Onss Commissioned

On 30 November 2009, the Helgoland cable connection between the onshore substation at St. Peter-Ording and the island of Helgoland was commissioned, linking the island to the mainland electricity grid. The 30 kV, roughly 52–53 km long submarine cable, with around 5 MW capacity and costing about EUR 20 million, began supplying Helgoland’s approximately 1,300 residents, replacing local diesel generators which were retained only as reserve units and thereby improving supply security and environmental performance.
