renewable energy for continuous energy sustainability in malaysia abstract demographic change dramatic population increase and rapid industrial growth are major trends emerging in malaysia climate change and depletion of fossil fuel along with the rise in petroleum prices have forced the malaysian government to rethink strategies to be more in line with other developed countries including the decision to embark on renewable energy re resources as a better source of energy amongst the global energy mix the malaysian government is making frantic efforts to make policies re programmes and incentives more effective so as to promote and develop the use of re malaysia is rich with fossil fuel but these are fast depleting although re is necessary current re resources are still not enough therefore exploration into other resources must be considered in order to meet future energy demands the objective of this paper is to identify the potential of available renewable energy resources in malaysia as well as the country s current implementation strategies this paper also discusses the different re policies in malaysia in order to determine the potential of re various sources and published materials in conferences international journals and information released by relevant government bodies and miscellaneous resources are used this research has revealed that among all the renewable energy sources that are present in malaysia biomass and solar energy are the most prospective ones plus renewable energy re sources are quite advantageous as they are free from greenhouse gas ghg emissions and related global warming effects they can also be applied in off grid electricity generation for rural communities

how do learning externalities influence the evaluation of ontario s renewables support policies abstract support programs for renewable electricity generation in ontario have been in place since 2005 including feed in tariffs and a competitive procurement process these programs have been criticized on a number of fronts in particular critics claim the level of support was excessive and creating surplus supply however prior studies have ignored one potential benefit of renewable energy support that it can help to promote cost reductions in new technologies through learning by doing this paper uses a recursive dynamic computable general equilibrium cge model featuring learning by doing effects to assess the renewable support programs provided in ontario our results in line with previous studies do not justify the high support rates paid in ontario given our core range of assumptions but our modeling approach allows us to identify the combination of key parameter values relating to learning effects and environmental damages that justify the observed rates these parameters are hard to measure empirically and our modeling approach introduces a new tool for examining the impact of variations in these parameters on policy analysis

feed in tariffs for promotion of energy storage technologies faster market integration of new energy technologies can be achieved by use of proper support mechanisms that will create favourable market conditions for such technologies the best examples of support mechanisms presented in the last two decades have been the various schemes for the promotion of renewable energy sources res in the eu the most successful supporting schemes are feed in tariffs which have significantly increased utilisation of renewable energy sources in germany spain portugal denmark and many other eu countries despite the successful feed in tariffs for res promotion in many cases res penetration is limited by power system requirements linked to the intermittency of res sources and technical capabilities of grids these problems can be solved by implementation of energy storage technologies like reversible or pumped hydro hydrogen batteries or any other technology that can be used for balancing or dump load in this paper feed in tariffs for various energy storage technologies are discussed along with a proposal for their application in more appropriate regions after successful application on islands and outermost regions energy storage tariffs should be also applied in mainland power systems increased use of energy storage could optimise existing assets on the market

regulation profitability and diffusion of photovoltaic grid connected systems a comparative analysis of germany and spain abstract although both germany and spain were pioneers in the support and adoption of photovoltaics pv through feed in tariffs fits germany is the world s leading country in terms of installed pv capacity per capita and remains on a path of pv growth while the spanish pv market is virtually paralysed we analyse the divergent performance in both countries by reviewing the evolution of fits and by analysing the profitability of different types of installations for the period 2004 2014 while in germany the policies profitability and diffusion of pv were relatively stable over time in spain erratic policy changes and the distortionary effect of the solar orchard ownership structure caused a diffusion bubble june 2007 september 2008 and a subsequent profitability bubble 2009 2011 these bubbles led to the collapse of the support system in 2012 revealing the difficulty inherent in designing innovation and diffusion policies in the context of high uncertainty and rapid technological change

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

the merit order effect of wind and river type hydroelectricity generation on turkish electricity prices abstract the environmental concerns and dependency on gas imports push turkish policy makers to find ways of increasing the share of renewable sources in electricity generation providing incentives for renewable energy in the form of feed in tariffs is one of the measures to achieve this goal basing on the data of turkish electricity market operator we quantified the magnitude of the price effects of wind and river type hydro generations on hourly average of day ahead prices we find that wind and river type hydro plants reduced the spot electricity prices during the period of 2012 2017 and despite these resources get the same incentives their impacts on the spot prices and price volatility are different this can be useful for a more comprehensive cost benefit analysis aimed at differentiating incentive schemes the paper also discusses possible underlying reasons of these different impacts such as high seasonality of hydro generation and volatility of wind generation finally we show that assuming more than 75 of the price reductions were reflected into the consumer prices in turkey the net impact of wind and river type hydro generation on final consumer prices would be negative this finding contributes to the discussions on renewable energy incentive mechanisms

public policy supports and export performance of bioenergy technologies a dynamic panel approach abstract this study investigates the effects of public policy supports on the export performance of bioenergy technologies it uses panel data from 18 countries from the 1992 to 2008 period panel unit root and cointegration tests are applied taking into account the results of structural break tests for each time series and testing for the presence in the panel of cross sectional dependence time series data on public supports and exports are integrated and cointegrated the results of dynamic ordinary least squares indicate that in the long term public r d expenditures have a positive effect on the exports the contribution of bioenergy to the total energy supply has a negative effect on the exports and gdp has a positive effect on the exports the contribution of bioenergy to total energy supply responds to deviations in the previous period from the long term equilibrium additionally blundell bond system generalized methods of moments estimations are made to determine dynamic causality in a panel vector error correction mechanism setting evidence of a positive strong and short term relationship from exports to r d expenditures and of a positive short term causality from exports to the contribution of bioenergy to total energy supply is found a positive strong bidirectional relationship between gdp and exports is also uncovered there is a positive strong bidirectional and short term relationship between gdp and the contribution of bioenergy to total energy supply finally some policy implications based on the results of this study are offered

