Wairakei B station in Taupo has three 30MW generators that have been in operation for decades.
The majority of the geothermal fluid taken from the Wairakei field wells is now directed to the recently commissioned Te Mihi station. Therefore Contact Energy has undertaken a drive to improve efficiencies in the Wairaikei stations to produce the same amount of power from less supplied steam.
The NCG project encapsulates this idealogy by installing a NASH gas removal system (GRS) which reduces energy loss due to air leakage into the condenser. Therefore the same amount of power can be generated with less incoming steam.
