美国加州可再生能源配额制及对我国的启示

配额制本质上是一种对可再生能源开发的激励机制,它的实施需要具备一定的前提条件,目前仍处于不断探索和发展阶段。配额制的实质是以最低成本开发可再生能源,它通常需要依托一个绿色证书市场。任何配额制基本上都包含了配额承担主体及合格的发电类型、配额目标的确定及分解、运作机制、成本分摊与惩罚措施等内容。世界上没有任何两个国家或地区的配额制是完全一致的,均是根据本国或本地区的实际情况而制定。加利福尼亚州是美国可再生能源发展较快,也是最早实施配额制的联邦州之一。加州配额制的配额承担主体主要是为终端用户供电的电力企业;运作机制是通过绿色证书来代替物理计量,以证书数量来反映配额承担主体的履约情况;实现配额义务的成本是通过终端销售电价疏导出去的。这些与英国和日本的配额制相同,而差异性体现在配额目标形式不同、指标分解原则不同以及对不同类型可再生能源的激励程度不同。我国在可再生能源配额制设计中需要关注与现行可再生能源政策的衔接、地区配额指标的差异化设计、地方政府的责任、可再生能源电量的计量以及保障措施等问题。     

英国可再生能源义务政策最新进展及对我国的启示

从90年代的非化石燃料义务政策到2002年以来的可再生能源义务政策,英国一直致力于通过市场配额机制推动可再生能源发展。但由于政策机制设计复杂,不确定性较大,以及罚金返还导致的市场投机等问题,无法拉动足够投资保障可再生能源快速发展。2011年,结合碳减排目标,英国政府计划推出一揽子电力市场改革方案(EMR),其重点之一是可再生能源义务逐步向差价合约固定电价政策转移。本文通过综述英国可再生能源义务政策演变历程,解析评价可再生能源证书市场运行机制和实施效果,并介绍英国电力市场改革方向,以及对我国的启示。     

论我国可再生能源配额制的法制建构

可再生能源配额制是推动可再生能源发展的有效制度,是实现可再生能源发展目标的量化、强制性以及与之配套的市场化措施。2006年制定的《可再生能源法》及2009年修改的《可再生能源法》已经为可再生能源配额制在我国立足生根营造制度环境。我国先后草拟可再生能源配额制的若干文件,但是迟迟未能完全落实。我国应当全面设计可再生能源配额义务的承担主体、配额分配机制、配额考核、监管以及基于配额制的绿色证书交易制度,从而保障我国可再生能源的可持续发展。     

可再生能源配额制的思考

文章分析了世界可再生能源配额制的几种模式，总结了其成功的经验，结合我国的可再生能源资源情况及现状，提出了中国推行可再生能源配额制的一些思考和建议。     

可再生能源配额制出炉

近日,由国家能源局起草的《可再生能源电力配额考核办法（试行）》（下称《考核办法》）,已经由国家发改委主任办公会讨论并原则通过,目前正在征求各方建议,方案再次修订后将上报国务院审定。《考核办法》的出台标志着“最难产”的可再生能源配额制即将出炉。这也是近一段时间内新能源行业最大的一次利好。     

可再生能源配额制之辩

由于电力管理体制不同,中外配额制的制度设计存在很大差异,我国需要怎样的可再生能源配额制？     

可再生能源配额制对优化我国电源结构的影响分析

基于可再生能源电力将由强制上网制转为配额制这一背景,针对当前电源结构不合理以及可再生能源发展障碍等问题,建立了引入配额制后发电厂商利润最大化模型,并结合中国电力企业联合会的最新数据进行实证分析。结论表明:可再生能源电力从强制上网制转变为配额制后,配额比例的提高会使煤电的边际成本上升,而绿电的边际成本下降,继而影响发电量,即煤电的电量下降,绿电的电量上升。由此表明,引入可再生能源配额制可有效地优化中国的电源结构,改善过度依赖煤电的现状。     

可再生能源配额制(RPS)在中国应用探讨

我国政府近些年来一直积极探索以强制性手段保障可再生能源发展的有效机制。2003年可再生能源立法开始列入议程,这是我国可再生能源发展史上的一项重要举措。为可再生能源电力入网提供强制性保障机制是此次立法工作中初步设想的一项内容,引入可再生能源配额制(RPS)成为可供考虑的选择方案之一。如果引入,对该政策进行细致周密的设计和保证有效实施是至关重要的。文章重点探讨了RPS政策设计和管理中应注意的几个主要问题,包括确立适用范围和责任主体、制定可再生能源目标、确定有效的可再生能源种类、建立绿色证书制度、制定处罚措施等。期望本文能为我国建立可再生能源法律和政策体系提供相关信息。     

The environmental and cost implications of solar energy preferences in Renewable Portfolio Standards

Many state-level Renewable Portfolio Standards (RPS) include preferences for solar generation, with goals of increasing the generation diversity, reducing solar costs, and encouraging local solar industries. Depending on their policy design, these preferences can impact the RPS program costs and emissions reduction. This study evaluates the impact of these policies on costs and emissions, coupling an economic dispatch model with optimized renewable site selection. Three policy designs of an increased RPS in Michigan are investigated: (1) 20% Solar Carve-Out, (2) 5% Distributed Generation Solar Carve-Out, and (3) 3× Solar Multiplier. The 20% Solar Carve-Out scenario was found to increase RPS costs 28%, while the 5% Distributed Generation Solar Carve-Out increased costs by 34%. Both of these solar preferences had minimal impact on total emissions. The 3× Solar Multiplier decreases total RPS program costs by 39%, but adds less than half of the total renewable generation of the other cases, significantly increasing emissions of CO₂, NO_x, and SO₂ relative to an RPS without the solar credit multiplier. Sensitivity analysis of the installed cost of solar and the natural gas price finds small changes in the results of the Carve-Out cases, with a larger impact on the 3× Solar Multiplier.     