germany s solar cell promotion dark clouds on the horizon abstract this article demonstrates that the large feed in tariffs currently guaranteed for solar electricity in germany constitute a subsidization regime that threatens to reach a level comparable to that of german hard coal production a notoriously outstanding example of misguided political intervention yet as a consequence of the coexistence of the german renewable energy sources act eeg and the eu emissions trading scheme ets the increased use of renewable energy technologies does not imply any additional emission reductions beyond those already achieved by ets alone similarly disappointing is the net employment balance which is likely to be negative if one takes into account the opportunity cost of this form of solar photovoltaic pv support along the lines of the international energy agency iea 2007 energy policies of iea countries germany 2007 review international energy agency oecd paris p 77 we recommend the immediate and drastic reduction of the magnitude of the feed in tariffs granted for solar based electricity ultimately producing electricity on this basis is among the most expensive greenhouse gas abatement options

feed in tariffs with minimum price guarantees and regulatory uncertainty abstract the feed in tariff fit program is a popular policy for incentivizing new renewable energy projects because it establishes a long term contract with renewable energy investors this paper presents a novel model to analyze a fit contract with a minimum price guarantee i e a price floor regime from an investor s perspective the results show that a perpetual guarantee only induces investment for prices below the price floor when offering a risk free investment opportunity in contrast the finite guarantee may induce investment even when the revenue from the guarantee is lower than the investment cost when an investor faces a scenario with regulatory uncertainty a higher and more likely reduction in the price floor induces earlier investment for all cases investors postpone an investment decision when market conditions present a higher price volatility

extent and types of small scale wind policies in the u s states adoption and effectiveness abstract renewable energy sources including wind are increasingly promoted by u s state governments using state level data and survey responses from energy officials in 44 states this study catalogs the extent and types of small wind policies adopted by states it examines the factors correlated with policy adoption and perceptions about which policy tools are most effective results indicate that 84 of the states participating in the survey have adopted at least one policy to promote small wind technologies and most have adopted several policies the most frequent policy is net metering and this policy tool was also perceived to be one of the most effective at encouraging businesses and consumers to install small wind technologies however several other policy tools perceived to be most effective at promoting small wind installations have been adopted by relatively few states this identified gap suggests opportunities for improving policy effectiveness in explaining factors associated with adoption of policy tools we find support for variables comprising both the policy diffusion and internal determinants models of policy adoption including state commitment to environmental protection and policy innovations citizen ideology per capita wealth energy policy network communications and desire to be viewed as an environmental leader

towards a sustainable electrification in ghana a review of renewable energy deployment policies abstract ghana has been facing perennial power rationing over the years due to fuel supply challenges the country s energy system is likely to suffer additional strain from rising energy demand fueled by population growth rapid urbanization and economic development fortunately there are enormous renewable energy resources which can provide sustainable electrification as backbone to socioeconomic development while curbing global warming ghana s energy strategy targets 100 access to electricity and 10 share of sustainable power in national generation mix by 2020 despite the existence of numerous policies and a renewable energy act current contribution of non conventional renewable energy to electricity generation is less than 1 the right mix of policies to address the unique domestic conditions and achieve its specific development goals remains insufficient this study reviews the regulatory framework financing incentives and other provisions of ghana s renewable energy act it critically examines the policy s strengths weaknesses opportunities and treats based on comparative analysis and lessons drawn from failed and successful implementation of similar policies around the world the study also assesses the impact of policy on project development it was found that the performance of ghana s renewable energy policy on grid connected electricity has been poor compared to its target the fundamental reasons for this unsatisfactory performance may be attributed to partial implementation of policies lack of market driven support schemes lack of pricing policy framework weak grid network limited access to funds and inconsistencies in renewable energy development strategies this study proposes the following countermeasures i ghana should comprehensively harmonize renewable energy regulatory and fiscal policies with domestic electricity pricing regime ii market driven support schemes should be prioritized for cost effectiveness and minimum governmental influence these reforms can help eliminate some of the major barriers to sustainable electrification in ghana while the lessons provide a learning curve for other african countries

solar feed in tariffs examining fair and reasonable retail rates using cost avoidance estimates abstract growing solar photovoltaic pv electricity systems in geographically diverse regions presents a complex policy problem for governments during 2013 16 the queensland government in australia examined establishing a fair and reasonable retail feed in tariff fit policy noting it regulates state retail electricity consumption prices a combined cost avoidance and stakeholder analysis was applied to show that determination of a fair and reasonable fit for all stakeholders while aspirational is difficult to achieve typically agreement on a fair tariff rate will depend on stakeholders relative position in energy supply chains service providers retailers suppliers customers advocates and interpretations of fairness that can be shaped by competition in the supply area also increases in financial benefits to pv customers might be considered unreasonable by non pv customers and retailers that experience increases in electricity prices and operating costs importantly the application of a retail fit in regional and isolated areas requires careful energy policy design taking account of network losses remote and isolated customer metering cost effective network control technologies and diesel generator operating limits the study also observed that shifting funding of fit schemes from electricity distributors to competitive retailers will likely have negative consequences for retail fit offerings and pv customer servicing

