Mid-March 2023, we have installed the rotor in Unit 2 at Karapiro Hydro Power Station, on the Waikato River in New Zealand.


With the stator, thrust bracket and water lubricated runner hub already placed we’re in good position for final assembly and commissioning.

Congratulations to the entire ANDRITZ and @MercuryNZ teams for the excellent collaboration!


02/12 2022: Karapiro, New Zealand – 30 tons of steel

At Karapiro, New Zealand the ANDRITZ and @Mercury team have reached a major project milestone, with the first new piece, the runner chamber and bottom ring being lowered into place for test fit.


This has approximately 30 tons of stainless steel and will be aligned and levelled to fractions of a millimeter by the specialists at ANDRITZ before being welded to the existing draft tube liner and then concreted in place.

08/03 2022: Tekapo B, New Zealand - Turbine upgrade project installation complete

The last turbine at Tekapo B has been commissioned in February 2022 and has recently successfully completed its endurance run.


ANDRITZ is proud to have delivered another high efficiency turbine to a New Zealand customer. 

At the end of 2016, ANDRITZ was awarded a contract for the refurbishment of the Tekapo B hydropower plant located at Lake Pukaki at the end of the Tekapo Canal in the South Island, New Zealand. The plant has two vertical Francis units with a combined capacity of about 160 MW. The owner, Genesis Energy, is one of the largest electricity generators and retailers in New Zealand. It owns a generation fleet comprised of thermal, hydro and wind generation, with a total MW generation capacity of 1,651 MW. 

The upgrade significantly improves the efficiency of the turbine, reduces maintenance and complexity by eliminating the relief valve and has significantly improved hydraulic stability and vibration of the machine. The installation works included installing the new turbine parts, maintenance works on the generator stator and rotor, and repair of the retained parts. 

This is another major project completed by ANDRITZ's installation team in New Zealand and has again demonstrated our commitment to partnering with our customers to deliver a high-quality machine assembly in the challenging COVID environment.

Output: 2 x 80 MW