The diverging paths of German and United States policies for renewable energy: Sources of difference

The United States and Germany started out with very similar policies for renewable energy after the energy crisis of the 1970s. By the year 2000 they were on very different policy paths and, as a result, the German renewable energy industry has moved well ahead of that in the United States, both in terms of installed capacity in the country and in terms of creating a highly successful export market. In this paper, we reject some of the conventional explanations for this difference. Instead, these differences arise from the intersection of contingent historical events with the distinctive institutional and social structures that affect policy making in each country. Our analysis of the historical path-dependent dynamics of each country suggests that those who wish to further renewable energy policy in the United States need to take into account these institutional and social factors so that they will better be able to exploit the next set of favorable historical circumstances.     

Lessons for effective renewable electricity policy from Denmark,Germany and the United Kingdom

Renewable electricity development has taken different paths across countries, underpinned by different policy frameworks. Although there has been a convergence to two main mechanisms, the feed-in tariff (FIT) and the renewable portfolio standard (RPS), much debate remains focused on the effectiveness of each for meeting multiple objectives, especially energy security, CO₂ reduction and economic development. Although most countries share these objectives, their choice of policy varies, explained largely by national context. Denmark, Germany and the United Kingdom stand out as lead countries based on their experiences with the FIT and RPS and provide important lessons for other nations. The evidence from these three, as examined in this paper, suggests that policy design and commitment are key factors for success. Denmark and Germany have 10 years of experience with FITs and are world leaders in the field of renewable energy (RE) development. They are closest to meeting their RE targets and have been able to achieve several other objectives, especially industrial development and job creation, and in the case of Germany, CO₂ emission reductions. Although other factors have been important in determining policy choice and implementation in these countries, the particular design features of the FIT allow it to address the needs of the sector.     

Renewable energy policy and electricity market reforms in China

The article examines the potential effectiveness of the renewable energy policy in China and its regulatory Law framework. It frames the option of renewable energy technology within the background of the long-lasting electricity problems that China has faced including serious supply shortages, reliance on coal, and severe environmental contamination. Its dual administrative and ownership system based on state and privately owned industry is discussed together with the market reform measures adopted in the sector. Current renewable energy policy is analysed, and the scope of the 2005 Renewable Energy Promotion Law is investigated. This is conducted within the context of the electricity sector reform that China adopted, and its effects upon the prospects of encouraging as well as expanding the development of renewable energy. This study draws upon primary information collected from interviews with stakeholders on the policy adequacy, and identifies three main types of shortcomings that have interfered with a more successful expansion of renewable energy in China.     

Bio-energy in the Baltic States: Current policy and future development

The rapid economic growth in the Baltic States requires significant alterations in their energy sectors. This paper describes current status and specific features of the energy systems in the Baltic States, and in particular discusses the role of the renewable energy sources in the primary energy supply and energy transformation sector of these countries. The structure of the energy sectors inherited from the Former Soviet Union and constructed through several decades was inappropriate in terms of size of these countries and their access to primary energy. Based on common principles changes in the primary energy supply during the period 1990–2003 in each country are analysed. This paper presents analysis of the main driving forces for future usage of bio-energy, such as sound general energy policy in the Baltic States, favourable legislative framework, implementation of the EU Directives and corresponding National Programs. The paper focuses on comparison of existing potential for energy production from feasible renewable energy sources, trends of bio-energy production and the role of renewable energy sources for the future energy needs in the Baltic States. Due to existence of some limiting factors additional energy policy measures encouraging future development of bio-energy production in the region are necessary.

Renewable electricity in Sweden: an analysis of policy and regulations

This study aims to analyse the developments in renewable energy policy making in Sweden. It assesses the energy policy context, changes in the choice of policy instruments, and provides explanations behind policy successes and failures. Swedish renewable energy policy has been developing in a context of uncertainty around nuclear issues. While there has been made a political decision to replace nuclear power with renewables, there is a lack of consensus about the pace of phasing out nuclear power due to perceived negative impacts on industrial competitiveness. Such uncertainty had an effect in the formulation of renewable energy policy. Biomass and wind power are the main options for renewable electricity production. Throughout 1990s, the combined effect of different policy instruments has stimulated the growth of these two renewable sources. Yet, both biomass and wind power are still a minor contributor in the total electricity generation. Lack of strong government commitment due to uncertainty around nuclear issues is a crucial factor. Short-term subsidies have been preferred rather than open-ended subsidy mechanisms, causing intervals without subsidies and interruption to development. Other factors are such as lack of incentives from the major electricity companies and administrative obstacles. The taxation system has been successful in fostering an expansion of biomass for heating but hindered a similar development in the electricity sector. The quota system adopted in 2003 is expected to create high demand on biomass but does not favour wind power. The renewable energy aims are unlikely to be changed. Yet, the future development of renewable energy policies especially for high-cost technologies will again depend strongly on nuclear policies, which are still unstable and might affect the pace of renewable energy development.
