the renewables portfolio standard in texas an early assessment texas has rapidly emerged as one of the leading wind power markets in the united states this development can be largely traced to a well designed and carefully implemented renewables portfolio standard rps the rps is a new policy mechanism that has received increasing attention as an attractive approach to support renewable power generation though replacing existing renewable energy policies with an as of yet untested approach in the rps is risky early experience from texas suggests that an rps can effectively spur renewables development and encourage competition among renewable energy producers initial rps targets in texas were well exceeded by the end of 2001 with 915 mw of wind installed in that year alone rps compliance costs appear negligible with new wind projects reportedly contracted for well under 3 us cent k wh in part as a result of a 1 7 us cent kwh production tax credit an outstanding wind resource and an rps that is sizable enough to drive project economies of scale obliged retail suppliers have been willing to enter into long term contracts with renewable generators reducing important risks for both the developer and the retail supplier finally the country s first comprehensive renewable energy certificate program has been put into place to monitor and track rps compliance c 2002 published by elsevier science ltd less

an analysis of feed in tariff remuneration models implications for renewable energy investment recent experience from around the world suggests that feed in tariffs fits are the most effective policy to encourage the rapid and sustained deployment of renewable energy there are several different ways to structure a fit policy each with its own strengths and weaknesses this paper presents an overview of seven different ways to structure the remuneration of a fit policy divided into two broad categories those in which remuneration is dependent on the electricity price and those that remain independent from it this paper examines the advantages and disadvantages of these different fit models and concludes with an analysis of these design options with a focus on their implications both for investors and for society

cross hedging and forward contract pricing of electricity we consider the problem of an electric power marketer offering a fixed price forward contract to provide electricity that it purchases from a potentially volatile and unpredictable fledgling spot energy market one option for the risk averse marketer who wants to hedge against the spot price volatility is to engage in cross hedging to reduce the contract s profit variance and to determine the forward contract price as a risk adjusted price the sum of a baseline price and a risk premium we show how the marketer can estimate the spot price relationship between two wholesale energy markets for the purpose of cross hedging as well as the optimal hedge and the forward contract s baseline price and risk premium

support systems for the diffusion of renewable energy technologies an investor perspective concern over climate change impacts and the projected depletion of fossil fuels has urged more governments to adopt policies that stimulate the diffusion of renewable energy technologies ret with an increasingly diverse suite of support instruments the question emerges as to which instruments or combinations are able to achieve faster more substantial diffusion results although various support instruments were extensively addressed in policy studies there is still no consensus this is partly because many policy studies take a policy maker approach in comparing support instruments leaving relationships between policy design and policy results as a black box this paper proposes an investor oriented perspective to analyze the diffusion potential of support systems for ret the main argument is that it is not the type of support instrument but rather its risk profitability characteristics that influence investor behavior and the rate of diffusion the two instruments most frequently discussed and compared are the feed in tariff and the quota model the analysis in this paper concludes that policy design is crucial while often feed in tariffs are applauded and quota system feared feed in tariffs may also bring about disappointing diffusion results when poorly designed while quota systems may be also conceived as attractive instruments for independent power producers

european schemes for promoting renewables in liberalised markets abstract the paper describes possibilities and problems for penetration of supply systems based on renewable energy sources in liberalised markets the analysis is based on recent development in eu with different models for support of installations based on renewable energy these include feed in models with guaranteed minimum tariffs tender models for different bands of technologies and green certificates trading models with obligatory consumer quota the paper describes the market situation in selected european countries including germany the uk holland and denmark an eu directive from september 2001 has postponed the decision on a possible harmonisation of promotional models until at least 2005 in order to obtain more practical experience with the different support schemes a critical evaluation is given in this paper of the different models with proposals for a balanced development between environmental and trading concerns it is argued that too much emphasis is presently given to the side of free trade at the expense of long range planning for a sustainable energy development

diffusion of renewable energy technologies in south korea on incorporating their competitive interrelationships renewable energy technologies rets have attracted significant public attention for several reasons the most important being that they are clean alternative energy sources that help reduce greenhouse gas emissions to increase the probability that rets will be successful it is essential to reduce the uncertainty about its adoption with accurate long term demand forecasting this study develops a diffusion model that incorporates the effect of competitive interrelationships among renewable sources to forecast the growth pattern of five rets solar photovoltaic wind power and fuel cell in the electric power sector and solar thermal and geothermal energy in the heating sector the 2 step forecasting procedure is based on the bayus 1993 manage sci 39 11 1319 1333 price function and a diffusion model suggested by hahn et al 1994 marketing sci 13 3 224 247 in an empirical analysis the model is applied to the south korean renewable energy market

project finance and international energy development this paper explores the preference for and the features unique to project finance one of the favoured vehicles for funding energy development our main focus is on the interests of project sponsors commercial banks and host governments inclusion of the latter reflects the fact host governments are often leading participants in primary energy and energy related projects more recently they have come to use limited recourse structures to finance local infrastructure development traditional analyses whilst providing useful insights into the interests of leading project participants are incapable of isolating a single motive or set of motives that can comprehensively account for all of the features common to this form of debt within an options theoretic framework most of these ambiguities are resolved risk management long recognised as one of the primary reasons for choosing project finance over rival debt structures is affirmed as a key explanatory factor on the other hand options pricing theory provides a radically different perspective on how project finance contributes to the realisation of these objectives

the investor specific price of renewable energy project risk a choice experiment with incumbent utilities and institutional investors abstract renewable energy investments in germany have recently soared trebling the output of wind and solar power generation in only ten years while incumbent utilities have lagged behind in terms of investment new entrants have significantly contributed to this growth existing literature has primarily focused on explaining the lethargy of incumbents former investments although there is a growing need to investigate recent investment drivers to secure the necessary power plant capacity at a moderate cost from incumbents and new entrants alike to close this gap a choice experiment involving 1 659 investment choices by 52 european professional investors was conducted in significant contrast to the case with altruistic investors this survey underlines the importance of using financial incentives to attract professional investors given full exposure to electricity price risk incumbent utilities would facilitate projects at a 3 04 risk premium whereas institutional investors demand 6 61 generally incumbent utilities and institutional investors are equally attracted by low risk projects however when risk increases institutional investors are more hesitant to become involved while incumbent utilities confidently navigate these higher risk projects

