Joint Support and Efficient Offshore Investment: Market and Transmission Connection Barriers and Solutions

Different support schemes are applied for the promotion of renewable energy sources in EU Member States. Current EU legislation opens opportunities for international cooperation to achieve national renewable targets more efficiently, either by statistical transfers, joint projects or joint support schemes. This article investigates their interplay with support schemes and applies the results to offshore wind energy. With all North Sea neighbouring countries planning offshore wind installations and considering a coordinated offshore grid, this constitutes a good starting point for coordinated action. Two case studies on the regulatory combinations of joint projects financed under tendering and tradable green certificates as a joint support scheme are contrasted, addressing main barriers and possible solutions. Joint projects are an interesting option in the midterm, whereas joint support schemes may be more attractive on a longer time horizon.
