On November 4, 2024, Sweden's government announced the cancellation of 13 planned offshore wind farms in the Baltic Sea due to security concerns, particularly regarding their potential interference with military sensors and radar.

Sweden's recent accession to NATO has further intensified its focus on military preparedness in the Baltic Sea, leading to increased security measures around strategic areas like Gotland.

While the government has canceled most offshore wind projects, it has approved one wind farm off the western coast, indicating a selective approach to renewable energy development.

In response to the regional threats, NATO has established a new military base in Rostock, Germany, aimed at coordinating member forces to counter Russian aggression.

Energy Minister Ebba Busch described the cancellation of the wind farms as a "hard choice," asserting that security policy must take precedence over energy expansion efforts.

Despite the setback to its renewable energy ambitions, Sweden's electricity consumption is projected to reach at least 300 TWh by 2045, which is double the current levels, highlighting a conflict between energy goals and defense priorities.

A report from the Defense Ministry stated that there are "no conditions for the establishment of wind power plants" in large parts of the Baltic Sea, reinforcing the government's decision.

Sweden plays a crucial role for NATO in the Baltic region, acting as a bridgehead towards the Baltic states and possessing significant reconnaissance capabilities.

The cancellation of these wind farms is heavily influenced by the ongoing regional security situation, particularly the threats posed by Russian hybrid warfare tactics targeting underwater infrastructure.

The proposed wind farms were to be located off Sweden's eastern coast, stretching from the Åland Islands to the Öresund strait near Denmark, but their rejection impacts Sweden's renewable energy goals.

Defense Minister Pål Jonson highlighted that these wind turbines could hinder Sweden's ability to detect threats such as cruise missiles and submarines, emphasizing the need for heightened military readiness.

This decision comes amid escalating security tensions in the region, particularly following Russia's invasion of Ukraine in 2022, which has prompted Sweden to reassess its defense strategies.
