Invenergy Completes Construction of Third Phase of Grand Ridge Wind Project in Illinois

Invenergy Wind LLC (“Invenergy”) announced the successful closing of a construction loan for its 100.5 MW Grand Ridge Energy II & III
wind farm in La Salle County, Illinois, about 80 miles southwest of Chicago. The facility is currently under construction and is an expansion of Invenergy’s Grand Ridge wind farm that went into operations in October 2008.

The construction debt facility and term facility were underwritten by Bayerische Hypo-Und Vereinsbank AG, a unit of UniCredit Group, and Dexia Credit Local.
The Grand Ridge expansion will interconnect with ComEd and will sell its output under a 20-year power purchase agreement with Appalachian Power Company, a subsidiary of American Electric Power (“AEP”). The Grand Ridge expansion will be powered with 67 General Electric 1.5 MW SLE wind turbines.

Construction of Grand Ridge expansion is being managed by Gemma Renewable Power, LLC (“Gemma Renewables”). Gemma Renewables is a joint venture between Invenergy and Gemma Power Systems LLC, a subsidiary of Argan, Inc. Full commercial operation of the facility is scheduled for the third quarter of 2009. The wind farm will be owned and operated by Invenergy.

Officials with LaSalle County, with Brookfield, Allen, Grand Rapids and Otter Creek Townships and with Exelon Corporation all provided key support to this project.

Invenergy and its affiliates are focused on the development, ownership, operation and management of large-scale wind sites and other clean energy generation assets in the North American and European markets.

The Invenergy companies have approximately 2,000 MW of wind power projects and 2,200 MW of natural gas-fired generating projects in operation.
