Promotion of Market Access for Renewable Energy in the Nordic Power Markets

摘要

This study investigates how renewable targets for the Nordic power market might be achieved at the lowest costs. The instruments investigated are fixed Feed-In Tariff, economically sound premium based Feed-In Tariff and shadow-prices for CO_2 emissions. We utilize a Real-Time Price based simulation model in the analysis. We show that even with strong assumptions regarding the Emission Permit Price the targeted level of wind power is not reached without Feed-In Tariffs. Emission Trading produces the lowest total emissions but with the highest total costs. From the studied instruments the most cost-efficient way to reach the targets for wind energy market shares is the premium based Feed-In Tariff. This tariff is also the most cost-efficient way to reduce CO_2 emissions.