renewable energy support mechanisms in the gulf cooperation council states analyzing the feasibility of feed in tariffs and auction mechanisms renewable energy will be a crucial ingredient in the transition to a more sustainable future the renewable energy sector requires a variety of financial support mechanisms in order to further consolidate and expand currently the most prominent renewable energy support mechanisms are feed in tariffs and renewable energy auctions although these mechanisms have been used and analyzed extensively in western countries and more recently economies in transition they have rarely been examined in the arab gulf region yet particularly the gulf cooperation council gcc states have undertaken important steps towards renewable energy adoption which could be greatly facilitated with the use of financial support mechanisms this paper analyzes the feasibility of feed in tariffs and renewable energy auctions adoption in gcc based on an extensive meta analysis of the literature on these two mechanisms in both developed and developing countries the paper identifies a set of conditions necessary for success and evaluates the presence of favorable these conditions in the gcc context our findings reveal that while conditions that would ensure political feasibility are largely absent for both types of mechanisms auctions could be a more successful strategy at the moment

flexible labor compensation risk sharing and company leverage abstract in a traditional wage system the union and the firm bargain ex ante over a compensation level that does not depend on the state of the world under this regime both the wage and the interest earned by debt holders represent predetermined fixed claims on the value of the firm on the other hand in a profit sharing system the union and the firm bargain ex ante over a compensation schedule that does depend on the state of the world in this case the flexible compensation earned by workers becomes a residual claim on the value of the firm similar to the dividend earned by stock holders the implications of this correspondence between compensation structure and financial structure are explored the estimation of a model for the issuance of new long term debt supports the hypothesis of interdependence between financial and compensation decisions

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

competitive auction mechanisms for the promotion renewable energy technologies the case of the 50 mw photovoltaics projects in cyprus abstract there are a range of policy frameworks and support mechanisms to promote the penetration of renewable energy technologies into the energy mix assembled by the governments and regulatory bodies around the world the three dominant and most common support schemes that have also been implemented within the eu and proven successful in the past include the competitive auctions the feed in tariff scheme fit and tradable green certificates tgcs this study reviews the use of the competitive auction mechanism for the promotion of power generation from renewable energy technologies the process of the specific policy instrument as well as its pros and cons are introduced successful and failed case studies from countries that have already incorporated this mechanism into their renewable energy technologies development policies are also presented among these cases is the cyprus auction procurement for the licensing of 50 mw of photovoltaic power plants conducted in january 2013 which is thoroughly elaborated in this paper the timeline of the bids is presented and the auction winner strategy is tracked and examined a discussion is also presented on the feasibility of the awarded projects eventually the entire auction procurement procedure is evaluated to expose the defects of the mechanism and to offer some recommendations for the viability of the process

solar pv where the sun doesn t shine estimating the economic impacts of support schemes for residential pv with detailed net demand profiling abstract countries with low irradiation and solar pv adoption rates are increasingly considering policy support for solar pv although consumer electricity demand and solar generation profiles are often mismatched this paper presents a methodology for policymakers in such conditions to examine more precisely the financial performance of residential solar pv from the consumer perspective as part of an ex ante policy assessment we model a range of prospective policy scenarios and compare policy mechanisms that compensate homeowners for generation those that reduce their upfront costs and those that assist with financing using ireland as a case study the results confirm the intuitive notion that more generous financial remuneration schemes provide quicker payback however we observe that in low irradiance regions there is little difference between upfront grants and feed in tariffs to accelerate payback timeframes we also show the importance of retail tariff structure in consumer payback for solar pv systems with one part tariffs generating shorter paybacks than two part tariff structures although the latter is more likely to secure revenue for electricity infrastructure investment drawing from this analysis the paper proposes some options for the design of policy supports and tariff structures to deliver a sustainable residential renewable electricity system in low irradiance regions

feed in tariff mechanisms for large scale wind power in china abstract in recent years with the large scale and centralized development of the wind power industry in china wind power curtailment has become increasingly serious in order to promote wind power consumption in china this paper designs four kinds of feed in tariff fit mechanisms a double track fit mechanism based on a ratio a time of use benchmarking tariff mechanism a net back pricing mechanism based on the inter provincial wind power consumption market and an fit mechanism based on negotiation then we establish a benefit distribution model to analyze the wind power stakeholders benefits finally based on the four kinds of fit mechanisms and the benefit distribution model we propose the best fit mechanisms for the various electricity market circumstances in china in order to provide a reference to formulate wind fit to promote the consumption of wind power and to advance the sustainable development of renewable energy in developing countries

the age of electricity the age of electricity is coming driven by rapid technological change on the demand side the digitalization of many processes is leading to technologies that require electricity rather than liquid or solid fuels on the supply side renewable energy technologies provide electricity directly at falling cost electrification directly and indirectly e g using electricity to produce hydrogen fuel can aid the decarbonization of the economy strong climate policy would accelerate electrification the big question is when not if and the transition is not occurring anywhere near fast enough to meet the paris climate goals the immediate impact of the coming age of electricity is the transformation of electricity markets which need to adapt to near zero marginal costs and intermittency in the longer term the impact on fossil fuels will be radical fossil fuel prices will fall with demand and the oil and gas majors will either completely transform themselves or will harvest profits and exit

promotion of market access for renewable energy in the nordic power markets this study investigates how renewable targets for the nordic power market might be achieved at the lowest costs the instruments investigated are fixed feed in tariff economically sound premium based feed in tariff and shadow prices for co2 emissions we utilize a real time price based simulation model in the analysis we show that even with strong assumptions regarding the emission permit price the targeted level of wind power is not reached without feed in tariffs emission trading produces the lowest total emissions but with the highest total costs from the studied instruments the most cost efficient way to reach the targets for wind energy market shares is the premium based feed in tariff this tariff is also the most cost efficient way to reduce co2 emissions

