Tenaska & Warburg Selling Electricity Plants

Tenaska Capital and Warburg Pincus have agreed to sell three electricity generation plants in Ohio, Pennsylvania and West Virginia to APT Generation. In additional, Tenaska will sell its Calumet Energy Power Station in Chicago. The combined sale price is $856.4 million.



Tenaska Capital Management, LLC (Tenaska Capital), manager of the Tenaska Power Fund, L. P. (TPF), announced today that a subsidiary of TPF and an affiliate of Warburg Pincus LLC (Warburg Pincus) have entered into an agreement to sell APT Generation, a portfolio of three electric generating plants in Pennsylvania, West Virginia and Ohio.


In addition, Tenaska Capital announced that TPF had entered into an agreement to sell the Calumet Energy Power Station, a 303-megawatt power plant in Chicago, Ill.


The four plants are being purchased by a subsidiary of International Power plc for a purchase price of US$856.4 million.

TPF is a private equity limited partnership of institutional investors held outside the holding company structure of Tenaska, an independent energy company based in Omaha, Neb. Warburg Pincus is one of the largest global private equity firms, with more than $35 billion of assets under management. TPF and Warburg Pincus have been joint owners of APT Generation since 2007. TPF has owned Calumet since 2005.


The acquisitions are expected to close by the end of the third quarter of 2008.


The three APT plants are the 625-megawatt (MW) Armstrong Energy plant in Armstrong County, Pa.; the 313-MW Pleasants Energy plant in Pleasants County, W.Va., and the 616-MW Troy Energy plant in Wood County, Ohio. The Pleasants and Armstrong plants are positioned to deliver power to the PJM energy grid; the Troy plant serves the Midwest ISO energy grid.

“The success of this transaction indicates the growing value of energy assets in the Middle Atlantic and Midwest regions,” said Dan Lonergan, senior managing director for Tenaska Capital Management, LLC, which manages TPF. “We are pleased that International Power has taken advantage of this excellent opportunity. All four facilities are well positioned to meet growing demand in attractive markets.”


Chansoo Joung, a Warburg Pincus managing director, concurred: “When we entered into the joint agreement with TPF to purchase APT Generation, we felt our similar goals and strict investment criteria would provide superior results, and this has been the case. By optimizing the productivity of these plants, our partnership has made them an attractive asset serving an area of growing demand.”
