NEW YORK (AP) - General Electric says it has received a $1.4 billion contract to supply wind turbines and related services for a wind farm project that is expected to be the largest ever.

The company says the order from independent power producer Caithness Energy is the largest ever for its 2.5xl wind turbines. It will install 338 of the turbines, which are already in use in Europe and Asia, between 2011 and 2012.

GE will also supply 10 years of operational and maintenance services.

The 845-megawatt Shepherds Flat project, located in Oregon, has received most of the government permits it needs to run. Construction will start next year and is expected to be finished in 2012.
