Fuji Electric
The original design involved two 23 MW refurbished Elliot turbine-generators but late in the design these were abandoned in favour of a newer Fuji Electric 55 MW system completed for the Geysers geothermal field in the U.S.A by the state of California, but never run. Despite the cost of conversion from the U.S.A standard of 60 cycles/sec. to the N.Z. standard of 50 cycles/sec. the resulting project was much cheaper than using new equipment.
