Xcel's announced it's adding another 775 MW of wind onto its Colorado system, to become the country's largest wind energy user. To put this in perspective, my colleague just put out an excellent study of the North American market. Xcel has ramped up its wind purchasing big time to become second in the US over the past two years, behind Southern California Edison.
But, despite the big wind announcement (actually outweighed by its 1,300 MW of CCGT capacity planned through 2012), Xcel has had to stall one of its own developments this year due to climbing turbine prices despite booming demand for its retail wind power offering. The firm is heavily reliant on development partners like Invenergy, Cielo and Padoma to get that capacity up and running - do these guys all have turbines lined up? Looks like Invenergy will come through in 2006 with 60 MW at least, though reaching 775 MW by 2007 will be challenging - as Xcel mentions with a heavy disclaimer at the end of the press release.
Still, hats off to Xcel for putting wind at the center of its supply strategy next to gas, and reaping its value on the retail side. These are the type of utility moves that fulfill state RPS quotas and keep up momentum for a long term PTC.