quantifying economic sustainability implications for free enterprise theory policy and practice article i nfo in a previous paper ulanowicz goerner lietaer and gomez 2009 we combined thermodynamic network and information theoretic measures with research on real life ecosystems to create a generalized quantitative measure of sustainability for any complex matter energy flow system the current paper explores how this metric and its related concepts can be used to provide a new narrative for long term economic health and sustainability based on a system s ability to maintain a crucial balance between two equally essential but complementary factors resilience and efficiency this generic explanation of the network structure needed to maintain long term robustness provides the missing theoretical explanation for what constitutes healthy development and the mathematical means to differentiate it quantitatively from mere growth matching long standing observations of sustainable vitality in natural ecosystems and living organisms the result is a much clearer more accurate understanding of the conditions needed for free enterprise networks to produce the kind of sustainable vitality everyone desires one which enhances and reliably maintains the health and well being of all levels of global civilization as well as the planet

capital budgeting technological innovation and the emerging competitive environment of the electric power industry abstract for most of this century the electric utility industry has operated as a regulated natural monopoly which produced a commodity product in an environment of low technological progress and sold it to a homogeneous captive market given these conditions the primary capital budgeting issues involved the timing of capacity additions and the mix of base load and peaking capacity this relatively simple and stable situation however has been eroded by market regulatory and technological changes as a consequence old embedded capital budgeting approaches are hindering the pursuit of efficiency with respect to the production and distribution of electric energy our purpose in this paper is to assess traditional utility capital budgeting procedures and to explore possibilities for improvement we begin with a review of traditional capital budgeting decision processes next we overview the changes that have emerged over the last two decades and explore capital budgeting processes more appropriate to this early competitive environment finally we project the changes a bit further and explore the capital budgeting techniques that may be useful in an advanced competitive environment

exploring technology diffusion in emerging markets the role of public policy for wind energy abstract this study challenges the implicit assumption of homogeneity in national institutional contexts made in past studies of renewable energy policy we propose that institutional differences matter by focusing on several technology specific and generic policy factors that can foster technology diffusion through private sector activity more specifically we explore perceptions of early adopters in emerging economy contexts using wind park project developers as an example by applying a parsimonious method for our questionnaire as well as qualitative data we make several contributions methodologically we introduce maximum difference scaling to the energy policy domain empirically we identify several public influences on private investment and assess their relative importance this leads to new insights challenging findings from industrialized economies we identified additional institutional barriers to diffusion hence the requirement of a combination of technology specific and generic policy measures

comparing carbon capture and storage ccs with concentrating solar power csp potentials costs risks and barriers abstract coal power coupled with carbon dioxide capture and storage ccs and concentrating solar power csp technologies are often included in the portfolio of climate change mitigation options intended to decarbonize electricity systems both of these technologies can provide baseload electricity are in early stages of maturity and have benefits costs and obstacles we compare and contrast ccs applied to coal fired power plants with csp at present both technologies are more expensive than existing electricity generating options but costs should decrease with large scale deployment especially in the case of csp for ccs technological challenges still remain storage risks must be clarified and regulatory and legal uncertainties remain for csp current challenges include electricity transmission and business models for a rapid and extensive expansion of high voltage transmission lines the need for international cooperation may impede csp expansion in europe

investment in competitive electricity scope for incentive contracts abstract there is considerable interest in investment in electric power but few projects have actually taken off the situation with investor owned plant is that recovery of the total costs of a new power station via tariffs in the usual way is not automatic the difficulty most often is that the investor and the host system or government need to negotiate on issues such as long term energy pricing the rate of return risk sharing and long term guarantees this paper argues that incentive contracts incorporating risk sharing parameters whose values are set to account for perceptions of risk magnitude and the degree of willingness to take risk are a promising approach to the problem the scope of incentive power contracts the spatial relationship between return and parameters and the methods of deciding parameter values are discussed

measuring global oil trade dependencies an application of the point wise mutual information method abstract oil trade is one of the most vital networks in the global economy in this paper we analyze the 1998 2012 oil trade networks using the point wise mutual information pmi method and determine the pairwise trade preferences and dependencies using examples of the usa s trade partners this research demonstrates the usefulness of the pmi method as an additional methodological tool to evaluate the outcomes from countries decisions to engage in preferred trading partners a positive pmi value indicates trade preference where trade is larger than would be expected for example in 2012 the usa imported 2 548 7 kbpd despite an expected 358 5 kbpd of oil from canada conversely a negative pmi value indicates trade dis preference where the amount of trade is smaller than what would be expected for example the 15 year average of annual pmi between saudi arabia and the u s a is 0 130 and between russia and the usa 1 596 we reflect the three primary reasons of discrepancies between actual and neutral model trade can be related to position price and politics the pmi can quantify the political success or failure of trade preferences and can more accurately account temporal variation of interdependencies

financing energy projects experience of the international finance corporation this paper provides an overview of the recent trend towards private ownership and financing of power projects in the developing countries focusing on the role played by both private and public agencies in meeting the large financing challenges the paper draws upon the operational experience of the international finance corporation which has been involved in the financing of more than 30 private power projects in the developing countries over the past three decades among the issues that affect implementation of private power projects is the balancing of risk and reward to equity investors and to commercial lenders the paper discusses the principal sources of risk and the strategies used to manage them a related issue is the competition for capital on the international markets and the techniques that are being devised to bring more finance to the power sector finally the paper considers the role of government in bringing private investors to the power sector and the approaches being adopted to balance the needs of investors with the needs of the public

biomass power exploring the diffusion challenges in spain the use of biomass resources for power generation offers numerous benefits of interest for political decision makers fuel security rural and industrial development ecological benefits in spain policy instruments have been used since 1980 to stimulate biomass power generation however the diffusion outcome by 2007 was very disappointing only 525 mw this paper argues that two factors lie at the core of this the conceptualization of biomass resources by political decision makers in the instruments used and the desire that policy instruments be in line with market liberalization principles these generated a persistent economic obstacle for biomass power generation and impeded the development of markets for the supply of biomass resources the policy learning regarding the heterogeneity of biomass resources and the investors expectations on risks profitability and resource markets was very slow among political decision makers the paper contributes to the understanding of diffusion outcomes by proposing to analyse diffusion by means of five indicators types of resources technologies developers motivations to invest and project sizes besides the paper shows the usefulness of investigating policy instruments in terms of their risk and profitability characteristics this enables a better understanding of the diffusion patterns and outcomes

