Sweden has escalated tensions with the EU regarding congestion fees, threatening to cut electricity exports to Denmark. The European Commission has proposed that starting in December, 25 percent of these congestion fees should be allocated to EU-supported energy projects, a move not welcomed by Swedish Energy Minister Ebba Busch. In a meeting with European energy ministers, she expressed her discontent, likening Sweden's current stance to that of a 'bad girl' as they seek to protect their revenue from hydroelectric power.

The congestion fees are tariffs imposed on transmission companies when electricity is transported between regions with different pricing structures. These fees have become a contentious issue between Sweden and the EU, particularly as Sweden has profited considerably from its abundant hydroelectric resources. Much of Sweden's electricity comes from its northern hydroelectric plants, which must cross transmission boundaries to reach the more populous southern regions, leading to significant revenue for the state.

Norway has also expressed its opposition to the EU's proposed measures, indicating that the situation is affecting regional relations over energy management. As energy security becomes increasingly vital, both Sweden and Norway are scrutinizing the EU's plans that could undermine their control over revenues from electricity exports, highlighting the ongoing complexities in European energy politics.
