An energy union without interconnections? Public acceptance of cross-border interconnectors in four European countries

Despite the importance of achieving a functioning and decarbonised European Energy Union (EnU) research addressing the public acceptance of cross-border energy interconnections at a European-wide level based upon public opinion polls is limited. To try to fill this gap in the literature, this article relies on a poll with 4000 respondents from the four big EU energy markets: France, Germany, Italy and Spain, including as a new explanatory variable their proximity to an electrical cross-border substation. Overall, 57,4% respondents have not heard about energy interconnections, and 69,2% have not ever heard about the internal energy market. Approaching public acceptance from a procedural justice framework, the article considers procedural justice as a pre-condition? For a fair policy-making process. By addressing the public acceptance of cross-border energy interconnections, the article aims to contribute to the existing literature on their linkages of said interconnections with the European energy policy-making process, deriving specific policy implications to foster cross-border interconnections and energy integration within the EnU.
