Country: Mexico

Client: Kyushu Electric Power Company, Inc. (Kyushu EPC)

Financial source: Kyushu EPC

Service Period: June 2001 to March 2003

1. PROJECT DESCRIPTION

The Tuxpan-II plant (495 MW) features two Mitsubishi Heavy Industries 501F gas turbines with one steam turbine and seawater cooling. It commenced commercial operation on December 15, 2001. The plant was developed by Electricidad Aguila de Tuxpan, a venture of Mitsubishi Corporation and Kyushu Electric Power Co., Inc. The two companies jointly maintain and operate the plant for 25 years under a power purchase agreement with the Comision Federal de Electricidad. Project finance was provided by the Japan Bank for International Cooperation (JBIC) and commercial banks.

2. SERVICES provided by WEST JEC

3. OUTLINE OF THE PLANT
The plant is located on the seaside of the Gulf of Mexico in the southern part of Tuxpan City. Its designed capacity is 495 MW. The plant uses a 2-on-1 configuration with two M501F gas turbines connected to their respective heat recovery steam generators (HRSGs), and with the steam from both HRSGs supplying a steam turbine. An offshore intake and discharge system has been provided as the cooling system for the turbine exhaust steam flow. The gas turbine generators, installed indoors, are able to burn dual fuels of natural gas and diesel oil with DLN (Dry Low NOx) combustors. The triple-pressure HRSGs are of the reheat type, natural circulation. Evaporative cooler systems are made available to cool inlet air, thereby improving the plant's power output especially during the summer months. The gas turbine operations are monitored by MHI in Japan, using the Remote Monitoring System to ensure proper operations.