the effect of feed in tariffs on the production cost and the landscape externalities of wind power generation in west saxony germany although wind power is currently the most efficient source of renewable energy the cost of wind electricity still exceeds the market price subsidies in the form of feed in tariffs fit have been introduced in many countries to support the expansion of wind power these tariffs are highly debated proponents say they are necessary to pave the way for decarbonising energy production opponents argue they prevent a welfare optimal energy supply thus in a case study we try to shed light on the welfare economic aspect of fit by combining spatial modelling and economic valuation of landscape externalities of wind turbines we show for the planning region west saxony germany that setting fit in a welfare optimal manner is a challenging task if set too high the production costs are overly increased lowering social welfare if set too low energy production targets may not be reached and or external costs are overly increased again lowering social welfare taking a closer look at the tariffs offered by the german renewable sources energy act we find for west saxony that the tariffs quite well meet economic welfare considerations one should note however that this finding might apply only to the present data set

regional net impacts and social distribution effects of promoting renewable energies in germany this paper concerns the net effects of promoting renewable energies on value added and disposable income in germany as well as their distribution among regions and income brackets since its entry into force the german renewable energy sources act eeg has stimulated tremendous investments in renewable energy capacities by guaranteeing investors a fixed price per kwh as well as a preferred feed into the grid over electricity from conventional sources the policy measures are financed by a surcharge on electricity prices in recent years a controversy has arisen about potentially negative regional and social distribution effects in this paper multiregional price and quantity input output models with endogenous heterogeneous households are used to trace the indirect impacts of the eeg on value added and disposable income through the complex network of regional value chains our findings suggest that the generation of electricity from renewable sources itself leads to small positive impacts on industries but leads to a significant drain on household income and has regressive distributive effects however investment in new capacities may possibly transform these negative impacts into a positive direction for the majority of households

design of an economically efficient feed in tariff structure for renewable energy development abstract evidence suggests albeit tentatively that feed in tariffs fits are more effective than alternative support schemes in promoting renewable energy technologies rets fits provide long term financial stability for investors in rets which at the prevailing market price of electricity are not currently cost efficient enough to compete with traditional fossil fuel technologies on the other hand if not properly designed fits can be economically inefficient as is widely regarded to have been the case under the public utility regulatory policies act of 1978 purpa under purpa too high a guaranteed price led to the creation of so called purpa machines poorly performing generating units that could survive financially only because of heavy subsidies that came at the expense of retail customers similarly because of their adverse impacts on retail electricity rates german fits have been subject to increasing political pressure from utilities and customers in this paper we propose an innovative two part fit consisting of both a capacity payment and a market based energy payment which can be used to meet the renewables policy goals of regulators our two part tariff design draws on the strengths of traditional fits relies on market mechanisms is easy to implement and avoids the problems caused by distorting wholesale energy markets through above market energy payments the approach is modeled on forward capacity market designs that have been recently implemented by several regional transmission organizations in the usa to address needs for new generating capacity to ensure system reliability

envisaging feed in tariffs for solar photovoltaic electricity european lessons for canada abstract while it is widely agreed that support schemes need to be put in place to promote the use of renewable electricity there is less consensus as to what are the best kinds of strategies to use what is attracting increasing attention in canada is a system of renewable portfolio standards in this all power suppliers are under an obligation to ensure that a certain percentage of the electricity they generate is from renewable resources they can either generate that electricity themselves or purchase green certificates from those who have used renewables to generate electricity recent experience from europe however suggests that a whole hearted commitment to this single strategy could be premature and potentially damaging for the development of all kinds of renewable electricity in canada solar photovoltaics included on the other side of the atlantic ocean the use of so called feed in tariffs that is an obligation for utilities to purchase at a set price the electricity generated by any renewable energy resource is widely credited with accelerating the development of renewable electricity in many countries the purpose of this article is to reflect upon this european experience with feed in tariffs to stimulate discussions regarding what promise they might hold for the development of solar photovoltaic electricity in canada the article is divided into three main sections in the first section policies to promote renewable electricity presently in place in different parts of canada are reviewed attention is then focused more specifically in the second section of this article upon feed in tariffs after defining and describing this alternative system experiences in the countries of the european union are reviewed the main strengths and weaknesses of feed in tariffs in the european experience are also examined the focus then moves back to canada in the third section of the article in this a system of feed in tariffs is proposed for the province of ontario in order to provide just one example of the kind of support that could be forthcoming

an overview of incentive policies for the expansion of renewable energy generation in electricity power systems and the brazilian experience abstract energy production from renewable sources is already a reality in many countries and with that different strategies for incentivizing investments in renewable energy generation have been proposed and used over the years in this study long term policies that have been applied in several countries such as feed in tariffs shares with commercialization of certificates auctions and net metering are overviewed and discussed the main advantages and disadvantages of these incentive strategies are emphasized focusing on applications some of these strategies that have already been applied in brazil are analyzed in greater depth emphasizing the potentialities and fragilities of these mechanisms observed within the country even though it is a country that stands out in relation to other latin american countries regarding electricity generation from non hydro renewable sources brazil still faces barriers that prevent a utilization compatible with its potential moreover the trend for renewable sources such as wind and solar power is to represent an energy capacity reserve to cover hydrological risks and also to contribute to a distributed generation spread through electricity distribution networks

