Ohau A - New Zealand

A major project milestone has been achieved with the installation of the first new excitation system at the Ohau A hydropower plant in New Zealand.

In June 2015, ANDRITZ HYDRO received an order from Meridian Energy Ltd. for the design, manufacturing, delivery, and commissioning of four static THYNE 5* excitation systems for the Ohau A station.

ANDRITZ HYDRO met the stringent timeframe of the contract in terms of design, manufacturing, and workshop testing. The new excitation systems were shipped on schedule and arrived at the powerhouse in late February 2016. Subsequently, installation of the first new excitation system followed. It has been successfully completed and was handed over to the customer in June 2016.

ANDRITZ HYDRO is looking forward to the completion of the other three excitation systems. Commissioning of the last installation is scheduled for mid-2017.
