Germany invests billions for crucial power lifeline

The 700 km Suedlink power transmission line is considered crucial to Germany's energy transition. Yet some argue that the multi-billion-euro project is too costly and raises concerns over ownership and environmental impact.

SuedLink, a 700-kilometer (434 miles) underground power transmission line, is a key part of Germany's energy transition strategy, designed to transport electricity from renewable sources between the country’s wind-rich north and the industrial south.

Supporters argue the project will modernize Germany’s outdated power network and help avoid annual grid intervention costs of €2 to €3 billion ($2.2 to $3.4 billion)  caused by renewable energy bottlenecks.

However, the €10 billion infrastructure project continues to face strong resistance from citizens' groups and environmental activists, who criticize its cost, land use, and ecological impact. Concerns over construction in forests, potential environmental damage, and property rights disputes have led to protests and legal challenges. Still, project developers maintain that SuedLink remains on track for completion and is expected to begin transmitting electricity within two years.
