ALLETE Clean Energy (ALLETE) finalized the purchase of wind farms in Minnesota, Iowa and Oregon from AES. ALLETE acquired the operating wind energy projects for $27 million and all three wind farms - with a total output of 231 MW - have PPAs in place for their entire electric output. ALLETE also signed in November an option agreement to acquire a fourth wind farm from AES in mid-2015. Pursuant to that option agreement, ALLETE will have an option to acquire the 101MW Armenia Mountain, Penn., wind farm. That project became operational in 2009 and has two long-term PPAs in place.
