Cost-efficiency, risks and system integration incentives of premium-based feed-in tariffs in Austria
Abstract
This working paper assesses, how the feed-in support policy in Austria can be re-designed, to increase cost-efficiency and the incentives for system-integration of renewables. We present the existing feed-in tariff system, show the success in terms of renewable expansion in Austria, and assess which deployment scenarios for renewables are realistic in Austria up to 2025. Afterwards, we comprehensively present different forms of premium feed-in tariffs and assess, using existing literature, how they affect cost-efficiency and system integration. Premium tariffs with monthly and yearly floating pricing mechanisms, with price-floors and caps and with special mechanisms to lower production under negative price regimes are compared. In a second part we analyze, how a premium system has to be designed to guarantee a stabile expansion under planable costs and a minimization of social conflicts among neighbours of projects. Determining the premium in the tariff systems by auctioning or by administriatively regulating tariffs is discussed in the third part. In a final conclusion, we give recommendations for the design of a future feed-in tariff system in Austria.
