Calpine Set to Commence Full Commercial Operation of Greenfield Energy Centre in Canada

---

Researched by Industrial Info Resources (Sugar Land, Texas)--Greenfield Energy Centre LLC (Sarnia, Ontario), a 50:50 joint venture between Calpine Canada Power Ltd (Calgary, Alberta), a subsidiary of Calpine Corporation (NYSE:CPN) (San Jose, California), and Mitsui & Company Limited (NASDAQ:MITSY) (Tokyo, Japan), has completed construction and is scheduled to commence full commercial operation of the $600 million, 1,005-megawatt Greenfield Energy Centre in Sarnia, Ontario.

Construction of the project started in late 2005 and was completed this summer. The project is scheduled to commence full commercial operation today. The project consisted of constructing a 3-on-1 combined-cycle power plant equipped with three natural-gas-fired 184-megawatt (MW) Siemens Westinghouse Power Corporation SGT6-5000 W501FD2 combustion turbines with dry low NOx burners, three duct-fired Deltak heat recovery steam generators and a 453-MW Toshiba International Corporation condensing steam turbine generator. The project will also feature state-of-the-art emissions technology such as a selective catalytic reduction system for controlling nitrogen oxide exhaust emissions.

The plant will be connected to the existing Hydro One Lambton Transformer Station through two 230-kiloVolt overhead circuits that will feed the power into the Ontario electricity market. A wet mechanical draft cooling tower will be implemented for plant cooling, while processed water will be taken from the St. Clair River and treated by an onsite water treatment plant in order to facilitate the plant's water demands.

Burns & Roe Enterprises Incorporated, headquartered in Oradell, New Jersey, provided the turnkey engineering, procurement, and construction services for the project. Wood Group Power Operations Incorporated (Alpharetta, Georgia), a subsidiary of Wood Group (John) plc (LSE:WG) (Aberdeen Scotland), will operate the facility when it is completed.

(HOUSTON, Texas, SAN JOSE, Calif. and TOKYO, Japan) October 17, 2008 -- Calpine Corporation (NYSE: CPN) and Mitsui & Co., Ltd. announce the completion of construction and commercial operation of the Greenfield Energy Centre (Greenfield), located in Courtright, St. Clair Township, near Sarnia, Ontario, Canada. Greenfield is a limited partnership between subsidiaries of Calpine and Mitsui, each of which hold a 50 percent interest in the project.

"We congratulate the Greenfield project team for the successful completion of this important new energy resource," said Calpine Chief Executive Officer Jack Fusco. "We appreciate the opportunity to have worked with Mitsui and Ontario Power Authority to provide Ontario with a cost-effective, energy-efficient, reliable and low-carbon solution to the region's growing electricity needs."

"We are delighted to announce the completion of Greenfield Energy Centre and to contribute to meet the growing electricity demand in Ontario. We have had the pleasure of working with Calpine and Ontario Power Authority on this project which will be providing Ontario with reliable long-term clean energy," said Mitsui Executive Managing Officer Takao Omae.

In 2005, Greenfield was awarded a 20-year clean energy supply contract with the Ontario Power Authority (OPA) to construct and operate the 1,005-megawatt combined-cycle power plant. Greenfield provides energy and capacity to the Independent Electricity System Operator of Ontario. Under the terms of the contract, OPA guarantees revenue equivalent to a fixed monthly payment, plus payment for variable operations and maintenance costs based on actual electricity generation.

The plant is a clean and highly efficient combined-cycle facility fueled by natural gas and is equipped with advanced air emission controls including Dry Low-NOx combustion, Selective Catalytic Reduction technology and a continuous emission monitoring system. With the use of clean-burning natural gas, combined with its high level of thermal efficiency, Greenfield is a relatively low-carbon electric generating facility that will produce approximately half as much carbon dioxide per megawatt-hour of electricity as an older coal-fired power plant.

Greenfield is financed by an 18-year, CAD550 million non-recourse project term loan, co-arranged by BMO Capital Markets, a business unit of BMO Financial Group, and The Bank of Tokyo-Mitsubishi UFJ, Ltd.
