    The core objective of this paper is to elaborate on historically implemented promotion strategies of renewable energy sources and the associated deployment within the European electricity market. Hence, at a first glance, the historic development of renewable energy sources in the electricity (RES-E) sector is addressed on Member State and on sectoral level as well as consequently discussed according to available RES-E potentials and costs. The specific focus of this paper, are promotion strategies for RES-E options as they are the key driver of an efficient and effective RES-E deployment. Therefore, the paper depicts the main types of different promotion schemes and their properties. Additionally, several cases studies of different European Member States show an in-depth analysis of the different RES-E promotion schemes. In this context, special emphasises are put on the question of effective and efficient promotion scheme designs of different RES-E technologies. Generally, conducted research led to the conclusion, that technology specific financial support measures of RES-E performed much more effective and efficient than others did. Hence, it is not all about the common question of feed-in tariffs vs. quota systems based on tradable green certificates, but more about the design criteria of implemented RES-E support schemes.

    This book was written in the frame of the OPTRES project, which was supported by the European Commission within the framework of the Intelligent Energy for Europe programme. The consortium, consisting of six European partners, analysed the effectiveness as well as the economic efficiency of currently implemented support schemes for renew-able energies in the electricity sector (RES-E) in the enlarged European Union. The analysis gives recommendations for future improvements of the existing RES-E promotion measures. Furthermore the consortium carried out an extensive stakeholder consultation, focussing on the identification of existing market barriers to the development of renewable electricity in the EU. The effectiveness and efficiency of current and future RES-E support schemes were analysed with particular focus on a single European market for renewable electricity products. Current best practices were identified and an assessment made of the (future) costs of RES-E and the relevant support necessary to initiate stable growth. The main barriers to a higher RES-E deployment as perceived by market actors and stakeholders were assessed.

    To meet existing and future targets for renewable energy sources, national governments, EU policymakers and electricity market stakeholders have a pronounced interest in designing optimal instruments for the promotion of Renewable Energy Sources in the Electricity sector (RES-E). This paper characterises the present status of the RES-E markets in Europe, the portfolio of promotional instruments currently applied across the EU and the progress the Member States have made in reaching the targets. In particular, existing support schemes are analysed in terms of their effectiveness in achieving additional RES-E generation and in terms of their ability to meet the targets at minimum costs (efficiency). Our empirical findings show that instruments which are effective also tend to be efficient. Further, the short- and long-term diffusion of specific RES technologies depends on the support schemes in place. Finally, the paper discusses the compatibility of different instruments to support RES-E in the context of more general energy policy objectives.

    On the success of policy strategies for the promotion of electricity from renewable energy sources in the EU

    In recent years, a wide range of strategies has been implemented in different EU-countries to increase the share of electricity generation from renewable energy sources. This paper evaluates the success of different regulatory strategies. The most important conclusions of this analysis are: (i) regardless of which strategy is chosen, it is of overriding importance that there should be a clear focus on the exclusive promotion of newly installed plants; (ii) a well-designed (dynamic) feed-in tariff system ensures the fastest deployment of power plants using Renewable Energy Sources at the lowest cost to society; (iii) promotion strategies with low policy risks have lower profit requirements for investors and, hence, cause lower costs to electricity customers.
