CHICAGO (Dec. 16, 2015) – Invenergy Wind LLC (“Invenergy”), the largest privately-held independent wind power generation company in the United States, today announced the sale of 832 (net) megawatts (MW) of wind power plants to TerraForm Power, Inc., an owner and operator of clean energy power plants. Today’s announcement represents the closing of a purchase and sale agreement originally executed on June 30, 2015. A final closing for an additional 98 MW (net) of projects is scheduled to be completed in early 2016. Proceeds from the transaction will be reinvested in Invenergy’s industry-leading development pipeline. The total enterprise value of the transaction is more than $2 billion.

The closing encompasses four power plants, representing 754 MW (net) in the United States and one 78 MW project in Canada. As part of the agreement, Invenergy is retaining an approximately 10 percent equity interest and will continue as the operations and maintenance provider for the U.S.- based projects: California Ridge, Bishop Hill, Prairie Breeze and Rattlesnake. Invenergy and other owners sold 100 percent interests in the Canadian project, Raleigh.

“We are pleased to complete this transaction with TerraForm Power,” said Jim Murphy, Invenergy’s Chief Financial Officer and Operating Business Group President. “We look forward to our continuing ownership and operating role with these high-quality projects.”