do deployment policies pick technologies by not picking applications a simulation of investment decisions in technologies with multiple applications abstract the role of deployment policies that aim to foster technological change has grown considerably especially in the fields of energy and climate however recent research has shown that the adoption of deployment policies carries the potential of locking in the technology that is most cost effective at the point of policy introduction but may be inefficient in the long term the present paper contributes to the emerging literature on the role of deployment policies in creating path dependency and eventually technology lock in while previous studies focused on the relationship between lock in and the technology specificity of deployment policies this paper introduces a new factor the existence of multiple applications for a technology we argue that this factor is highly relevant for technological lock in and should be considered by policy makers to support our argument we simulate the competition among four stationary battery technologies across energy system applications in an investment simulation model this simulation shows that the degree of competition among technologies differs strongly across applications which corresponds with a highly varying lock in probability hence selecting applications in deployment policies very likely corresponds to selecting technologies we discuss the implications of these results for both policy makers and for the academic debate on deployment policies and technological lock in as well as on technology assessment and governance more generally based on the notion that policies can have different technology specificity levels we develop the idea of the application specificity of policies and provide examples of currently enacted deployment policies that vary in terms of their technology and application specificity

motives to adopt renewable electricity technologies evidence from sweden the diffusion of renewable electricity technologies rets has to speed up for countries to reach their often ambitious targets for renewable energy generation this requires a large number of actors including individuals companies and other organizations to adopt rets policies will most likely be needed to induce adoption but there is limited knowledge about what motivates ret adoption the purpose of this paper is to complement and expand the available empirical evidence regarding motives to adopt rets through a survey to over 600 ret adopters in sweden the main finding of the study is that there are many different motives to adopt rets and that ret adopters are a heterogeneous group with regard to motives although environmental concerns interest in the technology access to an re resource and prospects to generate economic revenues are important motives in general adopters differ with regard to how large importance they attach to the same motive and each adopter can also have several different motives to adopt there are also differences in motives between adopter categories especially independent power producers vs individuals and diversified companies and between rets especially wind power vs solar power this implies that a variety of policy instruments might be needed to induce further adoption of a variety of rets by a variety of adopter categories

renewable energy certificate mechanism in india a preliminary assessment abstract the indian national action plan for climate change napcc envisages several measures to address global climate change one of the important measures identified involves increasing the share of renewable energy in total electricity consumption in the country this would mean napcc envisages renewable energy to constitute approximately 15 of the energy mix of india by 2020 to achieve the target set by the napcc indian ministry of power launched renewable energy certificate rec mechanism in november 2010 however participation in the rec markets is low and recs have failed to attract significant investment so far in this study a preliminary attempt has been made to assess the performance of existing rec mechanism in india after highlighting the salient features of the indian renewable energy policy framework a brief description of renewable purchase obligation rpo and source specific rpos for different states is discussed along with an overview of rec market in india to date the performance of indian rec mechanism is evaluated by cost competiveness decentralized distributed generation and renewable energy portfolio diversity and their effectiveness has also been measured on the basis of the available data although it is difficult to make any conclusive remark on the success or failure of rec mechanism due to its short experience this study examines the process to date to come out with some recommendations which can be used to fine tune the functioning of existing rec market in india for instance rec price bounds should be revised because it has been not explicitly supporting cost competiveness by offering 60 33 higher average price than the existing average feed in tariff fit it is also observed that state wise contribution in registered capacity is skewed towards few states like tamil nadu 27 maharashtra 23 and uttar pradesh 22 which puts pressure on policy makers to restructure the existing rec mechanism

the production tax credit for wind turbine powerplants is an ineffective incentive abstract the us energy policy act epact of 1992 created a production tax credit of 1 5 kwh available for 10 years to promote certain renewable energy technologies including wind turbines this paper argues that the impact of the wind turbine production tax credit will be minimal the argument depends entirely on the nature of the project finance structure used by the private power industry for wind turbine development we show that tax credits can only be absorbed by equity investors if there is a large fraction of equity in the project capital structure this raises the financing cost of wind turbine projects compared to conventional power technology which relies on a large fraction of low cost debt if the tax credit were paid as a cash subsidy the capital structure could be shifted to low cost debt and financing costs could be significantly reduced

a historical review of promotion strategies for electricity from renewable energy sources in eu countries abstract the core objective of this paper is to elaborate on historically implemented promotion strategies of renewable energy sources and the associated deployment within the european electricity market hence at a first glance the historic development of renewable energy sources in the electricity res e sector is addressed on member state and on sectoral level as well as consequently discussed according to available res e potentials and costs the specific focus of this paper are promotion strategies for res e options as they are the key driver of an efficient and effective res e deployment therefore the paper depicts the main types of different promotion schemes and their properties additionally several cases studies of different european member states show an in depth analysis of the different res e promotion schemes in this context special emphasises are put on the question of effective and efficient promotion scheme designs of different res e technologies generally conducted research led to the conclusion that technology specific financial support measures of res e performed much more effective and efficient than others did hence it is not all about the common question of feed in tariffs vs quota systems based on tradable green certificates but more about the design criteria of implemented res e support schemes

a critique of renewables policy in the uk the contribution of renewables to the reduction of co2 emissions is hampered by the operation of neta in two ways by its reflection of the high balancing costs within the context of the existing generation and network capacity and the scarcity of long term contracts in traded markets the government s approach of imposing contracts through the renewables obligation is inferior to the development of a carbon tax and risks picking winners from existing technologies rather than exploiting the full range of options

are renewable energy subsidies effective evidence from europe abstract we test if policy support for renewable electricity have been effective in promoting renewables in the five largest european countries in the period 2000 2010 we collect data on the exact amount of monetary incentives and the average tariffs granted the econometric analysis reveals a positive correlation between subsidies and the production of incentivized energy as well as the installed capacity we find that a 1 1c increase in the incentive tariff leads to an increase in renewable generation of 0 4 1 18 26 feed in tariffs appear to outperform tradable green certificates overall the analysis shows that these policies have been effective in promoting renewable energy both in the short and in the long run

