400 MW Combined-Cycle Plant Order for MHI Consortium

Posted on September 8, 2004

A consortium of Mitsubishi Heavy Industries, Ltd. (MHI) and Downer Engineering Power Limited of New Zealand, have received a turn-key order from Genesis Power Limited, a New Zealand state-owned electricity company, to build a 400 MW gas turbine combined-cycle (GTCC) power plant at the company's Huntly Power Station. Financial details of the project were not disclosed. The natural gas GTCC plant, targeted for start-up by the end of 2006, is to consist of one MHI M701F gas turbine, one heat recovery steam generator (HRSG), one steam turbine and one generator. The gas turbine will be manufactured at MHI's Takasago Machinery Works and the steam turbine at its Nagasaki Shipyard and Machinery Works; the generator will be made by Mitsubishi Electric Corporation.

Downer Engineering Power, a subsidiary of Australia-based Downer EDI Limited, will take charge of civil work, equipment installation, and manufacturing and procurement of the HRSG and other peripheral equipment. Mitsubishi Corporation, a trading company, will also participate in the project. The order is the first GTCC project for MHI from New Zealand. In addition to plant construction, MHI also signed an LTSA to undertake maintenance and repair work during a specified period of time after the plant goes on-stream.

The Huntly Power Station, New Zealand's largest thermal power plant and is located approximately 100 km south of Auckland. The station already has four power units in operation, each generating 250 MW and all units are capable of burning coal, natural gas, or a combination of the two. The new GTCC plant will be built next to the existing facilities. The electricity generated will be supplied to Auckland.
