Economy The project was conceived in February 2008, as part of the Danish government's Energy Policy Agreement. The wind farm cost an estimated 10 billion
Danish kroner (€1.35 bn, US$1.65 bn). During operation, DONG receives a
feed-in tariff of 1.051 DKK/kW·h (17 US¢/kW·h) for the first 20 TW·h (about 12–13 years of production), whereas the 207 MW
Rødsand 2 receives 0.629 DKK/kW·h for 10 TW·h.
DONG Energy was the only bidder for the project, and received the license to build it in 2010. Newsmedia and politicians suggest a tight schedule with tough sanctions as reasons for the single bid and higher price, and the subsequent
Horns Rev 3 offshore wind farm had 4 bidders in 2015 and costs 0.77 DKK/kW·h, well below the 105 øre at Anholt.
Technology DONG contracted
Siemens Wind Power to supply 111 3.6 MW
wind turbines for the project, placed in water depth. A platform holds 3 transformers which increase voltage from 33 to 220 kV for transporting the
alternating current power to land through a single 3-conductor cable (diameter ) and a further to Trige (near
Aarhus) where a 400 kV main power hub can distribute the power. There are
switchyard reactors along the cable to provide
reactive power to compensate for line capacitance. The agreement required first power to be produced before the end of 2012, and be fully commissioned before the end of 2013. Usually, turbines are placed in a grid pattern of lines and rows. But the turbines of AOWF are placed in an unusual pattern, governed by two principles: put most of them along the edges, and put most in undisturbed airflow from the main direction, which is
West-southwest. This would increase production by 1.5%, a lifetime value of more than 100m DKK. ==Construction==