cyclical delay in bargaining with externalities externalities between buyers are shown to induce delays in negotiations between a seller and several buyers delays arise in a perfect and complete information setting with random matching even when there is no deadline while with a deadline we identify delays both for positive and negative externalities without a deadline we find that 1 when externalities are positive there exists no spne in pure strategies with bounded recall that exhibits delay 2 when externalities are negative it may happen that all spne with bounded recall have the property that long periods of waiting alternate with short periods of activity this is the cyclical delay phenomenon

fixed feed in tariff versus premium a review of the current spanish system a b s t r a c t since 1998 the spanish government established a feed in system where res e generators could choose between two alternatives fixed feed in tariff and premium nowadays all res e 1 can be sold in the electricity market getting an additional premium except for solar photovoltaic one important novelty established in 2007 is a cap and floor system for facilities under the premium option the aim of this paper is to analyze and compare these two alternative options fixed fit and premiums which coexist at the same time in spain describe the evolution of both systems and evaluate its performance the introduction of this support system in spain led to very good results in terms of res e deployment the main advantage of the premium option is that it is a scheme integrated in the electricity market one disadvantage is that it can occasionally lead to overcompensation one way to try to avoid it is to set a cap value in order to evaluate the performance of this dual support system not only res e deployment has been assessed but also the policy stability the adequacy of res e production to the electricity demand pattern and the changes in the investors behaviour

the social efficiency of instruments of promotion of renewable energies a transaction cost perspective this paper compares the social efficiency of the regulatory instruments used to promote renewable energy sources in electricity generation taking into consideration their role in promoting the preservation of collective goods they are based on a purchase obligation and act either by price feed in tariffs or by quantity bidding for new res e capacities res e quotas from the public economics perspective the two instruments are distinct in terms of cost efficacy and market incentives in a world of imperfect information exchangeable quotas of green certificates are preferred because this instrument allows better control over consumer costs and whilst retaining market incentives transaction cost economics tce contributes to the assessment of these instruments by introducing res e investment safeguard as a major determinant of social efficiency and the instruments conformity to its institutional environment as a determinant of its viability in light of this additional consideration the arrangements between res e producers and obligated buyers inherent in each instrument are in fact quite similar either long term contracting or vertical integration we compare and assess res e price and quantity instruments on several dimensions from both the public economics and tce perspectives control of the cost for consumers safeguards of res e investments adaptability of the instrument in order to preserve its stability in the long run market incentive intensity and conformity with the new market regime of electricity industry it shows neither instruments offer an optimal solution in each of these dimensions the government will thus select an instrument in accordance with the relative importance of its objectives c 2006 elsevier b v all rights reserved

solar feed in tariffs in a post grid parity world the role of risk investor diversity and business models over the past decade feed in tariffs have spurred significant deployment of solar photovoltaics in germany and other countries with recent cost trends several countries are approaching retail grid parity some policymakers conclude that now is the time to remove feed in tariffs as grid parity creates a self sustaining market where economically rational investors will invest even in the absence of government incentives recent experience in key european solar markets however shows that with the advent of grid parity and the reduction of feed in tariffs investment in new solar capacity has decreased rather than increased making it questionable whether low carbon energy policy targets will be reached we conduct a cross case study analysis of three pv markets germany italy and switzerland to investigate the role of feed in tariffs for the near and post grid parity stages of diffusion accounting for investor diversity and distinguishing between implications for revenue based and savings based business models we find that recent market trends are strongly driven by increased levels of risk especially policy risk and exposure to revenue risk we therefore suggest that relatively frugal but stable policy environments may be conducive to further growth of investment in photovoltaics and minimize cost to society

renewable deployment in india financing costs and implications for policy india s ambitious goals for renewable energy raise many questions regarding the nature of investment required we conduct financial modeling of actual renewable projects in india and derive the following insights first the high cost of debt is the most pressing problem higher cost and inferior terms of debt in india may raise the cost of renewable energy by 24 32 compared to the u s second even if cost of debt goes down loan terms including short tenors and variable interest rates will become significant impediments given that they add 13 14 to the cost of renewable energy in india compared to the u s finally due to the high cost of debt policy lessons from the u s and europe which focus on finer instruments such as duration of revenue support revenue certainty investor risk perception and completion cost certainty are not likely to be as effective with potential impacts on the cost of renewable energy in the 3 11 range in fact we find that an interest rate subsidy which reduces the cost of debt reduces the overall subsidy burden by 13 16 this suggests that indian policymakers need to prioritize the provision of low cost long term debt and take a closer look at the successful efforts by china and brazil 2013 elsevier ltd

renewable electricity support systems are feed in systems taking the lead abstract support systems for renewable energy sourced electricity res e can be classified into price and quantity based systems their most representative instruments are feed in systems price based and quota systems e g green certificates or a renewable portfolio standard quantity based the origins of these support systems are quite different and are motivated by different political and economic needs likewise their geographical distribution and effectiveness also differ worldwide feed in systems are the most widespread res e support system in recent years some classical quota countries have partially or even totally changed to feed in systems feed in systems seem to encourage higher res e deployment technology diversity and investor security although the manufacturing capacity for certain res e technologies has been more developed in some feed in countries lately this has changed to some extent due to the incorporation of emerging countries in the res e industry traditionally quota systems appeared to be more compatible with liberalisation of the electricity market however since the introduction of the premium system this argument can be countered since feed in premiums can be considered compatible with the electricity market as quota systems regarding the price paid for res e in quota countries higher green certificate prices have not led to higher res e quantities moreover the relative support levels in quota countries are higher on average than in fit countries contradicting the common argument that quota systems are more cost effective additionally feed in systems especially if stepped tariffs are designed encourage higher res e geographical dispersion avoiding the concentration of res e facilities in just a few locations which can lead to nimby not in my back yard syndrome all these factors may explain the steady spread of feed in systems worldwide the purpose of this paper is to assess the performance of quota and feed in systems thereby contributing to the worldwide debate on the suitability of the different res e support systems