feed in tariffs combined with capital subsidies for promoting the adoption of residential photovoltaic systems abstract both feed in tariffs fits and capital subsidies have been widely employed to promote the adoption of renewable energy technologies this study sheds light on the combined use of fits and capital subsidies the purpose of the study is to clarify their optimal combinations in order to encourage households to adopt photovoltaic pv systems the study develops a microeconomic model embodying the idea of two part tariffs the most important findings concern the combination that maximizes social welfare if fits are applied to the total pv electricity generated they should be set at the avoided cost per unit of pv electricity and capital subsidies should be used to control the number of adopters whereas if fits are applied to only surplus pv electricity the previous principle is distorted however a numerical example suggests that the distortion has little effect on the maximized social welfare and thus it makes little difference whether fits are applied to all pv electricity or just the surplus pv electricity the findings may also be applied to the adoption of wind power generation systems and to adoption by businesses

boosting solar investment with limited subsidies rent management and policy learning in india in order to avoid irreversible damage to global ecosystems new green technologies are needed some of which are nowhere near commercial maturity in these cases governments may create temporary rents to make investments artificially attractive but the creation of such rents involves risks of faulty allocation and political capture this article first highlights the importance of managing rents effectively in promoting green technologies it then shows how india s national solar mission has been remarkably effective in triggering solar investments and managing the necessary subsidies e g through a process of competitive reverse bidding for tariffs policy design and implementation also reflect considerable experimentation and learning some risks remain especially regarding the enforceability of renewable energy quotas at the level of indian states

what do we know about the study of distributed generation policies and regulations in the americas a systematic review of literature abstract policy makers are increasingly in search for evidence based solutions for meeting contemporary challenges of energy services that are both low carbon and sustainable one of the emerging trends are policies and regulations that incent distributed electricity generation dg the question that this article addresses is what is the current state of the study of these policies or regulations in the americas the focus on the americas was chosen because the article is part of a larger research project that explores regulations for dg in brazil and canada this article uses a non traditional means for synthesizing academic work systematic literature review to explore the current state of peer reviewed publications on the subject it is a means of transparently locating evaluating and synthesizing information to avoid bias in data collection in total 87 articles were included in the review climate change is the main driving force for dg as identified in the articles job creation or the green economy was cited as a motivating factor more strongly in north america while in the southern countries the issue of diversifying the energy mix and avoiding infrastructure costs was more pronounced many articles dealt with the issue of mechanisms for incenting dg and over half of these focused on aspects of feed in tariffs incentive mechanisms vary depending on policy goals of the jurisdictions with renewable portfolio standards being more popular in the u s the review showed that there is little emphasis on the social impacts and benefits of the regulations or policies and that specific urban challenges and local governance is not widely investigated pointing to a need for future study in these areas

integration of renewable energy sources in southeast europe a review of incentive mechanisms and feasibility of investments abstract incentivizing development and deployment of renewable energy sources res but also other low carbon technologies lct has been a successful way of promoting new technologies by creating a feasible investment case and making them competitive with traditional energy sources although different incentive mechanisms exist feed in tariffs have shown to be the best model for accelerating lct development guaranteeing producers preferential prices for the produced electricity over a period of time and enabling them access to the power network to sell inject produced electricity due to these benefits feed in tariff models are the most common model for stimulating res integration in southeast europe the paper reviews the current state of preferential tariffs for res in countries of southeast europe while some countries already have significant installed res capacity others are still in the planning stage the review shows that the amount of installed capacity of a specific technology has a strong impact on the support for the future projects for same technology this comprehensive review of legislative development supporting res as well as technologies preferred in different countries of the region is supported with feasibility assessment of investing in res using the example of two different technology projects wind and photovoltaic analysing the impact of the current tariffs on the return on investment for each country of the region

assessing the strength and effectiveness of renewable electricity feed in tariffs in european union countries in the last two decades feed in tariffs fit have emerged as one of the most popular policies for supporting renewable electricity res e generation a few studies have assessed the effectiveness of res e policies but most ignore policy design features and market characteristics e g electricity price and production cost that influence policy strength we employ 1992 2008 panel data to conduct the first econometric analysis of the effectiveness of fit policies in promoting solar photovoltaic pv and onshore wind power development in 26 european union countries we develop a new indicator for fit strength that captures variability in tariff size contract duration digression rate and electricity price and production cost to estimate the resulting return on investment we regress this indicator on added res e capacity using a fixed effects specification and find that fit policies have driven solar pv development in the eu however this effect is overstated without controlling for country characteristics and is concealed without accounting for policy design we do not find robust evidence that fit policies have driven wind power development overall we show that the interaction of policy design electricity price and electricity production cost is a more important determinant of res e development than policy enactment alone

social equity issues in the distribution of feed in tariff policy benefits a cross sectional analysis from england and wales using spatial census and policy data abstract the feed in tariff has become a popular policy instrument globally for deploying clean energy often involving substantial public spending commitments yet relatively little attention has been paid to how payments made under this policy type get distributed across socioeconomic groups this paper links information on individual domestic photovoltaic pv installations registered under the feed in tariff for england and wales to spatially organised census data this makes it possible to observe which socioeconomic groups are benefitting most and least under the policy comparing the observed benefit distribution to a counterfactual distribution of perfect equality a moderate to high level of inequality is found cross sectional regressions suggest that settlement density home ownership status physical dwelling type local information spillovers and household social class shaped this outcome greater sensitivity to these factors in policy design could improve distributional outcomes under feed in tariff policies in england and wales and beyond

