Abstract
The McLachlan Power Station is the most recently commissioned power station to tap into the resources of the Wairakei Geothermal Field in the Central North Island of New Zealand. The 55 MW power station, based around a refurbished second-hand Fuji turbine-generator, was designed, constructed, and commissioned between August 1995 and November 1996. This paper explores the projectÃs background, the philosophy behind the decision to incorporate second-hand equipment into a new geothermal development, and the engineering design and project management approach that enabled the construction and commissioning of the plant within 16 months, and at half the cost of an equivalent new installation (including well drilling and steamfield development) is described.