strategic choices for renewable energy investment conceptual framework and opportunities for further research this paper introduces the special issue on strategic choices for renewable energy investment which is a collection of best papers presented at an international research conference held in st gallen switzerland in february 2010 substantial private investment is needed if public policy objectives to increase the share of renewable energy and prevent dangerous anthropogenic climate change are to be achieved the aim of this paper and the entire special issue is to draw scholarly attention to the processes underlying strategic choices for renewable energy investment and how they are influenced by energy policy we disentangle the role of risk return perceptions portfolio effects and path dependence in explaining energy investment decisions and suggest that the heterogeneous universe of investors requires a segmentation of policies the paper outlines some of the rich opportunities for further research in this emerging area

the renewable portfolio standard design considerations and an implementation survey renewables have social and environmental bene ts compared to conventional electricity sources but are rarely competitive on a strict nancial cost basis this is because conventional sources are sometimes subsidized their full pollution costs are ignored and renewables involve newer higher cost technologies whose relative costs will fall with commercialization governments use several mechanisms to support renewables including direct nancial support grants loans indirect support r d demonstrations reform of nancial costs of conventional sources subsidy removal pollution taxes and the renewable portfolio standard rps the rps requires a minimum share of electricity from renewable energy sources its use is spreading because it maintains an incentive for renewable producers to reduce costs links the regulated market outcome to an environmental target and reduces government involvement although it is too early to evaluate fully its e ectiveness the survey for this study explored implementation issues in three european countries nine us states and australia and found the following the rps target is usually set to have environmental bene ts without causing signi cant price increases cost caps are sometimes used most jurisdictions limit eligibility to gridconnected domestic renewables the rps is usually applied to producers rather than consumers and to energy output not capacity flexibility mechanisms are desired but a challenge to implement administration in the us and australia is by government with delegation to independent utility regulators while in europe it is more the responsibility of government everywhere the rps is applied alongside other mechanisms of renewables support 2001 elsevier science ltd all rights reserved

policies to accelerate the growth of offshore wind energy sector in india abstract india s power generation capacity needs to be augmented to support the growing demands for electricity india which has predominantly used fossil fuels to power its generators need to make a switch to clean energy fuels but renewable sources form a miniscule portion 26 gw 12 of india s overall installed power capacity 210 gw there is no contribution from offshore wind farms to the energy basket for india as there is no policy framework to encourage the development of offshore wind farms several european countries have tapped the offshore wind energy potential to reduce their dependence on adopted by these countries to identify the core components 21 of them of robust policy intervention a detailed questionnaire was administered to 181 stakeholders of wind energy in india to seek their feedback on these building blocks these core components variables in research parlance are then subjected to factor analysis to understand the underlying structure of the variables the factor analysis logically reduces these 21 variables into five factors government support fiscal and quota based incentives availability of local expertise capital for investments and building an enabling r d ecosystem which are then fed into a logistic regression model as independent variables to predict the probability of growth of offshore wind energy dependent variable in the country the logistic regression model gives the weight the impact of these independent variables in influencing the growth of offshore wind energy in india it emerges that government support fiscal and quota based incentives and building an enabling r d ecosystem have a much higher impact on the growth of offshore wind energy for india this paper fills the gap of absence of an empirically tested framework on offshore wind energy policy for india

constructing a network of the social economic consumption system of china using extended exergy analysis abstract the prominent conflict between consumption and environmental resources is acknowledged as a significant force in affecting the social ecological community balance the whole process of resource allocation utilization efficiency and outcome are crucial clues in uncovering the structural and functional characteristics in complex consuming systems herein network relationship provides a system oriented modeling technique for examining the structure as well as flow of materials or energy from an input output perspective meanwhile extended exergy the only currently available thermodynamic based metric for social economic environmental impacts associated with energy consumption manpower and monetary operation as well as environmental emission is an extension of the labor theory of value and a possible sustainability metric the core purpose of this research is to construct a network of the social economic consumption system of china using extended exergy analysis to explain the interrelationship among different sectors within a thermodynamic metric therefore we firstly make a database of extended exergy accounting in the chinese consumption system data are available for 2007 which can be divided into seven sectors based on the reclassification of the regularly published 42 sector input output table namely 1 agriculture 2 extraction 3 conversion 4 industry 5 transportation 6 tertiary and 7 domestic sectors then we will construct an extended exergy network to gain insight into the thermodynamic distribution within sectoral criterion lastly the network results and indicator analysis are explained for china s social metabolism maintained by a large quantity of energy resources and labor as well as the environmental costs within an exergy foundation

what are retail investors risk return preferences towards renewable energy projects a choice experiment in germany citizens own nearly half the renewable energy generation capacity in germany and have been important drivers of the country s energy transition in contrast to citizens important role in financing renewable energies the energy policy and economics literature has traditionally focused on other investors such as incumbent energy firms to close this gap this paper reports on a large scale survey of 1 990 german retail investors conducting a choice experiment with the subset of 1 041 respondents who expressed an interest in investing in community renewable energy projects we present a unique dataset allowing for new insights in risk return expectations of retail investors we find that apart from return on investment respondents are particularly sensitive to the minimum holding period and the issuer of community renewable energy investment offerings a minimum holding period of 10 years implies a risk premium of 2 76 points a subsequent segmentation analysis shows that two groups of potential community renewable energy investors with different risk return expectations can be identified local patriots and yield investors in contrast to professional investors a majority of retail investors use simple decision rules such as calculating payback time or relying on their gut feeling when making investments

new directions in electric power financing this paper argues that it is necessary to raise the eyes from the current focus on independent power projects buttressed by guarantees to the longer horizon of electric power financing in open markets transitional strategies will need to move beyond the commonly seen ipp activity that occurs without fundamental sector reform and demand side incentives that introduce further market distortions these efforts will have to focus on macroeconomic stabilization removal of price distortions as well as sector and corporate reform mobilization of domestic capital will be essential for sustainable sector financing although guarantees to encourage power sector investment can be designed to selectively cover risks their elimination through fundamental sector reform should be the ultimate goal over the longer term traditional corporate finance should become a more common financing strategy than project finance innovations in performance risk management and consumer credit will be crucial to the financing of energy efficiency

