Tradable white certificate schemes: fundamental concepts

A number of European countries have introduced market-based instruments to encourage investment in energy efficiency improvement and achieve national energy savings targets. Some of these schemes are based on quantified energy savings obligations imposed on energy distributors or suppliers, coupled with a certification of the energy savings (via white certificates), and a possibility to trade certificates. The paper describes the concept and the main elements of a tradable white certificate scheme, where appropriate giving examples from existing schemes in Europe. It discusses design and operational features that are key to achieve the overall savings targets, such as delineation of the scheme in terms of obliged parties, eligible projects and technologies, institutional structure, and processes to support the scheme, such as measurement and verification. Finally, the paper looks at a number of open issues, most importantly the possibility of creating a voluntary market for white certificates via integration into the carbon market.

White Certificates for energy efficiency improvement with energy taxes: A theoretical economic model

In this paper we analyze interactions of two energy policy instruments, namely a White Certificates (WhC) scheme as an innovative policy instrument for energy efficiency improvement and energy taxation. These policy instruments differ in terms of objectives and final impacts on the price of electricity. We examine the effect of these policy instruments in the electricity sector, focusing on electricity producers and suppliers in a competitive market. Using microeconomic theory, we identify synergies between market players and demonstrate the total effect on the electricity price when suppliers internalize the behaviour of producers in their decisions. This model refers to an ideal market situation of full liberalization. The cases we examine consist of electricity producers with and without a carbon tax, electricity suppliers with and without an electricity tax, and with WhC obligations. Furthermore, we present a parallel implementation of WhC for electricity suppliers with carbon tax on electricity producers and an electricity tax with WhC obligations to electricity suppliers. We demonstrate differences in optimization behaviour of producers and suppliers. Based on a couple of cases of WhC with carbon and electricity taxes, various positive and negative effects of both schemes in terms of target achievement and efficiency are present, which can lead to an added value of such schemes in the policy mix, although uncertainties of outcomes are quite high. A basic finding is that in a merit order several parameters can increase final electricity price after the implementation of different policies: demand for electricity and electricity supply cost at a large scale and then follow the level of level of obligation for energy saving, level of penalty, and price of WhC (representing the marginal costs of energy saving projects). The impact magnitude of parameters depends on the values chosen and on the initial position of suppliers (i.e. if their actual behaviour deviates from full compliance with targets).     

An ex-ante evaluation of a White Certificates scheme in The Netherlands: A case study for the household sector

Increased efficiency of energy demand is generally recognized as a very cost-effective strategy to reduce energy requirements and the related environmental impacts (e.g. the greenhouse effect). In order to improve energy efficiency the use of innovative market mechanisms, such as the White Certificates (WhC), has been proposed. The basic idea underlying this policy instrument is that specific energy saving targets are set for energy suppliers or energy distributors. These requirements must be fulfilled in a predefined time frame. The focus of this paper is on the effect on energy efficiency improvement, on the behavior of the end consumers and the market of energy efficiency measures. Furthermore, we study the possible effects of WhC in The Netherlands by means of a theoretical analysis and an empirical bottom-up model. We compare concrete energy efficient technologies in terms of cost-effectiveness and energy efficiency improvement. In combination with existing Dutch policies for energy efficiency improvement in the built environment, the contribution of this innovative scheme could enhance the accomplishment of energy efficiency targets. In this paper, two packages of energy saving measures of a WhC scheme are studied for Dutch households. The costs of these technologies are estimated through the use of different discount rates, which imply overcoming of the market barriers through the use of the WhC. A scheme that includes all available technologies as flexible options appears as a realistic solution and can generate cost effectively up to 180 PJ primary energy savings and 4550 M€ cumulative net savings in the year 2020, at a discount rate of 5%, under the precondition that the policy and administrative costs can be kept low.     

Towards cooperative policy approaches in China—Drivers for voluntary agreements on industrial energy efficiency in Nanjing

Energy efficiency is a national priority for China as rapid energy consumption growth aggravates its greenhouse gas emissions, local air pollution and energy scarcity. In the 1990s, a large number of voluntary agreements emerged in industrialised countries in order to improve industrial energy efficiency. These experiences are now taken into account in China. This article analyses the drivers for voluntary agreements on industrial energy efficiency in China, based on a case study of three enterprises in Nanjing, Jiangsu Province. Furthermore, the article reviews the institutional set-up of energy policy and investigates the pertaining policy culture. From the findings, conclusions are drawn on the role of voluntary agreements within China's larger policy context. We conclude that opposed to avoiding stricter regulation, voluntary agreements in Nanjing are reinterpreted in view of more stringent national provisions on energy efficiency in the 11th Five Year Plan. Hence, agreements have evolved into an implementation tool of national policy at the local level. For industry, another major driver for participation was identified as improving its relations with local authorities. Voluntary agreements showed to have the potential to overcome traditional constraints of implementing top–down policies at the local level in China.     