an economic analysis for the design of ipp contracts for grid connected renewable energy projects abstract in this paper we undertake an integrated financial economic stakeholder analysis of a grid connected onshore wind project that is owned and operated by an independent power producer ipp in santiago island cape verde this ipp project has received considerable positive publicity and has won many awards cape verde has a very good wind resource but it suffers from high transportation costs for petroleum fuels due to its location hence it would appear to be an ideal site for an ipp investment in a wind farm this analysis is conducted from the perspectives of the electric utility the country s economy the government and the private sector investor the key question is whether the design of the power purchase agreement ppa can simultaneously yield a high enough cash flow for the project to be bankable while at the same time yielding a positive net financial and economic present value to the electric utility and the country respectively the analysis shows that a negotiated ppa results in a negative outcome for the economy of cape verde in almost all circumstances in contrast the owners of the ipp are guaranteed under all circumstances a very substantial return on their investment

the design of renewable support schemes and co2 emissions in china abstract the renewable energy targets put forward by the chinese government need comprehensive incentive schemes this paper uses a multi regional cge model to evaluate two types of renewable support schemes a subsidy scheme like a feed in tariff fit with a direct price impact for final consumers and a subsidy scheme without any price impact we assess the co 2 consequences of both approaches as well as their impact on economic activity in terms of gdp industrial structure electricity generation structure and regional final demand elasticities of electricity we find that a support scheme with price impact is much more effective in reducing co 2 emissions while the difference in gdp between the two policies is small we estimate that the price implications of the support scheme allow for an additional emissions reduction of 113 mt co 2 or 0 07 of total emissions in china during 2020 2035 the support scheme with a price impact does not lead to a negative impact on the chinese economy although there are significant differences among regions in addition while the whole country faces an approximately unitary electricity elasticity demand we find significant differences in electricity demand elasticities among chinese regions

economic welfare and environmental impact of feed in tariff policy a case study in iran following a particular attention given to environmental issues over the last few decades establishing proper developmental policies to increase electricity production from renewable energy re has not only been an important issue but also a challenge for many countries feed in tariff fit policy is one of the tools that is being used to facilitate the development of re this research evaluated the economic welfare and environmental impact of this policy on iran s economy therefore after developing an economic energy environmental e3 type of hybrid general equilibrium model the effect of fit policy was examined under different scenarios in order to find an optimal condition in which 10 of electrical energy could be produced from renewable resources the comparison between the results showed that the application of subsidies to re and the way the government finances these subsidies can affect the results of fit policy meanwhile regardless of the role considered for the impact of environmental factors our policies under the scenario of technology neutral is the most efficient as it has less impact on the decline of gdp of different sectors and also has less financial cost for government

sustainability guided promotion of renewable electricity generation in recent years the threat of global climate change high fuel import dependence and rapidly rising electricity demand levels have intensified the quest for more sustainable energy systems this in turn has increased the need for policy makers to promote electricity generation from renewable energy sources guaranteed prices coupled with a buy back obligation for electricity fed into the grid is a popular renewables promotion instrument especially in europe more recently driven mainly by electricity market liberalisation efforts quota targets for the share of renewables in combination with tradable green certificates tgc have received considerable attention tgc offer a greater theoretical potential for economic efficiency gains due to price competition and the greater flexibility assigned to the obliged parties while guaranteed prices and tgc schemes support the operation of renewable energy technology systems bidding schemes for renewable energy generation capacity are used to raise economic efficiency on the plant construction side all of these policy instruments suffer from the shortcoming that they do not explicitly account for the often widely varying environmental social and economic impacts of the technologies concerned in this paper we propose a methodology for the design of renewable energy policy instruments that is based on integrated assessment in particular we argue that using participatory multicriteria evaluation as part of the design of renewable energy promotion policies would make it possible 1 to differentiate the level of promotion in a systematic and transparent manner according to their socio ecological economic impact and 2 to explicitly account for the preferences of stakeholders a further problem of existing tgc and bidding schemes is that diversity of supply could be severely diminished if few low cost technologies were allowed to dominate the renewable energy market to ensure a certain diversity of technologies our scheme suggests the use of different technology bands for technologies that are relatively homogeneous with respect to their maturity

a two part feed in tariff for intermittent electricity generation abstract as electricity generation from intermittent energy sources wind sun tides is gaining momentum it becomes increasingly important to price these electricity sources efficiently conventional flat feed in tariffs ignore the heterogeneity of these sources taking into account the degree of substitutability or complementarity of these sources with respect to each other and with respect to stochastic demand variations this paper derives optimal pricing instruments composed of a feed in tariff fit and a capacity augmentation tariff cat an empirical analysis looks at wind and solar farms operating in ontario in order to determine the optimal use of fit cat pricing the magnitude of optimal price differentiation turns out to be economically significant furthermore the emergence of grid scale electricity storage underscores the need to price energy and capacity separately

the large scale solar feed in tariff reverse auction in the australian capital territory australia abstract feed in tariffs fits offer renewable energy developers significant investor certainty but sometimes at the cost of being misaligned with generation costs reverse fit auctions where the fit rights for a predetermined capacity are auctioned can overcome this problem but can be plagued by non delivery risks particularly of competitively priced proposals in 2012 and 2013 the australian capital territory act government in australia conducted a fit reverse auction for 40 mw of large scale solar generating capacity the first such auction undertaken in the country the auction was highly competitive in relation to price and demonstrating low delivery risks proposal capital costs particularly engineering procurement and construction costs as well as internal rates of return were lower than expected the auction process revealed limited land availability for large scale solar developments in the act as well as a significant perceived sovereign risk issue the auction process was designed to mitigate non delivery risk by requiring proposals to be pre qualified on the basis of delivery risk before considering fit pricing the scheme is likely to be used by the act government to support further large scale renewable energy development as part of its greenhouse gas reduction strategy which is underpinned by a 90 per cent by 2020 renewable energy target

