Vestas receives 400 MW order in the USA                                         

Vestas has received an order for 242 units of the V82-1.65 MW wind turbine in   
the USA. Horizon Wind Energy has placed the order, and the wind turbines, which 
will have a total installed capacity of 400 MW, will be delivered to Horizon    
owned wind projects in the USA.                                                 

Horizon Wind Energy LLC, headquartered in Houston, Texas, is a leading wind     
project developer and a fully owned subsidiary of Energias de Portugal, S.A., a 
major Portuguese utility and one of the world's largest generators of           
electricity from renewable energy sources. By the end of 2007, Horizon will have
developed more than 2,200 MW and will be operating wind power plants with a     
total installed capacity of over 1,500 MW. Horizon is currently developing a    
portfolio of more than 10,500 MW in over a dozen states.                        

Vestas will supply and commission the turbines, and the order also comprises a  
five-year service and maintenance agreement. Delivery is expected to begin at   
the end of 2008 and will continue through 2009.                                 

“Vestas is proud to announce this 400 MW order which confirms the performance   
and reliability of the V82-1.65 MW turbine in the North American market. We are 
also very pleased to be adding additional V82-1.65 MW turbines to Horizon's     
existing portfolio,” says Jens Søby, President of Vestas Americas A/S. “The     
strong and longstanding relationship between Vestas and Horizon is an important 
driver for the expansion of wind power in the USA and is further proof that wind
power is a competitive generating technology. Wind power helps fight global     
warming, fuels economic growth and creates thousands of new local jobs.”        

The above order does not affect Vestas' expectations for 2007 and 2008, cf.
