Another Milestone Achieved for PPM's Twin Buttes Wind Power Project

LCG, September 7, 2007--The dedication ceremony for the Twin Buttes Wind Power Project is scheduled for next week. PPM Energy developed the 75-MW wind farm, and Xcel will purchase the power generated. Construction began in the fall 2006, and the project began generating power in July of this year.

The Twin Buttes Wind Power Project is located in southeastern Colorado in Bent County. The wind farm includes fifty, 1.5-MW turbines manufactured by GE. The turbines are installed over a 9,000 acre site that will remain ranchland. The estimated cost of the project is $100 million.

PPM Energy also jointly owns another wind farm, Colorado Green, in the vicinity with Shell WindEnergy Inc. Colorado Green, which is located in Prowers County, Colorado, consists of 108 GE Wind Energy 1.5 MW turbines and has a generating capacity of 162 MW. Shell WindEnergy and PPM Energy own the project in a 50/50 joint venture.