determining commercially viable two way and one way contract for difference strike prices and revenue receipts abstract in this article we investigate the role that a contract for difference cfd might play in increasing investment in renewable energy in australia two cfd schemes are investigated two way and one way cfd a financial model is developed that determines commercially viable cfd strike prices account is taken of revenue from wholesale electricity market and renewable energy certificate sales capital and operational costs of the project including distribution of funds to holders of equity and debt are also included findings based on analysis of the solar array located at the university of queensland gatton campus in australia is presented employing a typical meteorological year framework the major finding was that government will prefer a two way cfd scheme and single axis tracking solar pv array technology in contrast project proponents will strongly prefer a one way cfd design

feed in tariff design for domestic scale grid connected pv systems using high resolution household electricity demand data abstract the advent of large samples of smart metering data allows policymakers to design feed in tariffs which are more targeted and efficient this paper presents a methodology which uses these data to design fits for domestic scale grid connected pv systems in ireland a sample of 2551 household electricity demand data collected at 1 2 hourly intervals electricity output from a 2 82 kwp pv system over the same time interval as well as pv system costs and electricity tariffs were used to determine the required fit to make it worthwhile for the households to invest in the pv system the methodology shows that it is possible to design single multiple and continuous fits continuous fits are the most efficient and result in no overcompensation to the housholder while single and multiple fits are less efficient since they result in different levels of overcompensation in the pv case study considered it was shown that the use of three fits 0 3170 0 3315 and 0 3475 kw h resulted in a 59 6 reduction in overcompensation compared to a single fit of 0 3475 kw h assuming immediate and complete uptake of the technology this would result in npv savings of over 597 m to the irish government over a 25 year lifetime

an overview of implemented renewable energy policy of pakistan abstract after initiation of renewable energy policy in 2006 yet it could not be executed the green path for sustainable energy development in pakistan currently the share of non hydro big hydro projects renewables is less than 4 less than 900 mw of total installed electricity capacity against the medium term plan of having minimum capacity of 9700 mw in 2030 with several strategies and goals established in place to support the development of renewables however it is not well organized and also ill managed to find the effective renewable energy mix for the country according to targets this study aims to analyze that whether targets of renewable energy technology rets deployment will be met under the current regime a cross country analysis of renewable energy status reveals the workable instruments to increase the growth of rets amongst developed and developing nations it is clearly evident that without supplementary and policy instruments these ambitious targets cannot be achieved the strong political and financial commitments are necessary to accomplish the green pathway as governments are more tilted towards thermal power generation to overcome the huge electricity demand supply gap

the solar photovoltaic feed in tariff scheme in new south wales australia solar photovoltaic pv electricity systems are part of australia s energy supply matrix in the case of new south wales nsw the state government has had to deal with a complex policy problem in order to play its role in the federal small scale renewable energy scheme the nsw government initiated the 7 year solar bonus scheme in 2010 however in attempting to maximise community investment in small scale solar pv systems it relied on faulty financial modelling that applied a generous feed in tariff fit and underestimated the level of investor participation and installed capacity consequently the scheme has resulted in very high public costs that will require policy changes that bring investors and energy retailers into conflict and unpopular electricity retail price adjustments this paper uses a structured case and stakeholder analysis to critically analyse the fit policy while also highlighting important lessons for policymakers engaging in fit design

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

impact of cheaper oil on economic system and climate change a swot analysis abstract the drop in crude oil price by nearly half since june 2014 has created new opportunities as well as challenges this study employs the swot method to analyze the impact of cheaper oil on the global economic system and carbon emissions exploring the climatic opportunities and identifying the challenges of lower oil prices in addition it contends that falling oil prices boost economic growth but produce more carbon pollutants thereby accelerating global warming however cheaper oil has provided a window of opportunity to remove fossil fuel subsidies a major development that years of climate shaming has failed to achieve furthermore we argue that social factors are a critical often overlooked threat for the removal of fossil fuel subsidies with declining oil prices exerting downward pressure on gas and coal the removal of subsidies and carbon tax can be introduced without raising the energy prices four policy recommendations are proposed for the removal of fossil fuel subsidies to limit global warming as well as to meet the challenge and opportunity of cheaper oil removal of fossil fuel subsidies should be quickly implemented because this window of opportunity of cheaper oil will not last forever

long term effects of feed in tariffs and carbon taxes on distribution systems in deregulated electricity sector climates such as in ontario the production of clean or renewable energy by small power producers through distributed generation dg is encouraged this paper examines the policies that can be used to encourage dg investment and incorporates them into a mathematical model this model is then used to create scenarios for examining the economic and environmental supply side effects of policies to a distribution system over a ten year period the policies analyzed include a combination of feed in tariffs co2 tax and cap and trade schemes the results are discussed in the context of the ontario market and its standard offer program implemented on a 32 bus radial distribution system

is green energy expensive empirical evidence from the spanish electricity market abstract renewable energy promotion and its cost are at the heart of the energy policy debate in many countries the question from an economic perspective is how expensive the promotion of renewable sources through price based incentive schemes is this paper addresses this issue empirically we analyze the spanish electricity market during the period 2008 2012 where renewable energy production rose by 57 to determine how expensive it was we first measure the savings due to the spot price reduction driven by the merit order effect and second we compute the amount paid as incentives to green energy by the electricity system the difference between the two is the net cost of green energy to the electricity markets we present aggregate results for renewable sources as a whole as well as individual results for each technology we show that at the initial stages when renewable capacity was low green energy promotion paid for itself 2008 2009 however from 2010 on when renewable production reached a relatively high level it started to impose a positive net cost on the system finally we found substantial differences among technologies wind energy implied the lowest net cost while solar photovoltaic was the most expensive