the effect of local and global learning on the cost of renewable energy in developing countries high upfront costs are a critical barrier for investments in clean infrastructure technologies in developing countries this paper uses a case study of thailand s electricity sector to create realistic estimates for the relative contributions of local and global technological learning to reducing these cost in the future and discusses implications of such learnings for international climate policy for six renewable electricity technologies we derive estimates for the share of locally and globally sourced goods and services and analyze the effects of local and global learning during the implementation of thailand s renewable energy targets for 2021 our results suggest that in aggregate the largest potential for cost reduction lies in local learning this finding lends quantitative support to the argument that the conditions enabling local learning such as a skilled workforce a stable regulatory framework and the establishment of sustainable business models have a more significant impact on cost of renewable energy in developing countries than global technology learning curves the recent shift of international support under the united nations framework convention on climate change towards country specific technology support is therefore promising however our results also show that the relative importance of local and global learning differs significantly between technologies and is determined by technology and country characteristics this suggests that international support need to consider both the global perspective and local context and framework conditions in order to reap the full benefits of technological learning across the wide range of clean technologies

national natural capital accounting with the ecological footprint concept abstract there is a growing consensus among natural and social scientists that sustainability depends on maintaining natural capital however progress to put this ecological condition to practice has been slow not least because of the inability of making these objectives measurable therefore to overcome this obstacle assessment frameworks for natural capital are needed this study presents a simple framework for national and global natural capital accounting it demonstrates using the example of italy an accounting framework which tracks national economies energy and resource throughput and translates them into biologically productive areas necessary to produce these flows this calculation has been applied to over 52 countries with this framework based on the ecological footprint concept human consumption can be compared with natural capital production at the global and national level using existing data

the financing of the mexican electrical sector abstract this paper analyses the financial pattern of the mexican electricity sector its financial limits in both development and modernization of this strategic sector and the main options for resolving this financing problem including the proposals of the president fox government our allocation of risks and profitability analysis explain the present success in attracting private investments to expand both generation and transmission capacity through blt and ipp projects the financial limitation is nevertheless the low self financing of federal electricity commission cfe that will make it very difficult to obtain financing to fulfil blt and ipp contract compromises and to invest large sums in the expansion and modernization of the electricity sector the main options to resolve the financial problems of the mexican electricity sector are 1 the improvement of the present financial pattern 2 the opening of generation and supply segments to private capital with the preservation of the vertically integrated state owned utilities and 3 the proposals of the president fox economic transition team that consider the opening of generation and supply segments the setting up of an independent state owned company to operate both the electrical dispatching and a power pool and finally the transformation of cfe into a holding of state owned utilities of generation distribution and transmission

financial risks for green electricity investors and producers in a tradable green certificate market this paper analyzes financial risks in a market for tradable green certificates tgc from two perspectives existing renewable producers and potential investors in new renewable electricity generation capacity the equilibrium pricing mechanism for a consumer based tgc market is described and a market with wind turbines as the sole renewable technology is analyzed in this framework tgc prices and fluctuations in production from wind turbines will be negatively correlated and as a result tgc price fluctuations can actually help decrease the total financial risk based on this recognition analytical expressions for revenue variance minimizing trading strategies are derived and an analysis of the demand and supply for financial hedging is used to show that forward contracts will be traded at a risk premium

small streams diverse sources who invests in renewable energy in finland during the financial downturn this article addresses the investment gap in renewable energy sources identified by several authors examining the case of a country finland which introduced policy measures to diversify its renewable energy portfolio we analyse the development of investments in renewable heat and power in response to new policy measures and contextual factors during the downturn period 2009 2013 we investigate investor heterogeneity i e the diversity of logics employed by different types of res investors in spite of a severe financial recession we find an emergence of new sources of investment among these new investor types we find diversity in investment drivers and available options these include investors mobilized by the feed in tariff to seek profitable targets and investors such as real estate owners investing in heat pumps for their own use and benefiting from low interest rates we find that the diversification of investors supports the diversification in res sources and brings in new investors undeterred by the financial downturn our findings imply that policy makers should recognize that the responses to distinct incentives and pressures vary by investor types this also means that a mix of policies is required to maximize the contribution of different sectors to filling the renewable energy investment gap

the price of policy risk empirical insights from choice experiments with european photovoltaic project developers managing the transition to a renewable energy future is an important policy priority in many countries solar photovoltaic pv technology is expected to make an important contribution but due to relatively higher cost its growth to date has been largely driven by public policy notably feed in tariffs feed in tariffs have been implemented in various countries however with widely differing outcomes in terms of installed pv capacity previous research indicates that the level of policy risk may be an important driver for differences in renewable energy policy effectiveness more specifically we suggest that investors who take a decision between pv investment opportunities in different countries carefully weigh feed in tariff induced returns against a set of policy risks and choose the country with the most favorable risk return profile we empirically test this model based on a stated preference survey among european pv project developers consisting of 1575 choice decisions by 63 investors the findings of our study demonstrate that risk matters in pv policy design and that a price tag can be attached to specific policy risks such as the duration of administrative processes or uncertainty induced by an approaching capacity cap governments can build on our empirical results to design policies that will be effective in attracting private pv investment while at the same time maintaining efficiency by providing an adequate compensation for policy risk

factors influencing the likelihood of regulatory changes in renewable electricity policies abstract the renewable electricity literature has expanded in recent years from the analysis of policies focused on research and development rd the coherence of the policies the size and variety of the coalitions supporting and opposing renewable electricity and the brussels effect the importance of these factors is evaluated in the case of three major markets of renewable electricity germany the netherlands and denmark

avoided cost contracts can undermine least cost planning abstract utilities and regulatory agencies are increasingly turning to non utility sources of electric power in the usa many contracts with independent power producers ipps contain indexing terms under which an ipp s energy rates vary in response to energy cost changes on the purchasing utility system such indexing is often used to ensure that ipp rates track utility avoided costs unfortunately such indexing can undermine least cost planning if utility decisions can alter established ipp rates such indexing can also cause ratepayer interests to conflict with those of society the use of regional cost indices can solve the utility planning problem preventing the conflict between ratepayers and society however may require some use of cost based rather than value based ratemaking for ipps

an assessment of the greek incentives scheme for photovoltaics abstract after two years of elaboration a new legislation was enacted in 2006 in greece providing an appealing feed in tariff fit scheme for photovoltaics pvs the response of the market was immediate with more than 7947 licenses having been submitted in less than 2 years time the effectiveness however of an incentives scheme cannot be judged solely by the response of prospective investors aim of this paper is to present and discuss a quantitative assessment of this newly introduced fit law in greece with respect to its attractiveness to investors its effectiveness towards launching a new market its cost efficiency and its ability to lift non economic barriers that led to significant delays in the diffusion of res over the last 10 years