Implementation of voluntary agreements for energy efficiency in China

Low-energy efficiency and environmental pollution have long been taken as key problems of Chinese industry, although a number of command-and-control and economic instruments have been adopted in the last few decades. In this paper, policy and legislation development for voluntary agreements were summarized. The voluntary agreements pilot project in two iron and steel companies in Shandong Province as well as other cases were analyzed. In order to identify the existing problems in Chinese cases, comparison was made between China and industrialized countries in the practices of energy efficiency voluntary agreements. Based on the analysis, detained recommendations, including the use of supporting policies for voluntary agreements, were raised. It is expected that voluntary agreements could play a more important role in energy efficiency improvement of Chinese industry.     

Planning versus implementation of energy-saving projects by industrial companies. Insights from the Dutch Long-Term Agreements

Companies participating in the Dutch voluntary agreements on energy efficiency are required to announce the energy-saving projects that they have planned for a specified reporting period in an Energy Efficiency Plan (EEP). All projects with a payback period less than 5 years should be implemented. The aim of this paper is to provide insight into the differences in planning and implementation of energy efficiency investments by companies. This analysis is based on the EEPs submitted in the period 2009–2012. By comparing the characteristics of projects that have been implemented with those that were planned, insight is gained in the adjustments that companies make in their energy efficiency investment plans. We look at external circumstances that could explain these adjustments. Our results show that over 12,000 projects have been planned by the 904 long-term agreement (LTA) participants, about half of which are planned ‘certain’, which means that companies are certain that these projects will be implemented. However, we find a large difference between the planned and realised savings of companies and a huge variation in the payback period of both planned and implemented projects. We do not find a correlation between implementation rate and payback period. This suggests that the payback period in the EEPs was not assessed properly or that other than economic motives are more decisive for investment decisions. Our results can be used to improve the effectiveness and efficiency of voluntary agreements.     

Green electricity policies in the Netherlands: an analysis of policy decisions

Over the last decades, fundamental changes can be observed in both market conditions and the national policy framework for green electricity in the Netherlands. The Dutch Government has regularly intervened in markets, demonstrating fundamental shifts in policy and approach. This study aims to analyse the developments in renewable energy policy making in the Netherlands. It assesses changes in the choice of policy instruments and target groups, the role of stakeholders, and offers explanations behind policy successes and failures. Dutch green electricity policy over the last decade can be characterised roughly by three phases: in the early 1990s, the government negotiated voluntary agreements with the energy distribution sector on targets for green electricity sales, which were never met. In the second half of the 1990s, a regulatory energy tax was introduced, from which customers of green electricity were exempt. This led to a substantial increase in demand, which was largely met by green electricity imports, and did not lead to additional domestic renewable energy capacity. Finally, a change in policy has taken place recently (2003) shifting the focus from promotion of demand to the promotion of supply through a system of regulated feed-in tariffs. Despite the renewable energy policies, growth of the renewable energy market in the Netherlands has been small and targets have not been fully met. The Dutch government has not yet succeeded in substantially reducing market uncertainties and in building confidence among market parties, because the policies have not been stable and policy objectives have frequently been partly ambiguous. In addition, the influence of stakeholders in renewable energy policy making has been small which has the early acceptance and implementation of alternative policies.     

Energy supplier obligations and white certificate schemes: Comparative analysis of experiences in the European Union

A number of Member States of the European Union (EU) have introduced market-based policy portfolios based on quantified energy savings obligations on energy distributors or suppliers, possibly coupled with certification of project-based energy savings (via white certificates), and the option to trade the certificates or obligations. The paper provides an up-to-date review and analysis of results to date of white certificate schemes in the EU.

The implementation of a multi-annual agreement for energy efficiency in The Netherlands

The paper analyses the implementation of the second multi-annual agreement for energy efficiency concluded in the Netherlands with industrial sectors for the period 2002–2010. It aims to investigate whether the multi-annual agreement MJA2, as a voluntary instrument, is sufficiently stimulating behavioral change at the target group level, and sustained transformation of production and management patterns towards significant gains in energy efficiency. The analysis uses a Structure–Conduct–Performance analytical framework for implementation processes in order to: (a) analyze the setting of implementation, actor roles, attitudes and interactions; (b) discuss emerging obstacles and positive experiences with the implementation of the three core policy instruments envisaged: energy management system, process efficiency measures, and ‘expansion themes’ measures. Based on this policy recommendations are formulated regarding voluntary agreements in general, using the Structure–Conduct–Performance framework of implementation analysis, and regarding how the implementation process of MJA2 in particular could be improved.     

