ON THE EFFECTIVENESS OF FEED-IN TARIFFS AND TGCBASED QUOTAS FOR INCREASING THE SHARE OF ELECTRICITY FROM RENEWABLES

摘要

Currently, a wide range of strategies is implemented in different countries to increase the share of renewable energy for electricity generation. In this paper the preliminary results of the project ELGREEN funded by the EC are presented. The most important conclusion of this project are: 1. feed-in tariffs are an optimal instrument if a policy is introduced on a national level and if the rates are optimally designed 2. Of high relevance for quotas based on tradable certificates is that the penalty for not purchasing a certificate is higher than the worst case of investment, and that the planning horizon is guaranteed with high credibility;
