhibit phlegmatic progress in wind power development – Australia, Canada, Japan and Taiwan – are identified and amalgamated into a STEP framework describing social, technical, economic and political forces that inhibit wind power development. The conclusions of this analysis are twofold. First, failure to mitigate these STEP forces may undermine the efficacy of any given economic policy instrument that aims to close the cost gap between wind power and entrenched generation technologies. Second, attempts to mitigate these impediments might represent a way to achieve better policy results with less government financial commitment. [Copyright &y& Elsevier]

Abstract: Indian wind energy sector has seen a CAGR of more than 27% during the period 2002–2007. However, the annual capacity additions has been declining for the past 2 years and recently, India lost one place in the Global ranking on total installed wind capacity to China. While issues like unfavourable tariff, non-uniform state policies, unavailability of evacuation infrastructure, etc. can be attributed to the slower pace of capacity addition, the issue of unavailability of on-shore wind sites with sufficiently high wind velocity is expected to take centre stage in the next 2–3 years. Wind sites with low wind velocity make the investment unattractive to developers. Given the current situation, repowering as an investment option, which has already seen favourable response in countries like Germany and Denmark, would start maturing in India. This paper analyzes the present situation of the wind energy in India, evaluates the different wind energy market segments including repowering market, provides financial highlights of the repowering concept and ends with concluding remarks on major triggers which can set this concept in motion.

Abstract: Oman relies on gas and oil resources fuels for almost all of its energy needs. Almost 99% of its power generation is based on natural gas. However, the country''s natural gas supplies are currently largely committed, and it may become a net importer soon. Therefore, there is a need to look for alternative energy resources. This paper presents a review of the assessed potential of renewable resources and practical limitations to their considerable use in the perspective of present scenarios and future projections of the national energy for Oman. Solar and wind are likely to play an important role in the future energy in Oman provided that clear policies are established by the higher authority for using renewable energy resources. Rural Areas Electric Company has initiated solar and wind pilot projects in its concession area to confirm the performance and efficiency of renewable technologies in local conditions.

Abstract: Wind power in China registered a record level of expansion recently, and has doubled its total capacity every year since 2004. Many experts believe that China will be central to the future of the global wind energy market. Consequently, the growth pattern of wind power in China may be crucial to the further development of the global wind market. This paper firstly presented an overview of wind energy potential in China and reviewed the national wind power development course in detail. Based on the installed wind capacity in China over the past 18 years and the technical potential of wind energy resources, the growth pattern was modeled in this study for the purpose of prospect analysis, in order to obtain projections concerning the development potential. The future perspectives of wind energy development in China are predicted and analyzed. This study provides a comprehensive overview of the current status of wind power in China and some insights into the prospects of China''s wind power market, which is emerging as a new superpower in the global wind industry.

Abstract: Academics, practitioners, and policy makers continue to debate the benefits and costs of alternative sources of energy. Environmental and economic concerns have yet to be fully reconciled. One view is that decisions that incorporate both society''s concern with the environment and investors’ desire for shareholder value maximization are more likely to be truly sustainable. We coin the term dual sustainability to mean the achievement of environmental and financial sustainability simultaneously. Many experts believe that wind energy can help to meet society''s needs without harming future generations. It is clean and renewable. Because the fuel is free it provides the ultimate in energy independence. Wind energy has emerged as a leading prospect, in part, because it is considered by many to be environmentally sustainable. However, a key question that remains is whether wind energy is financially sustainable without the extensive government support that has helped to create and nurture this growth industry. Using reliable, proprietary data from field research, our analysis employs a capital budgeting framework to evaluate the financial economics of investments in wind energy. We find that because of the convergence of improved technology, greater efficiency, and with the increasing cost of traditional, competing sources such as oil and natural gas, wind energy is close to becoming self-sustaining financially without the extensive federal government support that exists today. Wind energy can provide the best of both worlds. It is sustainable from an environmental perspective and it is becoming sustainable financially. In short, those companies investing in wind energy will be able to do well by doing good. Perhaps the achievement of dual sustainability is true sustainability. Our research findings and dual sustainability have several interesting and important implications for public policy towards wind energy. All imply that public policy can now be executed in a more effective and efficient manner. In the paper we outline and offer these better and cheaper public policy alternatives for consideration.

Abstract: This paper analyzes the success of wind energy in Spain from 1986 to 2007. Certain special characteristics have emerged in Spain that provide credibility to the feed-in tariff (FIT) device to promote this energy source. To explain this success, the analysis will focus on the intrinsic characteristics of FIT using the concepts of the transaction cost theory (TCE). Nevertheless, in this framework, special attention is placed on the role that specific political and institutional factors have played in providing stability to this instrument. Thanks to an early start and an on-going and generous FIT device, wind energy promotion for electricity has become a political success story in Spain. The main implication of this analysis is that this success is mainly due to the trade-off between stability and flexibility in the use of Spanish FIT. [Copyright &y& Elsevier]

As more distributed energy resources are deployed on electric grid systems across the world, it is important to identify, characterize, and quantify the value elements of different types of distributed energy resources so that policymakers, developers, and utilities can make informed energy deployment decisions. This paper focuses on the value of wind energy as a distributed energy resource (i.e., "distributed wind"). Because of a lack of distributed wind-specific valuation studies, in this review we document the current state of distributed energy resource valuation, analyze a wide array of distributed energy resource valuation metastudies, and identify several value elements for which we recommend developing more robust and standardized calculation methodologies for their potential inclusion in distributed wind valuation. These value elements are ancillary services and locational, resilience, reliability, and resource diversity benefits. This work lays the foundation for a future comprehensive framework for distributed wind valuation studies. • Detailed review of current state of DER valuation. • First specific examination of valuation of wind as a distributed energy resource. • Identification of important value elements for distributed wind valuation.
