Engineering giant GE and E.ON Climate & Renewables (EC&R) North America have signed a seven-year operation and maintenance (O&M) agreement covering a fleet of US wind turbines.

The O&M deal for 529 GE wind turbines is one of the largest wind services deals the company has ever signed.

The agreement is designed to maximise turbine availability and energy production across EC&R’s US installed base of GE wind turbines, E.ON said in a statement.

Under the agreement, GE will provide 24/7 remote monitoring and diagnostics from GE Power & Water’s Schenectady, New York-based Renewable Operations Centre.

It will also provide complete site services for all GE 1.5MW wind turbines installed at five EC&R project sites: the Pyron phase of Roscoe, Panther Creek I & II and Panther Creek III in Texas, Munnsville in New York and Stony Creek in Pennsylvania.

GE’s 1.5MW wind turbine is the world’s most widely deployed wind turbines, with more than 12,000 units now installed.

According to the American Wind Energy Association (AWEA), GE 1.5-MW wind turbines accounted for 43% of all new wind power capacity in the US last year.
