Dong Energy has confirmed that Papenburg-based construction company Johann Bunte has been contracted for the expansion of its operations and maintenance base in Norddeich in the German state of Lower Saxony.

The new building is needed to coordinate the construction of the consented 448MW Borkum Riffgrund 2 project.

Dong said the cost of the new building is expected to be about €5.2m.

The existing O&M base, which was inaugurated in April 2015, is 80 metres long and 15 metres wide and includes offices, recreation rooms, a canteen and a four-storeyed warehouse.

The Danish developer uses the current facility to coordinate O&M of its 312MW Borkum Riffgrund 1 and 582 Gode Wind 1&2 wind farm projects.