Tradable white certificate schemes: what can we learn from tradable green certificate schemes?

In this paper, we analyze the experiences gained from tradable green certificate (TGC) schemes and extract some policy lessons that can lead to a successful design of a market-based approach for energy efficiency improvement, alias tradable white certificate schemes. We use tradable green certificate schemes existing in the Netherlands and Sweden as case studies. Departing from an assessment of both TGC schemes, we identify several institutional and market aspects that have affected their performance. We conduct the analysis by addressing key evaluation criteria (i.e., cost and energy effectiveness, administrative burden, technological innovation, political feasibility, and transaction costs). It is not our intention to demonstrate to the reader a normative aspect of designing tradable white certificate schemes. Rather, we identify some key policy lessons which can be summarized as: a binding long-term target must be clearly expressed in terms of policy time frame and certainty, a proper liquid market must be ensured for tradability of certificates, the scheme should be technology neutral, transaction costs should be kept low, and the energy efficiency target should not only address ‘low hanging fruits’ but also promote innovation.

Counting project savings—an alternative way to monitor the results of a voluntary agreement on industrial energy savings

In 2008, the Dutch voluntary agreements on industrial energy efficiency faced fundamental changes to their monitoring methodology. Where the old method was based on measuring the improvement of energy use per unit of production, the new method focuses on the energy savings from projects implemented by participating companies. Advocates of the new method claim that it gives a better view of the companies’ efforts to save energy, as it shows their deliberate changes in production processes, whereas opponents emphasise that the relation with ‘real’ energy efficiency is lost. By applying the two methods on the same group of companies, the results can be compared and show to what extent the choice of monitoring method affects the key message to policy makers. Of special interest is the relation between energy and production in the period 2008–2012, a period with large fluctuations in the level of production and energy use as a result of the economic crisis. The data show that energy-saving projects made a significant impact on energy use in the analysis period, although their effect is smaller than that of other factors such as fluctuations in production and in the number of participating companies. The old method shows a result for the period 2005–2013 that is less than half of that of the new method, mainly because of a decrease in efficiency during years of decreasing production. The analysis clearly shows that the two methods do not show the same development of energy efficiency improvement and should be presented as such.     

Evaluating public policy instruments in the Greek building sector

This paper applies a multi-criteria analysis (MCA) to evaluate public policy mechanisms that foster energy efficiency and renewable energy sources in the Greek building sector, based on stakeholders’ understanding and perceptions of the functionality of policy instruments. The objective is to shed light on the implementation of currently employed policy mechanisms that aim to achieve the 2020 energy savings targets and beyond, providing useful information to policy makers for future policy (re-) formulations. In this framework, policy instruments were evaluated against process-related criteria, such as implementation costs, distributional effects, and coherence of policy processes, so as to highlight successful policy practices during their implementation phase as well as to unveil cases of policy underperformance or unintended policy outcomes. To hedge uncertainties related to policy instrument selection, the method employs probabilistic evaluations of every alternative against each criterion. The MCA results showed that the country is still missing significant energy saving opportunities that could be reached through more streamlined implementation practices and political support. In times of fiscal crisis, the Greek government should also revitalize the implementation of alternative funding mechanisms and support policy alternatives such as green public procurement, voluntary agreements, and energy performance contracting.     

Implementation of energy efficiency projects by Dutch industry

As potentials for energy savings are huge, industry can provide a major contribution to energy savings goals. This paper focuses on the energy savings realized under the Dutch voluntary agreements in the period 2001–2011. Participants in these schemes are obliged to plan and implement all measures with a payback period of less than 5 years. This paper shows how many of these projects have been implemented and how much savings they generate. Our findings show that large differences exist in the realized savings between individual companies. There is however no significant difference in savings observed between companies that participate in the Emission Trading System (ETS) and companies that do not. Although it is impossible to disentangle the drivers behind the implementation of these projects, the amount of savings suggest that at least part of them was implemented because of different energy policy instruments.     

Regulatory and voluntary approaches for enhancing building energy efficiency

Buildings are the dominant energy consumers in modern cities but their consumption can be largely cut back through improving efficiency, which is an effective means to lessen greenhouse gas emissions and slow down depletion of non-renewable energy resources. However, the potential energy cost saving alone is hardly a sufficient incentive to investing into improvement measures, unless the cost of using energy soars. People's attitude will change with increasing concerns about the environment and sustainable development but the results remain insignificant. Surely, more effective means are needed to induce or compel greater efforts, especially to the signatories to the Kyoto Protocol. Whilst regulatory control is widely used, many believe that encouraging voluntary commitments is more cost effective in dealing with environmental problems. More researchers now favor the adoption of a well-articulated policy mix involving both regulatory and voluntary instruments. The paper describes a comprehensive literature review about regulatory and voluntary policy instruments related to building energy efficiency. Particular attention is given to the cost-effectiveness of these instruments, as reflected by the implementation experience of several countries, and a qualitative evaluation. The possibility and benefits of harmonizing governmental and private-sector schemes are discussed.     