interdependence between energy and metals in china evidence from a nexus perspective abstract the lack of knowledge about the interdependence between energy and metals hinders sustainable management of the two essential resources in this study a hybrid framework which combines the environmentally extended input output analysis eeioa and ecological network analysis ena was constructed to evaluate energy metals use and flows within china s economic system in 2012 from the perspective of nexus furthermore the structural properties of nexus networks and mutual relationships between sectors were simultaneously explored the results show that hybrid energy direct energy metals related energy and hybrid metals direct metals energy related metals used by all the sectors were 1 22 and 1 05 times their direct energy and direct metals use respectively in both hybrid energy and metal networks mining industry and construction industry had a strong control and dependence relationship over 50 with other sectors reflecting the tight inter sectoral connection between energy use and metals use therefore stabilizing these main control and dependence pathways is essential to the system s effective operation in addition alleviating excess industrial capacity and optimizing economic structure are two effective measures to improve the currently low energy metals circulation efficiency within china s economy system by revealing the nexus between energy and metals in china this study provides important policy implications for trade offs and synergies between energy and metals use

fair trade and harmonization of climate change policies in europe abstract in march 2000 the european commission presented a green paper on greenhouse gas emissions trading within europe supporting implementation of a community wide scheme in which the design and regulation of all essential elements would be harmonized at the community level the present paper analyzes economic arguments used to justify such a coordinated scenario showing these arguments to be based on misleading rhetoric about fair trade and harmonization diverse allocations of emissions allowances across member states are justified in theory in practice too no empirical evidence or model based results demonstrate that an uncoordinated european trading scheme would adversely affect competitiveness to any significant extent or substantially increase industrial relocations

quantifying the sustainability of economic resource networks an ecological information based approach abstract sustainability as a concept has multiple disparate perspectives stemming from different related disciplines which either maintain ambiguous interpretations or concentrate on metrics pertaining to single aspects of a system given the embedded multi dimensionality of sustainability systemic approaches are needed that can cope with interactions of different dimensions past efforts for measuring sustainability holistically have taken an accounting approach based on the availability and efficiency of resource flows however an accounting approach fails to fully incorporate the intensive parameters pertaining to sustainability an ecological information based approach is a promising holistic measurement which incorporates both intensive and extensive dimensions of sustainability this paper evaluates this approach by applying it to six economic resource trade flow networks virtual water oil world commodity oecd bric commodity oecd bric foreign direct investment and iron and steel from the perspective of biomimicry it appears that these networks can achieve higher levels of efficiency without weakening their robustness to resource delivery the trends of measured efficiency and redundancy of the studied networks are demonstrated to be useful in reflecting long term changes while the trend in robustness levels were found to exhibit similar behavior to an ecosystem in its early phase of development

the public promotion of wind energy in spain from the transaction costs perspective 1986 2007 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

the effect of financial constraints technological progress and long term contracts on tradable green certificates tradable green certificates tgcs have recently become a diffuse instrument to support renewable electricity in oecd countries although it is perhaps too early to draw a conclusive judgement on the effectiveness of this instrument in increasing renewable capacity and decreasing the price of certificates one view in the literature maintains that long term contracts are of particular importance for tgcs to be effective this paper contributes to this debate by analysing how financial constraints and technological progress can induce investors to hold pessimistic expectations of their ability to sell green certificates and still make a profit clearly these expectations will prevent investors from building new capacity to fulfil the quota comprised in tgcs and will keep the price of certificates traded in the market high as this kind of expectation is not influenced by most design features of tgcs one can conclude that long term contracts are particularly important in determining the effectiveness and cost effectiveness of these instruments some attention should therefore be paid to the features of the tgcs which induce obliged parties to offer long term contracts to renewable generators

public policy influence on renewable energy investments a panel data study across oecd countries this paper examines the impact of public policy measures on renewable energy re investments in electricity generating capacity made by institutional investors using a novel combination of datasets and a longitudinal research design we investigate the influence of different policy measures in a sample of oecd countries to suggest an effective policy mix which could tackle failures in the market for clean energy the results call for technology specific policies which take into account actual market conditions and technology maturity to improve the conditions for institutional investments advisable policy instruments include economic and fiscal incentives such as feed in tariffs fit especially for less mature technologies additionally market based instruments such as greenhouse gas ghg emission trading systems for mature technologies should be included these policy measures directly impact the risk and return structure of re projects supplementing these with regulatory measures such as codes and standards e g rps and long term strategic planning could further strengthen the context for re investments

the role of regulatory uncertainty in certificate markets a case study of the swedish norwegian market abstract price volatility in green certificate markets reflects uncertainty over future prices representing a major source of risk for renewable energy generators price risk is considered the principal deficiency of this market based policy since it causes investors to require higher returns moreover investors are exposed to regulatory risk namely the risk that a change in the regulation will materially impact the certificate price regulatory uncertainty is reflected in market volatility exacerbating certificate price risk using an econometric approach we investigate the role of regulatory changes on price volatility in the swedish certificate market the results of our analysis indicate that regulatory changes strongly affect certificate markets resulting in periods of higher volatility moreover we analyze whether certificate price volatility has changed after creating a joint swedish norwegian market results indicate that the ambivalence surrounding the creation of this bigger market led to a period of increased price volatility between 2010 and 2011 overall this article brings a better understanding of the role of regulatory uncertainty on certificate markets and gives evidence for its negative impact in terms of increased price volatility

financing the energy sector in developing countries context and overview abstract traditional business as usual financing methods will no longer be adequate to meet the unprecedented demands for capital to finance energy sector expansion in the developing countries in recognition many countries are opening up their power sectors to private investment initially through the establishment of independent power projects but in some cases through sector privatization project financing has many advantages but further sectoral reorganization including tariff reform will be needed to attract resources on the scale required especially from domestic investors in oil and gas in contrast to power private capital from the international oil companies has always played a major role in the developing countries however sharply increasing investment requirements require a growing role for external finance there should in principle be no shortage of investible funds to finance energy sector expansion in developing countries so long as host countries establish conditions which are attractive to private investors the augmented role of private finance requires a continuing if different role for the public sector in both host countries and official aid agencies

