Power Through Pressure: How Interconnection Became Part of the EU's Overarching Climate and Energy Policy

Interconnection is important to attain several important EU climate and energy targets. Drawing on data from 56 stakeholder interviews, stakeholder event participation and document studies, this study enquires as to why electricity interconnection became a part of the EU's overarching climate and energy policy in 2014. The theoretical approaches liberal intergovernmentalism (LI) and the advocacy coalition framework (ACF) are tested complementarily. LI received support: member states, particularly Portugal and Spain, were essential for the outcome. These successfully played the veto card in the high‐level negotiations for the 2030 Climate and Energy Policy Framework, leading to the first inclusion of concrete interconnection targets in it and interconnection becoming a European Commission priority. ACF received partial support: a ‘green’ long‐term, multi‐level advocacy coalition consisting of the renewables industry, environmental organisations and others promoted a binding target for electricity interconnection. This ‘green’ advocacy coalition was instrumental in aiding Portugal and Spain.
