Alstom to refurbishment New Zealand’s biggest hydro plant

23 July 2002 – Alstom has been awarded a €15m order by Meridian Energy Ltd. of New Zealand for the uprating and refurbishment of seven hydro generators (135 MVA each unit) at the Manapouri Hydro Power Station, located on the Southern Island of New Zealand.

The goals of the refurbishment project are to extend equipment life, improve plant reliability and performance, and reduce maintenance costs. Under the terms of the contract, Alstom will provide engineering, supply and installation of generator replacement stators, extensive rotor refurbishment and replacement of auxiliary components and systems.

Site work will start in March 2003 and is scheduled for completion at end of 2005. Alstom’s hydro divisions in New Zealand and Switzerland are jointly responsible for the execution of the project.

Manapouri is New Zealand’s largest hydropower station, supplying most of its generated energy directly to a nearby aluminum smelter. The plant was originally commissioned between 1969 and 1971, with the machines installed in an underground hall 200 meters below the Lake Manapouri National Park.

Alstom also has ongoing maintenance contracts for several other hydropower stations owned by Meridian Energy Ltd.
