Atlantic Power Announces Purchase of Additional Interest in Canadian Hills Wind Farm

Atlantic Power Corporation announced the purchase of an additional 48% interest in the Company’s Canadian Hills wind power project in Oklahoma (the "Project") and the close of a $310 million non-recourse, project-level construction financing facility for the $470 million Project, for which Morgan Stanley serves as sole lead arranger.

The financing includes a $290 million construction loan and a $20 million 5-year letter of credit facility. The construction loan is structured to be repaid by a tax equity investment when the Project commences commercial operations. With this closing, the Company owns 99% of the Project and is committed to investing approximately $180 million of equity (net of financing costs) following the funding of the construction financing. Morgan Stanley is also providing bridge financing commitments that backstop the Company’s equity investment and a portion of the tax equity investments.

Canadian Hills is an approximately 300 MW wind power project located near El Reno, Oklahoma, 20 miles west of Oklahoma City, Oklahoma. The wind turbines project was developed by Apex Wind Energy Holdings, LLC ("Apex"), a leading wind energy company based in Charlottesville, Virginia. Apex will retain a 1% interest in the Project. Apex will manage construction of the Project and the Company will oversee operations and be the asset manager. The Project is expected to generate enough clean, renewable energy to power the equivalent of over 100,000 homes.

"Our investment in Canadian Hills is a significant milestone in the continued growth of the Company", commented Barry Welch, President and CEO of Atlantic Power. "We were able to leverage our strong industry expertise to secure and finance a transaction that will increase our net MW ownership by 13% and provide steady, accretive cash flows over the next twenty years. The investment will increase the Company’s average remaining power purchase agreement life from 8.3 years to 9.9 years and increase the wind segment of our net generating capacity from 3% to 15% while reducing the gas segment from 77% to 68%."

Construction under the terms of a fixed-price, balance of plant contract will begin immediately and the Company expects the Project to be fully operational by November 2012. The Company’s equity contributions are expected to be drawn following disbursement of the construction loan, and is anticipated to be a combination of convertible debentures and common equity.

The Company has the ability to use its existing revolving credit facility and the approximately $360 million bridge facility from Morgan Stanley to provide flexibility in the timing of the tax equity and permanent capital raise. Upon commencement of commercial operations of the Project, the construction loan is expected to be fully repaid by the tax equity investment. Cash distributions to the Company from the Project are expected to average $16 to $19 million for each full year of operation through 2020, which is net of the portion of the cash allocated to tax equity. Following completion, the Project will also have a positive impact on reducing the Company’s consolidated leverage and improving credit metrics such as consolidated debt to EBITDA.

The Project has long-term power purchase agreements for 100% of its output with Southwestern Electric Power Company, Oklahoma Municipal Power Authority, and Grand River Dam Authority. The wind farm will deploy Mitsubishi 2.4 MW MWT102 and REpower 2.05 MW MM92 wind turbines, both proven technologies that take advantage of the Project’s strong wind regime.
