Dong Energy A/S, Denmark’s state- controlled utility, is leading a drive to cut offshore wind- power costs by as much as 40 percent by the end of the decade.
>“The cost of energy from offshore wind turbines must be reduced,” Bent Christensen, a vice president at Dong’s wind division, said in the statement. “We expect to find significant savings” by cutting the size of foundations and changing the way turbines are installed, he said. Offshore wind power costs about 2.7 times more than onshore turbines, according to Bloomberg New Energy Finance, which puts the cost at about $221 a megawatt-hour over the life of a project. Governments are seeking to reduce the expense of wind farms at sea to expand power supplies without adding to carbon emissions or building on land.<
