Tokyo, June 5, 2013 - Mitsubishi Heavy Industries, Ltd. (MHI) has received an order for a 440 megawatt (MW) natural gas-fired gas turbine combined cycle (GTCC) power generation system to be installed at the Carty Generating Station being constructed in Oregon for the Portland General Electric Company (PGE). A separate long-term service agreement (LTSA) for the plant was also signed. The high-efficiency GTCC system will feature a state-of-the-art MHI M501GAC gas turbine and an MHI steam turbine unit with 50-inch blades. The generating station is scheduled to go online in the summer of 2016.

The order was placed with Mitsubishi Power Systems Americas, Inc. (MPSA) by Abengoa, through its subsidiary in the US which is the engineering, procurement and construction (EPC) contractor for the power plant project. Abengoa is a globally recognized engineering company headquartered in Spain. The new power plant is being built near Boardman, Oregon, to meet the growing energy needs of PGE customers in the region.

The GTCC power generation system on order consists of an M501GAC gas turbine, a steam turbine, a heat recovery steam generator (HRSG) and a generator. The 501GAC gas turbine will be manufactured at MPSA's Savannah Machinery Works in Savannah, Georgia, and the SRT-50 steam turbine will be built at MHI's Takasago Machinery Works in Hyogo Prefecture in Japan. The generator will be supplied by Mitsubishi Electric Corporation. After the plant begins operating MPSA will provide the Carty Generating Station with comprehensive turbine maintenance, repair and outage services, replacement parts, and dedicated gas turbine remote monitoring under the LTSA.

The M501GAC gas turbine is one of the most efficient, large-capacity gas turbines in the world. MHI has received orders for 77 units of the G series worldwide, including 39 units in North America. The current order reflects this excellent track record, as well as the M501GAC gas turbine's reputation for superior performance. The next-generation SRT-50 steam turbine features 50-inch blades (at the last stage of the rotor) constructed of high-strength material, and offers higher performance and generation capacity at lower cost than units with smaller blades.

PGE is a fully integrated electric utility that operates numerous power plants in Oregon. In addition to generating power, it also buys, sells, transmits, and distributes electricity, and buys and sells natural gas. PGE also operates an MHI-supplied GTCC power generation system at its Port Westward Plant, which was delivered in 2008.

Gas turbine combined cycle power plants generate electricity in two stages through the combined use of gas and steam turbines. By using high-temperature exhaust from the gas turbine to produce the steam that drives the steam turbine, combined cycle power plants achieve higher thermal efficiency, lower fuel consumption, and lower emissions.

MHI has already delivered many GTCC power generation systems in Japan and other countries, and enjoys a solid reputation for its technological expertise and delivery track record. With the additional momentum provided by this latest order, MHI looks to further strengthen its GTCC power generation system marketing activities in the future.