the potentials of a reverse auction in allocating subsidies for cost effective roof top photovoltaic system deployment abstract photovoltaic pv has developed to one of the most promising technologies for renewable electricity generation the austrian government currently provides subsidies for roof top pv systems through a constant administratively determined feed in tariff or an investment co funding in both subsidy schemes applications are approved on a first come first served basis there are concerns about i the selection of suitable roofs for pv systems and ii allocating subsidies among applicants to deploy roof top pv systems cost effectively thus we analyze the potentials of a simple discriminative first price reverse auction application scheme applicants define individually the required level of subsidy and those with the lowest request for subsidies are selected in an ex post analysis we evaluate the potentials of such a scheme in increasing power output and saving public spending for the federal state of vorarlberg in austria results indicate a potential increase of cumulated produced electricity between 15 and 18 in comparison to the current policy in addition a reverse auction based system would lead to savings of public spending per kwh between 20 and 41

the main support mechanisms to finance renewable energy development considering that the major part of greenhouse gases is carbon dioxide there is a global concern aimed at reducing carbon emissions additionally major consumer countries are looking for alternati

optimal design of feed in tariffs to stimulate renewable energy investments under regulatory uncertainty a real options analysis feed in tariffs fits are widely used as policy instruments to promote investments in renewable energy sources res while fits are often regarded as the most effective res support scheme regulators around the world continuously review their fit schemes in the light of budget constraints and evolving policy goals we assess the impact of adjustments to fit schemes by quantifying the relationship between fit levels i e the guaranteed amount paid per quantity of electricity produced and the propensity to invest in res through a regime switching model we quantify the impact of regulatory uncertainty induced by regulators considering moves from a fit scheme to a more market oriented regulatory regime our focus is on market independent fixed fits the dominant scheme in europe receiving increasing attention globally we find that res investment projects under market independent fixed fit schemes become now or never decisions and derive fit thresholds required to induce investment we show that uncertainty regarding future regulatory regimes delays or even reduces investment activity for fit levels near electricity market prices and high probabilities of an imminent regime switch

risk based assessment of the cost efficiency and the effectivity of renewable energy support schemes certificate markets versus feed in tariffs the introduction of renewable energy sources in the electricity generation mix has the potential to reduce power sector s emissions and countries dependence on imported oil climate change concerns and highly volatile oil prices have attracted governments interest and support to sustain investments in renewable energy capacity and different support policies have been implemented in many countries around the world this paper analyzes the effects of investors risk aversion on the performance of support schemes the analysis compares two policy options a feed in tariff mechanism with a certificate market system results show that while a tariff mechanism could obtain better results than a certificate market its performance is strictly dependent on regulator choices a certificate market instead permits to obtain the desired level of renewable energy market share with good cost efficiency as long as investors risk aversion is moderate moreover discounting future cash flows with higher social discount rates further benefits a certificate system making it preferable to feed in tariffs

examining the financial performance of micro generation wind projects and the subsidy effect of feed in tariffs for urban locations in the united kingdom abstract this paper seeks to evaluate the effect of the upcoming 2010 uk feed in tariff uk fit on decentralised small wind energy installations at the household and building level in urban locations it is projected that the uk fit will stimulate an unprecedented surge in building mounted turbine installation the tariff amount must stimulate incentive but mitigate the likelihood of distortions in the competitive electricity market to analyse these issues measured energy output from sites in the warwick wind trials project wwtp is converted into revenue in a net present value npv framework for assessing commercial purchases of small wind systems variances in project variables are examined through npv simulations using monte carlo analysis to capture permutations of small wind project performance in the uk with and without the uk fit our research concludes that the proposed tariff amount of 30 5 p kwh will not significantly boost the economic attractiveness of mildly selective wwtp based sites in the uk furthermore the fixed tariff rate kwh generated could cause inefficiencies applied across uneven wind resource distribution the results of this study suggest further examination of policy related to micro generation in particular decentralised small wind projects

economic analysis of pv systems on buildings in sicilian farms abstract the photovoltaic sector in italy in recent years has experienced a rapid growth also in the primary sector thanks to substantial incentives guaranteed by energy policies simultaneous reduction of investment costs and tax benefits in order to better understand the growth of the pv industry in italian primary sector the aim of this paper has been to evaluate the economic convenience of four pv systems on farm buildings located in four different farms of the north western coast of sicily and realized during the second and fourth italian feed in schemes for each feed in scheme it has been considered a pv plant that sells the electricity to the grid and another in which the energy generated is consumed entirely by the farm the results show a clear convenience to the realization of investments both with the current market conditions and at the variation of the feed in tariff or the investment costs

the politics of renewable energy policies the case of feed in tariffs in ontario canada designing and implementing a renewable energy policy involves political decisions and actors yet most research on renewable energy policies comparatively evaluates instruments from an economic or technical perspective this paper presents a case study of ontario s feed in tariff policies between 1997 and 2012 to analyze how the political process affects renewable energy policy design and implementation ontario s policy although initially successful has met with increasing resistance over time the case reveals key political tensions that arise during implementation first high level support for a policy does not necessarily translate into widespread public support particularly for local deployment second the government often struggles under asymmetric information during price setting which may weaken the policy s legitimacy with the public due to higher costs third there is an unacknowledged tension that governments must navigate between policy stability to spur investment and adaptive policymaking to improve policy design fourth when multiple jurisdictions pursue the same policies simultaneously international political conflict over jobs and innovation may occur these implementation tensions result from political choices during policy design and present underappreciated challenges to transforming the electricity system governments need to critically recognize the political dimension of renewable energy policies to secure sustained political support