How much market do market-based instruments create? An analysis for the case of “white” certificates

Among the diverse economic instruments to foster energy efficiency (EE) and climate protection, tradable certificates have been investigated for renewable energy, and the EU directive on an emissions-trading scheme for CO₂ certificates has been approved in 2003. In contrast, tradable energy efficiency—or “white”—certificates have only lately been considered as a market-based tool to foster EE as compared with standards and labelling, for example. Theoretically, there is little doubt about the advantages. In practice, however, some fundamental problems arise. Critical issues are the design of an efficient artificial market for white certificates, its compatibility with the European emissions-trading system, the identification of a suitable target group for an EE obligation and the measurement of energy savings as compared with a reference use of energy. We use the theoretical framework of transaction cost economics to elaborate these issues. We conclude that transaction costs and investment specificity will restrict markets for white certificates in practice. Long-term contracts rather than spot trade will be the prevailing form of governance for EE investments.     

Tradable white certificates: experiences and perspectives

The term white certificates refers to policy schemes that combine an end-use energy efficiency obligation on energy companies with a trading option.After summarizing its rationale, the paper focuses on the major issues and challenges in designing and administering a white certificates mechanism based on the comparison of the major active national schemes that emerged from the dedicated 2010 IEPEC panel session.     

Rationality of energy efficiency improvement targets under the PAT scheme in India – A case of thermal power plants

The market-based Perform Achieve and Trade scheme was introduced in India to enhance the energy efficiency of energy-intensive sectors, and for thermal power plants by reducing their specific energy consumption within the framework of a tradable certificate scheme. International experience suggests that effectiveness of such schemes is greatly influenced by the assigned targets of the obligated units. Setting rational targets is thus, a key aspect of successful implementation of the scheme. In the present study, we examine the rationality of the targets set for the power sector of India, based on comparing it with energy saving potential of the plants, and the targets assigned to the respective plants. Data envelopment analysis models are used to determine relative efficiency and energy saving potential. The study results indicate that in most cases, (i) The targets are much less than the actual potentials of the thermal power sector, (ii) There exist substantial inefficiencies within the system in both energy use and managerial dexterity; and (iii) If the sector realizes its full potential, then the Energy Saving Certificate market may witness a surplus of 4.7 million certificates on account of thermal power sector alone.     

Interactions of white certificates with other policy instruments in Europe

In a tradable white certificate (TWC) scheme, each certificate issued represents a certain amount of energy saved. Used in conjunction with an energy-saving obligation on certain parties in the energy supply chain and with rules for trading, monitoring and verification established, an efficient market for energy savings in sectors not covered by the European Union (EU) Emissions Trading Scheme can be established. However, a plethora of other mechanisms are already in place to promote a more sustainable use of energy in Europe. This paper analyses the interactions (both potential and realised in existing schemes) between TWCs and other policy instruments including tradable green certificates, the European Union Emissions Trading Scheme, the European Union Energy Performance in Buildings Directive as well as taxes, subsidies and loans. Measures implemented through a TWC scheme that reduce the consumption of electricity can make targets under a tradable green certificate scheme easier to attain. Where a tradable green certificate scheme contains relative targets, the target should be increased to achieve the same absolute amount of renewable power. A TWC scheme can also reduce the number of allowances electricity generators will need to surrender under the EU Emissions Trading Scheme. By reducing the available emission rights in the National Allocation Plans, this effect is possible to counteract.

Tradeable energy efficiency certificates in Australia

Tradeable energy efficiency certificates are created in Australia as part of a larger baseline-and-credit emissions trading scheme, the Greenhouse Gas Reduction Scheme (GGAS) that operates in the State of New South Wales and the Australian Capital Territory. GGAS aims to reduce greenhouse gas emissions associated with the generation and use of electricity through project-based activities to offset the production of emissions. GGAS applies in two jurisdictions that are part of a wholesale electricity market operating across a total of six jurisdictions and this imposes some constraints on scheme design. Nevertheless, GGAS has developed a set of comprehensive operational systems and procedures to validate energy efficiency projects and verify the abatement they produce. To the end of calendar year 2006, nearly ten million energy efficiency certificates have been created under GGAS, representing nearly ten million tonnes of CO2-e abatement. Some significant issues have arisen regarding the creation of certificates from the mass distribution of small energy-efficient household appliances. However, the experience with GGAS still demonstrates that tradeable energy efficiency certificates can be an effective mechanism for incentivising greenhouse gas emissions abatement in the context of a baseline-and-credit emissions trading scheme.