renewable electricity production costs a framework to assist policy makers decisions on price support abstract despite recent progress the production costs for renewable electricity remain above those for conventional power expectations of continuous reductions in production costs typically underpin governments policies for financial support they often draw on the technology focused versions of the experience curve model this paper discusses how national contextual factors also have a strong influence on production costs such as geographic infrastructural institutional and resource factors as technologies mature and as they reach significant levels of diffusion nationally sustained increases in production costs might be recorded due to these nationally contextual factors poorly accounted for in policy making decisions for price support the paper suggests an analytical framework for a more comprehensive understanding of production costs based on this it recommends that the evolution of specific cost levels and factors be monitored to locate sources of changes the paper also suggests policy instruments that governments may use to facilitate cost decreases whenever possible the application of the framework is illustrated for the diffusion of wind power in spain during the past three decades

implementation of wind power in the norwegian market the reason why some of the best wind resources in europe were not utilised by 2010 abstract norway has some of the best wind resources in europe in 1999 the norwegian parliament committed to attain an annual onshore wind power production goal of 3 0 twh by 2010 however in 2010 onshore wind power production measured only 1 0 twh this article discusses the reasons that this goal was not achieved the analysis addresses the key figures on the strategic tactical and operational levels this model is combined with a time line that seeks to define when different actors should have secured concessions 1 and funding to achieve the goal after introducing the time line a list of questions is introduced for these key actors the three level model the time line and the questions constitute the analytical framework explanations for the failure to achieve the goal may be identified on all three levels however the primary explanatory factors were political uncertainty in the support scheme and wind power s role in the energy market in general both of these factors are identified on the strategic level uncertainty on the strategic level influenced the lower levels which led to bottlenecks in the concession process and jittery investors who thought that the risk of investment in wind power was too high

mobilizing private finance for low carbon innovation a systematic review of barriers and solutions this paper analyses the field of innovation studies regarding barriers to low carbon innovation and consequences for finance investment and divestment and contributes to a more holistic understanding of the underlying mechanisms a combination of technological barriers combined with economic barriers institutional and political barriers contribute to sub optimal low carbon investment all along the innovation cycle policy makers need to take a systemic approach to enable the redirection of diverse private financial sources instruments range from cutting dirty r d subsidies and support for clean technology innovation and diffusion levelling the institutional playing field and making risks of high carbon and low carbon technologies transparent to providing a consistent but adaptive long term transition strategy this would allow financiers to gradually shift their investments away from high carbon mainstream markets and scale low carbon technology niche markets however financiers also need to sharpen their competencies with regard to new clean technologies and markets

the paradox effects of uncertainty and flexibility on investment in renewables under governmental support abstract given that companies have the flexibility to decide about size and timing of a renewable electricity investment the existence of four paradox effects is proven only the type but not the amount of governmental support has an influence on the optimal capacity of a renewable electricity generating system a decrease of governmental support over time may result in higher capacities of renewables installed on an industry level at least on the short term likewise higher uncertainty may encourage an expansion of these capacities in contrast technological progress may hamper the expansion of capacities finally these four paradox effects are exemplified in a germany based case study regarding a photovoltaic project

an energy pricing scheme for the diffusion of decentralized renewable technology investment in developing countries the purpose of this paper is to investigate price support for market penetration of renewable energy in developing nations through a decentralized supply process we integrate the new decentralized energy support renewable premium tariff to analyze impacts of tariff incentives on the diffusion of renewable technology in senegal based on photovoltaic and wind technologies and an assessment of renewable energy resources in senegal an optimization technique is combined with a cash flow analysis to investigate investment decisions in renewable energy sector our findings indicate that this support mechanism could strengthen the sustainable deployment of renewable energy in remote areas of senegal although different payoffs emerged profits associated with a renewable premium tariff are the highest among the set of existing payoffs moreover in analyzing impacts of price incentives on social welfare we show that price tariffing schemes must be strategically scrutinized in order to minimize welfare loss associated with price incentives finally we argue that a sustainable promotion of incentive mechanisms supporting deployment of renewable technology in developing nations should be carried out under reliable institutional structures the additional advantage of the proposed methodology is its ability to integrate different stakeholders producers investors and consumers in the planning process

assessment of current dutch energy transition policy instruments for the existing housing stock abstract this research assesses to what extent current dutch energy transition policy instruments for the existing housing stock can fulfil local executive actors needs and instigate adoption of energy efficiency measures by them this is done by studying energy policy instruments for the existing housing stock in the netherlands and in other european countries and by an empirical research which analyses barriers and needs of local executive actors we found that despite current dutch energy transition policy instruments for the existing housing stock seem to fulfil local executive actors needs to a large extent complementary policy instruments are needed to stimulate and pressure the incumbent renovation regime a long term oriented financial rewarding system is needed to build up a structural market for the deployment of renewables to increase the number of specialist jobs in the building sector and to stimulate the development of integrated standardized building components furthermore a long term oriented financial rewarding system for energy efficiency investments in housing renovation projects and a low vat rate applied to energy efficient renovation measures are needed finally enforcement possibilities and sanctions fines should become an integrative part of dutch energy certification regulation to make the certificate become part of a value chain

who invests in renewable electricity production empirical evidence and suggestions for further research transforming energy systems to fulfill the needs of a low carbon economy requires large investments in renewable electricity production res e recent literature underlines the need to take a closer look at the composition of the res e investor group in order to understand the motives and investment processes of different types of investors however existing energy policies generally consider res e investments made on a regional or national level and target investors who evaluate their res e investments according to least cost high profit criteria we present empirical evidence to show that res e investments are made by a heterogeneous group of investors that a variety of investors exist and that their formation varies among the different types of renewable sources this has direct implications for our understanding of the investment process in res e and for the study of motives and driving forces of res e investors we introduce a multi dimensional framework for analyzing differences between categories of investors which not only considers to the standard economic dimension which is predominant in the contemporary energy literature but also considers the entrepreneurship innovation adoption and institutional dimensions the framework emphasizes the influence of four main investor related factors on the investment process which should be studied in future research motives background resources and personal characteristics
